Hemaris galunae
Male: Very similar to Hemaris tityus and Hemaris radians but with a broader marginal band on both forewing and hindwing. Extent of the light yellow scaling on the black scaling of the basal field and inner edge angle of hindwing upperside and underside intermediate between that of Hemaris tityus and Hemaris radians. Antennae shorter and in the apical third somewhat broader than in Hemaris tityus, coming nearer to the condition in Hemaris radians. Abdominal tufts almost black with few light brown or light yellow hair-like scales, which are more strongly interspersed in Hemaris tityus and Hemaris radians.
Female: Rather larger than the male, with longer and slimmer antennae.
Male genitalia: Depth of right-angled groove of right valve intermediate between those of Hemaris tityus and Hemaris radians. Harpe of right valve broad and flatly pushed forward, so that the outer edge of the upper third is rather nicked and beset with long spines. In Hemaris tityus and Hemaris radians, it is smaller, flat and not pushed forward. Harpe shorter than in Hemaris tityus and Hemaris radians and not inflated in the first third. Phallus somewhat longer that the overall length of the genitalia. Vesica smooth and without cornuti.
Female genitalia: Antrum bell-shaped.
