Remarks: Four varieties (subspecies) of
Nais paraguayensis
were described:
aequalis
Stephenson (1920)
,
barkudensis
Stephenson (1921)
,
ghanensis
Hrabe (1966)
and
Dero (Aulophorus) paraguayensis aequatorialis
Cernosvitov (1938b)
. The impropriety to put
paraguayensis
under
Dero
was demonstrated by
Sperber (1948)
. The taxonomical value of
aequalis, barkudensis
and
aequatorialis
is seem sometimes at subspecific level (
Stephenson, 1923
;
Marcus, 1943
;
Grimm, 1974
), sometimes as single synonyms of
paraguayensis
(
Sperber, 1948
;
Brinkhurst, 1971b
;
Harman
et al.
1988
). We consider
aequalis
,
barkudensis
and
aequatorialis
as independent species due to differences in the origin of the dorsal setae, shape of the needles and of the anterior ventral setae and because the circumtropical distribution of the typic form of
paraguayensis
makes difficult the subspecific isolation. According to
Hrabe (1966)
the distinction between
Allonais paraguayensis ghanensis
Hrabe (1966)
and
A. p.
paraguayensis
Michaelsen (1905)
is based only on the degree of thickness of the atrophic distal tooth of the nedles. The great variability of this tooth, a characteristic of every atrophic structure, does not allow the specific distiction of
ghanensis
.
