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. Could this be a regional form of Cirrhilabrus cf. 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. The males not only produce this fluorescence, but they also are able to see and recognize it. The resultant formation of the bay served as an isolation barrier, locking in its species and setting the platform for evolution. Select options. Constellations of metallic blue spots are sometimes present along its length. To date, this group is shrouded in much taxonomic confusion and mystery. With the exception of Cirrhilabrus luteovittatus and C. randalli, the solorensis group members are wholly confined to the Indonesian archipelago. C. randalli is an exceedingly poorly documented species, with very little known to its name. In Cirrhilabrus luteovittatus, males range from a rich burgundy to bordeaux and lack any distinct posterior hood. 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. Pseudojuloides cerasinus. The ryukyuensis phenotype is most apparent in the Ryukyu Islands (Japan), as well as the northern Philippines. 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. 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. In examining the above cladogram, two major lineages can be seen. While hybridization events are rarely documented in Cirrhilabrus, we’ve seen some examples from the lunatus and scottorum groups, with the latter engaging in intra-group hybridization with Cirrhilabrus exquisitus. This habitat’s flora and fauna is quite niche and specific to the Micronesian and Marshall Island chains, and is shared with a few other sympatric species such as Cirrhilabrus johnsoni and C. rhomboidalis. solorensis range outside of Bali, east to Komodo? The amount of phenotypic expression from each parent ranges between specimens, and in the three individuals above, the amount of green displayed from the genetic input of C. cyanopleura varies in its intensity, clarity and position. Starting at : $120.99. Required fields are marked *. 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 only noticeable color change during this event is the lightening of the posterior dorsal fin and the facial region. aurantidorsalis is very similar to its preceding sister, and is colored nearly exactly the same except for major differences in the head and ventral regions. The female forms and the individual parents are far too variable to produce any consistent looking hybrids. Another Cirrhilabrus was collected along with this, and that will be described in a separate article. Still, this is another example where lines are blurred, and only educated guesses can be put forth. Cirrhilabrus sanguineus Cornic, 1987 (Red-blotched fairy-wrasse) Cirrhilabrus scottorum J. E. Randall & Pyle, 1989 (Scott's fairy-wrasse) Cirrhilabrus shutmani Y.K. C. cyanopleura may also be another candidate for hybridization, as seen in the photo above. Cirrhilabrus solorensis is confined to the Indonesian archipelago, where it ranges from the Flores and Banda Seas to Northeastern Sulawesi. 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. The blunt, truncated head shape also points in the direction of that “species”. This species is the least sexually dichromatic of the group, and perhaps even the genus. Cirrhilabrus cyanopleura is wide ranging, being found predominantly in the Western Pacific, where it occurs in the Ryukyu Islands (Japan), Taiwan, Thailand, Philippines, Papua New Guinea, Palau, Indonesia and south to the Great Barrier Reef. The variability of the female form elsewhere in Cirrhilabrus is typically minimal, but Cirrhilabrus solorensis is a particularly mutable beast with few consistent characteristics. Females of C. solorensis are frightfully similar to the males of C. cf. Like the other cyanopleura group members, males are often seen flocking in large aggregations. Cirrhilabrus scottorum var. 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. This species is fairly uncommon, but is never expensive. The sympatric overlap and weak evidence supporting speciation has generated mixed consensus on the validity of C. ryukyuensis as a legitimate species. Tunze Care Booster Review, Floating Magnets are Stronger! A fairly common aberration involves C. luteovittatus developing a highly xanthic dorsum, which in extreme cases can totally obliterate the underlying burgundy ground color and merge with the existing yellow stripe.
