Syritta aenigmatopatria
Hardy, 1964: 409
(
holotype
:
♂
,
BPBM
; type locality:

,
Oahu
).
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.
