DE SOUSA, Leonardo; MANZANILLA, Jesús  and  PARRILLA-ALVAREZ, Pedro. Nueva especie de Tityus (Scorpiones: Buthidae) del Turimiquire, Venezuela. Rev. biol. trop [online]. 2006, vol.54, n.2, pp.489-504. ISSN 0034-7744.

A new species of Tityus (Scorpiones: Buthidae) from Turimiquire, Venezuela. We describe a new species of Buthid scorpion, Tityus quirogae, from the Turimiquire mountains, eastern side of the La Costa range, Monagas and Sucre States, Venezuela. It is morphologically similar to T. nematochirus and T. meridanus. It differs from these species in the distribution of the dorsal femoral trichobothria and in the following combination of characters: (1) I caudal segment with two parallel ventral keels. Caudal segments II to IV with ventral keels that are double in the extremes of the segments and single in the middle, (2) noticeable sexual dimorphism, especially in pedipalp shape; the male chelae are markedly thin and long, (3) number of pectineous teeth (male: 18 in each pecten; female: 18 in the right pecten and 19 in the left one), and (4) number of denticle rows in the movable finger of the right chela (16 in both sexes). T. quirogae is the first species of this genus, in the Northeastern region of Venezuela, with thin and elongated pedipalps. Rev. Biol. Trop. 54(2): 489-504. Epub 2006 Jun 01.
