A Comparative Study of Copulation in Passalidae (coleoptera): New Positions for Beetles
نویسندگان
چکیده
Copulation, observed in 6 species of Passalidae, occurred with one beetle up-side-down in relation to the other. In Odontotaenius they were end to end (known for Coleoptera only in Scolytidae); in Passalus they were venter to venter facing nearly the same direction (known for no other beetles and only for certain Diptera and Mecoptera among other insects).

We examined log-inhabiting arthropods and their associated mites for ectoparasitic fungi (Ascomycetes: Laboulbeniales) in South-east Queensland and Far North Queensland. Fungus host records were: Rickia berlesiana (Baccarini) on most species of Fedrizziidae (Acari: Mesostigmata) and three species of Passalidae (Coleoptera); Rickia leptaulacis Thaxter on two species of Fedrizzia (Fedrizziidae), ...

Yumtaax Boucher (Coleoptera: Passalidae) is an endemic genus from the temperate sierras of Mexico and includes six narrowly distributed species. Yumtaax species have been assigned to several genera of Passalidae throughout history, and a phylogenetic approach is necessary to understand species delimitation and interspecific relationships. This study reconstructed the molecular phylogeny of six ...

The faunistic investigation of beetles has been of a great importance in Iran due to the impresive diversity of species, which is highly promoted by the climatic variation of the Country. Therefore, detection of the ingenious regions, such as Taleqan, is important. In this study, mite-related beetles which were sampled from different areas of Taleqan were investigated and 14 species belonging t...
