The genus Biston Leach, 1815 is reviewed for China. Seventeen species are recognized, of which Biston mediolata sp. n. is described. Biston pustulata (Warren, 1896) and Biston panterinaria exanthemata (Moore, 1888) are newly recorded for China. The following new synonyms are established: Biston suppressaria suppressaria (Guenée, 1858) (= Biston suppressaria benescripta (Prout, 1915), syn. n. = Biston luculentus Inoue, 1992 syn. n.); Biston falcata (Warren, 1893) (= Amphidasis erilda Oberthür, 1910, syn. n. = Amphidasis clorinda Oberthür, 1910, syn. n. = Biston emarginaria Leech, 1897, syn. n.); Biston panterinaria panterinaria (Bremer & Grey, 1853) (= Biston panterinaria abraxata (Leech, 1889), syn. n. = Biston panterinaria lienpingensis (Wehrli, 1939), syn. n. = B. panterinaria szechuanensis (Wehrli, 1939), syn. n.). Biston falcata satura (Wehrli, 1941), comb. n. is proposed. A key to Chinese Biston and diagnoses for Chinese species are provided. Illustrations of external features and genitalia are presented.
Biston, taxonomy, new species, Geometridae, Lepidoptera
Biston indeed has some typical features in common with the Boarmiini:
the postmedial lines of both wings often protrudes outwards between M1
and M3; in the male genitalia, the socii are usually absent; the valva
has a strong cucullus. However, Biston also has some features atypical for Boarmiini: a fovea is absent in the male forewing; in the male genitalia, the valva is simple, without any ornamentation (
The species of Biston
are widely distributed in Holarctic, Oriental and Ethiopian regions.
Reviews of the genus are available for some geographical regions, e.g.
for Africa (
Here, we divide the Chinese Biston into three species groups based on morphological characters. Group I includes the “typical” species of Biston. Group II includes Biston brevipennata Inoue, 1982 and the species which were treated in the subgenus Eubyjodonta of Biston by
The purpose of this paper is, to review all known Chinese Biston species, to determine their diagnostic characters, to develope a key for their determination and to provide illustrations of external features and genitalia; furthermore, one new species, Biston mediolata sp. n., will be described, Biston pustulata (Warren, 1896) will be recorded as new for the fauna of China and several new synonyms and a new combination will be proposed. This results, to our present knowledge, in 17 species and nine subspecies of Biston for the fauna of China and 52 species with 33 subspecies worldwide.

