description: 14. Cryptognatha weisei Brèthes
Cryptognatha weisei Brèthes 1925a: 8; Korschefsky 1931: 220; Blackwelder 1945: 450.
Description. Male. Length 1.6 mm, width 1.5 mm. Dorsal surface shiny with distinct pronotal microsculpture, elytron with faint microsculpture. Color black; head yellow; pronotum with lateral 1/8 yellow (Fig. 77); apex of elytron narrowly yellow; venter with prosternum, epipleuron yellowish brown, meso- and metasternum brown, remainder of ventral surface and legs yellow; abdomen brownish yellow. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures smaller than on pronotum, separated by less than a diameter to 3 times a diameter, becoming gradually larger toward lateral margin; prosternal punctures coarse, sparse, mesosternal punctures large, separated by less than a diameter, nearly contiguous, metasternal punctures large, separated by two or three times a diameter medially, fine and sparse in lateral 1/3; basal abdominal ventrite with fine, indistinct punctures, ventrites 2–4 finely punctured, punctures separated by about a diameter, ventrite 5 with dense, fine punctation. Head with frons slightly narrowed between eyes, medially depressed, 1.5 times width of eye, apex faintly curved medially, lateral 1/8 slightly retracted, angle acute (Fig. 78); 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 nearly as long as paramere, oval, anterior 1/3 abruptly narrowed to sharply rounded apex; paramere long, slender, weakly widened in middle, apex rounded (Fig. 79, 80); penis long, slender, apical 1/4 attenuate; penis capsule with inner arm long, slender, apically tapered to abruptly rounded apex, outer arm elongate, wide, apex broadly rounded (Fig. 81).
Female. Unknown.
Variation. Length 1.6 to 2.2 mm. width 1.5 to 2.0 mm.
Type locality. Brazil, Amazonas, lectotype here designated.
Type material. Lectotype here designated. The BMNH lectotype is labeled “Type/Amazons. 75.8/ Cryptognatha Weise Brèthes ”. Brèthes (1925a) stated that he had two type specimens.
Geographical distribution. Brazil.
Specimens examined. 3. Brazil. Amazonas (lectotype), Minas Gerais, Aguas Vermelhas; MG (Minas Gerais), Ingal, Tangue R.L. (BMNH) (CMNH) (CPGG).
Remarks. This mostly black species is similar to C. latoya in external appearance and male genitalia. It differs from that species by a reduced yellow pronotal area, the apex of each elytron narrowly yellow, and the penis guide about as long as the paramere.
