GRACILIPSODES AOUPINIENSIS SP. NOV. (FIGS 2, 13)
Diagnosis: This species is distinguished from G. lanceolatus sp. nov., G. grandis sp. nov.; G. psocopterus , and G. similis by the tibial spur formula of 2, 2, 2, and by the presence of a pair of pre-apical lateral processes of tergum X originating at the apical half of the segment. It is separated from G. aureus sp. nov. and G. robustus sp. nov. by having more hind tibial spines, in the genitalia, by the longer lateral processes of tergum X, and in the forewing, by the longer crossvein m–cu being sharply angled to M. It is separated from G. aurorus sp. nov. by lighter body colour, the slit tergum X apex, and the higher number of hind tibial and mesal spines on the apical part of the inferior appendage. It is distinguishable from G. koghiensis sp. nov. by the shorter superior appendages and shallower apical slit of tergum X.
Description, male: Body and wings brown (in alcohol). Tibial spur formula: 2, 2, 2. Hind tibiae each with 26 small black spines (N = 1). Forewing (Fig. 2A): length 7.9 mm (N = 1), apically rounded; forks 1 and 5 present; crossvein m–cu about as long as crossvein
