Abstract: The only preserved (damaged, sex unknown) type specimen of Periscelis
(Periscelis) winnertzii Egger, 1862 has been revised and designated as a
lectotype. Its revision revealed that P. winnertzii has recently been
misinterpreted and is in fact identical with P. (P.) fugax Roháček &
Andrade, 2017, syn. nov. Therefore, true P. winnertzii is re-diagnosed, with all
its synonomies listed. Periscelis winnertzii auctt. (not Egger, 1862) is
described as a new species, P. laszloi sp. nov., based on a series of specimens
from Hungary (holotype), Portugal, Switzerland and Slovakia. An intersex
specimen of P. laszloi sp. nov., female puparium and cephalopharyngeal skeleton
of 3rd instar larva (ex puparium) of P. winnertzii (all from Hungary) are
described and illustrated. Both species are also characterized by means of the
barcoding region of COI, illustrated in detail (including structures of male and
female terminalia) and their biology and distribution reviewed with new
original data.
