Recognition

This species differs from all other species of Cryptodacus by having the face and frons, except between the ocelli, entirely yellow, the scutum without a white band along the transverse suture and without a sublateral white stripe or spot at the intra-alar seta, the discal band not extended across any part of crossvein DM-Cu, and the distance between orbital setae/ distance from anterior seta to eye margin less than 1.0. Other useful diagnostic characters include: ocellar seta moderately strong, longer than posterior orbital seta; ventral margin of face slightly concave, facial ratio (medial height/ ventral width of face) 0.80; first flagellomere entirely yellow, tapered and not strongly sagittally flattened apically, in lateral view 3.0 times as long as wide; notopleuron and katepisternum without white marks; entire dorsal margin of anepisternum white; and syntergite 1+2 entirely brown.

Classification and Evolutionary Relationships

Specimen data
BOLIVIA: La Paz: Zongo [Songo], 1m lectotype of obliquus Hendel 1914a and holotype of obliquus Hendel 1914b (MNM).
BOLIVIA: Suapi, 1m (USNM).
PERU: Vilcanota, 1m (MNM).

Biology
The biology of Cryptodacus obliquus is poorly known. It has not been reared and its host plants are unknown.The larvae probably develop in fruit.

Economic Significance
Cryptodacus obliquus is not known to be economically important.

Comments
Hendel described this species twice, but probably intended to recognize only one species. Norrbom (1994) designated the holotype of C. obliquus Hendel 1914b as the lectotype of C. obliquus Hendel 1914a (described from an unstated number of specimens from Bolivia), making these names objective synonyms as well as homonyms.