http://species-id.net/wiki/Biston
Head. Antennae bipectinate in male, rami short, moderately long or long, length tapering towards apex, often the distal part of antennae without rami; filiform in female (Figs 1–3). Frons not protruding, smooth-scaled. Tongue well developed. Labial palpus small, with hair-scales, not extending beyond frons. Compound eyes setose.
Thorax. Legs covered with hair-scales. Hind tibia slightly dilated, with two pairs of spurs in both sexes, without hair-pencil. Frenulum developed. Forewing without basal fovea in male, triangular, outer margin straight or waved, hindwing round, outer margin smooth, sometimes concave between M1 and M3 or protruding between M1 and CuA1. Wings white, pale yellow or greyish brown, transverse lines black, brown or white. Pattern of forewing: antemedial line slightly waved, often accompanied by a band basally; medial line waved, usually inconspicuous; postmedial line waved or dentate, sometimes protruding outwards between M1 and M3 and between CuA2 and 1A + 2A, often accompanied by a band posteriorly; submarginal line sometimes indistinct; terminal line sometimes appearing as a series of short stripes between veins; discal spot black or grey, shortly strip-like, dot-like or elliptic, pale-centred. Hindwing sometimes with basal line; medial line often indistinct, sometimes double; postmedial line waved or dentate, sometimes protruding outwards between M1 and M3; terminal line similar to those of forewing; discal spot sometimes smaller and less conspicuous than on forewing. Terminal spots occasionally present on both wings, wedge-shaped. Underside paler, transverse lines often similar to those of dorsal surface.
Venation. Forewing: Sc free, R1 and R2 usually stalked (separate in Biston thoracicaria), diverging before anterior angle of cell; R2 sometimes connected by a short transverse bar with R3–4 or R3–5; R3–5 before or from anterior angle of cell, not stalked with M1; M1 from anterior angle of cell; M3 from posterior angle of cell; CuA1 before posterior angle of cell. Hindwing: Sc+R1 close to cell less than onehalf length of cell; Rs before anterior angle of cell; M1 from anterior angle of cell; M2 absent; M3 from posterior angle of cell; CuA1 before or from posterior angle of cell; 3A absent.
Abdomen. Dorsum scattered with transverse lines or dots, sometimes with anal tuft. Third sternite of male abdomen without setal patch. Intersegmental membrane between abdomen and genitalia densely covered with elongate scales which partly developed to spines in a few species.
Male genitalia. Uncus short and broad, ratio of length to basal width variable, often bifurcate terminally, sometimes bifurcation very shallow or on ventral side below apex, so the latter apparently square or round. Arms of gnathos connected medially, with median process robust or slender, round, acute or square terminally. Valva simple; costa sclerotized, straight or incurved, with terminal half often broadened, bearing long setae from center to apex; sacculus sometimes sinuous. Saccus round or semicircular. Juxta well developed, pointed, or round or flat apically, sometimes elongate, without lateral brushes of long setae, except in Biston melacron Wehrli, 1941. Aedeagus often cylindrical, sclerotized dorsally; vesica usually wrinkled, scobinate, with or without cornuti; shape of cornuti various.
Female genitalia. Papillae anales covered with dense setae, occasionally elongate. Apophyses posteriores usually very long. Lamella postvaginalis sometimes present, oval or almost triangular. Ostium bursae occasionally weakly sclerotized. Ductus bursae striated longitudinally, sometimes sclerotized. Corpus bursae often long, membranous, sometimes curved medially, swollen anteriorly, often bearing a signum; signum elliptic, bar-like or irregularly shaped, often with marginal spines, sometimes weakly sclerotized around.
The genus Biston resembles Cusiala Moore and Iulotrichia Warren in: the postmedial lines of both wings often protrudes outwards between M1 and M3; the apex of the uncus is often bifurcated. But Biston differs from Cusiala and Iulotrichia in the following characters: the forewing fovea of the male is absent in Biston but present in Cusiala and Iulotrichia; in the male genitalia, the aedeagus vesica has numerous, very small, spine-like cornuti, arranged as two pair of longitudinal combs in Cusiala and Iulotrichia, which is absent in Biston. The members of Biston also resemble Lycia Hübner, 1825 and Cochisea Barnes & McDunnough, 1916, both of which belong to the former Bistonini. But both of these genera can be distinguished from Biston by the single pair of spurs on the hind tibia, as well as apterous or brachypterous female in Lycia, and absence of the tongue in Cochisea.
Holarctic, Oriental, and Ethiopian regions.
The larva is often twig-like with the characteristic 45 degree resting posture and an obtusely cleft head (

Figs 4–6, 70, 97The external characters of this species are close to those of Biston marginata
as follows: the male antennae are partially bipectinate and filiform at
tip; the forewing postmedial line bilobedly protrudes between M1 and
M3, and slightly protrudes outwards between CuA2 and 1A + 2A. But it
can be distinguished from Biston marginata by the following characters: the hindwing outer margin is concave between M1 and M3, whereas it is evenly round in Biston marginata; the transverse lines are black but dark brown in Biston marginata; the hindwing postmedial line is waved after M3, but straight in Biston marginata;
the transverse lines on the underside of the wings are more
conspicuous. The most distinct differences are in the male genitalia:
the apex of the uncus is broader and bifurcated, whereas it is narrower
and round in Biston marginata; the median process of the gnathos is broader and round terminally, while in Biston marginata,
it is slenderer and acute apically; the setose area of the valva is
much weaker; the juxta is narrower, and sharply pointed apically,
while in Biston marginata, it is broader and round apically; the cornutus is shortly digitiform, but is thornlike in Biston marginata. In the female genitalia (

