The genus Pseudosinella Schäffer, 1897 (Collembola, Entomobryidae) in Hungary

A checklist with distribution data of the collembolan genus Pseudosinella of Hungary is presented in this paper. In addition to available relevant references, unpublished data from newly collected material is also included. To date, the occurrence of 23 species of this genus has been confirmed in Hungary, for which a dichotomous key is also provided. Since the publication date of the Hungarian Collembola checklist, a total of nine additional Pseudosinella species have been recorded in the country. In this study, P. edax Gisin, 1967, P. noseki Rusek, 1985, and P. thibaudi Stomp, 1977 are cited for the first time. Up to now, three species of Pseudosinella, namely P. argentea Loksa, 1960 nec Folsom, P. csafordensis Winkler & Mateos, 2018, and P. dungeri Winkler & Mateos, 2018, are recognized as endemic to Hungary.
