( Figs. 1 View FIGURE 1 , 25–42 View FIGURES 25–28 View FIGURES 29–31 View FIGURES 32–37 View FIGURES 38–42 )

Etymology. The epithet refers to the diverging apex of the paramere bifurcation. Latin: divergere, turned to different directions.

Holotype. Male, here designated. BRAZIL, Pará: Jacareacanga (-6.22, -57.80), XII-1968, M. Alvarenga. Deposited in: CEIOC ( Figs. 25–31 View FIGURES 25–28 View FIGURES 29–31 )

Paratype. Male, same data as the holotype. Deposited in: CEIOC .

Diagnosis. Body convex ventrally ( Fig. 27 View FIGURES 25–28 ); labium not attaining the posterior margin of metasternum; metasternal carina narrow; peritremal disc attaining the lateral third of metapleura ( Fig. 31 View FIGURES 29–31 ); pygophore with lateral margins sinuous ( Fig. 32 View FIGURES 32–37 ); superior layer of ventral rim forming a v-shaped posterior projection ( Fig. 37 View FIGURES 32–37 ); paramere dish-shaped process large and deep; apical bifurcation of paramere diverging ( Figs. 40–42 View FIGURES 38–42 ).

Description. Body ventrally convex ( Fig. 27 View FIGURES 25–28 ). Punctures black, minute on head, evenly distributed on pronotum and scutellum. Head 1.6 times wider than long; labium not attaining the posterior margin of metasternum. Thorax. Pronotal anterior margin shallowly concave, anterolateral angles in round projection, humeral angles reddish ( Fig. 29 View FIGURES 29–31 ). Scutellar apex acute ( Fig. 25 View FIGURES 25–28 ). Metasternal carina narrow. Peritremal disc sinuous, attaining the lateral third of metapleura ( Fig. 31 View FIGURES 29–31 ). Abdomen. Connexival segments dark brown, paler on middle ( Fig. 25 View FIGURES 25–28 ). Urosternites the same color of the dorsal surface; spiracles black, contrasting with the surrounding surface ( Fig. 26 View FIGURES 25–28 ).

Male. Measurements (n=2): Total length 14.10 ± 0.14 (14.00–14.20); width of abdomen 8.65 ± 0.46 (8.30– 9.00); head length 1.85 ± 0.07 (1.80–1.90); width 3.00 ± 0.14 (2.90–3.10); pronotum length 3.55 ± 0.07 (3.50–3.60); width 7.85 ± 0.07 (7.80–7.90); scutellum length 5.75 ± 0.07 (5.70–5.80); width 4.85 ± 0.21 (4.70–5.00); length of antennomeres: I 0.85 ± 0.07 (0.80–0.90), II 0.95 ± 0.07 (0.90–1.00), III 1.35 ± 0.07 (1.30–1.40), IV 2.05 ± 0.07 (2.00–2.10); V (n=1) 2.60 ± 0.00 (2.60); length of labiomeres: I 1.05 ± 0.07 (1.00–1.10), Int 0.10 ± 0.00 (0.10), II 1.50 ± 0.00 (1.50), III 1.35 ± 0.07 (1.30–1.40), IV 1.00 ± 0.00 (1.00).

Genitalia ( Figs. 32–42 View FIGURES 32–37 View FIGURES 38–42 ). Pygophore. Lateral margins sinuous ( Fig. 32 View FIGURES 32–37 ); dorsal wall length on midline twice the segment X length ( Fig. 32 View FIGURES 32–37 ); dorsal rim roundly concave over segment X ( Figs. 32–34 View FIGURES 32–37 ); posterolateral angles broadly excavated ( Figs. 32–34 View FIGURES 32–37 ); ventral rim with sparse setae, middle third concave, superior layer forming a v-shaped posterior projection ( Fig. 37 View FIGURES 32–37 ). Segment X with lateral short pale setae ( Figs. 32–34 View FIGURES 32–37 ). Parameres laterally sinuous, dish-shaped process large and deep; apical bifurcation of paramere diverging, branches subequal in length, crossing each other ( Figs. 40–42 View FIGURES 38–42 ). Phallus strongly sclerotized; proximal thecal width almost ten times lesser the maximum thecal width in lateral view ( Fig. 38 View FIGURES 38–42 , th); dorsal process of endosoma more than twice longer than the rigid part of the ventral process of endosoma ( Fig. 38 View FIGURES 38–42 , dpe, vpe); apical lobes of the dorsal process of endosoma large, angled ventrally, and much longer than the lobes of the ventral process of theca ( Figs. 38, 39 View FIGURES 38–42 , dpe, vpt); ventral process of endosoma ruptured, making it impossible to determine its length.
