Description. Female holotype. Length 2.6 mm, width 2.4 mm. Dorsal surface shiny except head less shiny, weakly alutaceous. Color yellow; head, epipleuron yellow; pronotum with seven dark maculae, a single pale brown macula on basal border at lateral 1/8, five dark brown, median maculae arranged in arc on median 1/2 of pronotum; elytron with four dark maculae, a single pale brown macula on sutural border in apical 1/2 narrowly extended along suture to apex, one large, dark brown macula medially in basal 1/2 of elytron, two pale brown maculae medially on apical declivity (Fig. 110); pro- and mesosternum brownish yellow; metasternum dark brown; legs pale brownish yellow; abdomen yellow. 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 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, 1.5 times as wide as eye, apex truncate medially, lateral 1/8 slightly retracted, angle acute (Fig. 111); 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. Genitalia with spermathecal capsule short, gradually widened from base of ramus to abruptly rounded apex of cornu (Fig. 112).

Male. Unknown.

Type material. Holotype female; Bolivia, Upper Mamore R., Sept. 1909, Carn. Mus. Acc. 4043. (CMNH).

Remarks. This species has one of the most striking dorsal color patterns of any species of Cryptognatha, and is somewhat similar to C. gemellata but with a much different arrangement of dorsal maculae.
