Autapomorphies of Leentvaaria.

(1) Labial palp is enormously elongate, its 1st and 2nd segments are very long, each more than twice longer than paraglossa; 3rd segment retains normal size (Demoulin 1966a: Fig.8).

Plesiomorphies of Leentvaaria. Each tergalius I–VII has both lamellae simple, terminated by a single process, without other processes or projections (unlike Hermanella/g3, Hylister and Traverella); not oval (unlike Needhamella/g1) [see Leptophlebia/fg1 (10)].
