French Guiana , Belizon , xi.2001 , H. Gaspard leg., 2 males (MNRJ) . Racelda robusta was described based on a male from French Guiana ( Berenger and Gil-Santana 2005 ). Gil-Santana et al. (2013) recorded the species from Brazil ( Amazonian region ). They observed that while the holotype had the center of hind lobe of pronotum entirely blackish, the male from Brazil had a less extensive blackish coloration, with a pale portion below the transverse sulcus. In the males from French Guiana examined here, the area below the tranverse sulcus is also pale to some extent, except at medially (Fig. 56 ), suggesting intraspecific rather than geographic variation in the size of this blackish marking .
