The males of this phenotype resemble the females of Cirrhilabrus solorensis very closely, and may cause initial confusion. C. solorensis was first known in 1853, when digital cameras, image scanners and other technological advancements were not available. The median fins are of the usual translucent nature, decorated with yellow and blue sinuous scrawling. A case of biogeographical uncertainty is displayed with Cirrhilabrus aurantidorsalis, C. solorensis and C. cf. It is most often seen in the Togean Islands, and it strays to the northeastern tip of Sulawesi in the straits of Lembeh. Save 55%. Email me when available . This species suffers the unfortunate fate of having its name erroneously translated. It is important to note that the members of this group can be wildly variable, especially for those in the solorensis clade. The split yielded Cirrhilabrus lyukyuensis, a species that is regarded by some to be nothing more than a color variant of C. cyanopleura. The typical chainmail pattern is seen along its entire length, but only in places where the golden-orange back does not occupy. In all likelihood, this characteristic was either independently evolved in both taxa or present in their shared common ancestor. Unlike Cirrhilabrus aurantidorsalis, this form is very sexually dichromatic, and only the males develop the orange back. Add to cart. This is the deepest occurring member of the cyanopleura group, and the very prominent yellow band probably aids in communication down in these depths the same way red does in shallower waters. The scaling along the anterior dorsum is also noticeably darker, a trait that is very evident in males of C. solorensis. 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. This may seem like a superficial distinction, but the presence, or lack thereof, of this trait will serve as a highly effective criterion in deciding the placement of the cyanopleura group members. A plausible cause for this could be attributed to the yellow-orange dorsal mark being greatly exaggerated downwards. Compare the hybrid with the pedigree C. cyanopleura in the background, and these traits become immediately apparent. This would suggest genetic involvement with one of the striped species of the solorensis clade, and with C. randalli confined to the far-flung region of Northwestern Australia, Cirrhilabrus luteovittatus from Micronesia seems more likely. solorensis has by far, the smallest range in this group. The yellow equatorial streak in both species could be regarded as a shared trait, once widespread across the Pacific but subsequently lost in the evolution of the other group members. The reddish head and operculum markings are consistent with those of C. solorensis in the female form, and the light yellow flank corresponds to a development of the trademark ryukyuensis phenotype. The Molucca Seas probably limit the invasion of C. cf. The caudal fin is strongly rhomboidal in terminal males. There are typically six poorly defined lines running along lengthwise along the body, which are composed of numerous minute, reflective-blue spots. The tails are rhomboidal in large terminal phased males. More on this will be discussed in the hybrid section below. solorensis are very similar to various females of other closely related species. He later released a hand drawn illustration of the species in a separate publication, but the colors were not too accurately represented. This male with the same green patch above was photographed in Bali, alongside the typical redhead phenotype. C. luteovittatus is allopatric in distribution with regards to its group members, but should it waif to nearby Raja Ampat in the Papuan region, there is, in all likelihood, a chance for a hybridization event to occur. In examining the above cladogram, two major lineages can be seen. The presence of the purple lateral line patterning is highly variable in the Indonesia C. cf lubbocki, with some individuals having it quite prominent, many others having only a faint trace, and others still which seem to lack it entirely. The Velvet Fairy Wrasse is often referred to as the Velvet Multicolor Fairy Wrasse, Purple Velvet Wrasse, Yellowstreaked Fairy Wrasse, Yellowband Wrasse. However, the original epithet for Ishigawa’s “lyukyuensis” was incorrect, and it was only in recent years was it amended to “ryukyuensis”, after the Ryukyu Islands of Japan. All males in this group possess on their median fins, an intricate network of sinuous squiggles, usually in blue or yellow. The only noticeable color change during this event is the lightening of the posterior dorsal fin and the facial region. However, whether or not the ryukyuensis form is indeed a diverging taxon capable of maintaining genetic distinction, or whether it will eventually hybridize back into a single homogenous taxon remains unknown for now. The scale margins are edged in dark green or violet, and are inconsistently distributed. The sympatric overlap and weak evidence supporting speciation has generated mixed consensus on the validity of C. ryukyuensis as a legitimate species. The fins are translucent yellow and are copiously riddled with the sinuous squiggling characteristic of this species group. Email me when available. Cirrhilabrus randalli is one of the least known of the genus, and in this enigmatic species, the males bear the greatest resemblance to Cirrhilabrus luteovittatus. Because the males of this species are so similar to the females of the former, aquarists have tried, in much futility, to place the two together in hopes of creating a sexually functional pair or a harem. From the very few photos of this species in situ, it appears that the body stripe lightens to a pale chalk, while the rest of the body remains unchanged. 