Cryptocearagryllus Martins-Neto & Tassi, 2009, n. gen.
No full textCryptocearagryllus n. gen. Etymology. Crypto, from Latin, hidden, and Cearagryllus, the closest genus Type species. Cearagryllus revelatus Martins-Neto, 1999, designated here. Diagnosis. Male tegmen with square rounded speculum. Two specular veins parallel to anal margin. Double diagonal vein. Both lanceolated cell and cua-m absent. CuP secondary branches aligned with the specular cross-veins and several CuA secondary branches. Discussion. Similar to Cearagryllus and Notocearagryllus in having two specular veins parallel to the anal margin and double diagonal vein, differing however in the square-rounded speculum shape. Similar to Allocearagryllus n. gen. in having a rather square speculum, differing however in the speculum having a more central position, with both anterior and posterior margins parallel to the anal margin. d 1 is similarly deflected to the speculum, although is notably longer. Cryptocearagryllus n. gen. has a wider costal area than Allocearagryllus n. gen., and a complex pattern of chords, especially between the diagonal veins and the posterolateral margin of the speculum, where the long cross-veins (apparently secondary branches of CuP) are aligned with the specular veins. Lanceolated cell absent. cua-m absent, although CuA slightly sinuous as in Notocearagryllus. The wide area filled with parallel cross-veins below the speculum is absent. CuA with several secondary branches, converging towards the costal area. Cryptocearagryllus n. gen. shares morphological characteristics with Notocearagryllus (the area below the speculum totally filled by perpendicular cross-veins) as well as Allocearagryllus (d 1 deflected to the speculum), and Cearagryllus (CuP and 1 A at the chords slightly curved). Cryptocearagryllus n. gen. differs from Cearagryllus as well as Notocearagryllus in lacking a d 2 deflection to CuA and in the speculum shape (rather trapezoidal in Cearagryllus and Notocearagryllus, square-rounded in Cryptocearagryllus n. gen. and Allocearagryllus), and by the absence of a wide area filled with long cross-veins below the speculum. Cryptocearagryllus n. gen. differs from Allocearagryllus in having a notably long d 1 (short in Allocearagryllus) and d 2 just slightly curved (strongly curved in Allocearagryllus). The CuP secondary branches aligned with the specular crossveins (apomorphic) and several CuA secondary branches (plesiomorphic) are morphological characters unique to Cryptocearagryllus.Published as part of Martins-Neto, Rafael Gioia & Tassi, Lara Vaz, 2009, The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa, pp. 21-37 in Zootaxa 2080 on page 26, DOI: 10.5281/zenodo.18734

Tatajuba Farm, near Santana do Cariri municipality, Ceará State, Northeast Brazil. Upper part of the Crato Member, laminated limestone level, lowest unit of the Santana Formation, Early Cretaceous (Upper Aptian), Araripe Basin. Remarks. The placement of this species in the subfamily Baissogryllinae Gorochov is based on plesiomorphic characters: lanceolated cell present; CuA unbranched; speculum trapezoidal with indistinct number of specular veins (more than three); diagonal vein not deflected.Published as part of Martins-Neto, Rafael Gioia & Tassi, Lara Vaz, 2009, The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa, pp. 21-37 in Zootaxa 2080 on page 22, DOI: 10.5281/zenodo.18734
Cearagryllus Martins-Neto 1991
No full textCearagryllus Martins-Neto, 1991 Type species. Cearagryllus monstruosus Martins-Neto, 1991, by original designation. Remarks. The type species of the genus was based on a poorly preserved specimen, with an incomplete tegmen. A re-examination of the original material (Figure 2 B) reveals the existence of all diagnostic characters proposed for the subfamily. Species included (males): Cearagryllus monstruosus Martins-Neto, 1991 (the type species, Fig. 1 D); Cearagryllus gorochovi Martins-Neto, 1991 and Cearagryllus robustus Martins-Neto, 1991.Published as part of Martins-Neto, Rafael Gioia & Tassi, Lara Vaz, 2009, The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa, pp. 21-37 in Zootaxa 2080 on page 23, DOI: 10.5281/zenodo.18734
Santanagryllus Martins-Neto 1991
No full textSantanagryllus Martins-Neto, 1991 Type species. Santanagryllus hesselae Martins-Neto, 1991 by original designation. Remarks. Santanagryllus Martins-Neto differs from Cearagryllus, the closest genus, in having a straight anterior margin of the speculum, twice as long as the posterior margin. Additionally, in Santanagryllus R and CuA are sinuous and distally convergent. Santanagryllus shares with Notocearagryllus a wider area below the speculum, differing however in the shape of the speculum (rather trapezoidal in Santanagryllus, squarerounded in Cearagryllus and Notocearagryllus).Published as part of Martins-Neto, Rafael Gioia & Tassi, Lara Vaz, 2009, The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa, pp. 21-37 in Zootaxa 2080 on page 23, DOI: 10.5281/zenodo.18734

Cearagrylloides microcephalus Martins-Neto, n. comb.
No full textCearagrylloides microcephalus Martins-Neto, n. comb. (Figs. 2 B, E, G) 1. Cearagryllus microcephalus Martins-Neto, 1991. Specimens included. GP/ 1 T- 1680 (holotype), RGMN- 203, CV- 1699, and RGMN- 40 (510) New supplementary material. RGMN- 508. Emended diagnosis. Females with robust body, varying from 24 to 26 mm length; fore wing length varying from 24 to 28 mm; ovipositor length around 38 mm. Ovipositor 1.6 times longer than the body and/or the fore wing length. Head notably small, laterally elongated. ScP straight, not thickened; R parallel to ScP. MP unbranched; around six MP 2 secondary branches. r-m indistinct. Discussion. The specimen CV- 1699, with incompletely preserved ovipositor, was initially interpreted as belonging to the species Cearagryllus perforatorius (Martins-Neto, 1991), based just on the body and wing length. However, after re-examination of the venation of this specimen, it is now possible to verify that it belongs to Cearagrylloides microcephalus. In addition to the original characters assigned to the species (smaller body and head, longer ovipositor), the fore wing provided other important characters. In C. perforatorius ScP is sigmoid, distally divergent and basally thickened, in contrast to C. microcephalus, which exhibits a straight ScP, not thickened. Additionally, MA has typically three anterior secondary branches, not present in C. microcephalus. Another minor difference is a smaller number of MP secondary branches.Published as part of Martins-Neto, Rafael Gioia & Tassi, Lara Vaz, 2009, The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa, pp. 21-37 in Zootaxa 2080 on page 28, DOI: 10.5281/zenodo.18734
