10. Cryptognatha karla González and Hanley, new species

Description. Male holotype. Length 1.9 mm, width 1.8 mm. Dorsal surface shiny, pronotum with faint trace of microsculpture. Color yellow; head slightly darkened yellow; pronotum yellow; elytron with large dark brown macula extended from just anterior to humeral callus posteriorly to midpoint of elytron, macula narrow at base, widened to irregularly truncate apex (Fig. 55); venter with metasternum dark brown; basal abdominal ventrite brownish yellow medially. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by a diameter or less, 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 two or three 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, three times as wide as eye, apex truncate medially, lateral 1/8 slightly retracted, angle acute (Fig. 56); 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 moderately descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 3/4 distance to rear margin of ventrite. Genitalia short, penis guide about 3/4 as long as paramere, oval, with apical 1/8 narrowed to abruptly rounded apex; paramere long, slender, apex rounded (Fig. 58, 59); penis long, robust, apex shortly attenuate; penis capsule with inner arm long, tapered to abrupt apex, outer arm elongate, large (Fig. 60).

Female. Similar to male except head weakly depressed; genitalia with spermathecal capsule short, wide, tapered from wide ramus to abruptly rounded apex, portion of heavily sclerotized sperm duct present at base of ramus (Fig. 61).

Variation. Length 1.9 to 3.1 mm, width to 1.7 to 1.8 mm. Pale areas on elytron may be slightly larger or smaller than described above.

Type material. Holotype male: PARAGUAY, Caaguazú, Repatriación. 22-I-2001 (INBP) . Paratypes: 10, Chapada, Brazil, Acc.No. 2966, Aug., Nov., Sept. (CMNH).

Remarks. Typical specimens of Cryptognatha karla are recognized by the dark humeral macula and dark brown metasternum, those specimens lacking a dark macula on elytron are difficult to recognize but they also have a darkened metasternum, which is distinct on an otherwise yellow venter.
