Macroglossum divergens subsp. heliophila
Distinguished from Macroglossum sitiene and Macroglossum variegatum by the white underside of the palpus and thorax, and from Macroglossum melas by the body and wings being less black. Head and thorax upperside with prominent dark mesial stripe. Tegula with a well-marked dark triangular area. Abdomen upperside with a pair of prominent black dorsal spots on 4th tergite; side tufts all white-tipped. Underside of palpus, middle of thorax, and a mesial patch on basal abdominal sternites greyish white; remainder of abdomen dull burnt-umber-brown; tail darker. Forewing upperside with the space between the 2 antemedial lines filled to form a very prominent band that is nearly straight distally and dilated basad at hind margin; 1st and 2nd discal lines curved costad anteriorly, concave between vein M1 and hind margin, the space between not completely filled, the lines remaining distinct: 1st thin, 2nd heavier, dilated behind vein M1 to reach the postdiscal line as a prominent spot, the vein here grey, bordering a well-defined postdiscal costal grey patch; A prominent subapical spot behind vein Rs4, with the space between veins Rs3 and Rs4 grey. Both wings undersides dull burnt-umber-brown, the bases shaded with yellowish buff. Forewing underside with central area darker, the discal border duller, darker brown. Hindwing upperside black border convex, more-or-less angled near vein CuA1. Hindwing underside yellow anal area well-defined, reaching about 1.5 mm. short of the tip of vein 2A.
Male genitalia: Uncus broad, rounded-truncate, flattened apically. Gnathos spatulate, upperside elevated mesially, the apical margin tapered. Valve with stridulatory scales. Harpe swollen distally, obtuse, often with a subapical, lateral, tuberculated hump. Phallus very similar to that of Macroglossum melas, but the teeth near the base of the process larger.
