Allen 1, Joshua Drew 2 and Douglas Fenner 3 1) Department of Aquatic Zoology, Western Australian Museum, Locked Bag 49, Welshpool DC, Perth, Western Australia ) Biodiversity Synthesis Center, Field Museum of Natural History, 1400 South Lake Shore Drive, Chicago, Illinois 60605, USA 3) Department of Marine and Wildlife Resources, Pago Pago, American Samoa Received 27 April Accepted 27 June 2010 Abstract Amphiprion pacificus n. sp. is described on the basis of four specimens, mm SL, from Wallis Island and Tonga in the western Pacific. Underwater photographs also reveal its presence on coral reefs of Fiji and Samoa. The new taxon is nearly identical in appearance to A. akallopisos from the Indian Ocean. Both species are generally pinkish brown, grading to orange or yellowish on the lower half of the head and side and possess a white stripe on the dorsal midline of the head extending from just anterior to the eye to the dorsal fin origin, continuing along the base of the dorsal fin to the caudal fin base. However, genetic results indicate that A. pacificus is more closely related to A. sandaracinos from Western Australia and the Indo-Malayan region, forming a moderately supported clade that is well differentiated from A. akallopisos. Aside from genetic differences A. sandaracinos differs from A. pacificus in having a uniform orange colouration and the white forehead stripe extends onto the upper lip. There also appears to be modal differences in the number of soft dorsal and anal rays (usually 19 versus 18 and 13 versus 12 respectively for A. pacificus and A. sandaracinos). Zusammenfassung Die neue Art Amphiprion pacificus n. sp. wird auf der Grund lage von vier Exemplaren mit 30,9-48,3 mm SL be - schrieben, die an den Inseln Wallis und Tonga im West-Pazifik gefangen wurden. Unterwasserfotografien belegen außerdem ihr Vorkommen über Korallenriffen der Fidschiund Samoa-Inseln. Dem Erscheinungsbild nach ist das neue Taxon nahezu identisch mit A. akallopisos vom Indischen Ozean. Beide Arten sind braun mit einem Rosaton, der in einen orangefarbenen oder gelblichen Ton auf der unteren Kopf hälfte und an der Flanke übergeht; außerdem ist ein weißer Streifen auf der dorsalen Mittellinie des Kopfes kennzeichnend, der kurz vor dem Auge beginnt, sich bis zum Ansatz der Rückenflosse erstreckt und sich vom Rückenflos sen ansatz bis zur Basis der Schwanzflosse fortsetzt. Nach gene tischen Untersuchungsergebnissen dürfte A. pacificus jedoch eher mit A. sandaracinos von Westaustralien und dem indo-malaiischen Raum verwandt sein, sie bilden zusammen eine Klade mittlerer Ausprägung, die sich deutlich von A. akallopisos unterscheidet. A. sandaracinos unterscheidet sich wiederum von A. pacificus nicht nur genetisch, sondern auch im Aussehen: die Grundfarbe ist einheitlich orange, der weiße Stirnstreifen erstreckt sich bis zur Oberlippe. Auch die Mittelwerte der weichen Rückenflossen- und Afterflossenstrahlen ermöglichen eine Unterscheidung (19 im Vergleich zu 18 und 13 im Vergleich zu 12 bei A. pacificus bzw. A. sandaracinos). Résumé Amphiprion pacificus n. sp. est décrit sur base de quatre spécimens, 30,9-48,3 mm de LS, de l île des Wallis et de Tonga dans le Pacifique ouest. Des photos subaquatiques révèlent aussi sa présence sur des récifs coralliens des Fidji et de Samoa. La nouvelle espèce est d apparence quasi identique à A. akallopisos de l océan Indien. Les deux espèces sont généralement brun rosâtre, allant à l orange et au jaunâtre sur la moitié inférieure de la tête et du côté et ont une ligne blanche sur la ligne médiane dorsale de la tête, s étendant de la zone immédiatement antérieure à l oeil jusqu à la naissance de la dorsale, se continuant le long de la base de la dorsale jusqu à la base de la caudale. Toutefois, des données génétiques montrent qu A. pacificus est plus étroitement apparenté à A. sandaracinos d Australie occidentale et de la région indo-malaisienne, formant un clade moyennement établi, mais bien différent d A. akallopisos. A part les différences génétiques, A. sandaricinos se distingue d A. pacificus par une coloration orange uniforme et la ligne blanche frontale s étend jusque sur la lèvre supérieure. Il semble aussi y avoir des différences modales dans le nombres de rayons mous de la dorsale et de l anale (normalement 24 contre 18 et 13 contre 12 respectivement pour A. pacificus et A. sandaracinos.

