Type locality: USA : Plano, Collin County , Texas , USA . Diagnosis (male). Face narrow (as wide as ocellar tubercle at narrowest point) ( Fig. 6B ); antenna yellow, with apical 2/3 of postpedicel brownish ( Figs 6A, B ); postpedicel slightly longer than wide, rounded at apex. Legs: yellow, except lateral surface of coxa II and all tarsi from apex of basitarsus brownish ( Figs 6A, B ). All tarsi unmodified. Wing hyaline, M 1 gradually angled towards R 4+5 . Hypopygium as long as abdomen ( Fig. 6A ); cercus brownish, branched, dorsal branch short, about 1/4 of length of ventral branch, ventral branch fusiform. Examined type material. HOLOTYPE ♁ (based on photographs) ( Fig. 6 ) labelled as: “ Plano , Texas [ca 33°02′27.4″N 96°44′33.5″W ] | Sep, at night | E.S. Tucker ”; “Taken at | trap light” ; Holotype ♁ | Paraclius | aberrans | H. Robinson ” [handwritten, green label] ( NMNH ) . Remarks. Robinson (1975) noted the similarity between Paraclius aberrans and P. latipes , and both seem to be closely related by sharing the robust and elongate hypopygium, as long as abdomen, and the fusiform ventral branch of the cercus ( Robinson 1964 , fig. 112). Paraclius aberrans can be distinguished from P . latipes by the face being as wide as ocellar tubercle at middle ( Fig. 6B ) (face narrower than ocellar tubercle in P . latipes ( Figs 7B , 8C )) and the cylindrical tarsus I (tarsus I dorsoventrally flattened in P . latipes ( Fig. 8E–G )). Robinson (1964) indicated that species without the conspicuous anterior bend in wing vein M 1 had been described as Hercostomus . Nevertheless, he correctly placed this species in Paraclius by the presence of only five strong dorsocentral setae, two ventral setae on tibia II, and anteroventral preapical seta on femur III, a set of characters found in other species of Paraclius . The holotype of this species was collected at a light trap, an unusual method for Paraclius species. Distribution. USA ( Texas ), Mexico ( San Luis Potosí ) ( Fig. 16 ).
