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

No full textIntroduction Elliptical galaxies present a striking regularity in their global luminosity distributions. Within a wide range of sizes, the light profiles of elliptical galaxies can be described by the S'ersic law (e.g. Caon et al. 1993): \Sigma(R) = \Sigma 0 exp [\Gamma(R=a) ]. This regularity may be understood in terms of some relaxation process: elliptical galaxies seem to be in a quasi-equilibrium state. From the second law of thermodynamics, a system in equilibrium is in a maximum entropy state. Due to its long range, unshielded interactions, the thermodynamics of gravitational systems present some difficulties: maximizing the entropy, while keeping constant the mass and energy, results in an isothermal sphere (Lynden-Bell 1967). Here, instead of trying to obtain the expected final configuration by maximizing the entropy, we will admit the existe
Taiophlebia ferreirai Martins-Neto & Gallego & Brauckmann & Cruz 2007, comb. n.
No full textTaiophlebia ferreirai (Pinto, 1994), comb. n. Archaemegaptilus ferreirai Pinto, 1994: 107–108, fig. 1 (holotype BA-PB-638, studied). Remarks: A. ferreirai from the Upper Carboniferous (Piedra Shotle Formation, Chubut) of Argentina, was originally attributed to the palaeodictyopterans but clearly exhibits characters typical for Taiophlebia, and can be therefore transferred to the latter genus.Published as part of Martins-Neto, R.

Fig. 10 Etymology: Anagram derived from Nilson, Lorelai, Rita, Claus, Sonis, and Daiana, dynamic students of Geosciences Department, Universidade do Vale do Rio dos Sinos– UNISINOS, leadered by Dr Tania Lindner Dutra, the team that collected the holotype. Description: Fore wing 104 mm long and 34 mm wide, as preserved, with straight costal margin and slightly acuminate apex. Subcostal area notably wide close the base, progressively narrowing toward the apex. ScA well-defined with numerous secondary veinlets and anastomosed pattern of cross-veins. ScP long with at least two strong secondary branches and several, relatively long, distally dichotomous veinlets, unbranched. RP origin at 1/5 of wing base. RP slightly sigmoid, with five secondary branches. MA long, slightly sigmoid, three-branched. MP+CuA origin little before RP origin level with at least eight terminal branches, clade-like. CuP two-branched with CuP1 being the smallest, converging to MP+CuA, fusing distally; CuP partially preserved, oblique to anal margin, reaching it at about 1/3 of wing base. AP1 fuses to AP2 close to the wing base, Y-shaped.AP1+2 parallel to CuP2. Intense pattern of crossveins forming mosaics of heterogeneous cells in the whole preserved wing. No ornamentation pattern.
