Tampea nodosa sp.
n.
 ,
 9-10mm.
Both sexes of this species are similar to females of metaphaeola Hampson, with yellow forewings and grey hindwings, the
latter with the costal and distal margins narrowly yellower. On the underside
the male forewing has the central part with a diffusely bordered grey patch, and
the hindwing is more extensively yellow than above, the grey most intense at the
tornus, up the dorsum, and in a border that fades away towards the apex. The
grey is more extensive on the female underside. The male antennae have a
distinct irregular swelling at the base of the flagellum as in T.
hammatocera Wileman & West comb. n. (Luzon) and an
undescribed species from Bali (slide 5433). The male abdomen has coremata
associated with the seventh and eighth segments but with two on each side and a
much more complex structure than in reversa.
The uncus is deep centrally but lacks an apical spur; it has lateral
swellings at the base. The valves taper slightly but have an irregular costa
with a semicircular basal projection and spurs at two-thirds and subapically as
illustrated. The vinculum is as in reversa
but without an ornamented membrane, and the aedeagus is also similar but
with a longer, more convolute vesica. In hammatocera
the basal semicircular process of the costa is lacking, and the two more
distal spurs are closer together on a more protruded section of the costa; the
base of the uncus is less swollen. The male from Bali is more similar to nodosa
but the semicircular process is shallower, and there is only one spur more
distally. The abdominal coremata in both these species are similar to those of nodosa,
as is the aedeagus and its vesica. The female genitalia are similar to those
of metaphaeola and accepta,
having a corethrogyne as in the former, but the bursa is more elongate, more
generally scobinate, and has a more basal, irregular plate of scobination in
addition to the signa. One of the females listed below is that attributed to metaphaeola
by Hampson (1900).
Holotype
. SARAWAK: Gunong Mulu Nat. Park, R.G.S. Exped. 1977-8 (J.D. Holloway
et al.), Site 18, W. Melinau Gorge, 100m. 428563, alluvial forest and
riverside veg., BM arctiid slide 2684.
Paratypes:
2 general
data as above but Site 14, February, Camp 2.5, Mulu, 1000m. 413461; 1 (slide
5436), 1 (slide 5242) as previous but Site 15;
1 (slide 5235) BORNEO: Sarawak (A.R.
Wallace).
Geographical
range. Borneo.
Habitat
preference. Four
specimens are from lower montane forest but the holotype is from a river bank
with alluvial forest. The Wallace specimen is also likely to have been taken in
the lowlands.
