Gnomidolon pulchrum Martins 1960
No full textGnomidolon pulchrum Martins, 1960 (Fig. 2) Gnomidolon pulchrum Martins, 1960: 7; Monné, 2005: 313 (cat.). Martins (2006) called attention to the variation in color of G. pulchrum. The typical form, with the apical half of the elytra reddish, occurs in the south-central part of Paraguay (San Pedro, Cordillera) and in northern Argentina. The form with the apical half of the elytra black is recorded for Brazil (Mato Grosso), but also occurs in northern Paraguay (Concepción). The typical form has been illustrated in color by Martins (1967: 210, est. 7, fig. 2; 2006: 169, fig. 183). A female from Bolivia before us agrees with the form that shows the apical half of the elytra black, but the extremities of the elytra have a narrow transverse white stripe (Fig. 2). Structurally, the specimen agrees morphologically with the other forms cited. Specimens examined. BOLIVIA, Santa Cruz: Albanez (40 km S S(santa)C(cruz), “Laspetas”, fêmea, 6.XII. 2011, J. L.

Evolution of the G+C content frontier in the rat cytomegalovirus genome
No full textWithin the 230138 bp of the rat cytomegalovirus (RCMV) genome, the G+C content changes abruptly at position 142644, constituting a G+C content frontier. To the left of this point, overall G+C content is 69.2%, and to the right it is only 47.6%. A region of extremely low G+C content (33.8%) is found in the 5 kb immediately to the right of the frontier, in which there are no predicted coding sequences. To the right of position 147501, the G+C content rises and predicted coding sequences reappear. However, these genes are much shorter (average 848bp, 50% G+C) than those in the left two-thirds of the genome (average 1462bp, 70% G+C). Whole genome alignment of several viruses indicates that the initial ultra-low G+C region appeared in the common ancestor of the genera Cytomegalovirus and Muromegalovirus, and that the lowering of G+C in the right third has been a subsequent process in the lineage leading to RCMV. The left two-thirds of RCMV has stop codon occurrences at 67.5% of their expected level, based on a modified Markov chain model of stop codon distribution, and the corresponding figure for the right third is 78%. Therefore, despite heavy mutation pressure, selective constraint has operated in the right third of the RCMV genome to maintain a degree of gene length unusual for such low G+C sequences

Taiophlebia ferreirai Martins-Neto & Gallego & Brauckmann & Cruz 2007, comb. n.

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.

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
