Hyposoter leucomerus ( Thomson, 1887)

Anilasta leucomera Thomson, 1887 : lectotype ♀ in MZLU, designated by Aubert (1966b), examined by Horstmann.

syn: Limneria tricincta Holmgren, 1858 : Horstmann, 1999

Larger than other similar species other than Hyposoter flavicoxa sp. nov. The hind tibia is striking, with the central colour pale straw, contrasting strongly with the dark basal and apical rings. There is normally a clear black transverse line at the extreme apex of the second metasomal tergite.

This species has been reared from Hellinsia tephradactylus ( Lepidoptera , Pterophoridae ) ( Shaw et al. 2016). We have seen specimens from Norway, Germany and the UK. The lectotype is from Sweden. The species has been reported from countries across Europe from Ireland to Turkey, but many of these are older records whose accuracy is doubtful. Very limited phenological data shows specimens taken in May and August.

One specimen from the third author’s collection was barcoded (BOLD Sample ID CollHH1256).
