Enpinanga vigens
Habitus: Male: Forewing somewhat scalloped posteriorly (as in Enpinanga assamensis and unlike Enpinanga borneensis). Hindwing more distinctly dentate than in Enpinanga borneensis. Upperside of head and thorax with a broad, brown, lateral stripe, lighter than in Enpinanga assamensis or Enpinanga borneensis so much less prominent. Very similar to Enpinanga assamensis but grey ground colour overlain with greenish scales when fresh (fade to brown with age); antemedial lines more conspicuous; outer margin of dark brown rectangular patch distad of discal spot diffuse. Hindwing upperside inner margin narrow, only slightly lighter than rest of wing, not prominent as in Enpinanga borneensis. Female: Forewing upperside similar to Enpinanga assamensis but ground colour darker grey-brown (as in Enpinanga borneensis) and dark brown median line half as broad. Hindwing upperside more uniform in colour than Enpinanga assamensis, without a darker marginal area; inner margin paler than rest of the wing, but not as bright or prominent as in Enpinanga borneensis.
Male genitalia: Uncus slightly longer than gnathos, slightly spatulate, weakly curved. Gnathos shallowly sinuate distally. Valve with a patch of stridulatory scales. Harpe produced into a slender, acute, curved process.. Phallus process spatulate, four times as long as wide, narrower basally, rounded apically, bearing teeth along the margin.
Other than the lectotype, and despite intensive collecting since 1980, no further specimen of Enpinanga vigens has been found in the Philippines, casting doubt on the veracity of the type locality. It is not mapped here.
