Explanation of Names
Parthenicus wheeleri Henry, 2007
named after Dr. Alfred George Wheeler, Jr., collector of the entire series of this plant bug.
Identification
I am sure that this bug is Parthenicus wheeleri in Orthotylinae. According to Henry
(1), P. wheeleri is distinguished by "the the pale testaceous dorsum (figs. 11, 12), occasionally with a few small red speckles on the head, pronotum, and hemelytra, especially in females, contrasted by the brown first antennal segment, scutellum, and hind femur; the lack of spots at the bases of the tibial spines on the front and middle legs and frequently on the hind legs (or with only very faint reddish spots on some basal spines)," etc. It is distributed in Texas and Oklahoma.
The linked paper shows the key, description, and photos of Parthenicus species, and you may confirm my new suggestion.
