I follow this example through Koster's key and get to dapifera pretty straightforwardly. The wing pattern details he relies on are minute. The pattern of coloration of the distal antennal segments (used by Hodges in his MONA fascicle) seem to rule out C. minutella which should have "four [apical] segments of the antenna white preceded by three brown segments, [the next four segments alternating white and brown]", etc. Given that minutella is heretofore only be recited from Florida and the very similar dapifera is known to range to Texas (and beyond), I rather suspect this should be placed in the latter species.

I think I probably can't give a good estimate now. But cool, I'll keep an eye out for more, for measurements and collection. Thanks for the (tent.) ID.
