Última NEW RECORDS OF HATCHERIA MACRAEI (SILURIFORMES, TRICHOMYCTERIDAE) FROM CHILEAN PROVINCE Gayana Unmack,Peter J; Habit,Evelyn M; Johnson,Jerald B. We describe collections oiHatcheria macraei (Patagonian catfish) from south-central Chile. This represents a significant range extension for this species. These new records have important biogeographic implications as H. macraei is now recorded within Chilean Province, far north of its previous distributional limit in Patagonian Province. We document a new character, the shape of the dorsal fin, which allows quick and easy discrimination between H. macraei and Trichomycterus areolatus in the field or laboratory. This study highlights the need for careful identification for trichomycterid catfishes from southern Chile.

Zool. Koch,Walter Rudolf. The genus Homodiaetus Eigenmann & Ward, 1907 is revised and four species are recognized. Its distribution is restricted to southeastern South America, from Uruguay to Paraguay river at west to the coastal drainages of Rio de Janeiro State, Brazil. Homodiaetus is currently distinguished from other genus of Stegophilinae by the combination of the following characters: origin of ventral-fin at midlength between the snout tip and the caudal-fin origin; opercle with three or more odontodes; and gill membranes confluent with the istmus. Homodiaetus anisitsi Eigenmann & Ward, 1907, is diagnosed by the caudal-fin with black middle rays, margin of upper and lower procurrent caudal-fin rays with dark stripes extending to the caudal-fin, and 3-6...

C.. ABSTRACT A review is made of the impact of the landmark Ph. D. Thesis of Jonathan N. Baskin from 1973 on the development of the phylogenetics of catfishes and some of its main subgroups and on neotropical ichthyology in general. Baskin's work is the first to propose a hypothesis of relationships for loricarioid catfishes and for the family Trichomycteridae on the basis of explicit Hennigian principles. It is arguably also the first application of phylogenetic methods to any group of neotropical fishes. The hypotheses presented by Baskin covered the monophyly of Siluriformes, the monophyly and relationships of loricarioid families and the relationships of Trichomycteridae (including the monophyly of the family and the relationships among its constituent...

The trichomycterid catfishes known as candirus are renowned for their blood feeding, but information on their habits under natural conditions is very fragmentary and generally restricted to hosts or habitats. We recorded an undescribed species of the vandelliine genus Paracanthopoma riding the giant jau catfish, Zungaro zungaro (Pimelodidae), in the upper Amazon. The candirus were found on the host's caudal and pectoral fins, as well as the base of the dorsal fin, with their snouts buried up to the eyes in the tough skin of the catfish host. All of them had small amounts of partly digested blood in the distal part of the gut. Along the host's dorsal fin base we found a few additional tiny holes, most of them healed. We suggest that Paracanthopoma feeds on...
