Genus Rajkaella Dragastan & Bucur, 1988

Rajkaella iailensis ( Maslov, 1965) Dragastan & Bucur, 1988

Fig. 5 a-o

This is one of the species first described from Crimea ( Maslov, 1965), as Kopetdagaria iailensis . Afterwards, Conrad & Peybernès (1976) assigned this species to Griphoporella and Conrad & Radoičić (1979) to Pseudoclypeina . Granier (1988, 1990) considered the species invalid. Dragastan & Bucur (1988) designated a lectotype of the species K. iailensis and transferred it to the new genus Rajkaella , an assignment accepted by Granier & Deloffre (1993).

Most of the Crimean specimens were identified in the Belogorsk area. Some others, assigned with some uncertainty to R. iailensis , were collected from the Ay-Petri and Yalta area ( Fig. 6 b-e).
