Crenicichla wallacii group sensu Kullander (1990) was compose of six species (update in 1991,
with description of C. virgatula). Taxonomy revision of Crenicichla wallacii group had type
material and non-type found at nationals collections (INPA, MPEG, MZUSP), plus loans of
international collection in partnership (ANSP, Philadelphia, U.S.A.), original descriptions and
use of auxiliary tools for analysis (magnifiers, digital x-ray chamber). Examined a total of 500
examples of Crenicichla wallacii group and Teleocichla. Species recognized in wallacii group
in this revision: Crenicichla compressiceps (Tocantins- Araguaia rivers), C. notophthalmus
(Negro river), C. regani (Trombetas, Tapajós, Solimões, Uatumã, Purus, Madeira, Amazonas,
Guamá, Tocantins and Marajó rivers), C. virgatula (Branco river), C. urosema (Tapajós river),
and C. wallacii (Essequibo, Orinoco and Branco rivers). All this species presents diagnoses,
descriptions, color observations, sexual dimorphism, morphometric and meristic table and
geographic map distribution. In this project were proposed two new species, Crenicichla sp.
n. "Maicuru" (Maicuru river) and Crenicichla sp. n. "Xingu" (Xingu river), and a proposal to
withdraw Crenicichla heckeli out of wallacii group, hereafter, synonimize to genre Teleocichla.
It’s presented a identification key for eight species of Crenicichla wallacii group, restricted of
Amazon basin. At the end, presents a phylogenetic tree species analyzed (Crenicichla +
Teleocichla) with addiction species of different Crenicichla group and Taeniacara candidi as
outgroup, result that the wallacii group is monophyletic, and C. heckeli is outside the wallacii
group. |
