“Tipasa”
ferripunctum
Walker
comb. n.
Plusia
ferripunctum Walker,
[1863] 1864, J.
Linn. Soc. (Zool), 7: 69.
Diagnosis.
The disparity in area between the forewings and hindwings, together with the
reticulated pale golden patches on the dull brownish grey of the former, render
this species unmistakable.
Taxonomic
note. The species is here loosely associated with Tipasa
species
such as eubapta
on
grounds of the general resemblance of forewing facies and male genitalia,
particularly the structure of the valve, the apical portion of which in ferripunctum
has
a general appearance consistent with membership of the Saroba group
of genera. The labial palps are longer and more strongly upcurved than in eubapta.
The male retinaculum is similarly broad. However, these species do not show a
particularly close affinity with the generic type species as discussed above.
Geographical
range. Borneo.
Habitat
preference. All recent records are from 300m or below, and all from lowland
forest at Labi and Ulu Temburong in Brunei, from near the Danum Valley Field
Centre in Sabah, and from the Barito Ulu of Kalimantan Tengah. The original
specimens, collected by A.R. Wallace in Sarawak, were probably also from the
lowlands.
