Diagnosis

4.3−4.9 mm long (mean = 4.5 mm; n = 5); 1.88−1.96 times as long as wide. This species can be distinguished by the mesonotal mycangial tuftmycangial tuft:
tuft of setae that denotes the mycangia exterior opening
the length of the scutellumscutellum:
a shield-like sclerotized plate located at the midpoint of the elytral base 
; elytralelytral:
pertaining to the elytra
discdisc:
the flat central upper surface of any body part (e.g. pronotum and elytra)
convexconvex:
appearing rounded
; declivitydeclivity:
downward slope of either the pronotum or elytra
obliquely truncatetruncate:
appearing cut off or suddenly shortened
with laterallateral:
pertaining to the side
margins obliquely costate; declivitydeclivity:
downward slope of either the pronotum or elytra
opalescent and unarmed; declivitaldeclivital:
pertaining to the elytral declivity
striae not impressedimpressed:
a depression in a surface
; body stout and densely covered by erecterect:
pertaining to setae that have their apices directed away from the body and appear straight
dark brown pubescencepubescence:
fine short setae
.

Similar to Cnestus mutilatus and Hadrodemius species but scutellumscutellum:
a shield-like sclerotized plate located at the midpoint of the elytral base 
visible, declivitydeclivity:
downward slope of either the pronotum or elytra
less steeply truncatetruncate:
appearing cut off or suddenly shortened
, posterolateralposterolateral:
relating to end of the side part/portion
carinaecarina:
an elevated ridge or keel, not necessarily high or acute
absent, procoxae contiguous, and the mesonotal mycangial tuftmycangial tuft:
