Maybe V. vinotinctalis?
Val, I see these occasionally as well and have been identifying them as O. vinotinctalis. I can find no illustrations of O. texanalis (not illustrated in the volume by Munroe in his original description in 1976). The only thing Munroe mentions is that the distal half of the fringe of vinotinctalis is buff, compared to "contrastingly white" for texanalis. It certainly appears buff in your critter here. Central Texas is inbetween the cited ranges for the two species, with vinotinctalis occuring "along the Gulf Coast to Brownsville, TX" while texanalis was described from specimens in Jeff Davis and Brewster Cos.

Maybe.
I don't remember all the steps that led to texanalis, but I checked both species at the TAMU collection; and I think there was some other source too. I had originally called them vinotinctalis, but then changed my mind. Anyway, the dark contrasting line in the fringe is quite noticeable - it seems to occur on texanalis and not on vinotinctalis. Some images taken with flash have too much reflection to actually see and compare the wing edge, but it is easy to see in natural light. I'll be at the TAMU insect collection open house this weekend and will put this on my list of queries.
