Revision of the Neotropical species of the subgenus Atrichopogon (Psilokempia) (Diptera: Ceratopogonidae).

This revision of the midges in the subgenus Psilokempia Enderlein of Atrichopogon Kieffer provides a brief description of the subgenus, diagnoses, descriptions, illustrations and a key to adult males and females of the 17 species from the Neotropical region, as well as distributional records of both new and previously described species.

Biting midges (Diptera: Ceratopogonidae) from Martín García Island, Argentina.

Nearly 230 species of biting midges have been recorded or described from Argentina; 38 of them are known from the Buenos Aires province and only one is cited from Martín García Island. This paper presents the results raised from six collecting trips which took place on the island during spring 2005, summer 2006 and autumn 2009. Diverse sampling sites including permanent and temporary aquatic environments were chosen, most of the ten sampling sites were ponds of diverse origin, some of these environments were covered with floating vegetation as Lemna gibba, Lemna minuscule, Salvinia biloba, Salvinia minima, Azolla filiculoides, Limnobium laevigatum, Pistia stratiotes, Spirodela intermedia, Wolffiella oblonga and Wolffia columbiana. Other sites were placed in urban and suburban areas. Adults were collected with sweep nets at sunrise and sunset and with light traps at intervals of four to five hours at night, depending on electricity availability on the island. Larvae and pupae were collected with different implements depending on characteristics of each surveyed aquatic habitat. In free standing water, they were captured with small sieves or hand pipettes and micropipettes, flotation techniques were utilized for sampling vegetated areas, free and rooted floating hydrophytes were extracted for removing insects among them. Thirteen species of Ceratopogonidae were collected, three of Atrichopogon Kieffer, three of Forcipomyia Meigen, two of Dasyhelea Kieffer, four of Culicoides Latreille, and one of Bezzia Kieffer, all representing new records from the island.

Alrededor de 230 especies de ceratopogónidos han sido registradas o descritas en Argentina, 38 de ellas son conocidas para la provincia de Buenos Aires y sólo una ha sido previamente citada para la Isla Martín García. En este trabajo se presentan los resultados obtenidos a partir de muestreos realizados en seis viajes a la isla durante la primavera de 2005, verano de 2006 y otoño de 2009; se seleccionaron diez sitios de muestreo con ambientes acuáticos permanentes y temporales. La mayoría de los muestreos se llevaron a cabo en cuerpos de agua de diverso origen; algunos de éstos se hallaban cubiertos con vegetación flotante compuesta por Lemna gibba, Lemna minuscule, Salvinia biloba, Salvinia minima, Azolla filiculoides, Limnobium laevigatum, Pistia stratiotes, Spirodela intermedia, Wolffiella oblonga y Wolffia columbiana; mientras que los restantes se realizaron en zonas urbanas y suburbanas. Los adultos se capturaron con redes entomológicas a la salida y puesta del sol y con trampas de luz a intervalos de cuatro a cinco horas por la noche, dependiendo de la disponibilidad de electricidad en la isla. Las larvas y pupas fueron recolectadas con diferentes metodologías según las características de los ambientes estudiados; en el agua libre se capturaron con tamices pequeños o pipetas y micropipetas, y en cuerpos de agua con vegetación se utilizó la técnica de flotación para separar los insectos de las hidrófitas flotantes y arraigadas. Se identificaron trece especies de Ceratopogonidae, 3 de Atrichopogon Kieffer, 3 de Forcipomyia Meigen, 2 de Dasyhelea Kieffer, 4 de Culicoides Latreille, y uno de Bezzia Kieffer, todos ellos representan nuevos registros para la isla.

(F.) quatei are recorded for the first time from Argentina, and a key is presented for the identification of the seven Neotropical species of the group. Rev. Biol. Trop. 56 (2): 789-794.

(F.) uramaensis, ambas de Venezuela, con las cuales presenta semejanzas morfológicas. Las especies Forcipomyia (F.) argenteola, F. (F.) calatheae y F. (F.) quatei se registran por primera vez en Argentina, y se provee, además, una clave para la identificación de las siete especies Neotropicales del grupo.
