Based on literature and the study of 345 specimens, four species are known and two are likely to be present in French Guiana. A key to species and a list of data are provided. A multiple correspondence analysis (MCA) showed that the three main localities are somewhat distinct, as well as the years 2007-2008 and 2011. Phenology shows that species are flying all year round, with a wide peak of H. cavifrons and H. curvatus during the dry season and early rainy season, fact also shown by the MCA results. On the contrary, H. diadema is more abundant during the first half of the year (rainy season). Monthly abundances appear to be significantly correlated with rainfalls of the previous 2nd and 7th months for H. cavifrons, 2nd and 3rd months for H. curvatus. However, the lack of knowledge of the biology of the species(developmental time, number of annual generations) prevents any hypothesis to be confirmed.
