Frons and clypeus flat, coarsely punctuate, without striae. Labrum short and wide, rounded apically, plurisetose. Left mandible appearing bidentate. Antennal club flat and triangular (most likely deformed).—
Pronotal disc coarsely punctuate, broadly rounded basally, anterior angles pointed. Lateral margin finely crenulate. Scutellar shield hidden. Elytra expanded laterally in basal third, surface of elytral disc coarsely punctuate and finely setose, without striae. Epipleura punctate, but not striate. Prosternum short and wide. Prosternal process widely rectangular anteriorly, coarsely punctuated with crenulate margin and lateral fissures for antennal passage. Antennal clubs rest in shallow cavities located in anterior prosternal angles. Prosternal lobe not distinct. Meso- and metaventrite coarsely punctuated. Metaventrite with recurved postcoxal striae.—
Profemur flattened, with a groove for protibial reception. Protibia slightly expanding apically, outer margin rounded in apical half, bearing few short spines; protibial apex with a small tibial spur. Protarsomeres short, terminal as long as 3–4 combined. Middle leg similar to front leg. Metafemur swollen with setae dorsally, metatibia slightly expanded apically, with several small setae along outer margin increasing in size apically and with a tibial spur. Tarsomeres short, terminal tarsomere as long as tarsomeres 3–4 combined; tarsomeres 1–4 bearing single pair of apicoventral spines.—
First abdominal ventrite punctuated with the same coarseness as metaventrite. Other visible abdominal sclerites (incl. pygidium) with finer punctuation. Propygidium short and wide, largely concealed by elytra.

Despite appearing somewhat similar in the sole specimen of this new species, we believe that the odd antennal club shape is a postmortem deformity caused by collapse of a poorly sclerotized structure, as its exact shape varies considerably among available specimens (compare, e.g. Poinar and Brown’s figs 2 vs. 3). Further, although the tribal separation of
