1. both specimens are suspected to be juveniles (Lewis, 2011a);
4. the single known specimen has been considered a juvenile (Chagas Junior & Shelley, 2003);
5. measured specimens up to 12 mm long belong to either this species or the very similar G. minimus, and a single specimen of G. piae has been measured 15 mm long but it features as an outlier (Zapparoli, 2011);
6. the taxonomic position is uncertain, possibly a species of Ribautia (Pereira, 2014);
7. the single known specimen has been reported as a female (Pereira et al., 2006), but the anatomy of the genital region suggests a juvenile without gonopods;
8. the measure has been taken including the antennae (Attems, 1907).
