Diagnosis.

Pararhagadochir can be distinguished from other Archembiidae by having the anterior margin of Sm strongly concave, 10Lp1 apically forked with the internal tip (hook) and the external tip (flat lobe) separated, with both tips always shorter than the width of 10L. It can be differentiated by the presence of a sclerotized node between 10L and the base of LC1 and 10Rp2 with more than one longitudinal laminate keel ( Szumik 2004).

Composition and distribution.

The genus is known from Colombia to Argentina and includes 16 species ( Szumik 2004): Pararhagadochir trinitatis (de Saussure, 1896) from Trinidad and Venezuela, P. surinamensis (Ross, 1944) from Surinam, P. balteata Ross, 1972, P. bicingillata (Enderlein, 1909), P. castaneus Salvatierra, 2020, P. christae Ross, 1972, P. minuta Ross, 2001, P. noronhensis Costa-Pinto et al., 2021 from Brazil (see Catalog), P. flavicollis (Enderlein, 1909), P. tenuis (Enderlein, 1909) from Bolivia; P. confusa Ross, 1944, P. schadei Ross, 1944, from Paraguay and Argentina; P. birabeni (Navas, 1918), P. pallida Ross, 2001, P. trachelia (Navas, 1915) from Argentina and P. picchua Ross, 2001 from Peru. Recently, P. confusa was also found in Brazil ( Teixeira et al. 2018a). In addition, three new species from Brazil are described below and new locality records for the species P. balteata , P. bicingillata , P. christae , and P. confusa are added; the number of species of Pararhagadochir present in Brazil increases to ten.

Distribution.

South America.

Relationships.

Pararhagadochir is clearly a monophyletic genus ( Szumik et al. 2008, 2019), supported by several synapomorphies (detailed in the diagnosis of the genus). The sister group is a genus from East Africa, Chirembia .
