Issue
New combination with type species designation by Bleeker (1862:2); information on the holotype and type locality in Isbrücker (1992); complementary descriptions in Günther (1864:242) and in Regan (1904:229); recent material redescribed with ecological observations in Le Bail et al. (2000:234, fig.). Mitochondrial D-loop sequences used in a molecular phylogeny of Hypostomus and related genera by Montoya-Burgos and Weber (in press, fig. 2; EMBL/GenBank AJ318368).

生物学特性     字汇 (例如 epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Lives in the main jets of rapids where the current is very strong. The substrate consists of bulky rocks which gives them shelter. Occurs together with the following species: Leporinus granti, Astyanax meunieri, Bryconops caudomaculatus; Parodon guyanensis, Harttia surinamensis, Hypostomus gymnorhynchus, Lasiancistrus brevipinnis and Heptapterus longior (Ref. 35381).

生活在水流是非常强的急流的主要喷射。 底部由给他们庇护所的庞大的岩石组成。 生存伴随着下列的种: 格氏兔脂鲤[Leporinus granti] Astyanax meunieri, 尾斑瑙脂鲤[Bryconops caudomaculatus] ; Parodon guyanensis 苏里南哈氏甲鲶[Harttia surinamensis] Hypostomus gymnorhynchus, Lasiancistrus brevipinnisHeptapterus longior.(参考文献 35381)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00531 - 0.02848), b=2.97 (2.76 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
