16. Cryptognatha yolandi Crotch

Cryptognatha yolandi Crotch 1874: 206 ; Korschefsky 1931: 220; Blackwelder 1945: 450.

Description. Male. Length 2.3 mm, width 2.0 mm. Dorsal surface weakly alutaceous with head densely alutaceous, pronotum and elytron with slight trace of microsculpture. Color black; head yellow; pronotum with lateral 1/3 yellow ( Fig. 86 ); venter yellow with prosternum brown in lateral 1/3, mesosternum, metasternum and epipleuron brown; abdomen brownish yellow except median portion of basal abdominal ventrite brown. Head with punctures hidden in microsculpture; pronotal punctures small, separated by a diameter or less; elytral punctures slightly larger than on pronotum, separated by less than a diameter to three times a diameter, becoming gradually larger toward lateral margin; prosternal punctures small, separated by a diameter or less; mesosternal punctures larger than on prosternum, separated by less than a diameter, metasternal punctures larger than on mesosternum, separated by a diameter or less, entirely absent in lateral 1/4; 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 slightly widened toward apex, medially depressed, 1.5 times as wide as eye, clypeal apex arcuate, lateral 1/8 slightly retracted, angle acute ( Fig. 87 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side angled laterally, extended from apex of intercoxal process about 1/3 distance to apex of prosternum. Epipleuron moderately descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 3/4 distance to rear margin of ventrite. Genitalia with phallobase long, penis guide slightly longer than paramere, slender, evenly narrowed from base to abruptly rounded apex; paramere long, slender, apical 1/8 slightly widened, curved to rounded apex ( Fig. 88, 89 ); penis long, slender, apex acute; penis capsule slender, inner arm short, apex rounded, outer arm short, tapered to rounded apex ( Fig. 90 ).

Female. Unknown.

Variation. Unknown.

Type locality. Ega ( Brazil).

Type material. UMCZ (holotype, Gordon 1987).

Geographical distribution. Brazil.

Specimens examined. Holotype.

Remarks. As with most other dorsally black species of this genus, male genitalia must be examined to permit identification. The long, slender penis guide is a character not shared with other known species and is most similar to that of C. pudibunda .

The holotype was not in good condition when dissected and is less so now. Both elytra became detached and are now glued on the point next to rest of the specimen.
