The new species runs in the most recent key to the Palaearctic Ceratophysella species ( Thibaud et al., 2004) to couplet 11 which needs to be modified as follows:

11 Sensillum p 5 on abd. I small, spine-like; micro- and macrosetae clearly differentiated................................................ 11*

– Sensillum p 5 on abd. I long, hair like; micro- and macrosetae weakly.. differentiated........................... microchaeta ( Babenko, 1994)

11* Maxillary head of the armata type without prolonged lobe on lamella 5........................................ brevisensillata Yosii, 1961

– Maxillary head with prolonged denticulate lobe on lamella 5 (Figs 16-17)................................................... lobata sp. n.
