Anaulacomera arlindoi View in CoL sp. n. Fianco, Faria & Cadena-Castañeda
Fig. 3 View FIGURE 3
Diagnosis: Fastigium of the vertex originating from two oblique and reddish crest; fastigium of the frons with an ocellus; tergite X with two lateral expansions as long as half of the length of the tergite; main branch of the cerci lanceolate and flattened, moderately curved to the median region, first ramification not flattened, bent over itself, with a curved spine on the apex.
Etymology: The specific epithet honors Arlindo Fianco, grandfather of the first author. He was an activist fighting against the abusive use of pesticides in crops of southwestern Paraná state, with a life deeply connected to environmental preservation.
Description: Holotype male, medium to small-sized, greenish-yellowish, green in vivo ( Fig. 3A View FIGURE 3 ). Head: fastigium of the vertex not touching the frons, originating from two oblique and reddish crest of the same width as pedicel ( Fig. 3C View FIGURE 3 ); fastigium of the frons with ocellus. Thorax: Pronotum: Pronotal disc not compressed between major prozone and metazone; posterior margin convex, anterior margin concave; furcal sulci forming an inverted v-like structure. Lateral lobes smaller than pronotal disc, as long as wide; anterior margin curved, posterior margin convex and semi-circular; humeral sinus presenting an angle of ca. 60º ( Fig. 3B View FIGURE 3 ). Wings ( Fig. 3J View FIGURE 3 ): Tegmina with anal and costal margins parallel; ScA short, almost straight; three veins leaving ScP; RP vein beginning after the middle of the tegmina, without any branch; RA ending in the costal area, with two veins leaving it; A1 vein black in dorsal view with 86 teeth that become smaller towards the anal area ( Fig. 3H, I View FIGURE 3 ); MA without any branch; none closed-cell between RA and RP; five closed cells between R and CuA. Sternum: anterior margin of the mesosternum concave; lateral lobes small and triangular; its posterior margin with one-third of the length of the lateral margin; lateral lobes without overlapping in the posterior margin. Metasternum triangular, with a straight anterior margin, equilateral; lateral lobes demilune shaped, not touching in the posterior margin. Abdomen: Tergite X ( Fig. 3E, F View FIGURE 3 ) quite large, posterior margin concave, with two lateral expansions, as long as half of the length of the tergite, moderately curved downwards. Cercus forked ( Fig. 3F, G View FIGURE 3 ); the main branch lanceolate and flattened, apex acuminated in a brownish spine, moderately curved to the median region; ramification not flattened, bent over itself, with a curved spine on apex. Subgenital plate ( Fig. 3D View FIGURE 3 ) longer than wide; median keel absent; posterior processes obtuse, wider than long.
Coloration: body coloration green ( Fig. 3A View FIGURE 3 ), vertex light yellow with a yellow stripe from the eye in direction to pronotum; fastigium of the frons light yellow; ocellus gold; frons lighter than vertex; eyes reddish ( Fig. 3B–C View FIGURE 3 ); pronotum yellow with few reddish punctations, in the live specimens green with reddish punctations ( Fig. 3A–B View FIGURE 3 ). Stridulatory area of left tegmen yellowish on proximal and greenish on distal area, brown at the middle ( Fig. 3H View FIGURE 3 ); abdomen mostly yellowish, green in live specimens.

Comparison: This new species conforms to the characteristics of the Lanceolata Group, due to the structure of the male’s cerci, but differs from all other species of the Group, except A. curvata , by the tenth tergite modified in two lobes, which is characteristic of the Latifolia Group, but in the males of A. arlindoi sp. n. and A. curvata they differ in the structure of the cerci that in the Latifolia are acuminated. Thus, the diagnosis of the Anaulacomera (Anallomes) group is extended, which may include species with the tenth tergite modified or not, but always with cerci branching before half of its length, and main branch generally lanceolate and flattened. A. arlindoi sp. n. is the closest species to A. curvata , differing from this by the breadth of the main branch of the cerci, that is wider and more flattened in the new species, the size of the medial branch of the cerci, that is bigger in the new species, and in the morphology of subgenital plate, that does not possess an evident posterior process. The new species also resembles A. antillarum , in cerci shape, differing because the new species has the apex dilated of the inner branch and with an additional spine at the apex, in contrast to A. antillarum , which has the inner branch of the cerci triangular and without additional spines.
Anaulacomera (Anallomes) distribution: the group is distributed throughout the Neotropical Region, including the Antilles ( A. antillarum ), the eastern portion of the Andes ( A. dentata , A. lanceolata , A. maculata , A. richteri , A. sulcata and A. valentinae further north; A. sulcata also occurs more southwards on the middle of the mountain range, together with A. nodulosa ). This latter species, A. nodulosa , also occurs in the Cerrado (Chacoan dominion). Anaulacomera arlindoi sp. n. occurs in the Atlantic Forest (Parana dominion), just like A. curvata , A. intermedia and A. sylviae , with A. arlindoi sp. n. presenting the southernmost records for the group ( Fig. 4 View FIGURE 4 ).
