Chaetura andrei meridionalis
Santiago del Estero, Argentina.
Until recently considered a race of C. andrei, but latter now adjudged a subspecies of C. vauxi and present form (which is much longer-winged and longer-tailed than C. v. andrei, and with different underpart pattern) found to be extremely close morphologically to C. pelagica (best separated by differences in wing formula, as P9 is 3–8 mm longer than P10 whereas in C. pelagica both are equal), so possibility of conspecificity high#R; study needed. Monotypic.
E & SE Bolivia, SE & S Brazil, Paraguay and N Argentina; winters N to Panama, Colombia and French Guiana.
