Many original descriptions of beetles were published in Latin with specific idioms and technical terms, which are sometimes difficult to understand. The exact meaning of these descriptions is necessary for taxonomic and systematic research. Of the ten Palaearctic Plateumaris species regarded as valid three were described in English, the remaining seven in Latin, French, or German: P. amurensis Weise, 1898, P. bracata (Scopoli, 1772), P. consimilis (Schrank, 1781), P. roscida Weise, 1912, P. rustica (Kunze, 1818), P. sericea (Linnaeus, 1758), and P. weisei (Duvivier, 1885). These seven non-English original descriptions and their translations into English are presented here. Additionally, the translations of the first descriptions of the genus Plateumaris and of its 19 synonyms (some were described in Russian, also) are given.

Since Linnaeus (1758) many animal taxa have been described in Latin with very specific phrases used in scientific entomological scripts in the 18th and 19th centuries, which are not easily understandable for classicists who are not also entomologists. Furthermore, knowledge of the Latin language is in rapid decline. It is no longer part of the education curriculum of grammar schools, but was mandatory in Europe for centuries. Nowadays, English is the worldwide communication language used in science. The second author is a classicist and an entomologist with profound knowledge in systematics who translated numerous original Latin descriptions of Donaciinae taxa in the last years for systematic studies by the first author, such as Donacia clavareaui Jacobson, 1906 (Geiser 2019). Many translations are yet unpublished, but were used in Geiser and Jäch (2021).

First descriptions were also given in German, French, or Russian. These languages can be translated by electronic tools into understandable, but not always into directly printable English. However, these means do not offer the possibility to translate Latin into English. The Latin language was used for texts for more than 2000 years, for different purposes: in theology, law, medicine, philosophy, and scientific texts up to the 20th century, and in all these topics with different grammar and vocabulary rules. Even the Latin descriptions of beetles vary between beetle families. Also, they depended upon the specific education and on the preference of the authors. Therefore, “hand-made” or better “brain-made” translations by a knowledgeable specialist will provide the most adequate results.

In the update of the Catalogue of Palaearctic ChrysomelidaeDonaciinae (Geiser and Bezděk in press; Geiser in press) the first author made many changes concerning the taxonomy and systematics of the Plateumaris species compared with the first edition of the catalogue (Silfverberg 2010). These changes are explained in Geiser (2023). For such systematic revisions it was essential to study not only many specimens, but also the original descriptions.

In the genus Plateumaris 80 taxa were described for the Palaearctic region. Ten species names are regarded as valid, the other 70 are synonyms. We provide here the translations of the original descriptions of seven valid species (the other three were described in English) of the genus Plateumaris, and, additionally, of 19 taxa which are regarded as synonyms. These taxa are discussed in detail in Geiser (2023). Some original descriptions in other languages than Latin or English were also translated here into English. All these texts were essential for arguments why some systematic changes, especially synonymisations, were made in Palaearctic Plateumaris species.

Material and method

All original descriptions published in Latin were translated into German by the second author. Then the first author translated them into English. There also exist some original descriptions in German, which were translated into English by the first author. Some original descriptions were published in French, Russian, and Serbian. They were first translated into English by Google translate. Then the translations of French texts were revised together with Gloria Geiser. Translations of texts in a Slavic language were checked with Irmgard Geiser. Some original descriptions are multilingual. They begin in Latin, but often more details are explained in the author’s native language. The original orthography of the description is printed here, even though it is now outdated; the translation into English is as accurate and faithful as possible to the original text. The names of the Plateumaris taxa are arranged alphabetically, regardless of whether they are now synonyms or names of a valid species. The Palaearctic species P. akiensis Tominaga & Katsura, 1984, P. constricticollis Jacoby, 1885, and P. shirahatai Kimoto, 1971 are not included here because they were originally described in English.

Plateumaris amurensis Weise, 1898

Described on page 179. The German part of the text is shown in the original but the now-outdated orthography.

Latin English
Plateumaris amurensis Plateumaris amurensis
Oblonga, convexiuscula, obscure aenea, subtus cinereo-sericea, abdominis segmentis postice, ano, pedibus, ore antennisque dilute ferrugineis, his brevibus, articulo 3: o: 2: o longiore, Long, slightly convex, dark ore-coloured, underside silky grey, the abdominal segments from behind, anus, legs, mouth, and antennae are pale reddish brown, these [the antennae] are short, the third antennomere is longer than the second one, [3: o: 2: o is surely an error of the typesetter, presumably caused by misunderstanding of the [handwritten?] manuscript; the correct Latin description is: “articulo tertio secundo longiore” or “articulo 3° 2° longiore” or “articulo 3o: 2o longiore”]
prothorace brevi subcordato, disco dense ruguloso-punctato, subopaco, basi profunde arcuatim impresso, canalicula media sat profunda, angulis anticis minimis, acutis, elytris apice rotundato-truncatis, striato-punctatis, interstitiis nitidis, transversim strigosis, femoribus posticis dente valido armatis. the short prothorax subcordate, the disc is rugose and densely dotted, almost dark, at the basis a deep arcuate impression, the middle groove rather deep, anterior angles very small and acute, elytra at apex rounded truncate, with rows of punctures, intervals shiny, lean in transverse direction, hind femora armed with a stout tooth.
Long 7,5 mm. Length 7.5 mm

