Xylophanes belti
Rothschild & Jordan (1903) referred to Xylophanes belti as "One of the finest species"; certainly cannot be confused with any other species of Xylophanes. Uppersides of forewings, head, thorax and abdomen deep olive green; a stripe from the forewing base to palp, a lateral patch on the abdomen basally and the undersides of the body and wings deep carmine-red. Abdomen with traces of 2 rows of dorsal dots ventrally. Outer spur of midtibia little shorter than inner. Forewing upperside deep olive green, interspaces with a silky blue-grey gloss; three antemedial lines, second and third merged together; postmedial lines indistinct, third and fourth separated by a conspicuous, straight, silky blue-grey line. Medial band pale olive green, fading to greenish-buff.
Male genitalia: Harpe curved sharply upward at apex, compressed, the acute upper edge notched and dentate. Phallus similar to that of Xylophanes anubus but the dentate right process broader, the dentate patch on the left not so prominent and the proximal teeth arranged more regularly in a row.