Figs 7–10, 71, 98, 117The diagnostic characters of external morphology of the species can be seen in the previous species. The male genitalia of the species are close to those of Biston suppressaria. But it can be distinguished from the latter by the following characters: the vesica is less strongly sclerotized posteriorly; the cornutus is small and spine-like but absent in Biston suppressaria. The female genitalia are similar to those of Biston betularia, but they differ in the following characters: the ductus bursae is shorter and the antrum is absent; the corpus bursae is almost even in width, while in Biston betularia it is enlarged, wrinkled and weakly sclerotized posteriorly, narrow medially and swollen anteriorly; the signum is oval with several marginal spines, but a transverse bar in Biston betularia.

Figs 11, 12, 72, 99, 118The external characters of this species are close to those of Biston betularia as follows: the male antennae are partially bipectinate and filiform at apex; the forewing postmedial line protrudes outwards between M1 and M3 and between CuA2 and 1A + 2A; the discal spots of both wings are stripe-like. But it can be distinguished from Biston betularia by the following characters: distinctly smaller; the wing colour is dark brown, but greyish black in Biston betularia; the hindwing basal line is present, but absent in Biston betularia; the forewing R1 and R2 are separate, but stalked in Biston betularia. In the male genitalia, the apex of the uncus and the median process of the gnathos are more slender than those of Biston betularia; the valva is more slender and longer; the juxta is much narrower; the cornutus is small and spine-like, whereas Biston betularia has two kinds of cornuti, one is a large bundle of spines, the other is a small tuft of spines. In the female genitalia, the corpus bursae is curved in the anterior half, while in Biston betularia, it is expanded posteriorly and narrow medially; the signum is elliptic, with several small marginal spines, whereas it is bar-like and without marginal spines in Biston betularia.

Syntypes 1♂, 2♀, China: Kangding. (BMNH)) (Figs 13–16, 73, 100, 119) and Biston betularia nepalensis Inoue, 1982 (Biston betularia nepalensis Inoue, 1982, Bull. Fac. domest. Sci. Otsuma Wom. Univ., 18: 175, figs 40a, b. Holotype ♂, Nepal: Tukcha, near Daulagiri. (BMNH)) (Figs 17–18, 74, 101, 120). In China, the former is widely distributed in the greater part of the country, the latter is distributed in Yunnan and Tibet, and can be distinguished from the former by the weaker transverse lines and the blunter projections of the postmedian lines on both wings.

Figs 19, 20, 75, 102The external characters of this species are close to those of Biston porphyria (Butler, 1889) (India) as follows: the male antennae are bipectinate to tip; greyish brown bands are present basally of the antemedial line of the forewing and distally of the postmedial lines of both wings; the forewing medial line converges with the postmedial line at 1A + 2A; the hindwing postmedial line acutely protrudes between M1 and M3; the submarginal lines of both wings are dark grey. But the species can be distinguished by the following characters: this species (length of forewing: 28–30 mm in male) is larger than Biston porphyria; the wings are broader; the hindwing medial line is more conspicuous. The male genitalia of the species are similar to those of Biston betularia as follows: the apex of the uncus is bifurcated; the median process of the gnathos is about one-half length of the uncus; the juxta is long, narrow, and acute apically. But it can be distinguished from Biston betularia by the longer and narrower valva and the absence of cornuti.

