Pseudoclastoptera Hamilton gen. nov.

Type-species: Pseudoclastoptera irrubesco sp. nov.

Etymology. pseudo - (adjective), Latin for “false”; Clastoptera (f), genus of Clastopterinae

Diagnosis. Crown short, broadly rounded, three-fifths as long as wide, tylus shorter on midline than crown, its defining sutures ending abruptly just in front of ocelli; antenna with short postpedicel partially withdrawn into tip of pedicel, bearing arista on anterodorsal edge, a central globular basiconic sensillum almost entirely withdrawn into prominently rimmed pit, and behind this a large pit containing several coeloconic sensilla surrounded by prominent marginal spines ( Figs 30–31 C) that obscure the number of sensilla, which apparently number at least 7; rostrum extending beyond mesotrochanters but not beyond hind coxae; head narrower (0.75–0.80×) than pronotum, lateral margins of pronotum scarcely 0.3× as long as interocular distance; rostrum extending beyond mesotrochanters but not reaching hind coxae; pronotum shiny, obscurely punctured; scutellum weakly convex. Tegmina smooth except for small punctures (more prominent than those on thorax), opaque, veins strongly indicated only on claval suture and basal half of large costal plaque ( Fig. 4 B). Hind wing with 4–5 tiny hooks on large, triangular process of costal margin. Fore femur slender, 1.3 × as long as stouter hind femur; hind femur slender, 4 × as long as wide across apex; pectens of hind tibia with 10–13 spines, those of basitarsomere with 8–10 spines, of second tarsomere with 7–9 spines with long setae. Male anal tube with large, oblique basal segment; paraprocts nearly as long as 11th segment including epiproct; pygofer weakly scleritized, ventrolateral process an inturned spine, dorsal process large, triangular, articulated ( Fig. 5 C); subgenital plates fingerlike, weakly articulated ( Fig. 5 B); style as in Pseudomachaerota ; theca heavily sclerotized, stout, in lateral aspect curved apically, truncated ( Fig. 5 C), in posterior aspect narrowed just before enlarged, cordate base, tapered beyond midlength, fringed with serrate flange around gonopore on posterior face ( Fig. 5 D). Ovipositor 2nd valvulae 1.2 mm long, slender, weakly curved and tapered ( Fig. 17Q ).

Included species. Two new species, differing chiefly in colour, and a possible third known only from an unassociated female.
