Structure and topology of microbial communities in the major gut compartments of Melolontha melolontha larvae (Coleoptera: Scarabaeidae).

Physicochemical gut conditions and the composition and topology of the intestinal microbiota in the major gut compartments of the root-feeding larva of the European cockchafer (Melolontha melolontha) were studied. Axial and radial profiles of pH, O2, H2, and redox potential were measured with microsensors. Terminal restriction fragment length polymorphism (T-RFLP) analysis of bacterial 16S rRNA...

One the genus Tocama Reitter (Coleoptera, Scarabaeidae, Melolonthinae), with descriptions of two new species from Indochina

Two new species of the Oriental scarab genus Tocama Reitter, 1902, Tocama laosensissp. n. and Tocama procerasp. n., are described from Indochina with diagnoses, distributions, remarks and illustrations. A key to the species of the genus is provided with a checklist with several nomenclatural changes: Hoplosternus tonkinensis Moser, 1913 is transferred to Tocama; Hoplosternus pygidialis Moser, 1...

Indirect closing of the elytra in a cockchafer, Melolontha hippocastani F. (Coleoptera: Scarabaeidae).

Actuation of the closing of the elytra was previously ascribed to intrinsic muscles in the mesothorax. We investigated closing (1) by loading or arrest of some thoracic segments in a tethered flying beetle, (2) by animation, i.e. passive motion of preparations of the thorax simulating the action of some muscle, and (3) by excision of some parts of sclerites or cuts across certain muscles. We fo...

Review of the genera Anelaphinis Kolbe, 1892 and Atrichelaphinis Kraatz, 1898 (Coleoptera, Scarabaeidae, Cetoniinae)

New material collected recently throughout the Afrotropical region has led to a major reassessment of taxa within the genera Anelaphinis Kolbe, 1892, Atrichelaphinis Kraatz, 1898 and other closely related genera. As a result, the name Megalleucosma Antoine, 1989 is here synonymised with Anelaphinis and a lectotype is designated for the type species, Cetoniadominula Harold, 1879. The genus Atric...
