“…The apparently strict host specificity for lethrinid fishes is perhaps the most intriguing aspect of the nature of the Pseudoplagioporinae. The only other opecoelid subfamily with comparable specificity among its constituent taxa is the Polypipapiliotrematinae, a clade of specialized species, represented by a single genus, which are known almost entirely from corallivorous butterflyfishes (Chaetodontidae) (Martin, Sasal, et al., ). However, in that case, the pattern of strict specificity for the definitive hosts is clearly linked to the exploitation of a novel second intermediate host group, scleractinian corals.…”

The Pseudoplagioporinae n. subf. (Opecoelidae) is proposed for species of Pseudoplagioporus Yamaguti, 1938, Fairfaxia Cribb, 1989, and Shimazuia Cribb, 2005, a small group of relatively distinctive, Indo‐West Pacific taxa reliably known almost entirely from emperor fishes (Perciformes: Lethrinidae). These taxa were previously recognized in the Plagioporinae Manter, 1947, but that subfamily has recently been restricted to a clade of Holarctic, freshwater taxa, whereas analyses of new genetic data find the pseudoplagioporines to form a distinct clade among a larger assemblage of marine taxa. New material was sourced from fishes collected mainly in Queensland waters, Australia, but with some specimens from off Western Australia, the Northern Territory, and Japan. Orthodena tropica Durio & Manter, 1968 is transferred to Pseudoplagioporus as P. tropicus (Durio & Manter, 1968) n. comb., and Orthodena Durio & Manter, 1968 thus becomes a synonym of that genus. Three new species of Pseudoplagioporus are proposed. One, P. mediocris n. sp., like other species of Pseudoplagioporus, occurs in several species of Lethrinus. The other two new species, P. labiatus n. sp. and P. roseovulatus n. sp., apparently do not infect species of Lethrinus and were instead found only in the Bigeye emperor Monotaxis grandoculis (Forsskål) and the Redfin emperor M. heterodon (Bleeker), respectively. New host‐locality combinations and the first genetic data, for the ribosomal ITS2 DNA region, and the 28S rRNA, 18S rRNA, and cox1 mtDNA genes, are reported for Pseudoplagioporus lethrini Yamaguti, 1938, P. interruptus Durio & Manter, 1968, P. tropicus, Fairfaxia lethrini Cribb, 1989, Fairfaxia cribbi Hassanine & Gibson, 2005, and Shimazuia lethrini (Yamaguti, 1938) Cribb, 2005.

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.

However, the fact that butterflyfishes remove limited coral tissue without exposing the underlying skeleton may make them unlikely candidates to transmit microbes among individual corals [16].…”

Parrotfish predation drives distinct microbial communities in reef-building corals

et al. 2020

Background: Coral-associated microbial communities are sensitive to multiple environmental and biotic stressors that can lead to dysbiosis and mortality. Although the processes contributing to these microbial shifts remain inadequately understood, a number of potential mechanisms have been identified. For example, predation by various corallivore species, including ecologically-important taxa such as parrotfishes, may disrupt coral microbiomes via bite-induced transmission and/or enrichment of potentially opportunistic bacteria. Here, we used a combination of mesocosm experiments and field-based observations to investigate whether parrotfish corallivory can alter coral microbial assemblages directly and to identify the potentially relevant pathways (e.g. direct transmission) that may contribute to these changes.Results: Our mesocosm experiment demonstrated that predation by the parrotfish Chlorurus spilurus on Porites lobata corals resulted in a 2-4x increase in bacterial alpha diversity of the coral microbiome and a shift in bacterial community composition after 48 h. These changes corresponded with greater abundance of both potentially beneficial (i.e. Oceanospirillum) and opportunistic bacteria (i.e. Flammeovirgaceae, Rhodobacteraceae) in predated compared to mechanically wounded corals. Importantly, many of these taxa were detectable in C. spilurus mouths, but not in corals prior to predation. When we sampled bitten and unbitten corals in the field, corals bitten by parrotfishes exhibited 3x greater microbial richness and a shift in community composition towards greater abundance of both potential beneficial symbionts (i.e. Ruegeria) and bacterial opportunists (i.e. Rhodospiralles, Glaciecola). Moreover, we observed 4x greater community variability in naturally bitten vs. unbitten corals, a potential indicator of dysbiosis. Interestingly, some of the microbial taxa detected in naturally bitten corals, but not unbitten colonies, were also detected in parrotfish mouths. Conclusions: Our findings suggest that parrotfish corallivory may represent an unrecognized route of bacterial transmission and/or enrichment of rare and distinct bacterial taxa, both of which could impact coral microbiomes and health. More broadly, we highlight how underappreciated pathways, such as corallivory, may contribute to dysbiosis within reef corals, which will be critical for understanding and predicting coral disease dynamics as reefs further degrade.
