Diplectanids (Monogenoidea : Dactylogyridea) from the gills of marine fishes of the Persian Gulf off Kuwait

Seventeen species of Diplectanidae were collected from the gills of 17 spec ies of marine fishes from the Persian Gulf off Kuwait. Lepidoterma kuwaiten sis sp. n. from Terapon puta (Teraponidae), Lamellodiscus furcillatus sp. n . from Diplodus nod (Sparidae), and Protolamellodiscus senilobatus sp. n. f rom Argyrops spinifer and A. filamentosus (Sparidae) are described. Diplect anum cazauxi from Sphyraena jello and S. obtusata (Sphyraenidae) (new host and geographic records), D. sillagonum from Sillago sihama (Sillaginidae) ( new geographic record), Pseudolamellodiscus syhyraenae from Sphyraena chrys otaenia (Sphyraenidae) (new host and geographic records), and Calydiscoides fleuxuosus from Nemipterus peronii and N. bipunctatus (Nemipteridae) (new host and geographic records) are redescribed. An incidental geographic reco rd for C. flexuous on N. japonicus from the western coast of India is inclu ded. Ten diplectanid species From 8 hosts were unidentified for lack of suf ficient specimens. Diplectanum longipenis (synonym: Squamdiscus longipenis) is transferred to Lepidotrema. Squamodiscus is removed from synonymy with Diplectanum and becomes a junior subjective synonym of Lepidotrema. Calydis coides indianus (synonyms: Lamellospina indiana and C. indicus) is a junior subjective synonym of C. flexuosus.
