328 Euura oehlkei (Muche, 1973)

Fig. 107

Pachynematus oehlkei Muche, 1973b: 167–169 . Holotype ♀, not found in ZMHB (GBIF-GISHym2786), but the slide preparation of the lancet was located. Type locality: Kazakhstan, Alma-Ata , Medeo.

Nematus (Pachynematus) tarani Zhelohovcev, 1976a: 62–63 . Holotype ♀ (ZMMU?), not examined. Type locality: Uzbekistan, Fergana District. Synonymized with oehlkei by Muche (1981).

Diagnosis

The species is very similar to E. annulata and E. gehrsi , and synonymy with one of them cannot be excluded. The lancet of E. oehlkei has a concave or straight ventral margin while it tends to be slightly convex in annulata and gehrsi , but the significance of this difference remains unclear. The drawing of the lancet of tarani ( Zhelohovcev 1976a) does fit very well with the lancet of oehlkei . Muche (1973b) and Zhelohovcev (1976a) also described males which are similar to gehrsi in their dark colouration. Muche’s (1973b) drawing of the penis valve does not seem to be entirely accurate, but Zhelohovcev’s (1976a) drawing fits best with gehrsi in overall shape, although the size of the valvispina fits better with annulata .
