Figures 1A , 4 , 6C Diagnosis: Anaulacomera ( Anaulacomera ) rubrovittata sp. n. can be differentiated from its congeners by the combination of the following characters: tegmina much shorter than hindwings, 1.5x longer than body; bearing a red stripe on abdominal tergites; cercus tapering gradually, with principal curvature in the last third. Etymology: The specific epithet derived from Latin (rŭber = red; vittātus = stripe), in allusion to the presence of a red stripe on dorsally of abdominal tergites. Description: Holotype male ( Fig. 4 , 6C ): Small, yellowish with several reddish punctations, probably green in life, bearing a reddish stripe in dorsal tergites of abdomen. Head ( Fig. 4B, C ): Fastigium of the frons triangular, longer than wide; apex in a rhomboid; with a golden and large ocellus on middle. Antennal sockets dilated at base and apex. Fastigium of the vertex triangular; globose at apex; with none sulcus on middle. Thorax: Pronotum plain colour. Pronotal disc ( Fig. 4C ) with anterior almost straight and posterior margin convex; furcal sulci bell-shaped; wider in the anterior region. Lateral lobes ( Fig. 4D ) smaller than pronotal disc, longer than wide; anterior margin straight; posterior margin convex, demilune shaped; humeral sinus presenting an angle of ca. 80º. Tegmina ( Fig. 4A , 6C ) much shorter than hindwings; anal and costal margins parallel; Sc almost straight; R without bifurcations; M long, following R in all extension; MP leaving M in the middle of tegmina; MA with two bifurcations; CuA almost straight; stridulatory area yellowish, with a brown spot on begging and end of A1 ( Fig. 4F, G ). Mesobasisternum (Fig. E) not elevated on middle; anterior margin concave; lateral lobes small, demilune shaped, distant in the posterior margin. Metabasisternum ( Fig. 4E ) triangular, moderately elevated on middle; anterior margin convex; lateral lobes demilune shaped, distant in the posterior margin. Abdomen: With a red stripe on dorsal surface of all tergites. Posterior margin of tergite X straight. Epiproct rectangular, apical part with a deep groove on middle, as large as long. Cercus ( Fig. 4H, I ) long; curved, principal curvature in the last third; ending in a spine-like process. Subgenital plate ( Fig. 4H, I ) trapezoidal; moderately long; posterior processes rhomboid, as large as long. Type Material: Holotype male , ‘ DPTO ZOOL \ UF –PARANÁ’ ‘ B.

Scale bars: A = 1 cm; B–F, H–I = 2 mm; G = 1 mm. Remarks: Anaulacomera ( Anaulacomera ) rubrovittata sp. n. belongs to the Uncinata species group, since the male cercus is curved sickle-like, and can be differentiated from all species of the group distinct red stripe on tergites of abdomen, the small body length and the tegmina much smaller than hindwings. From the eight species of the Uncinata group, this new species is probably closer to A. ( Anaul .) bovicula Rehn and A. ( Anaul .) surdastra Piza, recognized by the not so curved cerci as in A. ( Anaul .) bovicula and a more curved cerci than A. ( Anaul .) surdastra . Additionally, the cercal thickness decreases gradually from base to apex, whereas in A. ( Anaul .) surdastra it abruptly tapers at the apex, and in A. ( Anaul .) bovicula it abruptly tapers at the base. The subgenital plate is very similar to A . ( Anaul .) acutangulata Márquez Mayaudón, long and curved upwards, but in the new species it is wider and the apex is not expanded. On the other hand, in all other species the subgenital plate is small, and does not curve upwards, and as in A. ( Anaul .) rubrovittata sp. n. it does not widen apically.
