Gomon, M.F., Struthers, C.D. and Kemp, J. 2021. A review of the Australasian genus Pseudophycis (Gadiformes: Moridae), redescribing its four species and resurrecting the name Physiculus palmatus Klunzinger, 1872, for the Australian Red Cod. Memoirs of Museum Victoria 80: 103–143. The commercially fished Red Cod Pseudophycis bachus Forster in Bloch and Schneider, 1801, is shown on the basis of both morphological and genetic evidence to be confined to New Zealand waters. The separation of the closely related but distinct Australian cognate brings the number of species in the Australasian genus Pseudophycis to four. The name Physiculus palmatus Klunzinger, 1872, which was long thought to be a junior synonym of Pseudophycis barbata Günther, 1862, is demonstrated to have been originally proposed for the Australian endemic. Pseudophycis palmata (new combination) differs from P. bachus in having a prominent black blotch or spot basally on the pectoral fin that does not extend dorsally onto the body, in contrast to distinctly extending onto body, the second dorsal fin with 47–56 rather than 40–45 rays, the anal fin with 50–57 rather than 42–48 rays and the vertebral column with 47–50 rather than 44–46 total vertebrae. Diagnoses, colour descriptions, images and distributions for all four species and a key to members of the genus are provided.

Southwestern Indian Ocean

A new species of deepwater gurnard, Pterygotrigla (Otohime) madagascarensis sp. nov. is described, based on two specimens collected on the upper continental slope south of Madagascar, in the southwestern Indian Ocean. The new species belongs to the tropical Indo-Pacific subgenus Otohime in having a short rostral projection, short posttemporal spine, long opercular spine and no cleithral spine. It is most similar to P. (O.) multipunctata, and P. (O.) urashimai, in having no large blotch on the first dorsal fin, a jet-black blotch and no white ocellus on the inner pectoral-fin surface, with no scales on the breast and front of the pectoral-fin base. However, the new species differs from the latter two species by the combination of the following characters: first dorsal-fin spines 7, second dorsal-fin rays 12, dusky rays on the inner pectoral-fin surface, one row of blackish botches on second dorsal fin, and no papillae on the dorsal surface of oral cavity. A key is provided for the twelve Pterygotrigla species now in the subgenus Otohime.

Pimelodus carcio, originally described in 1822 by Francis Hamilton, has long been treated as a junior synonym of either Mystus tengara or M. vittatus. In this paper we revalidate and redescribe the species and diagnose it from other striped Mystus by the following combination of characters: small adult size, maturing at 44.0 mm standard length; adipose-fin base shorter than or equal to dorsal-fin base; pelvic fin reaching anal-fin origin; pectoral girdle with coracoid shield exposed ventro-laterally below pectoral fin; eyes rounded and large, dorsally orientated on head; vomerine tooth-patch interrupted at midline. The species is distributed in the Ganga-Brahmaputra drainage of northeast India and Bangladesh.

A new species of the uranoscopid genus Kathetostoma Günther, 1860, is described from New Zealand waters, where it is broadly sympatric with its sole local congener K. giganteum Haast, 1873. The new species is readily recognised by its broad, saddle-like dark bands that cross the body dorsally (versus bands absent or only faintly developed), rather robust and short body (vs slender and elongate), and fewer numbers of vertebrae (30–31 versus 33–34), dorsal fin rays (15–17 versus 17–19) and anal fin rays (15–16 versus 17–18). Although both species have extremely broad depth distributions, the new species appears to be restricted to less than about 500 m, with its greatest abundance at 100–300 m, while K. giganteum reaches over 1000 m, and has its greatest abundance at 200–400 m. A brief redescription of K giganteum is also provided. Kathetostoma fluviatilis Hutton, 1972, the oldest New Zealand name that applies to this genus, is regarded as a nomen dubium.

Three New Species

The presence of the sisorid catfish genus Erethistoides in Myanmar, represented by three new species, is recorded for thefirst time. This discovery from the Irrawaddy and Sittang river drainages from central Myanmar and the Ann ChaungRiver drainage in western Myanmar extends the documented range of the genus beyond the Ganges/Brahmaputra Riverbasin. Erethistoides longispinis is distinguished from congeners in having the following unique combination ofcharacters: length of the dorsal-fin spine 24–27% SL, length of the pectoral-fin spine 29–35% SL, and absence ofproximally-directed serrations on the anterior edge of the pectoral spine. Erethistoides luteolus differs from congeners inhaving the following combination of characters: yellow base color of the body, body with distinct bands, vertebrae 30,premaxillary tooth band partially exposed when the mouth is closed, length of the dorsal-fin spine 14–15% SL, length ofthe pectoral-fin spine 21–24% SL, absence of proximally-directed serrations on the anterior edge of the pectoral spine,length of the adipose-fin base 16–17% SL, length of the caudal peduncle 22–25% SL and depth of the caudal peduncle 6–7% SL. Erethistoides vesculus is distinguished from congeners in having the following combination of characters: creambase color of the body, body with distinct bands, vertebrae 30, premaxillary tooth band partially exposed when the mouthis closed, length of the dorsal-fin spine 15% SL, length of the pectoral-fin spine 22–23% SL, absence of proximally-directed serrations on the anterior edge of the pectoral spine, length of the adipose-fin base 14–15% SL, length of the caudal peduncle 19–21% SL and depth of the caudal peduncle 4–5% SL.

