SPINELLI, Gustavo R.  and  MARINO, Pablo I.. Current knowledge of the family Ceratopogonidae in Patagonia (Diptera: Nematocera). Rev. Soc. Entomol. Argent. [online]. 2009, vol.68, n.1-2, pp.201-208. ISSN 0373-5680.

Ceratopogonidae includes small nematoceran Diptera which breed in aquatic and semiaquatic habitats. Until the 80´s its taxonomic knowledge in Patagonia was limited to the early 30´s contribution of Ingram and Macfie, from material collected in 1926-27 in the area of the Nahuel Huapi National Park and neighboring sites of Chile. During the last 25 years several projects were performed, many new taxa were described or firstly recorded from the mentioned area. Considering the published data, 102 especies inhabit Patagonia, out of which 86 (84,31%) are endemic. This high percentage is evident in the Nothofagus forests with 71 endemic species, nine are endemic from the steppe and six occur in both biomas. Unpublished data is consistent with this squeme. Nineteen genera are represented in Patagonia, ten widely distributed, three exhibiting transantarctic distribution and six endemic of Patagonia. Revisions of Forcipomyia, Atrichopogon, Borkenthelea, Macrurohelea and Paradasyhelea for the area are published. Those of Dasyhelea and Palpomyia are finished and remain unpublished, Stilobezzia's is almost completed, and studies on Austrohelea, Austrosphaeromias, Physohelea and Bezzia will begin soon. Fifty-five undescribed species are recognized. Regarding biogeographical aspects, there are available studies aimed at establishing relationships between areas recognized in squemes of the Andean region.
