ETYMOLOGY: The specific name refers to the male palpal bulb, which resembles that of
P. armata
but is much larger.
DIAGNOSIS: Males resemble those of
P. armata
but have a much larger palpal bulb (figs. 77–79); females have a distinctively enlarged, rounded, sclerotized anterior portion of the posterior receptaculum (figs. 83, 84).
MALE (PBI_OON 20, figs. 1–30, 74, 77– 82): Total length 1.83. ALE separated by less than their radius. Sternum surface coarsely reticulate, microsculpture everywhere but front. Anterior portion of endites sharply pointed. Dorsal scutum not fused to epigastric scutum. Postepigastric scutum almost semicircular. Leg spination: femora: I p0-0-2, r1-1-1; II p0-0-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-1p; II v3-2-0. Embolus with distal prong about four times as long as proximal prong, sharply bent at about 1/4 its length.
FEMALE (PBI_OON 38040, figs. 31– 60, 75, 76, 83, 84): Total length 2.13. Sternum with additional tuberculate setal bases near anterior groove. Dorsal scutum covering 1/2 to 3/4 of abdomen length, more than 1/2 to most of abdomen width, fused to epigastric scutum. Postepigastric scutum widely hexagonal, covering about 1/3 of abdomen length. Leg spination: femora I, II p0-0-2, r1-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-2; II v3-2-0. Posterior margin of genital atrium with rounded posterior extension representing sclerotized portion of posterior receptaculum.
