ANEW GENUS MANGINA ALONG WITH THE TAXONOMY OF
ARGINA HUBNER (ARCTIINAE: ARCTIIDAE: LEPIDOPTERA)

(With eleven text-figures)
Key words: Argina Mangina genitalia, congeneric
, ,
The taxonomy ofgenus Argina Hubner has been revised by incorporating the male and
female genital features ofthe type species astrea (Drury). Another Indian species argus
Kollar, earlier described under Aigina Hubner, has been found non-congeneric on the
basis of its genital structures. A new genus Mangina has, therefore, been proposed for
argus Kollar. The new genus is closely allied toArgina HQbner.
