Anguina (Maggenti, Hart & Paxman, 1973) Brzeski, 1981
Genus established as Cynipanguina in the
descriptioon of Cynipanguina
danthoniae by Maggenti, Hart and Paxman (1973) and synonymized with
Anguina by Brzeski, 1981. Siddiqi (1986) considered
Cynipanguina indistinguishable from Subanguina
and synonymized it with that genus although the finger-like extension of the
esophageal glandular region appears to be a distinctive feature. Fortuner
and Maggenti (1987) re-established Cynipanguina but Andrassy (2007)
lists it as a synonym of Subanguina.
However, Cid del; Prado Vera et al (2018)
accept the transfer of Cynipnguina to Anguina by Brzeski,
Body stout, coiled in female, a = 12.1-16.2; body
crescentic in male, a = 16.2-21.4.
Stoma armed with slender stylet.
Metacorpus ovate with small but distinct valve.
Isthmus separated from the glandular bulb by a constriction; intestine overlapping the end of the glandular bulb that
forms a stem- like extension.
Lateral field contains longitudinal, transverse
and oblique striae.
Oocytes arranged around a rachis, post-uterine sac
Oocytes in one/two rows; columned uterus with four long rows of cells (about 14 cells per row).
