Coelioxys (Hemicoelioxys) Pasteels, 1968

= Coelioxys (Hemicoelioxys) Pasteels, 1968 .

Type species: Coelioxys apicata Smith, 1854 .

Diagnosis: Species of the subgenera C. (Liothyrapis) and C. (Torridapis), as well as C. (Allocoelioxys) madagascariensis are the only ones within Coelioxys with bare eyes ( Fig. 4 View Figures 4 and 5 ). The species C. madagascariensis is differentiated from C. (Liothyrapis) spp. by the sharply carinate lateral margins of the axilla ( Fig. 6 View Figures 6 and 7 ). The most easily observed characteristics that separate C. (Liothyrapis) spp. from C. (Torridapis) are [alternative conditions in C. (Torridapis) are given in parentheses]: axilla short, free apical portion not produced beyond posterior margin of mesoscutellum (Figs 7, 8) (long, free apical portion produced beyond posterior margin of mesoscutellum; Fig. 11 View Figures 8–13 ); T 6 in females ending in a long spine-like process, with some long, erect hairs subapically ( Fig. 9 View Figures 8–13 ) ( T 6 ends in a very short, obsolescent spine-like process and lacks long, erect hairs subapically; Fig. 12 View Figures 8–13 ), and S 6 in females broad and constricted medially, bearing a dense fringe marginally ( Fig. 9 View Figures 8–13 ) (S6 very elongate, never constricted medially and lacking a dense fringe on lateral margins; Fig. 12 View Figures 8–13 ).

Comments: This subgenus is mostly Afrotropical, with some species in the Indomalayan region and others in the Palaearctic. Additionally, one species, C. apicata , has been introduced into Puerto Rico ( Genaro & Franz, 2008). There are at least 24 species assigned to C. (Liothyrapis) ( Ascher & Pickering, 2015). The Afrotropical fauna was revised by Pasteels (1968).
