Classification:

      Tylenchida
       Tylenchina
        Tylenchoidea
        Anguinidae
          Subanguina radicicola (Greeff) Paramonov 1967
  
  Synonyms:
      Heteroanguina (Chizhov, 1980)
      Afrina (Brzeski, 1981)
      Mesoanguina (Chizhov & Subbotin, 1985)
 
Originally assigned to the genus Ditylenchus as D. radicicolus.  Paramonov (1967) erected the genus Subanguina in recognition that the nematode has features intermediate between Anguina and Ditylenchus.  There are around 25 recognized species (Mai and Mullin, 1996).

Morphology and Anatomy:

.

 Median bulb with valves.

Isthmus may be separated from glandular bulb by a constriction.

Esophageal glands may or may not overlap the beginning of the intestine.  

Females:  Mature females swollen or not swollen.

Oocytes of Subanguina are in two rows, not as multiple rows arranged around a rachis as in Anguina; columned uterus with four long rows of cells (about eight/twelve cells per row).  

 
Males: Testis usually without flexures.

Bursa medium sized to long, but not reaching tail end.
