Systematics of the genus Maietta Alexander with description of three new species (Diptera: Tipulomorpha: Limoniidae)

Abstract

The Neotropical genus Maietta Alexander (Diptera: Limoniidae), endemic to Southern South America (Chile), is revised. Three new species, M. dextra sp. n., M. edwardsi sp. n. and M. sinistra sp. n., are described and illustrated. An identification key is provided for all species. The phylogenetic relationships of the species are investigated in a cladistic analysis, resulting in one single most parsimonious cladogram with the topology ((M. squamigera + M. dextra sp. n.) (M. edwardsi sp. n. (M. trimedia + M. sinistra sp. n.))).

Systematics of Amphineurus (Rhamphoneurus Alexander) (Diptera: Tipuloidea: Limoniidae)

“…The asymmetry in the male terminalia is not uncommon in Amphineurus (e.g., A. (Nesormosia)) nor in the related genus, Maietta (Santos et al 2019). The mesal lobes of these species also have setae concentrated at their apices [88 : 1].…”

“…Alexander (1929a) related the Neotropical genus Maietta with Amphineurus due to the presence of vestiture on the wings. A recent revision of Maietta (Santos et al 2019) reinforced the link between Maietta and Amphineurus. The species M. dextra Santos et al and M. edwardsi Santos et al were, therefore, included in the phylogenetic analysis as outgroup taxa, along with one species of the genus Aphrophila Edwards (i.e., A. neozelandica Edwards).…”
