Autapomorphy of Leucrocuta/f1=Afghanurus/g1.

(1) Ventral sclerites of penis distad-laterad of titillators [see Pentamerotarsata (5)], bear one or several pairs of denticles ("discal spines") directed distally-laterally (Kluge 1980: Fig.64,71,83,90,103). Only in a few species these "discal spines" are secondarily lost.

Character of Leucrocuta/f1=Afghanurus/g1 of unclear phylogenetic status.

(2) In male imago 1st segment of fore tarsus is always short, several times shorter than 2nd segment. Non-unique character (see Index of characters [2.2.76]).

Plesiomorphies of Leucrocuta/f1=Afghanurus/g1. Median titillators of penis [see (1)] are well-developed, contiguous medially (unlike Afronurus/g1). Larval pronotum has no posterolateral projections (unlike Ecdyonurus/fg2). Distal dentiseta is simple (unlike Atopopus/fg1).

Size. Fore wing length 510 mm.

Distribution. Holarctic (dominate in Eastern Palaearctic and Nearctic).
