Bertula proctori sp. n.

Bertula proctori
Figure 85

13-15mm. This species is much larger than the previous one, the male antennae much more weakly fasciculate, almost ciliate; the labial palps, though similarly recurved, have the third segment only slightly smaller than the second. The fasciation of the forewing is more curved, less oblique, and the reniform is obscure, with no white in evidence. There is more of a distinct pale submarginal. The hindwing is only weakly fasciated, with just a weak but entire fascia at two thirds; on the underside the discal lunule is accompanied by a more basal ovate spot (weak or absent in bornedescripta). The male genitalia have the valves much more tongue-like, apically rounded. The aedeagus vesica is asymmetrical, slightly lobed, and with general but rather sparse scobination.

Holotype . SARAWAK: Gunong Mulu Nat. Park, R.G.S. Exped. 1977-8 (J.D. Holloway et al.), Site 20, Mar.-April, W. Melinau Gorge, 150m. 422577, FEG 3, kerangas. BM noctuid slide 19642.

Paratypes: 4 as holotype; 1 as holotype but Site 21, March, W. Melinau Gorge, 130m, 423576. alluvial / kerangas bank.

Etymological note. The species is named in memory of John Proctor in recognition of his pioneering work in nutrient recycling in tropical forests. He led the Forest Ecology Group on the Mulu Expedition, establishing a series of plots for detailed studies. The type locality of this species is his kerangas plot, FEG 3, and it is possible that the larvae contribute to nutrient recycling there.

Geographical range. Borneo.

Habitat preference. See the previous species.
