Hyposoter pseudovalidus Galsworthy & Shaw sp. nov.

( Figs. 33, 34 )

Diagnosis. The dark tegulae and dark hind femora immediately separate this species from other red-bodied Hyposoter , apart from H. validus and a few specimens of H. dolosus . It can readily be separated from both of these by the unusual shape of the first metasomal segment, which lacks any hint of a glymma.

Description. Female: fore wing 6 mm.

Head: face more or less quadrate, rugose without obvious punctures; clypeus convex, narrow, similarly sculptured, extreme apex sharp and smooth; malar space two thirds of basal width of mandibles; frons and vertex sculptured as face; temples granulate, sharply narrowing behind eyes in dorsal view, width about equal to width of eyes; antenna narrow and tapered to apex, 34–37 flagellomeres.

Mesosoma: mesoscutum granulate and matt, with close-set punctures throughout; pronotum similar, with transverse rugae in addition; mesopleuron entirely matt, finely rugose and granulate with punctures almost hidden, speculum with stronger transverse rugae; metapleuron rugosely granulate; scutellum broad, transverse, rugosely granulate; propodeum similarly sculptured, dorsal and petiolar surfaces curving together without an abrupt transition; propodeal carinae strongly reduced, delineating only a narrow trapezoidal area basalis, and the anterior part of broad transverse area superomedia; costulae present only at base, and petiolar area margined only in dorsal third; petiolar area concave.

Wings: 1 cu-a postfurcal; areolet a broadly-based diamond shape, sessile; nervellus not intercepted.

Metasoma: first tergite narrow and parallel-sided at base, broadening smoothly to a well-rounded quadrate postpetiole, the whole matt with fine sculpture: glymma completely absent. Tergite 2 elongate, gradually broadening to apex; tergites 3–5 elongate, parallel-sided; tergites 6–7 entire; ovipositor only slightly protruding from apex of metasoma, sheaths very short.

Colour: black; apices of fore and mid femora, and rest of fore and mid legs orange; hind tibia orange, the apical quarter darkened; apical half of tergite 2 and the whole of tergites 3 and 4 orange. Sternites 1–2 orange.

Holotype: ♀, Ober-Bayern, Mittenwald , Hasel-Lähne , bei ca. 1000m, 20.vi.1924, E. Bauer ; Anilasta cf valida Pfankuch det A. Roman, Anilasta valida Pfankuch ♀ det. H. Habermehl, [a further handwritten label in indecipherable script], Anilasta valida Pfankuch det E. Bauer, [in Horstmann’s hand] cf. validus ( ZSM). Paratype: 1♀, Ober-Bayern, Garmisch, Ettaler Berg, ca. 800m, 15.vi.1952, A. Dietl, Anilasta valida Pfankuch det E. Bauer. ( ZSM).

Remarks. Male and biology unknown. Identified as an undescribed species by Horstmann.
