Lophoptera
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.
Holotype . SABAH: Mt.
Kinabalu, 'Power
Station' 1930m, vii-ix 1965, Cambridge Expedition to Mt. Kinabalu 1965 (H.J.
Banks, H.S. Barlow & J.D. Holloway) BM noctuid slide 11317.
Paratypes. 3 specimens from G. Kinabalu as listed by Holloway (1976), BM noctuid
slide 9320 (); l SARAWAK, Gunong Mulu National Park (Holloway) Site 14

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
attributable. It is larger than brunnama, of similar colour and facies,
but virtually lacking the apical yellow mark of the forewing and having the base
of the hindwing only slightly hyaline.
Geographical range. ?Sri Lanka, Borneo, Sumatra, Sulawesi, Ceram.
Habitat preference. All Bornean specimens have been taken in forested
localities between 1000m and 2000m.
