Hovorka, 2019: 31 (Tam Dao, Vietnam).

MATERIAL. Eight specimens from Tam Dao, Vinh Phuc Province, Vietnam : ♀ ( MSPU), VII.1997 (A. Ryabov ) ; ♂, ♀ ( MSPU), h~ 900 m, 10.VII.1990 (unknown collector) ; ♂, 4♀♀ ( ZISP), 20. V. or 25. V., or 8. VI.1995 (A. V. Gorokhov ). — Aedeagus with everted and inflated internal sac examined in male .

DIAGNOSIS. An apterous black species, distinctive in having the body larger-sized, the aedeagus distinctive, both the head and the genae long, no or indistinct impression on vertex, the elytral ridges equally developed and sparsely pubescent, with setae arranged in a single row on each side.

REDESCRIPTION. Unnecessary except some characters only. BL 25.9–27.3 mm (26–28.1 mm in the type series). Body ( Fig. 19 ) black, diverging reddish spots on vertex indistinct, traceable in teneral specimens only. Antennal scape brown black, with extreme base slightly reddish, antennomeres 2–11 reddish-brown. Microsculpture superficial, distinct over pronotum and on basal 1/2 head, nearly obliterate before; punctation rather fine and confluent or almost so on both pronotum and basal 1/2 head, head otherwise nearly smooth and glabrous.

Head long, a fourth to a third longer than wide, smooth frontal carina short, subcostate before, almost flat behind.

Pronotum nearly parallel-sided in front of to distinctly diverging to base; basal angles slightly acute to almost right, more or less blunted. Base truncate and indistinctly trisinuate, apex slightly sinuate and straight at middle. Disc moderately convex; median line fine, slightly impressed, obliterate before and behind. Basolateral foveae and sublateral lines shallow, separate at middle or nearly so.

Elytral apices obliquely truncate, angulate combined, slightly sinuate inside outer angles; sutural angles acute and distinctly pointed to blunt. Pubescence sparse, forming single row on each side of ridge and a doubled row on each side of even intervals in basal fifth only; setae becoming gradually denser basad from two to four outside basal 3/5 ridge 8.

Aedeagus ( Figs 60 , 102–104 ): left paramere oviform, with both dorsal and ventral margins rounded toward a moderately rounded apex. Internal sac with three laterobasal bulbs, single right and two left, eight dorsomedial and three left lateral sclerites; basalmost of these latter being long, curved, situated at apex of right laterobasal bulb.

DISTRIBUTION. Known from the type locality only. A male paratype from Phan Xi Pang Mt. may have incorrect data label or belong to a different species.

NAME. Refers to the underdeveloped fasciated elytral pattern.

HABITATS AND HABITS. From analogy with the other species from Vietnam, this species is forest-dwelling.