German English
Mit Pl. discolor verwandt, Fühler und Halsschild kürzer, letzteres viel unebener, erstere nebst den Mundtheilen, dem Hinterrande der Bauchringe und dem Aftersegmente hell rostroth. Related to Pl. discolor, antennae and pronotum shorter, the latter much more uneven, the former together with the mouth parts, the posterior margin of the abdominal segments and the anal segment pale rusty red.
Halsschild etwas breiter als lang, die Vorderecken bilden einen kleinen, aber scharfen Borstenkegel, die Seiten sind dahinter gerundet-erweitert, von ¼ der Länge ab allmählich nach hinten verengt, in der Mitte sanft ausgeschweift. Die Oberfläche ist uneben, dicht runzelig punktirt und mehr glänzend; sie fällt nach innen sanft zur scharfen Mittelrinne ab, die vor der Basis in einem tiefen, bogenförmigen Quereindrucke endet. So entstehen auf jeder Seite 2 niedrige Beulen, die vordere derselben ist kleiner als die hinter der Mitte. Pronotum slightly wider than long, the anterior angles form a small but sharp conical edge with bristles, behind it the sides are rounded-expanded, gradually narrowing backwards from ¼ of length, gently flared in the middle. The surface is uneven, densely rugose dotted and more lustrous; it slopes gently inwards to the sharp median groove, which ends with a deep, arched transverse impression before the basis. This creates 2 low tubercles on each side, of which the anterior one is smaller than the one behind the middle.
Die Flügeldecken sind wie bei den schwach sculptirten Exemplaren von discolor punktirt, die Punkte scharf eingestochen, die Zwischenstreifen glänzend, fein quer gerunzelt. Halsschild und Flügeldecken sind schwarzbraun, mit einem starken Messingschimmer. The elytra are punctured like the weakly sculptured specimens of discolor, the points are sharply engraved, the intervals are shiny and finely wrinkled transversely. The pronotum and elytra are blackish brown with a strong brassy lustre.
1) Aehnlich gefärbt ist die nahestehende Plateumaris Weisei Duviv. von Irkutsk (Jakowlew), welche Jacobsohn, Horae 26 p. 435 irrthümlich zu den Arten mit behaartem Halsschilde zählt. Das zweite Fühlerglied ist bei ihr stets halb so lang als das dritte, das Halsschild ähnelt dem von consimilis ist aber bedeutend schmaler und flacher, die Punktirung der Flügeldecken ist ziemlich dieselbe wie bei Donacia cuprea. 1) The nearby Plateumaris Weisei Duviv. from Irkutsk ([leg.] Jakowlew) is similarly coloured, which Jacobsohn, Horae 26 p. 435

Horae Societatis Entomologicae Rossicae 26: 412–437] erroneously aligned with the species with a hairy pronotum. The second antennal segment is here [concerning P. weisei] always half as long as the third one, the pronotum resembles that of [Plateumaris] consimilis but is significantly narrower and flatter, the puncturing of the elytra is rather the same as in Donacia cuprea [= Donacia semicuprea, Panzer, 1796].

Plateumaris annularis Reitter, 1920

German English
Plateumaris annularis Plateumaris annularis
Eine Art, die in der Mitte zwischen discolor und sericea steht, da sie zum Teil Eigenschaften der beiden vereinigt. Die Fühler sind auffallend dünn, von der Form, wie bei sericea, aber die Glieder breit gelbrot geringelt. Halsschild ebenso wie bei sericea, aber ohne längs der Mitte eingerissene Mittellinie und die Lateralbeulen ganz flach und nicht glänzend, die metallischen Schenkel und Schienen an der Basis fast bis zur Mitte gelbbraun, Pygidium und Apikalsaum des Analsternites rot ; kupferig, erzfarben. A species that stands in the middle between discolor and sericea, since it partly combines characteristics of both. The antennae are remarkably thin, the same form as in sericea, but the segments are broadly annulated in yellow-red. Pronotum as in sericea, but without median line engraved along the centre, and the lateral tubercles quite flat and not shiny, the metallic femora and tibiae from the base almost to the middle yellow-brown, pygidium and apical margin of anal sternite red; coppery, bronze.

Plateumaris caucasica Zaytsev, 1930

Described on page 111. Synonym of P. sericea.

Latin English
Plateumaris caucasica Plateumaris caucasica
♂♀. Species inter sericea L. et discolor Panz. intermedia, sed illius manifeste affinior. ♂♀. Intermediate species between sericea L. and discolor Panz., but clearly closer to the former.
Ab ambobus differt pedum colore: femoribus in triente basali, tibiarum parte ¾ longitudinis (nonnunquam usque ad apicem), tarsorum articulis omnibus (ultimo saepe excepto), segmentorum abdominalium summo margine, pygidio rufo-ferrugineis. It differs from both by the colour of the legs: the femora at the basal third, the tibiae at 3/4 of the length (sometimes up to the apex), all tarsomeres (often except the last one), the very margin of the abdominal segments and the pygidium are reddish-rubiginous.
Praeterea a P. sericea discrepat corporis forma robustiore, subtus brevius pubescente, antennis gracilioribus atque longioribus, rubro-castaneis, articulis solum apice vel nihilo obscuratis, pronoto fortius ruguloso (fere ut in P. dicolor [sic!]) angulis anticis haud prominulis; ceterum cum P. sericea congruens. Further it differs from P. sericea by a more sturdy, ventrally shorter and densely pubescent physique, more slender and longer testaceous antennae with antennomeres darkened only at the apex or nowhere, a more rugose pronotum (almost like P. dicolor [sic!]) with not protruding anterior angles; otherwise consistent with P. sericea.
A. P. discolor magis adeo distat antennis gracilibus, articulo quarto quam secundo duplo longiore etc. Superficiei colore variat viride vel aurichalceo. Many more differences exist compared with P. discolor by more slender antennae, the fourth antennomere which is twice as long as the second one etc. The surface colour varies between green and brassy.
Long. 7–8,5 mm. Length 7–8.5 mm.

