Belonolaimus.
Females. Female annulation 2.2 microns wide anteriorly, 1.5
microns wide in caudal region. Lip region set off from body by a deep constriction,
with 7 to 9 annules and a terminal cap. Stylet with rounded basal knobs
1.4 microns by 4.2 microns. Dorsal gland outlet approximately 2-2.8 microns
from base of stylet. Median esophageal bulb elongate, 17 microns by 21
microns. Hemizonid two or more annules long, anterior to excretory pore.
Excretory pore conspicuous, located 195 microns (170-206 microns) from
anterior end. Ovaries didelphic, outstretched, anterior ovary 22%, posterior
ovary 22% of total body length; with spermathecae containing spermatoza.
Vagina without sclerotized pair of opposing pieces; vulva with protruding
lips. Tail hemispherical; tail length 4.1 (3.4-4.7) times anal body width.
Phasmid 78 microns (62-99 microns) from tip of tail. Lateral alae in the
adults appears as one line extending from the lip region to the terminus
of tail.

in shape, and bearing 7 to 9 annules and a terminal cap. Stylet 87 microns
(84-95 microns) long with weak rounded basal knobs; median esophageal bulb
elongate, 15 microns by 18 microns. Hemizonid about two annules long, anterior
to inconspicuous excretory pore. Testis outstretched. Spicules arcuate,
39 microns (36-41 microns) long measured laterally on chord of arc. Gubernaculum
16 microns (14-17 microns) long with anterior flexure 4.2 - 5.6 microns
