Capanema pocanga Mendes & Rafael View in CoL sp. nov.

Figures 2 View FIGURE 2 , 6–10 View FIGURE 6 View FIGURE 7 View FIGURE 8 View FIGURE 9 View FIGURE 10

Diagnosis. Tegmina with distal region concave ( Fig. 7 View FIGURE 7 ). Fourth branch of vein CuA and vein MP connected by transverse vein ( Fig. 7 View FIGURE 7 ). First branch of vein CuA associated with hyaline regions with dark bands lined up ( Fig. 7 View FIGURE 7 ). Lateral lobes of mesobasisternum forming an acute posterolateral angle of 50° straight ( Fig. 6E View FIGURE 6 ). Apex of cercus with rounded expansion and small spiny ( Fig. 6K View FIGURE 6 ).

Description. Holotype Male.

Thorax. Lateral lobes of mesobasisternum anterolaterally, laterally and posteriorly straight, forming an acute posterolateral angle of 50° straight ( Fig. 6E View FIGURE 6 ). Metabasisternum triangular, anteriorly straight and laterally with two small convex projections ( Fig. 6E View FIGURE 6 ).

Wings. Tegmina wide, posterior margin and distal region convex ( Fig. 7 View FIGURE 7 ). MA with two branches ( Fig. 7 View FIGURE 7 ).

First branch of the CuA vein with hyaline region associated with small circular patches grouped, forming black stripes aligned laterally on both sides of the branch; other branches of CuA and MP with narrow hyaline region also with several small circular spots, forming asymmetrical spots ( Fig. 7 View FIGURE 7 ). Fourth branch of vein CuA and vein MP connected by transverse vein ( Fig. 7 View FIGURE 7 ). Vein CuA not connected with vein MP ( Fig. 7 View FIGURE 7 ).

Total length of left stridulatory file 2 mm, greater vein width of 0.4 mm and a total of 49 teeth. Right stridulatory file slightly curved, with apex region concave ( Fig. 8B View FIGURE 8 ). Total length file of 1.8 mm, widest vein of 0.2 mm and total of 51 teeth. Teeth rectangular, narrow and far apart; teeth basal minor; in basal half larger and more widely spaced ( Figs. 8A–B View FIGURE 8 ).

Abdomen. Apex of cercus with rounded expansion and small spiny, both with dark brown coloration ( Fig. 6K View FIGURE 6 ).

Internal male genitalia. Ejaculatory vesicle reniform ( Figs. 9A–D View FIGURE 9 ). Upper fold of ventral lobe large, elongated, asymetrical and not connected ( Figs. 9A–B View FIGURE 9 ). Titillator process large and asymetrical ( Figs. 9A–D View FIGURE 9 ). Lower fold of ventral lobe large, posteriorly convex and exceeding the dorsal lobe ( Figs. 9A–B View FIGURE 9 ). Dorsal lobe anteriorly with median convex projection, laterally with two long and acuminated projections, posteriorly convex ( Figs. 9A–D View FIGURE 9 ). Dorsal fold elongated and narrow ( Figs. 9C–D View FIGURE 9 ).

Coloration. Based on photos of preserved specimen ( Fig. 6 View FIGURE 6 ). Body yellowish-green. Eyes brown.

Female: unknown.

Etymology. The epithet is in apposition, pocanga [pokanga] comes from the Brazilian indigenous language Tupi and means “which is rare”, in reference to the rarity of this species.
