Mesonotum with 1 long notopleural, 1 similar postalar and 4 scutellars (lateral pair very short, apical pair somewhat longer than notopleural seta, subparallel); acrostichals lacking; dorsocentrals uniserial, mostly minute, in holotype prescutellar pair obscured by pin (in paratype prescutellars very short, nearly as long as lateral scutellars); mesosternum
and metasternum bare between posterior four coxae.
, metapleurae and metasternum lacking granulation.
Head: wider than long, shorter than maximum length of pronotum; labium reaching posterior border of mesosternum
; interocellar distance shorter than 0.50; antenniferous tubercle exposed, elongate, armed with long spine, directed forward, not convoluted, reaching basal third of antennal segment I.

truncate or slightly emarginate at apex.
and metasternum with sparse and inconspicuous small granules.
2B, D); labium slightly surpassing posterior margin of prosternum, but not reaching middle of mesosternum
relatively narrow between coxae, quadrate, a little wider than long.
Mesonotum is brownish with margins and carinae shaded with black; mesoscutellum dark brown and medially whitish; yellowish brown mesopleuron and sternum, yellowish membranes; dark brown markings present on carinae around mesocoxal cavity and on median zone of mesosternum
. Brownish metathorax, ventrally paler with a mediolongitudinal grayish line.
Pectoral canal on prosternum open behind and passing anterior margin of mesocoxae, rostrum not touching middle coxa, but ending in receptacle on mesosternum
, mesosternal process cavernous, forming receptacle, receptacle at least as long as wide, its inner margin U-shaped; mesosternum
truncate between middle coxae, width of mesosternum
separating middle coxae wider than the dorsal apex of the rostrum (Fig.
set with a few white granules, metasternum smooth.
1B), 1.4 times length of pronotum; antennal segments II and III moderately long and somewhat thickened; labium usually only reaching the apex of mesosternum
, sometimes extending just beyond base of middle coxa; hind tibia with short reclining pale setae.
