Thorax. Pronotum translucent, laterally yellowish and grayish black medially. Mesonotum yellowish brown, margins and carinae yellowish, mesoscutellum slightly darker. Thoracic pleurae yellowish white, sterna brownish laterally, grayish medially.
Wings. Membrane of wings hyaline, except basal half of C and Sc areas shaded with gray; longitudinal veins brownish, crossveins yellowish translucent. Forewing veins IMP and MP2 joined by crossveins (Fig. 1). Marginal intercalaries absent. Hind wing present, with 3 longitudinal veins (Fig. 2).
Legs. Yellowish translucent, except foreleg shaded with gray on femur; all femora with subapical dark marks.
Abdomen. Translucent shaded diffusely with gray, segment IX–X whitish; lateral margins darker.
Genitalia. Styliger plate yellowish white; posterolateral projections of styliger plate and forceps segment I yellowish, rest of forceps and penes whitish. Penes wider distally, with ventral spines inserted laterally (Fig. 4). Posterolateral projections of styliger plate relatively very short and pointed distally (Fig. 3). Dorsal accessory structure single (Fig. 3). Caudal filaments whitish translucent.
Nymph. Unknown.
Etymology. The name is an allusion to a famous musical style of Pernambuco State.
Diagnosis. Traverhyphes (Traverhyphes) frevo sp. nov. can be distinguished from the other species of the genus by the following combination of characteristics: 1) abdomen translucent shaded with grayish, segment I–X whitish; 2) penes wider distally (Fig. 4); 3) penile spines curved, inserted laterally; 4) posterolateral projections of styliger very short and pointed distally, in lateral view (Fig. 3); 5) vein IMP and MP2 of forewings joined by crossveins (Fig. 1).
Material. Holotype. Brazil, Pernambuco State, Bonito (S08°31'58.59", W035°43'26.32") male imago, 29.i.2010, Lima, LRC col. (PPGBT). Paratypes. Same data as holotype, 4 male imago (light trap), Lima LRC, Nicacio G colls. (PPGBT); same data except 1 male imago (UFPE).
Comments. This species is similar to Traverhyphes (Traverhyphes) pirai Molineri, 2001 due the insertion of penile spines and by the penes wider distally. However, it can be distinguished from this species by the size of the posterolateral projections of styliger plate, which is very short in the new species, and because it are pointed distally.
