Autapomorphies of Parameletus/fg2.

(1) 2nd (penultimate) segment of labial palp with inner-apical projection (Bengtsson 1930: Fig.18). Non-unique apomorphy (see Index of characters [1.1.58]).

(2) On hind wing MP lacks triad, MP2 and iMP being lost; thus only two triads are present RS and MA [see Euplectoptera (1)] (Kluge 2004: Fig.19:C).

Plesiomorphies of Parameletus/fg2. Unlike Siphlonisca: maxilla with developed apical-ventral row of slightly pectinate setae [see Plesiomorphies of Siphlonurus/fg1]; imaginal and subimaginal abdomen has no lateral lobes.

Size. Fore wing length 1014 mm.

Distribution. Holarctic.
