We tested the effect of a large ungulate carcass on boreal forest biodiversity by contrasting the local abundance and diversity of Coleoptera around a roe deer Capreolus capreolus carcass and in a control plot, between 8 August and 3 September 2003, in southern Norway. The two plots differed both in occurrence and richness of species, which were almost double at the carcass plot, although the diversity indices were similar. The higher evenness of the control plot compensated for its lower number of species, probably because the carcass plot was a disturbed area, colonized by many species, which were represented by few individuals. The number of beetles captured each day correlated positively with temperature at the control plot, but not at the carcass plot, indicating that the presence of an abundant and concentrated resource increased the local activity of Coleoptera. The carcass is likely to create a particular microclimate, which could partly buffer against extremes of air-temperature variation. These preliminary results indicate that ungulate carcasses have a significant ecological impact, which should be further investigated to improve the management and restoration of European boreal forest ecosystems.

The types of some Xantholinini (Coleoptera, Staphylinidae) from China are studied. The sixth male visible abdominal scgment, genital segment and aedeagus are illustrated for the first time for Nepalinus parcipennis (Bernhauer), Hypnogyrn hoff' rnanni (Bernhauer), Xantholinus semipallidus (Bernhauer); genital segment and aedeagus are illustrated also for Nrrdobius nigrivenrris Zheng and Cyrohypnus sichuanensis Zheng. The following new species are described: Stenistoderiis sinicus n. sp. (Hopeh, Hebei, Shaanxi), Leptacinus harbinensis n. sp. (Harbin), Cyrohypnus wutaishanensis n. sp. (Shaanxi), LepidophnNirs boki n. sp. (Shaanxi, Sichuan, Guizhou, Yunnan, Zhejiang, Hangzhou). Two new combinations are proposed: Hypnogprrr huffnzunni (Bernhauer) and Nepalinus parcipennis (Bernhauer).

Milichilinus Reitter, 1908, described as a subgenus of Xantholinus Dejean, 1821, is elevated to the status of genus on the basis of some external characters and an aedeagus with large parameres. The genus currently includes Milichilinus decorus (Erichson, 1839), comb. nov., and Milichilinus meybohmi (Assing, 2006), comb. nov. Lepidophallus denticulatus Bordoni, 2004 is recorded as new from Bulgaria. The following replacement names are proposed: Echdysia, nom. nov., Edulia, nom. nov., Emathidis, nom. nov. for the preoccupied Elgonia Bordoni, 2001, Lepta Bordoni, 2002 and Cibyra Bordoni, 2002, respectively. The holotype of Lepidophallus bicatellatus Bordoni, 2005 is preserved in Schülke collection in Berlin.

Length of body 3.7 mm; from anterior margin of head to posterior margin of elytra: 2.1 mm. Body shiny, entirely light brown; antennae and legs yellowishbrown. Head quadrangular. Eyes large and protruding. Surface of head with traces of transverse micro-striation and very few, isolated punctures. Pronotum longer than head, anteriorly a little dilated where it is as wide as head, with oblique anterior margins and rounded sides. Surface with dorsal series of 3-4 fine punctures and lateral series of 2-3 very fine punctures. Elytra sub-rectangular, longer and a little wider than pronotum, with sub-rectilinear an sub-parallel sides, and rounded humeral angles. Surface with very fine, sparse puncturation arranged in three series, one near the suture, one median and one lateral. Abdomen without micro-sculpture, with very fine and very sparse puncturation on the sides. Tergite and sternite of the male genital segment as in Figs 3-4. Aedeagus (Fig. 5) 0.74 mm long, with large median lobe; parameres long and narrow; inner sac with two basal, long spines, a median series of short, little spinulae and a group of distal spines.

This paper studies the taxonomy of the genus Megalinus Mulsant & Rey, 1877 (Coleoptera: Staphylinidae, Xantholinini) and offers a comprehensive revision of the Chinese fauna. Seven new species are described: Megalinus ailaoshanensis Zhou & Zhou sp. nov. from Yunnan, M. hailuogouensis Bordoni sp. nov. from Sichuan, M. liupanshanensis Zhou & Zhou sp. nov. from Ningxia, M. ningxiaensis Bordoni sp. nov. from Ningxia, M. nonvaricosus Zhou & Zhou sp. nov. from Ningxia, M. solidus Zhou & Zhou sp. nov. from Hainan and Yunnan, and M. tangi Bordoni sp. nov. from Xizang. The taxonomic status of M. leishanensis (Bordoni, 2007) is reinstated and treated as a valid species here. The following new synonym is proposed: M. suffusus (Sharp, 1874) = L. flavoelytratus (Bordoni, 2007) syn. nov. Three species originally described in Chinese are redescribed here: M. cinnamomeus (Zheng, 1994), M. coracinus (Zheng, 1994) and M. zhenyuanensis (Zheng, 1994). Therefore the Chinese fauna of the genus Megalinus is now represented by a total of 33 species. A key to all Chinese species is provided.
