Etymology. The specific name, a noun in genitive, is dedicated to acarologist Griselda Montiel Parra, nicknamed “Gris”, who helped collect the holotype.

Diagnosis. Live specimens have a metallic green luster, and differ from other Anicius   species in the number of lateral abdominal spots, two dark spots and two white spots ( Figs 9–10 View FIGURES 1–12 ), A. grisae   has four pairs of spots ( Fig 10 View FIGURES 1–12 ). The male palp resembles A. cielito   but A. grisae   differs from the other Anicius   species by the presence of a keel in the promargin of the embolus ( Fig 76 View FIGURES 72–77 ), TL bilobed with two marginal crests and the bulb is kidney-shaped ( Figs 68 View FIGURES 60–71 , 76 View FIGURES 72–77 ). Females of A. grisae   resembles A. cielito   in leg I color pattern, but differs from it in the general shape of the epigyne, A. grisae   has the CD with the convergent-divergent pattern ( Fig 86 View FIGURES 78–89 ).

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 48, 50 View FIGURES 48–53 ), abdominal white bands followed by four pairs of spots, first and third white, second and fourth darker ( Fig. 9 View FIGURES 1–12 ). Chelicera: as described for the genus ( Fig. 15 View FIGURES 13–16 ). Legs: I dark brown, stouter and longer than the other legs; II–IV thin and pale-yellow. Opisthosoma: ventrally with a very wide dark colored band and two thin submedian longitudinal stripes ( Fig. 49 View FIGURES 48–53 ). Palp: dark brown; embolus short and stout and curved less than 75°, but more than 70° ( Fig. 76 View FIGURES 72–77 ); TL with two triangular crest as long as wide, the base of the bulb more extended to the retromarginal side than the rest of the bulb ( Figs 68, 69 View FIGURES 60–71 , 76 View FIGURES 72–77 ); RTA like a flattened spine.

IV: Fm d 1-1-1; Mt p 0-0-1, r 0-0-1. Differences with the male: Legs: leg I stouter and longer than the others, brown with tarsus and metatarsus yellow; II–IV thin and pale-yellow ( Fig. 10 View FIGURES 1–12 ). Palp: yellow. Epigyne: simple, CD with the convergent-divergent pattern ( Figs 86–87 View FIGURES 78–89 ).

Variation. Males (n = 14). Total length: 3.40–4.00. Prosoma: 1.70–2.00 long, 1.00–1.70 wide. 0.60–0.80 high. Opisthosoma: 1.80–2.10 long, 1.00–1.30 wide. Eye field: 0.70–0.90 long, anterior width 1.00–1.20, posterior width 1.00–1.20. Cheliceral length 0.50–0.70. Females (n = 34) Total length: 3.60–4.00. Prosoma: 1.50–1.80 long, 1.20– 1.40 wide. 0.60–0.70 high. Opisthosoma: 1.90–3.10 long. Eye field: 0.70–0.80 long, anterior width 1.00–1.10, posterior width 1.00–1.10. Cheliceral length 0.40–0.50. Some specimens (n = 4) do not have the medial longitudinal dark band on opisthosoma well-defined, or have just one pair of dark lateral spots (n = 6). Some males have blunt, instead of bicuspid retromarginal tooth (n = 8).

Natural history. Specimens were found during the day in mixed oak-pine forests wandering on trees, between 1,500 to 2,500 m elevation ( Fig. 22 View FIGURES 18–23 ). This species has a greater abundance of adults during spring and summer; May is the best month to collect adult males and June to collect pregnant females. Five females were collect in June in Oaxaca, three of them, laid egg sacks seven days later, with 11– 13 eggs each. Females showed parental care, stay- ing close to the egg sack and keeping their legs over the egg sac most of the time. After eight weeks, six spiderlings emerged from one of the egg sacks, and they died a few days later. The other two females died two weeks after its recollection and their egg sacks rotted a few days later.

Distribution. Estado de México, Guerrero, Morelos and Oaxaca, Mexico ( Fig. 17 View FIGURES 17 ).
