Differential diagnosis Species with vein R4+5 straight, metafemur without basoventral patch of black setulae, arista bare, face carinate ( Fig. 4F ) and metafemur greatly enlarged with a ctenidium on the posteroventral half. It is similar to S. oceanica , but differs by having the spurious vein well sclerotized ( Fig. 5C ), as distinct as the neighboring R and M veins (spurious vein not sclerotized in S. oceanica , only formed by microtrichia; Fig. 5B, E ), the ventral surface of the metatibia with an anteroventral carina forming a prominent lamina in males, less evident in females (metatibia without lamina in S. oceanica ) and a distinct abdominal coloration, as stated in the key.
