Morphology and Anatomy:

Cystoid nematodes in which the body wall of the female does not harden into a cyst.

.

Female: No cyst stage.  

Body globose, with projecting neck; terminal cone well developed, but posterior extremity somewhat flattened.  

Cuticle thick, with superficial, irregular, transverse striae and minute pits between striae; D-layer absent; subcrystalline layer present.  

Excretory pore forwardly situated 27 to 56 �m from anterior end.  

Vulva terminal; vulval slit large, not deeply sunken between hypertrophied vulval lips contituting the terminal cone; no fenestrae; no underbridge; no bullae.  

Anus situated at some distance from vulva, on posterior side of the cone. 

Eggs retained in body.  

Males: Body twisted.  

Stylet less than 30 �m long.

Lateral field with four lines. 

Spicules 30 �m long at most, nearly straight, directed obliquely, with distal extremity pointed.  

No cloacal tubus.  

Tail short, rounded. 

Second-stage Juveniles: Stylet long (35 to 40  µm).

Lateral field with four lines.

Esophageal glands filling body cavity.  

Tail conical, of medium length, with hyaline terminal part half of total length.
