Pseudotelphusa aenigma (Sattler, 1983) Species

Last modified: Jan. 9, 2023, 2:06 p.m.

For the first time recorded from Belgium at Maasmechelen (LI) in 2019, confirmed by examination of its genitalia. This species can easily be confused with its congeners Pseudotelphusa paripunctella and Teleiodes wagae and the genitalia should be studied. The species is mainly known from the southern parts of Central Europe, though not from most of the Mediterranean countries.
