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 10–14 mm.
Distribution. Holarctic.
