DIAGNOSIS: In having relatively large eyes, members of this species resemble only those of P. orellana   . Males of P. cupida   have a much longer embolar base (fig. 190); females have shorter apodemes (fig. 199).

MALE (PBI_OON 476, figs. 185–192): Total length 2.34. Carapace orange-brown, without any pattern; surface of elevated portion of pars cephalica finely reticulate, sides granulate. ALE separated by their radius to diameter, PLE-PME separated by less than PME radius. Sternum orange-brown, surface finely reticulate. Chelicerae, endites, and labium orange-brown. Abdomen cylindrical; dorsum soft portions white. Dorsal scutum orange-brown, without color pattern but with reticulate surface; postepigastric scutum orange-brown. Legs orange-brown, without darkenings. Palp pale orange; femur enlarged, attaching to patella subbasally, patella longer than femur, enlarged; embolar base with narrow extension, embolus accompanied basally by wide conductor.

FEMALE (PBI_OON 476, figs. 193–199): Total length 2.55. Abdominal dorsum white, without color pattern. Anterior genitalic ducts with long longitudinal ventral portion followed distally by transverse coils; apodemes short, widely separated.

DISTRIBUTION: Known only from paramo habitats at elevations of 3200–3367 m near Bogotá, Colombia   .

Pescennina magdalena   , new species

Figures 200–214

TYPES: Male holotype and female allotype taken at Tayrona-Park, Bahía de Cinba, western beach, ca. 35 km E of Santa Marta, Magdalena, Colombia (Apr. 1986; H. Müller), deposited in MHNG (PBI_ OON 10506 View Materials )   .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males have a long, narrow right prong on the embolar base that reaches about half the length of the bifid middle prong (fig. 205); females have a short, wide posterior receptaculum, and a sinuous transverse bar connecting the apodemes (figs. 213, 214).

MALE (PBI_ OON 10506 View Materials , figs. 200–207): Total length 1.78. Carapace pale orange, without any pattern; surface of elevated portion of pars cephalica finely reticulate, sides finely reticulate. ALE separated by their radius to diameter, PLE-PME separated by more than PME diameter. Sternum pale orange, surface rugose. Chelicerae, endites, and labium yellow. Dorsal scutum orange-brown, without color pattern, with deep depression just behind anterior margin; postepigastric scutum orange-brown. Femora I, II with basal darkening on prolateral surface, longitudinal darkening on ventral surface; III, IV with basal portion unmarked but with prolateral and retrolateral sides darkened; patellae IV distally darkened; tibiae IV ventrally darkened. Palp yellow-brown; embolar base with long, spiniform, right prong, embolar tip highly coiled.

FEMALE (PBI_ OON 10506 View Materials , figs. 208–214): Total length 1.86. Abdominal dorsum gray with anterior, median, and posterior transverse white stripes; postepigastric scutum yellow. Anterior genitalic ducts with transverse duct medially narrow, almost as wide as posterior receptaculum; posterior receptaculum short, wide, posteriorly invaginated.

Pescennina sasaima   , new species

Figures 215–229

TYPE: Male holotype taken in open-air patio on roof posts at Finca Bella Vista, near Sasaima, Cundinamarca, Colombia (Apr. 15, 1965; P., D. Craig), deposited in CAS (PBI_ OON 46492 View Materials )   .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males have two short right prongs on the embolar base, one situated proximally, the other at about half the length of the base (fig. 220); females have a short posterior receptaculum and winglike extensions on the sides of the transverse bar connecting the apodemes (figs. 228, 229).

MALE (PBI_ OON 46492 View Materials , figs. 215–222): Total length 1.74. Carapace orange-brown, without any pattern; surface of elevated portion of pars cephalica smooth, sides striated. ALE separated by their radius to diameter, PLE-PME separated by more than PME diameter. Sternum pale orange, surface rugose. Chelicerae, endites, and labium pale orange. Dorsal scutum orange-brown, without color pattern, deeply depressed immediately behind anterior margin; postepigastric scutum pale orange. Femora I, II with basal darkening on prolateral surface, longitudinal darkening on ventral surface, III, IV with basal portion unmarked but with prolateral and retrolateral sides darkened; patella IV distally darkened; tibiae III, IV ventrally darkened. Palp yellow-brown; embolar base with two right prongs, two distal prongs.

FEMALE (PBI_ OON 40898 View Materials , figs. 223–229): Total length 1.80. Abdomen slightly constricted in middle; dorsum gray with almost complete anterior transverse white stripe, followed posteriorly by two lateral white stripes, then large median white spot, posteriorly with wide, procurved, transverse white stripe; postepigastric scutum yellow-brown. Anterior genitalic ducts with transverse duct scarcely expanded at sides, most central coil extending posterior of thickened bar connecting apodemes; posterior receptaculum relatively small, occupying only central portion of space between apodemes.
