Mordellistena - male

Mordellistena - Male
Somerset, Pulaski County, Kentucky, USA
June 30, 2012
Size: 3.5 mm to apex of elytra
Taken at UV light.

Ridge numbers are 3,3,2 (rudiment of 4th on tibiae). Should be one of the species near liturata, maybe discolor or just a dark liturata?

favor liturata
while this one seems to have characteristics attributed to several species, overall I favor liturata.

discolor - pro: dark/black head and prothroax. con: middle band not reaching suture, legs not black, anal style not black

liturata - pro: middle band not reaching suture, legs rufo-testaceous, anal style same color as elytra. con: dark/black head and prothorax (perhaps a female, which in several Mordellidae have darker head and throax, although not mentioned for liturata?)

masoni should also be considered - same as liturata except pubescence on lateral margin MUST be entire (can't tell from your image), and with several small pubescent spots between bands (not seen in your image, and likely would be visible)

in the end, they all could be the same species. but that will likely take some modern DNA study.
