Description.
Habitus elongate, fusiform. Body colouring black, rarely dark brown. Pale part of setation consists of recumbent yellowish or greyish setae forming rather indistinct ocellations on pronotum, elytra and abdominal sternites (
Fig. 2
).
Measurements. Males:
20–24 mm
; female:
25 mm
.
Head punctation consists of sparse moderately large setigerous punctures. Antenna long, slender, last antennomere almost rectangular, with apical elongation of variable length, ca. 3.60–4.64 times as long as wide (
Fig. 26
), its ventral side smooth.
Pronotum trapezoidal, ca. 1.85–1.95 times as wide as long. Sides of rather variable shape; in some specimens almost regularly rounded (
Fig. 46
). On the other hand some specimens have sides skewed and straight in anterior half, subparallel in basal half, with an indistinct obtuse angle present near the middle. Disc with two oval shallow depressions. Punctation consists of sparse moderately coarse setigerous punctures on the disc, which become slightly coarser and denser laterally.
Elytra with numerous longitudinal rows of moderately large punctures, and fine interstitial setigerous punctures.
Ventral part with fine punctures, which are sparse medially and become larger and denser laterally. Last abdominal ventrite laterally regularly rounded to apex.
Male. Aedeagus with phallobase slightly shorter than parameres. Parameres simple, relatively broad. Subbasal parameral hook small, but the subapical hook is well developed and prominent. Median lobe narrowly lanceolate (
Fig. 66
).
Female. Similar to male in habitus, but larger. Antenna shorter, and more slender.
Distribution.
Known from several localities in southern and south-eastern
China
(Fujian, Guizhou, Hubei, Hunan).
