Morphometric and molecular characterisation of Tenuiproboscis keralensis n. sp. infecting marine and brackish water fishes from the south-west coast of India with a note on morphological plasticity

Abstract: A new species of acanthocephalan infecting marine and brackish water fishes from the south-west coast of India is described. The parasite belongs to the genus Tenuiproboscis, and the fish hosts include Lutjanus argentimaculatus, L. ehrenbergii, Siganus javus, Epinephelus malabaricus, E. coioides, Scatophagus argus, Parascolopsis aspinosa, Caranx ignobilis, Gerres filamentosus and Lates calcarifer. The parasite inhabits mid- and hindgut regions and is characterised by an elongated, cylindrical, bulbous and post… Show more

“…The riddle for the future research in the family Pomphorhynchidae will be to obtain specimens reliable and representative of most of the species, mainly of the Indian members of the family, for example, the seven species of Tenuiproboscis sp., a poor known genus from Indian marine fishes (Gupta and Naqvi 1992;Amin 2013). Until now, only one species was analyzed using DNA information, Tenuiproboscis keralensis Kaur et al, 2017, while future studies of other Tenuiproboscis species are needed. It is not clear whether it presents a distribution with a clade from each different continent, a visible pattern in other parasites, for example, in the digenean of the genus Clinostomum (Locke et al 2015;Pérez-Ponce de Leon et al 2016).…”

“…The whole intestine was dissected longitudinally and inspected using a stereomicroscope (SZ61, Olympus Life Science) as well as a light microscope (BX3M, Olympus Life Science). The intestine, with attached parasites, was refrigerated in 4°C for 24 h to cause the parasites to detach and evert their proboscis (Kaur et al., 2017). The acanthocephalans were cleaned with lactophenol for light microscopy studies (Li et al., 2017).…”

“…Scanning electron microscopy for Longicollum pagrosomi was performed as described by Kaur et al (2017) with some modifications. Briefly, 2.5% glutaraldehyde in phosphate‐buffered saline (PBS; Na 2 HPO 4 .12H 2 O, NaH 2 PO 4 .2H 2 O and NaCl) was gently poured over a 2 ml centrifuge tube containing parasites for 3 h; followed by 1% osmium tetroxide for 1 h; and then dehydrated in 30%, 50%, 70%, 95% and 100% acetone for 1 h each; critical point dried in liquid carbon dioxide (Hitachi HCP‐2); and gold‐coated in a vacuum‐coating unit (Quorum SC7620).…”
