Identification. Both males and females of R. hambletoni could be reliably identified. The pronotum is short, not covering the mesonotum ( Fig. 11E, G), like in other species of the angustipes complex ( Polhemus 1997). Males lack a spine on the fore trochanter, have black middle coxa ( Fig. 11F), bear about seven spines on the hind femur, display shiny black areas dorsally on the center of abdominal segments V–VIII ( Fig. 11E), and have laterotergites gradually tapering posteriorly ( Fig. 11E). Females have hind trochanter yellowish ( Fig. 11H), hind femur with three to five spines, and abdominal lateroter- gites reflected over the mediotergites ( Fig. 11G) (Moreira 2012).
