With over 600 valid species, the wrasses (family Labridae) are among the largest and most successful families of the marine teleosts. They feature prominently on coral reefs where they are known not only for their impressive diversity in colouration and form but also for their functional specialisation and ability to occupy a wide variety of trophi...

Australian species of the cirrhilabrin labrid genus Paracheilinus are reviewed. Four species of Paracheilinus are report- ed from Australian waters: P. amanda, new species, from Flora, Holmes, and Osprey Reefs, Coral Sea, off northeast Queensland, and Harrier Reef, Great Barrier Reef; P. filamentosus from Lizard Island, Great Barrier Reef; P. flavi...

The new species is distinctive in having a pale yellowish to jade...

Adaptive radiation as a result of ecological opportunity can have profound effects on the evolutionary outcome of species. On coral reefs, parrotfishes have been considered as one of the most dramatic examples of adaptive radiation unique in their extreme dietary specialisation. Using abrasion-resistant biomineralized teeth, parrotfishes are able t...

Nemateleotris lavandula, new species, is described on the basis of the holotype from Augulupelu Reef, Palau, and twelve paratypes from across the western and central Pacific Ocean, including Fiji, Guam, Japan, and the Marshall Islands. The new species was previously confused with Nemateleotris helfrichi, but molecular analysis of mitochondrial COI...

Cirrhilabrus rubrisquamis is redescribed on the basis of the juvenile holotype and compared to known species of Cirrhilabrus . Examination of material from the Maldives identified as C. rubrisquamis reveal differences from the holotype collected from the Chagos Archipelago. Consequently, the Maldivian specimens are herein described as Cirrhilabrus...

Significance The evolution of asexuality is thought to be prevented when males play a critical role beyond that of gamete provision. We demonstrated high numbers of neo-sex chromosomes and enhanced heterozygosity in males of the termite Glyptotermes nakajimai , which appears to compensate for inbreeding within termite colonies. Furthermore, we show...

Conniella apterygia is redescribed from re-examination of the holotype, two paratypes, and six additional specimens. The genus is closely allied to Cirrhilabrus, sharing similarities in general morphological and meristic details, but is separated from Cirrhilabrus and most other labrid fishes in lacking pelvic fins and a pelvic girdle. Recent molec...

The pseudochromid Labracinus atrofasciatus (Herre, 1933) is redescribed based on examination of the holotype from Culion, Calamian Islands, and three newly acquired non-type specimens from a fish landing site in Barangay Sandoval, Municipality of Taytay, northern Palawan, Philippines. Prior to this, the species was known only from the holotype; fro...

Milkweed butterflies (Lepidoptera: Nymphalidae: Danainae) are chemically defended and aposematic (Ackery and Vane Wright 1984). The chemical ecology of several species have been studied extensively, including the iconic and highly migratory Monarch Butterfly, Danaus plexippus (Brower and Glazier 1975; Boppré 1993). Danaine larvae feed on chemically...

The labrid fish Cirrhilabrus solorensis was first described in 1853 by Bleeker, based on specimens collected from the Indonesian island of Solor, off the eastern tip of Flores in the Lesser Sunda Islands. Although sufficient at the time, Bleeker’s description of the species was brief, resulting in subsequent taxonomic confusion concerning the true...

Three new species of anthiadine species are described from specimens trawled from Australian waters. Pseudanthias paralourgus n. sp. is described from five specimens collected off southeastern Queensland. It resembles P. elongatus (Franz, 1910) from Japan to the South China Sea, but differs in male live coloration. The remaining two species are ass...

The fairy wrasses (genus Cirrhilabrus) are among the most successful of the extant wrasse lineages (Teleostei: Labridae), with their 61 species accounting for nearly 10% of the family. Although species complexes within the genus have been diagnosed on the basis of coloration patterns and synapomorphies, attempts to resolve evolutionary relationship...

