03F15D3E8C04FFFB3ED3F8D9AF49FD1A.taxon	discussion	Discussion. The most typical representative of the subfamily, the type genus Cearagryllus, was interpreted by Gorochov (1995) as belonging to the Baissogryllinae Gorochov based on plesiomorphic characters (several specular veins and general shape of the speculum). Cearagryllus exhibits an unique set of apomorphic characters that distinguish it from all other Cretaceous baissogryllid-like ensiferans, such as the double diagonal veins, the d 2 deflection and the presence of the veinlet d-am, which justify its inclusion in a distinct subfamily, as proposed here. The two genera proposed for female species are included in the subfamily on the basis of the great similarity of body shape to that of the males. The ovipositor length, apomorphic for this group, and the notably short cerci are characteristics that distinguish this female group from all other known female grylloids.	en	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.

Notocearagryllus dutrae Martins-Neto, 1999, by original designation.	en	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.

03F15D3E8C07FFFA3ED3F8DAAC84FDBC.taxon	discussion	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, 1 A and 2 A after the “ Z ” at the tegmen base) and a wider apical area. Another apomorphic character is the partial fusion of 1 A and 2 A at the distal part of the “ Z ”.	en	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.

03F15D3E8C01FFFD3ED3FF69A93EFC3E.taxon	discussion	Discussion. Similar to Notocearagryllus Martins-Neto, 1999 in the general aspect of the tegmen morphology, differing however in features of the speculum: the posterior margin is slightly shorter than the anterior in Allocearagryllus n. gen. (posterior longer than anterior in Notocearagryllus); sp 1 converges on sp 2 in Allocearagryllus n. gen. (parallel in Notocearagryllus); sp 2 origin is at the base of the posterolateral margin of the speculum in Allocearagryllus n. gen. (at the posterior margin in Notocearagryllus). Additionally, the CuA secondary branches begin above the speculum in Allocearagryllus n. gen., and after the speculum in Notocearagryllus. Allocearagryllus n. gen. is also larger: tegmen length 25 mm as preserved (representing about 2 / 3 total length), compared with a total tegmen length of around 22 mm in Notocearagryllus. The features outlined above also distinguish the new genus from Cearagryllus. The d vein deflects at the anterior margin of the speculum in both Notocearagryllus and Cearagryllus, and d is curved forward in Allocearagryllus n. gen. The area below the posterior margin of the speculum is as wide as the adjacent ones in Allocearagryllus n. gen., wider in both Cearagryllus and Notocearagryllus.	en	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.

03F15D3E8C00FFFF3ED3FAEFACECFE72.taxon	discussion	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.	en	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.

03F15D3E8C03FFFE3ED3FA02AC6AFCAE.taxon	discussion	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.	en	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.

03F15D3E8C02FFFE3ED3FC88A844F98C.taxon	discussion	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.	en	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.

03F15D3E8C02FFF13ED3F969AC9BF924.taxon	discussion	Remarks. The wing venation remains unknown for this species, which differs from the others in the genus (females) in having a smaller body and ovipositor. The body is oval, about as long as wide. Some other differences, such as a wing length greater than the body length and about as long as the ovipositor, and the ovipositor length / body length ratio of around 1.20 are characteristics that sustain C. previstus as a different species. It is interesting to note that in plotting body length x ovipositor length (Fig. 4) for the C. perforatorius specimens, the trend line is straight. Including C. previstus, the trend line curve remains straight (but would not for C. microcephalus). C. previstus could be the direct ancestor of C. perforatorius (or vice versa?) or sibling species both derived from an unknown common ancestor?. This presents an ecological problem (see further discussion below), a similar situation to that seen with two species of the Caelifera Cratoelcana (see Martins-Neto, 1995).	en	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.

03F15D3E8C0DFFF03ED3F90EA995FE54.taxon	discussion	Discussion. Paracearagryllus Martins-Neto, n. gen. shares morphological characteristics of the three described species of Cearagrylloides n. gen.: from C. perforatorius the curved ScP and R; from C. microcephalus, the origin of MP close to the wing base and distally branched, and from C. previstus, the small body length. P. poliacanthus differs from C. perforatorius in the lack of a sigmoid ScP which is not thickened at its base (the P. poliacanthus curvature of ScP is probably a preservational distortion); differs from C. microcephalus in having MA two-branched, branching at the mid length of the wing (just a distal branch in C. microcephalus), and differs from C. previstus in having a notably smaller body size and the wings as long as the body. Paracearagryllus poliacanthus also differs from all three species in having a small ovipositor (around 60 % of the body length) and a greater number of cubital secondary branches.	en	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.
