Type material. Ovigerous female, Rijksmuseum von Natuurlijke Historie, RMNH (No. I. 67) (see Trilles et al. 2012).
Type locality. Batavia Sea (= Java, Indonesia).
Type host. Bleeker (1857) did not specifically state the type host and site attachment except for a generic comment “ Habite la peau de diverses especes de poissons ” which translates to “Living on the skin of different host species”.
Material examined. 1 ovig ♀ (12.55 mm TL; 5.68 mm W) (UMT Crus 01158), 1 mature ♁ (7.94 mm TL; 2.10 mm W) (UMT Crus 01159), stretch of beach along the Institute of Oceanography and Environment, Universiti Malaysia Terengganu, 05°24.927’S; 103°5.2531’E, 8 March 2020, coll. Yusri Yusuf.
Host. Carangidae and Engraulidae: Stolephorus indicus (van Hasselt, 1823) (Trilles, 1979), Carangoides malabaricus (Bloch & Schneider, 1801) (refer to Trilles et al. 2012), Alectis indica indicus (Ŗppell, 1830) (see Anand Kumar et al. 2017), Rastrelliger kanagurta (Cuvier, 1816) (Ravichandran et al. 2019).
Distribution. Indonesia (Bleeker 1857; Trilles 1979); southeast coast of India (Trilles et al. 2012; Ravichandran et al. 2019); Malaysia, off the coast of Miri (Anand Kumar et al. 2017).
Remarks. Catoessa boscii can be identified by the elongate body shape and slender pleon; pleon slightly rotated with oblique angle against pereon plane; cephalon not immersed in pereonite 1, anterior margin truncated, reflexed ventrally into triangular lobe separating antennulae; posterior margin of pereonite 7 slightly concave. The genus contains three other species known to occur from the Pacific and Indian Oceans: Catoessa ambassae Bruce, 1990 from Australia; Catoessa gruneri Bowman & Tareen, 1983 from Kuwait and India; and Catoessa scabricauda Schioedte & Meinert, 1884 from Indonesia. Catoessa boscii was only recently reported as a new record for Malaysia from Miri, Sarawak by Anand et al. (2017) who reported the species in the buccal cavity of the host species Alectis indica (22% prevalence; 1.25 mean intensity).
