Hyposoter pechipogator Galsworthy & Shaw sp. nov.

( Figs. 26–28 )

Diagnosis. In the group with black metasoma, pale fore and mid coxae, and more or less orange hind tibiae, this species can be distinguished from all but H. monensis by its rugose area petiolaris. It can be distinguished fairly easily from the latter by the presence of strong punctures on the lower mesopleuron, and the emarginate seventh tergite.

Description. Female. Fore wing length: 5 mm.

Head: face longer than broad, granulate, with rather small punctures spaced more than one diameter apart; clypeus rather broad and only shallowly convex, the punctures a little larger and closer than on face, with apical margin narrowly smooth and outflexed; mandibles yellow, only slightly tapering; frons and vertex sculptured as face, temples abruptly narrowed and almost flat behind eyes; first flagellomere about 5.0x longer than wide, both antennae of unique holotype missing apical flagellomeres.

Mesosoma: mesoscutum granulate and rugose at rear and along lines of notauli, which are not however incised; upper part of mesopleuron, including speculum, very evenly and finely granulate throughout, unpunctured except along leading edge; lower mesopleuron granulate with rather close deep punctures throughout; metapleuron and hind coxa similarly sculptured, but with slightly finer punctures; upper face of propodeum finely granulate, but petiolar area, especially lower part, becoming rugose; area basalis a short triangle; area superomedia lozenge-shaped, its front edges clearly defined and continuing into costulae, the edges behind the costulae only faintly indicated, and the rear boundary formed by the apex of the strong triangular carinae defining the petiolar area.

Wings narrow, 1 cu-a slightly postfurcal, areolet very small and long-stalked, nervellus slightly curved.

Metasoma: petiole of first segment smooth, shiny and unpunctured; postpetiole finely granulate, unpunctured, very rounded and convex, with a marked longitudinal pit at base; other metasomal segments very finely granulate and finely punctured, seventh segment with a V-shaped emargination; ovipositor sheaths slightly shorter than depth of metasoma.

Colour: black; antenna dark brown, tips of scape and pedicel with small yellow spots; fore and mid coxae, trochanters and trochantelli yellow, mid coxa orange at base; hind coxa black; rest of legs uniform orange; second metasomal sternite clear yellow, other sternites dark brown, except for a small amount of yellow on distal margins.

Holotype: ♀, Wyre Forest , Worcs, SO 744761, UK, ex Pechipogo strigilata , em. 1.8.2002, D.Grundy (per M.Bloxham). ( NMS).

Male unknown.

Biology. The unique holotype was reared in the UK from a larva of Pechipogo strigilata (Linnaeus) ( Lepidoptera , Erebidae ) by D. Grundy (per M. Bloxham).

Remarks. The holotype has the metasoma and the right fore wing mounted separately on a card on the same pin. A second female specimen in the NMS collection, Malaise trapped, agrees very well with the description of the holotype in most respects, including the heavy and obvious punctation on the lower mesopleuron, and the longitudinal pit at the base of the postpetiole, but has a longer area superomedia with the apical edges better defined. It may well belong to the same species. Details are: ♀, Abbots Moss, Cheshire, SJ5868, Malaise trap 2, Quercus/Betula/Pinus, 25.viii.–21.ix.86, R.R.Askew NMSZ 1988.002.