There are two Chinese subspecies of Biston robustum, they are Biston robustum robustum Butler, 1879 and Biston robustum subrobustum Inoue, 1964 (Biston robustum subrobustum Inoue, 1964, Kontyû,
32 (2): 338, pl. 8, fig. 3. Holotype ♂, Taiwan (central): Puli.
(BMNH)). The former is distributed in the mainland China, the latter is
distributed in Taiwan. The description of Biston robustum kiangsua
Wehrli was based on a single, rather aberrant specimen, with a single
printed label “Shanghai China”. Similar forms occur in Japan, as

Figs 21–24, 76, 103, 121Head. Antennae about one-third length of forewing, bipectinate in basal three-fifths, filiform in terminal two-fifths, rami short, length of longest ramus about the same as diameter of antennal shaft; filiform in female. Frons not protruding, smooth-scaled, with basal half white, upper half black. Labial palpus black, small, not extending beyond frons. Vertex white.
Thorax. Dorsum greyish white, scattered with black scales. Patagia and tegulae greyish white, mottled with black scales, pale yellow distally. Posterior margin of metanotum with yellow scales medially. Hind tibia with two pairs of spurs in male, slightly dilated, without hair-pencil. Forewing length: male 32–34 mm; female 42 mm. Forewing outer margin almost straight, hindwing round. Wings white, with pale grey striation. Pattern of forewing: antemedial line black, almost straight anteriorly, distinct, accompanied by a pale yellow band basally; medial line greyish yellow, indistinct; postmedial line black, distinct, acutely protruding outwards between M1 and M3, shallowly protruding outwards between CuA2 and 1A + 2A, sometimes internally dentate on veins; a pale yellow band distally of postmedial line, diffused with black patches; terminal line black; fringe pale yellow mixed with black; discal spot present as pale grey dot, indistinct. Hindwing with basal line black, distinct; medial line only distinct near anal margin; postmedial line black, bluntly protruding outwards between M1 and M3, sometimes appearing as black serrations on veins; a pale yellow band distally of postmedial line; terminal line indistinct; fringe and discal spot similar to those of forewing. Underside white; transverse lines dark grey, similar to those of forewing, discal spot black, heavy, on hindwing smaller than on forewing.
Abdomen. First abdominal segment greyish white with black basal margin, remaining segments yellowish brown, scattered with black dots. Setal patch absent on third sternite of male abdomen.
Male genitalia. Uncus somewhat trapeziform, about three-fifths length of basal width. Gnathos with median process short and broad, round terminally, about two-fifths length of uncus. Valva simple, broad at base, gradually narrowing apically, about twice as long as basal width; costa sclerotized, incurved medially, expanded with particularly dense setae basally. Saccus round, about one-third length of basal width. Juxta short and broad, almost round. Coremata not developed. Aedeagus cylindrical, sclerotized dorsally; vesica scobinate, cornutus shaped as a narrow band.

Corpus bursae long, curved medially, swollen anteriorly, bearing a signum; signum long elliptic with marginal spines.
Diagnosis. The wing pattern of this species is similar to that of Biston contectaria as follows: the forewing outer margin is almost straight anteriorly; the antemedial line is black, broad and almost straight; the postmedial line acutely protrudes between M1 and M3; the medial lines of both wings are greyish yellow and indistinct; pale yellow bands are present basally of the forewing antemedial line and distally of the postmedial line of both wings; the hindwing basal line is black and distinct. But this species is smaller and can be distinguished by the following characters: the postmedial lines of both wings are narrower; the forewing postmedial line weakly protrudes outwards between CuA2 and 1A + 2A, while in Biston contectaria, it is straight; the protrusion between M1 and M3 of the hindwing postmedial line is round but sharply angled in Biston contectaria; the discal spots on the underside of both wings are larger and heavier. In the male genitalia: the much broader uncus and valva of the new species are distinctly different from Biston contectaria. The female genitalia are similar to those of Biston panterinaria as follows: the apophyses posteriores are long; the ostium bursae is sclerotized; the ductus bursae is very short; the corpus bursae is curved medially; the signum is elliptic and narrow. But it can be distinguished from Biston panterinaria by presence of the lamella postvaginalis.

