Description. Externally resembling Cacochroa but segment 3 of labial palpus one-third to one-half length of segment 2; black scales on forewing not raised. In R. sara sp. nov. the forewing is only weakly convex.

Male genitalia ( Figs 3 A–D). Uncus and gnathos absent; tegumen low, rounded; valva broad, expanding from base, costal margin with broad-based digitate process curving outwards, terminal margin with sclerotised hook crossing digitate process then directed outwards, ventral margin extended into a digitate process, inner face with a harpe; juxta with long, pointed, sclerotised, unequal processes, the left longer than the right; vinculum-saccus broad, without anterior extension; aedeagus with or without reflexed base, cornuti various.

Female genitalia ( Figs 4 B–D). Posterior apophysis 2 to 4 times as long as anterior apophysis; segment VIII with nearly straight anterior ventral margin; ostium at anterior edge of segment VIII, more or less concealed by a broad rounded, bell-shaped or bluntly triangular lobe, associated with a tongue-shaped or quadrate flap with terminal setae; antrum tapering to ductus bursae, variously sclerotised; membranous ductus bursae short, gradually or more abruptly expanding to corpus bursae, ductus spermathecae arising from posterior end of corpus bursae, sometimes from a bulge; signum knife or thorn-like with outer margin serrate.

Etymology. The name Rosetea honours the Portuguese lepidopterist Jorge Rosete after whom R. rosetella was named.
