2.95−3.1 mm long (mean = 3.02 mm; n = 2); 2.81−3.1 times as long as wide. This species can be distinguished by the elytralelytral:
pertaining to the elytra
declivitaldeclivital:
pertaining to the elytral declivity
slope gentle, gradual; separation between the smooth, shiningshining:
appearing glossy or bright in luster; referring to a surface that is polished and reflects light well
elytralelytral:
pertaining to the elytra
discdisc:
the flat central upper surface of any body part (e.g. pronotum and elytra)
and shagreenedshagreened:
covered with a closely-set roughness, like shark skin
declivitydeclivity:
downward slope of either the pronotum or elytra
gradual, not sharply distinct; declivitaldeclivital:
pertaining to the elytral declivity
striae weakly impressedimpressed:
a depression in a surface
, punctures large, distinct; declivitaldeclivital:
pertaining to the elytral declivity
interstriae tuberculate with three large equally spaced tuberclestubercle:
a small knob-like or rounded protuberance of the exoskeleton
along interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
1 and 3, those of interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
3 smaller; interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
2 granulategranulate:
pertaining to a coarse, grainy surface texture
near basebase:
point or edge closest to the body; opposite of apex
, interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
4 granulategranulate:
pertaining to a coarse, grainy surface texture

relating to end of the side part/portion
margin armed with alternating spinesspine:
an elongate projection of the exoskeleton that is longer than its basal width
