Palpal Description: “Palpi dusky on dorsal and lateral surfaces of all segments except coxae. . . . There are 15-20 slender papillae in slender palpal scopula, and 6-8 long, spine-like setae ventrally on palpal femora, 3 pairs on tibiae, and 4 or 5 almost not recognizable, on metatarsi. Metatarsus of palpus 3.5 times the length of tarsus” (Muma, 1989, p. 31).
