There is very little information available about C ulicoides species ( D iptera: C eratopogonidae) in the western B razilian A mazon. However, studies of the fauna of this region are essential to knowledge of the species and potential vectors within it. Thus, the present study aims to evaluate the abundance, richness and composition of C ulicoides species in rural areas in the state of R ondônia, B razil. C ulicoides specimens were collected in forest and pasture environments in the municipality of P orto V elho, using light traps. A total of 1708 individuals (1136 females and 572 males) belonging to 33 species were collected; 28 of these samples represent new records for the state of R ondônia and include the first record of C ulicoides contubernalis in B razil. C ulicoides insignis was the most abundant species (86.1%). Species richness was greater in forest areas (32 species, 96.96%), whereas pastures presented the greatest number of C ulicoides captured ( n = 1540, 90.1%). This study shows that C ulicoides populations differ between forest and pasture environments and indicates that the abundance of C . insignis is an important factor in epidemiological vigilance studies in the region.
