Species of moderate to large size when compared with the average size of the other species within the genus, ranging from 44 to 50 mm in total length. General coloration reddish to dark reddish. Carapace reddish with some light brown zones on the anterior edge and around the ocular tubercle; the areas between the anterior edge and the ocular tubercle as well as areas of furrows almost without pigmentation; ocular tubercle dark, almost black. Tergites reddish with several yellowish reticular diffuse spots on all tergites. Sternites yellowish with brown spots on lateral edges, especially on sternites VI and VII; pectines and genital operculum yellow ochre. Metasomal segments of same color as the tergites. Vesicle reddish yellow with basis of aculeus reddish and tip of aculeus reddish black. Chelicerae yellowish with longitudinal brown spots; basis of fingers and fingers dark brown. Pedipalps reddish with diffuse and reticular light brown spots on femur and patella. Legs yellowish with diffuse light brown spots. Carapace slightly emarginated, almost straight; almost smooth, with few minute granules only on lateral areas. Tergites almost smooth, with scattered minute granulations. Pectinal tooth count ranging from seven to nine in male and 7-7 in female. Sternites smooth; spiracles oval to round in shape. All metasomal segments with dorsal and latero-dorsal carinae well-marked; other carinae weakly marked or absent; segment V with spinoid granulations ventrally. Vesicle flattened, moderately granular; aculeus of moderate size compared to vesicle. Pedipalp femur with four well-marked carinae; patella with three carinae, chela with two carinae; femur and patella feebly granulated; chela well granulated on dorsal and internal sides, with granules arranged in four longitudinal wide series on external side; fingers about the same length as the chela and with dentate margins on movable fingers with six rows of granules, separated by stronger accessory granules.
