An illustrated key to the Afrotropical bark beetle species of Cladoctonus Strohmeyer (Curculionidae, Scolytinae)-a genus of rare cossonine look-alikes.

The Afrotropical species of Cladoctonus Strohmeyer, 1911 is revised. A key to species is provided with all species illustrated with photos. Five species are currently recognized as valid.

An integrated taxonomic revision of (Coleoptera, Curculionidae, Scolytinae) reveals new Malagasy species originating from multiple recent colonisations of the island.

is a strictly Afrotropical genus of bark beetles breeding under bark of rainforest trees and lianas. A taxonomic revision of the genus included a molecular phylogenetic analysis of ten species based on three gene fragments and was compared to a morphology-based tree topology for all 24 currently recognised species. Four species are described as new to science: , , , , , , all from Madagascar, and , from Cameroon.

The systematic status of Sellnick, 1928, is not clear in the literature. Therefore, the morphological ontogeny of . (C.

An illustrated key and new records of the Afrotropical bark beetle genus Cryphalomimus Eggers (Coleoptera, Curculionidae).

The Afrotropical genus Cryphalomimus Eggers, 1927 is revised. New distributional records are added, showing a broad but scattered distribution of C. striatus Eggers, 1927.

Two sympatric lineages of Australian Cnestus solidus share Ambrosiella symbionts but not Wolbachia.

Sympatric lineages of inbreeding species provide an excellent opportunity to investigate species divergence patterns and processes. Many ambrosia beetle lineages (Curculionidae: Scolytinae) reproduce by predominant inbreeding through sib mating in nests excavated in woody plant parts wherein they cultivate symbiotic ambrosia fungi as their sole source of nutrition. The Xyleborini ambrosia beetle species Cnestus solidus and Cnestus pseudosolidus are sympatrically distributed across eastern Australia and have overlapping morphological variation.
