Diagnosis. Distinguished from the remaining species of Pediella by male cerci slender; tegmina with acute apex; and phallic complex with cingulum largely developed with elevated collar like zygoma, rami wide, extended ventrally mandible like shaped; apical valves of aedeagus ventrally concave.

Description. Body color dorsally olive green with tinges of brown, with a yellow mid-longitudinal stripe on dorsum of abdomen and epiproct; face, anterior edge of pronotum and thorax ventrally whitish green porcelaine; epimeron with a whitish porcelain stripe; abdominal sternites and subgenital plate brightly red; ventral area of first and second pair of legs red; hind femur with ventral and inner area orange red, dorsal area olive green, outer area red with tinges of yellow; hind tibia and tarsi orange red. Tegmina with acute apex

( Fig. 1B ). Cerci slim, tapering at the distal end, apex acute ( Figs. 4B, F ). Phallic complex ( Figs. 5F–J ): cingulum largely developed with elevated collar like zygoma; rami wide, extended ventrally mandible like shaped; arch of the cingulum large; apical valves of aedeagus ventrally concave; epiphallus with largely developed lophi.

Females: body color brown, with patches of cream areas; whitish mid-longitudinal stripe on dorsum of abdomen; face cream; abdomen ventrally yellow; hind femur ventral and inner area red.

Measurements. Body length 18.4 mm (17–19) males, 22.6 mm (21–23) females; femur III length 10.2 mm (10–11) males, 12.6 mm (12–14) females.

Distribution. Perú, Ancash ( Fig. 6 ), in puna grassland areas with bunchgrasses of Festuca and Poa forming tussocks. Spaces around the tussocks filled by numerous herbs, including non-tussock-forming grasses and sedges, prostrate or low-growing forbs. (See geographic distribution 1).
