TRIBE CEARACESAINI KOÇAK & KEMAL, 2010

Neomorphini Desutter, 1988: 364, Otte, 1994: 80, Cearacesaini Koçak & Kemal, 2010: 155, DesutterGrandcolas, 2017: 117–124, Cearacesaina Gorochov, 2017: 54.

Type genus: Cearacesa Koçak & Kemal, 2010 (for Neomorphus Desutter, 1988).

Distribution: Neotropics, only South America. Diagnosis: Small to medium-sized, FWs and HWs developed (except Taroba elephantina de Mello & Souza-Dias, 2010), surpassing abdomen, without stridulatory apparatus (Fig. 13A). Eyes crossed by horizontal bands, generally two or three (Figs 11A, 13A; Supporting Information, Fig. S1F); veins of lateral field of FWs parallel to dorsal field; TIII with 5/5 subapical spurs, sometimes six on inner side. Male genitalia: rami connected anteriorly (Fig. 13B; Supporting Information, Fig. S8I); ectophallic arc connected.

Included genera: Barota Gorochov, 2017, Cearacesa Koçak & Kemal, 2010, Najtaecesa Desutter-Grandcolas, 2017, Taroba de Mello & Souza-Dias, 2010 .

Remarks: Like Aphonomorphini crickets, Cearacesaini have developed FWs without stridulatory apparatus. However, this group does not have stridulatory teeth on the ventral face of the PCu vein, suggesting that these crickets do not use their tympana for acoustic communication. Their external morphology is extremely diverse between the species of this tribe (see: DesutterGrandcolas, 2017), so male genitalia are necessary for their identification. This is the only oecanthid taxon with the ectophallic arc complete (Fig. 13B).
