diophthalmus Daday, 1889 Chthonius diophthalmus Daday 1889a: 134, pl. IV figs 21, 27. Chthonius (Chthonius) diophthalmus: Mahnert, 1978b: 287. Chthonius (Chthonius) heterodactylus Tömösváry, 1883: Gardini, 2014: 107, figs 20–23 (synonymized). Syntypes. HNHM Pseudoscorp-240: 2 ex. “613/1883 Chthonius diophthalmus Daday, det. Dr. Daday Jenő ”, “Mehádia 1881” [Mehadia, Romania]”, “vidit G. Gardini X.2013 ”, [leg. Ö. Tömösváry]. Current status. Junior subjective synonym of Chthonius heterodactylus Tömösváry, 1883 (Gardini 2014). Remarks. The original description mentions that it was based on specimens identified earlier by Tömösváry as “ Chthonius rayi L. Koch ”. Tömösváry’s label has obviously been removed later in this case also (see Introduction). Mahnert (1980a) mentioned that he studied the “ Typus ” in HNHM. Although not mentioned in the original description, Tömösváry (1883: 195) stated that he had collected the specimen.
