Morphology and Anatomy:

The species name refers to the city of Amol, Iran, which is near the area where the species was dicovered.

Female:

• Vermiform, wide, irregularly ventrally curved after fixation.

• Cuticle thin, finely annulated with five to six lines in the lateral field.

• Lip region low, continuous with the body contour.

• Stylet short, conus as long as the shaft or slightly shorter, small knobs distinct.

• Dorsal gland orifice close to the stylet knobs.

• Corpus muscular, wide, slender, isthmus lacking, pharyngeal glands forming long dorsal overlapping.

• Phyaryngo-intestinal junction anterior to the nerve ring and excretory pore.

• Intestine simple, rectum and anus functional.

• Monodelphic-prodelphic, ovary long, usually reaching nerve ring, reflexed once or twice in some individuals, oocytes in multiple rows close to the germinal zone, reducing to two rows distally,

• Oviduct and spermatheca indistint, crustaformeria formed from multiple cells, joining to the uterus; vagina with sclerotized walls,

• Vulva a transverse slit with protruding lips and the postvulval uterine sac absent.

• Tail conical, short, with wide rounded tip dorsally bent in fresh females in water.

Male:

• Unknown

Feeding:

 Siddiqi (2000) considered nematodes in the family to have “two types of generation, one free-living, fungus- or plant-feeding, another involving a heterosexual female parasitic in the insect haemocoel”. The feeding habit and generation status of A. amolensis is unknown

In molecular analysis, Anguillonema amolensis  formed  a clade with a specimen of Howardula (family Allantonematidae) and with two species of of Parasitylenchus (family Parasitylenchidae). Thus it is probable that the suborder Hexatylina of the order Tylenchida is not monophylatic (Mobasseri et al., 2017).
