description: Hyposoter ruficoxator Galsworthy & Shaw sp. nov.
(Figs. 37, 38)
Diagnosis. One of only two species with an all black metasoma and red hind coxa. It is easily distinguished from the other, Hyposoter coxator, by the colour of the hind tibia, as in the key.
Description. Female: fore wing 4 mm.
Head: face longer than broad, distinctly narrowed ventrally, with close-set punctures distinctly visible on a granulate surface; clypeus fairly narrow, convex, evenly rounded, sculptured as face; malar space about half basal width of mandibles, latter strongly narrowed towards apex, with a wide ventral flange to about two thirds; frons granulate with close-set punctures, the latter disappearing on vertex, except between the two hind ocelli; temples sharply narrowed behind eyes, very short in dorsal view, granulate with small punctures; hypostomal carina disappearing well before meeting oral carina; antenna slender, gently tapering, with 39 flagellomeres in the unique female.
Mesosoma: mesoscutum and scutellum very finely granulate throughout, the lines of the notauli marked by a slight rugosity; pronotum similarly sculptured, without epomia, but with some transverse rugae in lower part; mesopleuron granulate throughout, including speculum, with small rugae in prefoveal depression, and with scattered punctures in ventral part only; metapleuron granulate with punctures; pronotum finely granulate, slightly rougher in petiolar area; carinae very reduced, with only a short basal carina, not reaching the base of the propodeum, the proximal two sides of the area superomedia, and the costulae visible; petiolar area without carinae.
Wings narrow, 1 cu-a interstitial; areolet small, rhomboid, short-stalked.
Metasoma: first tergite with upper side very finely granulate, petiole narrow and parallel-sided until close to apex, postpetiole longer than broad; second and third tergites elongate, dull with very fine sculpture and minute punctures; fourth to seventh tergites progressively more shiny, with more visible, but still very small, punctures; sixth and seventh tergites entire; ovipositor short, projecting very slightly beyond tip of metasoma.
Colour: black; mandibles except for teeth, underside of scape, tegulae, fore and mid coxae and trochanters yellow; apex of clypeus, rest of fore and mid legs, hind coxa, trochanters and femur, and sternites one and two orange; hind femur dull whitish, with very slight subapical dark mark, and apical eighth darkened; hind tarsi dull whitish with extreme apices darkened; tergites two and three with faint reddish wash laterally.
Male: very similar to female, but with more extensive carination on the propodeum, including faint borders to the petiolar area; 38 flagellomeres; colour identical, except orange on clypeus more extensive, and red wash at sides of tergites two and three lacking.
Holotype: ♀, Mergentheim [Germany], 30.vi.1956, red label ‘1070’, label in Horstmann’s hand ‘cf. coxator Hinz’ (ZSM). Paratypes: 2♁, details as holotype. (ZSM).
Remarks. Biology unknown. Identified by Horstmann as a new species.
