Etymology. The specific epithet, a noun in genitive, honors arachnologist Dr. Wayne P. Maddison, who helped us plan the project for the revision of Anicius and collected several of the new species described herein.
Diagnosis. Live specimens have a metallic green luster (Figs 11–12). Males differ from other species by the presence on the abdomen of two pairs of lateral semi-triangular spots, one pair of distal dark spot (Fig. 56) and dorsally darker green colored (Fig. 11). Male palp resembles that of A. dolius Chamberlin and A. faunus sp. nov. by the thin and long embolus, but differs from those species by the TL, which is square and has no crests. Additional differences with the other species of Anicius include the triangular chelicera of the males, and the female leg I with femur brown and the remaining articles yellow (Fig. 12).
Description. Male (holotype CNAN-T 1104). Total length: 4.20. Prosoma: 2.00 long, 1.40 wide, 0.90 high. Opisthosoma: 2.20 long. Eye field: 0.90 long, anterior width 1.20, posterior width 1.20.

Body coloration: specimens in alcohol turn to a brownish yellow color with metallic scales. Carapace dark brown, with a white band of setae around the lateral margins of the carapace and across the clypeus (Figs 54, 56), abdominal white bands followed by two pairs of white spots and a pair of dark spots (Fig. 56). Chelicera: triangular, brown, the promargin with a medial projection, above this projection a conspicuous apical tooth and below a small subapical tooth, retromargin with a bicuspid tooth as large as apical promarginal tooth. Legs: I dark brown, stouter and longer than the other legs; II–IV thin, pale-yellow with darker spots (Figs 11, 54–56). Opisthosoma: dorsally deep dark brown, ventrally with a very wide dark colored band, and two thin submedian longitudinal stripes (Fig. 55).

Differences with the male: Legs: leg I stouter and longer than the other legs, femur brown; II–IV thin and pale-yellow (Figs 57–59). Palp: yellow. Opisthosoma: wider than on males, the ventral longitudinal dark band well-defined (Fig. 58). Epigyne: simple, CD with the convergent-divergent pattern (Figs 88–89).
Variation. Males (n = 9). Total length: 2.50–4.20. Prosoma: 1.30–2.00 long, 1.30–1.60 wide. 0.70–0.90 high. Opisthosoma: 1.20–2.20 long, 0.80–1.20 wide. Eye field: 0.70–0.90 long, anterior width 0.90–1.20, posterior width 0.90–1.20. Cheliceral length 0.40–0.70. Females (n = 11). Total length: 3.10–4.20. Prosoma: 1.40–1.60 long, 1.10– 1.30 wide. 0.60–0.70 high. Opisthosoma: 1.70–2.60 long, 1.00–1.70 wide. Eye field: 0.60–0.80 long, anterior width 0.90–1.00, posterior width 0.90–1.00. Cheliceral length 0.40–0.50. Some males do not present the darker spot (n = 3). Some females (n = 5) do not have the medial longitudinal darker band on opisthosoma well defined. One female from Naolinco has leg I with femur to metatarsus brown and tarsus yellow.
Natural history. Specimens were found during at the day wandering on trees, in a fragmented oak forest (Fig 23). Adult specimens were found from June to October, during the rainy season.
Distribution. Puebla and Veracruz, Mexico (Fig. 17).