2 Amphiprion pacificus, a new species of anemonefish (Pomacentridae) from Fiji, Tonga, Samoa, and Wallis Island esemplari di mm SL raccolti presso Wallis Island e Tonga, nel Pacifico occidentale. Fotografie subacquee di - mo strano la sua presenza anche lungo la barriera corallina di Fiji e Samoa. Il nuovo taxon è quasi identico per aspetto generale ad A. akallopisos dell Oceano Indiano. Entrambe le specie sono generalmente di colore bruno rosastro che scema verso l arancio o il giallastro sulla parte inferiore della testa e dei fianchi e, inoltre, possiedono una stria bianca sulla linea mediana dorsale della testa che si estende dalle orbite all ori - gine della pinna dorsale e continua lungo la base della dorsa - le fino alla base della pinna caudale. Tuttavia, analisi gene ti - che indicano che A. pacificus sia più vicino ad A. sandaracinos, una specie dell Australia occidentale e della regione Indo-Malaiana: esse formano una linea evolutiva piuttosto ben differenziata da A. akallopisos. Oltre a differenze geneti - che A. sandaracinos si distingue da A. pacificus per avere una colorazione uniformemente arancione e per la stria bianca che dal capo si estende fino al labbro superiore. Ci sono inoltre differenze modali nel numero di raggi dorsali e anali (di solito 19 vs.18 e 13 vs. 12 rispettivamente per A. pacificus e per A. sandaracinos). INTRODUCTION The brightly coloured members of the pomacentrid tribe Amphiprionini (see Cooper et al. 2009) are well known for their commensal relationship with large sea anemones. Allen (1972, 1980) provided comprehensive reviews of the group and summary of their biology. More recently, these fishes were treated by Fautin & Allen (1992), who recognized 27 species in Amphiprion Bloch & Schneider, 1801, and one species in Premnas Cuvier, An additional species of Amphiprion was described by Allen et al. (2008). The present paper describes a new species that was collected in 2000 at Wallis Island (about 575 km west of American Samoa) by colleague Jeff Williams of the United States National Museum. We subsequently received three additional specimens collected at Tonga. It has also been observed by the third author at several locations around American Samoa including Utelei, Aunu u, Fagaalu, and Fagatele Bay National Marine Sanctuary. Underwater photographs also indicate its presence at Fiji, although it is apparently rare. MATERIALS AND METHODS Lengths of specimens are given as standard length (SL) measured from the anterior end of the upper lip to the base of the caudal fin (posterior edge of hypural plate); head length (HL) is measured from the same anterior point to the posterior edge of the opercle flap; body depth is the maximum depth taken vertically between the belly and base of the dorsal spines; body width is the maximum width just posterior to the gill opening; snout length is measured from the anterior end of the upper lip to the anterior edge of the eye; orbit diameter is the horizontal fleshy diameter and interorbital width the least bony width; upper-jaw length is taken from the front of the upper lip to the posterior end of the maxilla; caudal-peduncle depth is the least depth, and caudal peduncle length is the horizontal distance between verticals at the rear base of the anal fin and the caudal fin base; lengths of fin spines and rays are measured to their extreme bases (i.e., not from the point where the ray or spine emerges from the basal scaly sheath); caudal fin length is the horizontal length from the posterior edge of the hypural plate to a vertical at the tip of the longest ray; pectoral fin length is the length of the longest ray; pelvic fin length is measured from the base of the pelvic spine to the filamentous tip of the longest soft ray; pectoral ray counts include the small splint-like, uppermost rudimentary ray; only the tube-bearing anterior lateral line scales are counted; a separate count is given for the deeply pitted scales occurring in a continuous series midlaterally on the caudal peduncle; gill raker counts include all rudiments and are presented as separate counts for the upper and lower limbs as well as a combined count; the last fin ray element of the dorsal and anal fins is usually branched near the base and is counted as a single ray. Counts separated by a backslash (/) indicate values taken from both sides of the holotype. We also conducted a molecular analysis to provide an additional set of characters on which to evaluate the specific status and evolutionary relationships of this species. Whole genomic DNA was extracted using Chelex 100 (Walsh et al. 1991). We amplified the 12s mitochondral gene using the primers CRA and CRE (Lee et al. 1995) and the following thermocycler parameters: An initial denature step of 94 C for 3 min followed by 40 cycles of denature 30s at 94 C, annealing 60s at 50 C, and extension 90s at 72 C with a 5 min extension period at 72 C. PCR amplicons were visualized on a 1% agarose gel and enzymatically cleaned for sequencing by digestion in 5 U of exonuclease I and 0.5 U of shrimp alkaline phosphatase for 30 min at 37 C followed by 15 min at 80 C. Samples were precipitated using 75% isopropanol prior to sequencing. Sequencing of both forward and reverse strands was performed on a 3730XL sequencer using Big Dye 3.1 terminator chemistry (Applied Biosystems) housed at the Pritzker Laboratory for Molecular Systematics and aqua vol. 16 no July

Bayesian phylogenetic reconstructions were made using MrBayes (Ronquist & Huelsenbeck 2003). Because of the small number of samples involved we used the GTR+I+gamma model of evolution allowing the program to run for 2,000,000 generations with a 25% burn-in period. We have also created a species page for the new taxon on the Encyclopedia of Life. This page will serve as a single electronic home for new information on all aspects of biology of A. pacificus including DNA sequences, evolution, ecology, and conservation status.

