Heteroplectanum n.g., a new genus of Diplectanidae Bychowsky, 1957 (Monogenea, Monopisthocotylea), parasites of marine teleosts from Madagascar

Heteroplectanum n.g., a new genus of Diplectanidae Bychowsky, 1957 (Monogenea, Monopisthocotylea), parasites of marine teleosts from Madagascar

Heteroplectanum n.g. is erected on the basis of 4 new species of Diplectaidae found on the gills of marine fish in Madagascar. The new genus is characterized by a haptor with 3 transverse bars, 2 pairs of hamuli at the lateral tip of the dorsal bar, 2 squamodiscs formed by 2 rows of vertebra-shaped pieces in divergent rows (the first of which form a V), 3-4 pairs of cephalic glandular organs, 2 pairs of eye spots, a complex penis and a sclerified or non-sclerified vagina.

The 2 species occupy slightly different niches on t...
