259: BOTHIDAE (LEFTEYE FLOUNDERS)
Durban to St. Lucia Bay, possibly reaches East London
(33°05'S) and Machanga (Mozambique); India and Ceylon;
unconfirmed records from Madagascar, Comoro Ids.,
Somalia, Japan and Hong Kong.
Genus Engyprosopon Gunther, 1862
Several species; 3 in our area. E. sp. has been collected
from Porto Amelia, Mozambique, and E. macrolepis
Regan, 1908 is known from the Comoro Ids. and Cargados
Garajos; a 25.6 mm SL specimen from Sodwana Bay is tentatively identified as E. macrolepis.
