Figures 52–57
Type. Female (Holotype): MEXICO: Baja California Sur, Municipality of La Paz, Biosphere Reserve Sierra La Laguna, Paso de Golondrina, 1640 m, 13.I.1988, V. Roth (CARCIB 1249), deposited at CARCIB.
Etymology. The specific name is a noun in apposition taken from the type locality.
Diagnosis. R. golondrina differs from R. griswoldi by having concave (vs. straight) mesal hood margins (Figs. 52, 53), from R. cochimi and R. pilar by having the hoods covering more than half the length of the plate (Figs. 52, 53), from R. sudcaliforniensis and R. naranjensis by having the spurs not exceeding the epigastric furrow (Fig. 53).
Description. Female (holotype): Coloration. Prosoma with a black band around the border of thoracic region, and two longitudinal symmetric darkener bands on carapace. Chelicerae reddish, condyles yellow, sternum dark orange with black diffuse spots at sides, endites and labium dark orange with white tips. Legs with rings: three in femur, two in tibia. Coxa IV with a diffuse spot in proximal part. Opisthosoma with a anterior dorsal brown spot and with two lateral white bands, which are connected to form a broad foliage band surrounded by five pairs of black spots. There are diffuse black spots lateral and ventrally. Posterior lateral spinnerets with longitudinal black spots in basal segment and proximal part of distal segment. Habitus. Total length 7.88. Carapace length 3.5, width 2.38, cephalic region width 1.29, ocular region width 0.62. Eye rows strongly procurved. Eye diameter: AME 0.12, ALE 0.15, PME and PLE 0.13. Distance between eyes: AME-AME 0.08, AME-ALE 0.06, AME-PME 0.13, ALE- PLE 0.06, ALE-ALE 0.27, PME-PME 0.1, PME-PLE 0.08. Clypeus height 0.13. Chelicerae: basal segment length 1.06, fang length 0.21. Labium wider than long (0.52/0.45). Endites slightly convergent (distance at their base compared with that at their tips 0.52/0.42). Sternum longer than wide (1.81/1.11). Opisthosoma longer than wide (4.63/2.6). Anterior lateral spinnerets separated by slightly less their basal diameter (0.29/0.33), posterior lateral spinnerets with distal segment longer than basal segment (0.94/0.66). Legs. Relation prosoma/patella-tibia I: 3.5/ 3.57. Legs length: I—femur 2.76/ patella-tibia 3.57/ metatarsus 2.48/ tarsus 1.81; II—2.76/ 3.29/ 2.38/ 1.62; III— 2.76/ 3.24/ 2.62/ 1.62; IV—3.38/ 4.1/ 3.86/ 2. Spination. Femur dorsal I—1-1 -1-1/ II—1-2 -1-1/ III—1-1 -1-2/ IV— 1-1 -1-2; patella dorsal I—1-2 -1/ II—1-2 -1/ III—1-2 -1/ IV—1-2 -1; tibia I—dorsal 1-0-0/ ventral 2-2-2/ prolateral 1-1-0/ retrolateral 0; II—1 / 1-2-2/ 0-1-1/ 0; III—1-1 -0/ 2-2-2/ 1-1-0/ 1-1-0; IV—1-1 -0/ 2-1-1-2/ 1-1-0/ 1-1-0; metatarsus I—0/ 2-2-1/ 0-1-1/ 0-1-1; II—0/ 1-2-2/ 1-1-0/ 1-1-0; III—3-1 -2/ 2-2-2/ 0-1-1/ 0-1-1; IV—3-2 -2/ 1-1-1- 2-2/ 0-1-1/ 0-1-1. Number of trichobothria in tarsus: I—6, II—6, III—4, IV—5. Pedipalp. Number of dorsal spines: femur 2, patella 2, tibia 4. Epigynum (Figs. 52–57). Hoods as long as the half of the plate length, covering half of atrium and wider in posterior part. Anterior part of copulatory ducts separated by less than their width. Spermathecae separated by more of their diameter almost touching the ventral margin in posterior view. Plate wider than long (0.88/0.61).
Male: Unknown.
Habitat. The specimen was collected on the ground surface of a pine-oak forest dominated by Pinus lagunae (laguna mountain pinyon, pino piñonero), Quercus tuberculata (cape red oak, encino roble), Arbutus peninsularis (peninsular madrone, madroño) and Mimosa xanti (xantus mimosa, celosa) (Wiggins 1980, Rebman & Roberts 2012).
Distribution. Biosphere Reserve Sierra La Laguna, Municipality of La Paz, Baja California Sur, Mexico (Fig. 7).
