Eumorpha orientis ( Daniel, 1949)

Pholus obliquus orientis Daniel, 1949

Eumorpha obliquus orientis ( Daniel, 1949)

Type locality: Brazil

( Figs 10a–b , 11e–h )

Characterization. Wingspan is 13.25 cm, the length of the forewing is 6.04 cm and the hindwing is 3.43 cm.

Head: grayish, median dark band, brown palpi with the white distal region.

Thorax: grayish, tegulae in dark brown triangular shape, dark brown median band.

Forewing: dorsal view - striated, discal bar shaded at the top, leaves the base of the wing and extends to the middle of the wing; discal band modified in two wavy dark brown discal stripes coming from the outer margin close to the discal spot, “Y” spot without bifurcation, leaving the costal margin diagonally to the outer margin separating the darker apical margin; presence of two dark spots in the post-discal area and close to the “Y” spot; semi-lunar subapical patch with a dark brown color; triangular spot on the inner margin without contour, submarginal band almost imperceptible, ventral view: predominantly dark brown, dark, non-uniform spot, ranging from the apex to the end of the outer margin against the inner margin, having a triangular projection towards submarginal area in the middle of the outer margin, followed by smaller undulations, it has two striations that go from the inner margin to the costal margin, one discal striation and the other dividing the post-discal area of the submarginal area.

Hindwing: dorsal view—discal spot extends to the apical area, outer margin with the lighter region having two dark spots, ventral view: predominantly brown, with a greenish spot that runs from the base, passing through the inner margin ending at the anal angle, two striations going from the inner margin to the costal margin, one of them is smooth separating the discal from the post-discal area and the other is serrated, separating the post-discal area from the submarginal area.

Abdomen: dorsally, with grayish scales, pair of median spots in segment I-VII, a median spot in segment VIII, ventrally, with brown scales.

Male Genitalia: Uncus single sickle-shaped. Valva, uniform width, inner margin almost straight with rounded apex. The sacculus, shorter than half the size of the valva, with a triangular shape, is more robust than in E. obliquus . The saccular process does not have a serration at the base of the spine. Sac symmetrical with anterior projection, forming a light tip at the apex. The aedeagus, smaller than the valva size, cylindrical and uniform in shape, with an elongated projection at the apex.

Diagnosis.

Habitus. similar to E. obliquus . It differs only through the genitalia, slightly curved valva ( Fig 11f ), sacculus narrowing at the apex making a slight curvature at the end of the saccular process, sacculus less than half the length of the valva, and the saccular process with a smooth inner margin ( Fig 11g ).
