  DOI: 10.3897/zookeys.680.12727 

Abstract

This communication describes a new octocoral, Altumia delicata gen. n. & sp. n. (Octocorallia: Clavulariidae), from mesophotic reefs of Eilat (northern Gulf of Aqaba, Red Sea). This species lives on dead antipatharian colonies and on artificial substrates. It has been recorded from deeper than 60 m down to 140 m and is thus considered to be a lower mesophotic octocoral. It has no sclerites and features no symbiotic zooxanthellae. The new genus is compared to other known sclerite-free octocorals. Molecular phylogenetic analyses place it in a clade with members of families Clavulariidae and Acanthoaxiidae, and for now we assign it to the former, based on colony morphology. The polyphyletic family Clavulariidae is, however, in need of a thorough revision once the morphological distinctions among its phylogenetically distinct clades are better understood.

Keywords: Octocorallia, new genus, taxonomy, mesophotic coral ecosystem, Eilat, Red Sea

Family Clavulariidae Hickson, 1894

Subfamily Clavulariinae Roxas, 1933

Altumia gen. n.

Diagnosis: Clavulariinae with a thin and soft encrusting base, sometimes resembling a short stolon. Polyps erect when expanded, separate from each other; the stolon may feature a few polyps, occasionally only one. Polyps fully retractile into base of the colony, forming low truncated dome-shaped mounds. No sclerites in any part of the colony. Colonies lack symbiotic algae (zooxanthellae). Type species: Altumia delicata sp. n. by original designation and monotypy.

Etymology: The generic name is derived from the Latin ‘altum’, deep, referring to the habitat of the new genus at MCE depths and beyond. Gender female.

 Holotype: ZMTAU CO 37427, Israel, Gulf of Aqaba, Eilat, 29°30'38.31"N, 34°55'59.30"E, 132 m, 30 May 2016, collected by ROV, coll. M. Weis; paratype: ZMTAU CO 37495, Israel, Gulf of Aqaba, Eilat, 29°30'37.29"N, 34°55'59.28"E, 118 m, 8 March 2017, collected by ROV, coll. M. Weis

Diagnosis: The ethanol-preserved holotype is comprised of thin patches of short stolon-like crusts growing over the dead branch of a black coral (Antipatharia) (Figure 2A), almost invisible to the naked eye. The milky-white, thin (<0.5 mm) crusts are a few mm long (Figure 2B), very soft, almost slime-like. Polyps completely retracted and practically invisible in the preserved colonies. No sclerites observed in any part of the colony.

Intraspecific variability: There are no differences between the holotype and the paratype except for the size of the colonies.

Etymology: The species name is formed from the Latin ‘delicata’, delicate, referring to the fine texture of the colonies and their polyps. Gender female.

[Ichthyology • 2017] Palatogobius incendius • A New Mesophotic Goby (Teleostei: Gobiidae) from the Caribbean, and the First Record of Invasive Lionfish Preying on Undescribed Biodiversity ---ScRaBBlE

Palatogobius incendius 

Tornabene, Robertson & Baldwin, 2017

DOI:  10.1371/journal.pone.0177179

Abstract

A new species of deep-reef fish in the goby genus Palatogobius is described from recent submersible collections off Curaçao and Dominica. Video footage of schools of this species reveal predation by the invasive Indo-Pacific lionfish (Pterois spp.), the first record of undescribed fauna potentially being eaten by lionfish outside of its native range. We present molecular phylogenetic data for all valid species of Palatogobius and related genera, as well as a taxonomic key to the species of Palatogobius and a generic key to Palatogobius and related genera in the western Atlantic. Lastly, we discuss ecological and behavioral aspects of some deep-reef fishes in light of potential threats from invasive lionfish.

Palatogobius incendius Tornabene, D. Ross Robertson & Baldwin, sp. nov.

Diagnosis: Side of body with yellow/orange stripe along lateral midline, stripe continuing onto and extending entire length of caudal fin; second dorsal fin I,14–16; anal fin I,14–17; pectoral fin 18–20; no teeth on vomer; body scales absent except for occasionally 2 to 3 cycloid scales on base of caudal fin; interorbital pore C absent; interorbital pores D paired; eye diameter 7.0–9.0% SL.

Etymology: The specific epithet incendius is an adjective formed from the Latin root incendium meaning ‘fire.’ The scientific and proposed common names refer to the bright orange, yellow and reddish-pink coloration on the body, head and fins.

Fig 6. School of Palatogobius incendius at type locality, sta. CURASUB15-30, 152 m depth, Curacao. 

