Abstract

A new genus and 15 new species of caddisfl ies are described from Batanta Island of West Papua, Indonesia: Horvathomina gen. n., Chimarra kalija sp. n., Horvathomina gergoi sp. n., H. akosi sp. n., H. martoni sp. n., Tinodes topor sp. n., T. vagot sp. n., Nyctiophylax (Paranyctiophylax) egyes sp. n., Polyplectropus ollos sp. n., P. pohos sp. n., Abacaria kovacsi sp. n., Goera batanta sp. n., Triplectides dombos sp. n., T. karimas sp. n., T. rojtos sp. n. and T. sugaras sp. n. New records of 40 species are given. Details of fi ne structure analysis of paraproct are discussed. Th e ancient plesiomorphic and derived apomorphic character states are surveyed in genera of the family Ecnomidae. Taxonomic value of wing venation, spur number and genitalic traits are evaluated for species elimitation in the genus Triplectides Kolenati, 1859. Harpagones and mesal lobe of the gonopods in Triplectides are non-neutral adaptive traits under directional sexual selection, and provide consistent and stable fine structure to delimit species boundaries. With 73 fi gures.
