The Position of the Palaeozoic Genus <Emphasis Type="Italic">Tunguskagyrus</Emphasis> Yan,Beutel et Lawrence in the Family Triaplidae sensu n. (Coleoptera,Archostemata: Schizophoroidea)

Re-examination of the late Permian Tunguskagyrus planus Yan, Beutel et Lawrence, 2018 has shown that it does not belong to the family Gyrinidae (Adephaga) but should be placed in the family Triaplidae sensu n. (Archostemata) as a congener to “Triaplus” sibiricus Volkov, 2013 (Tunguskagyrus sibiricus (Volkov, 2013), comb. n.). Both these Palaeozoic species, in contrast to the Triassic members of Triaplus Ponomarenko, 1977, have no large metacoxal femoral plates and, therefore, would be better placed apart from the Mesozoic representatives of Triaplus (in a different genus). The synonymy of the family names Triaplidae Ponomarenko, 1977 (= Catiniidae Ponomarenko, 1968, syn. n., nom. praeocc., non Catiniidae Bocquet et Stock, 1957 (Crustacaea, Copepoda), = Coleocatiniidae Ponomarenko et Prokin, 2015, syn. n.) is established. Thus, the family now comprises Avocatinus Ponomarenko, 1969, Catinius Ponomarenko, 1968, Catinoides Ponomarenko, 1969, Macrocatinius Ponomarenko, 1969, Triaplus Ponomarenko, 1977, Triassocatinius Ponomarenko, 1969 and Tunguskagyrus Yan, Beutel et Lawrence, 2018.

New data on the distribution and taxonomy of some Palaearctic species of click-beetles of the subfamily Agrypninae are given. The external morphology and genitalia of the previously unknown females of Compsolacon korotjaevi Gur. and C. agrestis (Vats et Kash.) comb. n. are described.

Revision of the carabid genus <Emphasis Type="Italic">Meroctenus</Emphasis> Gemminger et Harold,with a new status of <Emphasis Type="Italic">Xenodochus</Emphasis> Andrewes (Coleoptera,Carabidae: Harpalini)

Originally described as a monotypical genus with unclear taxonomic position from Sudan, Meroctenus Gemminger et Harold, 1868 is treated as a polytypical genus of the Selenophori genus group with two subgenera: Meroctenus s. str. and Xenodochus Andrewes, 1941, stat. n. (the latter was previously considered a distinct genus). Within Meroctenus, two species are recognized: M. (Meroctenus) crenulatus Chaudoir, 1843 (type species) and M. (M.) mediocris (Andrewes, 1936), comb, n., transferred to Meroctenus s. str. from Xenodochus. A new subspecies M. (M.) crenulatus orientalis subsp. n. is described from Pakistan. Diagnoses of the genus Meroctenus in new interpretation as well as of its two subgenera are discussed, and a taxonomic review of the subgenus Meroctenus s. str. with a key to the species and subspecies is provided. The following synonymy is proposed: Meroctenus Gemminger et Harold, 1868 = Paregaploa Müller, 1947, syn. n.; Meroctenus crenulatus (Chaudoir, 1843) = Egaploa (Paregaploa) conviva Müller, 1947, syn. n. Lectotypes are designated for Ctenomerus crenulatus Chaudoir, 1843 and Xenodus mediocris Andrewes, 1936.     

Two New Species of the Weevil Genus <Emphasis Type="Italic">Mecysmoderes</Emphasis> Schoenherr, 1837 (Coleoptera,Curculionidae: Ceutorhynchinae) from Vietnam

Two new species of the weevil genus Mecysmoderes Schoenherr, 1837 are described from Vietnam. Mecysmoderes (Enzoellus) vladimirisp. n. differs from the type species of Enzoellus and its allies from Thailand and Laos in the larger size, deeper meshes on the pronotum, broader legs and a velvety black sutural spot on the elytra. Mecysmoderes (Xenysmoderes) sergiisp. n. in the shape, coloration, and vestiture of the body is similar to M. consularis Pascoe, but clearly differs in the larger size, strongly and unevenly convex pronotal disc, swollen in the middle part elytra, and a dark scutellar spot.     

Contribution to Systematics of the Genus <Emphasis Type="Italic">Astiphromma</Emphasis> Förster (Hymenoptera,Ichneumonidae: Mesochorinae) from Russia and Adjacent Countries

Material of the genus Astiphromma Förster (Hymenoptera, Ichneumonidae: Mesochorinae) from Russia and adjacent countries in the Zoological Institute, St. Petersburg has been examined. 25 species were identified, 14 of which are new records to the Russian fauna, and 10 are new to the Eastern Palaearctic Region. Four species are new to science: Astiphromma (Astiphromma) flavofaciessp. n., A. (A.) minimumsp. n., A. (A.) paradorsalesp. n., and A. (A.) styleatorsp. n. A new synonymy is established: Astiphromma (Astiphromma) albitarse (Brischke, 1880) = A. punctatum Uchida, 1933, syn. n. For Astiphromma japonense Lee, 1992 a hitherto unknown female is described.
