It appears about 30 years later after the first three papers were published: Zombori 1971, 1972 and 1973. The specimens are collected in summer, mostly in June and July in the high altitudes of the mountainous regions of Mongolia. The material was collected by Dr Zoltán Kaszab between 1963 and 1968. Dominant species: Priophorus hyalopterus Jakovlev, 1891; Pristiphora fulvipes (Fallen, 1808); P. groenblomi (Lindqvist, 1952); P. memoriakaszabi sp. n.; Pristicampus diasphorae Zinovjev, 1993; Amauronematus subfuscus Schmidt, 1997; Pachynematus infirmus (Förster, 1854); Pachynematus clitellatus (Lepeletier, 1823) and P. xanthocarpus (Hartig, 1840). These species are 51% of the total Nematinae species. Types are deposited in the Hymenoptera collection of the Hungarian Natural History Museum.
