Galsworthy, Anthony, Shaw, Mark R. & Haraldseide, Håkon, 2023, A key to European species of Hyposoter Förster, 1869 (Ichneumonidae: Campopleginae) with descriptions of 18 new species, and notes on all included species, Zootaxa 5290 (1), pp. 1-73 : 39-40

Hyposoter cryptocentrus ( Gravenhorst, 1829)

Campoplex cryptocentrus Gravenhorst, 1829 : holotype ♀, in UWCP, examined by Horstmann.

Horstmann (2000) published details of the holotype, which had apparently been earlier labelled, but not published, by Townes, and which he had examined.

We have not seen this species, which is, so far as we know, known only from the holotype, which comes from northern Italy. Its biology is unknown .

Hyposoter culminator Aubert, 1974

Hyposoter culminator Aubert, 1974 : holotype ♀, in MZLS, examined by Horstmann.

The species is superficially similar to H. carbonarius , but is much smaller (wing length about 5 mm, as opposed to about 8 mm in carbonarius ). The mesopleuron is unusually strongly rugose and the metapleuron reticulate-rugose. Hyposoter carbonarius is strongly punctate on the lower half of the mesopleuron, whereas no punctures are visible in culminator . Hyposoter culminator is also similar to H. nigritus , but easily distinguished on the key characters.

Nothing has hitherto been published on the host(s) of the species. However, six female specimens in NMS from the French Alps were reared, four from “indeterminate geometrids ( Idaea /Xanthorhoe or near)”, one from “geometrid on low plants”, and one from a lepidopteran without details. We have seen specimens from the French and Bavarian Alps and Switzerland: it is presumably a montane species. Three specimens from the third author’s collection were barcoded ( BOLD Sample IDs CollHH3477, 3478, and 3479) .