Probably very close to P. annularis Reitt[er] (from the Amur Prov[ince]), but it seems that our species differs according to the author’s description by a smaller body and more extensively red-coloured tibiae.
Russian English
Хотя указанных сейчас отличий от восточно-сибирского
вида и недостаточно для признания видовой самостоятелъности за нашей формой, но разорванностъ ареалов обитания, лаконичностъ описания у Reitter’a и отсутствие для сравнения
амурских представителей этого вида дают основания пока считатъ их различными видами.
Although the differences now indicated from the East Siberian species are not enough to regard this form as an independent species, the fragmentation of the habitats, the brevity of Reitter’s description and the lack of comparison with specimens from the Amur give reasons to consider it as a different species for the time being.

Dessous du corps d’un noirâtre un peu bronzé, revêtu d’une pubescence soyeuse, argentée, très serrée. Underside of the body a little tanned blackish, covered with a silky, silvery, very dense pubescence.
Pattes de la même couleur, courtes épaisses, cuisses très renflées, les postéreures munies d’une forte dent triangulaire. Legs of the same colour, short thick, very swollen thighs, the posterior ones provided with a strong triangular tooth.
Elle se place dans la mème division que la D. sericea L. et elle a de grands rapports avec elle. Elle en diffère néanmoins par de caractères bien tranchés. Les tubercules placés derrière les angles antérieurs du prothorax sont moins saillants ; à partir de ces tubercules les côtes sont un peu arqués en dedans dans la sericea et la base finit par avoir ls même largeur que le sommet; dans la Lacordairii le prothorax se rétrécit au contraire insensiblement jusqu’à la base en s’arrondissant très légèrement ; il est en outre plus court. Les ponts des stries des élytres sont plus rapprochés, et par-dessous tout les pattes sont plus courtes, plus épaisses et les cuisses sensiblement plus renflées. It is placed in the same division as D. sericea L. to which it is closely related. However, it differs from it by well-defined characters. The tubercles placed behind the anterior angles of the prothorax are less protruding; from these tubercles the ridges are arched inwards in sericea, and the base ends up with the same width as the anterior part; in Lacordairii the prothorax narrows, on the contrary, imperceptibly to the base, rounding out very slightly; it is also shorter. The bridges of the elytral striae are closer together, and below all the legs are shorter and thicker, and the thighs noticeably more swollen.
J’ai pris cette espèce en Espagne, aux bords d’un ruisseau sur la route de la Granja à San Rafaël. Je la dédie à mon illustre ami M. Lacordaire, comme témoignage d’affectueuse admiration pour son caractère et ses travaux. I caught this species in Spain, on the banks of a stream at the road from La Granja to San Rafaël. I dedicate it to my illustrious friend M. Lacordaire, as a testimony of affectionate admiration for his character and his work.

(affinis Kunze) *), to which it is closest, it differs above all by the weaker stature, by the more delicate antennae with consistently longer antennomeres, the 4th one clearly longer than the previous one, by the narrower pronotum with sides more swollen behind the anterior corners, almost dentiformly protruding outwards, by the more sparsely dotted, lighter disc, by the elytra more abruptly narrowed towards the end, with a little narrower dot-stripes on the back, by the bulging-raised first interval from the end of the stripe next to the scutellum, by the 9th one forming a shortened fold behind the shoulder, by the lower edge of the seam more gaping further back, by the simple and short basal abdominal segment in the ♂, by the metasternum, which is also not impressed, by the hind femora armed with a stronger and more blunted tooth in the same sex, by the more delicate tibiae, etc.
*): Donacia abdominalis Olivier is now synonym with Plateumaris bracata and not with P. affinis Kunze.

Above all, from Don. consimilis Schrank, to which it is also closely related, it differs by the same characters as from D. abdominalis. Furthermore, it also differs in the colour of the antennae and legs from Don. rustica Kunze.

