Uma nova espécie de Tityus C. L. Koch, 1836 (Scorpiones, Buthidae) do estado da Bahia, Brasil

Abstract

A new species of the genus Tityus C. L. Koch, 1836 (Scorpiones, Buthidae) from the state of Bahia, Brasil. A new species of the genus Tityus C.L.Koch, 1836 (Scorpiones, Buthidae) is described from Anagé (36º44'14"S -08º08'41"W) and Poções (31º47'14"S -21º55'40"W), state of Bahia, Brazil. Tityus aba n. sp. belongs to the Tityus bahiensis group Lourenço, 2002 characterized by medium sized specimens, ranging from five to seven cm in length, reddish-brown or brownish coloration patterns and basal middle lamellae of female pectines not dilatated in most species. Within the group, this species is close to the Tityus stigmurus complex and is more related to Tityus stigmurus (Thorell, 1876), Tityus martinpaechi Lourenço, 2001 and Tityus melici Lourenço, 2003. T. aba n. sp. is distinguished from T. stigmurus by the color of the prossoma, which is almost black, by the higher number of pectinal teeth and by the larger body size. It is distinguished from T. martinpaechi mainly by the absence of dark spots on pedipalps and legs and also by the larger size of the specimens, and from T. melici , by the absence of dark confluent spots over the tergites and longitudinal strip between ventral keels of segments I to IV of the metasoma. Tityus aba n. sp. includes medium to large sized scorpions ranging from 6.0 to 7.65 cm, yellowish brown coloration pattern with an almost black carapace, with three longitudinal dark strips over the tergites, and with the dorsal medial keels of segment II to IV with a larger terminal granule that becomes spinoid on segments III and IV. The males are distinguished from the females by the slender pedipalps and more dilatated metasomal segments IV and V.Key words: Scorpiones, Buthidae, Tityus aba n.sp., Bahia, Brazil. ResumoUma nova espécie do gênero Tityus C.L. Koch, 1836 (Scorpiones, Buthidae) é descrita dos municípios de Anagé (36'44''14S -08'08''41W) e Poções (31'47''14S -21'55''40W) no estado da Bahia, Brasil. Tityus aba n. sp pertence ao grupo Tityus bahiensis (Lourenço, 2002), caracterizado por espécies de tamanho que variam de cinco a sete cm de comprimento, com colorido variando do amarelo -palha ao marrom avermelhado e sem a lâmina mediana basal dilatada nas fêmeas. Neste grupo, aproxima-se das espécies do complexo Tityus stigmurus (Lourenço, 2001). A nova espécie é mais próxima de Tityus stigmurus (Thorell, 1876), Tityus martinpaechi Lourenço, 2001 e de Tityus melici Lourenço, 2003, distinguindo-se da primeira por apresentar o prossoma quase totalmente negro, maior número de dentes pectíneos e tamanho maior; da segunda por não apresentar manchas nos palpos e pernas, ausência de uma mancha negra de forma triangular sobre o prossoma e também tamanho maior, a da última pela ausência de manchas confluentes no mesossoma e de faixa longitudinal na face ventral dos segmentos de I a IV do metassoma. Tityus aba n.sp. apresenta indivíduos de médio a grande porte, medindo de 6,0 a 7,65 centímetros, de colorido geral castanho claro, com prossoma escuro quase negro e tergitos com três faixas escu...

Scorpions, state of Bahia, northeastern Brazil

“…Koch, 1837) were identified ( Lourenço, 2004, A. mauryi Lourenço, 1982, Physoctonus debilis (C.L. Koch, 1840), Tityus aba Candido, Lucas, Souza, Diaz and Lira-da-Silva, 2005, T. brazilae Eickstedt, 1984, T. kuryi Lourenço, 1997, T. serrulatus andT. stigmurus].…”

“…However, since the 1980's this number is increasing, due to the expansion of field work and, consequently, publications, reaching a total of 18 species in last decade (Lira-da-Silva et al 2005). As a result of intensive field work in the last 12 years, three species were registered for the first time to Bahia (Lourenço 2002b, and another nine species belonging to four different genera were described (Lourenço 1997;Lourenço and Pinto-da-Rocha 1997;Lourenço 2001a;2003;2004;Lourenço et al 2004;Candido et al 2005;Lenarducci et al 2005;Giupponi et al 2009). Besides, one species was synonimized (Souza et al 2009) and another was relocated to a different genus (Lourenço 2007).…”

“…In order to complement the species lists and records, we also included data from taxonomic articles of the species whose type locality were in Bahia (Lourenço 1981;Lourenço and Eickstedt 1984;Lourenço 1997;Lourenço and Pinto-da-Rocha 1997;Lourenço 2001a;2003;2004;Lourenço et al 2004;Candido et al 2005;Lenarducci et al 2005;Giupponi et al 2009), and articles with the geographical distribution of scorpions which occur in this region (Maurano 1918;Pessôa 1935;Mello-Leitão 1945;Lourenço 1982a;b;c;Lourenço and Eickstedt 1988;Lourenço and Clodsley-Thompson 1996;Lira-da-Silva et al 1997;Lourenço and Clodsley-Thompson 1999;Fet et al 2000;Ministério da Saúde 2001;Lourenço 2001b;2002b;Kovařík 2003;Lira-da-Silva et al 2005;Santos et al 2006;Lourenço 2007;Bertani et al 2008;Souza et al 2009).…”

Scorpion diversity in two types of seasonally dry tropical forest in the semi-arid region of Northeastern Brazil

“…The diversity of scorpions recorded here is considered to be high given the fact that the survey was carried out in one of the driest areas of the caatinga biome, for a short period. It is possible that unknown species are described if more exhaustive field collections are accomplished, as evidenced by the recent description of Tityus alba in Northeastern Brazil (Candido et al 2005).…”
