The new species Tosanoides annepatrice sp. n. is described from four specimens collected at depths of 115–148 m near Palau and Pohnpei in Micronesia. It differs from the other three species of this genus in life color and in certain morphological characters, such as body depth, snout length, anterior three dorsal-fin spine lengths, caudal-fin length, and other characters. There are also genetic differences from the other four species of Tosanoides (d ≈ 0.04–0.12 in mtDNA cytochrome oxidase I). This species is presently known only from Palau and Pohnpei within Micronesia, but it likely occurs elsewhere throughout the tropical western Pacific.


closed-circuit rebreather, coral-reef twilight zone, mesophotic coral ecosystems, Micronesia


The authors have explored mesophotic coral ecosystems (MCEs; coral-reef habitat at depths of 30–150 m; also referred to as the “coral-reef twilight zone”) throughout Micronesia for decades, and have utilized advanced mixed-gas closed-circuit rebreather diving operations since 1997, which has led to the discovery of dozens of new species of fishes (Pyle 1996a, 1996b, 2000, Pyle and Copus in press). One such new species was first discovered in 2007 during an expedition to Micronesia to film the BBC documentary Expedition Pacific Abyss (British Broadcasting Corporation 2007), when the second author collected a specimen of Tosanoides Kamohara, 1953 at a depth of 115 m off Ngaruangl Atoll, Kayangel State, Republic of Palau. Although the specimen differed substantially in color from the other two species of the genus known at the time, additional specimens were needed to ensure it was a distinct and previously undescribed species. During an expedition to Pohnpei, Federated States of Micronesia in 2015 (Rowley et al. in press), the first two authors observed additional individuals of this Tosanoides at a depth of 148 m off the west end of Ahnd (Ant) Atoll, outside the entrance to a small cave along a vertical reef drop-off. During a subsequent expedition to Pohnpei in 2016, the second author managed to collect one large adult male and two juvenile specimens.

The specimens represent an undescribed species of the serranid subfamily Anthiadinae Poey 1861 (commonly spelled Anthiinae), within the genus Tosanoides. The genus currently includes four nominal species: Tosanoides filamentosus Kamohara, 1953 (type species), T. flavofasciatus Katayama & Masuda, 1980, T. obama Pyle, Greene & Kosaki, 2016, and T. aphrodite Pinheiro, Rocha & Rocha, 2018. Herein we describe the fourth member of the genus, Tosanoides annepatrice, based on morphologic and genetic differences compared with the other known species. In addition, the species currently referred to as Pseudanthias fucinus (Randall & Ralston, 1985) from the Hawaiian Islands is likely a member of the genus Tosanoides, and is similar in many respects to T. aphrodite.

At least two other undescribed species of this genus have been reported; one from the Coral Sea (Gerald R. Allen pers. comm.) and one from Rapa Nui (Easter Island) (Easton et al. 2017).

Materials and methods

Specimens were collected with hand nets during deep dives using mixed-gas, closed-circuit rebreathers, and brought to the surface alive with the aid of a hypodermic needle to vent gas from the swim bladders. Methods for counts and measurements follow those described in Pyle et al. (2016). Gender of adult specimens based on examination of gonads. Description template and wording follow Pyle et al. (2016), modified from Katayama and Masuda (1980) for consistency.

The holotype has been deposited at the Bernice Pauahi Bishop Museum fish collection, Honolulu (BPBM), and paratypes have been deposited at the U.S. National Museum of Natural History, Washington, D.C. (USNM) and California Academy of Sciences, San Francisco (CAS).

Fresh tissue samples were obtained from the holotype and paratypes. DNA barcodes (cytochrome c oxidase I; COI) were sequenced following the protocol described in Copus et al. (2015). Barcode of Life Database (BOLD) identifiers for DNA sequences are presented along with museum catalog numbers for type material and non-type specimens. A neighbor-joining tree building method was used to reconstruct the phylogenetic tree using Geneious v.6.2 (Kearse et al. 2012) under the HKY model of sequence evolution, with a random seed of 920,582, 100,000 bootstrap replicates, and 50% support threshold. Estimates of genetic differences (d) were also calculated in Geneious.

Tosanoides annepatrice is known on the basis of four specimens, one (the holotype) collected at a depth of 115 m in Palau, and three paratypes collected at a depth of 148 m near Pohnpei. Additional individuals have been observed at depths of ~120–150 m at Pohnpei. The species likely occurs at similar depths throughout much of Micronesia, and perhaps more broadly within the tropical western Pacific; but more exploration of habitat at appropriate depths throughout this region is necessary to determine its complete geographic range.

Habitat and Ecology

Tosanoides annepatrice has been observed and collected along steep limestone coral-reef drop-offs at depths from 115–150 m. The paratypes were collected along a small rocky crevice near the entrance to a cave, but other individuals have been seen in similar habitats not in association with caves. Most individuals of this species have been observed in groups consisting of one apparent male and several apparent females and juveniles.


