Cryptognatha flaviceps Crotch 1874: 207 ; Korschefsky 1931: 219; Blackwelder 1945: 449.

Description. Male. Length 2.1 mm, width 1.9 mm. Dorsal surface shiny with faint trace of microsculpture on pronotum. Color black; head yellow; pronotum with lateral 1/4 yellow ( Fig. 73 ); venter with prosternum, epipleuron brownish red, legs reddish yellow; abdomen brownish yellow. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures as large as on pronotum, separated by less than a diameter to 3 times a diameter, becoming gradually larger toward lateral margin; prosternal punctures not visible, mesosternal punctures large, separated by less than a diameter, nearly contiguous, metasternal punctures large, separated by two or three times a diameter medially, fine, sparse 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, twice as wide as eye, apex truncate medially, lateral 1/8 slightly retracted, angle acute ( Fig. 74 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side extended from apex of intercoxal process 2/3 distance to apex of prosternum, curved laterally. Epipleuron moderately descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 2/3 distance to rear margin of ventrite. Genitalia short, penis guide 2/3 as long as paramere, oval, anterior 1/3 abruptly narrowed to sharply rounded apex; paramere long, slender, parallel-sided to rounded apex ( Fig. 75, 76 ); penis lost.
