Pseudancistrus reus
Jonathan W. Armbruster & Dolnald C. Taphorn
A new species of Pseudancistrus from the RÃ*o CaronÃ*, Venezuela (Siluriformes: Loricariidae) Abstract: Pseudancistrus reus is a new species from the RÃ*o CaronÃ* (RÃ*o Orinoco drainage) of Venezuela known from two individuals. It differs from all other Pseudancistrus by having a color pattern consisting of alternating dark and light bars. In addition, it differs from all except P. genisetiger and P. papariae by having an incomplete mid-dorsal plate row and from P. genisetiger and P. papariae by having 18 contiguous mid-dorsal plates vs. 14 plates, a plateless break and then two more plates at the end of the caudal peduncle. The type locality of P. reus was submerged by the construction of the Caruachi dam, and is also the only known locality of the gymnotiform Sternarchorhynchus gnomus, making it imperative that the conservation status of these and other potential CaronÃ* endemics be assessed. Pseudancistrus reus is the first species of Pseudancistrus sensu stricto from the Orinoco. Although the relationship of the species to other Pseudancistrus is unknown, P. reus may have gained access to the Orinoco either via stream capture between the CaronÃ* and the Rio Uraricoera (Rio Branco – Rio Negro drainage) or via stream capture between the CaronÃ* and either the CuyunÃ* or Mazaruni Rivers (Essequibo River drainage). viele Grüße Norman |
Hi!
Basierend auf 2 Exemplaren... na super... Ich vermute mal stark, dass Armbruster als Referee so eine Beschreibung nicht akzeptieren würde, aber er kann... tztztz Grüße, Christian |
