Diagnosis: Dorsal surface of the mandibular plates, smooth; Gonocoxites VIII longer than broad; and ovoid seminal receptacle of the spermatheca.
Redescription. Total length: 7.6–9.0 mm.
Head: surface noticeably convex (Fig. 13A, B), shining, with prominent rugae radiating from base of clypeus, minutely punctate, anterior outline rounded; mandibular plates longer than clypeus and nearly or quite contiguous in front of it, apices recurved; eyes projecting beyond sides of head by not more than one-third their width (Fig. 13B); bucculae less than half as high as labial II, latter without semicircular foliaceous lobe; labium apex reaching between meso- and metacoxae (Fig. 13D).
Thorax: Pronotum with lateral submarginal row of 15 to 18 setigerous punctures; transverse impression weak, with medially interrupted, irregular row of coarse, close-set punctures; anterior lobe impunctate except for moderate punctures laterally and in subapical band, median subapical impression broad, very shallow; posterior lobe impunctate or with a few coarse punctures anteriorly (Fig. 13A). Scutellum disc with few to several widely scattered, coarse punctures. Hemelytron shining, uniformly punctate; clavus with one row of punctures; mesocorium with two rows of punctures paralleling claval suture; exocorium sparsely punctate; costa with six to ten setigerous punctures (Fig. 13A, D). Propleuron shining, with few distinct punctures in depression. Mesopleural evaporatorium not interrupted by pseudoperitreme; anterolateral area polished, impunctate, with few oblique rugae. Posterolateral area polished, impunctate (Fig. 13C). Legs densely covered by long setae; metatibia strongly dilated toward apex, greatest diameter there equal to that of protibia (Fig. 13D).
