Wewalka, G. 2000. Taxonomic revision of Allopachria (Coleoptera: Dytiscidae). Entomol. Probl. 31(2): 97-128.

The dytiscid genus Allopachria Zimmermann is revised taxonomically. Twenty-five new species are described: A. abnormipenis sp.nov. [Borneo], A. balkei sp.nov. [Borneo], A. beeri sp.nov. [Vietnam], A. dieterlei sp.nov. [China], A. dudgeoni sp.nov. [China], A. ernsti sp.nov. [Vietnam], A. friedrichi sp.nov. [China], A. froehlichi sp.nov. [China], A. guidettii sp.nov. [Thailand], A. hautmanni sp.nov. [China], A. hendrichi sp.nov. [Java], A. holmeni sp.nov. [Thailand], A. jaechi sp.nov. [China], A. jendeki sp.nov. [China], A. jilanzhui sp.nov. [China], A. kodadai sp.nov. [Borneo], A. liselotteae sp.nov. [China], A. sausai sp.nov. [Vietnam], A. schillhammeri sp.nov. [China], A. schoenmanni sp.nov. [China], A. scholzi sp.nov. [China], A. schramhauseri sp.nov. [Thailand], A. shepardi sp.nov. [Thailand], A. weinbergeri sp.nov. [China], and A. zetteli [Borneo]. Allopachria barong Hendrich, Balke & Wewalka is transferred to Agnoshydrus, A. ullrichi Balke & Hendrich will be assigned to a new genus and A. umbrosa Zimmemann known to author only from the description is excluded because it probably belongs to an other genus. Neotypes are designated for A. quadripustulata Zimmermann and A. flavomaculata (Kamiya) and a key to the 32 species of the genus Allopachria currently known until now is given.

Kodada, J. & Boukal, D.S. 2000. Monstrosostea solivaga new genus and species of aberrant terrestrial dryopid from southern India (Coleoptera: Dryopidae). Entomol. Probl. 31(2): 129-136.

A new genus and species of a highly aberrant terrestrial dryopid, Monstrosostea solivaga, is described from southern India. A single male was collected in the Nilgiri Hills at an altitude of 2100 m a.s.l. by sifting forest leaf litter. The new genus is characterised by modified labial and maxillary palpi, antennal configuration and four-segmented tarsi. Franzyops Kodada, 1998 is considered as a junior synonym of Momentum Perkins, 1997.

Mostovski, M.B. & Martínez-Delclós, X. 2000. New Nemestrinoidea (Diptera: Brachycera) from the Upper Jurassic - Lower Cretaceous of Eurasia, taxonomy and palaeobiology. Entomol. Probl. 31(2): 137-148.

New nemestrinoids belonging to the families Rhagionemestriidae and Nemestrinidae from the Jurassic deposits of the Southern Kazakhstan and Germany and Lower Cretaceous deposits of Spain, Russia, and Mongolia are described. The authors argued including the Heterostominae in the Rhagionemestriidae; and the latter is considered as a connecting link between Xylophagidae and Nemestrinidae. The Nemestrinoidea and Nemestrinidae themselves demonstrate high taxonomic diversity since the Middle - Upper Jurassic although members of the families Rhagionemestriidae and Nemestrinidae appeared in the Lower Jurassic for the first time. Both extinct Archinemestriinae and extant Hirmoneurinae are known since the Jurassic, while Nemestrininae came into palaeontological record in the Lower Cretaceous. Fossil nemestrinids, at least those with long proboscis, are postulated to be connected with bennettites or angiosperms as nectar-feeders and possibly pollinators.

Jendek, E. 2000. Eight new species of the genus Agrilus from Asia (Coleoptera: Buprestidae). Entomol. Probl. 31 (2): 149-154.

Eight new species of the genus Agrilus (Coleoptera, Buprestidae) are described: A. champasak sp.nov., A. myopic sp.nov., A. robustipenis sp.nov., A. pseudoostrinus sp.nov., A. gaoligong sp.nov., A. notoclavus sp.nov., A. charismaticus sp.nov., A. horaki sp.nov.

Jäch, M.A. & Díaz, J.A. 2000. New and little known Palearctic species of the genus Hydraena VI (Coleoptera: Hydraenidae). Entomol. Probl. 31(2): 155-162.

Two new species of Hydraena are described: H. hortensis [northwestern Greece], H. larissae [northern Italy]. One new synonymy is proposed: Hydraena rufipennis Boscá Berga, 1932 = H. claryi Jäch, 1994. A lectotype is designated for H. rufipennis. The remarkable morphological variability of H. stussineri Kuwert, 1888 is described and illustrated. Hydraena delia is recorded from France for the first time.

Hlaváč, P. & Lakota, J. 2000. Redescription and lectotype designation of Lomechusa stangei (Coleoptera: Staphylinidae: Aleocharinae). Entomol. Probl. 31(2): 163-164

Lomechusa stangei (Reitter), comb.nov., is redescribed and illustrated; redescription is based on two female syntypes, one of which was designated as lectotype.

Solodovnikov, A. & Schillhammer, H. 2000. Bisnius speculicollis sp.nov., a new nidicolous rove beetle from the Western Caucasus (Coleoptera: Staphylinidae). Entomol. Probl. 31(2): 165-170.

Bisnius speculicollis sp.nov., a nidicolous rove beetle (Coleoptera: Staphylinidae, Staphylininae) from the burrows of the endemic Caucasian rodent Prometheomys schaposchnikovi Satunin, 1901, is described from the Western Caucasus. The new species is compared with the presumably closely related B. reitteri (Eppelsheim, 1889) and data on the bionomics and distribution of both are provided. The habitus, the aedeagus and important morphological details of the new species, as well as the paramere and the female tergite X of B. reitteri are illustrated. A brief outline on the natural history of P. schaposchnikovi is compiled, and the presumably close ecological relationship of B. speculicollis with its mammal host is discussed.

The first instars of Hydroporus palustris (Linnaeus), H. striola (Gyllenhal), and H. incognitus Sharp are described and illustrated. The larvae used in this study were reared ex ovo from adults collected in Belarus. A preliminary key to the known first instars of Hydroporus is provided.

Zettel, H. 2000. Rhagovelia inexpectata sp.nov., a sibling species of R. sumatrensis from Southeast Asia (Heteroptera: Veliidae). Entomol. Probl. 31 (2): 175-178.

The newly described riffle bug Rhagovelia inexpectata sp.nov. is a sibling species of the common Oriental species R. sumatrensis Lundblad, 1933. Rhagovelia inexpectata sp.nov. occurs in Thailand, Laos, and Vietnam, within the distribution area of R. sumatrensis, and partly syntopic with this species. In contrast with all other Southeast Asian species of Rhagovelia, the macropterous morph of R. inexpectata sp.nov. is predominating.

Northern boundary of its geographical distribution crosses area of Slovakia. It belongs to markedly xerothermophilous orthopterous insect species, occurring in dry steppe or woodland steppe biotopes of Slovakia. This article refers to its distribution in Slovakia.

Agrilus agnatus Kerremans is considered as a valid species. All species are keyed and illustrated. Lectotypes of Agrilus auristernum Obenberger, Agrilus agnatus Kerremans, Agrilus bifoveolatus Kerremans are designated.