Habitat and distribution: Palatogobius incendius has been collected on deep reefs from Curacao (119–128 m) and Dominica (88–168 m) and observed off Roatan, Honduras (94–201 m). The species occurs exclusively in hovering schools ranging in size from as small as 5 to 10 individuals (rare) to 50->200 individuals (Fig 6). Schools are most frequently found at the top or bottom of vertical walls off Curaçao and Dominica, but off Roatan we observed more than a dozen schools of P. incendius collectively comprising as many as 1000 individuals over a long, gradually inclining stretch of sand and small rocks from ~150–170 m depth. Over this stretch, P. incendius co-occurred with many individuals of P. grandoculus, which were closer to the bottom rather than hovering well off the bottom like P. incendius. Schools of P. incendius generally comprise individuals at multiple life stages, ranging from moderately developed larvae (~9 mm SL) to adults. Off Dominica we also observed larger swarms of minuscule fish (~5 mm TL) that could possibly be very recently recruited P. incendius larvae, given their size, abundance and depth range. Individuals in these swarms were too small to be captured, and were observed traveling only a few cm off the bottom rather than hovering in a cloud well above the substrate. These schools of post-larvae were 1–2 m wide and up to 5 m long, and moved steadily upslope at approximately 0.15 m/s, navigating laterally around obstacles in a fashion superficially similar to a wide chain of marching army ants.

[Cnidaria • 2017] Sinularia mesophotica • Search for Mesophotic Octocorals (Cnidaria, Anthozoa) and Their Phylogeny. II. A New Zooxanthellate Species from Eilat, northern Red Sea ---ScRaBBlE

Sinularia mesophotica 

Benayahu, McFadden, Shoham & van Ofwegen, 2017   

  DOI:  10.3897/zookeys.676.12751 

Abstract
An octocoral survey conducted in the mesophotic coral ecosystem (MCE) of Eilat (Gulf of Aqaba, northern Red Sea) yielded a new species of the speciose reef-dwelling genus Sinularia. It features encrusting colony morphology with a thin, funnel-shaped polypary. Sinularia mesophotica sp. n. (family Alcyoniidae) is described and compared to the other congeners with similar morphology. Both the morphological and molecular examination justified the establishment of the new species, also assigning it to a new genetic clade within Sinularia. The results highlight its unique phylogenetic position within the genus, and this is the first described species of a mesophotic zooxanthellate octocoral.

Figure 1. Sinularia mesophotica sp. n.; A Holotype ZMTAU Co 37425 B paratypes ZMTAU Co 37492.

Scale bar: 1 cm (A also applies to B). 

Diagnosis: The holotype is part of an encrusting colony with a thin, funnel-shaped polypary, also featuring a curly margin (Fig. 1A). In a side-view its maximum dimensions are 5 × 2.5 cm. Polyps with tentacle rods and collaret sclerites (Fig. 2A–C). Tentacle rods up to 0.10 mm long (Fig. 2A). Collaret consists of almost straight spindles, up to 0.20 mm long (Fig. 2B), and shorter bent ones, up to 0.14 mm long (Fig. 2C). Surface layer of the polypary with clubs (Fig. 2D), some featuring a central wart, while in others it is less discernible, or even absent. Clubs vary from 0.10 mm long to 0.25 mm long, and a few with poorly developed heads attain 0.27 mm (Fig. 2E). Surface layer of the colony base contains clubs up to 0.22 mm; some similar to those of polypary, and others have wide heads (Fig. 3A). Polypary and base interior bear spindles, some branched, up to 3.2 mm long (Fig. 3B), with well-spaced simple tubercles (Fig. 3C).

Etymology: The new species name reflects its mesophotic habitat.

Figure 2. Live specimen of Roa rumsfeldi sp. n. photographed at the California Academy of Sciences’ Twilight Zone exhibit (photo LA Rocha).

DOI: 10.3897/zookeys.709.20404 

Abstract

A new species of the butterflyfish genus Roa is herein described from the Verde Island Passage in the Philippines, West Pacific Ocean. Roa rumsfeldi sp. n. was found on mesophotic coral ecosystems at Puerto Galera and Batangas, and sampled through technical mixed-gas rebreather diving at 100–130 m depth. This represents the fifth known species of Roa. The main differences between Roa rumsfeldi sp. n. and its congeners are the lower number of pored scales in the lateral line, longer snout, longer caudal peduncle, shorter caudal fin, pelvic fin color (dark first spine vs. white in all other Roa), and genetics (8.4% divergence from its closest relative Roa modesta in the mitochondrial COI gene). Roa spp. are usually seen in pairs, but the two specimens we collected were solitary individuals. We have kept one of the specimens alive in the California Academy of Sciences’ Twilight Zone exhibit for more than one year, where it thrives and is feeding on a variety of dried and fresh food.

