Polacantha
composita is the only species known from NV though this does not prove this specific identity.

Polacantha
Female Polacantha-- they're distinctive among Asilinae for having a long arista but stubby flagellomere, no anterior dorsocentral bristles, an elongated ovipositor, stubby proboscis, and usually reddish/yellowish legs. In other words, a rather remarkable convergence (externally) to Neomochtherus and its allies (also in Asilinae), but the internal male genitalia are rather different. Nice find!
