Abstract
Two species of Pseudodiscocotyla Yamaguti, 1965 (Monogenea: Discocotylidae) were collected from crimson jobfish Pristipomoides filamentosus (Valenciennes) (Perciformes: Lutjanidae) off Okinawa-jima island, southern Japan. Pseudodiscocotyla opakapaka is redescribed and represents the first Japanese record. A new species, Pseudodiscocotyla mikiae n. sp., differs from Ps. opakapaka in the absence of spines around the male genital pore, the shape of the vaginal pore, the presence of spines inside the vaginal pore, and the shape of the clamp. The locations of the male genital atrium and the vaginal pore in both species were similar, and the observed armament differences of the male copulatory organ are therefore presumed to establish reproductive isolation. The phylogenetic trees for the Mazocraeidea based on the partial 28S rDNA sequences were created using new sequences of Pseudodiscocotyla mikiae n. sp., and Discocotylidae formed a sister group with the species Diclidophoridae, Macrovalvitrematidae, and Plectanocotylidae. Pristipomoides filamentosus is widely distributed across the Indo-Pacific, and Pseudodiscocotyla mikiae n. sp. could share the distribution of the host.

Abstract
A new monogenean species, Kannaphallus leptosomus n. sp., from the gills of the diamond trevally, Scyris indica Rüppell, caught off Terengganu, Peninsular Malaysia is described with molecular data. The new species differs from other species of the genus by the morphology of the largest clamp, the presence of a penis gun-associated needle, the unarmed genital atrium size, and the presence of two independent vaginal tubes. Previous records of Kannaphallus species were compiled, and four nominal species including one species incertae sedis (K. virilis Unnithan, 1957; K. lateriporis Mamaev, 1988; K. leptosomus n. sp.; and K. mochimae Fuentes Zambrano, 1998 incertae sedis) and two undescribed species recorded as invalid names were listed. Cemocotylelloides carangis Ramalingam, 1969 was considered a junior objective synonym of K. univaginalis Ramalingam, 1960; this species was treated as Cemocotylelloides univaginalis n. comb. In addition, Unnithan's materials including type specimens of K. virilis could not be found in specimen repositories in India, and it appears that the specimens were probably not deposited in any institution or have been subsequently lost. Based on the phylogenetic analysis of 28S rDNA sequences, Heteraxinidae was broadly divided into two clades, and Heteraxininae and Cemocotylinae were shown as polyphyletic groups, respectively.

Abstract
Redescription is given of heteraxinid monogeneans Zeuxapta seriolae (Meserve, 1938), type species of the genus, and Zeuxapta australica Lebedev, 1968 (formerly Z. seriolae australica). Type specimens of Z. seriolae from Seriola dorsalis from Galápagos Islands were differentiated from Z. australica specimens collected by Lebedev from Seriola glandis (now Seriola lalandi) from Tasman Sea, the type locality, by the shape of the vagina, which consisted of the transversely oval central body and horizontally extended paired tubes in the former, and the transversely oval central body and short, obliquely posteriad paired extensions in the latter. Zeuxapta japonica (Yamaguti, 1940) and Zeuxapta kahala (Yamaguti, 1968) were synonymized with Z. seriolae. Hitherto undescribed Zeuxapta specimens were also examined; those from Seriola aureovittata from Japan and China, and specimens from Seriola dumerili from Japan and Spain were identified as Z. seriolae, while those from Seriola lalandi from Chile and New Zealand were identified as Z. australica. Specimens from S. lalandi (as Seriola glandis) from Heron Island, Australia described by Rohde in 1978 as Z. seriolae consisted of Z. seriolae and Z. australica.

Bouguerche C, Tazerouti F, Justine JL. Four polyopisthocotyleans (Platyhelminthes: Monogenea) from carangid fishes in the Mediterranean, off the Algerian coasts. CURRENT RESEARCH IN PARASITOLOGY & VECTOR-BORNE DISEASES 2021; 1:100026.

Abstract
Four polyopisthocotyleans were collected from the gill filaments of carangids from off the Algerian coast, southern Mediterranean. Specimens of Gastrocotyle trachuri van Beneden & Hesse, 1863 (Gastrocotylidae) and Cemocotyle cf. trachuri Dillon & Hargis, 1965 (Heteraxinidae) from the Mediterranean horse mackerel Trachurus mediterraneus (Steindachner), Zeuxapta seriolae (Meserve, 1938) (Heteraxinidae) from the greater amberjack Seriola dumerili (Risso) and Pyragraphorus hollisae Euzet & Ktari, 1970 (Pyragraphoridae) from the pompano Trachinotus ovatus (Linnaeus) are redescribed based on newly collected specimens. Their taxonomically important morphological features (male copulatory organ and clamp sclerites) are described and illustrated, and the morphometric variation between Mediterranean and oceanic specimens is highlighted. Careful examination of the specimens of Cemocotyle Sproston, 1946 from the Mediterranean revealed that they exhibited unusual features compared with Cemocotyle trachuri Dillon & Hargis, 1965 from the Pacific, mainly the absence of the terminal lappet, thus questioning previous records of this species in the Mediterranean. New geographical locality records are provided for Z. seriolae and P. hollisae. The presence of C. cf. trachuri and Z. seriolae in the Mediterranean is noteworthy as these monogeneans were initially described in the Pacific Ocean. This study extends the geographical range of Z. seriolae to the southern Mediterranean.

Soler-Jiménez LC, Hernández-Mena DI, Centeno-Chalé OA, Vidal-Martínez VM. A new species of Neoheterobothrium Price, 1943 (Monogenea, Diclidophoridae) from Syacium papillosum (Linnaeus) (Pleuronectiformes, Paralichthyidae) in the Yucatan Shelf, with notes on the validity of the subfamilies in the Diclidophoridae. Parasitol Res 2021; 120:887-897.

Abstract
Neoheterobothrium papillosum n. sp. (Monogenea: Diclidophoridae) is described based on specimens collected from the gills of the dusky flounder Syacium papillosum (Linnaeus) (Paralichthyidae) in the Yucatan Shelf. The new species can be differentiated from other congeneric species by the following characteristics: (1) number of hooks in the genital atrium (8 hooks), (2) number of testes (20-34), (3) pharynx size, (4) peduncle length, and (5) egg size. Neoheterobothrium papillosum n. sp. resembles Neoheterobothrium syacii; however, detailed morphological analysis allowed for their separation into two different species. Sequences of the nuclear ribosomal DNA partial 28S and ITS1 were obtained and compared with available sequences of other species and genera of the family Diclidophoridae from GenBank. A phylogenetic analysis was conducted, including 33 sequences, 18 of which represented 17 species and 11 genera of the family Diclidophoridae. The phylogenetic tree showed that Diclidophoridae is a monophyletic family and species of Diclidophora were grouped as the sister group of Neoheterobothrium papillosum n. sp. Our phylogenetic analyses were consistent with Mamaev's hypothesis, who divided Diclidophoridae into Diclidophorinae and Choricotylinae and concluded that Neoheterobothrium was a genus belonging to Diclidophorinae.