From D.n. Weisei Duviv. 17)
it differs above all by the shiny and not densely dotted pronotal disc, with tooth-shaped and outwards protruding front corners, by dark elytra with the first interval behind the stripe next to the scutellum, which is very bulging and raised, and the 9th one behind the shoulder that is briefly folded up. –Nevertheless, it is easily possible that m[y] D. mongolica is just a simple aberration of the male of Donacia Weisei (which is totally unknown to me).
16) Genus Plateumaris (C. G. Thoms.) Weise, Jacobs. ad gradum subgeneris reducendum esse censeo; nam nonnullae species orientali-asiaticae, imprimis Plateumaris excisipennis Jacobs. (Horae Soc. Ent. Ross., XXVIII, 1894, p. 241), cujus in descriptione auctor sexum speciminis originalis unici indicare verisimiliter invitus neglexit, transitum nimis manifestum ad genus Donacia F. praebere videntur. Ceterum praesumo Donaciam excisipennem (Jacobs.) subgenus proprium constituere. 16) I think that the genus Plateumaris (C. G. Thoms.) Weise, Jacobs. should be relegated to the category of a subgenus; because a number of East Asian species, above all Plateumaris excisipennis Jacobs. (Horae Soc. Ent. Ross., XXVIII, 1894, p. 241), where the author probably reluctantly failed to indicate the sex of the only original specimen in its description, seems to provide a very clear transition to the genus Donacia F. Incidentally, I suspect that Donacia excisipennis (Jacobs.) establishes its own subspecies.

Convexiuscula, aurichalcea; corpore subtus, capite, scutello, pedibus antennisque argenteo-tomentosis. Cuput [sic! a typing error, it should be: Caput] densissime punctatum, linea media impressa frontis tenui, profunda. Slightly convex, brass coloured; underside of the body, the head, the scutellum, legs and antennae silvery tomentose. The head extremely densely punctured, the impressed narrow median line in the head deep.
Antennae dimidio corpori longitudine aequales, sed multo magis tenues quam in P.. discolore, articulo primo crasso, ceteris subtilibus, articulo 2° sesqui breviore quam tertius, 4° hoc sesqui longiore, ceteris subaequali; articulorum 2i–11i basibus rufo-ferrugineis. Antennae in length equal to half the body, but much thinner than in Pl. discolor, the first segment thick, the others fine, the 2nd segment is half as short as the third one, the 4th one by half longer than this one, the rest almost the same; the basis of the 2nd–11th segment is reddish-rusty brown.
Prothorax latitudine multo longior, disco subplano, lateribus subparallelis; tuberculo laterali minime convexo, parum determinato; angulis omnino non prominulis, rectis; linea
longitudinali disci vix distincta; disco subtilissime remote punctato, inordinate subtiliter et dense ruguloso, nudo, sericeo-opaco (basi nitida excepta).
Prothorax much longer than wide, the disc nearly flat, the sides nearly parallel; lateral tubercles minimally convex, not very pronounced; the angles not a bit protruding, straight; the longitudinal line of the disc scarcely pronounced; the disk very finely widely punctured, irregularly, finely and densely wrinkled, hairless, silky dusky (except the shiny base).

Plateumaris consimilis orientalis Plateumaris consimilis orientalis
Corpore supra splendidiore, rugulis striarum interstitiorum elytrarum humilioribus, dente femorum posticorum minore vel obsoleto. Body shinier above, the wrinkles between the grooves of the elytra lower, tooth on the hind femora smaller or extinct.
Russian English
Размеры тел и соотношение длин и ширин всех частей те же, что и у типичной формы, но тело значителъно более блестящее, благодаря менее грубой скулъитуре надкрылий. The dimensions of the body and the ratio of the lengths and widths of all parts are the same as in the typical form, but the body is much more lustrous due to the less coarse sculpture of the elytra.
Точечные ряды надкрылий менее углублены, поперечные морщины промежутков, как основные так и мелъчайшие, выражены менее резко и более сглажены. Пунктировка в основаниях надкрылий более тонкая и менее спутанная. Переднеспика с более резким перехватом за боковыми бугорками. The dotted grooves of the elytra are less deepened, the transverse wrinkles of the intervals, both the basal and the tiny ones, are less pronounced and smoother. The punctuation at the basis of the elytra finer and less confused. The pronotum with a sharper recess behind the lateral tubercles.
Задние бедра ♀без зубца или с незначителъным бугорком на его месте. Верхняя сторона бронзово – медная с зеленоватым оттенком. Четыре последних брюшных стернита, усики и ноги – краснобурые. Волоски нижней стороны и конечностей золотистые или желтоватые. Hind femora of ♀without tooth or with a slight tubercle in its place. The upper side is bronze-copper with a greenish tint. The last four ventral sternites, antennae, and legs are reddish brown. Underside the hairs and limbs are golden or yellowish.

