Diagnosis:
Forewing length:
♂
17–18 mm
. Along with
Anoba rigida
,
A. pectinata
and
A. polyspila
have typical mosaics of archipelagic dark greenish-brown patches on pale brown forewings which readily separate these three species from the other congeners. Externally,
A. rigida
differs from
A. pectinata
by the presence of fasciculate antennae in male (narrowly bipectinate in
A. pectinata
), forewing with the basal dark patch more broken, and the medial patch well separated from the submarginal and apical patches (more or less contiguous in
A. pectinata
) and paler hindwing. In male genitalia
A. rigida
is conspicuously distinct from
A. pectinata
by the upwardly curved rectangular valva with a thumb like distal costal process on well sclerotized costa, shorter and stouter aedeagus, and vesica with several diverticula and a cluster of many strong cornuti distally. In comparison to other two species,
A. polyspila
is darker, with slightly smaller dark green patches on forewing, and the medial patch, in particular, does not touch the inner margin completely (which is well extended up to the inner margin in
A. rigida
and
A. pectinata
). Moreover, the hindwing in
A. polyspila
is darker towards the outer margin.
Distribution:
Indonesia
(
Java
,
Riau
,
Sumatra
),
Malaysia
(Malay Peninsula, Borneo) (
Holloway 2005
),
India
(the Great Nicobar Island) (present study).
Remarks:
The present record is the seventh
Anoba
species
from
India
and first from any Indian island.
Anoba rigida
is exclusively a Sundanian species preferring lowland open habitats in secondary, coastal and riverine forests with altitude ranging below
200 m
(
Holloway 2005
).
