Type material. Female holotype. Brazil, State of Espírito Santo, Santa Tereza, Reserva Augusto Ruschi ( T. Bernabe leg.), 2006. Paratypes. 1 male (juvenile), same data as for the holotype. Both deposited in the arachnological collection of the Museu Nacional , Rio de Janeiro, Brazil ( MNRJ – 11305). 1 female, Espírito Santo, Reserva Biológica ( REBIO) – Sooretama , Porteira Quirinão ( Exp. Arachné col.), 20/IV/2006, deposited in the Muséum national d’Histoire naturelle, Paris .

Diagnosis. Species of moderate to large size when compared with the average size of the other species of the genus (27.6 mm in total length; see Table I ). General coloration yellow to reddish-yellow with variegated dark pigmentation. Pedipalps slender; fingers with 6-7 rows of granules; male and female pectines with 13-14 teeth. The new species can be distinguished from other known species of the genus, also distributed in the Atlantic Forest region of Brazil, by: (i) a paler, reddish-yellow coloration and a distinct pattern of pigmentation on the chelicerae; these are not pigmented in the central zone, (ii) pedipalp fingers with have 6-7 rows of granules, (iii) male and female pectines with 13-14 teeth, (iv) anterior margin of the carapace with a sharp and convex projection; this character is better marked in adults. Th e new species is possibly an endemic element to the Atlantic Forest region.

Etymology. Patronym is in honor of biologist Tiago Nascimento Bernabé.

Description. Based on female holotype (measurements in Table I ).

Coloration. Generally yellow to reddish-yellow with dark brown to blackish pigmented zones on the body and its appendages. Prosoma: carapace reddish-yellow with blackish-brown spots on the anterior, lateral and posterior edges; eyes surrounded by black pigment. Mesosoma: reddish-yellow with confluent blackish zones on the posterior and lateral edges of tergites. Metasoma: segments I to III yellowish; IV-V reddish-yellow; all segments intensely marked with blackish-brown spots. Vesicle reddishyellow without any spots; the base of the aculeus reddish-yellow and the tip reddish. Venter yellowish; sternites with very diffused brownish spots. Chelicerae yellowish with variegated blackish-brown spots over almost the entire surface, with the exception of the central zone; fingers with blackish spots; teeth reddish. Pedipalps: yellowish; femur and patella with densely marked blackish-brown spots; chela hand almost entirely blackish-brown; fingers yellowish with dark on the extremities. Legs yellowish, with several blackish-brown spots.

Morphology. Carapace with coarse intense granulation; anterior margin not emarginated, almost straight, but with a sharp convex projection. Anterior median superciliary and posterior median carinae weak or absent. All furrows moderate to weak. Median ocular tubercle distinctly anterior to the centre of the carapace; median eyes separated by approximately 0.7 of one ocular diameter. Th ree pairs of lateral eyes. Sternum subpentagonal. Mesosoma: tergites with coarse intense granulation. Median carina moderate in all tergites. Tergite VII pentacarinate. Venter: genital operculum di-

vided longitudinally, each plate more or less sub-triangular in shape. Pectines: pectinal tooth count 14- 14 in holotype; 13-13 and 14- 14 in paratypes; basal middle lamellae of the pectines not dilated; fulcra absent. Sternites V to VII slightly granular; stigmata moderately elongate; setation moderate; sternite VII more intensely granulated and with four weakly marked carinae. Metasoma: segments I and II with 10 carinae, moderately crenulate. Segments III and IV with 8 carinae, moderately crenulate. Intercarinal spaces slightly granular, almost smooth. Segment V slightly rounded with 5 carinae. Telson moderately elongated, without granulations, smooth; with one ventral carina weakly marked; aculeus short and weakly curved; subaculear tooth strong and spinoid. Cheliceral dentition characteristic of the family Buthidae ( Vachon 1963) ; fixed finger with two moderate basal teeth; movable finger with two weak basal teeth; ventral aspect of both finger and manus with dense, long setae. Pedipalps: femur pentacarinate; patella and chela with weak to vestigial carinae; internal face of patella with 4-5 minute spinoid granules; all faces slightly granular, almost smooth. Fixed and movable fingers with 6-7 almost linear rows of granules; two small external and one internal accessory granule present at the base of each row; three granules in the extremity of the fingers; Trichobothriotaxy; orthobothriotaxy A-ss-beta ( Vachon 1974, 1975). Legs: tarsus with very numerous fine median setae ventrally. Tibial spurs moderately to strongly developed on legs III and IV.