Plateumaris consimilis Schrank в прошлом столетии считался видом, распространенным по всей средней и южной Европе и, кроме того, в Сибири (Якобсон, 1892) и в Яапонии (Jacoby, 1885) посколъку в литературе были указания для Иркутска (Солъский, окодо 1870 г.) Урала (Редикорцев, 1908) и Японии (Jacoby, 1885) [originally written: Jacobi], относящиеся к виду Plateumaris discolor Hoppe (= P. consimilis Schrank). Других указаний не были, в промежуточных местностях вид тоже нигде наиден не был. Clavareau (1913) и Reitter (1920) давали без измененй те же сведения, что и Якобсон. In the last century Plateumaris consimilis Schrank was considered as a species distributed throughout central and southern Europe and furthermore in Siberia (Jakobson, 1892) and Japan (Jacoby, 1885), since there were indications in the literature for Irkutsk (Solsky, about 1870), Ural (Redikortsev, 1908) and Japan (Jacoby, 1885) belonging to the species Plateumaris discolor Hoppe (= P. consimilis Schrank). There were no other indications, and the species was not found anywhere in localities in between either. Clavareau (1913) and Reitter (1920) give the same unmodified information as Jacobson.
По категорическому утверждению Колосова (1930)’, P. consimilis Schrank есть чисто западноевропейский вид, восточная граница которого (по материалам его коллекции) проходит по территории Польши, а указания на более восточные местонахождения не верны и относятся к другим видам. According to the categorical assertion of Kolossow (1930), P. consimilis Schrank is a purely Western European species, whose eastern boundary passes through the territory of Poland (according to the materials of his collection), while records from more eastern localities are not correct and refer to other species.
Теперь же нахождение данного вида под Владивостоком вносит полную ясность и подтверждает правильность старых указаний для Иркутска и Японии или во всяком случае очень большую вероятность их. But now the occurrence of this species near Vladivostok brings complete clarity and confirms the correctness of the old records from Irkutsk and Japan, or at least a very high probability.
Вместе с тем мы имеем теперь сборы P. consimilis Schrank из Черниговской и Полтавской областей и можем считать его видом не только западно-европейским. Указание для Урала (Редикорцев), сделанное по литературным источникам середины прошлого столетия, можно считать лишь вероятным. At the same time, we now have collections of P. consimilis Schrank from the Chernigov and Poltava regions [both sites are in the Ukraine], so we can consider it as a species not only of Western Europe. The indication for the Ural (Redikortsy), made according to the literary sources from the middle of the last century, can only be considered as probable.
Наличие P. consimilis Schrank на Дальнем Востоке именно в форме особой расы при условии такого большого территориального разрыва предста-вляется вполне естественным. Структурные различия от западно формы в виде большего блеска и меньшей морщинистости надкрылий, дерехвата переднеспинки и более светлого пвета ноги усиков совершенно аналогичны таким же признакам у дальневосточных подвидов других видов донаций, нак, например, D. clavipes glabrata Solsky, D. obscura splendens Jacobs. и D. thalassina rufovariegata Jacobs. The presence of P. consimilis Schrank as a separate race in the Far East seems quite natural given such a large territorial distance. Structural differences from the western form by stronger shine and less wrinkling of the elytra, the more straight-lined pronotum, and a lighter coloration of the antennae are completely analogous to the same characters in the Far Eastern subspecies of other Donacia species, like, for example, D. clavipes glabrata Solsky, D. obscura splendens Jacobs. and D. thalassina rufovariegata Jacobs.
Пробел между ареалами западной и восточной форм, возможно, будет ваполнен при более подробном изучении фауны СССР, и мы, быть может, получим довольно непрерывное распространение вида с запада на восток, но это только подтвердит наличие довольно типичного восточного подвида Plateumaris consimilis orientalis. The gap between the distribution areas of the western and eastern form will probably be filled by a more detailed study of the fauna of the USSR, and we may have a fairly continuous distribution of the species from west to east, but this will only confirm the presence of a rather typical eastern subspecies Plateumaris consimilis orientalis.

Von rustica habe ich bis jetzt nur ein Stück aus Krain von Stussiner erhalten, welches auf dem Rücken angedunkelte Schenke besitzt, bei den übrigen sind die Beine einfarbig rost-roth. Zwischen normal gefärbten Exemplaren fing Herr A. Fiori in der Umgegend von Modena (Emilia: Jala, März 1894) nun auch abweichende Stücke, von denen er mir ein oberseits schwarzes, auf dem Halsschilde bläulich schimmerndes M und 2 W schickte. Bei ihnen sind die Beine pechschwarz’, in den Gelenken dunkel rostroth, oder einfarbig schwarz. Es ist möglich, dass diese Varietät auch noch in Deutschland aufgefunden wird. Until now I have received only one specimen of rustica from Stussiner from Carniola, with femora darkened on their upper side, all others have legs which are uniformly rufous. In the vicinity of Modena (Emilia: Jala, March 1894) Mr. A. Fiori now also caught differing specimens between normally coloured specimens, from which he sent me a ♂ which is black on the upper side and shimmering bluish on the pronotum, and 2 ♀. Their legs are pitch-black, darkly rufous in the joints, or plain black. It is possible that this variety will also be found in Germany.

Plateumaris sachalinensis Medvedev, 1973

Described on page 876. Synonym of P. weisei.

