Mumetopia interfeles sp. nov., a new species of Anthomyzidae (Diptera) occurring en masse in an urban grassy habitat in Chile: its taxonomy, phylogeny and biology

A new species of Anthomyzidae (Diptera), viz., Mumetopia interfeles Roháček sp. nov. (both sexes), is described from Chile, based on a large series collected small grassy area (consisting non-native species, Hordeum murinum L.) among houses in the city Valparaíso. Its systematic affiliation, phylogenetic relationships, and biology are discussed. Cases mass occurrence adult Anthomyzidae, particularly those anthropogenic habitats, reviewed general features them hypothesis proposed for relationships Chamaebosca group genera within (64 dataset), Bayesian inference maximum likelihood analyses seven DNA markers (12S, 16S, 28S, COI, COII, CytB, ITS2). Taxonomic limits genus Melander, 1913 Based molecular previous cladistic analysis morphological data (Roháček & Barber 2009), broadened, better-supported concept (s. str.) to include M. (and its unnamed relatives) externally aberrant, undescribed endemic Juan Fernández Islands. Apart (M. only), community Diptera associated with H. was dominated by phytophagous Chloropidae: Ceratobarys sacculicornis (Enderlein, 1911) occurred extremely high numbers similar nov., while less abundant Opetiophora represents first record South America.
