Epitrigoniulus cruentatus ( Brölemann, 1903) ( Figs. 1D , 7 A-B)

Descriptive notes: See Brölemann (1903: 250, figs. 5-9).

Identification: According to the description made by Brölemann (1903), males of E. cruentatus can be recognized by coxae of the anterior gonopods separated by subtriangular sternum ( Fig. 7A ); and telopodites subtriangular ( Brölemann, 1903: fig. 5). Telopodites of the posterior gonopods rounded and expanded distad; and with notches along the mesal margin ( Brölemann, 1903: figs. 6-8; Fig. 7B ).

Distribution: Epitrigoniulus cruentatus occurs in the Indo-Malayan region ( Brölemann, 1903; Schubart, 1947). In Brazil, the species has been recorded only in the Amazonian region ( Brölemann, 1903, 1909).
