Xie and Feng (1996) from soil around roots
of water spinach (
Ipomoea aquatica
) in Chi-
na. The morphological and morphomet-
rics character of the recovered species are
in agreement with those of original descrip-
tion. This population is characterized by
having lateral field with four lines, head con-
tinuous to slightly constricted, 9-11 μm long
stylet, andfiliformtail. It canbedistinguished
from
F. vulgaris
(Brzeski, 1963) Lownsbery
and Lownsbery (1985) by the shape of head
region (rounded, from continuous to slight-
ly constricted, smooth
vs
mostly trapezoid
in outline, sometimes rounded, continu-
ous with 4-5 annuli), the range of T/VA ra-
tio (1-1.1
vs
1.2-1.7) and common of males.
This species was recovered in 6.66% of soil
samples (15 females and 8 males) from the
Figure 2.

Female lateral field at mid-body; C: Vulval region; D: Female
tail; E: Male tail (Scale bars: 10 μm).
