Material examined.

Holotype. UNITED STATES • ♀, CNC; Arizona, Sierra Vista, Huachua Mountains, Ramsey Canyon ; 1829 m.a.sl.; 07 Nov 1967; Sternitzky leg; CNCHYM 01988.

Diagnosis.

This species is morphologically similar to P. gainesvillensis (Florida), P. jaymeae (Canada), and P. liagrantae (Costa Rica), but there are enough morphological differences (see key above for details on how to separate those four species) and disparate geographical distributions (including different ecosystems and considerable variation in altitude) to consider all of them as different.

Description.

Head: mostly black, labrum and mandibles yellow. Flagellomeres: dark brown. Mesosoma: black. Tegula: yellow. Metasoma (dorsally): mostly dark brown to black, T3 with yellow spots laterally. Metacoxa: yellow. Malar distance: 0.3 × eye length. Fore wing areolet: present. T1 sculpture: anterior 0.5 smooth, posterior 0.5 sculptured. T2 sculpture: mostly smooth but with sculpture near margins. Body length: 3.70 mm. Fore wing length: 3.80 mm. Ovipositor length: 2.40 mm. Ocular-ocellar line: 0.17 mm. Interocellar distance: 0.10 mm.

T2 length/width at posterior margin: 0.12 mm/ 0.53 mm.

Distribution.

UNITED STATES, Arizona, Huachuca Mountains, 1,829 m.a.s.l.

Biology.

Unknown.

Molecular data.

Not available.

Etymology.

Named after the Huachuca Mountains, one of the major Madrean sky island ranges in Arizona. The Madrean sky islands are pine-oak woodlands found at higher elevations in Mexico, Arizona and New Mexico (USA); they are surrounded at lower elevations by the Sonoran and Chihuahuan deserts, and are important because of their endemism, and relict populations.
