REMARKS

Setae are longer (20-30 µm) than originally described (15 µm). Very similar to Cernosvitoviella aggtelekiensis Dózsa-Farkas, 1970, but the latter species is distinguishable by its larger setae (35-42 µm). A similar observation was made on subterranean specimens identified as C. aggtelekiensis in Giani et al. (2011), which have setal lengths intermediate between those of C. parviseta and C. aggtelekiensis as originally described, while other characters (see Schmelz & Collado 2010) fit both species. Cernosvitoviella aggtelekiensis and C. parviseta have never be redescribed, therefore the degree of intraspecific variability of setal lengths is unknown in both species. The two populations may belong to the same species, which could be C. aggtelekiensis, C. parviseta, or an undescribed species. A reinvestigation of the types of C. aggtelekiensis and C. parviseta is urgently needed.
