Two new species of Pipunculus Latreille, 1802 (Diptera: Pipunculidae) from Colombia, and an updated key to males of the Neotropical species

Pipunculus Latreille, 1802 is a cosmopolitan genus of big-headed flies (Pipunculidae), with 12 known species in the Neotropical region, and three in Colombia. Two new species of Pipunculus are described from Colombia, namely Pipunculus geua sp. nov. (type-locality: Páramo de Santa Inés, Belmira) and P. nutabes sp. nov.

(type-locality: Páramo de Santa Inés, Belmira). Illustrations and a new dichotomic key to the Neotropical species are presented. This paper increases the number of Neotropical Pipunculus from 12 to 14, from five to seven in South America and from three to five in Colombia, which is now the South American country with the highest diversity of this genus.
