Euproctis deliana van Eecke, 1928, Zool. Meded. Leiden, 11:131.
Diagnosis. This is a somewhat variable species, and lightly marked or worn
specimens could be confused with those of layi or heavily marked dyssema.
The pale postmedial fascia of the forewing is somewhat angled at one third
from the costa rather than smoothly curved, and usually has a diagnostic dark
patch between it and the tornus. The male genitalia are distinctive, with a
triangular, apically slightly bilobed uncus, and valves with a slight projection
on the distal margin at the ventral angle. The aedeagus spines are short,
relatively robust, as is the aedeagus itself. The female genitalia resemble
those of the munda group.
Taxonomic note. A male syntype (Deli, Sumatra, slide NNM:7) is hereby designated
LECTOTYPE. A female syntype from the same locality is a female of (See
albinotata Heylaerts comb. n.).
Geographical range. Sumatra, Borneo.
Habitat preference. The species has been recorded from a wide variety of
lowland forest types, including heath, swamp and mangrove forests. A few
specimens have been taken as high as 1000m in lower montane forest.
