Abstract

The article provides morphological and molecular description of rare species Malenchus pressulus (Kazachenko, 1975) Andrássy, 1980 which was found for the first time in Poland. Morphology of specimens belonging to Polish population correspond well with previous descriptions of M. pressulus. Howewer, small differences were observed — number of lines on lateral field or number of head annuli between various populations. This article also provides comparison of head morphology of two very similar and difficult to distinguish species: M. pressulus and Malenchus neosulcus Geraert et Raski, 1986. Additionally, for the first time descriptions of partial sequences of 18S rDNA and 28S rDNA for M. pressulus are given.
