Habitat: Cave. Remarks: Dragan Antić has called our attention to the strange case of “Protoserbosoma tuberculata Makarov,
Mitić & Tomić, 2005” which was recorded from Prekonoška Cave in a faunal list for caves and cavities
in the northwestern part of the Svrljiške Mountains, East Serbia (Nešić et al. 2007). However, a genus and
species of this name has never been described, and both names are obviously nomina nuda. Prekonoška
Cave is the type locality for Perunosoma trojanicum, and the nomen nudum almost certainly refers to
this species.
