Distinct copulation positions in Drosophila pachea males with symmetric or asymmetric external genitalia: erratum
Provedor de dados: Naturalis Digital Academic Repository
Autores: Lang, M.; Orgogozo, V.
Left-right asymmetric genitalia have appeared multiple times independently in insects and have been associated with changes in mating positions. However, there is little experimental data on how the evolution of genital asymmetries may have affected the evolution of mating positions or vice versa. As opposed to its closely-related species, Drosophila pachea has a conspicuous asymmetry in its male genitalia external lobes, with the left lobe being 1.49 ± 0.08 (SD) times longer and thinner than the right lobe. In a laboratory stock, we found that 20% of the males possess fully symmetric lobes. To better understand how asymmetric genitalia may affect mating, we compared D. pachea copulation behaviour between these mutant males and wildtype males. We found...

Mating behaviour of the groundwater copepod Parastenocaris phyllura Kiefer, 1938 (Copepoda: Harpacticoida)
Provedor de dados: Naturalis Digital Academic Repository
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.

Precopulatory mate guarding in copepods
Provedor de dados: Naturalis Digital Academic Repository
Autores: Boxshall, Geoffrey A.
In many copepod species adult males clasp females for an extended period before transferring spermatophores. Clasping juvenile females (first to fifth copepodid inclusive) is interpreted as mate guarding and is shown to be widespread among podoplean copepods. It is distinct from copulation, which takes place only between adults and is often distinguishable from mate guarding by a difference in clasping posture.