Russian English
Plateumaris sachalinensis Plateumaris sachalinensis
Бронзово-зеленый или медный, переднеспинка красновто-медая, основания всех члеников усиков, а также основания бедер и голеней рыжпе, задние края стернитов брюшка с желто-рыжей окантовкой. Bronze-green or cupreous, pronotum medium-reddish, bases of all antennal segments, as well as bases of femora and tibiae rufous, posterior margins of abdominal sternites with a yellow-rufous fringe.
Верх слабо блестящий, лобные бугры оченъ слабые, усики тонкие, длинные, как у P. weisei Duv., задние бедра с оченъ слабым, едва выступающим зубцом. Вершина пигидия и последний стернит брюшка притупленно округленные. Длина тела 6.6–7.1 mm. Эдеагус с зкозаостренной вершиной, снизу блестящий, в сглаженной продолъной морщинистости, парамеры значителъно не достигают вершины эдеагуса, с перетяжкой у основания. Upper side slightly shining, frontal tubercles very weak, antennae thin, long, like in P. weisei Duv., hind femora with a very weak, barely protruding tooth. The apex of the pygidium and the last sternite of the abdomen are obtusely rounded. Body length 6.6–7.1 mm. Aedeagus with sharply pointed apex, shining ventrally, with smoothed longitudinal rugosity, parameres do not significantly reach the apex of the aedeagus and are constricted at the base.
Описываемый вид относится к номинативному подроду и наиболее близок к P. obsoleta Jacobs., от которого отличается двупветнй окраской ног. От P. weisei Duv. и P. amurensis Wse. отличается окраской ног и слабым зубцом на задних бедрах. Очевидно, вид занимает промжуточное положение между группой P. sericea и группой P. weisei. Надо скзатъ, что сравнение нового вида с P. obsoleta Jacobs., известного по единственной самке, затруднено тем, что в нашем распоряжении имелисъ толъко самцы. The described species belongs to the nominative subgenus [Plateumaris was regarded as subgenus of Donacia by some authors] and is closest to P. obsoleta Jacobs. From P. weisei Duv. and P. amurensis Wse. it differs in the coloration of the legs and a weak tooth on the hind femora. Obviously, the species occupies an intermediate position between the P. sericea group and the P. weisei group. It must be said that the comparison of the new species with P. obsoleta Jacobs., known from a single female, is difficult, because we had only males at our disposal.

Seiten hohe Längswülste bilden, das glänzende Halsschild, dessen beiderseits abgekürzte Mittelrinne am Anfange und Ende tief und scharf, in der Mitte flach ist und neben der sich jederseits ein sehr flacher, spiegelglatter Höcker befindet, sowie die völlig ungezähnten Hinterschenkel sicher verschieden.
Similar to Plat. rustica and affinis, to be placed next to the latter, more elongated than both, certainly different due to the deep and broad frontal furrow, whose sides form high longitudinal ridges, the shiny pronotum, whose median groove, which is shortened on both sides, is deep and sharp at the beginning and the end, flat in the middle, and next to which there is a very flat, mirror-smooth tubercle on each side, as well as the completely unarmed hind femora.

Plateumaris tenuicornis Balthasar, 1934

Described as Plateumaris (Juliusina) tenuicornis on page 128. Synonym of P. consimilis.

German English
Plateumaris tenuicornis Plateumaris tenuicornis
Der Pl. consimilis Schrank äußerst nahestehende Art, mit ihr auch wahrscheinlich bisher vermengt. A species very closely related to Pl. consimilis Schrank, with which it has also probably been confused till now.
Kopf sehr dicht und fein punktiert, mit einer scharfen, länglichen Rinne, die Erhabenheiten an der Wurzel der Fühler nur mäßig, die Augen sehr stark vorgequollen, die Schläfen stark entwickelt, mächtig hervorragend, nach hinten deutlich konvergierend. Die Halspartie stark eingeschnürt, daher auffällig akzentiert. Fühler sehr schlank, die einzelnen Glieder zur Spitze nur mäßig verstärkt. Head punctured very densely and finely, with a sharp, elongated groove, the elevations at the base of the antennae are only moderate, the eyes are very protruding, the temples are well developed, powerfully prominent, clearly converging towards the base. The neck area is severely constricted, therefore conspicuously accentuated. Antennae very slender, the individual segments only moderately widened towards the tip.
Halsschild mit einer ziemlich deutlich angedeuteten Mittelfurche, auf der Scheibe nicht besonders dicht, aber ziemlich fein punktiert, dazwischen äußerst fein chagriniert, nur an den Seiten mit kaum wahrnehmbaren anliegenden Härchen (erst bei der Vergrößerung, 40×, Zeiß, binokulares Mikroskop) besetzt. Die Seitenbeulen ziemlich stark entwickelt, die Seiten nach hinten stärker zusammenlaufend, die Vorderwinkel spitzig vorragend. Pronotum with a fairly clearly indicated central furrow, punctured on the disc not particularly densely, but quite finely, extremely finely shagreened in between, only on the sides overgrown with barely perceptible flat small hairs (only by magnification, 40×, Zeiss, binocular microscope). The side tubercles fairly well developed, the sides tapering more towards the end, the front angles pointedly prominent.
Flügeldecken ziemlich fein in Längsreihen punktiert, die Zwischen- räume sehr fein und sehr dicht quergerunzelt, zur Basis vollkommen flach, gegen die Spitze mäßig gewölbt. Unterseite seidenglänzend, dicht, kurz, anliegend behaart. Elytra rather finely punctured in longitudinal rows, the intervals very finely and very densely wrinkled transversely, completely flat at the base, moderately convex towards the apex. Underside silky shiny, dense, short, hairy.
Hinterschenkel nur mit kleinem Zähnchen (beim ♀), die Schienen verhältnismäßig schlank. Hind femora only with small teeth (♀), the tibiae relatively slender.
L. 6.5 mm L[ength] 6.5 mm
Oberseite grün, ziemlich matt erscheinend, Beine und Fühler hell gelbrot. Upper surface green, appearing rather dull, legs and antennae pale yellow-red.

