Stenoloba elegans Prout (Plate 2, Figs 127, 128) Stenoloba elegans Prout, 1928, Sarawak Mus. J., 3: 462. Diagnosis. This and the next species, robusta Prout, have a similar forewing facies of black markings and brownish‑green shading on pale grey. The antemedial is oblique, the postmedial sinuous, most strongly curved round the discal area, where the reniform is in the form of a figure ‘8’ with the upper lobe larger. There is an oblique black dash between the anterior part of the curve of the postmedial and the costa just subapically. In robusta all these black markings are more clearly defined, and the reniform is larger and more prominent. Taxonomic note. This and the next species are very similar to S. futii Kononenko & Ronkay (Peninsular Malaysia; illustrated as robusta Prout by Barlow (1982)). The genitalia of all three are similar; futii often lacks a darker grey shade in the pale grey margin of the forewing. A single male from Java belonging to this group has a more distinctly double and narrow forewing antemedial; the male genitalia (slide 20964) have a blister-like bump centrally on the interior margin of the valve sacculus. Geographical range. Borneo. Habitat preference. This species is rare but occurs over a much greater range of altitude and habitat than the next, being recorded most recently from coastal forest and secondary growth at Seria, 300m in primary forest of the Ulu Temburong and 1618m and 1670m in montane forest on Bukit Retak and Bukit Pagon respectively in Brunei. It has also been taken at about 1500m near Kundasang on the southern slopes of G. Kinabalu. One specimen was taken in a canopy sample from primary forest at 170m near the Danum Valley Field Centre, Sabah (S.J. Willott, unpublished data). The type material is from about 1300‑1600m on Mt. Poi in Sarawak, and there is a further specimen from moss forest at about 1250m on G. Dulit |
