            <p> Chelonibia testudinaria (Linnaeus, 1758)</p>
            <p> Host and location:  Portunus pelagicus, Ha Long and </p>
            <p>Kien Giang, new record for Vietnam.</p>
            <p> Material examined and measured.  Ten live specimens, including 4 specimens from a female crab (87 mm CW, 25 August 2016, locality Ha Long, collector T. Q. Sang) and 6 from a male crab (100 mm CW, 14 May 2016, locality Kien Giang, same collector) . </p>
            <p>Morphological description (Fig.2A–D). Shell conical or evenly rounded, heavy, flat and smooth with a diameter of 7.09 ± 4.75 (1 – 15) mm (n = 10), with 6 calcium plates (1 carina, 1 rostrum, and 4 lateral), solidly joined with each other forming a hard shell surrounding the body. The orifice opening 3.33 ± 1.98 (0.5 – 6) mm long (n = 10), partially covered by 2 tergum and 2 triangular patella (Fig. 2A). Dwarf males found settled on the plates and are distributed randomly (Fig. 2B).</p>
            <p> Infestation status.  Chelonibia testudinaria is recorded as a moderately abundant species (Prevalence 14.82%, mean intensity 9.32 ± 9.96 (Tab. 1 )) and it occupied the outer surface (carapace and limbs), and inside of the sternum (Fig. 2C, D). </p>
            <p> Remarks:  Chelonibia testudinaria is well-known as a successful generalist epibiotic barnacle. It is found on a wide range of marine hosts. Three species of  Chelonibia Leach, 1817 have been described:  C. testudinaria on sea turtles (Rawson et al., 2003; Zardus and Hadfield, 2004; Cheang et al., 2013),  Chelonibia manati Gruvel, 1903 on Sirenians, and  Chelonibia patula (Ranzani, 1818) on crustaceans, e.g. blue crab (Frazier and Margaritoulis, 1990; Bakır et al., 2010; Udoh and Otoh, 2017). Based on genetic characteristics, these three species were later identified as morphotypes of the same species and synonymized under  C. testudinaria (see Cheang et al., 2013; Zardus et al., 2014). Geographically, specific clades were also detected for  C. testudinaria throughout its distribution range such as in the Atlantic, Indian - West Pacific, and Eastern Pacific Oceans (Rawson et al., 2003; Zardus et al., 2014).  Chelonibia testudinaria was previously recorded on  Portunus pelagicus (see Pasternak et al., 2002; Bakır et al., 2010; Babu et al., 2012; Sami, 2018); this, however, is the first record in Vietnam. </p>

            <p> Choniosphaera indica Gnanamuthu, 1954</p>
            <p> Host and Location.  Portunus pelagicus in Khanh </p>
            <p>Hoa, Vietnam.</p>
            <p> Material examined and measured.   All specimens (n = 5) from an ovigerous female crab (125 mm CW, 17 Mar 2016, locality  Nha Trang Bay, collector L. T. K. Oanh)  . </p>
            <p> Morphological description (Fig. 4A–C). The adult female is seed-like and ellipsoid in outline, size 800 – 1200 µm (1014 ± 67.04) × 400 – 700 µm (552 ± 119.57) (n = 5), and the posterior part projects with the caudal styles. The abdomen is fused with the cephalothorax, and the esophagus occupies most of the abdominal cavity.  Choniosphaera indica body is yellow or light pink with two black eyes visible on the head. The cup-like mouth tube is surrounded by the maxillae and the maxillipeds. The mouth is at the bottom of the cup and has a membranous lip(Fig.4A 1). The maxilliped is a long appendage of four unequal segments with the second one longer than the others; it has two short recurved spines and a long, comb-shaped spine on its fourth segment. Two antennas; the first antennae has five articles.The first article bears a spine, the fourth has three spines, and the terminal article carries three spines (Fig. 4A 2). The second antennae are five-segmented. The third article has a spine, and the terminal article carries two long slender spines (Fig. 4A 3). The tail forms two branches, assisting attachment to the crab egg (Fig. 4A, B). </p>
            <p> Infestation status:  Choniosphaera indica occurred with low prevalence (0.29 %), and moderate intensity (20.90 ± 4.97), and was found strictly on the egg mass of the female crab host (Tab. 2, Fig. 4C), no larvae of this species were found. </p>
            <p> Remarks.  Choniosphaera spp. are specific egg eating parasites on decapod crabs. Three species have so far been recorded (Costello et al., 2001; Connolly, 2010), and among them  C. indica is the most common.  Choniosphaera indica was previously reported on  Portunus pelagicus (Shields, 1992; Vo et al., 2013), and considered as a significant contributor to mortality of the crab host, and affecting the host population (Shields and Wood, 1993). Despite being one of the parasites capable of affecting the portunid host species population, no gene sequence of this species is available on GenBank for reference. The present study provides descriptions and images of this species, and also registers two gene sequences(28S rRNA and COI mtDNA) into GenBank. </p>
