Eublemma roseonivea Walker

Acontia roseonivea Walker, [1863] 1864, J. Proc. Linn. Soc. (Zool.), 7: 49.

Porphyrinia roseonivea ab. curvilinea Warren, 1913, Gross-Schmett. Erde, 11: 224.

Diagnosis

This species, along with roseonivoides, barlowi and carneola, have the wings more broadly pinkish grey, darkening up to a white submarginal fascia. This darkening on the hindwing is usually stronger but more restricted to the area adjacent to the fascia. The pink area may also become abruptly paler at an angled medial on the forewing, though this appears just as a slightly darker pink fascia on a generally pale background in roseonivea. In roseonivea the forewing submarginal is dentate only in the anterior third of the wing, though there may be a slight interior tooth at one third from the dorsum; that of the hindwing is evenly curved, and the area immdiately basal to it is particularly intensely brown (less so in roseonivoides and barlowi).

Taxonomic note

The holotype (OUMNH: 1349) resembles ab. curvilinea Warren, based on ab. 1 of Hampson (1910), rather than material (the Sarawak: Malang specimen of the next species) that Hampson considered typical.

Geographical range

Borneo, Peninsular Malaysia (Penang).

Habitat preference

The holotype was collected in Sarawak, probably in the lowlands, by A.R. Wallace, and that of curvilinea is from Sandakan on the coast of Sabah. A third specimen has been taken in lowland dipterocarp forest at 300m in the Ulu Temburong of Brunei. A fourth was taken in the canopy (tree-tower) of lowland dipterocarp forest at 170m near the Danum Valley Field Centre in Sabah.

Biology

Robinson et al. recorded the larva of this species as feeding on Theobroma (Sterculiaceae) and Kerria (Coccoidea), but these records could equally relate to roseonivoides and barlowi.
