Abstract
    Two new species of Stenheliinae, Stenhelia (D.) schminkei sp. nov. and Melima papuaensis sp. nov. are described from intertidal mud and algal washings from Motupore Island, Papua New Guinea. S. schminkei can be assigned to a species group also containing S. clavus, S. paraclavus and S. valens all described from the Andaman Islands. They share an apomorphic setation pattern of the swimming legs, a confluent female P5 and the special shape of the male P5. The group seems to have only a restricted distribution within the Indo-Pacific region. In describing Melima papuaensis sp. nov. the genus Melima is reinstated as a first step towards a revision of the paraphyletic genus Stenhelia. Autapomorphies for this taxon are defined. A key to the females of Melima is provided. In the course of a phylogenetic analysis of the Thalestridimorpha it turned out, that the "Stenhelia-group" within the traditional Diosaccidae forms a monophylum which can be assigned together with the remaining species of the Diosaccidae and the species of the former family Miraciidae to a common taxon Miraciidae within the Thalestridimorpha. A historical overview and a summary of the discussion is given and an attempt is made to identify some monophyletic subtaxa within the Stenheliinae.