Animals follow cyclical patterns in their abundance. But what causes episodic cycles of super abundance? We grabbed the once-in-a-decade opportunity of mass emergence of swallowtail moths in Singapore in 2014 to learn about their life cycle and ecology. We explaine what might have caused this episodic cycle.

Pseudojuloides pluto, new species, is described on the basis of the holotype and 11 paratypes from Wake Island, northeastern Micronesia, and nine paratypes from the Maug Islands, Northern Mariana Islands. The new species has previously been confused with Pseudojuloides atavai, but molecular analysis of mitochondrial COI reveals a difference of 6.8%...

The anti-equatorial labrid Pseudojuloides elongatus has a wide but disjunct distribution across the Western Pacific and Eastern Indian Oceans, with populations occurring in Western Australia, southern Japan, and the southwest Pacific Ocean. Principal component analysis of morphological characters and coalescent-based species-tree estimates of mitoc...

Hybridization events are not uncommon in marine environments where physical barriers are attenuated. Studies of coral reef taxa have suggested that hybridization predominantly occurs between parapatric species distribu- ted along biogeographic suture zones. By contrast, little is known about the extent of sympatric hybridization on coral reefs, des...

The taxonomy and classification of the microcanthid fish genus Microcanthus Swainson has been a subject of contention dating back to the 19 th century. Its allopatric, disjunct anti-equatorial distribution across the Indo-West Pacific has resulted in the recognition of several nominal taxa, though these have been widely regarded as synonyms of Micr...

The tropical swallowtail uraniid moth Lyssa zampa is known to exhibit seasonal patterns of mass emergence throughout its range. These cyclical patterns of emergences are thought to correlate closely with oscillating host plant availability, as well as with interactions between herbivory and host plant defences. Because little has been reported conc...

The new species, Cirrhilabrus briangreenei, is described on the basis of the holotype and six paratypes collected from mesophotic coral ecosystems of the Verde Island Passage, Philippines, between depths of 82 and 110 m. The new species is most closely related to Cirrhilabrus pylei, but it differs primarily in the presence of: more pored scales on...

Ichthyofaunal assemblages of mesophotic coral ecosystems (MCEs) remain largely uncharacterized in the Western Indian Ocean. Recent underwater exploration of MCEs on the island of Réunion in the Mascarene Archipelago, Western Indian Ocean, resulted in several high-quality photographs of the island's deep reef ichthyofauna. We report new distribution...

Cirrhilabrus wakanda sp. nov. is described on the basis of the holotype and four paratypes collected between 50 and 80m depth over low-complexity reef and rubble bottoms at the east coast of Zanzibar, Tanzania, Africa. The new species belongs to a group of fairy wrasses from the western Indian Ocean, sharing a combination of characters that include...

The geographic distributions of marine fishes have been shaped by ancient vicariance and ongoing dispersal events. Some species exhibit anti‐equatorial distributions, inhabiting temperate regions on both sides of the tropics while being absent from equatorial latitudes. The perciform fish Microcanthus strigatus (the stripey) exhibits such a distrib...

Pomacentrus vatosoa, new species, is described on the basis of four specimens collected from Nosy Faho, Madagascar. The new species is distinctive in having a pearlescent-white body with a large black spot midlaterally behind the pectoral fin, a black saddle of similar size on the dorsal edge of the caudal peduncle, and a black recurved band from t...

Chromis tingting sp. nov., is described on the basis of the holotype and three paratypes from Sagami Bay, Japan. The new species likely belongs to a complex consisting of C. mirationis, C. okamurai and C. struhsakeri, with which it shares the following character combination: dorsal rays XIV,13-14; anal rays II,12; pectoral rays 19-20; tubed lateral...

The labrid fish Cirrhilabrus sanguineus Cornic is redescribed on the basis of the neotype, two male specimens, and an additional female specimen recently collected from the northern coast of Mauritius. We provide new live and nuptial colouration descriptions, as well as the first documented female specimen for the species. we also include a molecul...
