Description. Male holotype. Length 2.6 mm, width 1.5 mm. Dorsal surface slightly dull, with distinct microsculpture. Color dark brown; head yellow; pronotum with narrow anterior border, lateral 1/4 yellow (Fig. 82); venter entirely yellow. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures slightly larger than on pronotum, separated by a diameter or less, becoming gradually larger toward lateral margin; prosternal punctures large, indistinct, mesosternal punctures large, separated by less than a diameter, nearly contiguous, metasternal punctures large, 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, three times as wide as eye, apex truncate medially, lateral 1/8 slightly retracted, angle acute (Fig. 83); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side extended from apex of intercoxal process 1/2 distance to apex of prosternum, curved laterally. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 3/4 distance to rear margin of ventrite. Genitalia elongate, penis guide about as long as paramere, oval, sides parallel in basal 3/4, curved to rounded apex in anterior 1/4; paramere long, slender, narrow in basal 1/3, widened to rounded apex in apical 2/3 (Fig. 84, 85); penis lost.

Female. Similar to male except head brown, pronotum brown with anterior 1/4 yellowish brown; genitalia lost.

Variation. Length 2.6 to 2.7 mm, meso- and metasternum vary from yellow to dark brown.

Type material. Holotype male; Bahia Brazil. (USNM) . Paratypes, 2, same data as holotype except 1 paratype with additional label “ Cryptognatha pudibunda Muls. ” Ch’28. (USNM ).

Remarks. Cryptognatha shelia differs from similar black or dark brown species by a slightly larger size, the male pronotum with a yellow anterior border, and distinctive male genitalia.