We name this species annepatrice (a noun in apposition) in honor of Anne Patrice Greene, mother of Brian D. Greene who collected all known specimens of this new species, in recognition of the support and encouragement she has consistently provided to Brian’s exploration of the deep coral reefs of Micronesia.

Morphological comparisons

The morphology of this species is consistent with the diagnosis for the genus Tosanoides as presented by Katayama & Masuda 1980. Compared with Pseudanthias Bleeker, 1871 (the only other genus it resembles), T. annepatrice shares with the other three species of Tosanoides fewer pored lateral-line scales (30–34, compared with 35–52) number of anal soft rays (8, compared with 6–7), and unbranched pectoral fin rays. Morphological comparisons with other species of Tosanoides are as follows, and only compare values for adult specimens of T. annepatrice.

Tosanoides annepatrice is more similar morphologically to T. filamentosus than to T. obama (Figure 6) or T. flavofasciatus (Figure 7), primarily on the basis of proportional dorsal-fin spine lengths (first dorsal spine the longest, compared with third or fourth dorsal spine the longest in flavofasciatus), body depth (2.6 in SL, compared with 2.5 for T. flavofasciatus and 2.8–2.9 for T. obama), and snout length (4.3–5.7 in head, compared with 2.3–2.9 for T. flavofasciatus and 6.4 – 7.1 for T. obama). It is also similar to T. obama in number of pored lateral line scales (33–34, compared with 30–32 for T. flavofasciatus and 35 for T. filamentosus) and number of pectoral-fin rays (14, compared with 13 for T. flavofasciatus and T. filamentosus). The dorsal-fin profile of T. annepatrice differs considerably from both T. flavofasciatus and T. obama, in having much longer spines (2.6 in head, compared with 2.7–3.0). Another unique feature of T. annepatrice is that in both adult specimens, the second dorsal-fin spine is immediately adjacent to the first spine. This feature is not evident in the two immature paratypes, so it is uncertain whether this character is typical of all adults, only adult males, or is peculiar to these two specimens.

All four species of Tosanoides can also be easily distinguished from each other on the basis of life color.

Genetic comparisons

Vertebrate mtDNA barcode (cytochrome oxidase I) sequences obtained from T. annepatrice reveal genetic differences of 3.9–4.0% when compared with T. filamentosus, and 9.9–12% pairwise genetic distances when compared with the other two described species of Tosanoides (Figure 8). The difference from T. filamentosus is consistent with many species-level divergences in other fish taxa (e.g., Johns and Avise 1998, Bellwood et al. 2004, Fessler and Westneat 2007, Randall and Rocha 2009, Rocha 2004, Rocha et al. 2008, Pyle and Kosaki 2016), and considerably more so for the other two species. Based on a preliminary genetic analysis, all four species of Tosanoides have closer genetic affinities to each other than to representatives of other Indo-Pacific anthiadine genera analyzed (Figure 8). On this basis, as well as morphological comparisons, we are confident in assigning the new species to the genus Tosanoides until a more exhaustive investigation of phylogenetic relationships among the species in this subfamily is completed.

Tosanoides annepatrice is yet another example of several new fish species that have been discovered on deep coral reefs over the past several decades, mostly involving the use of modern mixed-gas closed-circuit rebreather diving technology (Pyle 1996a, 1996b, 2000, in press). In recent years there has been increased attention focused on mesophotic coral ecosystems (MCEs), coral-reef habitat at depths of approximately 30–150 m in tropical regions worldwide (Hinderstein et al. 2010, Baker et al. 2016, Loya et al. in press). Many more new species of fishes and other reef-associated marine organisms are likely to be discovered as a result of continued exploratory work in this poorly documented environment (Pyle and Copus in press, Pyle et al. in press), and particularly throughout Micronesia (Rowley et al. in press).


We are grateful to Sonia J. Rowley, who led a series of deep-diving expeditions to Pohnpei (including the 2016 expedition on which the type specimens of T. annepatrice were collected). We are also grateful to Luiz A. Rocha for providing aquarium photos of this species, including those represented here as Figure 3 and Figure 5. Ross Langston and Sam Geiling of Windward Community College in Hawai‘i provided assistance in obtaining x-radiographs. Collection of the holotype of T. annepatrice was funded by the British Broadcasting Corporation (BBC), and funding for several expeditions to Pohnpei was provided by the Association for Marine Exploration and grants to Sonia J. Rowley from the Systematic Research Fund (SRF; supported by the Linnaean Society of London and the Systematics Association), Ocean First Education (formerly Ocean Classrooms), and the Edmondson Foundation through Bishop Museum. Additional financial support for the 2016 expedition to Pohnpei was provided by the California Academy of Sciences. Valuable Logistical support in Pohnpei was provided by Walter Wilbur and family at the Nihco Marine Park, and the Conservation Society of Pohnpei (CSP). Radiographs were provided by Katherine “Sam” Geiling, RVT, Kathleen Baxter, RVT, and the Windward Community College Vet Tech Class of 2019. Additional funding for this work was provided by NSF OCE-1558852.
