HABITAT. — As with most species of the genus, Orphulella chumpi n. sp. is found in grassy areas in the valley of “Callejón de Huaylas”.
DIAGNOSIS. — Similar to Orphulella fluvialis , from which it differs mainly in the following features: hind femora with stridulatory pegs (without stridulatory pegs in O. fluvialis ), lateral carinae of pronotal disk distinct in central part (usually indistinct in O. fluvialis ) and cut by one sulcus (cut by two or three sulci in O. fluvialis ); posterior margin of pronotum slightly angulate (rounded in O. fluvialis ).
DESCRIPTION
Males
Body colour light brown on top, brown-gray on sides and brown ventrally. Hind femora with few dark markings on the outer faces.Hind knees dark brown. Hind tibia brown. Lateral foveolae of the fastigium barely visible from above.Antennae short and slightly ensiform, light brown proximally and dark brown distally.Pronotum with a black band on lateral lobes, just beneath the lateral carinae ( Fig. 8A). Posterior margin of pronotal disk angulate, slightly rounded. Mid-longitudinal carina on pronotum prominent and cream colour; lateral carinae distinct throughout their length, nearly parallel on the prozona, constricted in center, diverging on the metazona and cut by one transverse sulcus( Fig.8C). Hind femora in males with stridulatory pegs.Wing length barely reaching the end of the abdomen ( Fig.8A).Like other gomphocerines, species in the genus Orphulella do not show diagnostic characters in the phallic complex ( Fig. 8E, F).
A
Measurements (in mm): body length to end of hind femur: 11; hind femur length: 6.8.
Females ( Fig. 8B, D)

REMARKS
A modified key to the South American species of Orphulella based on Otte’s key (1979) including the new species O. chumpi was added to OSF.
