"Philosciidae" (Crustacea: Isopoda: Oniscidea)
Org. Divers. Evol. 1, Electr. Suppl. 4: 1 -85 (2001) © Gesellschaft für Biologische Systematik http://www.senckenberg.uni-frankfurt.de/odes/01-04.htm Phylogeny and Biogeography of South American Crinocheta, traditionally placed in the family "Philosciidae" (Crustacea: Isopoda: Oniscidea) Andreas Leistikow1 Universität Bielefeld, Abteilung für Zoomorphologie und Systematik Received 15 February 2000 . Accepted 9 August 2000. Abstract South America is diverse in climatic and thus vegetational zonation, and even the uniformly looking tropical rain forests are a mosaic of different habitats depending on the soils, the regional climate and also the geological history. An important part of the nutrient webs of the rain forests is formed by the terrestrial Isopoda, or Oniscidea, the only truly terrestrial taxon within the Crustacea. They are important, because they participate in soil formation by breaking up leaf litter when foraging on the fungi and bacteria growing on them. After a century of research on this interesting taxon, a revision of the terrestrial isopod taxa from South America and some of the Antillean Islands, which are traditionally placed in the family Philosciidae, was performed in the last years to establish monophyletic genera. Within this study, the phylogenetic relationships of these genera are elucidated in the light of phylogenetic systematics. Several new taxa are recognized, which are partially neotropical, partially also found on other continents, particularly the old Gondwanian fragments. The monophyla are checked for their distributional patterns which are compared with those patterns from other taxa from South America and some correspondence was found. The distributional patterns are analysed with respect to the evolution of the Oniscidea and also with respect to the geological history of their habitats. -

--- Not for reuse or distribution --- 8 HERMAPHRODITISM AND GONOCHORISM Chiara Benvenuto and Stephen C. Weeks Abstract This chapter compares two sexual systems: hermaphroditism (each individual can produce gametes of either sex) and gonochorism (each individual produces gametes of only one of the two distinct sexes) in crustaceans. These two main sexual systems contain a variety of alternative modes of reproduction, which are of great interest from applied and theoretical perspectives. The chapter focuses on the description, prevalence, analysis, and interpretation of these sexual systems, centering on their evolutionary transitions. The ecological correlates of each reproduc- tive system are also explored. In particular, the prevalence of “unusual” (non- gonochoristic) re- productive strategies has been identified under low population densities and in unpredictable/ unstable environments, often linked to specific habitats or lifestyles (such as parasitism) and in colonizing species. Finally, population- level consequences of some sexual systems are consid- ered, especially in terms of sex ratios. The chapter aims to provide a broad and extensive overview of the evolution, adaptation, ecological constraints, and implications of the various reproductive modes in this extraordinarily successful group of organisms. INTRODUCTION 1 Historical Overview of the Study of Crustacean Reproduction Crustaceans are a very large and extraordinarily diverse group of mainly aquatic organisms, which play important roles in many ecosystems and are economically important. Thus, it is not surprising that numerous studies focus on their reproductive biology. However, these reviews mainly target specific groups such as decapods (Sagi et al. 1997, Chiba 2007, Mente 2008, Asakura 2009), caridean Reproductive Biology. Edited by Rickey D.

E-mail: [email protected] Abstract Trichomycterus trefauti, new species, is described based on eight specimens from the rio São Fran- cisco basin, Minas Gerais, Brazil. The new species differs from all other trichomycterine species by the autapomorphic presence of an elliptical, vertically elongated, brown spot, at caudal-fin base, and the combination of homogeneously gray color pattern, first pectoral-fin ray prolonged as a fila- ment, subterminal mouth, two supraorbital pores at interorbital space, caudal fin truncate with attenuated edges, pelvic fins covering anus and urogenital openings, interorbital space very wide (39.8–45.9 % head length), maxillary barbels very long (84.2–93.0 % head length), rictal barbels very long (67.6– 74.3 % head length). Systematics, diagnostic features, and putative information on phylogenetic relationships of Trichomycterus species are discussed.

