Narosa
velutina Walker sp. rev.
Narosa velutina Walker, 1862, J. Linn. Soc. Lond. (Zool.) 6:
171.
Narosa velutina Walker; Hering, 1931: 675, as synonym of conspersa Walker.
Diagnosis. The species is smaller than concinna (11-12mm). The forewings are
squarer, less produced apically, with the darker orange zone subbasally and the
postmedial bar less definitely divided by a paler fascia or zone. The main
difference from concinna is in the male genitalia where the gnathus is
less deeply bifid, the juxta and associated structures smaller, less heavily
spiralled and apically more finely spined.
The genitalia of two
specimens are illustrated to show the variations.
Geographical
range. Borneo,
Peninsular Malaysia.
Habitat preference. The species is known mainly from lowland localities
in rainforest, the highest record being from Kiau at 1000m on G. Kinabalu.
