Figures 167–170
Diagnosis. Vein MA with five main branches reaching wing margin (Fig. 168). Tegmina with five narrow and well-defined hyaline bands; hyaline bands with small black spots grouped together forming large asymmetrical spots (Fig. 168). Mesobasisternum triangular, anteriorly straight; lateral lobes anterolaterally convex, laterally and posteriorly straight, forming a posterolateral acuminate tip (Fig. 167E). Metabasisternum diamond-shaped, anteriorly convex with two triangular lateral protuberances; lateral lobes anterolaterally convex, laterally straight and posteriorly slightly concave, posterolaterally forming an angle of 120° (Fig. 167E). Left stridulatory with basal portion with teeth small, curved and total 13 teeth (Fig. 169A).
Description. Holotype Male.
Thorax. Mesobasisternum triangular, anteriorly straight; lateral lobes anterolaterally convex, laterally and posteriorly straight, forming a posterolateral acuminate tip (Fig. 167E). Metabasisternum diamond-shaped, anteriorly convex with two triangular lateral protuberances; lateral lobes anterolaterally convex, laterally straight and posteriorly slightly concave, posterolaterally forming an angle of 120° (Fig. 167E).
Wings. Vein MA with five main branches reaching wing margin (Fig. 168). Tegmina with five narrow and well-defined hyaline bands, overlapping the branches of the M and CuA veins; hyaline bands with small black spots grouped together forming large asymmetrical spots (Fig. 168). Left stridulatory file slightly curved; basal teeth small, curved and total 13 teeth (Fig. 169A). Total file length of 4 mm, greater vein width of 0.6 mm and a total of 82 teeth. Rigth stridulatory file slightly curved; basal and apical teeth small and curved (Fig. 169B). Total length file of 3.6 mm, widest vein of 0.4 mm and total of 80 teeth.
Legs. All femora ventrally with several small spines (Figs. 167F–H).
Abdomen. Cercus curved inwards, with the apex not expanded (Figs. 167I–K). Apex of cercus with curved convex projection and lateral spine, with a dark brown color (Fig. 167K). Stylus large and fusiform (Fig. 167I). Apex of stylus not exceeding half of cercus length, in ventral view (Fig. 167I).
Internal male genitalia. Not examined.
Coloration. Based on photos of preserved specimen (Fig. 167). Body dark brown. Eyes dark brown. Tegmina dark yellow. Hyaline bands with small black spots grouped together forming large asymmetrical spots.
Female: Unknown.
Etymology. The epithet is in apposition, tucurauna comes from the Brazilian Tupi indigenous language, tucura (katydid) + una (black) and means “black katydid”, in reference to the dark color of the dry specimens.
Distribution. Brazil: Rio de Janeiro (Fig. 170).
