Taxonomic list

• The catalogue number of the type of Belebey vegrandis is given as PIN 104/50 in the primary reference of the present collection. Reisz et al. (2007, Zool. J. Linn. Soc. 151(1)) give the same catalogue number for the type specimen of B. vegrandis. Ivakhnenko (2008), however, gives PIN 164/... as catalogue number for the material of B. vegrandis from the present collection. Additionally, Tverdokhlebova & Ivakhnenko (1984) also give the catalogue numbers of the nyceroleterid material as PIN 164/... Thus, PIN 164/... here is considered the correct catalogue number for the material from near the town of Belebei.
