Recognition. This species is characterized by pruinose clypeus; fronto-orbital setae weak to distinct; antenna mostly yellow, postpedicel darker dorsoapically; face mostly entirely pruinose extended onto anterior portion of gena ( Figs 16, 18View FIGURES 15–18); parafacial pruinose; fore coxa and all femora dark; hind femur without anteroventral preapical setae; surstylus triangular, strongly tapered to narrow apex.

Description. Frons dark to reddish-brown band above antennae; gena dark, sometimes, pale anteriorly. Face mostly pruinose extended onto anterior portion of gena; parafacial pruinose. Fronto-orbital setae weak to distinct. Antenna mostly yellow, with dorsoapical margin of postpedicel sometimes darkened; antennal bases separated by slightly more than length of pedicel. Clypeus pruinose.

Katepisternum with dense pale ventral setae, anterior to mid coxa; short setulae on anterior half. Scutum shiny with dense setulae. Coxae and femora dark, with apex of femora pale; tibiae dark with base and apex pale; tarsomeres on all legs pale with tarsomere 4 and 5 darkened dorsally; mid tibia with dark ventroapical seta, less than one-quarter length of tarsomere 1.

Male postabdomen ( Figs 51View FIGURES 51–53): epandrium rounded, evenly sclerotized, setose on posterior half. Hypandrium broad, with pair of short setae anteriorly; with rounded postgonite apically. Surstylus long, strongly tapered to narrow apex; apex arch posteromedially; setae confined mostly to posterior margin. Distiphallus tapered to narrow apex. Cercus broad, slightly shorter than dorsal length of epandrium; apex rounded.

Female postabdomen: tergite 6 ( Fig. 52View FIGURES 51–53) with bilobed anteriorly margin, broad medially with sinuous posterior margin; posterior corners slightly prolonged with pair of long setae, more than half length of tergite; spermatheca ( Fig. 53View FIGURES 51–53) short, truncate, with short pigmented denticles or papillae; without slender filaments or end apparatus of gland cells.

Distribution. This species is known from southern Arizona ( Fig. 55View FIGURES 54–55).

Etymology. The species is named after its association with Saguaro cactus and is treated as a noun in apposition.

Remarks. DNA Barcode sequence data clearly separates this new species from P. paraboydensis  sp.nov. ( Fig. 56View FIGURE 56).

Adults of this species have been aspirated from skin, around eyes and small cuts on arms and legs ( Figs 1, 2View FIGURES 1–2) ( Marshall 2012: 490), which is similar to behaviour observed in P. mexicana  .
