Kevanemobius Bolfarini & de Mello, gen. n.

(Figs. 0 1 to 05)

Type-specie: K. paulistorum , sp. n.

Etymology. Named after the Canadian orthopterist Dr. D. K. McE. Kevan, in memoriam.

Diagnosis. Male—Eyes large (not as prominent as in Amanayara ), with a despigmented band in the superointernal margin; fore wings short, reaching at most the middle of abdominal tergite III, dorsal field with parallel veins, without stridulatory file or any specialized areas for sound communication; fore tibiae without tympana; hind tibiae with 4 internal / 4 external dorsal spurs, 3 apical spurs on each side, being the superior the largest on the inner surface and the median the largest on the outer surface; phallic complex: pseudepiphallus large, the principal lobe with a pair of in-curved, latero-posterior projections, the posterior margin the projections sinuose, pseudepiphallic apodemes undeveloped, ectophallic fold not reaching the posterior margin of pseudepiphallus. Ovipositor valves with many teeth dorsally.

Description. Male—Head: oval in frontal view, with few bristles in fastigial area; inter-antennal space broad, almost twice the width of scape; large eyes but not much prominent, with a despigmented band at the inner superior edge; three ocelli present; 5th article of maxillary palpi elongated. Thorax: pronotum with many bristles, the disc with anterior and posterior margins straight, lateral lobes with the lower margin slightly concave at the middle. Mesothoracic wings abbreviated, not exceeding half of abdominal tergite III, without specialized areas for sound production and without stridulatory apparatus (pars stridens); dorsal field with five or six parallel veins united to each other by small transverse veins, lateral field with five veins below the angle, not connected by transverse veins. Metathoracic wings vestigial. Legs: fore tibiae without auditory tympana, 2 apical spurs present ventrally, the external longer than internal; middle tibiae with 3 apical spurs, 1 antero-dorsal and 2 ventral; hind tibiae: with four internal dorsal spurs, being the superior one glandular (as in all Pteronemobiini ) and the inferior one bearing vestiges of a ventral gland (more developed in Amanayara and Pepoyara , n. gen.), and four external spurs; three apical spurs present on each side, the superior the longest on the inner face, the median the longest on the outer face. Phallic complex (Fig. 03A, B, C). Pseudepiphallus elongated, apical portion with a pair of lateral, in-curved projections connected to each other by a sinuose horizontal margin (Fig. 03A); pseudepiphallic apodeme undeveloped; ectophallic apodemes road shaped, parallel; ectophallic fold not reaching the posterior margin of pseudepiphallic lobe; endophallic sclerite with 3 pigmented portions, lateral ones elongated, the proximal one garnished with a dorsal apodeme.

Female— Very similar to male, even in what concerns fore wing condition, but slightly larger. Ovipositor flattened laterally; apical valves with dorsal spines (Fig. 05).
