Brignolia dasysterna PLATNICK et al., 2011:32 , figs 95-141. Male holotype and female allotype taken in Berlese samples of young hammock forest litter at Deering Estate Park, SW 167 th St. and SW 72 nd Ave., South Miami, Dade Co., Florida, USA, 1.VI–25.VIII.1986, J. & S. Peck leg., in AMNH 37534 , PBI_ OON 1270 , not examined.

Brignolia cubana : FREITAS et al., 2013:9-10, 15 (misidentification).

Diagnosis. Brignolia dasysterna can be easily separated from autochthone Neotropical oonopids and from B. parumpunctata by the absence of ventral directed protrusion situated medially on the clypeus (see PLATNICK et al., 2011, fig. 96), modified setae on the male sternum ( Fig. 3 ), male palp with small protrusion on the palpal bulb ( Figs 5, 6 ; PLATNICK et al., 2011, figs 103-108) and females by the low protrusion situated between the epigastric furrow and the groove connecting the posterior spiracles ( Fig. 4 ).

Description. Male and female, see PLATNICK et al., 2011:32, figs 95-141.

Distribution. This species was recently described by PLATNICK et al. (2011) as being restrict to southern Florida, USA. It is recorded here to occur in at least four states of north and northeast Brazil ( Fig. 58 ), where it may have been introduced earlier than in the USA. FREITAS et al. (2013) found a large population of Brignolia dasysterna (sub Brignolia cubana ) in Fernando de Noronha archipelago.