Keywords: Coral triangle, deep reefs, new species, rebreather diving, reef fish

Roa rumsfeldi sp. n. 

Deep-blackfin butterflyfish

Diagnosis: Roa rumsfeldi sp. n. differs from all of its congeners by the smaller number of pored scales in the lateral line pored scales (27 versus 37-46 in other Roa), longer snout (35.9% in HL vs. 28.2–35.5%), shorter first dorsal ray (12% in SL vs. 16.6–26.6%), longer caudal peduncle (8.5% in SL vs. 4.2–8.2%), shorter caudal fin (15.9% in SL vs. 19.8–25.9%), and a dark brown pelvic-fin spine (white in all other known Roa species).

Etymology: We name Roa rumsfeldi to honor Donald Rumsfeld who immortalized the quote: “there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – the ones we don’t know we don’t know.” He said that when referring to the uncertainties of war, but we think it applies perfectly to the taxonomy of MCE species: We only realized this species was new after we took a good look at it here at the aquarium in San Francisco, so we think it’s a perfect example of an unknown unknown.

Distribution and habitat: Roa rumsfeldi sp. n. is only known to occur in the Verde Island Passage, central Philippines. It was found on MCEs of Puerto Galera, Oriental Mindoro, and Bauan, Batangas, between 100 and 130 m depth. However, the species likely has a wider distribution and remains undetected because of its preferred depth range. The ecosystems where it was found vary from sheltered rocky outcroppings heavily covered by fine sediment to areas exposed to strong currents. The ambient seawater temperature varied between 19 and 21°C during our dives, which were conducted in April-May over several years. Azooxanthellate gorgonians, black corals, and solitary stony corals are the most abundant benthic invertebrates in this habitat.

[Ichthyology • 2018] Tosanoides aphrodite • A New Species (Perciformes, Serranidae, Anthiadinae) from Mesophotic Coral Ecosystems of St. Paul’s Rocks, Mid Atlantic Ridge ---ScRaBBlE

 Tosanoides aphrodite

 Pinheiro, Rocha & Rocha, 2018

DOI: 10.3897/zookeys.786.27382 

Abstract

During a recent expedition to St. Paul’s Rocks, Atlantic Ocean, a distinctive and previously unknown species of Anthiadinae was collected at a depth of 120 m. A genetic analysis indicated the undescribed species is a member of the genus Tosanoides, which was only known to occur in the Pacific Ocean. This new taxon is distinguishable from all other Tosanoides species by the following combination of characters: soft dorsal fin rays 15–16; anal fin rays 9; ventral scale rows 9–10; last dorsal spine the longest (instead first through fourth). Here Tosanoides aphrodite sp. n. is described and illustrated, only known from St. Paul’s Rocks.

Keywords: Brazil, coral reefs, deep reefs, fish endemism, oceanic island, rebreather diving

Figure 3. Fresh specimens of Tosanoides aphrodite sp. n. collected in St. Paul’s Rocks, Brazil. A Male B Female. Photographs by LA Rocha. 

Tosanoides aphrodite sp. n.

Diagnosis: The new species differs from all other Anthiadinae by the following combination of characters: Dorsal-fin spines X; last dorsal spine the longest, 1.8–2.2 in head length; dorsal-fin rays 15–16; 7th dorsal ray the longest, 2.65–2.80 in head length; anal-fin rays 9; pored lateral-line scales 32–35; ventral scale rows 9–10; body slender and compressed, greatest depth 2.96–3.18 in SL, and the width 1.77–2.09 in depth. Our phylogenetic analysis shows the new species belongs to Tosanoides Kamohara 1953, from which it differs of the other known species by: a divergence of at least 12.35% at the cytochrome oxidase I gene, last dorsal spine the longest (instead first through fourth), fewer dorsal-fin rays (15–16 vs. 16–17), and more anal-fin rays (9 vs. 8 in the other Tosanoides).

....

Figure 4. Tosanoides aphrodite sp. n.  in its natural environment, photographed at a depth of 120 m in St. Paul’s Rocks, Brazil. Photograph by LA Rocha.

Etymology: The name “aphrodite” refers to the ancient Greek goddess of love and beauty. While we were collecting the Aphrodite anthias, a large Six-gill shark (Hexanchus griseus) came very close to both of us (HTP and LAR), but that didn’t divert our attention from the new exquisitely beautiful species, and we never even saw the shark (youtu.be/pSZrmoEwR0Q). The beauty of the Aphrodite anthias enchanted us during its discovery much like Aphrodite’s beauty enchanted ancient Greek gods.

