A New Species

Yara marmontsedu, a new species in the family Hydroscaphidae (Coleoptera: Myxophaga), is described and illustrated. Specimens of Y. marmontsedu were collected at the Pijibay Creek, tributary of the Mico River in Chontales, Nicaragua. The immature stages are described and illustrated for the first time for a species of Yara. This is a contribution to the knowledge of the water beetle fauna of Nicaragua.

Nw Poland

<p>Using the example of a regulated stretch of the Krąpiel River (NW Poland), an analysis of the impact of dredging on the aquatic beetle (Coleoptera) fauna was made. After dredging the beetle fauna became markedly poorer quantitatively and had lower species diversity. Moreover, the qualitative composition and dominance structure were highly transformed. However, species number and diversity increased rapidly and were restored within just half a year. The structure of the restored fauna was most strongly influenced by vegetation, flow velocity and bottom sediment composition. The first to colonize the river were eurytopic beetles and species typical of small water bodies, which had significant refuges in the form of fish ponds bordering on the river; these species dominated the assemblage throughout the study period. Rheophiles with less dispersal power appeared later, and finally rheobionts, in low numbers but occupying an increasing number of sampling sites. </p>
