Bioacoustics of Leptopsis (Aberracla)

DESCRIPTION General morphology Medium size crickets with elongate and thin shape; body shiny and not setose ( Fig. 16A ). Fastigium wider than scape at base, thinner at apex, not separated from vertex by a transverse furrow or a shallow depression ( Fig. 16B ). Eyes ( Fig. 16C, D ) small, not protruding. Ocelli not reduced, set as a triangle; distance between lateral ocelli equal to distance between median and one lateral ocelli; median ocellus vertical, almost apical on vertex. Maxillary palpi ( Fig. 16C ) very elongate and extremely thin; article 3 slightly shorter than article 4; article 5 a little longer than article 4, regularly widened toward apex, truncate obliquely at apex. Pronotum longer than wide, not at all transverse ( Fig. 16B ). Legs elongate and very thin. TI with a small inner and a small outer tympanum; two apical, ventral spurs, small compared to basitarsomere I. TII with two ventral, apical spurs. TIII with 4/4 subapical spurs, very short and alternate, in TIII distal half; with 3/3 apical spurs ( Fig. 16E, F ): inner spurs longer than outer spurs; median and dorsal inner spurs subequal and very long, dorsal apical spur as long as half basitarsomere III; ventral and dorsal outer spur subequal, median outer spur twice as long as ventral and dorsal outer spurs.TIII serrulation strong between and above subapical spurs. FIII with a long filiform apical part, about half its total length ( Fig. 16A ). Basitarsomeres all very long and thin ( Fig. 16A ). Basitarsomeres III with small inner and outer dorsal spines, in addition to apical ones. Cerci shorter than abdomen. Coloration Uniform, except for a yellow longitudinal band running from labrum through the face, occiput, pronotum DD and perhaps tergite I. Legs almost completely uniformly colored. Male FWs ( Fig. 16B, C ) very short, not reaching tergite I distal margin; not completely overlapping dorsally; without glandular structures; left FW apparently not membranous. Venation: no stridulatory structures; lateral field with four longitudinal parallel veins. HWs lacking. Tergites without glandular structures. Supra anal plate quadrangular; a pair of strong setae bunches on distal margin, the setae regularly arranged according to their size ( Fig. 16G ). Subgenital plate short, high, deeply furrowed on apical third. Male genitalia ( Fig. 17 ) Pseudepiphallic sclerite rounded and vertical, without extended rami; inner side of pseudepiphallic sclerite with a pair of projections that come against ectophallic apodemes; pseudepiphallic arms very short, A-sclerite well developed, having the shape of concave lamellas; pseudepiphallic parameres very small, located on inner margin of A-sclerites. Ectophallic fold very short; ectophallic apodemes short and wide, thinner toward apex. Endophallic sclerite short, with well developed endophallic apodemes (both a high longitudinal crest and a distal lamella). No phallic glands. Female Unknown.
