Redescription.
Body brown to dark testaceous. Head pitchy, pronotum brown with dark posterior and lateral margins. Abdomen brownish. Length [average] male, 5.0 mm; female,
4.7 mm
.
Male
. Head (
Fig. 5A
) far broader than long, widest at eyes. Disc sparsely punctate, less pubescent. Clypeus trapezoidal and not protruding, almost 1/3 head length, weakly depressed in anterior part (lower than anterior margin), surface impunctate and coriaceous; anterior margin truncate. Supra-antennal ridges moderately elevated upward. Epistomal suture, lateral portions running posterolaterally curved medially after posterior 1/3. Vertex almost flat, definitely distinguished from neck by middle portion of occipital suture; with mid-longitudinal suture distinct. Eyes with coarse facets, strongly convex and protruding laterally, twice or more longer than temples. Temples broadly rounded at posterolateral angles. Occipital suture arcuate in dorsal view; nuchal ridge present and visible in middle, dorsal basal ridge present.
Mandible (
Fig. 5C
) stout, slightly curved; two denticles on inner edge near middle. Antenna (
type
I) a little shorter than or equal to head and pronotum together, with apical antennomere longer than preceding one.
Pronotum transverse, broadest at near anterior 1/3, slightly wider than or equal to head. Disc 3-sulcate (as
Fig. 1H
), but with two paramedial sulci and two paralateral depressions shallow; lateral margin even in front, crenulate behind, posterolateral angles rounded. Elytra (
Fig. 1J
) punctate and rugose, and with lateral longitudinal ridge present.
Abdomen coriaceous and pubescent, broadest at segment IV or V. Sternite VII (
Fig. 5E
) with posterior margin shortly produced in middle and weakly emarginate at apex. Sternite VIII (
Fig. 5F
) broad, with subbasal ridge continuous in middle, with two deeply V-shaped ruptures near middle, forming large and subrectangular median plate, apical margin of median plate straight but a little produced in middle, in center of median plate with small tubercle, with seta at each posterolateral corner, with mid-longitudinal internal ridge on inside surface. Tergite X (
Fig. 5H
) longer than wide, posterior margin truncate with a little notch in middle, posterior margin with two lines of setae on haired posterior part.
Aedeagus (
Figs. 5K–M
). Median lobe oblong-ovoid, widest at middle; with membranous structures inside apical part of median lobe; apical orifice large; apico-medial hook flattened C-shaped in lateral view and bent at near middle, with apical tip pointed, basal process well developed and with round tip; dorsal membranous area not covering all dorsum but across length of median lobe. Paramere arm-like, with seta on apical 1/3 of apical arm and with highlighted zone nearby; apex pointed; with shallow furrow on basal arm.
Female
. Head (
Fig. 5B
) smaller than male. Eyes convex and protruding laterally beyond temples, temples almost invisible in lateral view. Mandible (
Fig. 5D
) as long as in male but slenderer and shaper at apex.
