Simothraulopsis rainori sp. nov. Boldrini, Lima & Salles (Figs. 2C, D, 3D–F and 4C, D) Diagnosis. Male imago:1)general coloration grayish brown(Figs.2C, D); 2) hind wing with costal projection forming a right angle, located approximately 1/2 distance from base to apex of wing (Figs. 3E, F); 3) telopenis spine-like, mid sized (less than the half of total length of penis lobes), and ventrally directed with apex bent outward (Figs. 4C, D); 5) penis lobes fused in their basal 1/3, with a well-marked sclerotized region; each lobe laterally swollen and protruding on the inner margin (Fig. 4D). Description Male imago LENGTH: body: 3.9–4.7 mm; forewing: 4.7–4.9 mm; hind wing: 0.6 mm. HEAD. Dorsal region dark brown, with black marks; ventral region light brown. Upper portion of compound eyes reddish brown, lower portion black (Fig. 2C). Scape and pedicel yellowish translucent, flagellum whitish translucent. THORAX. Pronotum dark brown; with medial and lateral black stripes. Mesonotum dark brown; longitudinal medial, anterolateral scutal, lateroparapsidal and medioparapsidal sutures light brown; posterior scutal protuberance, scuto-scutellar impression and scutellum dark brown. Pleura brown, washed with dark brown; membranous area yellowish. Metanotum dark brown (Figs. 2C, D). Sterna light brown, sutures darker. Wings membrane hyaline. Forewing with longitudinal veins light brown and cross veins translucent; costal brace and base of veins C, Sc and anal section dark brown; fork of vein MP slightly asymmetric (Fig. 3D). Hind wing with costal projection developed, forming right angle, located approximately 1/2 distance from base to apex of wing (Figs. 3E, F); longitudinal and cross veins yellowish brown, except basal part of costal and subcostal vein; distal lower portion of hind wing black (Fig. 3E). Coxae and trochanters brown. Leg. I: femur light brown with blackish line on ventral margin; tibia whitish, with blackish basal band; tarsi whitish. Legs II and III similar to leg I, except tibia brownish and tarsi yellowish. ABDOMEN.Terga grayish brown (Fig. 2D). Terga I, VIII–IX completely grayish brown; terga II–VII with anterior and anterolateral margins whitish; tergum X brown (Figs. 2C, D). Sterna whitish translucent; sterna IV–VII with lateral area brownish; sterna VIII–X brown. Genitalia (Figs. 4C, D). Styliger plate brown. Forceps segment I darkish brown, segments II and III lighter. Segment II 0.15x length of segment I and 1.0x length of segment III. Penis lobes yellowish, fused in their basal 1/3; each lobe rounded apically, separated by distance smaller than width of one penis lobe, with ventral spine-like telopenis, mid-sized (approximately half of the total length of penis lobes), ventrally directed with apex bent outward; ventral region of penis lobes with well-marked sclerotized region; each lobe laterally swollen and protruding on inner margin (Fig. 4D). Female and immature stages. Unknown. Etymology. The new species is named in honor of Rainor Abensour de Souza (Instituto Chico Mendes de Conservação da Biodiversidade) who helped during the collection of the type specimens. Material examined. Holotype: BRAZIL ♂; ROraima,AltO AlEgrE, FlOrEsta NaciOnal DE ROraima, RiO Mucajaí; 02°56´18.05″N / 61°37´27.28″ W; 20.XII.2017 – 05.I.2018, MalaisE trap., BOlDrini, R. cOl. Paratype: ♂, SamE Data as holotype. Discussion. Simothraulopsis rainori sp. nov. has morphological similarities with S. demerara and S. sabalo, sharing characteristics such as the shape of the penis lobes and having a mid-sized, spine-like telopenis on penis lobes. Imagos of S. rainori sp. nov., however, can be distinguished from them by the abdominal terga color (terga II–VII with anterior and anterolateral margins whitish in S. pacaraima, and terga II–V with anterior and anterolateral margins whitish S. inequalis), and by the spine-like telopenis being ventrally directed with apex bent outward (anteriorly projected in other two species), ventral region of penis lobes with a well-marked sclerotized region and laterally swollen and protruding on the inner margin. |
