Abstract

<i>Anaulacomera</i> (<i>Anaulacomera</i>) <i>rubrovittata</i> sp. n. <p>Figures 1A, 4, 6C</p> <p> <b>Diagnosis:</b> <i>Anaulacomera</i> (<i>Anaulacomera</i>) <i>rubrovittata</i> <b>sp. n.</b> 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.</p> <p> <b>Etymology:</b> The specific epithet derived from Latin (rŭber = red; vittātus = stripe), in allusion to the presence of a red stripe on dorsally of abdominal tergites.</p> <p> <b>Description: Holotype male (Fig. 4, 6C):</b> Small, yellowish with several reddish punctations, probably green in life, bearing a reddish stripe in dorsal tergites of abdomen. <b>Head (Fig. 4B, C):</b> 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. <b>Thorax:</b> 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 <i>ca.</i> 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. <b>Abdomen:</b> 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.</p> <p> <b>Type Material:</b> <i>Holotype male</i>, ‘ DPTO ZOOL \ UF –PARANÁ’ ‘ B. Guandú –ES Brasil \ 4–7–X–1970 \ Tadeu & C. Elias col’ ‘ DZUP 366671 ’. <b>Paratype</b>: One male, ‘GUARAPARI E. Santo \ Brasil \ IX–1960 \ M.

From the eight species of the Uncinata group, this new species is probably closer to <i>A.</i> (<i>Anaul</i>.) <i>bovicula</i> Rehn and <i>A.</i> (<i>Anaul</i>.) <i>surdastra</i> Piza, recognized by the not so curved cerci as in <i>A.</i> (<i>Anaul</i>.) <i>bovicula</i> and a more curved cerci than <i>A.</i> (<i>Anaul</i>.) <i>surdastra</i>. Additionally, the cercal thickness decreases gradually from base to apex, whereas in <i>A.</i> (<i>Anaul</i>.) <i>surdastra</i> it abruptly tapers at the apex, and in <i>A.</i> (<i>Anaul</i>.) <i>bovicula</i> it abruptly tapers at the base. The subgenital plate is very similar to <i>A</i>. (<i>Anaul</i>.) <i>acutangulata</i> 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 <i>A.</i> (<i>Anaul</i>.) <i>rubrovittata</i> <b>sp. n.</b> it does not widen apically.</p>Published as part of <i>Fianco, Marcos, 2021, Nine new species of the Anaulacomerina subtribe of katydids (Orthoptera Tettigoniidae: Phaneropterinae: Phaneropterini) from Brazil, pp. 33-54 in Zootaxa 4952 (1)</i> on pages 39-40, DOI: 10.11646/zootaxa.4952.1.2, <a href="http://zenodo.org/record/4671657">http://zenodo.org/record/4671657</a&gt
