A generic diagnosis for the genus Semiocladius Sublette et Wirth and a key to the male imagines is given. The systematic position of the genus is close to Thalassosmittia Strenzke et Remmert based on imagines and pupa while the tentatively associated larva possibly could belong to another genus with marine larvae. Semiocladius crassipennis (Skuse), S. endocladiae (Tokunaga) and S. brevicornis (Tokunaga) are redescribed in both sexes, and the presumptive larva of S. kuscheli Sublette et Wirth redescribed. A pupa collected from Lord Howe Island in the Western Pacific Ocean is described, illustrated and tentatively assigned to the genus. The generic diagnosis for pupae is expanded to include this species.
