          Anguina danthoniae (Maggenti, Hart & Paxman, 1973) Brzeski, 1981

    Synonyms:

Described as Cynipanguina danthoniae by Maggenti, Hart and Paxman (1973 and synonymized with Anguina by Brzeski, 1981. Siddiqi (1986) considered Cunipanguina 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, 1981.

Morphology and Anatomy:

      Median bulb with valve;  isthmus separated from the glandular bulb by a constriction;  intestine overlapping the end of the glandular bulb that
      forms a stem-like extension. 

    Oocytes in columns surrounding a central rachis;  columned uterus with four long rows of cells (about 14 cells per row).  Post-uterine sac present.

    Mature females swollen.  

    Testis without flexures, caudal alae
leptoderan, gubernaculum present

Distribution:

Spherical leaf galls  induced by Anguina-like nematodes on California oatgrass, Danthonia californica, were first reported by Weiss (1945) in California and Texas. Twenty years later Jensen et al. (1964) reported similar galls on D. californica from pasturelands near the Oregon coast. Similar material was collected by Maggenti et al. (1973) from the central California coast.

Feeding:

Above-ground parasites of higher plants. The adults are the cryptobiotic stage instead of one of the juvenile stages as in other anguinids.
