Types. Holotype: male (CNAN-T 01041) from San Sebastían del Oeste, road to Cerro de “ La Bufa ” (20.7495 ° N, 104.8283 ° W, 1681 m), Jalisco, Mexico, 28. VI. 2016, D. Guerrero-Fuentes, G. Contreras-Felix, G. Montiel-Parra & L. Olguín leg. Paratypes: 2 ♀ (CNAN-T 01042), same data as holotype. Additional material examined. MEXICO, Jalisco: 3 ♀ (CNAN-Ar 011161), same locality as types, 12. IX. 2017, D. Guerrero, G. Montiel, R. Paredes & I. Salgado leg.; 2 ♁, 2 ♀ (CNAN-Ar 011162), same locality as types, 14. VI. 2018, D. Guerrero, G. Contreras & J. Arreguin leg. Etymology. The epithet is a noun in apposition, and refers to the faunus in the Roman mythology, a fantastic creature who lived in the woods, the usual habitat of Anicius species. Diagnosis. This species resembles A. cielito sp. nov. in general color pattern (Figs 7 – 8), but we can distinguish A. faunus from the remaining species of Anicius by the male genitalia: A. faunus has a needle-shaped embolus, similar to A. dolius Chamberlin and A. maddisoni sp. nov., but differs from those because the embolus is straight or less curved (Figs 66, 75), and TL has a triangular retromarginal crest (Fig. 67). The female has brown leg I with yellow tarsus (Fig. 47). Description. Male (holotype CNAN-T 01041). Total length: 4.50. Prosoma: 2.10 long, 1.60 wide and 0.70 high. Opisthosoma: 2.40 long, Eye field: 1.00 long, anterior width 1.40, posterior width 1.40. Cheliceral length 0.50. Length of leg segments: I 1.50 + 0.80 + 1.00 + 0.90 + 0.50 = 4.90; II 1.00 + 0.50 + 0.70 + 0.60 + 0.40 = 3.20; III 1.00 + 0.50 + 0.50 + 0.60 + 0.40 = 3.00; IV 1.20 + 0.50 + 0.80 + 0.80 + 0.40 = 3.70. Leg spination: I: Fm d 1 - 1 - 1, p 0 - 0 - 2; Pt p 0 - 1 - 0; Tb v 2 - 2 - 2; Mt v 0 - 2 - 2. II: Fm d 1 - 1 - 1, p 0 - 0 - 2, r 0 - 0 - 1; Tb v 1 - 1 - 2, p 0 - 1 - 1; Mt v 0 - 1 - 2. III: Fm d 1 - 1 - 1, p 0 - 0 - 2, r 0 - 0 - 1; Tb v 0 - 0 - 1, p 0 - 1 - 0, r 0 - 1 - 1; Mt p 0 - 0 - 2, r 0 - 0 - 2. IV: Fm d 1 - 1 - 1, p 0 - 0 - 1, r 0 - 0 - 1; Tb v 1 - 0 - 2, p 0 - 1 - 0; Mt pl 0 - 1 - 2, r 0 - 0 - 1. 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 42, 44). Abdominal white bands followed by one pair of white spots and a pair of dark spots (Figs 7, 42, 44). Chelicera: triangular and brown, as described for the genus. Thoracic area: as described for the genus (Figs 43, 46). Legs: I dark brown, stouter and longer than the other legs; II – IV thin, pale-yellow with darker spots (Figs 7, 42 – 44). Opisthosoma: dorsally deep dark brown (Figs 42 – 44). Palp: Embolus granulated (Fig. 75), large and thin, slightly curved at 75 ° (Fig 66 – 67, 75); TL rectangular with a triangular crest, bulb oval, longer than wide (Figs 66 – 67); RTA hook-like. Female (paratype CNAN-T 01042). Total length: 4.30. Prosoma: 1.70 long, 1.30 wide, 0.70 high. Opisthosoma: 2.60 long. Eye field: 0.70 long, anterior width 1.00, posterior width 1.00. Chelicera length 0.40. Length of segments: I 0.80 + 0.40 + 0.55 + 0.40 + 0.30 = 2.60; II 0.60 + 0.35 + 0.40 + 0.35 + 0.30 = 2.00; III 0.60 + 0.40 + 0.40 + 0.30 + 0.30 = 1.95; IV 0.80 + 0.40 + 0.50 + 0.40 + 0.35 = 2.55. Leg spination: I: Fm d 1 - 1 - 1, p 0 - 0 - 2; Tb v 2 - 2 - 2; Mt v 0 - 2 - 2. II: Fm d 1 - 1 - 1, p 0 - 0 - 2; Tb v 1 - 1 - 2, p 0 - 0 - 1; Mt p 0 - 1 - 1, r 0 - 0 - 1.

IV: Fm d 1 - 1 - 1, p 0 - 0 - 1, r 0 - 0 - 1; Tb v 1 - 0 - 1, p 0 - 1 - 0; Mt p 0 - 0 - 2, r 0 - 0 - 1. Differences with the male: Legs: I stout and slightly longer than IV, dark brown with yellow tarsus (Figs 45 – 47); II – IV yellow without markings (Fig. 45). Palp: yellow. Opisthosoma: noticeably wider than in male (Figs 45 – 47). Epigyne: simple, CD with the convergent-divergent pattern, and with three loops (Figs 84 – 85). Variation. Males (n = 3). Total length: 3.60 – 4.60. Prosoma: 1.70 – 2.10 long, 1.00 – 1.60 wide. 0.70 – 1.00 high. Opisthosoma: 1.90 – 2.50 long, 1.10 – 1.20 wide. Ocular quadrangle: 0.80 – 1.00 long, anterior width 1.00 – 1.20, posterior width 1.00 – 1.20 wide. Females (n = 7). Total length: 3.50 – 4.30. Prosoma: 1.60 – 1.80 long, 1.30 wide. 0.70 high. Opisthosoma: 1.70 – 2.60 long, 1.60 – 1.90 wide. Ocular quadrangle: 0.70 long, anterior width 1.00, posterior width 1.00. Some females (n = 4) do not have the medial longitudinal darker band well-defined. One male has a single-cuspid retromarginal tooth instead bicuspid, visibly torn due aging. Natural history. Specimens were found during the day wandering on trees in pine-oak forest (Fig. 21). Distribution. Only known from type locality (Fig. 17).
