Parolulis olivescoides sp. n.
, 11-12mm. The species resembles P. olivescens Hampson (Sri Lanka, S. India) closely in facies, the ground of the wings being a pale straw yellow, shaded and marbled with slightly greenish brown. The forewing fasciae are pale as in the ground colour, the postmedial acutely angled and the antemedial curved, oblique. The reniform is slightly darker-centred than the rest of the wing shading. The male genitalia have the long blade-like process on the valve typical of the genus, but the other process is less rigid, narrowly triangular, finely setose. Only females of olivescens were available in BMNH, having a long, ribbon-like ductus bursae and two small, oblique scobinate signa in the corpus bursae as in the type species. The latter are present but more irregular in olivescoides, but the ductus is considerably shorter.

Paratypes: 2 as holotype; 1 BRUNEI: 3m, Seria, secondary and coastal veg., 3.6.1979 (Lt. Col. M.G. Allen); 1 (slide 19234) BRUNEI: U. Temburong, 1° forest, 300m, iv.1981 (I. Gauld); 1 SARAWAK: Gunong Mulu Nat. Park, R.G.S. Exped. 1977-8 (J.D.Holloway et al.), Site 16, March, Long Pala (Base), 70m, 324450, alluv./second. for.; 1 BORNEO: Kuching, Nov. 1902; 1 SAR [Sarawak, A.R. Wallace],

Taxonomic note. Another member of the olivescens complex is P. ayumiae Sugi comb. n. (Japan), where the male genitalia are more as in renalis, with the apical part of the valve considerably reduced (plate 378: 3 in Inoue et al. (1982)). Further, undescribed species occur in Sulawesi and Seram.

Geographical range. Borneo.

Habitat preference. This is a lowland species, not recorded above 300m. It has been taken in hill and alluvial dipterocarp forest, in dry heath forest and in coastal associations. S.J. Willott (unpublished data) recorded it somewhat more frequently in canopy samples than in understorey ones in lowland forest near the Danum Valley Field Centre. Chey (1994) recorded it as frequent in lowland softwood plantations in Sabah.
