Rhanidopsis
West
Type species: neophantes
West, Philippines (Luzon).
Species in this genus
are small, a dull grey-green, with irregular fawn, white and brown medially. On
the hindwing these bands consist of, proceeding distally, narrow white, broad
fawn, broad dark brown speckled with white, and further
fawn
elements. These recur weakly over the tornal third of the forewing, where there
is also a pale zone on the dorsum between this band and the base of the wing. In
the type species from Luzon this latter is narrower, more irregular, whitish: it
is broader, semicircular in the Bornean species. The forewing costa and margin
are also suffused with darker, duller fawn.
The male antennae are
regularly and moderately bipectinate to about two-thirds, those of the female
more narrowly and robustly bipectinate. The female specimens of the type species
have the forewings rather more elongate, with the distal margins more curved: a
male from Luzon (see below) and a putative male from Palawan are shaped as in
Bornean males.
In the male genitalia
the uncus and socii are modified into a lyre-like structure. The gnathus is
apically bifid or bilobed, rugose. The valves are hastate, tapering. The costal
thickening terminates in a small row of spines. The saccus is simple, well
developed. There are no setal patches on the third sternite.
In the female (Fig 374)
the ovipositor lobes are of the modified type. The ductus is slender, relatively
long: the bursa is spherical, with a weak signum. The sterigma is trilobed.
The placement of this
genus to subtribe is problematic. The hindwing venation is as in the Hemitheiti,
but the genitalia features, particularly the uncus structure, are atypical.
