Bidysderina bifida , new species

Figures 631–641

TYPE: Male holotype taken from leaf litter at an elevation of 2140 m on the trail to the San Jorge de Yanayacu Wildlife Reserve , 0.58813 ° S, 77.88428 ° W, Napo, Ecuador (Nov. 25–30, 2009; M. Ramírez et al., Niarchos Exped.), deposited in QCAZ ( PBI_OON 30611 ) .

ETYMOLOGY: The specific name refers to the bifid palpal conductor.

DIAGNOSIS: Males can easily be recognized by the greatly elongated embolus and bifid conductor (figs. 637, 639), females by the short, wide tip of the anterior genitalic process (fig. 641).

MALE (PBI_OON 30611, figs. 631, 634– 639): Total length 1.80. ALE separated by less than their radius. Leg spination: femora: I p0-0-2, r0-1-0; II p0-0-1; tibiae I, II v4-4-1p; metatarsi: I v2-1p-2; II v2-0-2. Embolus very long, sinuous, conductor bifid, with proximal prong situated almost directly ventrally of distal prong.

FEMALE (PBI_OON 49529, figs. 632, 633, 640, 641): Total length 2.51. 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, II v4-4-2; metatarsi: I v2-1p-2; II v3-0-2. Genital atrium short, wide, anterior margin sinuous, closely approximating posterior margin of epigastric scutum, posterior margin procurved.