Von der sehr verwandten Art Pl. consimilis Schrank durch folgende Merkmale ziemlich schwer, aber sicher zu unterscheiden: Fühler auffallend schlanker, Augen sehr stark vorgequollen, die Schläfen nach hinten konvergierend, nicht parallel und viel mehr akzentiert, Hals sehr deutlich stärker eingeschnürt, schmäler, die Lateralbeulen des Halsschildes deutlicher, oben tiefer abgegrenzt, der Halsschild schmäler, nach hinten stärker zusammenlaufend. Außerdem sind die Vorderwinkel mehr seitlich gerichtet und spitziger. Die Flügeldecken bei der neuen Art (im Falle, daß die Skulptur vollkommen konstant ist) scheinen viel feiner und dichter skulptiert zu sein. Im ganzen subtiler gebaut und kleiner. Rather difficult to distinguish but surely from the very related species Pl. consimilis Schrank by the following characters: antennae noticeably slimmer, eyes very much bulging, temples converging backwards, not parallel and much more accentuated, neck much more constricted, narrower, the lateral bulges of the pronotum more distinct, more deeply demarcated above, the pronotum narrower, converging more towards the end. In addition, the front angles are more laterally directed and more pointed. The elytra in the new species (in case the sculpture is perfectly constant) appear to be much finer and more densely sculptured. On the whole built more subtly and smaller.

Bechyné (1942) wrote in a paragraph that Plateumaris tenuicornis Balthasar looks the same as P. consimilis. This article was ignored for decades, perhaps because it was printed in Czech and Latin. Here the part of that article that deals with P. tenuicornis in Latin is copied and translated into English.

Secundum exempl. quae ante oculos habeo, Pl. consimilis et Pl. tenuicornis haud specifice differunt. Variat enim Pl. consimilis in characteribus sequentibus: in longitudine corporis, in convexione oculorum, in forma temporum, in forma singulorum articulorum antennarum, in punctatione capitis, prothoracis elytrorumque nec non in forma angulorum anticorum pronoti, in dentibus femorum posteriorum etiamque in colore species haec maximam variationem demonstrat.
In this work I provide a review of Plateumaris tenuicornis Balthasar, Entom. Newsletter VIII, 1934, pp. 128–129.
According to the specimens on hand, there are no typal differences between Pl. consimilis and Pl. tenuicornis. That is to say Pl. consimilis varies in the following characters: In the length of the body, in the curvature of the eyes, in the shape of the temples, in the shape of the individual antennal segments, in the dotting of the head, the prothorax and the elytra and also in the shape the front angles of the pronotum, in the teeth of the hind femora and also in the colouring this species shows a very large variability.

Plateumaris weisei (Duvivier, 1885)

Described as Donacia (Plateumaris) weisei on page cxvi [116].

