A Review of New Zealand Porricondylinae (Diptera: Cecidomyiidae)

Abstract

Abstract. Five genera of the mycophagous subfamily Porricondylinae are reported for the first time to occur in New Zealand, namely Asynapta, Camptomyia, Colomyia, Divellepidosis, and Paratetraneuromyia. New species in these genera, all to be attributed to both authors, are described and named Asynapta bicornis, Camptomyia rakiura, Colomyia inexpectata, Divellepidosis constricta, D. eximia, D. tewaipounamu, Paratetraneuromyia denticulata, and P. multidenticulata. The genus Yukawaepidosis, previously monotypic and ill-defined, is shown to have a second, previously unnamed species, which is described as Y. kaikoura and compared with Y. aliculata (Yukawa). The generic definition of Yukawaepidosis is revised. All species descriptions are based on the morphology of males caught in flight (i.e., Nothing is known on the habitat and biology of the larvae.). Altogether, New Zealand's Porricondylinae are now known to comprise 33 species in eight genera, representing all the three tribes recognized in this subfamily, namely Asynaptini, Dicerurini and Porricondylini.
