This species was omitted from the Palaearctic Catalogue by Kazantsev and Brancucci (2007). Both the aedeagus and female internal genitalia of this species have been well illustrated by Okushima (2005).

Male. Aedeagus: basal piece nearly as long as dorsal plate of each paramere (Fig. 3A–C); ventral process of each paramere stout and abruptly narrowed near apex, obviously bent inwards in ventral view (Fig. 3A), slightly bent dorsally in lateral view (Fig. 3C); dorsal plates of parameres obviously longer than ventral processes, with lateral margins slightly sinuate in middle, apical margins slightly arcuate and descending outwards in lateral view (Fig. 3B); laterophyse feebly shorter than ventral process, with apex acute and directing dorso-outwards (Fig. 3A); inner sac of median lobe with a stout tube extruding near base (Fig. 3A, B).

Female. Internal organ of reproductive system (Fig. 12C): spermatheca nearly as long as diverticulum; accessory gland ~ 2.5× longer than spermatheca.

Abdominal sternite VIII (Fig. 16C): triangular emarginations on both sides and in middle of posterior margin, lateral emarginations slightly deeper and much wider than the middle one, the portions between lateral and middle emarginations wide and obtuse-triangular at apices, slightly extending over apices of latero-apical angles, which are nearly truncated.

Cantharis jeanvoinei Pic, 1927 was listed as a synonym of L. guerryi by Kazantsev and Brancucci (2007), which is an obvious error. In fact, the former was synonymized with L. guerryi atroapicipennis (Pic, 1914) by Wittmer (1995), but was missing in the Palaearctic Catalogue (Kazantsev and Brancucci 2007).

China (new record: Yunnan); Vietnam.

The aedeagus of this subspecies is very similar to that of L. guerryi guerryi, but its elytra are darkened at apices enabling external identification. The body coloration is constant, and the elytra of the individuals from northern Yunnan are uniformly pale yellow (L. guerryi guerryi), while those from southern Yunnan and adjacent area (northern Vietnam) are always darkened at apices (L. guerryi atroapicipennis), so they are kept as two subspecies at the moment. Here, L. guerryi atroapicipennis is recorded in the Chinese fauna for the first time.

Also, its aedeagus is unique and differs from all others in the ventral process of each paramere expanded near base in lateral view (Fig. 8C), and broad laterophyse in ventral view (Fig. 8A).

Figure 8. 

Aedeagus A–C Lycocerus laterophysus sp. nov. D–F L. flavipennis sp. nov. A, D ventral view B, E dorsal view C, F lateral view. Scale bars: 1.0 mm.

Male (Fig. 18A). Head, prothorax and legs orange, vertex black, mandibles dark brown, antennomeres III–XI black, pronotum with a wide black longitudinal median band extending from posterior to anterior margins, scutellum black, elytra pale yellow, tarsi darkened, meso- and metasterna and abdomen black. Body densely covered with yellow recumbent pubescence.

Head feebly narrowed behind eyes, surface densely and finely punctate; eyes moderately large and protruding, head width across eyes feebly wider than anterior margin of pronotum; antennae filiform, extending to elytral mid-length when reclined, antennomere II shortest, ~ 2.5× longer than wide at apex, III–V feebly widened apically, IV–X each with a short smooth impression near apical part of outer margin, V longest, VI–XI nearly parallel-sided, XI acute at apex.

Pronotum distinctly longer than wide, anterior margin feebly arcuate, lateral margins subparallel, posterior margin nearly straight, anterior angles rounded, posterior angles right-angled, disc convex on posterolateral parts, surface finely and feebly sparsely punctate than that on head.

Elytra ~ 4.5× longer than pronotum, 5.4× longer than width across humeri, outer margins nearly parallel, disc semi-lustrous, coarsely and densely punctate.

Legs slender, all tarsal claws simple.

Aedeagus: basal piece nearly as long as dorsal plate of each paramere (Fig. 8A–C); ventral process of each paramere slender, feebly bent inwards and approaching each other in ventral view (Fig. 8A), slightly expanded near base and bent ventrally in lateral view (Fig. 8C); dorsal plates of parameres obviously longer than ventral process (Fig. 8A, C), with apical margins arcuate and descending inwards in dorsal view (Fig. 8B); laterophyse nearly as long as ventral process and broad in ventral view, with apices acute and directing dorso-outwards (Fig. 8A, C).

Female (Fig. 18B). Similar to the males, but eyes less protruding, antennae thinner and shorter, extending to basal one-third length of elytra when reclined, middle antennomeres without impressions, fore and middle legs with a digitiform tooth on each anterior claw, pronotum feebly longer than wide.

Internal organ of reproductive system (Fig. 14D): spermatheca feebly shorter than diverticulum; accessory gland ~ 2.5× longer than spermatheca.

Abdominal sternite VIII (Fig. 16H): hardly emarginate in middle and subtriangular emarginations on both sides of posterior margin, lateral emarginations obviously deeper than the middle one, the portion between lateral and middle emarginations wide and rounded at apices, obviously extending over apices of latero-apical angles, which are subrounded.

Body length: 9.3–9.7 mm (9.3 mm in holotype); width: 1.8–2.0 mm (1.8 mm in holotype).

China (Guangxi).

The new species is named after the quite wide laterophyse of its aedeagus.

Holotype : ♂ (MHBU), China, Zhejiang, Lin’an, Qingliangfeng, 16–22.V.2012, leg. G. L. Xie. Paratypes: China: 2♀ (MHBU), same data as holotype; 1♀ (MHBU), Zhejiang, Lin’an, Qingliangfeng, Shunxiwu, 15–18.V.2012, leg. J. S. Xu & L. X. Chang; 1♀ (MHBU), Zhejiang, Lin’an, Qingliangfeng, Longtangshan, 19.V.2011, leg. G. L. Xie.

The new species resembles L. pictipennis in the coloration and characteristics of tarsal claws, but differs from the latter in the aedeagus: basal piece very large, ~ 3× longer than dorsal plate of each paramere in lateral view (Fig. 8F), dorsal plate narrow (Fig. 8E), laterophyse slightly bent inwards in ventral view (Fig. 8D). In comparison, in the aedeagus of L. pictipennis, basal piece is nearly as long as dorsal plate of each paramere in lateral view (Fig. 7F), dorsal plate wide (Fig. 7E), laterophyse obviously bent outwards in ventral view (Fig. 7D).

Also, it is similar to L. kubani in the structure of tarsal claws, genitalia of both sexes and female abdominal sternite VIII, but which are different in each component part in detail, and can be easily distinguished from the latter in the uniformly yellow elytra, while elytra black at apices in L. kubani. The coloration of elytra is stable and a good character to recognize the species in L. pallidulus group.

Male (Fig. 18C). Head, prothorax and legs yellowish orange, mandibles dark brown at apices, antennomeres III–XI black, scutellum orange and darkened along margins, elytra pale yellow, tibiae and tarsi black, except for protibiae yellow ventrally, meso- and metasterna and abdomen yellowish brown. Body densely covered with yellow recumbent pubescence.
