Cryptognatha aethiops Crotch Cryptognatha aethiops Crotch 1874: 206 ; Korchefsky 1931: 219 ; Blackwelder 1945: 449 . Description. Female holotype . Length 3.4 mm , width 3.2 mm . Dorsal surface shiny except head dull, alutaceous. Color black; head with vertex black, apex of black vertex irregular; pronotum with anterolateral angle broadly yellow ( Fig. 113 ); median projection of basal abdominal sternum black, legs and abdomen reddish yellow ( Fig. 114 ). Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than a diameter to twice a diameter, becoming gradually larger toward lateral margin; prosternal punctures small, indistinct, mesosternal punctures large, separated by less than a diameter, metasternal punctures small, separated by two or three times a diameter medially, absent in lateral 1/3; basal abdominal ventrite with coarse punctures separated by about a diameter medially, lateral 1/3 of ventrite lacking punctation, ventrites 2–4 finely punctured, punctures separated by about a diameter, ventrite 5 with dense, fine punctation. Head with frons parallel-sided, medially depressed, 1.5 times as wide as eye, apex weakly arcuate, lateral 1/8 slightly retracted, angle acute; eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side extended from apex of intercoxal process 1/3 distance to apex of prosternum, straight. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 2/3 distance to rear margin of ventrite. Male. Unknown. Variation. Unknown. Type locality. Colombia . Type material. Holotype , UMZC. Geographical distribution. Colombia . Specimens examined. 1, holotype . Remarks. This species is known only from the female holotype , making it difficult to distinguish from other entirely black species except by its Colombian origin. Similar appearing species are known from Brazil . In addition, C. aethiops is at least slightly larger than other entirely black species. The holotype of C. aethiops in the Crotch collection is labeled “Columbia/Hoffm./ aethiops Boh. ”
