description: TRIBE PAROECANTHINI GOROCHOV, 1986 DEFIN. NOV.
Paroecanthini Gorochov, 1986:516, Desutter, 1987: 235, Desutter, 1988: 369, Otte, 1994: 68, Gorochov, 2011: 217, Gorochov, 2017: 81, Campos, Souza-Dias & Nihei, 2020: 333, Campos & Desutter-Grandcolas, 2020: 356, Paroecanthina Gorochov, 2011:218, Gorochov, 2017: 81, Campos & Desutter-Grandcolas, 2020: 393.
Type genus: Paroecanthus Saussure, 1859.
Distribution: Neotropics. Diagnosis: Small to medium-sized, body somewhat flattened dorso-ventrally, FWs well developed bearing stridulatory apparatus (Fig. 17A). TI inner tympanum generally profound, sometimes covered by a sclerotized tab (Supporting Information, Fig. S5I); FWs stridulatory file bisinuous (Supporting Information, Fig. S3 Bc) with stridulatory teeth on proximal region; hv divided into two or more clusters (Fig. 17B); lateral field forming a> 90° angle with dorsal field (observed in posterior view, Supporting Information, Fig. S2J2). Male genitalia: generally reduced, mainly ectophallic invagination and endophallus (Fig. 17C; Supporting Information, Fig. S8B) (except Adenophallusia de Mello & de Camargo e Mello, 1996); MedLophi frequently absent; r two or more times longer than pseudepiphallic sclerite (Figs 17C, 20H, I; Supporting Information, Fig. S8B).
Included genera: Adenophallusia de Mello & de Camargo e Mello, 1996 (transferred from Tafaliscina), Angustitrella Gorochov, 2 0 1 1, Bofana Otte & Perez-Gelabert, 2009, Ectotrypa Saussure, 1874, Paroecanthus Saussure, 1859, Prodiatrypa Desutter, 1988 (transferred from Tafaliscina), SelƲagryllus Otte, 2006, Siccotrella Gorochov, 2011
Remarks: This tribe, recently transferred to Oecanthinae (Campos & Desutter-Grandcolas, 2020), was previously considered a tribe of Tafaliscinae (Desutter, 1988), corroborating in part with our results. The genus Prodiatrypa Desutter, 1988 has all the diagnostic characteristics of Paroecanthini, such as stridulatory veins bisinuous and regressed genital structures of males. Because of this, it is transferred to this tribe. Adenophallusia also has several Paroecanthini characters, like the bisinuous stridulatory file, the tip of the apex of the ovipositor rounded and the dorsal valves surface wrinkled. Besides, the phylogeny presented herein shows Adenophallusia belonging to the Paroecanthini clade. This relationship is not well supported. However, the morphological evidence indicates a close relationship between Adenophallusia and Paroecanthini crickets.
