Simulium (Inseliellum) littopyga Craig & Evenhuis, n. sp.

Etymology. In reference to inhabiting beaches; deriving from litto [= “beach”] + pyga [= “rump”]; hence a “beach bum” of sorts. The name is treated as a noun in apposition.

Simulium (Inseliellum) littosocius Craig & Evenhuis, n. sp. 

Etymology. In reference to the association with beaches; deriving from litto [= "beach"] + socius [= “companion”]; hence a second “beach bum” of sorts. The name is treated as a noun in apposition. 
Distribution. Known from Tahiti and Raiatea.


Simulium (Inseliellum) littosodalis Craig & Evenhuis, n. sp.

Etymology. In reference to occurring with other beach simuliids; deriving from litto [= “beach”] + sodalis [= “comrade”, “crony”]; hence a third “beach bum” of sorts. The name is treated as a noun in apposition.
