brown stainer - Dysdercus obliquus

brown stainer - Dysdercus obliquus
Pharr, Hidalgo County, Texas, USA
December 30, 2007
Size: 10-12 mm
Came to light. Looks like the same species as this pair shot in the same county five days earlier.

Of the eight Dysdercus species listed at nearctica.com, it doesn't look like the three already in the guide, and it's not D. concinnus. Could it be a variation of D. bimaculatus? I couldn't find photos of obliquus or obscuratus, but the description of mimus here doesn't match this specimen.

Likely D. obliquus
Dysdercus bimaculatus and D. obliquus are very similar and primarily distinguished by genitalia. Doesburg's 1968 revision of the genus has maps which suggest that bimaculatus would be expected in AZ and far west Texas, while obliquus is the expected species in the Lower Rio Grande Valley of Texas. As well, from internet images, obliquus appears to have less color contrast on the pronotum, scutellum, etc.

D. obliquus needs a BG page.
