Mesosoma about as wide as head width; mesoscutum 1.5x wider than long, 2.4x longer than mesoscutellum, 4.2x longer than metanotum; propodeum with basal part about 0.9x mesoscutellum length in dorsal view; protibial spur with apical portion of rachis long, about as long as malus, with four elongate branches (not including apical portion of rachis); mesotibial spur straight, with coarse branches, 0.8x mesobasitarsus length; metatibial spurs about the same length, curved apically; pretarsal claws with inner ramus slightly shorter than the outer.
Their body is dark brown, with a bluegreen metallic shine, mainly on the head and mesosoma, with a yellowish color at the basal antenna joints and brown legs (MENDEL et al., 2004).

are identified by 12-segmented antennae, fewer than 10 mandibular denticles or teeth, antennal sockets almost abutting the posterior clypeal margin, long and conspicuous maxillary palps, coarse and erect hairs on the head and mesosoma, short and compact mesosoma without constriction of the mesonotum, and absence of erect setae on the propodeum.
Tergum I polished and striated longitudinally; remaining tergum smooth and polished, with disperse setae and just along the division of terga (Figure 3a); ovipositor sheaths densely setose; ovipositor 0.8 times the length of mesosoma.
Since all parts of its body such as pedipalps, dorsal surface of mesosoma, legs, lateral and ventral surfaces of metasomal segments, and vesicle densely are covered by hair, it is known as the hairy black scorpion.
The majors and minors are darker, bicolored, with the head and gaster dark brown, and the mesosoma and legs reddish brown.