A New Species of Cave Catfish, Genus Trichomycterus (Siluriformes: Trichomycteridae), from the Magdalena River System, Cordillera Oriental, Colombia
Castellanos-Morales A new species of cave catfish, genus Trichomycterus (Siluriformes: Trichomycteridae), from the Magdalena River system, Cordillera Oriental, Colombia A new species of cave catfish, genusTrichomycterus (Siluriformes: Trichomycteridae), from the Magdalena River system, Cordillera Oriental, Colombia Una nueva especie de bagre de caverna, género Trichomycterus (Siluriformes: Trichomycteridae), del sistema río Magdalena, cordillera Oriental, Colombia César A. Castellanos-Morales Abstract A new species of troglomorphic catfish is described from de Gedania Cave, located in the middle Suárez River drainage, Magdalena River system, Colombia. The new species can be distinguished from its congeners by the combination of the following characters: reduction or loss of the cornea, reduction of eyes and skin pigmentation, very long nasal and maxillary barbels (maximum of 160% and 135% of HL, respectively), nine branched pectoral-fin rays, first unbranched ray of the pectoral fin prolonged as a long filament, reaching 80% of pectoral-fin length, anterior cranial fontanel connected with the posterior fontanel through an opening of variable length and width, first dorsal- fin pterygiophore inserted between neural spines of free vertebra 13-14 and free vertebrae 33-34. The presence of troglomorphisms such as regression of the eyes, reduction of skin pigmentation and long barbels suggest the troglobitic status of this species. A comparative analysis with other species of Trichomycterus from epigean and hypogean environments is presented. -

A New Species of the Neotropical Catfish Genus Trichomycterus (Siluriformes: Trichomycteridae) Representing a New Body Shape for the Family
Copeia 2008, No. 2, 273–278 A New Species of the Neotropical Catfish Genus Trichomycterus (Siluriformes: Trichomycteridae) Representing a New Body Shape for the Family Wolmar Benjamin Wosiacki1 and Ma´rio de Pinna2 Trichomycterus crassicaudatus is described as a new species from the Rio Iguac¸u basin in southern Brazil. The new species has an exceptionally deep posterior region of the body (caudal peduncle depth 22.8–25.4% SL), resulting in an overall shape which distinguishes it at once from all other members of the Trichomycteridae. The caudal fin of the species is broad-based and forked, a shape also distinguishing it from all other species in the family. A number of autapomorphic modifications of T. crassicaudatus are associated with the deepening of the caudal region, including an elongation of the hemal and neural spines of the vertebrae at the middle of the caudal peduncle. Phylogenetic relationships of the new species are yet unresolved, but it shares a similar color pattern and a thickening of caudal-fin procurrent rays with T. stawiarski, a poorly-known species also from the Rio Iguac¸u basin. Coloration and body shape also include similarities with T. lewi from Venezuela. HE genus Trichomycterus is the largest in the the ninth species of Trichomycterus recorded for the Rio family Trichomycteridae, with approximately 100 Iguac¸u Basin above the Iguac¸u waterfalls (the others being T. T nominal species and probably numerous others stawiarski, T. castroi, T. naipi, T. papilliferus, T. mboycy, T. still undescribed. The genus is not demonstrably a mono- taroba, T. plumbeus, and T. -

The Blind Catfish from the Caves of Chapada Diamantina
Neotropical Ichthyology, 8(4):673-706, 2010 Copyright © 2010 Sociedade Brasileira de Ictiologia The blind catfish from the caves of Chapada Diamantina, Bahia, Brazil (Siluriformes: Heptapteridae): description, anatomy, phylogenetic relationships, natural history, and biogeography Flávio A. Bockmann and Ricardo M. C. Castro Rhamdiopsis krugi, a new troglobitic heptapterid catfish, is described from the caves of Chapada Diamantina, State of Bahia, northeastern Brazil. This species, although frequently cited in the scientific literature along the last seventeen years, remained undescribed largely due to its uncertain phylogenetic affinities. The generic assignment of R. krugi was clouded largely by its high number of unusual morphological features (some related to cave life), for instance: absence of eyes and body pigmentation; presence of a widely exposed pseudotympanum; posterior border of the anterior branch and anterior margin of the arborescent portion of the posterior branch of the transverse process of fourth vertebra joined; dorsal hypural plate commonly with seven rays; ventral caudal plate usually with six rays; dorsal and ventral caudal-fin lobes typically with six branched fin rays each; 38- 39 vertebrae; anal fin with 14-17 rays; and lateral line very short. Rhamdiopsis krugi can be easily distinguished from its congeners, R. microcephala and R. moreirai, by its troglomorphic features and by the presence of a shorter lateral line, fewer vertebrae and anal-fin rays, pattern of branching of caudal-fin rays, and several attributes of skeletal system. The affinities of this new species are discussed in light of current phylogenetic knowledge of the family Heptapteridae. Incongruent derived characters do not allow selection of a particular hypothesis of sister group relationships among species of Rhamdiopsis. -
