( Figs 4A–L View FIGURE 4 ; 5G, H View FIGURE 5 )
Diagnosis: Male pygofer ( Fig. 4E, F View FIGURE 4 ), subtriangular, apex with a well-developed ventrocaudal subtriangular process. Anal tube ( Fig. 4E, F View FIGURE 4 ) with tergite X subtriangular, strongly expanded apically. Subgenital plates, in ventral view ( Fig. 4H View FIGURE 4 ), laterally compressed in median portion. Connective ( Fig. 4I View FIGURE 4 ) slightly longer than styles. Style ( Fig. 4I, J View FIGURE 4 ) with developed, subtriangular preapical lobe, directed dorsally. Aedeagus ( Fig. 4K, L View FIGURE 4 ) with shaft broad at base, strongly narrowing in apical three-quarters, slightly flattened dorsoventrally, bearing a pair of narrow, bifurcated lateral subapical processes.
Measurements. Males, 7.8–8.2 mm (n = 4).
Description. Head, in frontal view ( Fig. 4B View FIGURE 4 ), clypeus slightly expanded apically. Other external morphological characters, as in generic description in Gonçalves, Marques-Costa & Ale-Rocha (2012).
Coloration. Golden yellow ( Figs 4A–D View FIGURE 4 ; 5G, H View FIGURE 5 ) without distinct marks.
Male terminalia. Pygofer, in lateral view ( Fig. 4E, F View FIGURE 4 ), subtriangular, approximately 1.7 times longer than high; dorsal margin rounded; ventral margin slightly sinuous, with a well-developed ventrocaudal subtriangular apical process. Anal tube ( Fig. 4E, F View FIGURE 4 ) with tergite X subtriangular, strongly expanded apically. Subgenital plates, in lateral view ( Fig. 4E, G View FIGURE 4 ), slightly narrowed at median portion; in ventral view ( Fig. 4H View FIGURE 4 ), laterally compressed in median portion; ventral surface with numerous microsetae scattered throughout its length; apex of each plate subtruncate. Connective ( Fig. 4I View FIGURE 4 ) slightly longer than styles. Style ( Fig. 4I, J View FIGURE 4 ) with apodeme bilobed, with dorsal projection subtriangular and ventral projection narrow, produced anterad; apophysis sinuous; preapical lobe developed, subtriangular, and directed dorsally; few microsetae beneath apical hook; dentiform process at hook base, apical hook well-developed, strongly curved ventrally, apex acute. Aedeagus ( Fig. 4K, L View FIGURE 4 ) with shaft broad at base, narrowing strongly in apical three-quarters, slightly flattened dorsoventrally; bearing a pair of narrow, bifurcated lateral subapical processes, with branches of similar length, dorsal branch directed laterally and slightly curved ventrally, ventral branch strongly directed ventrally, acute apices.
Female. Unknown.
Distribution. Brazil: Amazonas, Roraima.
Etymology. The species name alludes to branched processes of aedeagus, ( Fig. 4K, L View FIGURE 4 ).

Notes. Placoscopana birama sp. nov. can be distinguished from P. nigrilinea by the following characteristics: In P. birama sp. nov. the subgenital plates lack setae on apical portion of dorsal surface ( Fig. 4G, H View FIGURE 4 ), while in P. nigrilinea , these setae are present (Gonçalves et al. 2012: figs 6, 7). The connective is longer than styles in P. birama sp. nov. ( Fig. 4I View FIGURE 4 ), while in P. nigrilinea , it is shorter (Gonçalves et al.: 2012 fig. 9). The preapical lobe of style is well-developed in P. birama sp. nov. ( Fig. 4I, J View FIGURE 4 ), whereas it is absent in P. nigrilinea (Gonçalves et al. 2012: figs 8, 9). Finally, the aedeagus in P. birama sp. nov. has a narrow shaft with a smooth ventral margin and a pair of subapical processes ( Fig. 4K, L View FIGURE 4 ), while in P. nigrilinea , the shaft is robust with spined ventral margins and lacks processes (Gonçalves et al. 2012: figs 10, 11).
