Comparative larval ultramorphology of three endemic Lathrobium (Glyptomerus) species (Coleoptera, Staphylinidae, Paederinae) from the Eastern Alps in Italy.

The paper describes the mature larvae (L2) of Lathrobium alzonai, L. freyi and L. paceiendemic, depigmented, apterous and subanophthalmous rove beetles from the Eastern Alps in Italy (Coleoptera: Staphylinidae; Paederine)belonging to the subgenus Glyptomerus. The larva of Lathrobium pacei Piva, 1994 is described for the first time, whereas the larvae of L. alzonai Capra Binaghi, 1938 and L. freyi Koch, 1938 are redescribed. Detailed illustrations of their structural features are provided, and diagnostic larval - morphological characters for Lathrobium are proposed. Based on earlier published and new data, morphological comparisons, both intergeneric (between Lathrobium and Tetartopeus) and interspecific (between L. alzonai, L. freyi and L. pacei) within the subtribe Lathrobiina, are made. The principal differences among the genera and species involve particular structures of the head and their measurements. The generic status of Tetartopeus was confirmed. No clear differences in the external morphological structure between the larvae of Glyptomerus and Lathrobium s.str. were noted. The morphological structure of L. alzonai larvae differed significantly from that of the larvae of the other two species. The differences relate mainly to the much larger body size of L. alzonai, the shape of the head with its relatively narrow neck, the details of the mouthparts structure and the distinct elongation of its antennae, maxillary palps, labial palps, some parts of the legs and urogomphi. Distribution of all known Italian glyptomeroid species of the genus Lathrobium is also given.

Two new species of Metapocyrtus (Metapocyrtus) Heller 1912 from Mindanao, Philippines (Curculionidae, Entiminae, Pachyrhynchini).

Two new species of Curculionidae, Pachyrhynchini, Metapocyrtus waoensis sp. nov., and M. lanaoensis sp. nov., both from western Mindanao are described. Images of habitus and fully everted endophallus and illustrations of male genitalia are provided for each species.

Description of Neoxantholinus koghianus sp. n. and its larva from New Caledonia (Coleoptera, Staphylinidae, Xantholinini).

Neoxantholinus koghianus sp. n. (Coleoptera, Staphylinidae, Xantholinini) and the detailed external structure of its late (L2-3) and early (L1) larval instars from New Caledonia are described and illustrated. The morphological differences between L1 and L2-3 of N. koghianus sp. n. involve four characters. Diagnostic larval characters for the genus Neoxantholinus are given for the first time.

Revision of the genus Thyreocephalus and description of Afrus gen. nov. of Africa south of the Sahara (Coleoptera: Staphylinidae: Staphylininae).

A revision of the genus Thyreocephalus Guérin-Méneville, 1844 of Africa south of the Sahara is presented. A new genus Afrus gen. nov. was described with the type species Thyreocephalus spegazzinii Bernhauer, 1915, which resulted in following new combination: Afrus spegazzinii (Bernhauer, 1915), comb. nov. Eulissus collarti (Cameron, 1932) was transferred to Afrus. Based on a revision of types and of additional material, 32 species of the genus Thyreocephalus and two species of the genus Afrus are recognized in Africa south of the Sahara. All species are described or redescribed and illustrated, seven of them for the first time: Thyreocephalus camerunensis sp. nov., T. manfredi sp. nov., T. marginipennis sp. nov., T. meridioafricanus sp. nov., T. pseudoafricanus sp. nov., T. subcorticalis sp. nov. and T. tsingidianus sp. nov. Neotypes are designated for Eulissus ater Laporte, 1835, Xantholinus coeruleipennis Quedenfeldt, 1881, and X. interocularis Eppelsheim, 1895. Lectotypes are designated for Eulissus atlanticus Bernhauer, 1915, E. burgeoni Bernhauer, 1929, E. mokaensis Bernhauer, 1915, E. secretus Bernhauer, 1935, E. turneri Bernhauer, 1937, Xantholinus alluaudi Fauvel, 1907, X. mocquerysi Fauvel, 1903, X. pilosus Roth, 1851, Thyreocephalus diversiceps Bernhauer, 1936, and T. spegazzinii Bernhauer, 1915. Eulissus africanus Bernhauer, 1913, E. alluaudi (Fauvel, 1907) (originally described in Xantholinus Dejean, 1821), E. atlanticus Bernhauer, 1915, E. brunneiventris Tottenham, 1956, E. burgeoni Bernhauer, 1929, E. guineensis Bernhauer, 1912, E. mokaensis Bernhauer, 1915, E. secretus Bernhauer, 1935, E. strinatii Scheerpeltz, 1958, and Xantholinus nairobiensis Fauvel, 1907 were transferred to Thyreocephalus. Following synonymies are proposed: Thyreocephalus nairobiensis (Fauvel, 1907) = Eulissus turneri Bernhauer, 1937, syn. nov., Thyreocephalus interocularis (Eppelsheim, 1895) = Thyreocephalus diversiceps Bernhauer, 1936, syn. nov., Thyreocephalus mokaensis (Bernhauer, 1915) = Eulissus flaviventris Bernhauer, 1939, syn. nov. = Thyreocephalus semirufus Coiffait, 1968, syn. nov., Thyreocephalus mocquerysi (Fauvel, 1903) = Eulissus milliaui Bernhauer, 1932, syn. nov. The distribution of both genera in Africa south of Sahara is mapped and a key to species is presented.

Revision of the genus Achmonia of Africa south of the Sahara (Coleoptera: Staphylinidae: Staphylininae).

A redescription of the genus Achmonia Bordoni, 2004 is presented. Based on a revision of types and of additional material, seven species are recognized in Africa south of the Sahara and placed into two species groups. All species are described or redescribed and illustrated, four of them for the first time: Achmonia carinata sp. nov., A. kapangana sp. nov., A. knirschi sp. nov., and A. simulator sp. nov. A lectotype is designated for Xantholinus amabilis Boheman, 1848, Eulissus flavomarginatus Bernhauer, 1929 and E. congoensis Bernhauer, 1932. These species are transferred to Achmonia. A lectotype is designated for Eulissus semiflavus Bernhauer, 1913, and E. gerardi Bernhauer, 1929 and the following synonymy is proposed: Achmonia amabilis (Boheman, 1848) = Eulissus semiflavus Bernhauer, 1913, syn. nov. = Eulissus gerardi Bernhauer, 1929, syn. nov. The distribution of the genus in Africa south of Sahara is mapped and a key to species is presented.

Taxonomy of the genus Megalinus Mulsant & Rey (Coleoptera: Staphylinidae, Xantholinini) and seven new species from China.

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) andM. 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.
