F. 37 (2/3): 145–158 (2016) 145 An illustrated and annotated checklist of Philiris Röber, 1891, taxa occurring in the Indonesian provinces of North Maluku and Maluku (Lepidoptera: Lycaenidae) Andrew Rawlins and Alan Cassidy Andrew Rawlins, 392 Maidstone Road, Rainham, Kent, ME8 0JA, UK; [email protected] (corresponding author) Alan Cassidy, 18 Woodhurst Road, Maidenhead, Berkshire, SL6 8TF, UK; [email protected] Abstract: This paper recognises 16 taxa (8 species) of the In producing this checklist we have relied heavily on the ly caenid genus Philiris Röber, 1891 that occur in the In do collections of the Natural History Museum, Lon don.

Some Biogeography and definitions of North Maluku new island locality records are introduced, maps show all the islands discussed in the text and all taxa are illustr at ed and Maluku in colour. In this paper we use the term Maluku to incorporate the Keywords: Lepidoptera, Lycaenidae, Philiris, new sub spe cies, two Indonesian provinces of North Maluku (= Malu ku new locality records, Indonesia, North Maluku, Ma lu ku.
