Hyposoter ruficrus ( Thomson, 1887)

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

Most red-bodied specimens with dark tegulae and red hind femora will prove to be this species. Some specimens of H. dolosus with dark tegulae are similar, but can be distinguished easily by the key characters, particularly the colour of the second tergite. Other species with red on the abdomen, dark tegulae and red hind femora have only very limited red or brown marks at the sides of some of the metasomal tergites.

The species has been reared in the UK from Pyronia tithonus (Linnaeus) and Maniola jurtina (Linnaeus) ( Nymphalidae , Satyrinae ) ( Shaw et al. 2016). We have seen specimens from the UK and Germany. The lectotype was from Sweden. It has also been reported with uncertain reliability from Norway, Finland, France, Hungary, Latvia, and Romania. We have seen specimens taken from July to September, with an even distribution over the period.