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. An additional set of characteristics that is confined only to the solorensis clade in this group is the heavy shading of the operculum. The difference between “Solor” and “Solar” may be only a single letter, but the implications it bears dramatically changes the etymology behind the species. Unlike many Cirrhilabrus, where males are greatly outnumbered by females, males of the cyanopleura group are often seen in large flocks, sometimes outnumbering or equaling the number of available females. The living coloration of C. solorensis was unknown to many then but eventually revealed itself through the passing of time. In the lanceolatus group article, we attributed the lack of ventral fins in Conniella to a genetic bottleneck event. The ventral, anal and caudal fins clamp up while the dorsal is raised. lubbocki, lanceolatus, bathyphilus and lunatus). The same can be said for the third endemic wrasse in Northwestern Australia, C. morrisoni, but that is a subject for a future article in this series. Strangely enough, little, if any, photographic documentation exists showing the group members in nuptial form. C. temminckii was then selected to be the type species representing this new genus. Cirrhilabrus aurantidorsalis could be speciating right now due to its geographical isolation, or the two population might have already been speciated, but recently reconnected in their ranges. For instance, Gerry Allen regards these to be a local male variant of Cirrhilabrus cyanopleura, while Rudie Kuiter regards these as female. The clade members generally possess either blue markings or dusting along the pre-operculum and operculum flap, and in some species, this can be so noticeable that is forms a distinct chevron on the gill plate. solorensis occurs in exceedingly large numbers at the various local wholesalers. Photo credit: Kazu. As previously mentioned in C. luteovittatus, C. randalli and the former may appear to be sisters, but their geographical range does not fully support this hypothesis. The females are a dusky greenish-grey and adorned all over with the chainmail like markings of this group. Constellations of metallic blue spots are sometimes present along its length. solorensis and Cirrhilabrus cf. This hybrid individual appears to still be in the female stage, or at least transitioning into the male form. About 2.8-5.3 million years ago since the Pliocene, submarine sediment gravity flow was the major mechanism of sediment transportation from the slope to deep-sea environments in the Tomoni and Gorontalo Basins (Kusnida and Subarshyah, 2008). A bright yellow equatorial belt runs horizontally along its length in the same way it does for C. luteovittatus and tapers toward the caudal peduncle. Perhaps this “species” is indeed synonymous with the Komodo population. Ventrally, the species is white and unmarked. If so, then the lack of chromatic brilliance during nuptial display is not so much an evolutionary disadvantage, but an advantage, seeing as most other Cirrhilabrus probably use physical color change as a behavioral cue. So does Cirrhilabrus cf. The Gulf of Tomini was formed during the late Neogene collision between the East Sulawesi Ophiolite Belt and the micro continent Banggai-Sula platform. The existence of this species in the trade is probably incognito, seeing as many members in this clade are easily confused with each other. As with Cirrhilabrus cyanopleura, the ryukyuensis phenotype exhibits weak changes in its nuptial display. aurantidorsalis and C. solorensis in Lembeh and Sulawesi. Cirrhilabrus solorensis is not known to display any visible nuptial coloration, but, as mentioned in the group discussion previously, the males are able to emit red fluorescence in their excited state around the operculum and dorsum region. The median fins are translucent blue and overlaid in the same sinuous scrawling. The ventral portion is a lighter, mangosteen purple to white. 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. Cirrhilabrus cf. The population density in suitable areas may be so great that more than one male may be seen interacting together in a given space, an unusual occurrence for this genus. The ryukyuensis form of C. cyanopleura never develops such extensive elongation of its yellow flank, and this could possibly point to the occurrence of C. randalli in Indonesia. Perhaps what we are seeing here is a mix of Red-head and Banda wrasse DNA, or perhaps we still know too little about the variability present in these taxa to draw firm conclusions. solorensis has by far, the smallest range in this group. Cirrhilabrus randalli is essentially a book fish, and the species has never been (and probably will never be) collected for the aquarium trade due to its isolated and far-flung range. Cirrhilabrus luteovittatus is relatively uncommon in the trade, but it is affordable and only moderately expensive. This species is capable of forming hybrids with Cirrhilabrus cyanopleura and possibly with Cirrhilabrus aurantidorsalis. Allen and Erdmann lists the maximum size for the group members at 10-11 cm, but aquarium housed specimens have the potential to get much larger, up to 15cm. aurantidorsalis? 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. solorensis x C. cyanopleura were added post completion of this article. The species appeals greatly to the novice aquarist, ticking all the right boxes for affordability, hardiness and visual appeal. Required fields are marked *. Our site uses cookies. The caudal fin is a rough rhombus, becoming increasingly spade like in terminal males. These hybrids often appear very similar to their pedigree parents, especially in specimens that lean more toward one parental phenotype. Again, too many questions, and very little answers. South of this range, it is replaced by a very similar species, Cirrhilabrus cf. This species possibly strays into Raja Ampat, where it may hybridize with C. cyanopleura. Pteragogus cryptus. Tea & Gill, 2017 (Magma fairy-wrasse) Cirrhilabrus solorensis Bleeker 1853 (Red-eye fairy-wrasse) Cirrhilabrus squirei F. M. Walsh, 2014 (Squire's fairy-wrasse) Like C. cyanopleura, the yellow-flanked form occurs in large aggregations above rubble patch reefs where they mingle with other species that occupy the same niche.
