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 (

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.
