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 ).

Abdomen: Sternites III to VI polished, with rows of setigerous punctures across segments ( Fig. 13D ).

Distribution: United States, Mexico, Cuba, Guatemala, Honduras, Costa Rica, Colombia First record— ( Fig. 11 ).

Remarks: See remarks of C. ciliatus .
