description: Desutterella Souza-Dias, Campos & de Mello n. gen.
Etymology. Taxon named after the French Orthopterist Laure Desutter-Grandcolas, for her work on Neotropical Grylloidea.
Type species. Desutterella manauara Souza-Dias, Campos & de Mello n. sp.
Species included. Desutterella manauara Souza-Dias, Campos & de Mello n. sp., Desutterella colombiana Souza-Dias, n. sp.
Distribution. Amazon Forest, in Brazil (Amazonas State), and Colombia (Amazonas Department).
Diagnosis. Size small, slender, as the other genera from Aracambiae group. General coloration light to medium brown. Head, pronotum and legs I and II with sparse, thick setae. Fastigium with double row of thick setae. Three ocelli, large, circular. Maxillary palpi elongated, joints 3–5 whitish, pilose. Legs elongated, not annulated; tympanum on inner face of TI. Male. Metanotum with two projections rounded, whitish, glandular. Male FWs short, rounded, membranous; right FW medium brown, apex light brown, pilose; stridulatory file very reduced; veins and areas for sound propagation absent. Male genitalia. Male genitalia bearing a pair of genital glands within pseudepiphallic sclerite, connected to tubular pseudepiphallic arms. Pseudepiphallic arms curved outwards. Pseudepiphallic parameres highly sclerotized; PsP2 with two pairs of distinct projections. Female. Almost same size as males. Females FWs yellowish brown, transparent, small, reaching first abdominal tergite.
Description. Occiput and vertex with thick setae (Figs. 2 A–D, 5 A–C). Fastigium wider than long, with double row of thick setae, below vertex level and not separated from it by line or furrow (Figs. 2 A–D, G, 5 A–C, F). Three ocelli, large, circular (Figs. 2G, 5F). Antennal scape longer than wide (Figs. 2 A–D, 5 A–C). Maxillary palpi elongated, joints 3–5 elongated, whitish, pilose, joint 4 longest (Figs. 2J, 5E); joint 5 curved, apex rounded (Figs. 2J, 5E). Pronotum DD longer than wide, with thick setae, mainly on cephalic margin (Figs. 2 A–F, 5A, B). Tergites slightly pubescent, without apparent tergal glands (Figs. 2A, B, D, 5A). Legs I and II not annulated, with thick setae. Tympanum on inner face of TI. TIII not annulated. Subapical spurs 4/4, with serrulation between and above them; inner distal subapical spur near upper apical; apical spurs 3/3, more developed on inner face; inner apical spurs: dorsal longest (iad), median slightly shorter (iam), ventral smaller (iav) (iad>iam>iav); outer apical spurs: median longest (oam), dorsal slightly shorter (oad), ventral smaller (oav) (oam>oad>oav). Basitarsus III with double row of spines.
Male. Metanotum with two glandular projections whitish, rounded (Figs. 2D, E, 3 A–B, 5D). Male FWs short, reaching half of abdomen (Figs. 1A, 2A, 5A); right FW medium brown, pilose (Figs. 2A, C, 5 A–C); without specialized veins or areas for sound production and propagation; left FW membranous, transparent, lateral field medium brown (Fig. 5D). Supra anal plate not constricted medially (Figs. 2H, 5H); distal margin without extended angles (Figs. 2H, 5H). Subgenital plate elongated, pubescent (Figs. 2I, 5G).
Male genitalia. Male genitalia bearing a pair of genital glands within pseudepiphallic sclerite, connected to tubular pseudepiphallic arms (Figs. 4 A–C, 6 A–C). Pseudepiphallus: pseudepiphallic sclerite transverse, (Figs. 4 A–C, 6 A–C); pseudepiphallic arms curved outwards (Figs. 4A, B, 6A, B); apex with opening duct, rounded. Rami elongated, connected to pseudepiphallic sclerite, reaching apex of ectophallic apodemes (Figs. 4A, 6A). Pseudepiphallic parameres (PsP) highly sclerotized (Figs. 4 A–C, 6 A–C); PsP2 with two pairs of distinct projections: one elongated, upcurved, lateral; second small, medial, semicircular, visible in dorsal view (Figs. 4A, 6A); PsP1 elongated (Figs. 4B, 6B). Ectophallic invagination. Ectophallic apodemes elongated, thin (Figs. 4A, 6A). Ectophallic fold sclerotized, surrounding apex of medio-posterior projection of endophallic sclerite (Figs. 4B, 6B). Endophallus. Endophallic sclerite large, flat (Figs. 4B, 6B); latero-posterior projections short; medio-posterior projection elongated (Figs. 4B, 6B). Endophallic apodeme paired, curved outwards, apex pointed (Figs. 4B, 6B).
Female. In comparison with other Luzarinae crickets, females of Desutterella Souza-Dias, Campos & de Mello n. gen. are almost same-sized as males—in the Aracambiae genera, frequently the females are larger than males. Head, pronotum, abdomen and legs with thick setae (Figs. 1B, 2B). Females FWs small, translucent, reaching half of first tergite (Figs. 2B, F). Supra anal plate pubescent, slightly constricted medially (Figs. 2K). Subgenital plate pubescent, small (Figs. 2L). Female genitalia: copulatory papilla small, basis rounded, apex pointed centrally (Figs. 3 D–F).
