Otobothrium muscatense n. sp. (Trypanorhyncha: Otobothriidae) from Rhabdosargus sarba (Forsskål) (Sparidae), with new locality records of larval trypanorhynchs off the Sultanate of Oman

Tentaculariids (Cestoda, Trypanorhyncha) of elasmobranchs from Malaysian Borneo

“…The Coral Triangle is an area of the tropical marine waters with a rich biodiversity (Allen 2007), including elasmobranchs as final hosts for trypanorhynchs, where southern Indonesian waters together with Malaysian Borneo waters are within this recognised zone. Of the 335 valid trypanorhynch species known to date (Haseli & Malekpour Fard 2017; Beveridge et al 2017a; Schaeffner 2018; Beveridge & Schaeffner 2018; Schaeffner & Marques 2018; Shafiei & Haseli 2019; Palm et al 2019, 2020; Beveridge et al 2021; Haseli et al 2021; Oosthuizen et al 2021; Herzog & Jensen 2022; present study), a total of 86 different species (26%) have been recorded until now from Indonesia, and of the 58 tentaculariid species, 21 species (36%) occur in Indonesian waters (Palm 2004; Palm et al 2009, 2019, 2020; Schaeffner et al 2011; Schaeffner & Beveridge 2012a, b, c, 2013a, b, c, 2014; present study). Since most of the trypanorhynch species reported so far off Borneo (see Schaeffner & Beveridge 2014; Palm et al 2020; present study) have also been recorded from Indonesia other than its Bornean part, it seems that the trypanorhynch fauna of Borneo resembles the one from Indonesian waters, since both areas are within the Coral Triangle.…”
