Etymology: The species epithet is the toponymic derived from the type locality, the Orizaba volcano. It is a declinable adjective.

Diagnosis: Males of S. orizabae are similar to those of S. izactepetl differing by having the RCm curved inwards, with an arrow-like end ( Figs 24H, 32B). DSA similar to the S. longispinosus but thinner ( Fig. 24F, G). Females of S. orizabae have the copulatory openings surpassing the midpoint of the epigynum ( Figs 25E, 36B) instead of being restricted to the anterior part as its congeners. COs dividers with slightly curved outward lateral lines and posterior edge slightly curved posteriorly (concavity down; Figs 25E, 36B).

Description: Male (holotype TSM 628) Total length 2.35. Prosoma 0.93 long, 0.85 wide. Prosoma height 0.79, fovea height 0.77. Opisthosoma 141 long, 0.69 wide, 0.77 high. Clypeus height 0.16.AME 0.04, ALE 0.05, PME 0.05, PLE 0.05. Femur I 2.58 (2.76× prosoma length), Metatarsus I 3.69, TmI 0.12. Prosoma dark yellow, with a darker line separating the cephalic area from the carapace and in the margins of the prosoma. Opisthosoma light grey with lateral white guanine spots and dark marks on the dorsum. Legs same colour as the prosoma, without any marks ( Fig. 24A–D). Tegular apex triangular, with an ectal round projection facing downward.

Female (paratype). Total length 1.97. Prosoma 0.88 long, 0.76 wide. Prosoma height 0.81, fovea height 0.69. Opisthosoma 1.09 long, 0.93 wide, 1.51 high. Clypeus height 0.14. AME 0.04, ALE 0.04, PME 0.06, PLE 0.06. Femur I 2.10 (2.38× prosoma length), Metatarsus I 2.66, TmI 0.13. Prosoma dark yellow, with a darker line separating the cephalic area from the carapace and in the margins of the prosoma. Opisthosoma light grey dorsal black spot covers the entire dorsum. Legs same colour as the prosoma, without any marks ( Fig. 25A–D). Spermatheca ventroposteriorly positioned ( Fig. 25E, F). Pre-chamber opens ventrally ( Fig. 25G).
