Bidysderina perdido , new species

Figures 590–630

TYPE: Male holotype taken by canopy fogging at an elevation of 2085 m on the Río Perdido trail in the Estacio´ n Biolo´ gica Yanayacu , 0 ° 36.496'S, 77 ° 52.947'W, Napo, Ecuador (Nov. 26, 2009; Niarchos Exped.), deposited in QCAZ ( PBI_OON 30627 ) .

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

DIAGNOSIS: Males can be recognized by the long, distally darkened embolus and the long, distally narrowed conductor (figs. 626– 628), females resemble those of B. wagra in having a relatively small atrium, but the stem of the anterior genitalic process is shorter and wider (fig. 630).

MALE (PBI_OON 30627, figs. 590– 620, 623–628): Total length 1.72. ALE separated by less than their radius. Leg spination: femora: I p0-0-2, r0-1-0; II p0-0- 1; tibiae: I v4-4-1p; II v4-4-0; metatarsi: I v2- 1p-2; II v2-0-2. Embolus long, sharply bent at 2/3 its length, conductor long, distal portion extremely narrow, threadlike.

FEMALE (PBI_OON 30615, figs. 621, 622, 629, 630): Total length 2.40. Dorsal scutum covering 1/2 to 3/4 of abdomen length. Leg spination: femora: I p0-0-2, r0- 1-1; II p0-0-2, r0-1-0; tibiae: I v4-4-2; II v4-4- 1p; metatarsi: I v2-1p-2; II v3-0-1. Genital atrium short, wide, anterior margin straight except at middle, where procurved, posterior margin procurved.
