Ambatoiella clavifemur (Roewer, 1957) comb. nov. Platycynorta clavifemur Roewer, 1957: 89, figs 40–41. Type data Holotype PERU • ♂; western Andean slope, Cajamarca, Llama; alt. 2200 m; 10 Jun. 1956; [Wolfgang Karl] Weyrauch leg.; SMF RII 11652 (examined). Paratypes PERU • 3 ♂♂, 4 ♀♀; same collection data as for holotype; SMF RII 11652 • 4 ♂♂, 4 ♀♀; Cajamarca, Cerro Churun, near Llama, between Chiclayo and Cutervo; alt. 2350 m; [Wolfgang Karl] Weyrauch leg.; Private Collection Weyrauch. Comment The species does not match the diagnosis of Libitioides (which in principle the former species of Platycynorta are expected to be assigned to), and in turn it matches the diagnosis of Ambatoiella. Emended diagnoses for both genera are given here so they can be compared.
