Comments. The male was recently described by Souza et al (2006, fig. 9A–B), and some details on female variability were given. Here the distribution range of the species is extended to the States of Bahia and Paraíba, previously only known from Ceará.

Diagnosis. Male. This species differs from the others of the complex by presence of three dark brown longitudinal stripes on tegites, except by T. aba and T. stigmurus . Tityus martinpaechi can be distinguished from T. stigmurus by a different pattern of pigmentation with 3 longitudinal dark brown stripes on tergites which begin at the posterior edge of the carapace, the lateral ones reaching the VI tergite and the central reaching the VII, carapace with some dark brown spots ( Fig. 9 A–B), only one pair of posterior spinoid granule on dorsal carinae of metasomal segment IV, whereas T. stigmurus has a single longitudinal dark brown stripe on tergites which reaching the VII tergite and carapace with only one triangular dark brown spot on anterior region ( Fig. 16 A–B), two pairs of posterior spinoid granule on the dorsal lateral carinae of segment IV that are more conspicuous ( Fig. 17 C–D); the total length are greatest for T. martinpaechi (male 73,6; female 64,7 mm) when compared with T. stigmurus (male 60,3–63,8; female 55,6–57,1 mm). Tityus martinpaechi can be distinguished from T. aba by a smallest number of pectinal teeth (male 22–21), different pattern of pigmentation with sparse dark brown spots on carapace, palps, legs and morphology of the palps (length T. martinpaechi femur: 7.2; tibia: 7.4; chela: 13.3) and metasomal segments (length T. martinpaechi : I=6.3; II=7.7; III=7.8; IV=8.8; V=8.6) which are stouter ( Fig. 9 A–B), whereas T. aba has carapace almost all blackish, absence of sparse dark brown spots on palps and legs ( Fig. 1 A–B), largest number of pectinal teeth (23–26, 26–25 e 26–27) and palps (length T. aba femur: 8.3; tibia: 8.7; chela: 14.9; fig. 9A–B) and metasomal segments (length T. aba : I=6.3; II=7.7; III=8.3; IV=9.3; V=9.3) which are slender ( Fig. 2 B).

Female. See Souza et al (2006).

Distribution. States of Ceará, Paraíba, and Bahia, Brazil ( Fig. 10 ).
