Diplectanids infesting the gills of the barramundi Lates calcarifer (Bloch) (Perciformes: Centropomidae), with the proposal of Laticola n. g. (Monogenoidea: Diplectanidae)

Abstract

Four species of the Monogenoidea, Laticola lingaoensis n. sp., L. latesi (Tripathi, 1957) n. comb. [previously Pseudorhabdosynochus latesi (Tripathi, 1957) Kritsky & Beverley-Burton, 1986], L. paralatesi (Nagibina, 1976) n. comb. [previously Diplectanum paralatesi Nagibina, 1976] and Diplectanum penangi Liang & Leong, 1991, are reported from the gills of Lates calcarifer (Centropomidae) from the South China Sea (new geographical records for L. latesi and D. penangi). Collections from off Bathurst Island, Northern Territory, Australia, represent a new geographic record for L. paralatesi; Chilka Lake, Orissa, India, is established as the type-locality for L. latesi. Laticola n. g. (Diplectanidae) is proposed for species with a spoon-shaped copulatory organ with two to four concentric incomplete ridges in the base. Laticola lingaoensis, the type-species of Laticola, is described, and L. latesi and L. paralatesi are redescribed based on specimens from the South China Sea. Pseudorhabdosynochus monosquamodiscusi Balasuriya & Leong, 1995 and Pseudorhabdosynochus yangjiangenesis Wu & Li, 2005 are considered junior subjective synonyms of L. latesi and L. paralatesi, respectively.

Pseudorhabdosynochusspecies (Monogenoidea, Diplectanidae) parasitizing groupers (Serranidae, Epinephelinae, Epinephelini) in the western Atlantic Ocean and adjacent waters, with descriptions of 13 new species

“…Kritsky & Beverley-Burton [ 25 ] placed all of the above-listed species in Pseudorhabdosynochus as valid species, except that P. epinepheli Yamaguti, 1958 (type species of Pseudorhabdosynochus by monotypy) was considered a junior subjective synonym of P. epinepheli (Yamaguti, 1938) Kritsky & Beverley-Burton, 1986. Yang et al [ 59 ] subsequently transferred P. latesi (Tripathi, 1957) Kritsky & Beverley-Burton, 1986 to Laticola Yang, Kritsky, Sun, Zhang, Shi & Agrawal, 2006 (Diplectanidae).…”

“…Although Pseudorhabdosynochus amplidiscatum (Bravo-Hollis, 1954) Kritsky & Beverley-Burton, 1986 was originally described from Paralabrax maculatofasciatus (Steindachner) (Serranidae: Serraninae) [ 2 ], the species was subsequently reported from two epinephelin hosts [ Epinephelus analogus Gill and Epinephelus labriformis (Jenyns)] from the Pacific coasts of Mexico and Panama [ 30 ]; however, these latter records require confirmation. Two other nominal species of Pseudorhabdosynochus from non-epinephelin hosts were previously reassigned to other diplectanid genera: Pseudorhabdosynochus latesi (Tripathi, 1955) Kritsky & Beverley-Burton, 1986 and Pseudorhabdosynochus seabassi Wu, Li, Zhu & Xie, 2005 both from the latid Lates calcarifer (Bloch), were transferred to Laticola Yang, Kritsky, Sun, Zhang, Shi & Agrawal, 2006 by Yang et al [ 59 ] and Domingues & Boeger [ 5 ], respectively.…”

Diplectanum parvus sp. nov. (Monogenea, Diplectanidae) from Cephalopholis urodeta (Perciformes, Serranidae) of New Caledonia

“…In the shape of MCO, species of this group are similar to members of Laticola Yang, Kritsky, Sun, Zhang, Shi et Agrawal, 2006, but the described species of Laticola have much larger male copulatory organs (Yang et al 2006;Journo and Justine 2006) and a characteristic vaginal structure, not seen in this group. Some members of Laticola have sclerotized vaginal structures (Journo andJustine 2006, Sigura andJustine 2008).…”

“…Most species belong to Pseudorhabdosynochus Yamaguti, 1958(list in Justine 2007a; species of Echinoplectanum Justine et Euzet, 2006, are restricted to members of Plectropomus (see Justine and Euzet 2006); two species of Laticola Yang et al, 2006 have been described (Journo andJustine 2006, Sigura andJustine 2008); and four species of uncertain generic status have been attributed to Diplectanum Diesing, 1858 (Bu et al 1999;Justine 2007a, b;Justine and Sigura 2007). The present paper describes an additional species of 'Diplectanum' from the darkfin hind, Cephalopholis urodeta, which is the first diplectanid described from this fish.…”
