Etymology. The epithet, to be treated as an adjective, refers to the state of Chiapas, where the type locality is located.

Diagnosis. Live specimens have a metallic green luster, the abdomen with one pair of dark lateral spots and two pairs of lateral white spots ( Figs 3–4 View FIGURES 1–12 ). Anicius chiapanecus resembles A. grisae sp. nov. and A. cielito sp. nov. by the embolus short and stout, but males of A. chiapanecus can be distinguished by the combination of a rectangular and large TL without crests and the embolus strongly curved or “C”-shaped ( Figs 60, 61 View FIGURES 60–71 , 72 View FIGURES 72–77 ). Females are recogniz- able by the epigyne with a triangle formed by the anterior part of CD ( Figs 78–79 View FIGURES 78–89 ).

Length of leg segments: I 1.05 + 0.60 + 0.85 + 0.65 + 0.40 = 3.55; II 0.80 + 0.40 + 0.50 + 0.45 + 0.30 = 2.45; III 0.70 + 0.30 + 0.45 + 0.50 + 0.35 = 2.30; IV 0.90 + 0.40 + 0.60 + 0.55 + 0.45 = 2.90.

Body coloration: specimens in alcohol turn to brownish with metallic scales. Carapace dark brown with a white band of setae around lateral margins of carapace and across the clypeus ( Figs 30, 32 View FIGURES 30–35 ), abdominal white bands followed by one pair of white spots and one pair of dark spots ( Figs 3 View FIGURES 1–12 , 32 View FIGURES 30–35 ). Chelicera: as described for the genus ( Fig. 15 View FIGURES 13–16 ) with a large bicuspid tooth. Legs: I dark brown, stouter and longer than the other legs, II–IV thin and pale-yellow with darker spots ( Fig. 3 View FIGURES 1–12 ). Opisthosoma: ventrally with a very wide dark colored band and two thin submedian longitudinal stripes ( Fig. 31 View FIGURES 30–35 ). Palp: brown, embolus short, stout and curved approximately 70° ( Figs 60–61 View FIGURES 60–71 , 72 View FIGURES 72–77 ); TL rectangular without crests; bulb oval, longer than wide ( Fig. 61 View FIGURES 60–71 ); RTA like small and stout spine.

Differences with the male: Legs: leg I stouter and longer than the other legs, femora dark brown the other articles brown; II–IV thin and pale-yellow ( Figs 33–35 View FIGURES 30–35 ). Palp: yellow. Epigyne: CD simple, convergent-divergent pattern, poorly chitinized ( Figs 7 8–79 View FIGURES 1–12 View FIGURES 13–16 View FIGURES 17 View FIGURES 18–23 View FIGURES 24–29 View FIGURES 30–35 View FIGURES 36–41 View FIGURES 42–47 View FIGURES 48–53 View FIGURES 54–59 View FIGURES 60–71 View FIGURES 72–77 View FIGURES 78–89 ).
