Eudocima anguina (Schaus, 1911)

( Figs 7 : A–B, 23: H)

Schaus (1911b) raised the possibility that this species was conspecific with E. collusoria , but these two species differ in wing shape, pattern, and COI 5’ characters. This is one of the three smallest Neotropical Eudocima species (32 mm, n=2), along with E. memorans (33 mm, n=1) and E. collusoria (34–35 mm, n=2). Of the three only E anguina has a fairly straight rather than strongly concave apical line. The forewing of E. anguina has a more pointed apex and tornal hook, and more angular outer margin relative to the other two species. Also, only E. anguina lacks dark hairs and scales in the dorsal hindwing basal area. The hindwing medial patch may be absent ( Fig. 23 : H). When present the patch does not extend anterior of vein Cu1, whereas in the other two species it extends to vein M2 or beyond. The female dorsal forewing has a white spot on the basal side of the PM line between veins Cu2 and Cu1, lacking in the other two species. This species is rarely recorded from Columbia (Vargas-Fonseca et al. 2020) north to Costa Rica.
