Morphology and Anatomy:
- Undivided laterally elongated front plate of the head with large, roundish
amphid openings;
- Stylet with about equal parts,
- Vulva surrounded by lateral or longitudinal flaps;
- Males often with large
hypoptygmata. In
Atylenchus, Antarctenchus, and Coslenchus poslonicus the
cloacal opening
is provided with large hypoptygmata; in Aglenchus.
In other Coslenchus species, a
cloacal tube is
present.
- Males present in all genera, but most Coslenchus species appear to be
parthenogenetic.
- Bursa well developed in males of Antarctenchus,
Aglenchus, and Coslenchus, very poorly developed in
Atylenchus and Pleurotylenchus.
- Tail long, attenuated, tail tip setose, acute or finely rounded.
- Phasmids ad-vulval or post-vulval in
Aglenchus and Coslenchus, on the tail in Antarctenchus.
