THE GENUS Metabetaeus was describ ed by Borradaile (1898 : 1014) to contain the species originally describ ed by Whitelegge ( 1897: 147 ) as Betaeus minutus. These descriptions and Couriere's subsequent discussion of the genus ( 1899: 374 ) were all based on a series of specimens collected at Funafuti in the Ellice Arch ipelago. Nothing more on either the genus or the species was recorded until...

The Mediterranean orthotyline genus Platycranus is revised. Updated diagnoses and descriptions, data on distribution and hosts are provided for the genus and included species, and a key is presented to facilitate identification of species. Pictures of the dorsal habitus, scanning electron micrographs, and figures of genital structures are given. The following new synonymies are established: P. ...

According to theory, directional female choice for male sexual ornaments is expected to erode underlying genetic variation. Considerable attention, in this regard, has been given to understanding the ubiquity of heritable genetic variation in both female choice and male sexual traits. One intriguing possibility emerging from this work is that persistent genetic variation could be maintained, ov...

In this study, we present phylogenetic data to characterize the relationships among sironids centered in the Balkan region, and use these results to discuss biogeographical aspects of sironid evolution. Analysis of ca. 4.5 kb of sequence data from three nuclear and two mitochondrial genes reveals monophyly of a Balkan clade for which we resurrect the name Cyphophthalmus, considered a junior syn...
