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. Their caudal fins are rounded to weakly triangular in all but the largest and most terminal males, in which they become strongly rhomboidal. Ventrally, the species is white and unmarked. This appears to be highly similar to the Balinese red headed Cirrhilabrus cf. This form is treated by Ishigawa as a distinct species, known as Cirrhilabrus ryukyuensis. Color change is restricted only to lightening of the dorsal fin and the nape immediately anterior to the dorsal fin. With the exception of Cirrhilabrus luteovittatus and C. randalli, the solorensis group members are wholly confined to the Indonesian archipelago. This species is capable of forming hybrids with Cirrhilabrus cyanopleura and possibly with Cirrhilabrus aurantidorsalis. To make things even more trying, there is one final cyanopleura group phenotype that we cannot explain.

The ryukyuensis phenotype is most apparent in the Ryukyu Islands (Japan), as well as the northern Philippines. Not enough is known. The males hold territories and guard herams of females.[6]. Kuiter suggests the name “Dull-head Fairy Wrasse”, after its blue-grey head. Its westernmost limit in the Indonesian region lies in Bali, where it is rare. Cirrhilabrus cf. lubbocki, lanceolatus, bathyphilus and lunatus). Pteragogus cryptus.

As with the other group members, the scales are edged thickly in dark violet, but this characteristic, along with its operculum markings, are less obtrusive in this species due to its dark ground coloration. Etymology. The ventral fins are in the usual form for this group and are of moderate length. 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. 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. Naturally, the larger the aquarium, the better the fish will be. As an added level of complication, the group members are also able to hybridize, and in this article we again revisit this infrequently discussed topic. The Molucca Seas probably limit the invasion of C. cf. Whether or not the two species once swam together prior to their current “disjunct” ranges, or whether or not they evolved convergently is left to be unanswered. For instance, Gerry Allen regards these to be a local male variant of Cirrhilabrus cyanopleura, while Rudie Kuiter regards these as female. As with many Cirrhilabrus, males are able to puff up their gular region during display. Cirrhilabrus blatteus or the purple-boned wrasse is a species of fairy wrasse native to the coasts of Egypt, Eritrea, Israel, Jordan, Saudi Arabia, Sudan, and Yemen in the Gulf of Aqaba. Save 64%. 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. [Update] The above two images were sent to us by Dr. Trond Erik Vee Aune from Norway post completion of the article. Not only does this make identifying them very difficult, it also fuels the already numerous misidentification in the aquarium trade. 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. aurantidorsalis, which will be elaborated upon in the individual species discussion. 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. 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. As explained in C. aurantidorsalis, the relationship between these two forms are unclear.

Strangely enough, little, if any, photographic documentation exists showing the group members in nuptial form. Not only are we unable to resolve the phylogeny and cladistic relationships, we are also unable to fully understand and rationalize the various hybrid combinations occurring throughout Indonesia. aurantidorsalis. 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.

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. The solorensis clade houses six phenotypes, four of which are described, while the other two await further studies. C. solorensis was first known in 1853, when digital cameras, image scanners and other technological advancements were not available. The existence of this species in the trade is probably incognito, seeing as many members in this clade are easily confused with each other. solorensis has by far, the smallest range in this group.

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 is a beautiful species with a very fitting and descriptive name. Add to cart. Some aquarists have used the superficial similarities of this species as justification for its inclusion alongside the cyanopleura group, but it is clear from the considerable differences in nuptial patterns and pelvic fin shape that this is not so. 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. Cirrhilabrus cyanopleura appears to be equally common throughout its range, whereas the “ryukyuensis” form is more restricted in its distribution. Females of C. solorensis are frightfully similar to the males of C. cf. 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.

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. Despite our best efforts in trying to resolve this group, there are inevitably some open-ended mysteries limited by our capabilities. This group is the most phylogenetically confusing of the Cirrhilabrus genus thus far, and with members that are so commonly encountered in the field and in the trade, you would think that more would be known about this group than any other. Cirrhilabrus solorensis hybridizes with C. cyanopleura in areas where the two are sympatric. Select options. Its description was based on a two page, barely informative paper published in Bleeker’s guidebook of Indonesian fishes. This has led to many specimens being erroneously identified in the wild and in the trade; many of these identifications have been permanently etched in literature. The median fins are of the usual translucent nature, decorated with yellow and blue sinuous scrawling. solorensis is ferruginous-ochre along its body, with darker edged scales and a maraschino cherry head that extends posteriorly into a hood. The females of Cirrhilabrus aurantidorsalis are similar to the males, and have orange backs in all stages with the exception of very small juveniles, which are dusky brown and unmarked. 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.
