REMARK

Although our male specimens fit on descriptions of this species made by Bergroth (1910) and Grazia (1983), these specimens ( Fig. 2B ) do not agree completely with the pygophore illustration of Grazia ( Grazia 1983: 178, fig. 1 and Fig. 2A ). Shapes of ventral and dorsal rims of the pygophore look similar but parameres from our specimens are much smaller, never go beyond the ventral rim and their tridimentional form is not clearly represented in the illustration. Bergroth (1910) and Grazia (1983) mentioned this species was previously collected from French Guiana, but no locality was reported. This species is the most “common” Phalaecus species, and it is actually well distributed among nine municipalities all over French Guiana. More than a third of the specimens were collected with UV-MV light traps, and about two third were attracted by LED automatic light traps. Since the previous distribution reported by Grazia (1983), this species was also mentioned from Colombia by Torres Gutiérez (2005).