Figs 25, 26, 77, 104The external characters of this species are close to those of Biston suppressaria and Biston inouei Holloway, 1994 (Borneo), but it can be distinguished from those species by the following differences: this species (length of forewing: 27–28 mm in male) is larger than Biston suppressaria and smaller than Biston inouei; the protrusion between M1 and M3 of the forewing postmedial line is relatively acute, but blunt or bilobed in Biston suppressaria and Biston inouei; the hindwing basal line is more distinct in Biston contectaria and Biston inouei; the projection between M1 and M3 of the the hindwing postmedial line is relatively acute in Biston contectaria and Biston suppressaria, but blunt in Biston inouei. In the male genitalia, the apex of the uncus is broader than that of Biston suppressaria and Biston inouei, and is almost not bifurcated; the median process of the gnathos is shorter and round distally, whereas it is longer and pointed in Biston suppressaria and Biston inouei; the costa and the ventral margin of the valva are curved, while those of Biston suppressaria and Biston inouei are less curved or even incurved or concavely curved; the costa is expanded and has dense setae basally, while it is straight in Biston suppressaria and Biston inouei; the juxta is shorter and less pointed apically.

Figs 27–30, 78, 105, 122The external characters of this species are close to those of Biston contectaria, but it can be distinguished from that species by the following differences: the wings are pale yellow but white in Biston contectaria; the forewing postmedial line is much narrower and protruding outwards between CuA2 and 1A + 2A, while in Biston contectaria, it is broader and without such a protrusion; the discal spot on the hindwing upperside is large, round, black, while in Biston contectaria it is almost absent; the discal spots on the underside of both wings are larger and heavier. The male genitalia are close to those of Biston suppressaria, but it can be distinguished by the square apex of the juxta, the shorter median process of the gnathos and the presence of a cornutus which is a short spinous patch. The female genitalia are similar to those of Biston suppressaria. But it differs in that the corpus bursae is coiled anteriorly; the signum is longer and narrower; the ostium bursae is more strongly sclerotized.

Biston luculentus Inoue, 1992, described from SE. Thailand, is similar to Biston suppressaria benescripta, but has the transverse lines even more clearly expressed (e.g. see fig. 37 which is almost identical with Biston luculentus). Like Biston suppressaria benescripta, also the Biston luculentus form occurs sympatrically with typical Biston suppressaria suppressaria or with Biston suppressaria benesparsa Wehrli, the latter being a rather rare form, at many places. Also at the type locality of Biston luculentus (Prov. Chanthaburi, Khao Soi Dao) it occurs together with typical suppressaria (coll. ZFMK) Comparison of the genitalia of the two revealed no differences. Thus we follow Stüning (in litt.) and synonymize Biston luculentus with Biston suppressaria. Besides, we also believe that the strange, almost patternless female figured by
http://species-id.net/wiki/Biston_regalis
Figs 41, 42, 81, 108, 124The wing pattern of this species is similar to that of Biston exalbescens Inoue, 2000 (Philippines) as follows: the forewing postmedial line is weakly waved, broadly protruding outwards between R5 and M3 and below CuA2; the hindwing outer margin is concave between M1 and M3; the hindwing postmedial line protrudes outwards between M1 and M3; dark brown bands are present basally of the forewing antemedial line and distally of the postmedial line of both wings, and usually absent at apical area and between M3 and CuA1 of the forewing. But the species can be distinguished from Biston exalbescens by the following characters: the forewing antemedial line is thinner, the dark brown band basally of it is narrower; the medial lines of both wings are less conspicuous. In the male genitalia, it differs in the much stronger central setose area of the valva; the median process of the gnathos is spatulate terminally, but pointed in Biston exalbescens; the juxta is longer and narrower; the vesica with two cornuti, a basal, oval plate with a lateral tooth and an elongate, sclerotized, spined fold. The female genitalia of this species are close to that of Biston betularia, but it has a nearly triangular lamella postvaginalis, which is absent in Biston betularia; the ductus bursae is broader and sclerotized, without antrum; the corpus bursae is pouched, but enlarged posteriorly and narrow medially in Biston betularia; the signum is almost oval, but bar-like in Biston betularia.

