Pepoyara jagoi de Mello & Capellari, sp. n.

Etymology. Named after orthopterist friend Dr. Nicholas D. Jago, in memoriam.

Repositories. Holotype male, 3 female paratypes [MZSP]; 2 male, 4 female paratypes [Insect Collection, Botucatu Campus, Biosciences Institute, UNESP State University, São Paulo, Brazil];

Description. Male―Head: pale brown to yellowish, with some darker areas covered by short setae, except for two areas just above each antennal scape frons and gena ( Fig. 9 B, C); presence of a group of large, black bristles on each side of vertex and two rows of equally large bristles extending from ocellar triangle to the margin of frons. Clypeus and labrum dark yellow, antennal scape very large. Maxillary palpi as in Fig. 9 B. Thorax: disc of pronotum medium brown on a yellowish background, covered by many black, little to median-sized bristles and some larger scattered ones on the disc, lateral lobes dark brown. Fore wings as shown in Figure 9 A. Legs: femora yellowish, I and II with some light brown spots dorsally, III obliquely striped light brown and yellowish on external face; tibiae III yellowish to light brown; tarsi yellowish; hind basitarsus with an external apical spur just about as long as the last two joints. Abdomen: terga dark brown, with some dark yellow spots on tergites 6–9; sternites pale brown to yellow; supra-anal and subgenital plates brown; cerci as long as abdomen, yellowish. Phallic complex: as described for the genus, Fig. 08A, B and C.

Female— Very similar to males, except as follows: fore wings shorter, extending up to third abdominal tergite. Abdomen medium brown with yellow spots on tergites 2–9; posterior margins of tergites, specially on 6th–8th, with some large bristles. Ovipositor ca. 1.56 times longer than pronotum length, dark yellow at base and brown at apex; apical valves with teeth on dorsum.

Material examined. Holotype male, Brazil, SC, Pedras Grandes, Parque Ecológico Municipal. 13–14.i.1997, F. A. G. Mello leg; paratypes, same data, collectors and locality.

Remarks: Amanayara de Mello & Jacomini, 1994, and the two genera here described seems to comprise a natural cluster of Pteronemobiini restricted to southeast and south Brazil characterized by the following autapomorphies: 1—presence of a gland on the proximo-ventral face of lowermost dorsal spur on internal face of hind tibia (vestigial in Kevanemobius , gen. n.); 2—presence of teeth on dorsal margin of ovipositor distal valves.

One of us (de Mello) has observed that males of Amanayara piuna and Amanayara jutinga , while courting females, rub the glands mentioned above along their cerci, which suggests that those glands produce pheromones to attract nearby females and/or to provide them with orientation to come to copulatory position.
