Neodexiopsis Malloch (Diptera, Muscidae) from Ecuador: description of new species and a key to the species

ABSTRACT

ABSTRACT Neodexiopsis Malloch (Diptera, Muscidae) is a member of the subfamily Coenosiinae, with more than a hundred species recorded in the Neotropical region. In Ecuador, it is known by four species, which may be an underestimated number. We describe five new species based on recently collected material: Neodexiopsis bicoloratta new species, N. longialata new species, N. nigrocalyptrata new species, N. plana new species, and N. secunda new species. A key to segregating all the recorded species from Ecuador is presented. The male and female terminalia of the new species were dissected and illustrated. Images of the habitus of the adult from the new species are presented.
