Diagnosis. Specimens of
Heteroonops spinimanus
can be easily separated from all other Brazilian synanthropic species by the enlarged posterior projection on the male endites (see
PLATNICK & DUPÉRRE, 2009b:22
, figs 84-86), angular embolus and conductor (see
PLATNICK & DUPÉRRE, 2009b:22
, figs 87, 88) and the umbrella-shaped anterior receptaculum in the female genitalia (
Fig. 47
).
Description. Male and female, see
PLATNICK & DUPÉRRE (2009b:22
, figs 79-139).
Biology.
Heteroonops spinimanus
has been considered to be parthenogenetic by some authors (
SAARISTO, 2001
), resembling, in that regard,
T
.
stenaspis
. Even though it was originally described from
St. Vincent
, it’s currently known to have a Pantropical distribution. Although many populations of
H
.
spinimanus
may be parthenogenetic, apparently conspecific males have been collected together with females twice, in
Seychelles
Islands and in Florida (
PLATNICK & DUPÉRRÉ, 2009b
). All known specimens from
Brazil
are females, but the low number of samples prevents any claim on a parthenogenetic condition in Brazilian populations.
Distribution. According to
PLATNICK & DUPÉRRÉ (2009b)
, this species has a Pantropical distribution, but only two records in the South American countries were provided so far, from
Colombia
and
Venezuela
. Here the first Brazilian records of
H
.
spinimanus
are presented, from states of Bahia, São Paulo and Rio Grande do Sul (
Fig. 59
).
