R. virescens resembles R. bittencourti by the male external apophysis of coxa IV without basal tubercle (Fig. 4) and penis with ventral plate cordiform and stylus without ventral process (Fig. 5). It is distinguished from R. bittencourti by the presence of small tubercles of similar size on dorsal part of male patella and tibia IV (Fig. 3 A,B) and from R. garrincha sp.n. by the absence of ventral process of stylus. Morphological variation. The study of 125 specimens of Roeweria virescens showed a large morphological variation, mainly in orientation and shape of armature of area III, ocularium and number and arrangement of tubercles on dorsal scutum. At first, the observation of only few specimens (see Fig. 4 for most remarkable forms) led us to conclude that the diversity of what was known as R. virescens was impressively high for a small distribution area. However, the examination of large series revealed intermediate forms from the same sites, making it impossible to recognize two or more species using the combination of these characteristics. Thus, we conclude that this species is highly polymorphic. The main variable features are: armature of ocularium with two high (longer than ocularium height) and pointed apophyses (Fig. 4 a, e) or with blunt and not so high apophyses (Fig. 4 b���d); anterior pair of tubercles on ocularium present (Fig. 4 A, E) or absent (Fig. 4 B���D); area III with armature straight (Fig. 4 a,c,d,e) or curved (Fig. 4 B); apophyses of area III joined apically (Fig. 4 A,B) or separated and parallel (Fig. 4 C���E); and large amount of tubercles on dorsal scutum (areas I���IV) concentrated mainly on median region of areas I���II, ranging from nearly 50 (Fig. 4 C,E) to more than 100, distributed homogeneously and covering all dorsal scutum (Fig. 4 A,B,D). The morphology of penis shows variation on number of apical setae present, which may be three (Fig. 5 B,E,H,K) or rarely four, apex of stylus (more elongated in Fig. 5 H,I than Fig. 5 K,L) and shape of ventral plate, always cordiform, but rectangular apical part ranging from narrow (Fig. 5 D,E, for instance) to a little wider (Fig. 5 A,B).
