Geographic ranges and the hypothesis of the dispersal of the fishes of superfamily Congiopodoidea (Pisces: Scorpaenoidei) with the Antarctic Circumpolar Current

The most probable habitat of the ancestor superfamily Congiopodoidea Gill, 1889 is area modern Malay Archipelago and Australia; paths further distribution as well places origin taxa different ranks within are shown here based on morphological data. dispersal likely occurred via cold Antarctic Circumpolar Current, while members sister clade, family Synanceiidae Swainson, 1839, occupied new habitats primarily in a northerly direction. Fishes both families (Congiopodidae Zanclorhynchidae Andriashev, 1993) only eastward Australia, thus Zanclorhynchus spinifer heracleus Zhukov et Balushkin, 2018 appeared at Ridge Hercules Pacific Sector Southern Ocean after ancestral forms had overcome more than round-the-world migration. Six species genus Congiopodus Perry, 1811 have pairwise sympatric ranges. They apparently originated shelves Australia – C. leucopaecilus (Richardson, 1846), coriaceus Paulin Moreland, 1979, southern South America peruvianus (Cuvier, 1829), kieneri (Sauvage, 1878), torvus (Gronow, 1772) (Smith, 1839); moreover, last two migrated to point African continent. In Zanclorhynchidae, monotypic Alertichthys 1960 remained close place radiation superfamily; its range covers seamounts shelfs islands south New Zealand. path second this family, Günther, 1880 was much longer. waters part America, from form Prince Edward Islands Indian sector Ocean, where it differentiated into Z. chereshnevi Balushkin Zhukov, 2016. continued occupy eastern dividing four subspecies: armatus 2019, 1880, macquariensis heracleus. hypothesis about possibility with Current dispersive agent confirmed by data, when sequence occupation considered through degree relatedness fish inhabiting them.
