Diagnosis.
Antennae massive, gradually thickened distally (
Fig. 63
); aedeagus (
Figs. 72–73
) stout with short lateral groups of needle-like internal sclerites.
Redescription.
Body of male (
Fig. 63
) strongly convex, elongate and slender, with long appendages, BL
1.80 mm
; glossy, uniformly reddish-brown with slightly lighter appendages; vestiture yellowish.
Head (
Figs. 63
,
69
) approximately subtriangular, broadest at eyes, HL
0.33 mm
, HW
0.33 mm
; tempora much shorter than eyes; vertex distinctly transverse and weakly, evenly convex, anteriorly confluent with frons; frons convex, just behind barely marked supraantennal tubercles with a pair of shallow circular impressions; eyes large and strongly convex, strongly oval and oblique in relation to the long axis of the head. Punctures on head dorsum fine and sparse, inconspicuous; setae short, sparse, suberect. Antennae (
Fig. 63
) robust, gradually thickened distally, AnL
0.95 mm
; antennomeres I–III strongly elongate, IV as long as broad, V–VI slightly longer than broad, VII–X each slightly transverse, XI 1.5
×
as long as broad.
Pronotum (
Fig. 63
) in dorsal view with large and subtriangular discal part broadest near anterior fourth of PL and short posterior collar demarcated by distinct lateral constriction, PL
0.48 mm
, PW
0.39 mm
; anterior and lateral margins of discal part confluent and rounded; posterior margin arcuate; hind pronotal corners indistinctly marked, blunt and obtuse; posterior collar dorsally indistinctly demarcated by shallow, narrow and arcuate transverse groove with deepened lateral parts running on pronotal sides and connecting very small and indistinct lateral ante-basal foveae located on sides of pronotum, groove extends at each end beyond lateral foveae nearly to adcoxal part of hypomeron; posterior collar in middle bearing indistinct and short median longitudinal ante-basal groove. Punctures on pronotal disc very fine and inconspicuous; setae long, sparse and recumbent to suberect.
Elytra (
Fig. 63
) oval and more convex than pronotum, broadest between middle and anterior third, EL 1.00 mm, EW
0.70 mm
, EI 1.43; humeral calli distinct, developed as elongate protuberances; elytral apices separately rounded. Punctures on elytral disc more distinct than those on pronotum but shallow and sparse; setae moderately long, sparse and suberect.
Hind
wings well-developed, twice as long as elytra.
Legs (
Fig. 63
) long and slender; all tibiae straight or nearly straight.
Aedeagus (
Figs. 72–73
) stout, AeL
0.38 mm
, median lobe subtrapezoidal, with abruptly and strongly narrowed apical part of dorsal wall forming long subtriangular projection; internal armature complicated, composed of submedially located central complex and sub-apical lateral groups of short needle-like sclerites projecting distally from median lobe; parameres slender, each with two long apical setae.
Female.
Unknown.
