The present research work deals with theTaxonomic Relevance of Internal male genitalia in subfamily Arctiinae (Arctiinae:Arctiidae:Lepidoptera) collected from North-East India. The collection-cum-survey tours to various North-Eastern States viz. Assam, Arunachal Pradesh, Manipur, Mizorum, Nagaland, and Sikkim, yielded a rich harvest of 1670 adult representatives of subfamily Arctiinae. From this collected lot, as many as 39 species under this subfamily has been identified with the help of literature and confirmed by comparison. All these species have been dissected and preserved in the field...

Taxonomic work on lithosiinae group of moths got initiated in the Department of Zoology and Environmental sciences, Punjabi University, Patiala in 1994. Since then many taxa have been published, updated and revised by Kirti and Singh (1994, 1994a, 1995, 1995a, 1996, 2000). Studies on the internal reproductive organs of subfamily Lithosiinae have been undertaken for the first time in this country. The internal reproductive features are species specific structures and enable to update the diagnosis of various taxa in family Arctiidae. In the present work studies on male internal reproductive...
