259: BOTHIDAE (LEFrEYE FLOUNDERS)
Larvae as illustrated; metamorphosis occurs at a large
size. Eyed side brownish; median fins and P of eyed side
darker. Attains 19 cm. Natal, Delagoa Bay and Mombasa in
180 - 310 m.
259.13 Laeops pectoralis: top: 12 em SL (Kenya); bottom: larva, 4.5 em SL,
holotype of Parabothus thackwrayi.
Genus Mancopsetta Gill, 1920
Achiropsetta Norman, 1930, Apterygopectus Ojedo, 1978
and Neoachiropsetta Kotlyar, 1978 are junior synonyms.
Genus poorly known; familial placement questionable,
possibly most closely related to the Rhombosoleinae (dextral); widely distributed in southern oceans. Five nominal
species, possibly 3 or 4 valid; 1 in our area. However, M.
maculata (Gunther, 1880) has been collected near Marion
and Prince Edward Ids.
