Material examined.

Holotype. UNITED STATES • ♀, CNC; Arizona, Patagonia Mountains ; 1676 m.a.sl.; 10 Jul 1962; H.E. Milliron leg; CNCHYM 01986.

Diagnosis.

This species is morphologically similar to P. tracyvindasae (Costa Rica), but can be distinguished from it (and from all other described species of Promicrogaster from North and Meso America) because of its clypeus with a strong notch centrally on posterior margin.

Description.

Head: mostly dark reddish-brown, labrum and mandibles yellow, clypeus orange-yellow. Flagellomeres: dark brown. Mesosoma: mostly black but ventro-laterally reddish-brown. Tegula: yellow. Metasoma (dorsally): mostly dark brown to black. Metacoxa: yellow. Malar distance: 0.3 × eye length. Fore wing areolet: present. T1 sculpture: mostly smooth. T2 sculpture: mostly smooth but with sculpture near margins. Body length: 4.90 mm. Fore wing length: 4.90 mm. Ovipositor length: approximately 2.90 mm. Ocular-ocellar line: 0.20 mm. Interocellar distance: 0.12 mm. Posterior ocellus diameter: 0.10 mm. Metacoxa length: 1.10 mm. Metafemur length: 1.20 mm. Metatibia length: 1.50. T1 length/width at posterior margin: 0.65/ 0.40 mm. T2 length/width at posterior margin: 0.21 mm/ 0.80 mm.

Distribution.

UNITED STATES, Arizona, Patagonia Mountains, 1,676 m.a.s.l.

Biology.

Unknown.

Molecular data.

The holotype rendered a partial DNA barcode (164 base pairs), the sequence page in BOLD is HYCNE1802-11.

Etymology.

Named after the 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.
