( MZFS ), specimen dissected, mounted on micro-slide. 8 paratypes females: same location, data and collectors as holotype ( MZFS ), specimens dissected, mounted on micro-slide. Etymology. The specific epithet is dedicated to Dr. Rüdiger Wagner for his important contribution to the study of the taxonomy of Psychodidae . Diagnosis. Male. Head with pair of three branched cornicula and a glandular structure at base of it; eyes separated by 1.5 facet diameters; scape with internal protuberance; interocular suture inverted Y shaped reaching the middle of the vertex; hypandrium subtriangular with microtrichia spread along the sclerite; aedeagus symmetrical, bifid, digitiform; two pairs of parameres, external pair fused apically, inverted V-shaped; internal pair knife-like, ending in curved pointed apex. Female. Cornicula absent; scape without internal protuberance; terminalia with hypopygium trapezoidal; hypogynial valve setose with rounded external margin; cerci two times the length of subgenital plate. Description. Male holotype . Head with large cornicula, three terminal branches and one oval gland in the base. Vertex dorsally expanded, 1.5 larger than wide. Eyes separated by 1.5 facet diameters; eye bridge with four facet rows; interocular suture inverted Y-shaped ending at the middle of the vertex ( Figs. 2A, 2B ). Antenna ( Figs. 2A, 2D, 2E ) with scape longer than the pedicel, inflated on the inner side. Flagellum with 14 flagellomeres; first flagellomere fusiform, 1.2 longer than second flagellomere; flagellomeres 2–13 fusiform with short internodes; flagellomere 14 with apiculus; pairs of filiform ascoids observed in flagellomeres 2 – 11 ( Figs. 2A, 2D ). Relative palpomere proportions: 1.0:1.2:1.6:2.1 ( Fig. 2A ). Wing 3.3 times longer than wide; wing membrane brownish, with costal cell darker; Sc not reaching C; sc-r absent; radial fork distal to medial fork; R 4 ending at wing tip; CuA not reaching wing margin ( Fig. 2F ). Male terminalia: hypandrium subtriangular, apical margin rounded with microtrichia spread along the sclerite; length of gonocoxite 0.6 times the length of gonostylus; gonostyli bare except in the base with patch of alveoli; 1/3 basal of gonostyli inflated; aedeagus symmetrical, bifid, digitiform; two pairs of parameres, external pair shorter than the internal, fused apically forming an U-inverted shaped plate; internal parameres, narrow, well sclerotized, curved apically, ending in pointed apex; ejaculatory apodeme dorsoventrally flattened ( Fig. 2G ); epandrium two times wider than long, with two foramina and two apical patches of alveoli; cercus digitiform 2.2 times the length of epandrium; left cercus with 10 tenacula; right cercus with 11 tenacula; hypoproct and epiproct subtriangular with apical micropilosity ( Figs. 2H, 2I ). Female. Morphologically similar to male, except for the following characteristics: cornicula absent; scape with shorter internal protuberance than male ( Fig. 1C ); terminalia with hypogynium trapezoidal; hypogynial valves setose with rounded external margin; cerci two times the length of hypogynium ( Fig. 1J ). Remarks. Males of eleven species of Lepidiella have cornicula and six of them a scape with an internal basal lobe: L. albipeda , L. cervi , L. monteverdica , L. pickeringi , L. robusta and L. wagneri sp. nov.
