RESULTS AND DISCUSSIONS
Xiphinema pachtaicum (Tulaganov, 1938)
Kirjanova, 1951 (Tables 1-3; Figures 1A, 2,
3,5)
Female. Habitus in the shape of a single spiral
or C when relaxed. Labial region 3-4 μm high,
offset from the rest of the body, expanded,
frontally flattened, laterally rounded. Genital
system with two almost equally developed
branches, uteri short. Rectum 23μm long for
Ostrov population, 17-21 μm for Urlai, 21-
24,5 μm for Bîrlad population.
Male. Body posture as in female, tail end coiled
stronger ventrally. Head region as in female, lip
region 4 μm high. Ventromedian supplements
1+5 (Urlai specimen) and 1+6 Nazarcea
specimen). Spicules slightly curved ventrally.
Tail dorsally convex, with elongated mucro.