9 Gerald R. Allen, Joshua Drew and Douglas Fenner ance to A. akallopisos (Fig. 3), which ranges widely in the Indian Ocean from East Africa to western Thailand and western Indonesia, and to A. sandaracinos (Fig. 4), which occurs from Kalimantan, Indonesia to the Solomon Islands, north to the Philippines, Taiwan, and Ryukyu Islands, and south to Western Australia. The three taxa form a complex of allied species that share similar meristic and morphometric proportions, as well as similar colour patterns. They also share a host anemone preference, usually being associated with Heteractis magnifica. Fortunately, the three species exhibit allopatric distributions and are therefore easily separated on the basis of geographic range. Our genetic results (Fig. 5) indicate that A. pacificus and A. sandaracinos are closely related, forming a moderately supported clade that is well differentiated from A. akallopisos. The control region, which was utilised for the analysis, is known to be a quickly evolving gene (Bowen et al. 2006) and therefore is ideal for fine resolution phylogenetics and population genetic studies (Drew et al. 2010). The geographic, morphological, and meristic differences, in combination with the reciprocal monophyly at the mtdna control region, provide multiple lines of evidence supporting the validity of A. pacificus. The three species generally differ from other anemonefishes in having an overall pale colouration, lack of white bars on the head and body, and a whitish mid-dorsal stripe on the forehead region that extends along the base of the dorsal fin. In A. sandaracinos the forehead stripe is well contrasted and extends onto the upper lip (Fig. 4), whereas it is not as vivid in the other two species and fails to reach the upper lip. Moreover, the ground colour of A. sandaracinos is more or less uniformly orange in contrast to the other species, which are pinkish brown dorsally and have a strong yellow cast on the ventral half of the body. Although our genetic evidence indicates a closer relationship to A. sandaracinos, the new species is nearly identical in appearance to A. akallopisos. The nearest populations (Bali and Wallis Island) of these two species are separated by approximately 7,000 km. We have no doubt that the huge distributional gap is genuine and not a collection artifact. Anemonefishes are conspicous, often photographed elements of the reef fish fauna, and their distribution has been well documented in both popular and scientific media. The classification and biology of these fishes was the subject of the first author s doctoral thesis and since the publication of this work (Allen 1972) he has placed special emphasis on the details of their distribution. The known range of A. pacificus encompasses a sea surface area of approximately 870,000 km 2. This limited, relatively localised distribution is typical of many species of Amphiprion. Ten of the 29 known species have ranges that occupy similar or smaller areas. Moreover, the Fiji- Tonga region in particular, is recognised as an important regional hotspot of endemism with at least 30 reef fish endemics represented (Allen 2008; Drew et al. 2008). There appear to be modal differences in the number of anal rays and pectoral rays between A. pacificus (usually 13 and 17 respectively) and A. sandaracinos (usually 12 and 18), although additional specimens of the former species are required to confirm this discrepency. Similarly, there is an apparent modal difference in the total number of gill rakers on the first branchial arch between A. pacificus (usually 17) and A. akallopisos (18-19). These differences are summarised in Tables II and III. Distribution and habitat: Amphiprion pacificus is reliably known only from Fiji, Tonga, Samoa and Wallis Island. It does not appear to be common at any of these locations. It is generally commensal with the anemone Heteractis magnificus (Quoy & Gaimard, 1833) at depths between about 4-10 m. Etymology: This species is named Amphiprion pacificus with reference to the Pacific Ocean distribution. ACKNOWLEDGEMENTS We are especially grateful to Jeff Williams, who collected the holotype and provided a colour photograph of the freshly collected specimen. Scott Michael of Lincoln, Nebraska provided photographs and three paratypes of the new species, which he received from aquarium fish collectors at Tonga. Dive guide Josh Jensen sent us valuable photographs of the new species, confirming its presence at Fiji.
