Abstract

Perulernaea pirapitingae n.sp. a parasitic copepod (Lemaeidae) from the fish Piaractus brachypomus of
the Meta River, Colombia, is described. In addition to the postmetamorphic female, observations on the
copepodid V, the premetamorphic female and transitional stages are presented. The new species differs
from the only other species known in the genus, Perulernaea gamitanae THATCHER & PAREDES, 1985,
by being only about half as large, having less extensive "neck" glands and a leg 2 that is in a more anterior
position. The new species also has a different host and is from another country.
