Etymology. The specific name refers to the Caliente Range.

Diagnosis. This is a smaller and less robust species of Protoperigea and superficially resembles P. subterminata . It has a slender thorax and abdomen (a, Fig. 12 View FIGURES 1 – 21 ) with the forewing ground color pale grayish cream and a dark reniform spot (b, Fig. 12 View FIGURES 1 – 21 ). The postmedial line is double and the area between the postmedial and the subterminal lines is dark (c, Fig. 12 View FIGURES 1 – 21 ). The species can also be distinguished from P. subterminata by the pale fuscous hindwing (d, Fig. 12 View FIGURES 1 – 21 ); the hindwing is white in P. subterminata .

Description. Antenna finely ciliate in males, filiform in females; palpus covered laterally with thin dark brown scales, apex pale; head, collar and thorax covered with uniformly pale gray cream colored hairlike scales, venter covered with hairlike scales concolorous with dorsum; abdomen covered with pale gray cream colored scales, venter concolorous with dorsum; forewing ground color pale gray cream colored; basal and median areas lightly dusted with dark scales; claviform spot absent; orbicular spot a small dark dot, reniform spot small, kidney­shaped, filled with brown gray; antemedial line dark brown, weak, two dark patches on costa; median line absent medially, dark patch on costa; postmedial line double, dark, inner line thin, serrated, outer line smooth, enclosed area pale, dark dot on costa; subterminal line serrate, dark, heavily dark­shaded inward; subterminal area dark; terminal line consisting of black spots; fringe concolorous with ground color with a dark basal line; ventral side uniformly very pale gray cream colored, darker towards apex. Hindwing whitish, broad gray subterminal shade; fringe whitish with brown basal line; ventral side as in dorsal side, but with small discal spot. Male genitalia ( Figs. 40 View FIGURES 40 – 63 a and 40b): Juxta round; valve length 2.75–2.8 mm, width at middle 0.9–1.0 mm, broad and rectangular; cucullus a dorsal fingerlike projection, width 0.15 mm, slightly curved ventrally; clasper length 0.7 mm, slender, S­shaped; aedeagus length 2.5 mm, width 0.8 mm, slender and curved; everted vesica length 3.4 mm, width 1.4 mm, ovate, tapering distally, with patches of small spines. Female genitalia ( Fig. 74 View FIGURES 63 – 79 ): Ovipositor lobes triangular, 0.3 mm wide, covered in small setae; posterior apophyses 1.9 mm long, anterior apophyses 0.9 mm long; ductus bursae short and very broad, length 1.8 mm, width 1.4–1.5 mm, no abrupt narrowing (unlike in P. umbricata and subterminalis), sclerotized, smooth, with lateral barlike thickenings; corpus bursae spherical, 2.4 x 2.15 mm, surface smooth with faint wrinkles.

Distribution and habitat. The few known specimens of P. calientensis are from desert canyons around the edges of the Colorado and Mojave Deserts from the Mexican border north to Lake Tahoe. The flight period is late October–November.
