stat. & comb. n.
Chloroclystis oribates sayata Holloway,
Diagnosis. P. sayata is the largest Bornean species, with most specimens
having the forewing relatively uniform dark brown, with the postmedial and
antemedial fasciae only slightly edged paler, the former whitened on the
interior element only opposite the disc. The hindwings are darker grey than in
other species with only the postmedial fascia emphasised to any degree.
Distinction from coelica is discussed under that species.
Taxonomic notes. See P. coelica notes above. The two Bornean species appear to be
more closely related to each other than to the Javan P. oribates Prout
comb. n. both with regard to curvature of the valve costa (straight in oribates)
and the cornuti of the aedeagus vesica (oribates has one large
cornutus and a series of smaller ones), hence they are probably best both
treated as distinct species.
Geographical range. Borneo.
Habitat preference. This is one of four species characteristic of the
Kinabalu summit zone (Holloway, 1970). Most records are from 2970m to 3750m,
though one specimen was taken at 2600m. The main habitat consists of subsummit
dwarf forest amid areas of exposed granodiorite rock.
