The predaceous genus Stilobezzia Kieffer is a large, diverse group of Ceratopogonidae that is worldwide in distribution except for Antarctica and some islands (Borkent 2014). Adult females are important predators on other small insects, and the immature stages are found in a wide variety of aquatic and semiaquatic habitats, including streams, lakes and pondmargins, puddles, swamps, rice fields, rock pools, and tree holes (de Meillon and Wirth 1991; Cazorla et al. 2006). Four subgenera are included within the genus, Stilobezzia Kieffer, Acanthohelea Kieffer, Debenhamia Wirth & Grogan and Eukraiohelea Ingram & Macfie. Currently, the cosmopolitan Stilobezzia (Acanthohelea) is represented in theNeotropical Region by 37 species (Borkent, 2015; Cazorla & Spinelli 2015). Recently, the examination of a large collection of species of the genus Stilobezzia from the state of Rondônia in Brazil, resulted in the finding of two new species of Stilobezzia (Acanthohelea) which are herein described and illustrated.
