General color pale brown. Head and pronotum without distinctive pigment pattern. Palpi and basal antennal segment pale. Femora with mesal and apical dark bands; tibiae with dark proximal marking. Forewings bearing scattered irregularly shaped pale areas against a slightly darker background. Male. Forewing length 6.5 mm. Posterior margin of tergum 9 with a row of 5-8 long setae ( Fig. 13 ); tergum 10 with a patch of sensilla basiconica on either side of epiproct tip, and a pair of prominent clusters of triangular spines set on sclerite adjacent to epiproct near apical third. Epiproct somewhat triangular in dorsal aspect, with a pair of thin, spine covered processes projecting at apex ( Fig. 13 ). Paraproct outer lobe with a slender and strongly curved outer spine ( Figs. 13-15 ). Cerci globular. Vesicle about twice as long as wide ( Fig. 15 ). Female. Forewing length 8.5 mm. Sternum 7 broadly rounded and overlapping basal half of sternum 8 ( Fig. 16 ). Larva. Unknown. Etymology. The species name refers to the prominently curved, somewhat raptorial-like outer paraproct lobe. Diagnosis. As indicated above under N. clavaloba , this species shares the enlarged, spine-like structure on the paraprocts. These paraproct lobes are acute and slender in lateral aspect for N. raptoraloba and N. tenuiloba (described below) but club shaped in N. clavaloba . Nemoura raptoraloba has a cluster of spines on tergum 10 adjacent to the epiproct which are absent in N. tenuiloba and the epiproct is more quadrangular in outline for the latter species.
