authority Thomac C. Barr and I are in the process of describing a new species of the subterranean genus Rhadine
. It is tentatively named "Rhadine nebraskana
" for good reason. We are aware of only four such specimens (just males!) from Nebraska prairies in Hooker Co. and Banner Co. All were taken from pitfalls presumably near mammal burrows, most likely that of pocket gophers. Our paper could include a key to other members of the larvalis
species group sensu Barr (1974).
Some key external traits of this new species are as follows:
1) coloration is uniformly blackish (mature adults of most species are pale); 2) relatively large (apparent body length 11.5 - 13 mm); 3) elytral apices are not acutely prolonged; 4) mentum without
a pair of prominent pubescent foveae (circular pits).
We are requesting additional specimens for loan study and collection records that expand its range. Please reply here or privately by e-mail (see my profile) if you are aware of such specimens in your personal collection or in an institutional collection. We suspect that more "gopher hole pairies" of north-central North America are home to Rhadine nebraskana
and possibly other undescribed species. Thank you.
