An updated checklist for the pseudoscorpion fauna of Hungary (Arachnida: Pseudoscorpiones) Author Novák, János text Zootaxa 2024 2024-04-04 5433 1 51 95 http://dx.doi.org/10.11646/zootaxa.5433.1.2 journal article 10.11646/zootaxa.5433.1.2 1175-5326 10953697 12A37ADF-99A9-4A4D-A8CC-E2C98B8B6D31 Chthonius ischnocheles ( Hermann, 1804 ) Chelifer ischnocheles Hermann, 1804: 118–119 . Chthonius rayi : Tömösváry 1882a: 240–241 . Chthonius ischnocheles : Szalay 1968: 34–35 ; Farkas et al 2009: 69 ; Červená et al . 2020a: 221 ; Gardini 2021 ; WPC 2023. Chthonius ( Chthonius ) ischnocheles : Harvey 1991: 149–151 ; Harvey 2013 . Not Chthonius ischnocheles (Hermann) : Kárpáthegyi 2007: 82 (misidentification; see Chthonius cf. alpicola ). Occurrence: Andorra , Austria , Belgium , Bulgaria , Croatia , Czechia , Denmark , France , Germany , Greece , Hungary , Ireland , Italy , Luxembourg , Malta , Netherlands , Norway , Poland , Portugal , Romania , Serbia , Slovakia , Spain , St. Helena , Sweden , Switzerland , Turkey , United Kingdom , USA (WPC 2023). Reported localities in Hungary : Gyűrűfű ( Farkas et al . 2009 ). New data: nil. Habitat preference: Beier (1963a) reported this species from humid habitats, like in leaf litter or under stones. Legg & Jones (1988) reported its occurrence from beneath stones, bricks and other debris, from woodland soil and litter, and occasionally from birds or other animal nests. In Hungary , it has been reported from oak forest ( Kárpáthegyi 2007 ). Remarks: Chthonius ischnocheles was recently redescribed by Gardini (2021) . Tömösváry (1882a) recorded C . rayi L. Koch 1873 from Mehádia and although this taxon was later synonymized with C . ischnocheles by Chamberlin (1929) , the locality is now located within Romania . There have been two recent records of C . ischnocheles from Hungary : one specimen from Bőszénfa ( Kárpáthegyi 2007 ) and one from Gyűrűfű ( Farkas et al . 2009 ). I have identified the specimen from Bőszénfa as C . aff. alpicola (see above). The other one from Gyűrűfű was also identified by Kárpáthegyi, but it could not be found in his collection, therefore I assume that it have been lost. Altogether, I consider the presence of C . ischnocheles in Hungary doubtful.
