New Species: Brachychalcinus reisi

A new species has been described in the Characidae family, sub-familiy Stethaprioninae: Brachychalcinus reisi. They originate from the tributaries of Rio Curuá in Brasil. They inhabit the small blackwater streams.

Abstract

Brachychalcinus reisi, a new species of characid fish, is described from the rio Curuá, tributary of rio Iriri, rio Xingu basin, Serra do Cachimbo, Pará State, Brazil. The new species can be distinguished from its congeners by the presence of a series of longitudinal black wavy stripes on the entire body and by a lower number of longitudinal scale rows between dorsalfin origin and lateral line (7–8 vs. 8–12). Additionally, the new species differs from B. copei, B. parnaibae, and B. retrospina by the lower number of branched dorsal-fin rays (9 vs.10). This is the first description of a new species of the subfamily since the revisionary study of Stethaprioninae, published almost 30 years ago.

Sinds ik op mijn twaalfde mijn eerste tweedehands aquarium kocht heb ik altijd wel een of meer aquariums gehad. Ik heb zelfs een garage ingericht als kweekruimte waarin ik in 50 aquariums zo'n 10.000 liter water in gebruik had. Op het moment heb ik nog twee aquariums. Een 1250 liter Tanganyika aquarium en een 250 liter gezelschapsaquarium met planten. De laatste 10 jaar heb ik aan deze website gewerkte als schrijver en fotograaf.
