| Abstract: | The win structure of the New Zealand nannochoristid currently known as Microchorista philgotti: (Tillyard, 1917) is described and discussed. Tubular wing vein sclerotizations are developed in the uper win cuticle only. Shortening of the hindwing CuP-A anastomosis to a single point cannot ge uphed as a nannochoristid autapomorphy. Absence of the Rs3-Rs4 crossvein (the diagnostic character for Microchorista) and, perhaps, presence of specialized microtrichia patches on the fore wing are autapomorphic of the New Zealand species. Since the genus Nannochorista, comprising the Australian/Tasmanian and S. American nannochoristids, according to available evidence is paraphyletic in terms of Microchorista the latter is synonymized with the former. |
