ABSTRACT We report the first pediatric case of a Jaguajir agamemnon scorpion sting. This case occurred in the state of Paraná and is the first record of this species in southern Brazil. The patient was admitted within 15 min, with pain, local edema, erythema, whole-body pruritus, and tongue paresthesia within the first two hours, which disappeared thereafter. The patient’s condition was considered mild, with a positive outcome, and she recovered completely.

Uma 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 Tityusbahiensis (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 Tityusstigmurus (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 escuras longitudinais, sendo uma mediana e duas laterais; carenas medianas dorsais dos segmentos II a IV com o último granulo maior, tornando-se espiniforme nos segmentos III e IV. Os machos apresentam os palpos mais delgados em relação às fêmeas e os segmentos IV e V do metassoma mais dilatados.

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 Tityusbahiensis 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 Tityusstigmurus (Thorell, 1876), Tityusmartinpaechi 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.
