Type species A. hyparrheniae (Corbett, 1966) Brzeski, 1981 syn.
Anguina hyparrheniae Corbett, 1966
Ref: Brzeski, 1981
The main difference between Afrina and
other genera in the subfamily Anguininae, particularly the genus Anguina,
is that the crustaformeria of the female gonad in Afrina consists
of four rows with 14 cells per row while in
Anguina
species there are 6 to 12 rows with 20 to 60 cells per row (Brzeski,
1981). Brzeski indicated that the tail of Afrina is mucronate
in both sexes and certainly there seems to be a fine point or
projection. Also, he considered the the male bursa is lobed;
however, that distinction does not appear in the descripions of several
of the species.
Andrassy (2007) considered the
Afrina to be a junior
synonym of Subanguina, but that
synonymy has not been generally accepted.
