 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).
