“…Bray et al (2014) also included Biospeedotrema (Bray, Waeschenbach, Dyal, Littlewood & Morand, 2014) in this subfamily, comprising three species, B. biospeedoi (Bray, Waeschenbach, Dyal, Littlewood & Morand, 2014), B. jolliveti (Bray, Waeschenbach, Dyal, Littlewood & Morand, 2014), and B. parajolliveti (Bray, Waeschenbach, Dyal, Littlewood & Morand, 2014). However, the results of phylogenetic analyses based on 28S rRNA gene, by Shedko, Sokolov, and Atopkin (2015), Sokolov and Shchenkov (2017), Sokolov, Lebedeva, Gordeev, and Khasanov (2019), and Pérez‐Ponce de León and Hernández‐Mena (2019) do not support including Biospeedotrema spp. in the family Opecoelidae.…”

A new species, Caudotestis dobrovolski n. sp., is described from Liparis sp. (Scorpaeniformes: Liparidae) and Eumicrotremus fedorovi Mandrytsa, 1991 (Scorpaeniformes: Cyclopteridae), caught in the Simushir Island area of the North Pacific. This species differs from six previously known congeners by the following combination of features: the excretory vesicle reaches to the anterior edge of the ventral sucker, uterus pretesticular, genital pore prebifurcal and median, and testes entire or with irregular outline, occasionally distinctly lobate. Phylogenetic analysis of 28S rRNA gene partial sequences suggests a sister position of Caudotestis Issaitschikov, 1928 to the genus Biospeedotrema Bray, Waeschenbach, Dyal, Littlewood, & Morand, 2014, and unites C. dobrovolski n. sp. + Biospeedotrema spp. with Zdzitowieckitrema incognitum Sokolov, Lebedeva, Gordeev, & Khasanov, 2019. The phylogenetic relationship of Biospeedotrema and Zdzitowieckitrema Sokolov, Lebedeva, Gordeev, & Khasanov, 2019 with respect to the Opecoelidae is currently uncertain and, within the Xiphidiata, these genera are currently without adequate familial classification. However, Caudotestis belongs to the Stenakrinae, a subfamily within the Opecoelidae. Three other stenakrine species—Holsworthotrema enboubalichthys Martin, Huston, Cutmore, & Cribb, 2018, Holsworthotrema chaoderma Martin, Huston, Cutmore, & Cribb, 2018, and Scorpidotrema longistipes Aken’Ova & Cribb, 2003—are integrated into a large clade of the opecoelid trematodes. Therefore, the Stenakrinae is apparently polyphyletic.

“…When the genus Biospeedotrema Bray, Waeschenbach, Dyal, Littlewood & Morand (2014) was erected the number of opecoelid sequences available was limited and the genus was considered, based on its basally derived position in the phylogenetic tree and the morphology of the ‘suboptimally preserved’ specimens, to belong to the opecoelid subfamily Stenakrinae. This position was questioned by Shedko et al (2015) and later studies by Sokolov et al (2019b ; 2019c) have shown that it is sister to Caudotestis dobrovolski Sokolov, Lebedev. Shchenkov & Gordeev, 2019 forming a clade which, with Zdzitowieckitrema incognitum Sokolov, Lebedeva, Gordeev & Khasanov, 2019 , may be a sister clade to the Opecoeloidea, although resolution of this relationship is poor.…”

Digenean parasites of deep-sea teleosts: A progress report

The developments in the study of digeneans of deep-sea fish in the 21st Century are documented and discussed. Most recent work has been on the bathyal fauna (i.e. 1,000m-2,999 m depth), with virtually nothing on the abyssal fauna (i.e. deeper than 3,000 m). The one study on hydrothermal vent digeneans has indicated that these regions probably harbour a distinctive fauna. The demarcation of the deep-sea fauna is blurred at the poles, where the cold-adapted fauna appears similar to the shallower bathyal fauna. The abyssal fauna, however, appears distinct, possibly due to adaptations to variable or ultra-high pressures. The digenean fauna of bathypelagic fishes is depauperate. Recent phylogenetic studies reinforce the view that the typical deep-sea fauna has radiated in the deep-sea. Encroachment into the deep from shallow water is relatively rare. Overall, the digenean fauna in the deep-sea is distinctly less diverse that the equivalent fauna in shallow waters. A major conclusion is that our understanding of the deep-sea digenean fauna is poor, and that much further work over a much wider area is needed.
