The article provides information about the genus Zaplatycerus Timberlake, 1925, a key to the females of its 16 species of the world fauna, and their synopsis with data on the distribution and hosts. Neoplatycerus tshernyshevi Trjapitzin, 2011 from Australia is transferred to Zaplatycerus as Z. tshernyshevi (Trjapitzin, 2011), comb. n.Neoplatycerus tshernyshevi Trjapitzin, 2013 is synonymized under Z. tshernyshevi (Trjapitzin, 2011), syn. n.     

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.     

New data on the taxonomy of ground-beetles (Coleoptera,Carabidae) from Palaearctic Asia

Synonymy of two genus-group names is substantiated: Tricholicinus Poppius, 1912 (type species: Tricholicinus setosus J.R. Sahlberg, 1880) = Martyr Semenov et Znojko, 1929 (type species: Martyr praeteritorum Semenov et Znojko, 1929), syn. n. and Psammodromius Peyerimhoff, 1927 (type species: Psammodromius noctivagus Peyerimhoff, 1927) = Xanthomelina Iablokoff-Khnzorian, 1964 (type species: Apristus zajtzewi Eichler, 1924), syn. n. Synonymy of the following names of the species-group taxa is established: Calosoma (Callisthenes) elegans (Kirsch, 1859) = C. (Callisthenes) declive (Dohrn, 1884), syn. n., lectotype of the latter is designated; Carabus (Semnocarabus) erosus erosus Motschulsky, 1866 = C. (Semnocarabus) erosus karascharensis (Eidam, 1931), syn. n., lectotype of the latter is designated; C. (Semnocarabus) cicatricosulus pseudoerosus Mandl, 1955 = C. (Semnocarabus) bogdanowi semnocosulus Deuve et Tian, 2013, syn. n.; Chlaenius (Dinodes) viridis (Ménétriés, 1832) = Ch. pallidicornis Ballion, 1871, syn. n.; Licinus (Tricholicinus) setosus (J.R. Sahlberg, 1880) = Licinus mongolicus Reitter, 1900, syn. n. = Martyr praeteritorum Semenov et Znojko, 1929, syn. n. = Martyr alter Semenov et Znojko, 1929, syn. n.; Psammodromius zajtzewi (Eichler, 1924), comb. n. (transferred from the genus Xanthomelina Iablokoff-Khnzorian, 1964) = Psammodromius pallidicolor (Mandl, 1973), syn. n. = Psammodromius damanabii Morvan, 1977, syn. n.Calosoma (Callisthenes) rostislavi Semenov, 1906, stat. resurr. is resurrected from synonyms of C. (Callisthenes) declive (Dohrn, 1884).     

Little-Known Weevil Taxa (Coleoptera,Curculionidae) Described by V. I. Motschulsky from the Caucasus

Lectotypes of Orthochaetes caucasicus Motschulsky, 1845 and Opitomorphus brevirostris Motschulsky, 1845 are designated. A new combination and new synonymies are established: Anchonidium caucasicum (Motschulsky, 1845), comb. n.

New data on the fauna and systematics of Palaearctic species of the click-beetle subfamily Agrypninae Candèze, 1857 (Coleoptera,Elateridae)

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.

Several Northern Indian species of Agrypnus Esch. are transferred to Compsolacon Rtt., and their systematic positions are briefly discussed: C. agrestis, C. inlustris (Vats et Kash.), C. jacksoni (Vats et Kash.), C. kuluensis (Vats et Kash.), C. maisus (Vats et Kash.), C. planocorpus (Vats et Kash.), C. rameshi (Vats et Kash.), C. repercussus (Vats et Kash.), C. solanensis (Vats et Kash.), C. souslapisus (Vats et Kash.), C. subargillus (Vats et Kash.), C. subfaenum (Vats et Kash.) and C. sublapideus (Vats et Kash.) (all comb. n.). The following new combinations are also established: Compsolacon aequalis (Cand.) comb. n. and Compsolacon brachychaetus (Kollar) comb. n. (both ex Lacon). The following new synonymies are established: Lacon funebris (Sols.) = Adelocera grisea Schw., syn. n.; = Adelocera incompta Kr., syn. n.; Eumoeus murrayi Cand. = Tetralobus quadrifoveatus Vats et Kash., syn. n.     

New Data on the Taxonomy of the Weevil Subgenus <Emphasis Type="Italic">Caucasoplinthus</Emphasis>, Genus <Emphasis Type="Italic">Plinthus</Emphasis> (Coleoptera,Curculionidae)

The taxonomic composition of the subgenus Caucasoplinthus Davidian, 1995 is revised. The immunis and granulosus groups are downgraded to subgroups of the silphoides and fallax groups, respectively; the voriseki subgroup is transferred from the fallax to the fausti group. Plinthus attilai Davidian et Savitsky, sp. n. and P. ljudae Davidian et Savitsky, sp. n. are described from Turkey and Abkhazia, respectively. New data on the taxonomy, distribution, and ecology of some little-known species are presented. The following new synonymy is established: Molytes vittatus Motschulsky, 1839 (= Meleus irroratus Reitter, 1884, syn. n., = Meleus faldermanni Faust, 1884, syn. n., = Meleus difficilis Faust, 1884, syn. n.).     

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.     

A Review of the Fauna of the Planthopper Family Lophopidae (Homoptera,Fulgoroidea) from Vietnam with Descriptions of New Genera and Species and with Taxonomic Notes

Six new species are described from Vietnam, Apia simplexsp. n., Bisma angulatasp. n., Pitambara trypetoidessp. n., Sarmatoca cathemerinagen. et sp. n., Maracota soulieraegen. et sp. n., and Serida castaneasp. n., and Zeleja thoracalissp. n. from Malaysia. Two new genera, Maracotagen. n. (type species M. soulierae sp. n.) and Sarmatocagen. n. (type species S. cathemerina sp. n.), and a new subgenus Zelomachasubgen. n. (type species Zeleja thoracalis sp. n.) in the genus Zeleja are erected. The genus Binaluana Soulier-Perkins et Stroiński is downgraded to a subgenus of Zeleja Melichar. The genus Silvispina Wang et Soulier-Perkins with an uncertain systematic position is attributed to the subfamily Lophopinae and the tribe Lophopini. The placement of the genus Elasmoscelis Spinola (and, correspondingly, the tribe Elasmoscelini) in the subfamily Menoscinae, the genus Epiptyxis Gerstaecker in the tribe Menoscini, and the genus Jivatma Melichar in the tribe Lophopini is substantiated. New records of 11 species are given from Vietnam, some being first records for this country.

A new species, Silvestrichilis polinaesp. n., differs from all the congeners in the strongly dilated fore femur of the male and female, in the maxillary palpus chaetotaxy, and in the structure of the sensory field on the fore femur of the male.
