Type material.
Holotype ♂ (ZIN): "Vietnam N, (Sa Pa), Lao Cai prov., 250km from Hanoi bearing 310#, Sa Pa vill. env., Hoang Lien Son Nat. Res., 1250-1300m, 15.-21.6.1998, leg. A. Napolov".
Distribution.
Vietnam (Sa Pa).
Description.
Male (Fig. 5). Body black, mandibles dark brown, pronotum red, with a large black marking in center of disc, elytra red, nearly black at the whole length of the first and second elytral interstices.
Head evenly narrowed behind eyes, surface densely and finely punctate, semilustrous, covered with dense, fine, yellowish brown decumbent pubescence; eyes strongly protruding, head width across eyes distinctly wider than anterior margin of pronotum; terminal maxillary palpomere long-triangular, nearly truncate and sharp at apical one-third length of inner margin; antennae (Fig. 13) almost extending to apical one-fourth length of elytra, antennomeres II nearly as long as wide at apices, III–XI flattened, III–IX obliquely widened apically, nearly long-triangular, III about twice as long as wide at apices, IV slightly longer than III, X–XI nearly parallel-sided, XI slightly longer than X and pointed at apices, IV–XI each with a short narrow longitudinal smooth impression at apical part of outer margin.
Pronotum distinctly longer than wide, widest near posterior margin, anterior margin rounded, anterior angles rounded, lateral margins moderately diverging posteriorly, slightly sinuate at anterior portion, posterior angles rectangular, posterior margin slightly arcuate and narrowly bordered, disc moderately convex at posterolateral parts, surface punctate and pubescent like that of head, semilustrous.
Elytra about 5.3 times longer than pronotum, 4.0 times longer than humeral width, which about one-third wider than posterior margin of pronotum, lateral margins nearly parallel, elytral venations moderately developed, slightly costate.
All tarsal claws simple.
Abdominal sternite IX long-triangular. Aedeagus (Figs 28-30): ventral process of each paramere flattened, twist in middle and tapered at apex in ventral view, slightly narrowed at base and distinctly bent dorsally in lateral view; dorsal fig slightly shorter than ventral process, abruptly narrowed at inner apical portion, with a longitudinal ridge in middle of basal portion, membranous between inner margin and the ridge, inner angle rectangular, outer angle acute-angled and bent ventrally, inner margin distinctly protuberant in middle, apical margin nearly straight, around with long pubescence; laterophyse with apex pointed laterally to outer apical angle of dorsal fig.
Female. Unknown.
Body length (male): 9.0 mm; width: 1.5 mm.
Etymology.
Patronymic, dedicated to its collector, Alexander Napolov (Riga, Latvia).
Diagnosis.
This species could be easily distinguished from others by its aedeagus: ventral process of each paramere slightly flattened and twist in middle in ventral view, distinctly bent dorsally in lateral view, dorsal fig with a longitudinal ridge in middle of basal portion, membranous between inner margin and the ridge.
Remarks.
The left mesoleg and right metatarsomeres II–V of the holotype are missing.
