Platyscelis
( Figs. 4, 25–26, 57–58)
Diagnosis.This new species is similar to Platyscelis( Platyscelis) gebieni Schuster, 1915, but can be distinguished from the latter by the following characters: (1) punctures dense and fine on head (extremely dense and moderately coarse in P. gebieni); (2) pronotum with unconnected oval dense and fine punctures at sides (dense and coarse and merged partially in P. gebieni); (3) parameres narrow and long, dorsal side straight in lateral view (obviously wide, apex curved to dorsal side occasionally in P. gebieni).
Description.Body black with weakly shining, tarsus, antennae and palpus weak brown. Male( Figs. 4, 25–26, 57). Anterior margin of frontoclypeus straight, surface with dense and fine punctures. Frons and genae weakly convex, with punctures dense and fine. Eyes transverse, with shallowly emarginate anterior margin. Antennae ( Fig. 4: B) almost reaching base of pronotum, 2nd to 8th antennomeres cylindrical and thicker at apex, 9th to 10th almost spherical, and 11th sharped-oval. Length (width) ratio of 2nd to 11th antennal segments 29 (16): 76 (19): 41 (18): 40 (18): 38 (18): 39 (19): 39 (22): 33 (22): 33 (26): 43 (27). FIGURES 57–62.Habitus. 57–58. Platyscelis helanensis(57. male, holotype; 58. female, paratype); 59–60. P. licenti(males, 59. lectotype); 61. P. subcordata(male); 62. P. suiyuana(male, paralectotype). Pronotum ( Fig. 4: A) transverse and convex, widest at base, 1.5 times as wide as long, 2.1 times as wide as head. Lateral margins nearly parallel from base to middle and arcuately narrowing toward apex. Ratio of width at anterior margin to basal 25: 49. Anterior margin nearly straight and posterior one straight. Anterior angles obtuse and posterior ones rectangular. Lateral margins edged in anterior margin and posterior one not edged, entire lateral margins edged, widely depressed from base to middle. Punctures fine and dense on disc, unconnected and oval at sides. Prothoracic hypomera with coarse wrinkles and sparse yellow setae. Prosternum before procoxae with yellow setae, prosternal process projecting beyond level of procoxae, weak sharp at apex in lateral view. Mesoventrite with punctures and yellow setae. Elytra oval and weak convex, base moderately wider than pronotum and widest at middle, 1.2 times as long as wide and 1.2 times as wide as pronotum. Surface rough, with shallowly dense and coarse punctures, while smaller and blurred at apex, and weak longitudinal carinae or traces. Lateral carina visible nearly completely in dorsal view and almost reaching sutural angle. Abdomen with short sparse yellow setae, not depressed at middle of 1st and 2nd ventrites. Profemora with sparse punctures and yellow setae. Protibiae ( Fig. 4: D) gradually widened towards apex and curved at inner side, underside concave at apex and apical margin foliate extended, inner side with dense yellow hairbrush at apex. Protarsi ( Fig. 4: C) strongly widened but narrower than apex of protibiae. Meso- and metafemora longer than profemora. Mesotibiae ( Fig. 4: E) gradually widened toward apex with rufous strong setae. Mesotarsi ( Fig. 4: F) moderately widened and narrower than apex of mesotibiae. Metatibiae ( Fig. 4: G) straight, with rufous strong setae. Length (width) ratio of pro-, meso- and metafemora 27 (10): 30 (8): 38 (9), that of corresponding tibiae 25 (9): 26 (6): 34 (6), and protarsi 22 (28): 50 (71): 30 (63): 13 (33): 54 (23), mesotarsi 31 (35): 51 (57): 30 (41): 20 (29): 71 (24), metatarsi ( Fig. 4: H) 109 (29): 57 (28): 39 (25): 82 (24). Aedeagus ( Figs. 4: I–K, 25–26) 3.5 mmlong and 0.9 mmwide. Parameres 1.0 mm long and 0.6 mmwide, narrow and long, widest at base and narrowing toward apex, outer margins with sharp hooks at apex, dorsal side straight in lateral view. Female( Fig. 58). Body wider, antennae not reaching base of pronotum, pro- and mesotarsi not widened, other characters similar to male. Measurements.Body length: ♂ 10.9–12.1 mm, ♀11.0– 11.6 mmand width: ♂ 5.7–6.3 mm, ♀ 5.9–6.5 mm.
