brunnama sp. n.
Gyrtona nama Swinhoe; sensu Holloway, 1976: 20.
14mm. The forewings are deeper than in nama, dark brown rather
than purplish grey; the angled apical yellow mark is less acute; the postmedial
is more definite, more obtusely angled, with a zone of paler ground basad, a
more extensive row of black flecks within it, and a central row of transverse
yellow dashes with black flecks distad just distal to it. The male genitalia are
very similar to those of nama but the valve apex is rounded, symmetrical.

Taxonomic note. One further species of the nama group, hayesi Sugi, occurs
in Japan, with a specimen from the N.E. Himalaya in the BMNH possibly also

but virtually lacking the apical yellow mark of the forewing and having the base
of the hindwing only slightly hyaline.

localities between 1000m and 2000m.
