A new species of labrid fish, the Sunset Fairy-wrasse, Cirrhilabrus greeni n. sp., is described from seven specimens, 39.4-47.3 mm SL, collected from the eastern Timor Sea, Northern Territory, Australia. The species is clearly distinguished by its terminal-phase male color pattern, consisting of pink to reddish hues on the upper half of the head an...

... The species is named in honor of Tim Green of Monsoon Aquatics (Darwin, Australia), who collected the type specimens. Distribution and habitat. The new species is currently known only from the eastern Timor Sea (Fig. 5), approximately 300 km northwest of Darwin, Australia and 300 km southwest of the Tanimbar Islands of Indonesia. It was collected and observed in depths of about 18-40 m. The habitat consists of sloping rubble bottoms with scattered low outcrops of rock or coral and occasional large coral outcrops. It co-occurs with several other ...

... Phenotype and genotype discordance.-The strong selective pressure exerted by female mate choice is believed to have led to the rapid evolution of morphological diversity and reproductive isolation of the fairy wrasses (Victor, 2016;Allen and Hammer, 2017). This is well known in other groups of fishes (particularly the freshwater Cichlidae; see Dominey, 1984;Salzburger, 2009;Wagner et al., 2012;Selz et al., 2016), but more substantive evidence is lacking in the marine context. ...
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 identity of this taxon. Presently, the name has been applied to several fishes with notable differences in coloration, particularly in the terminal males. On the basis of additional non-type material and photographic examination of Bleeker’s holotype, we redescribe Cirrhilabrus solorensis and resolve the long-standing contention regarding its taxonomic identity. In doing so, we describe two species as new, Cirrhilabrus aquamarinus, new species, on the basis of the holotype and eight paratypes from Sulawesi and the surrounding islands of Banggai and Wakatobi, Indonesia, and Cirrhilabrus chaliasi, new species, described on the basis of the holotype and nine paratypes from Bali, Indonesia. These three species are closely related and, together with C. aurantidorsalis, C. cyanopleura, C. luteovittatus, C. randalli, and C. ryukyuensis, form a complex of species that differ from congeners in having the following combination of characters: caudal fin in males weakly rhomboidal; median fins hyaline with sinuous filigree in both sexes; body with scales edged in inky blue to indigo, their margins often patterned in an argyle motif; and osseus elements that preserve blue to blue-green in alcohol. We briefly discuss the phylogenetic relationships of species in this complex based on results of a companion study detailed elsewhere.
... Allen et al. (2015) listed 51 valid species in the genus. Seven other species have subsequently been described: Cirrhilabrus isosceles Tea et al. (2016), C. hygroxerus Allen & Hammer (2016), C. rubeus Victor (2016), C. africanus Victor (2016), C. efatensis Walsh et al. (2017), C. shutmani Tea & Gill (2017) and C. greeni Allen & Hammer (2017) bringing the valid species count to 58. Klausewitz (1976) erected the genus Cirrhilabrichthys to accommodate the placement of his new species, C. filamentosus. ...
... In his original description, Klausewitz made reference to the close relationship that C. filamentosus might have to Cirrhilabrus rubriventralis Springer & Randall (1974), based in part on the presence of a single row of cheek scales (versus the usual two). This apomorphic character is now known from several additional Cirrhilabrus species: C. rubripinnis Randall & Carpenter (1980), C. condei Allen & Randall (1996), C. morrisoni Allen (1999), C. tonozukai Allen & Kuiter (1999), C. joanallenae Allen (2000), C. walshi Randall & Pyle (2001), C. naokoae Randall & Tanaka (2009), C. humanni Allen & Erdmann (2012), C. marinda Allen, Erdmann & Dailami (2015), C. africanus Victor (2016), C. rubeus Victor (2016), C. hygroxerus Allen & Hammer (2016), and C. greeni Allen & Hammer (2017). Further study is required to determine whether this feature is synapomorphic, and thus diagnostic for Cirrhilabrichthys. ...
... An additional species, C. greeni, from the Northern Territory, Australia, also possesses the cheek scale character. Preliminary analysis of mitochondrial CO1 by Allen & Hammer (2017) revealed that it shares haplotypes with C. rubripinnis and C. cyanogularis (as C. aff. tonozukai). ...
Cirrhilabrus cyanogularis, sp. nov., is described on the basis of the holotype and three paratypes from Banguingui Island, Sulu Archipelago, Philippines, and a paratype from Sulawesi, Indonesia. The new species belongs to a complex consisting of C. filamentosus (Klausewitz), C. rubripinnis Randall & Carpenter, and C. tonozukai Allen & Kuiter. Aside from similar nuptial male coloration, the four species share the following character combination: a single row of cheek scales; dorsal-fin spines taller than dorsal-fin rays (slightly incised between spinuous and soft dorsal fin in C. rubripinnis and C. cyanogularis; last three dorsal-fin spines converging to form a single filament in C. tonozukai and C. filamentosus); relatively long pelvic fins (reaching past anal-fin origin); and isthmus and breast blue. The new species differs from the other members of the complex in lacking a dorsal filament, as well as possessing six predorsal scales, more extensive blue coloration on the isthmus, lower head and breast, and a soft dorsal fin with narrow black, medial stripe. The status of Klausewitz’s Cirrhilabrichthys is briefly discussed.
This study present the first report of two labrid fish species, Cirrhilabrus rubeus Victor 2016 and Paracheilinus mccoskeri Randall and Harmelin-Vivien 1977 for the first time from the Indian coast based on the specimens collected from the Gulf of Mannar waters, Bay of Bengal. Previously, the species Paracheilinus mccoskeri was known from East Africa, Persian Gulf, Comoro Islands, Maldives to the Andaman Sea and Western Indonesia and Cirrhilabrus rubeus was known only from Sri Lanka and the Maldives waters. In addition to the morphological analysis, the identity of both the species was also confirmed with molecular analysis and the genetic analysis divulges that the species P. mccoskeri has a close relationship with P. carpenteri, P. flavianalis and P. rubricaudalis with genetic divergence values of 5.6%, 5.4%, and 5.8% respectively and Cirrhilabrus rubeus exhibit 0% divergence with the type specimens.
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: short pelvic fins (not or barely reaching anal-fin origin); relatively unmarked dorsal and anal fins; males with a strongly lanceolate caudal fin (except in C. rubrisquamis); both sexes with a pair of prominent facial stripes above and below the orbit; and both sexes with prominent purple scales and osseus elements that persist, and stain purple, respectively, even in preservation. This group of fairy wrasse is part of a larger complex that includes related species from the western Pacific Ocean. In addition to meristic and morphometric comparisons, we also compare mitochondrial DNA sequence data to the aforementioned, putatively related species.
