Holocraspedon vaneeckei sp. n.  
Philenora sordidior Rothschild sensu van Eecke, 1926, Zool. Meded Leiden, 9:277.

Holocraspedon vaneeckei
(paratype) (x 1.56)

, 7mm. The general coloration and marking is similar to that of bilineata, but with the forewing postmedial more oblique, the antemedial faint but strongly curved and the dark markings in the marginal zone fused into a broad band distal to it that tapers away near the dorsum; the oblique line into the dorsal angle is usually obscure, incorporated into some irregular submarginal marking. In sordidior Rothschild there are strong transverse antemedial and postmedial fasciae on a paler ground colour, and the marginal marking is a V-shape with its angle at the centre of the postmedial; the facies of parallelum is similar to that of sordidior. The male genitalia are similar to those of sordidior, but the aedeagus vesica has a cluster of four cornuti, one about twice as long as the rest, and one even longer, slender, sinuous one on a narrow diverticulum; in sordidior Rothschild there are just two together, the size of the largest of the four in vaneeckei. The female genitalia have very long apodemes and a prominent appendix bursae, with spining throughout the corpus and into the base of the appendix.
