Cryptognatha clarki Crotch Cryptognatha clarki Crotch 1874: 207 ; Korschefsky 1931: 219 ; Blackwelder 1945: 449 . Description. Male. Length 2.0 mm, width 1.8 mm . Dorsal surface shiny except head densely alutaceous. Color dark blackish brown; head yellow; pronotum black with lateral 1/8 yellow; elytron with lateral 1/4 black, bordering large, obscurely defined blackish brown central macula ( Fig. 62 ); venter brown except mouthparts, legs yellow; abdomen yellow except apex of median 1/3 of ventrite 1 dark brown. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by a less than a diameter to twice a diameter, becoming gradually larger toward lateral margin; prosternal punctures large, indistinct, separated by about a diameter; mesosternal punctures larger than on prosternum, separated by less than a diameter, contiguous, metasternal punctures large, separated by 2 or 3 times a diameter medially, entirely 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, 2.5 times as wide as eye, clypeal apex arcuate medially, lateral 1/8 slightly retracted, angle acute ( Fig. 63 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side extended from apex of intercoxal process 3/4 distance to apex of prosternum, strongly curved laterally. Epipleuron descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 7/8 distance to rear margin of ventrite. Genitalia with penis guide about as long as paramere, basal 2/3 parallel-sided, apical 1/3 abruptly narrowed to small, rounded apex; paramere slender, apex rounded ( Fig. 64, 65 ); penis long, sinuate in apical 1/3, apex shortly attenuate; penis capsule large, wide, inner arm short, apex medially emarginate, outer arm short, large, apex abruptly curved ( Fig. 66 ). Female. Similar to male except head brown ( Fig. 63 ), weakly depressed medially, pronotum entirely black; spermathecal capsule lost. Variation. Length 2.0 to 2.4mm , width 1.8 to 2.2 mm . Type locality. Rio de Janeiro ( Brazil ). Type material. The BMNH holotype is labeled “Type/clarkii/37580/clarkii/Fry RioJan/TYPE.” Geographical distribution. Brazil . Specimens examined. 7. Brazil . Entre Rios; Rio de Janeiro . ( BMNH ) ( CMNH ). Remarks. The elytral color pattern of this species is obscure and poorly defined. The male genitalia, however, are distinctive enough to confirm identification.
