RESUMEN “Culicoides (Diptera: Ceratopogonidae) del estado de Ceará, noreste de Brasil: Diversidad, nuevos registros y enfoques bionómicos”. Introducción: poco se sabe sobre la biodiversidad del género Culicoides y la posible presencia de especies de vectores en el estado de Ceará, Brasil. Objetivo: mejorar el conocimiento de la biodiversidad y la posible presencia de vectores en el noreste de Brasil. Métodos: utilizamos trampas luminosas CDC, realizamos un levantamiento de las especies de Culicoides en 18 municipios pertenecientes a seis mesorregiones del estado de Ceará. Resultados: un total de 1 453 ejemplares (12 especies) recolectamos. Culicoides guyanensis fue la especie más abundante correspondiendo al 75,84% de los especímenes recolectados. Culicoides venezuelensis está bien distribuida en cinco de las mesorregiones investigadas. Cinco especies reportamos por primera vez para el estado de Ceará y siete especies para los municipios de las mesorregiones estudiadas; discutimos la presencia de especies de importancia sanitaria. Conclusión: con la adición de nuevos registros de especies, existen ahora 12 especies conocidas para el estado de Ceará. La presencia de especies con importancia médica y/o veterinaria en las mesorregiones estudiadas es indicativa de la necesidad de una vigilancia epidemiológica en el estado.

ABSTRACT Introduction: little is known about the biodiversity of the genus Culicoides and the possible presence of vector species in Ceará State, Brazil. Objective: to improve the knowledge about the biodiversity and possible vectors presence in northeastern Brazil. Methods: with CDC light traps we surveyed Culicoides species in 18 municipalities from six mesoregions of Ceará State. Results: we collected 1 453 specimens (12 species). Culicoides guyanensis was the most abundant species, with 75,84% of the collected specimens. Culicoides venezuelensis is well distributed and is found in five Mesoregions. We recorded five species for the first time from Ceará State and seven from the surveyed municipalities; the presence of species with sanitary importance is discussed. Conclusion: with the addition of new species records, there are now 12 species known from Ceará State. The presence of species with medical and/or veterinary importance in the studied Mesoregions is indicative of the need of epidemiological surveillance in this state.

Uma nova espécie do grupo reticulatus, C. castelloni Santarém e Felippe-Bauer, é descrita e ilustrada baseada em espécimes fêmeas do estado do Amazonas, Brasil.

This paper further presents a new record of Culicoides pseudoheliconiae Felippe-Bauer out of the previously defined geographic distribution of the hylas species group, in the province of Misiones, Argentina.

O macho de Culicoides horticola Lutz, 1913 é descrito e ilustrado com base em espécimes coletados no departamento de Madre de Dios, Peru, e no estado do Rio de Janeiro, Brasil. Culicoides bachmanni Spinelli, 2005 é considerada como sinônimo júnior de C. horticola. Citações e descrições anteriores de C. horticola são discutidas e a espécie é reportada pela primeira vez para o Peru e picando humanos.

The male of Culicoides horticola Lutz, 1913 is described and illustrated from specimens collected in the Department of Madre de Dios, Peru, and in the State of Rio de Janeiro, Brazil. Culicoides bachmanni Spinelli, 2005 is considered as a junior synonym of C. horticola. Previous citations and descriptions of C. horticola are discussed, and the species is firstly recorded from Peru and biting humans.