Osteological Characters

The structure of the pectoral fin, its girdle and osteological details of the axial skeleton and a skeleton of the caudal fin, including the structure of unpaired fins were studied in three species of three genera of the family Cottidae: the genus Cottus: European species C. koshewnikowi Gratzianov, 1907 and two species of Fareastern monotypic genera: Trachidermus fasciatus Heckel, 1837 and Mesocottus haitej (Dybowsky, 1869). The species well differ in structure of the pectoral girdles and pleural ribs. Mesocottus haitej is characterized by absence of the interradial and coracoid fenestrae and by considerable reduction of pleural ribs in the abdomen part of the vertebral column. Сottus koshewnikowi and T. fasciatus have backwardly directed pleural ribs (3 pairs of ribs in M. haitej). Trachidermus fasciatus is characterized with the most number of plesiomorphic features: the presence of branched rays in the pectoral fin, greater numbers of vertebrae, rays in the second dorsal, anal and pectoral fins, big anteanal distance and by number of preural vertebrae, supporting the procurrent rays. In C. koshewnikowi, the first dorsal fin occupies the most anterior position: aID 32.6–38.0% SL vs 35.7–38.7% SL in T. fasciatus and 36.4–40.8% SL in M. haitej.

The type-species of Hyphessobrycon is redescribed and its osteology provided. Hyphessobrycon compressus is distinguished from its congeners by the 41-48 (mode 45) scales in the longitudinal series; 7-9 (mode 9) scales rows between the dorsal-fin origin and the lateral line, and absence of predorsal scales. Additional useful characters include the lack of spots on the body, a dorsal fin with a black spot, and an anal fin with two large, conspicuous hooks, and several other small hooks. Hyphessobrycon milleri is proposed as a junior synonym of H. compressus . The osteology of H. compressus is discussed in detail together with comments about phylogenetic relationships of Hyphessobrycon sensu stricto .

Polypterus mokelembembe sp. n. is described from the central Congo River basin. It is distinguished from all other Polypterus species except P. retropinnis, P. teugelsi and P. palmas palmas by its high predorsal scale count (32–37 vs. 11–28). It differs from P. teugelsi by having 57– 60 lateral line scales (vs. 63–65), from P. palmas palmas by a single large black blotch on the pectoral-fin base (vs. numerous small spots on the posterior part of the base), and from P. retropinnis by having a wider first dorsal-fin spine (6.4–8.1 vs. 4.6–6.1 % of HL), a smaller internostril distance (11.6–13.7 vs 14.3–18.0 % of HL), and fewer pectoral-fin rays (23–29 vs. 30– 34). Inasmuch as the type series (comprising three specimens) of Polypterus retropinnis Vaillant, 1899 is of mixed composition, and includes two specimens of P. mokelembembe, a lectotype is designated for P. retropinnis and a rediagnosis for that species is provided.

Abstract Sucker barb fish is one of the potential of fish resources in Tasik river. This study aimed to determine the morphometric and meristic characteristics of the growth of sucker barb fish in the Tasik River. The method used in this study is a survey method using the fishing net and gillnet with mesh size 1,5 inches. The nets are placed in the afternoon, then lifted in the morning. This is done 3 times with a span of 2 weeks in the three research stations. The number of samples collected were 135 fish. The morphometric characteristics of sucker barb fish are bodyweight (BT) ranging from 9-85 g, total length (PT) ranging from 100-230 mm, standard length (PS) ranging from 75-176 mm, head length (PK) of 20-42 mm, snout length (PM) of 30 mm, the height of dorsal fin (TSP) of 40 mm, length of the base of dorsal fin (PPSP) of 15-30 mm, eye diameter (DM) of 10 mm, caudal peduncle (TBE) of 8-22 mm, body height (TB) of 17-40 mm, pectoral fin length (PSD) of 30 mm and pelvic fin length (PSP) of 25 mm. Meristic characteristics are the characteristics of counting the scales and fins of sucker barb fish. The number of scales in the lateral lines (LL) is 35-38, the body coiled scales (SMB) are 6, the scales around the pectoral fin (PF) P 10-14, anal fin (AF) A 8 and caudal fin (CF) C 18. The growth pattern of sucker barb fish in the Tasik River is allometric negative

A new species of jawfish, Opistognathus ocellicaudatus, is described based on a single specimen collected at 67 m depth in Sagami Bay (near the mouth of Tokyo Bay), Honshu Island, Japan. The new species can be separated from all other Indo-West Pacific jawfish species in having 3 longitudinal dark brown stripes on the body, a large dark whitish-rimmed ocellus on the caudal fin, a small black blotch on the opercular flap, the dorsal fin with 11 spines and 11 soft rays, the anal fin with 2 spines and 11 soft rays, 21 pectoral-fin soft rays, 26 vertebrae, 42 oblique scale rows, and 2 supraneurals. The holotype is a female containing mature eggs, suggesting summer spawning. The type locality was close to the northern distributional limit of Opistognathidae in the Indo-West Pacific.
