Paraclius aberrans Robinson, 1964

(Figs 6, 16)

Paraclius aberrans Robinson, 1964: 180, fig. 112. 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.
