Hyposoter pseudodidymator Galsworthy & Shaw sp. nov.

( Figs. 31, 32 )

Diagnosis. Readily separated from otherwise similar species such as Hyposoter didymator and H. barrettii by the reduced contrast in the colour of the hind tibia, which is pale orange rather than white, and with the darkened subproximal and distal bands shading into it rather than strongly contrasting. The yellow fleck at the base of the hind tibia is strongly marked.

Description. Female: fore wing: 4.5 mm.

Head: face about as broad as long, considerably narrowed ventrally; punctation invisible against a strongly granular background; clypeus narrow and very convex; mandibles broad at base, strongly narrowed to apex, with broad ventral flange to two thirds; malar space about equal to basal width of mandibles; frons strongly granular with slight transverse rugosity, vertex and temples finely granulate, the latter strongly narrowed behind eyes and descending abruptly behind ocelli; antenna with 29 flagellomeres, parallel-sided until final 12 flagellomeres gently narrowing, first flagellomere 3.5x longer than wide.

Mesosoma: mesoscutum strongly and closely punctured on a granulate background; mesopleuron anteriorly and ventrally, and metapleuron similar; speculum shining and smooth; depression in front of fovea with strong transverse striation; mesopleural suture with short but strong carinae; propodeum with lateral fields coarsely granulate, area superomedia and area petiolaris strongly rugose; area basalis V-shaped; area superomedia 5-sided, longer than broad, not closed posteriorly; submedian longitudinal carinae and costulae very strong.

Metasoma: petiole of 1st segment rather square in cross-section, broadening gradually to a rather slim, convex postpetiole; glymma small and shallow, about in middle of segment; 2nd segment elongate, 1.5x as long as wide; thyridia large, tear-drop shaped, situated close to base; segments 2 onwards with faint transverse microsculpture and numerous very fine punctures; 6th tergite unmodified, 7th slightly emarginate. Ovipositor about equal to apical depth of metasoma, only very slightly curved upwards and with a strong subapical notch.

Colour: black; mandibles yellow with edges of teeth brown; tegulae and front and middle trochanters and trochantelli yellow; all coxae black; all femora orange; front and middle tibiae orange ventrally, white dorsally; hind tibiae with strong yellowish ring at base, medially orange-brown with darker brown subbasal and apical rings; all tarsi orange brown with small white flecks at base; metasoma with tergite 1 black, tergite 2 black with apical third orange, tergite 3 orange with a triangular black mark at base, tergites 4–5 orange, tergites 6–7 dark brown.

Male unknown.

Holotype: ♀, Spain, Alicante , Moraira, 90m., 14–20.x.1989, garrigue, rec. R. Wahis, Malaise trap; Hyposoter sp. 2 ; cf didymator [latter two labels in Horstmann’s writing]. ( ZSM).

Remarks. Identified by Horstmann as an undescribed species.
