Resumo: 	Males of Euglossa mandibularis Friese, 1899 can be categorized by (1) presence or (2) absence of scutellar tuft (a morphological feature of dense setae found in females' scutellum of the genera Euglossa Latreille, 1802 and Eulaema Lepeletier, 1841). A multivariate statistical analysis using six morphological measures (hindtibia length and width, head width, intertegular span, midbasitarsus length and scape length) show that males of the categories 1 and 2 were significantly different in relation to such measures. The width head, hindtibia length and scape length were the measures that most influenced the observed differences. Levene test suggest there is not effect of stabilizing selection on males without scutellar tuft. Since there is a fluctuation in the proportion of males with scutellar tuft occurring in a single population, the observed morphological differences might be environmentally determined.
