Rheocles
''Rheocles'' is a genus of Madagascar rainbowfish. ''Rheocles'' has a restricted distribution, being found only in certain forested freshwater habitats in the central and eastern highlands of Madagascar including the Nosivolo River. The genus appears to feed almost exclusively on allochthonous material, primarily insects falling onto the water surface. Taxonomy In a 1990 study, this genus is monophyletic. However, in a 2004 analysis, it was found that ''Rheocles'' was paraphyletic, forming two distinct clades. ''R. alaotrensis'', ''R. lateralis'', and ''R. wrightae'' (all species that are not discernibly sexually dimorphic was recovered as the sister taxon of the rest of the bedotiids, including ''Bedotia'' sister to ''R. vatosa'' + ''R. derhami''. ''R. pellegrini'' and ''R. sikorae'' were excluded from this study due to lack of available material, however, ''R. sikorae'' is considered to be the sister taxon to ''R. wrightae''. Species There are currently seven recognized specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheocles Sikorae
''Rheocles sikorae'' is a species of rainbowfish in the subfamily Bedotiinae, the Madagascar rainbowfishes. It is Endemism, endemic to Madagascar where found in tropical rivers and streams. It can reach the maximum recorded length of . Distribution and status ''Rheocles sikorae'' is native to Madagascar, where found in the Mangoro stream, high valley of the east coast of the island, and in the Manambola River near Anosibe. At one point in time, this species was thought to be extinct, but since 1996 it has been collected from five forested stream localities near the town of Marolambo. Taxonomy and name ''Rheocles sikorae'' was Species description, described by Henri Émile Sauvage in 1891 as ''Eleotris sikorae'' with a Type locality (biology), type locality given as "Madagascar".
