S. asperatus can be distinguished from the latter species by the combination of the following characters: lateral margin of dorsal scutum covered by granules; trochanter IV with a blunt retro-dorsal apical apophysis being half of the podomere length, and a rhombus retro-ventral apical tubercle; femur IV curved (in dorsal view), with a retro-lateral row of spiniform apophysis (the middle one longest). Redescription. Male (CAS 9055035). Measurements. Dorsal scutum maximum length 6.3; dorsal scutum maximum width 7.2; prosoma maximum length 2.5; prosoma maximum width 3.2; leg femora I 3.2; II 6.5; III 5.5; IV 7.2. Dorsum (Fig. 3A ). Dorsal scutum type gamma triangular. Carapace with granules sparsely distributed. Scutal areas I-IV with eight, four, two and four granules, respectively; scutal area III with one pair of paramedian spiniform tubercles; scutal area IV incompletely divided. Lateral margin of dorsal scutum mostly covered in granules (from posterior half of carapace to posterior margin of dorsal scutum). Posterior margin of dorsal scutum and free tergite I each with a pair of paramedian tubercles. Chelicerae . Segment I with basal tubercle, bulla with small setae, each finger with five teeth. Pedipalps . Coxa dorsal face smooth, ventral face with two apical tubercles. Trochanter dorsal and ventral faces smooth. Femur ventral face granulate. Patella with sparsely distributed setae. Tibial setation: prolateral IiiiIi/IiiiIi; retro-lateral iIiIi/IiIi. Tarsal setation: prolateral and retro-lateral IiIi/IiIi. Legs (Fig. 3B-E ). Coxa IV with one long, oblique, bifid prodorsal apical apophysis and one retro-ventral apical spine. Trochanters I and II each with one pair of prodorsal spiniform tubercles. Trochanter III with one medio-ventral tubercle and three retro-lateral ones. Trochanter IV prodorsal and proventral faces with few granules, the prodorsal apical apophysis long (ca. half the podomere length); retro-lateral face with one basal, one central, and one apical tubercles; one retro-dorsal apical spiniform apophysis (ca. 1/4 podomere length); ventral face with setiferous tubercles sparsely distributed. Femur III with one retro-basal tubercle. Femur IV sigmoid, with dorsal row of apophysis on the basal half abruptly decreasing in size apically, becoming granules; prolateral row with central-subapical tubercles; retro-lateral row of granules with spiniform apophysis (basal most and central one longer than the others, apical most oblique, curved ventrad); ventral face with two short retro-lateral sub-apical spiniform apophyses and one proapical spiniform apophysis. Patella IV ventral face mostly smooth, with one probasal, one proapical and one retro-apical large, spiniform tubercles. Tibia IV roughly with two ventral rows of granules increasing in size from central to apical becoming spines. Tarsal counts: 6, 9, 7, 8. Penis (Fig. 11A, B ). Ventral plate of penis with moderate cleft on anterior margin, three pairs of MS A, one pair of MS B, four or five pairs of MS C and one pair of MS D, without MS E. Coloration . Immersed in ethanol: carapace, trochanter-patella IV brown, tibia light brown, legs I-III, pedipalps, and chelicerae yellowish-brown. Live specimens (Fig. 9A-C, E ): carapace, coxa, and trochanter black, light gray spot (inverted T shape) from ocularium to scutal area II; femora I-III orange; patellae-tibiae I-IV brown. Variations (n = 56). Scutal area I-IV tubercles (5 minimum, 16 maximum per site), Measurements. Dorsal scutum maximum length 6.0-8.5; dorsal scutum maximum width 6.7-11.6; prosoma maximum length 2.5-3.5; prosoma maximum width 3.2-4.8; leg femora: I 3.2-5.0; II 6.5-10.0; III 5.5-8.5; IV 7.2-11.0. Female (CAS 9055035). Measurements. Dorsal scutum maximum length 6.3; dorsal scutum maximum width 8.1; prosoma maximum length 2.6; prosoma maximum width 3.7; leg femora: I 3.7; II 7; III 6.1; IV 7.2. Redescription. Dorsum (Fig. 8A, B ). Scutal areas I, II, and IV with three, five, and two granules, respectively. Legs . Coxa IV with one prodorsal apical apophysis and one retro-ventral apical spine shorter than on the male, trochanter IV with retro-lateral row of tubercles, the apical one longest, femur IV with pro- and retro-ventral rows of tubercles, patella-metatarsi IV unarmed. Tarsal counts: 6, 9, 7, 8. Ovipositor (Fig. 12A-C ). Two main groups of lobes delimited by a constriction, ovipositors peripheral setae inserted into sockets that are a mixture of dorsal and ventral sockets, the dorsal lobe with five setae and the ventral one with six; each main group of lobes divided by a fissure. Variations (n = 66). Tubercle variation in the scutal areas: I 2-7; II 1-8; III 2-8; IV 3-5. Free tergites I-III each with one pair of blunt or pointed spiniform tubercles. Measurements. Dorsal scutum maximum length 5.9-8.2; dorsal scutum maximum width 8.0-9.6; prosoma maximum length 2.4-3.5; prosoma maximum width 3.7-4.5; leg femora: I 3.5-4.5; II 6.7-8.7; III 5.7-7.0; IV 7.0-8.9.

Taxonomic notes. After examining the original description and the drawing of Gonyleptes bicornis , we concluded that it is of a male of S. asperatus . In the original description, the spines on the free tergite, the two apical apophyses on the trochanter IV and uneven spines in the inner part of the "leg" (referring to the femur IV) are mentioned. Those characters lead us to conclude that it is S. asperatus .
