Turbiditylenchus Huston, Khudhir & Hodda, 2024

Type species of the genus: Turbiditylenchus corticeus Huston, Khudhir & Hodda, 2024

Synonyms:

Molecular and morphological analysis, and feeding habits, indicated that the tylenchid nematode extracted from the outer bark of Eucalyptus macrorhyncha differed from all currently described members of Anguinidae sufficiently to warrant erection of a new genus.

Body length 738-1002 um in length, slender, ventrally arcuate.
Lip region continuous, low, cephalic framework weakly developed.
Lateral field with six incisures.
Pharynx with median bulb muscular with strongly refractive valve; isthmus narrow; basal pharyngeal bulb pyriform, slightly overlapping intestine; excretory pore anterior to basal bulb.

Female:

Vulva a transverse slit. Vagina at right angles to body axis or slighly directed forward..
Monodelphic-prodelphic, ovary straight without flexures, posterior with oocytes in a single row.
Spermatheca elongate, 1.6-4.1 times length of ovary, sperm spheroid.
Crustaformeria a quadricolumella of four rows of four cells each.
Post-vulval uterine sac 1.9-4.4 times vbd
Tail conical, terminus pointed
