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.
