Chthonius hungaricus: Novák & Dányi 2018: 308; Červená et al. 2020a: 221, 225; WPC 2023.
Chthonius pygmaeus: Kárpáthegyi 2007: 82–83 (misidentification).
Occurrence: Hungary, Romania, Slovakia (Gardini 2014).
Known localities in Hungary: Újszentmargita (Mahnert 1980, 1983).

New data: Bükki Őserdő: 10.1975, leg. RS (HNHM Pseud-1302: 1♀); Cserépfalu: 1983, leg. OM (HNHM Pseud-1184: 1 adult); Kerecsend: Fácános-berek, loess oak forest, 14.05.2010, leg. AG, ZG, TN, OM (HNHM Pseud-1694: 1♂).
Habitat preference: Christophoryová et al. (2011c) reported Chthonius hungaricus from the leaf litter of deciduous forests, and from fallen wood in oak forest. From Hungary it was reported from the leaf litter of oak and beech forests and from decaying wood (Novák 2012, 2016), from beech-hornbeam and alder forests (Novák 2018). During the present study it was found in loess oak forest.
Remarks: Chthonius hungaricus was described by Mahnert (1980) from the Hortobágy National Park of the Great Hungarian Plain, and later reported from neighbouring Slovakia (Christophoryová et al. 2011c). During the study of abundant Chthonius material from Transylvania, Romania, Gardini (2014) attributed to C. hungaricus a large number of specimens which had been previously reported as C. diophthalmus Daday, 1889 (Beier 1939a). In Hungary this species also has been reported from the Bükk Mts (Novák 2012), the Buda Mts (Novák 2016), and the Zemplén Mts (Novák 2018).
Chthonius pusillus Beier, 1947
Chthonius (Chthonius) pusillus Beier, 1947: 298–300; Novák 2018: 104.
Chthonius pusillus: Červená et al. 2020a: 221, 225, 226; WPC 2023.
