Anilastus thuringiacus Schmiedeknecht, 1909

This species is absent from Horstmann’s key and there is only a short MS note, which has not been completed, suggesting that he failed to find the holotype. It is not mentioned in Oehlke and Townes’ (1969) review of the type material from Schmiedeknecht’s collection in Rudolstadt, and we have not been able to find any published record of its location. The species was described from a single female from Blankenburg in Germany. There is a series in Horstmann’s collection (2♀, 1♁) which had originally been marked with this species name by Horstmann, but with labels subsequently added that correct the determination to Hyposoter dubitatus Holmgren. They are identical to the holotype of H. dubitatus , which we have examined, but there is no evidence as to whether Horstmann intended to synonymize the two names. In the absence of further information on the holotype of thuringiacus , we regard it as a nomen dubium. It is on the British checklist ( Broad, 2016) by virtue of some dubious references in Johnson (1929) and Carr (1924), and we suggest that it should be removed.
