Diagnosis
2.35−2.6 mm long (mean = 2.46 mm; n = 4); 3.0−3.33 times as long as wide. This species is distinguished by the elytralelytral:
pertaining to the elytra
apexapex:
point or edge furthest from the body; opposite of base
acuminateacuminate:
tapering to a long point
; two mycangial pits broad and narrow on basalbase:
point or edge closest to the body; opposite of apex
slope of elytra; declivitaldeclivital:
pertaining to the elytral declivity
interstriae denticulatedenticulate:
covered in denticles
; and antennalantennal:
pertaining to the antennae
funicle 4-segmented.
This species most closely resembles C. turbineus and can be distinguished by the smaller size and by the elytralelytral:
pertaining to the elytra
vestiture uniseriate on all discaldiscal:
pertaining to the disc of either the pronotum or elytra
interstriae (except at basebase:
