The specimen above, photographed in Raja Ampat, shows the ryukyuensis form of C. cyanopleura with an exaggerated elongation of the yellow flank, as well as obvious shading on the pre-operculum and operculum regions. Females are similar to the males, but show no distinction of a blue-sided hood; instead, the anterior region is pale greenish and poorly separated from the peach or orangey posterior half. solorensis has by far, the smallest range in this group. The Royal Dottyback: Pretty but Potentially a Royal Pain, Announcing ReefStock @ Home for Saturday, Nov 14, Time Capsule of German Mini Reef Aquariums from 1985, Aussie Reef Tank Build Pt. In addition, there is an immense amount of variation and possible hybridization, as well as a couple of distinct regional variations which likely deserve species recognition. We’re proposing in this article the usage of “Banda Fairy Wrasse” as the colloquial name, as it reflects this variant’s distribution with respect to the other clade members. The flat, monotonous and open habitat is often colonized by low-lying soft coral such as Xenia and Sinularia, in which the females and males frequently cavort around. The specimen above is 10cm in length, far larger than the usual size at which this phenotype is often photographed. Cirrhilabrus scottorum. The operculum is heavily shaded in deep indigo, and extends quite far ventrally so as to form a collar connecting both sides at the gular region. It is chiefly restricted to Western Australia, in the rubble pans of Hibernia Reef and Rowley Shoals in the Eastern Indian Ocean. These differences in coloration are useful characters for study, given that sexual selection is clearly helping to drive speciation here, but a precise breakdown of the interrelationships still eludes us. The head is rosy with a variable dusky posterior, just at the start of the dorsal fin, and the ventral region is blue. Throughout this Cirrhilabrus series, we’ve only highlighted the physical characteristics that set the various groups apart. This appears to be highly similar to the Balinese red headed Cirrhilabrus cf. Email me when available. No nuptial colors have been documented in this species so far, and as with the others, it most probably has very limited abilities in chromatic display. Save 64%. The species descriptions were published in Bleeker’s Ichthyological Atlas To Indonesian Fish. The ryukyuensis phenotype is most apparent in the Ryukyu Islands (Japan), as well as the northern Philippines. This is a feature most closely shared with the scottorum group, which is the presumed closest relative of cyanopleura. C. randalli is an exceedingly poorly documented species, with very little known to its name. From $39.99 : Sneaky Wrasse. Cirrhilabrus aurantidorsalis is one of a handful of species endemic to the region, and shares its habitat with the evolutionarily unique Paracheilinus togeanensis. All of these specimens apparently occur only in Komodo. At the northern limit in Lembeh, C. cf. This means that a whole spectrum of transitioning colors can present themselves during the development of the species throughout its various life stages, further blurring the lines of identification. The validity of this form as a species is subject of much debate amongst taxonomists and fish enthusiasts alike. In this case where C. cyanopleura is sympatric, sexual selection is the only plausible pressure for divergence where females identify males based on this brightly colored yellow flank. Together, the cyanopleura group can be diagnosed easily based on a few key characteristics shared amongst all the members. Conversely, the yellow-flank can be seen as something that isn’t developed only in terminal males, but seen in young males and matured females as well. The cyanopleura clade is home to two phenotypes and (depending on your taxonomic standpoint), consists of either one or two species. A plausible cause for this could be attributed to the yellow-orange dorsal mark being greatly exaggerated downwards. The split yielded Cirrhilabrus lyukyuensis, a species that is regarded by some to be nothing more than a color variant of C. cyanopleura. Perhaps the interaction between males and females of the cyanopleura group are largely dependent on their ability to see such fluorescence, which would otherwise be non-apparent to the human eye without the use of a filter. aurantidorsalis instead. Females of C. solorensis, despite also having a red head, never have it extending past the pectoral fin base. The phylogenetic tree presented here is the first of its kind to tackle this intractable group, but the relationships are still not fully resolved. aurantidorsalis and C. solorensis in Lembeh and Sulawesi. Despite their presumably distant evolutionary separation from one another, C. cyanopleura and its yellow-flanked “ryukyuensis” form are both capable of hybridizing with C. solorensis. Photo credit: Kazu. Kuiter suggests the name “Dull-head Fairy Wrasse”, after its blue-grey head. It is essentially a phylogenetic cipher, displaying evolutionary biology in its purest, most complex and intimate of forms. All males in this group possess on their median fins, an intricate network of sinuous squiggles, usually in blue or yellow. The lightening of the indigo scales and the faint emergence of an underlying orange along the dorsum in the specimen of C. solorensis above seems to suggest some genetic input from C. aurantidorsalis. C. temminckii was then selected to be the type species representing this new genus. The muddying of the facial region might also correlate to the largely dark purple-magenta face of C. aurantidorsalis. aurantidorsalis. solorensis and Cirrhilabrus cf. As the genus grew over the years, so did the cyanopleura group members, with Cirrhilabrus luteovittatus, C. randalli and C. aurantidorsalis being formally recognized, in 1988, 1995 and 1999 respectively. This species possibly strays into Raja Ampat, where it may hybridize with C. cyanopleura. Unlike Cirrhilabrus aurantidorsalis, this form is very sexually dichromatic, and only the males develop the orange back. This species bears one of the most unusual body colorations amongst the Cirrhilabrus. solorensis? The variability of the female form elsewhere in Cirrhilabrus is typically minimal, but Cirrhilabrus solorensis is a particularly mutable beast with few consistent characteristics. Cirrhilabrus cyanopleura was the first of its kind to be discovered and described in the mid 18th century. We feel that Cirrhilabrus cf. Yet another possible hybrid involving Cirrhilabrus cf. Some lightening of the dorsal fin may be expected. The typical chainmail pattern is seen along its entire length, but only in places where the golden-orange back does not occupy. The dusky head and pre-operculum markings strongly suggest genetic input from this “species”, but what about that vestigial yellow streak? Pseudojuloides cerasinus. This species suffers the unfortunate fate of having its name erroneously translated. This male with the same green patch above was photographed in Bali, alongside the typical redhead phenotype. The median fins are translucent blue to orange or yellow, and copiously adorned with yellow or cerulean sinuous squiggles throughout. From $139.99 : Sea Grass Wrasse. The females, being predominantly fulvous-rose colored, likewise look very dissimilar to the teal males. As previously mentioned in C. randalli, the northwestern region of Australia isn’t that far off from the Indonesian island chains, specifically the Banda Arc. 10.2305/IUCN.UK.2010-4.RLTS.T187706A8607422.en, "Cirrhilabrus blatteus Purple-boned wrasse", "Epithet etymology: The Purple-boned Fairy Wrasse", "A closer look at the extremely elusive Cirrhilabrus blatteus",, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 24 October 2020, at 16:05. The head is fuchsia to magenta, and the body is blue to purple. There are few (if any) morphological differences to help inform our understanding of the evolutionary relationships here, so, without the benefit of genetic study, we are left to rely on the nuances of color patterning to make our determinations. From $299.99 . As such, although diagnosing these species from other Cirrhilabrus groups may be easy, identifying them down to species level can be a process fraught with infuriating frustration. The blue hood gives this species its specific name “cyanopleura”, which translates to blue-side, although this in itself is rather misleading, as it is sometimes colored greenish or grey. Although this species has not been documented outside of its range, a few curious specimens that appear to be hybrids with traits of C. randalli have been documented in the Indonesian archipelago. [Update] The above two images were sent to us by Dr. Trond Erik Vee Aune from Norway post completion of the article. Novaculichthys macrolepidotus. The fins are hyaline and likewise riddled with the same sinuous markings as the males. Mixing fairy wrasses can be done but is best attempted in a larger aquarium. The difference between “Solor” and “Solar” may be only a single letter, but the implications it bears dramatically changes the etymology behind the species. The other members have it usually shaded in blue, especially on the pre-operculum cheek region. The collection of this fish in Darwin is possibly the first record of the genus crossing this divide into Australia’s northernmost territory. aurantidorsalis. solorensis is more fitting for this phenotype considering its placement in this clade. It becomes progressively less common further south in Indonesia. To further complicate things, the juveniles of C. solorensis are uniformly green, looking very dissimilar to the females. Etymology. The snout is also significantly reddened, and the yellow dorsal stripe from C. luteovittatus is strongly evident. This “species” is fairly common in the trade, and is frequently seen in imports originating from Bali, or having livestock that pass through facilities carrying Balinese fish. It shares this endemic range with Cirrhilabrus morrisoni, and the highly atypical Conniella apterygia. The specimen above is an unusual individual that sports the characteristic pre-operculum chevroned-shading associated with Cirrhilabrus cf. [3] The species can be found at depths of 40 to 50 meters. The head is cloaked in an inky blue-green hood that spreads to the posterior portion of the body, in much the same fashion that is seen in C. cyanopleura. Both forms are sympatric, but the latter is more evident in the northern territories, especially around Philippines and Japan. Future installations will feature the exquisitus complex and the temminckii group from the genus’ third clade, both of which are also ostentatiously complex and difficult. Ventrally, this species is unmarked and uniformly white (or sometimes a light yellow), with the lower head always being a pristine and blemish-free white. solorensis from Bali, as well as the females of the other Indonesian clade members. The development of the purple area proximal to the red head and intensification of the ocherous back suggests that this “species” is perhaps more likely to be related with Cirrhilabrus aurantidorsalis and Cirrhilabrus cf. It reaches its western limit in Bali, and its northern limit in the straits of Lembeh, where it mixes in a narrow contact zone with its sister, C. aurantidorsalis. Cirrhilabrus blatteus is found above rock and coral bottoms, usually within 1-2m of the substrate where it feeds on zooplankton. The fins are translucent yellow and are copiously riddled with the sinuous squiggling characteristic of this species group.
