Dalima Moore
Type species: apicata
Moore, India.
Synonyms: Calladelpha
Warren (type species patnaria Felder = schistacearia Moore,
India); Holoboma Warren (type species bucens Warren, N.E. Himalaya);
Homoeoctenia Warren (type species subflavata Felder); Leptostichia
Warren (type species batitans Warren, N.E. Himalaya); Metoxydia Butler
(type species cabamina Butler, N.E. Himalaya); Panisaba Moore
(type species truncataria Moore, N.E. Himalaya).
This genus is
diverse and difficult to define. It contains mainly large species with the
forewing usually slightly falcate at the apex and weakly foveate in the male.
The hindwing apex is often excavate between Sc and Rs, sometimes with a tail
between Rs and M1. The antennae of the male are strongly bipectinate to about
four fifths, those of the female more weakly so or ciliate. The facies tends to
be of the delineata/mjoebergi type (Metoxydia) or more as in subflavata
or patubaria (the majority).
The male abdomen has
a setal comb on sternite 3 in most species dissected. The uncus is usually
apically bilobed. The valve has the cucullus strong, with a sclerotised band
extending from it obliquely basad to the sacculus, usually with some sort of
spinose process more or less at its centre. The juxta is usually apically
produced or has a hollow digitate process centrally. The aedeagus vesica is
simple, scobinate in parts, but lacks cornuti.
In the female
genitalia the signum is weak or absent, not mushroom-like, and the ostium bursae
is usually set in a zone of membranous folding anterior to the eighth segment.
The genus is
Oriental, with its greatest diversity in the N.E. Himalaya.
