Taxonomy of the water beetle genus Limnebius Leach in southern Africa (Coleoptera: Hydraenidae).
نویسنده
چکیده
The southern African species of the water beetle genus Limnebius Leach, 1815, are revised. Eleven new species are described, based on the examination and databasing of 6,201 specimens from 96 localities/events. Male genitalia are illustrated, and high resolution habitus images of the holotypes are provided. Distribution maps are provided for the eleven species now known from southern Africa, including Namibia, South Africa, Zambia, Zimbabwe, and the extreme southern part of Angola. New species of Limnebius are: L. capensis (South Africa: Western Cape Province, W. Cape, Hawequas); L. convexus (South Africa: Western Cape Province, Little Karroo, Raubenheimer Dam); L. endroedyi (Namibia: C. Namib desert, Numis Wasser); L. kavango (Namibia: Kavango: Mahango Game Reserve); L. masculinus (South Africa: KwaZulu-Natal Province, Hluhluwe Game Reserve); L. probus (South Africa: KwaZulu-Natal Province, Zululand, Dukuduku Forest Station); L. quantillus (South Africa: Limpopo Province, N. Transvaal, Mmabolela estate); L. retiolus (South Africa: Northern Cape Province, Cape Farm Ezelsfontein); L. speculus (South Africa: KwaZulu-Natal Province, Hluhluwe Game Reserve); L. suaviculus (South Africa: KwaZulu-Natal Province, Tugela River near Olivershoek road); L. transversus (South Africa: KwaZulu-Natal Province, Mtubatuba).

Evolution of the male genitalia in the genus Limnebius Leach, 1815 (Coleoptera, Hydraenidae)
We investigated the evolution of the male genitalia of species of Limnebius (Coleoptera, Hydraenidae). This genus is very homogeneous externally but characterized by highly diverse male genitalia, which are in some cases extraordinarily complex. We reconstructed a molecular phylogeny for 70 of the c. 150 known species of the genus with six fragments of mitochondrial and nuclear genes. We found ...

Hydraena Kugelann represents the largest genus within the water beetle family Hydraenidae, and in particular within Hydraeninae, with about 900 species widely distributed all over the world and several hundreds not yet described. In a recent cladistic analysis, based on morphological characters, Hydraena s. l. was split into two subgenera: Hydraenopsis Janssens (Gondwanian) and Hydraena s. str....

The southern African species of the water beetle genus Hydraena Kugelann, 1794, are revised. Twenty-eight new species are described, and redescriptions and new collection records are given for three previously described species, based on the examination and databasing of 11,534 specimens from 488 localities/events. Male genitalia are illustrated, and high resolution habitus images of the holoty...
متن کاملEvolution of sexual dimorphism and Rensch’s rule in the beetle genus Limnebius (Hydraenidae): is sexual selection opportunistic?
Sexual size dimorphism (SSD) is widespread among animals, with larger females usually attributed to an optimization of resources in reproduction and larger males to sexual selection. A general pattern in the evolution of SSD is Rensch's rule, which states that SSD increases with body size in species with larger males but decreases when females are larger. We studied the evolution of SSD in the ...
