The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa Author Martins-Neto, Rafael Gioia Author Tassi, Lara Vaz text Zootaxa 2009 2080 21 37 journal article 10.5281/zenodo.187344 229e851e-7107-4628-b823-7bf467cc98ad 1175-5326 187344 Cearagrylloides perforatorius Martins-Neto , n. comb. (Pl. IIB; Figs. 2 A, D, H.) 1. Cearagryllus perforatorius Martins-Neto, 1991 . Specimens included. CV-6015 ( holotype ), DGM-6281 ( paratype ), CD-I-41, CV-1020, and the supplementary material originally included, RGMN-662, CV-6015, CV-2429, and RGMN-901. Additional specimens included. CV-1980, RGMN-506, and RGMN-507. Specimens excluded. CV-1699, RGMN-203, CD-I-123, and CV-257. Emended diagnosis. Females with robust body, varying from 29 to 32 mm length; fore wing length varying from 28 to 32 mm ; ovipositor length varying from 32 to 36 mm . Ovipositor 1.1 times longer than the body and/or the fore wing length. Relatively large and dorsally rounded head. Fore wing about three times longer than wide; ScP sigmoid, distally converging towards the costal margin and notably thickened basally; R parallel to ScP . MP two-branched; around nine MP2 secondary branches. r-m present, connecting R to MA . Discussion. Following the examination of new supplementary material (especially well-preserved wings), several apomorphies of this species can be recognized, such as the sigmoid ScP , thickened at its base, as well as the presence of r-m , confirmed in all observed specimens. Description (supplementary material RGMN-506). Body and forewing length 32 mm . Ovipositor length as preserved 32 mm (total length ca. 36 mm ). Fore tibia smooth with a relatively long apical spur. Fore wing ( Fig. 3 A) three times longer than wide, with wide costal area, narrowing towards the apex, filled by rather long cross-veins and accessory veinlets forming a mosaic of heterogeneous cells. ScP sigmoid, thickened at its base, converging towards the costal margin around a quarter wing-length from the apex. R parallel to ScP . M three-branched. Presence of r-m connecting R to MA , situated at the mid length of the wing. At least nine MP2 secondary branches, all connected by cross-veins, forming a mosaic of heterogeneous cells. Remarks. The specimen CV-1980, an isolated fore wing, was figured by Martins-Neto (1991) as belonging to Cearagryllus poliacanthus . Its wing venation is, in fact, virtually identical to that of Cearagrylloides perforatorius Martins-Neto (1991) , to which species it is now transferred. The specimen CV- 257 does not exhibit sufficient diagnostic characters to be included in the species, being now considered Cearagrylloides sp.
