Abstract:
A new species of Panaqolus is described from material from the Takutu River and the mainstem rio Branco. The new species is diagnosed from congeners by its color pattern consisting of dark and light bars on the body, bands on the fins, and with dots and vermiculations absent (vs. no bars in P. albomaculatus , P. nix , P. nocturnus , and P. koko , vs. fins unbanded in P. albomaculatus , P. dentex , P. koko , and P. nix , and vs. dots and vermiculations present in P. albivermis and P. maccus ). The new species is diagnosed from barred species of Panaqolus by its specific bar number and orientation and color pattern on its head, with bars oriented in a anteroventral-posterodorsal direction (vs. anterodorsal-posteroventral bars in P. gnomus ), having consistently 5 bars (n = 4) on the trunk that do not increase with size (vs. number increasing with size in P. purusiensis and vs. 6-12 in P. changae ), and the color pattern on the head of straight lines extending from posterior to the eye to the snout margin, splitting in the middle portion of the line in larger specimens (vs. small, dense reticulate lines in P. changae ). Biogeographically, we infer that the new species ancestrally originated in the Amazon river, dispersing to the Takutu River after the Amazon captured part of the Proto-Berbice.

Neue Art: Panaqolus claustellifer = L 306

Jap, Herkunft und Phänotyp passen perfekt.

Hi,

steht im Paper auch explizit so drinnen

.

Zitat:

Panaqolus claustellifer is identified as a Panaqolus , L306, in the aquarium pet trade (Miller, 2002; Schraml & Schaffer, 2002). Panaqolus claustellifer is listed as Panaque sp. by de Souza et al. (2012) and Panaqolus n. sp. Tacutu L306 by Lujan et al. (2015).

Gruß,
Karsten

Es ist aber schon cooler eine neu beschriebene Art am Holotypen zu erkennen als es erst durchs spätere Lesen mitzubekommen. ;-)