http://species-id.net/wiki/Biston_quercii
Figs 44, 45, 83, 110The wing pattern of this species is similar to that of Biston falcata as follows: the forewing antemedial line is black, slightly waved; the postmedial lines of both wings are black and dentate; broad brown bands are present basally of the forewing antemedial line and distally of the postmedial lines of both wings; the speckles scattered on the wings are black, and often gather to a black patch basally of the submarginal lines; the hindwing medial line is black and double. But it can be distinguished by the following characters: the outer margins are more undulating, there are distinct marginal processes in the centre of both wings, absent in Biston falcata; the hindwing discal spot is present. The male genitalia are similar to those of Biston falcata as follows: the apex of the uncus is round; the median process of the gnathos is broad and round apically; the juxta is long, narrow, acute and with a longitudinal arris apico-ventrally; the cornutus is shaped as a spinous patch. But this species is characterized by the narrower juxta and the longer spines of the cornutus.

After examinating the types of Amphidasis erilda Oberthür, 1910, Amphidasis clorinda Oberthür, 1910, Biston emarginaria Leech, 1897, Biston erilda satura Wehrli, 1941 and a large series of material from China and the neighbouring regions it became obvious that Biston emarginaria (only females known) and Amphidasis clorinda (female holotype known only) are all females of Amphidasis erilda. The external and genital features of Amphidasis erilda, on the other hand, turned out to be almost identical or fall within the range of variation of Biston falcata. Thus we treat Biston emarginaria, Amphidasis erilda, Amphidasis clorinda as junior synonyms of Biston falcata. Biston erilda satura, as described by
http://species-id.net/wiki/Biston_perclara
Fig. 54The external characters of this species are similar to those of Biston thibetaria as follows: the forewing antemedial line and the postmedial lines of both wings are black and thick; black patches are present distally of the forewing postmedial line between M1 and M3, reaching the outer margin; another smaller black patch is present distally of the forewing postmedial line below M3. But in this species the broad bands placed basally of the antemedial line of the forewing and distally of the postmedial lines of both wings are pale yellow and indistinct, whereas they are yellowish green and distinct in Biston thibetaria; the discal spots of both wings are less distinct or have completely vanished; the forewing postmedial line is straight between CuA2 and 1A + 2A, while it is slightly excurved in Biston thibetaria. The male genitalia of the species are almost identical to those of Biston thibetaria. But the median process of the gnathos of the species is truncate apically and the incision of posterior margin of the juxta is less deep.

http://species-id.net/wiki/Biston_thibetaria
Figs 55-57, 89, 114, 128This species is very distinct and is easily recognizable by the thick black lines and yellowish green bands placed basally of the antemedial line of the forewing and distally of the postmedial lines of both wings, the large, black ringed and pale-centred discal spots on both wings, as well as the black-belted abdomen and the fresh yellow anal tuft. The male genitalia of Biston thibetaria are close to those of Biston panterinaria: the apex of the uncus is bifurcated and about four-fifths as long as the basal width; the median process of the gnathos is short and round apically; the valva is broad basally and narrow apically; the ventral margin of the valva is slightly sinuous; the juxta has a deep incision at the middle on the posterior margin; the cornutus is stick-like; a narrow sclerotized band is present on lateral side of the aedeagus. But it can be distinguished from that species by the strongly rounded basal half of the valva. The female genitalia of the species are close to those of Biston panterinaria as follows: the ostium bursae is weakly sclerotized; the ductus bursae is very short; the corpus bursae is curved medially, striated in the posterior half and enlarged at tip; the signum is oval and with marginal spines. It differs in having an oval lamella postvaginalis, which is absent in Biston panterinaria.
