Types. Holotype: male ( CNAN-T1098 ) from Gómez Farías , Alta Cima (23.0607°N, 99.2152°W, 1067 m), Reserva de la Biosfera El Cielo, Tamaulipas, Mexico, 22.IV.2016, D. Guerrero, J. Arreguin, G. Montiel, R. Monjaraz, G. Contreras, J. Cruz & J. Olivos leg. GoogleMaps Paratypes: 1 ♁ and 3 ♀ ( CNAN-T1099 ), same data as holotype GoogleMaps .

Additional material examined: MEXICO: Tamaulipas: 1 ♁ ( MCZ 134003 View Materials ) ; 1 ♀ ( MCZ 134004 View Materials ), same data as types .

Etymology. The species name is a noun in apposition; a diminutive dedicated to the type locality Reserva de la Biosfera “El Cielo”.

Diagnosis. Live specimens with metallic green luster ( Figs 5–6 View FIGURES 1–12 ). A. cielito resembles to A. faunus sp. nov. in the number of lateral abdominal spots, first pair white and second darker ( Figs 6 View FIGURES 1–12 , 38 View FIGURES 36–41 ), but differs from that species in the male genitalia. The male palp of A. cielito is similar to A. grisae sp. nov. and A. chiapanecus sp. nov., but differs from this species because the embolus in A. cielito is less curved than in A. chiapanecus and does not have the prolateral keel present in A. grisae ; the bulb and TL are similar to A. chiapanecus , bulb is oval and TL is rectangular without crests ( Figs 62, 63 View FIGURES 60–71 ). Females are recognizable by the epigyne with CD straight ( Fig 8 View FIGURES 1–12 0–81).

Body coloration: specimens in alcohol turn to a brownish yellow color with metallic scales. Carapace dark brown with a white band of setae around lateral margins of carapace and across the clypeus ( Figs 36, 38, 41 View FIGURES 36–41 ), abdominal white bands followed by two pairs of spots, first white and second darker ( Figs 36, 38 View FIGURES 36–41 ). 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 with darker spots. Opisthosoma: ventrally with a very wide dark colored band, and two thin submedian longitudinal stripes ( Fig. 37 View FIGURES 36–41 ). Palp: brown; embolus smooth, short, stout and curved 75° ( Figs 62–63 View FIGURES 60–71 , 73 View FIGURES 72–77 ); TL rectangular, straight without crests, bulb oval, longer than wide ( Fig. 63 View FIGURES 60–71 ); RTA like small and stout spine.

Differences with the male: Legs: leg I stouter and longer than the other legs, brown with only tarsus and metatarsus yellow; II–IV thin and pale-yellow ( Figs 39–41 View FIGURES 36–41 ). Palp: yellow. Epigyne: simple, internally CD longitudinal ( Figs 80–81 View FIGURES 78–89 ).

Variation. Males (n = 3). Total length: 3.10–4.10. Prosoma: 1.40–1.90 long, 1.00–1.40 wide, 0.80 high. Opisthosoma: 1.70–2.20 long. Eye field 0.80 long, anterior width 1.10, posterior width 1.10. Cheliceral length 0.50–0.70. Females (n = 4). Total length: 3.00–4.10. Prosoma: 1.40–1.80 long, 1.10–1.40 wide, 0.70–0.80 high. Opisthosoma: 1.60–2.30 long. Eye field: 0.80 long, anterior width 1.10, posterior width 1.10. Cheliceral length 0.40–0.50. Some males have on chelicera a single-cuspid retromarginal tooth (n = 2).

Natural history. Specimens were found during the day in a cloud forest, wandering on shrubs and lower leaves of oak trees at 1,065 m elevation ( Fig. 18 View FIGURES 18–23 ). Mating dance of a male was observed: male stood in front of a female, raised his first pair of legs and moved from side to side, while simultaneously moving the abdomen up and down. Other movements of mating dance of Anicius were recorded by Maddison (1996).

Distribution. Known only from the type locality ( Fig. 17 View FIGURES 17 ).
