Schizochoerus janickii
Nesolecithus janickii
Klaus RohdeIntroduction
Like Schizochoerus liguloideus, this species is known from the body cavity of Arapaima gigas (Clupeiformes) in the Amazon. Maximum length is 86 mm, maximum width 22 mm. Eggs lack a stalk. The species can easily be distinguished from Schizochoerus liguloideus in the same host by its wider body and the much shorter accessory seminal receptacle. It is distinguished from Nesolecithus africanus mainly by the shape of the accessory seminal receptacle (of uniform length in N. janickii and consisting of a narrow basal and wide distal part in N. africanus).
