Tegmina with whitish punctuations slightly below and along ScP+R.   Etymology:The specific epithet honors Angelina Fianco, grandmother of the first author. The holotypewas collected at light in her house.   Description: Holotypemale, medium to big sized, greenish-yellowish, green in vivo ( Fig. 5A). Head:Eyes protuse, fastigium of the vertex elevated, slightly expanded on apex ( Fig. 5C). Thorax:pronotum light green. Pronotal disc not compressed between prozona and metazona; posterior margin convex, anterior margin almost straight; furcal sulci bell-shaped. Lateral lobes smaller than pronotal disc, longer than wide; anterior margin straight, posterior margin convex and semi-circular; humeral sinus presenting an angle of ca.90º, delineated in black ( Fig. 5B). Wings( Fig. 5H): Tegmina light green ( Fig. 5A). Anal and costal margins almost parallel; ScA long, ending almost at the middle of the tegmina; ScP with five branching veins, leaving after the end of ScA; RP vein beginning before the middle of the tegmina, without any branch; RA ending in the costal area; A1 vein yellow in dorsal view with 72 teeth that becomes smaller towards the costal area, on both tegmina; with dark grey punctuation above M; in tegmina, punctuations slightly below ScP+R, along with the extension of this vein. Stridulatory area of left tegmen whitish in the centre, and light grey in direction to apex ( Fig. 5F). Sternum: anterior margin of mesosternum concave; lateral lobes small and triangular; its posterior margin with ca. 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. Tibia I with general light green colour with exception of tympanum expansion and tibia apex that is purplish; Femur I, II and III and Tibia II and III light-green with light brown stains. Abdomen:general brownish colour, light-green in live specimens. Tergite X is quite large, posterior margin concave. Cercus ( Fig. 5D–E) with two ramifications, one just before and one just after the middle, an additional expansion not forming a branch in the at the same time of the first ramification; first ramification median, curving upwards in right angle, the angle very broad, apex rhomboid; second ramification ventral, almost straight, length smaller than half of the first ramification, apex rhomboid; main branch of cercus longer than first and second ramifications, curved to the medial region, apex pointed, very sclerotized. Subgenital plate ( Fig. 5D) as long as wide; median keel absent; posterior processes obtuse, with a straight margin between them, arising from a keel that starts at posterior third of subgenital plate length.  Female paratype( Fig. 6):Larger than males. Morphological details of head and pronotum as in males. General coloration as in males. Stridulatory area green with two black spots, one at the proximal and one at the distal area ( Fig. 6B). Right-wing with three stridulatory veins of conical teeth. Tergite X not expanded. Ovipositor ( Fig. 6D) greenish, slightly curved up, a little longer than twice as pronotum; lateral margins of dorsal and ventral valves outlined in brown, with small serrulations. Cerci conical, smaller than subgenital plate. Subgenital plate ( Fig. 6C) almost square, base wrinkled, with two lateral concave appendages, not longer than half of the length of the subgenital plate.  Coloration:General coloration green; vertex light green; vertex of the frons light green, frons lighter; eyes brown ( Fig. 5B–C); gena and frons almost white, with light green stains ( Fig. 5B).   Type Material:   Holotypemalelabelled “ BR, PR, Renascença/Fazenda Céu Azul/  03.II.2020/Attracted to the light of a house/ Fianco, M.col.”. deposited at Museu Nacionaldo Rio de Janeiro( MNRJ), Rio de Janeiro, Brazil.   Paratypes: 1 malelabelled “ BR, PR, Foz do Iguaçu/ Parque Nacional do Iguaçu/  12–14.IX.2019/ Coletaativa diurna/ Fianco, M.col”, and  1 femalelabelled “ BR, PR, Foz do Iguaçu/Parque Nacional do Iguaçu/  12–14.IX.2019/Coleta ativa diurna/ Fianco, M.col” deposited at “Coleção Entomológica Padre Jesus Santiago Moure” ( DZUP), Curitiba, Brazil.   Measurements:  Holotype: BL: 16; TegL: 32; HW: 3; PrL: 5.1; PrH: 3; FLiii: 21; TLiii: 24; SPL: 3; CL: 3. Male paratype: BL: 16.8; TegL: 29.8; HW: 3; PrL: 4.6; PrH: 2.8; FLiii: 20.5; TLiii: 23.1; SPL: 2.6; CL: 3.3; SFL: 1.4; TN: 74. Female paratype: BL: 20.5; TegL: 32.4; HW: 3.4; PrL: 5.9; PrH: 3.3; FiiiL: 19.8; TiiiL: 23.1; SPL: 2.3; OL: 12.2.   FIGURE 5.  Anaulacomera angelinae  sp. n.A: Male habitus, holotype; B: Head and pronotum, lateral view; C: Head, dorsal view; D: Cercus and subgenital plate, ventral view; E: Cerci, dorsal view; F: Stridulatory area of left tegmen; G: Stridulatory file, H: Tegmen. Scale bars (in mm): B = 1.5; C = 0.7; D and E = 1.5; F = 3; G = 0.5   FIGURE 6.  Anaulacomera angelinae  sp. n.A: Female habitus, Paratype; B: Stridulatory area; C: Subgenital plate; D: Ovipositor. Scale bars (in mm): B = 3; C = 0.5; D = 5.  Comparison:The presence of two ramifications on male’s cerci, one before the middle of the cerci, could support the decision of placing this new species within the Poculigera Group (  Anaulacomera(Munticercora)). But, differing from the species of the Poculigera Group,  A. angelinae  sp. n.presents the main ramification of the cerci resembling a curved knife, besides that the second ramification of the cercus appears on its first half brings as in  Anaulacomera trispinata Fianco, Faria & Cadena-Castañeda, 2019, recently transferred by Gorochov (2020)from the Poculigera Group to incertae sedis. A different condition appears in the other species of the Poculigera Group,  Anaulacomera franciscoi Cadena-Castañeda, 2012and  Anaulacomera poculigeraHebard, 1924, where the second ramification is found at the apex of the cercus. However, some similarities between this new species and the species of the Poculigera Group are noteworthy, as the distinct coloration of the stridulatory area of the left tegmen when compared to the main coloration of the tegmina, a condition also found in  A. trispinata. So, considering the unusual shape of the main ramification of the cerci, besides the position of the second ramification on the structure, we decided to place  A. angelinae  sp. n.as incertae sedis. 3398547303 2020-02-03 BR, MNRJ Fianco, M.
