Anaulacomera (Oecella) marshae Fianco 2021, sp. n.

Abstract

<i>Anaulacomera</i> (<i>Oecella</i>) <i>marshae</i> sp. n. <p>Figures 1B, 7, 12A</p> <p> <b>Diagnosis:</b> <i>Anaulacomera marshae</i> <b>sp. n.</b> is promptly distinguished from all other members of <i>A.</i> (<i>Oecella</i>) by the male cerci, which is thick, robust, and with apex expanded giving it the resemblance of an oven glove.</p> <p> <b>Etymology:</b> The specific name honours Marsha P. Johnson (August 24, 1945 – July 6, 1992), a black trans woman activist, who led the LGBTQI+ liberation movements that started in June of 1969, in the United States of America, and then spread across the world.</p> <p> <b>Description: Holotype male (Fig. 7, 12A):</b> Medium sized, yellowish, probably green in life (Fig. 7A). <b>Head (Fig. 7B, C):</b> fastigium of the frons triangular, apex rhomboid, with an ocellus on middle; antennal sockets dilatated in ventrolateral margin; fastigium of the vertex conical, dilatated at apex, with a sulcus on middle that does not reach the apex. <b>Thorax:</b> Pronotum with several purplish dots. Pronotal disc (Fig. 7C) with posterior margin convex; anterior margin concave; furcal sulci flattened; anterior and posterior margin enlarged when compared to middle region. Lateral lobes (Fig. 7D) smaller than pronotal disc, longer than wide; anterior margin straight, posterior margin convex and semilunar; humeral sinus presenting an angle of <i>ca.</i> 85º. Tegmina (Fig. 7A, 12A) shorter than hindwings; anal and costal margins almost parallel; R with seven bifurcations that reach costal margin; M long, following R in all extension; MA with one bifurcation, anterior branch not reaching the tegmen margin, posterior branch reaching the posterior border; MP with one bifurcation; CuA almost straight, with two bifurcations; stridulatory area of left tegmen whitish in proximal area, brownish in middle area, and plain tegmen colour in distal area greyish in the centre (Fig. 7F, G). Mesobasisternum (Fig. 7E) with anterior margin almost straight; lateral lobes small, with rhomboid apex, without overlapping in the posterior margin. Metabasisternum (Fig. 7E) triangular, with a straight anterior margin; lateral lobes demilune shaped, almost touching in the posterior margin. Mid and hind leg with purplish punctations. <b>Abdomen:</b> with small and spaced purplish punctuations. Tergite X large, concave and in a downwards triangular projection in posterior margin. Epiproct quite long, curving anteriorly; apex bifid, branches laterally directed; middle of bifurcation globose with several setae. Cercus (Fig. 7H, I) robust, similar to an oven glove; with one bifurcation, the ventral triangular and more sclerotized at apex, the dorsal oblong. Subgenital plate (Fig 7H, I) longer than wide, emarginated posteriorly, with two acute projections separated by a deep U-shaped sinus.</p> <p> <b>Type Material:</b> <i>Holotype male</i>, ‘ S. José Pinhais — PR \ Brasil (Br277–Km54) \ 23.III. 1985 \ C.I.I.P (Luminosa)’ ‘DPTO ZOOL \ UF –PARANÁ’, ‘ DZUP 366866 ’. <b>Paratypes</b>: One male, same data, except ‘ 10.IV.1985 ’, ‘ DZUP 366881 ’, and one male ‘ P. Grossa \ V. Villela \ G. Chuva \ 9–67 \\ ♂ \ 7140 \\ Coleção \ F. Justus’ ‘ DZUP 366576 ’.</p> <p> <b>Measurements (mm):</b> <i>Holotype</i>: BL: 18.2; TegL: 3.6; HW: 2.7; PrL: 4; PrH: 3.8; FLiii: 19.2; TLiii: 22.5; SPL: 3.9; CL: 3.2; SFL: 1.24; TN: 44.</p> <p> <b>Remarks:</b> Within the subgenera, <i>A.</i> (<i>O.</i>) <i>marshae</i> <b>sp. n.</b> cannot be placed in any group, remaining with <i>A.</i> (<i>O.</i>) <i>confusa</i> Piza, <i>A.</i> (<i>O.</i>) <i>lingulata</i> Piza, and <i>A.</i> (<i>O.</i>) <i>maculifemora</i> Piza. These species are closely related, and may form a separated group from the other two in the subgenera, Furcata and Juanchoi species group. Within these three species, the most closely related is <i>A.</i> (<i>O.</i>) <i>maculifemora</i>. The new species possesses a medial prosses of the cercus after the middle, as the other ungrouped species of <i>A.</i> (<i>Oecella</i>). The new species can be differentiated from these species by the form of male cerci, which is thicker in the new species and thinner in the remaining, additionally, the apex of the cerci is expanded, and this does not occur in the aforementioned species.</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 43-45, DOI: 10.11646/zootaxa.4952.1.2, <a href="http://zenodo.org/record/4671657">http://zenodo.org/record/4671657</a&gt
