The genital fields of Canuella Perplexa and C. Furcigera (Copepoda, Harpacticoida) – comparative morphology and functional aspects
Provedor de dados: 16
Autores: Glatzel, Thomas.
The harpacticoids Canuella perplexa T. &amp; A. Scott, 1893 and Canuella furcigera Sars, 1903 differ not only in size and length of the furca, but above all in the structure of the genital fields in both sexes. These differences, which have not been described exactly so far, are demonstrated by SEM micrographs and by drawings. Since there is no adequate terminology for the description of genital fields, terms are introduced in this study. A partly extruded spermatophore in a male specimen of Canuella perplexa is shown by a SEM micrograph. Mating has never been observed in either species; however, from the anatomical structure some conclusions may be drawn on the possible configuration of the genital fields during mating.

Mating behaviour of the groundwater copepod Parastenocaris phyllura Kiefer, 1938 (Copepoda: Harpacticoida)
Provedor de dados: 16
Autores: Glatzel, Thomas; Schminke, Horst Kurt.
In the course of a cohort study of Parastenocaris phyllura several matings were observed under a microscope and recorded on video. In Parastenocaris phyllura no “precopulatory mate guarding” was found. Each mating behaviour comprises three phases and lasts for about 15 minutes, during which time the male actively moves its antennulae and antennae, pereiopods 1, 2, 3, 4, and furcal rami. The female is held in a characteristic position by the male and is entirely passive during the process.

Beschreibung der sechs Nauplius-Stadien von Parastenocaris phyllura Kiefer, 1938 im Vergleich mit P. vicesima Klie, 1935 (Copepoda, Harpacticoida)
Provedor de dados: 16
Autores: Glatzel, Thomas.
Six non-overlapping size classes and morphologically distinct nauplius stages of Parastenocaris phyllura are studied using light microscopy. The nauplii have been reared in laboratory cultures. A comparative analysis of the morphology of the nauplius stages of P. phyllura and P. vicesima (cf. Schminke, 1982) is presented.
