Diagnosis and taxonomic
note. The species is fawn with a
reddish tinge, the forewings finely and evenly mottled darker, often with a
faint discal spot. The male antennae are narrowly bipectinate. Confusion with Thumatha
species (see Thumatha Walker) is possible, but venation differences, such as the stalking
of M3 and CuA1 in the forewing, are diagnostic. Pusiola chota Swinhoe
(India) and a male attributed to "Tigrioides" phaeola Hampson (Sri
Lanka; slide 4858) have male genitalia as in sabulosalis, and are
certainly congeneric and probably conspecific, hence the localities are included
in the range below and chota is brought into synonymy. The male genitalia
have the apical part of the valves distinctly setose, and the saccular process
is angled inwards at roughly the central part of the valve. In typical Pusiola
Wallengren, a genus most diverse in Africa, the saccular process is more
evenly curved and usually reaches the apex of the valve; also there is a large
cornutus in the aedeagus vesica that is not seen in sabulosalis.
Geographical range. Indian
Subregion, Burma, Peninsular Malaysia, Sumatra, Java (van Eecke, 1930), Borneo.
Habitat preference. The
only Bornean specimen seen is the type, collected in Sarawak in the 19th
Century.
