erionoma Swinhoe comb. n.
Pachyodes erionoma Swinhoe,
1893, Ann. Mag. nat. Hist. (6), 12: 219.
Terpna erionoma albicomitata Prout,
T. e. subnubigosa Prout, 1927, Gross-Schmett. Erde 12:
Terpna furvirubens Prout,
1934, Gross-Schmett. Erde 12: 140.
Diagnosis. This is a more reddish brown species than the previous two,
distinguished particularly by the whitish area just distal to the posterior
curvature of the forewing postmedial. On the underside the forewing margin is
more broadly white.
Taxonomic notes. The taxon furvirubens was established as a synonym of erionoma
by Holloway (1982), the holotype being aberrant (above). There are
minor differences between the three subspecies in the shape, apical
ornamentation and the basal spur to the costa of the valve in the male
genitalia. L. calaurops Prout (Hong Kong) has male genitalia of a similar
Geographical range. W. China (ssp. subnubigosa); N.E. Himalaya; Sundaland (ssp. albicomitata).
Habitat preference. L.
erionoma is frequent in lower montane forest, less so in upper montane
forest, with an altitude range of 1000-1790m.
