The current distribution (2009) and survey methodologies are provided for detecting the Coachella Valley Jerusalem Cricket (Stenopelmatus cahuilaensis Tinkham 1968). When several survey methodologies are assessed, we found that, in the absence of debris, the use of cover-boards and the examination of areas beneath cow manure pats (cow chips) to be the most efficient and least destructive ways of detecting this rare and unique desert species. When using these methods we were able to establish the current distribution of the insect and compare it to historical records. The present distribution of the cricket suggests that it is currently undergoing a westward movement in its range as well as an overall range contraction possibly as a result of climate change.

Xylanura oregonensis, a new genus and species of Neanurini from North America is described and illustrated. The new species is a saproxylic form, living in rotting wood and under bark of decaying logs of deciduous trees. Taxonomic remarks and an identification key to the world genera of Neanurini are provided.

We review the distribution of the water scavenger beetles (Hydrophilidae) in the northern part of Tunisia, based on data from 54 sites collected over the course of a year. In total, 21 hydrophilid species were found. The most interesting ones from the zoogeographical point of view are: Enochrus nigritus Sharp, 1872, Enochrus affinis Thunberg, 1794, Laccobius revelierei Perris, 1864 (all newly recorded for Tunisia), and Laccobius orientalis Knisch, 1924 and Berosus spinosus Steven, 1808 (newly recorded for northern Africa). An updated checklist of hydrophilid species occurring in the northern Tunisia is provided. The composition of the hydrophilid fauna in the area is assessed using the indexes of richness, abundance and diversity. We discuss possible causes of this phenomenon; identify the most valuable water beetle habitats within the investigated area that should be protected by law.

Melanesiandra barclayi, a new species of Parandrini (Parandrinae) from Guadalcanal Island (Solomon Islands) is described and illustrated. A key is presented to separate the five known species of the genus.
