Xylophanes pistacina
Basal ciliae of antennal segments distinctly prolonged. Outer spur of midtibia somewhat shorter than inner spur. Upperside of abdomen without lines. Forewing upperside ground colour greenish-buff, but variable, some individuals much greener. Subbasal and antemedial lines vestigial, the two distal ones forming a band at the apex of discal cell, angled at CuA1; the two proximal postmedial lines more or less merged to form a band, the inner often straight; the third postmedial line very faint; the fourth more distinct and emphasized by vein dots; postmedial lines 2 to 4 dentate; postmedial line 5 curved from the wing apex and continuous with a greenish olive patch from M2 to M3. Brown border broad, less angulate posterior to M2 than in Xylophanes schausi. Pale band highly suffused with olive-brown.
Male genitalia: Uncus truncate-sinuate. Gnathos rounded distally. Harpe long, very slender, pointed and somewhat sinuate, as in Xylophanes schausi. Phallus with right process short and pointed; left process also short, dentate and less projecting than in Xylophanes schausi.
