Diagnosis

This species is the largest member of the genus. Moreover it can be distinguished by its antenna length exceeding width of the head with antennomeres 4–8 elongate.

Description

Length 8.1–9.0 mm; TL / EW = 1.21–1.25; PL / PW = 0.42–0.48; EL / EW = 1.08; EW / PW = 1.91–2.03.

Body ( Figures 11H , 15D ) heart-shaped, convex; surfaces distinctly setose with white, short, appressed pubescence; black with only mouthparts brown (except for two last maxillary palpomeres) and antennomeres 2–8 yellowish.

Antenna ( Figure 11A ) longer than width of the head; antennomere 3 longer than pedicel and slightly shorter than antennomeres 4 and 5 combined; antennomeres 4–8 elongate, twice as long as wide, subequal in length to each other. Mandibles with lower apical tooth large, subtriangular, upper one reduced, both subapical teeth large, subtriangular; all teeth without additional serration ( Figure 11C, D ); ventral surface of subapical teeth distinctly tuberculate. Labrum weakly emarginate medially at apex ( Figure 11B ). Labium ( Figure 11G ) with palpomere 1 small, subquadrate, about half the length of second palpomere; terminal palpomere long, about 1.8 times longer than palpomere 2. Terminal maxillary palpomere somewhat securiform about 1.2 times longer than wide ( Figure 11F ).

Prosternal process ( Figure 11J ) truncate at apex, with sides subparallel; width of prosternal process about 1.35 times greater than length of prosternum in front of procoxae. Mesoventral process about 0.7 times as wide as coxal diameter at the same position ( Figure 11I ).

Legs with hind femora protruding from outer margin of elytral epipleuron ( Figure 11H ).

Abdominal postcoxal lines regularly curved, distinctly incomplete ( Figure 12A, H ); male ventrite 5 apical broadly and deeply emarginate ( Figure 12H ), ventrite 6 narrowly and deeply emarginate ( Figure 12I ), tergite VIII large, highly sclerotized, rounded ( Figure 12J ); apical margin of female ventrite 5 truncate ( Figure 12A ), sternite and tergite VIII rounded ( Figure 12D, E ).

Male terminalia and genitalia ( Figure 12F, G, K–N ). Tergite IX not divided dorsally. Tergite X deeply emarginate at anterior margin. Penis guide as long as parameres, strongly curved outwardly towards apex. Parameres weakly widening apically. Penis long, S-shape; apex pointed.

Female genitalia an in Figure 12B, C with coxites transverse, almond-like; their outer lateral margins fused with paraprocts.
