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 Notocearagryllus Martins-Neto, 1999 Type species. Notocearagryllus dutrae Martins-Neto, 1999 , by original designation. Remarks. Notocearagryllus is closely related to Cearagryllus , exhibiting many of the diagnostic characters of it. The main differences are the presence of a conspicuous lanceolated cell, constricted at its base (plesiomorphic, shared with several other gryllid groups, for example Araripegryllus Martins-Neto, 1987 ), and the space between the diagonal vein and the base of CuP at the chords being filled with perpendicular cross-veins (filled just up to the anterior and the anterolateral speculum boundary in Cearagryllus ). However, the lanceolated cell, if it exists, has not been observed in any of the Cearagryllus species. Additionally, Notocearagryllus exhibits several perpendicular cross-veins in the anal area (not evident in any of the Cearagryllus species) and the chords are more conspicuously curved (slightly curved in all species of Cearagryllus and Santanagryllus ). Notocearagryllus also exhibits a sigmoid CuA , apically converging towards the posterior tegmen margin, more curved chords (extension of CuP , 1A and 2A after the “Z” at the tegmen base) and a wider apical area. Another apomorphic character is the partial fusion of 1A and 2A at the distal part of the “Z”.
