Materials examined. 1 male labelled ‘ Polypedilum insolitum India , West Bengal , Alipurduar , Duars (26.49, 89.53), Coll. T .

The club–shaped apical foreleg and longitudinal medial elevation of the abdomen of P . insolitum and characteristic wing pattern markings and hypopygium structure leads us to conclude that P . insolitum is a junior synonym of Z . marmorata . Distribution . The species has wide distribution occurring in all the Old World zoogeographical realms except the Afrotropical region. The species is reported from Oriental China , Belgium , Czech Republic , France , Germany , Great Britain , Hungary , The Netherlands , and Sweden . The species Z . marmorata is for the first time reported from India in this study.
