Diagnosis: The new species can be easily differentiated from its congeners by the form of male cerci, bearing ten curved minute teeth on apex, and the internal medial process, dotted with small spines, and curved posteriorly.

Etymology: The specific name honours Sylvia Rivera (July 2, 1951 – February 19, 2002), a trans woman activist, who led the LGBTQI+ liberation movements that started in June of 1969, in the United States of America.

Description: Holotype male (2, 6A): Small, yellowish, probably green in life. Head ( Fig. 2B, C ): Fastigium of the frons triangular and projected; with a golden ocellus on middle; touching the fastigium of the vertex. Antennal sockets a little dilated near apex and at the beginning of the fastigium of the frons. Fastigium of the vertex hourglass shaped; globose at apex; with a small sulcus on middle that not reaches apex; crimson in the dorsal surface proximally. Thorax: Pronotum with several reddish punctations on pronotal disc. Pronotal disc ( Fig. 2C ) with brownish stains ( Fig. 2C ); anterior margin concave; posterior margin convex; furcal sulci triangular; enlarging from anterior to posterior region. Lateral lobes ( Fig. 2D ) smaller than pronotal disc, longer than wide; anterior margin straight with a depression on middle, posterior margin convex and semilunar; humeral sinus presenting an angle of ca. 85º. Tegmina shorter than hindwings ( Fig. 2A , 6A ); anal and costal margins parallel; Sc almost straight; R with 6 major branches that reaches costal margin; M long, following R in all extension; MP leaving M in the middle of tegmina; MA with one bifurcation at the apex; CuA very long almost straight, with ten bifurcations; A1 brown, stridulatory area with brownish stains ( Fig. 2F, G ). Mesobasisternum ( Fig. 2E ) elevated at the middle; anterior margin straight; lateral lobes small, triangular and obtuse, with the apices widely separated. Metabasisternum ( Fig. 2E ) triangular, elevated at the middle; anterior margin convex; lateral lobes demilune shaped, with posterior margin widely separat- ed. Abdomen: Tergite X projecting posteriorly; the middle curved ventrad, with small appendage, dorsal to cercus. Cercus ( Fig. 2H, I ) long; curved upwards and inwards; proximal prosses before middle of its length, bearing several minute spines; main branch with a deep sulcus; convoluted after middle; apex with a protuberance on ventro-lateral surface; apex with ten curved minute spines. Subgenital plate trapezoidal ( Fig. 2H, I ); posterior processes triangular, as long as large.

Type Material: Holotype male, ‘ DPTO ZOOL \ UF –PARANÁ’ ‘ S. José Pinhais — PR \ Brasil (Br277–Km54) \ 28.II.1985 \ C.I.I.F. (Luminosa)’, ‘ DZUP 366826 ’. Paratypes: One male, same data, except ‘ 13.III.1985 ’, ‘ DZUP 366825 ’; one male, same data, except ‘ 22.III.1985 ’, ‘ DZUP 366827 ’; and one male, same data, except ‘ 21.III.1985 ’ ‘ DZUP 366885 ’.

Measurements (mm): Holotype: BL: 11; TegL: 22; HW: 2.1; PrL: 2.2; PrH: 2.6; FLiii: 15; TLiii: 19; SPL: 1; CL: 4.1; SFL: 0.8; TN: 106.

Remarks: The new species is close to A. (Anallomes) antillarum Brunner von Wattenwyl , but it does not present other prolongations rather than the medial process of the cerci, whereas A. (Anall.) antillarum bears two more spines that are similar to prolongations. The apex of the cerci is rhomboid, as in A. (Anall.) richteri Cadena- Castañeda. The stature of the species resembles A. (Anall.) richteri, but it varies a lot in the Lanceolata group, that composes the Anallomes subgenera.