Distribution and habitat: Tosanoides aphrodite is only known from Saint Paul’s Rocks, off Brazil. It was found on mesophotic coral ecosystems of the island, observed between 100 and 130 m depth while rebreather diving, and a single observation at 260 m depth, taken from a submersible dive. The species inhabits small crevices of complex rocky reefs (Figure 4). The ambient seawater temperature at the collecting depth (~ 120 m) varied between 13 and 15 °C during the two-week period we stayed in the area.

[Ichthyology • 2018] Tosanoides annepatrice • A New Basslet (Perciformes, Serranidae) from Deep Coral Reefs in Micronesia ---ScRaBBlE

Tosanoides annepatrice 

Pyle, Greene, Copus & Randall, 2018

 DOI:  10.3897/zookeys.786.28421 

Abstract
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.

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

Tosanoides annepatrice sp. n.

Diagnosis: A species of Tosanoides (sensu Katayama and Masuda 1980) distinguished by the following combination of characters: fourth or fifth dorsal spine the longest; dorsal-fin soft rays 16–17; anal-fin soft rays 8; pored lateral-line scales 33–34; head 2.3–2.9 in SL; body depth 2.6 in SL; color in life of males: head and body rose-pink, crossed by four bright yellow stripes, the third continuing as a bright red stripe with magenta edges along the middle of the body, becoming yellow centered on base of caudal fin; dorsal fin with a very broad middle yellow stripe with magenta margin; base of anal fin colored like body anteriorly, grading broadly to magenta posteriorly; pelvic fins yellow, except for magenta last two rays; eye magenta with an uneven ring of yellow around pupil; color of immature and presumed female yellow with irregular, near-vertical, wavy red lines following scale margins; anal fin magenta anteriorly, grading posteriorly to purple, with a greenish yellow streak; pelvic fins bright magenta.

Photographs by LA Rocha.

Distribution: 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.

Etymology: 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.

[Ichthyology • 2018] Plectranthias ahiahiata • A New Species of Perchlet (Serranidae, Anthiadinae) from A Mesophotic Ecosystem at Rapa Nui (Easter Island) ---ScRaBBlE

Plectranthias ahiahiata

Shepherd, Phelps, Pinheiro, Pérez-Matus & Rocha, 2018

DOI:  10.3897/zookeys.762.24618 

Abstract

A new species of the perchlet genus Plectranthias is herein described from a single specimen found at Rapa Nui (Easter Island) in the South Pacific. Plectranthias ahiahiata sp. n. was collected at a depth of 83 m in a mesophotic coral ecosystem at Rapa Nui. The main difference between Plectranthias ahiahiata and other members of the genus is higher fin-ray counts (X, 18 dorsal; 18 pectoral) and its distinctive coloration. Compared to the three other known eastern South Pacific species, P. ahiahiata has more dorsal-fin rays, more pectoral-fin rays, fewer tubed lateral-line scales, fewer gill rakers, a longer head relative to SL, a very short first dorsal spine relative to SL, and a short third anal spine relative to SL. Plectranthias ahiahiata is distinguished from western Pacific species, by having more dorsal- and pectoral-fin rays. The closest relative based on genetic divergence (with 12.3% uncorrected divergence in the mitochondrial COI gene) is Plectranthias winniensis, a widely distributed species, suggesting important links between Rapa Nui and western Pacific islands. This new species adds to the high endemism of the Rapa Nui ichthyofauna, and is further evidence of the importance of mesophotic reefs as unique communities.

Plectranthias ahiahiata sp. n.

  Sunset perchlet

Type locality: Hanga Piko, Rapa Nui (Easter Island), Chile.

  

Diagnosis: Plectranthias ahiahiata differs from all of its congeners by the following combination of characters: dorsal rays X, 18; pectoral rays 18; longest dorsal spine the fourth; LL continuous and complete with 31 tubed scales; circumpeduncular scales 16; head length 43.3% SL; first dorsal spine 4.5% SL; third anal spine 13.7% SL; gill rakers 6+11; and in coloration: overall orange-red in color, with predominantly yellow snout, dorsal, pelvic and anal fins, a brilliant red spot outlined in white on the caudal peduncle, and four white spots on each side, following the contour of the lateral line.

Etymology: Plectranthias ahiahiata is given a Rapa Nui name; the phrase ahiahi-ata means “the last moments of light before nightfall.” The species was given this name because the colors of the fish remind us of the beautiful Rapa Nui sunsets. To be treated as a noun in apposition.

Distribution and habitat: Plectranthias ahiahiata is currently only known to occur at Rapa Nui (Easter Island). This fish was collected with hand nets at a depth of 83 m in a rocky patch reef surrounded by a large sandy area, and transported to the surface alive in a perforated plastic jar.
