Taxonomic synopsis of Notiospathius Matthews & Marsh, 1973 (Hymenoptera: Braconidae) from Colombia.

Notiospathius Matthews & Marsh, 1973 is the second most diverse genus of Doryctinae in the Neotropical region, however, in Colombia only two species have been reported and no studies on the diversity of the genus have been conducted. We present a taxonomic synopsis of the genus from Colombia. Principal Component Analysis (PCA) and Discriminant Function Analysis (DFA) allowed the taxonomic evaluation of morphometric characters used by other authors and those proposed in the present study to differentiate the species. Forty seven of 104 characters studied are useful to discriminate the species. Twenty three species are reported. The following new records for Colombia are: Notiospathius angustus Marsh, 2002; N. badius Marsh, 2002; N. bicolor Marsh, 2002; N. ninae Marsh, 2002; N. rugonotum Marsh, 2002; N. shawi Marsh, 2002; N. tinctipennis (Cameron, 1887) and N. venezuelae López-Estrada & Zaldívar-Riverón, 2012. The following 14 new species are described: N. alejandroi sp. nov., N. amazonensis sp. nov., N. carmenae sp. nov., N. cundinamarcensis sp. nov., N. farallonensis sp. nov., N. julianoi sp. nov., N. magdalenensis sp. nov., N. marshi sp. nov., N. payae sp. nov., N. putumayensis sp. nov., N. quimbayensis sp. nov., N. tayronensis sp. nov., N. utriae sp. nov., N. vallensis sp. nov. Notiospathius ugaldei Marsh, 2002 is the junior synonym of N. columbianus (Enderlein, 1912); Notiospathius mariachi Reséndiz-Flores, Nunes and Zaldívar-Riverón, 2014 is the junior synonym of N. carolinae (Marsh, 2002); and N. chinanteco Reséndiz-Flores, Nunes and Zaldívar-Riverón, 2014 is the junior synonym of N. rugonotum Marsh, 2002.
