Sericostoma flavicorne Schneider, 1845 sensu lato

Material examined. 1♂, 3♀♀, KOSOVO, L1 Ujman (42°56'41.514"N, 20°39'39.06"E) ; 1♂, 2♀♀, KOSOVO, L2 Koshtovë (42°52'0.8148"N, 20°48'42.7788"E) ; 3♂♂, 3♀♀, KOSOVO, L4 Revatskë (43°11'30.8472"N, 20°42'39.0204"E) .

Remarks. Sericostoma flavicorne Schneider, 1845 sensu stricto is most likely restricted to Turkey, from where it was described, as proved by recent investigations (e.g., Sipahiler, 2021). Sericostoma schneiderii Kolenati, 1848 was originally described from Croatia. Malicky (2004) synonymized several Sericostoma species under S. flavicorne , including S. schneiderii . Recent detailed investigations have reaffirmed the status of these species and led to the description of several new ones (e.g., Sipahiler, 2021; Olah & VinÇon, 2023). In the Balkans, Sericostoma specimens have been reported as both S. flavicorne and S. schneiderii . However, these reports of S. flavicorne should be understood in a broader sense referring to Malicky (2004), as is the case in this study. It is likely that S. schneiderii is the only species present in the Western Balkans, but this hypothesis requires confirmation through detailed morphological examinations of different populations. In some male specimens collected in the Ibër River, it is obvious that lateral prolongation of segment X have a small projection on the dorsal branch, which is not as big as in S. flavicorne , but still visible. While this is atypical for S. schneiderii , it can also be a variation.
