Notes. Deltomerus sterbai is a local endemic species confined only to the Pelister Mt. The data for its presence in Bulgaria (Guéorguiev & Guéorguiev 1995: 118; Guéorguiev et al. 1997: 15; Zamotailov 2003: 283) refer to Patrobus atrorufus (Guéorguiev & Muilwijk 2001) .

It seems that some specimens of this species have incorrectly been designated as syntypes or paratypes in DEI, HNHM, and MNHUB. But, they do not come from the type series since D. sterbai was described after two males only. Recently, Viñolas & Masó (2014: 50) indicated that the holotype is kept in DEI, and the paratype is preserved in the Natural History Museum of Barcelona. However, one of us (BG) has visited DEI and found eight specimens of D. sterbai there, three of them designated as syntypes (see also Döbler, 1975: 142). Therefore, the exact place of preservation of the type material of D. sterbai remains an open question.
