Fossil elytra of a small trechine carabid are reported from the Oliver Bluffs on the Beardmore Glacier at lat. 85°S.

The subulate apical palpomeres and other characters place this new genus in Bembidiini and the sub-oblique notched anterior tibiae assign it to the...

Evolutionary theory predicts that both the virulence and the sex ratio of a parasite can depend upon its population structure, and be positively correlated. With only one or a low number of strains within a host, a low sex ratio and a relatively low virulence are predicted. With high numbers of strains within a host, a more even sex ratio and a high parasite virulence are predicted. We examined...

Two species, Hymenorus bifurcatus, and H. excavatus are described as new from Guatemala and the new species H. balli from both the state of Chiapas in southern Mexico and Guatemala. These three species are unique among the species of Hymenorus Mulsant, 1851 in the unusual and highly modified fifth ventrites of the male and the modified shape of the female ninth tergites. The unusual sexual char...
