Última A new species of Stratiodrilus (Polychaeta, Histriobdellidae) from freshwater crayfishes of southern Brazil Iheringia, Sér. Zool. Amato,J. F. R.. A new species of polychaete, Stratiodrilus vilae, epizoic on Parastacus brasiliensis (von Martens, 1869) and P. defossus Faxon, 1898, is described from the State of Rio Grande do Sul, southern Brazil. The new species has one pair of long, anal, conical ventral lobes, one on each side of the anus, claspers in the males, and one pair of tubercles in each of the posterior locomotor appendages; and the jaw apparatus not reaching the limit between the head and the first segment.

New Guinea), Indonesia (Crustacea: Decapoda: Parastacidae) Naturalis Holthuis, L.B.. A new species of parastacid crayfish, Cherax (Astaconephrops) minor is described from the central mountains of Irian Jaya (West New Guinea), Indonesia. Its small size distinguishes it from most other New Guinea crayfishes.

Ano: 1996 URL: http://www.repository.naturalis.nl/record/318294 Aspectos anatômicos e funcionais do aparelho reprodutor de Parastacus brasiliensis (von Martens) (Crustacea, Decapoda, Parastacidae) Zoologia Almeida,Alexandre Oliveira de; Buckup,Ludwig. The absence of morphological external characteristics that allow the recognition of the sex as well as the presence of both male and female gonopores in the same animal [except in some sexual forms of Parastacus nicoleti (Philippi, 1882)] gives rise to the hypothetical existence of some form of hermaphroditism in crayfishes belonging to the genus Parastacus Huxley, 1879. Specimens of Parastacus brasiliensis (von Martens, 1869) were collected in a rivulet at Mariana Pimentel municipality, Rio Grande do Sul, Brazil. In the laboratory they were reared and dissected. The results suggest that P. brasiliensis may be a sequential hermaphroditic species, but male and female gonadal tissues were not simultaneously present in the analized samples. In testes and...
