Descrição de uma nova espécie de Rhopalurus thorell, 1876 (scorpiones: Buthidae) do nordeste brasileiro

Abstract

Rhopalurus guanambiensis n. sp. is described from Guanambi, state of Bahia, northeastern Brazil. The new species is related to R. lacrau Lourenço & Pinto-da-Rocha, 1997 (Itaeté, state of Bahia) by having the same number of oblique rows of granules on the movable finger of the pedipalpal chela, same number of keels on metasomal segments I, III, IV, V and similar body size; it is related to R. crassicauda Di Caporiacco, 1947 (state of Roraima) by having the same number of keels on metasomal segments I, II, IV and V, last two metasomal segments darker colored and enlarged, and similar body size. It is distinguished from R. lacrau by the different color of the carapace, meso and metasomal segments IV-V, higher number of pectinal teeth and metasomal segment II with ten carinae; and from R. crassicauda by the lower number of oblique rows of granules on the movable finger of the pedipalp chela, metasomal segment III with eight carinae; segment V with vestigial keels and by the telson with a strong subaculear tubercle. The males of R. guanambiensis are distinguished from the female by having more robust pedipalp chelae and by the enlarged metasomal segments IV and V. This species raises the total number of species of the genus Rhopalurus in Brazil to nine.Key words: Scorpiones, Buthidae, Rhopalurus guanambiensis n. sp., Northeastern Brazil. ResumoRhopalurus guanambiensis n.sp. é descrita de Guanambi, Estado da Bahia, nordeste do Brasil. A nova espécie aproxima-se de R. lacrau Lourenço & Pinto-da-Rocha, 1997 (Itaeté, Estado da Bahia) por apresentar o mesmo número de séries de grânulos no dedo móvel da quela do pedipalpo, igual quantidade de carenas nos segmentos metasomais I, III, IV e V e pelo tamanho do corpo semelhante; aproxima-se de R. crassicauda Di Caporiacco, 1947 (Estado da Roraima) por apresentar o mesmo número de carenas nos segmentos metasomais I, II, IV e V, pela coloração mais escura dos dois últimos segmentos metasomais, que são dilatados e por apresentar aproximadamente o mesmo tamanho. Distingue-se de R. lacrau pela coloração diferente da carapaça, mesosoma e dos segmentos metasomais IV-V, maior número de dentes pectínios e pela presença de dez carenas no segmento metasomal II; de R. crassicauda, devido ao menor número de séries de grânulos no dedo móvel da quela do pedipalpo, maior número de dentes pectíneos, presença de oito carenas no segmento metasomal III e por apresentar um tubérculo subaculear acentuado no telson e carenas do segmento V do metasoma vestigiais. O macho de R. guanambiensis distingue-se da fêmea pela mão mais robusta e pela dilatação dos dois últimos segmentos do metasoma. A descrição desta espécie amplia para nove o número de espécies que ocorrem no Brasil. Palavras

“…The hemispermatophore of Chaneke is structurally similar to those of various members of the New World genera Tityus, Centruroides, Rhopalurus and Zabius that have been recorded in the literature (e.g. Maury, 1970;Francke & Stockwell, 1987;Stockwell, 1989;Lenarducci et. al., 2005;Ojanguren-Affilastro, 2005;Prendini et.…”

On the enigmatic troglobitic scorpion Troglorhopalurus translucidus: distribution, description of adult females, life history and comments on Rhopalurus lacrau (Scorpiones: Buthidae)

“…The only known species of Rhopalurus that occur at the Chapada Diamantina region and its surroundings are R. lacrau, R. rochai and Rhopalurus guanambiensis Lenarducci, Pinto-da-Rocha & Lucas, 2005(lenarduCCi et al 2005, Porto et al 2010. Only R. lacrau shares some morphological characteristics with T. translucidus -metasomal carination (10-8-8-8-5), number of pectinal tooth (17), peg sensillae shape (Figs.…”

Rhopalurus rochai possesses 10-10-10-8-5 metasomal carinae and 21-27 pectinal teeth and R. guanambiensis possesses 27 pectinal teeth and 10-10-8-8-5 metasomal carinae besides both are epigean scorpions and have a stridulatory apparatus (lourenço & Cloudsley-tHomPson 1995, lenarduCCi et al 2005.
