Prodysderina piedecuesta , new species

Figures 107–117

TYPES: Male holotype, female allotype, and female paratype taken in a Winkler trap in a high Andean forest at an elevation of 2150 m at the Estacio´ n Experimental y Demostrativa El Rasgo´ n, Piedecuesta , 7 ° 03'N, 72 ° 57'W, Santander, Colombia (Sept. 21–23, 2004; I Quintero, E. Gonza´lez), deposited in IAVH ( PBI_OON 994 ) .

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

DIAGNOSIS: Males can easily be recognized by the long, distally sinuous distal prong on the embolus (figs. 110–115); females resemble those of P. otun in having the postepigastric scutum completely fused to the epigastric scutum (fig. 108), but have a semicircular, rather than oval, genital atrium (fig. 109).

MALE (PBI_OON 994, figs. 107, 110– 115): Total length 2.50. ALE separated by their radius to diameter. Sternum surface finely reticulate, microsculpture everywhere but front. Distal tip of endites forming sharp, triangular projection. Dorsal scutum not fused to epigastric scutum. Postepigastric scutum long, almost rectangular. Leg spination: femora: I p0-0-2, r1-1-1; II p0-0-2, r1-1- 0; tibiae I, II v4-4-2; metatarsi: I v2-2-2; II v3- 0-2. Embolus with distal prong sinuous, about three times as long as narrow proximal prong.

FEMALE (PBI_OON 994, figs. 108, 109, 116, 117): Total length 2.90. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, fused to epigastric scutum. Postepigastric scutum long, semicircular, extending to nearly full length of abdomen, fused to epigastric scutum. Leg spination: femora I, II p0-0-2, r1-1-1; tibiae I, II v4-4-2; metatarsi: I v2-2-2; II v3-1r- 1p. Anterior genitalic process much wider posteriorly than anteriorly.

OTHER MATERIAL EXAMINED: Colombia: Santander: Estacio´ n Experimental y Demostrativa El Rasgo´ n, Piedecuesta, 7 ° 03'N, 72 ° 57'W, Sept. 21–23, 2004, dung trap, high Andean forest, elev. 2150 m (I Quintero, E. Gonza´ lez, IAVH PBI_OON 995), 1♂, same, Winkler trap (IAVH 108133, 108140, PBI_OON 996, 997), 1♂, 1♀.

DISTRIBUTION: Northern Colombia (Santander).
