Cryptognatha della Gonzalez and Hanley

20. Cryptognatha della González and Hanley, new species

Description. Female holotype. Length 2.3 mm, width 2.1 mm. Dorsal surface with head dull, strongly alutaceous, pronotum shiny with trace of microsculpture, elytron lacking microsculpture. Color reddish brown; head, epipleuron yellow; pronotum entirely reddish brown; elytron with large, black, median macula extended from base to apical declivity, laterally 1/2 distance to lateral margin (Fig. 106, 107); venter brown; legs yellow. Head without punctures; pronotal punctures small, separated by less than a diameter to twice a diameter; 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, indistinct, mesosternal punctures large, separated by less than a diameter, nearly contiguous, metasternal punctures large, separated by 2 or 3 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, not medially depressed, three times as wide as eye, apex truncate medially, lateral 1/8 slightly retracted, angle acute (Fig. 108); eye canthus long, about 3/4 times width of eye. Prosternum with lateral carina on each side extended from apex of intercoxal process 1/4 distance to apex of prosternum, straight. Epipleuron moderately 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. 109).

Male. Unknown.

Variation. Length 2.3 to 2.4 mm., a single paratype has the black, median, elytral macula brown, not strongly distinctive from color of remainder of elytra.

Type material. Holotype female: PERU: Madre de Dios Dept., CICRA Field Stn, near intrsctn trails 19, 15, and 27, 56713° S 70.09184° W, 270 m. 14.VI.2011, CS Chaboo, ex. Heliconia, PER-11-CSC-026 (MUSM). Paratypes (2): 1, PERU: Madre de Dios: CICRA Field Stn, garden, 12.56940° S 70.10100° W, 260 m, 2-11-X,2010, MJ Endaraa, malaise trap, PER10-10-MAT-018; 1, PERU: Madre de Dios Dept., CICRA Field Stn, trl 6, research plot, 12.55207° S 70.10962° W, Malaise trap, PER-11-MAT-029 (MUSM).

Other specimens. 2. A specimen (USNM) labeled “ Peru, Satipo, V-VI-1942, Paprzycki” has a similar color pattern to that of C. della except for the following differences: length 3.0 mm., pronotum bright yellow with small black macula at base anterior to scutellar shield, lateral 1/2 of elytron with reddish brown more pronounced than that in C. della (USNM). Another specimen (CPGG) labeled “ Peru, Loreto, Padre Cocha, 150 m., 17-III-2006, Leg. R. Westerduijn. Under Heliconia leaves.”

Remarks. Cryptognatha della is recognized by elytra with a large, black, median macula, a character not shared with any presently known species of the genus. The USNM specimen listed as “other specimen” is tentatively regarded as the same species. It is larger with a yellow pronotum, but identical in most other respects including female spermathecal capsule. Another specimen with much different dorsal coloration is also considered this species because of a similar collection locality and identical female spermatheca. This specimen has a black pronotum with lateral 1/8 yellow, elytron entirely black except narrowly reddish brown along lateral margin.
