Anicius cielito Guerrero-Fuentes & Francke 2019, sp. nov.

Anicius cielito sp. nov. Figs 5–6, 36–41, 62–63, 73, 80–81 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. Paratypes: 1 ♁ and 3 ♀ (CNAN-T1099), same data as holotype. Additional material examined: MEXICO: Tamaulipas: 1 ♁ (MCZ 134003); 1 ♀ (MCZ 134004), 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). A. cielito resembles to A. faunus sp. nov. in the number of lateral abdominal spots, first pair white and second darker (Figs 6, 38), 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). Females are recognizable by the epigyne with CD straight (Fig 8 0–81). Description. Male (holotype CNAN-T 1098). Measurements: Total length: 3.90. Prosoma: 1.80 long, 1.00 wide, 0.80 high.

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), abdominal white bands followed by two pairs of spots, first white and second darker (Figs 36, 38). Chelicera: as described for the genus (Fig. 15). 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).

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). Palp: yellow. Epigyne: simple, internally CD longitudinal (Figs 80–81). 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.

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). 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).Published as part of Guerrero-Fuentes, Dariana R. & Francke, Oscar F., 2019, Taxonomic revision of Anicius Chamberlin, 1925 (Araneae: Salticidae), with five new species of jumping spiders from Mexico, pp. 485-506 in Zootaxa 4638 (4) on pages 491-492, DOI: 10.11646/zootaxa.4638.4.2, http://zenodo.org/record/334043
