ABSTRACT
This catalogue presents 70 species distributed in two genera for Colombia: Gigantodax with 5 groups, and Simulium with 6 subgenera and 17 groups. Three species are recorded for the first time: Gigantodax vulcanius, G. gracilis, and Simulium pautense, and the distributional range is expanded to S.ochraceum, S. paynei, S. metallicum, and S. callidum.

The Membracidae are a relatively diverse group with nearly 400 genera and 3200 species. For Colombia 93 genera and 394 species were previously known. Study of the literature and 3744 specimens deposited in ten colections in Colombia, as well as non-systematic collections and field observations done in Colombia between 2011 and 2014, led us to record 116 genera and 474 species grouped in 9 subfamilies and 23 tribes, distributed in 24 departments. Thirteen genera were new country records. In addition, 1449 records of host plants and 262 records of associated Hymenoptera were obtained from literature, the examined collections and new, non-systematic field trips. For each genus a differential diagnosis is presented, as well as notes on biology, distribution and some taxonomic comments. Illustrated keys for the genera of Colombian Membracidae and known distributional maps are given. After examination of several Anobilia species, we propose the new combinations Stilbophora flava (Tode, 1966) n. comb., Stilbophora luteimaculata (Funkhouser, 1914) n. comb., Stilbophora sagitatta (Tode, 1966) n. comb., Stilbophora silvana (Tode, 1966) n. comb., Stilbophora tripartita (Fairmaire, 1846) n. comb., and Stilbophora variabilis (Tode, 1966) n. comb. The male of Sakakibarella sinuosa Creão-Duarte is described.

The genus Glyphidops Enderlein, 1922, the most widespread and speciose of the New World genera of Neriidae (Diptera), is revised herein. Glyphidops (Glyphidops) ruselatus, new species, G. (G.) steyskali, new species and G. (G.) coracinus, new species are described. Of the 16 previously described species, which were last treated by Aczél (1961), the following synonyms are proposed: Chaetomeristes peruanus Enderlein is treated as a junior synonym of G. (G.) bullatus (Enderlein); Nerius dispar Cresson, Oncopsia neutra Hennig and Oncopsia dubia Hennig are treated as junior synonyms of G.(O.) durus (Cresson) and Oncopsia seductrix Hennig, is treated as a junior synonym of G. (O.) flavifrons (Bigot). The species Telostylus vittatus Cresson, is removed from synonymy with G. (G.) filosus (Fabricius) and revalidated as senior synonym of G. ochreus Hennig. A new diagnosis for the genus and all species are provided, as is an identification key to species. New locality records are provided for Costa Rica, Colombia, Venezuela, Guyana, Ecuador and Brazil.

Here we revise Eoneria Aczdl, 1951, a small genus of flies in the Neriidae, previously known from two species from Argentina. We describe a new species, E. aczeli Sepúlveda & Carvalho from Colombia, provide new records from Brazil, a distribution extension from Argentina and a new genus diagnosis, as well as an identification key based on adult morphology.

Se realizó un seguimiento bimensual durante un año, en dos fincas lecheras del Municipio de Fredonia, Antioquia, en mamíferos silvestres, vectores incriminados y en hatos centinelas, con el objetivo de determinar por seroneutralización los porcentajes de animales infectados con el virus de la Estomatitis Vesicular, realizar intentos de aislamiento viral en cada una de estas poblaciones, y detectar fragmentos del genoma viral por RT-PCR y PCR anidado. Se encontró que el porcentaje de infección fue del 57.14 por ciento para el serotipo Indiana (IN) y del 73.01 por ciento para el New Jersey (NJ), igualmente se determinó que el 37.5 por ciento de los animales silvestres capturados mostraron bajos títulos de anticuerpos, 1:8 principalmente y solamente contra el serotipo IN, lo cual parece sugerir que el ciclo de infección en la fauna silvestre no está relacionada con el ciclo en los animales domésticos. De otro lado todas las muestras de sangre de reservorios y macerados de insectos procesadas por las técnicas moleculares mencionadas mostraron resultados negativos. Se discuten los resultados y se proponen nuevos estudios.