French English
Donacia weisei Donacia weisei
Corps oblong, rétréci en arrière, d’un bronzé verdâtre ou d’un violet foncé, couvert en dessous d’une pubescence d’un gris argenté assez dense, avec les pattes, les antennes et la bouche ferrugineuses; corselet allongé, presque plan en dessus, très-rétréci en arrière, sillonné à la base, densément ponctué; élytres allongées, ponctuées-striées, à intervalles ridés transversalement, peu convexes, rétrécies en arrière. Body elongated, back narrowed, greenish-brown or dark purple, ventrally covered with a fairly dense silvery-grey pubescence, legs, antennae and mouth rufous; pronotum elongated, almost flat above, very narrow behind, furrowed at the base, densely punctured; elytra elongated, with punctured stripes, at the intervals transversely wrinkled, not very convex, narrowed behind.
♂ Plus petit, étroit, allongé; antennes des 2/3 de la longueur du corps.
♀ Plus grande, large, robuste; antennes de la ½ de la longueur du corps.
Long. 7 to 7 ¾ mill. – Sibérie (H. Deyrolle).
♂ Smaller, narrow, elongated; antennae 2/3 the length of the body.
♀ larger, broad, sturdy; antennae ½ the length of the body.
L[ength] 7 to 7 ¾ mm – Siberia (H. Deyrolle).
♂ Corps allongé, étroit, rétréci en arrière, d’un beau vert bronzé ou d’un violet foncé en dessus. Bouche ferrugineuse. Tête marquée d’un profond sillon longitudinal plus ou moins prolongé en arrière, finement rugueuse, profondément ponctuée. Yeux noirs, assez saillants. ♂ Body elongated, narrow, back narrowed, of a beautiful bronze-green or dark purple above. Mouth rufous. Head marked with a deep longitudinal groove more or less long, finely rugose, deeply punctured. Black eyes, rather prominent.
Antennes des 2/5 de la longueur du corps, ferrugineuses, à art. 3–4 subégaux, le 3e (= third) cependant un peu plus court et plus robuste que le suivant. Prothorax un peu plus long que son plus grand diamètre transversal et assez fortement rétréci en arrière; coupé carrément en avant, légèrement arrondi et subsinué à la base, à angles peu distincts; angles antérieurs suivis en arrière d’un renflement arrondi, occupant les 2/5 des côtés, nettement limité en dessous par une dépression assez marquée provoquant en cet endroit un rétrécissement du corselet; disque presque plan, couvert de points, enfoncés, très-serrés et confluents, sans sillon dorsal, ayant, près de la base, un sillon transversal anguleux n’atteignant pas les côtés. Antennae 2/5 of body length, rufous, with antennomeres 3–4 nearly equal, the 3rd one however a little shorter and more robust than the next one. Prothorax slightly longer than its greatest transversal diameter and quite fiercely narrowed posteriorly; cut squarely in front, slightly rounded and emarginate at the base, with slightly distinct angles; anterior angles followed behind by a rounded swelling, occupying 2/5 of the sides, clearly limited below by a fairly marked depression causing in this spot a narrowing of the pronotum; disc almost flat, covered with dots, sunken, very close and confluent, without a dorsal groove, near the base with an angular transverse groove not reaching the sides.
Ecusson en triangle curviligne, ponctué. Elytres oblongues, très-rétrécies en arrière, finement ponctuées-striées, à points très rapprochés; intervalles entre les stries à peine relevés, couverts de fines rugosités transversales. Dessous coloré comme le dessus, avec l’extrémité abdominale ferrugineuse, couvert d’une pubescence d’un gris argenté assez dense. Pattes ferrugineuses, cuisses postérieures légèrement renflées, munies près de leur extrémité d’une dent triangulaire de dimension variable. Scutellum punctured. Elytra elongated, distinctly narrowed behind, finely punctured-striated, with very close dots; intervals between the stripes barely raised, covered with fine transverse wrinkles. Underside coloured like above, with a rufous abdominal apex, covered with a fairly dense silvery grey pubescence. Legs rufous, hind femora slightly bulging, provided near to their end with a triangular tooth of variable size.
♀ Forme plus robuste, corselet relativement plus large, antennes n’atteignant que la moitié de la longueur du corps. ♀ Shape more robust, pronotum relatively wider, antennae reaching only half the length of the body.
Cette espèce est très-voisine de D. discolor Hoppe; elle en diffère par sa forme plus svelte, plus étroite, sa taille plus petite, son corselet plus allongé, plus rétréci en arrière, avec ses côtés non régulièrement arrondis mais renflés légèrement sur le premier tiers, par l’absence de sillon longitudinal sur le prothorax, par ses élytres plus étroites et la dent triangulaire des fémurs postérieurs moins saillante. This species is closely related to D. discolor Hoppe [= synonymous with Plateumaris consimilis Schrank]; it differs from it by its more slender, narrower shape, its smaller size, its more elongated pronotum which is more narrowed behind, with its sides not regularly rounded but slightly swollen on the first third, by the absence of a longitudinal groove on the prothorax, by its narrower elytra and the less prominent triangular tooth of the hind femora.
Je dédie cette espèce à notre collègue, M. Julius Weise de Berlin, à qui la science entomologique est redevable de sérieux travaux sur les Phytophages. I dedicate this species to our colleague, Mr. Julius Weise from Berlin, to whom entomological science is indebted for serious work on Phytophages.


There are ten Palaearctic Plateumaris species regarded as valid: three of them were described in English (P. akiensis, P. constricticollis, P. shirahatai), six in Latin (P. amurensis, P. bracata, P. consimilis, P. roscida, P. rustica, P. sericea), and one (P. weisei) was originally described in French. In general, most of the original descriptions of Plateumaris taxa are in Latin or began with a Latin diagnosis at least, and further explanations were then added in German, Russian, or French in most cases.

In addition to the first descriptions of the valid species in the Palaearctic, another 19 original descriptions are presented here with their translations and the species names published therein are now regarded as synonyms. Mostly, these are names which were synonymized or their synonymisation was confirmed in Geiser (2023). This list is not complete, because more than 70 names are now known to be allocated to one of the ten valid Plateumaris species. We intend to continue publishing translations of original descriptions of Donaciinae taxa. Furthermore, we encourage other colleagues to do the same in their areas of expertise.

The Latin first description of the genus Plateumaris established by Thomson (1859) and its translation are also given here. At first, Donaciinae species were assigned to the genus Leptura by Linnaeus (1758). Later, Fabricius (1775) established the genus Donacia, but did not change the genus name of Leptura sericea. Later, some authors described Plateumaris species with Donacia as the genus name, even after Thomson had established the name Plateumaris. Some authors regarded Plateumaris only as a subgenus of Donacia, and these opinions are reflected in the first descriptions. For more details see Geiser (2023).


Although many original descriptions printed in the 18th or 19th centuries are available online today, we benefitted from the huge literature collection about Chrysomelidae of Jan Bezděk (Brno, Czechia). Wolfgang Brunnbauer (Vienna, Austria), the former librarian of the Natural History Museum Vienna, tracked down literature that seemed to be unavailable. We also had additional linguistic help from Gloria Geiser (Salzburg, Austria) with French and from Irmgard Geiser (Salzburg, Austria) with Slavic languages. Many thanks to all of them. We would also like to thank the editorial team, especially Caroline Chaboo (Lincoln, Nebraska, USA), the reviewer Michael Schmitt (Greifswald, Germany) and an anonymous reviewer for their advice to improve our manuscript, and Nathalie Yonow (Swansea, United Kingdom) for the linguistic corrections.
