Four new species of the genus Aphthonoides Jacoby, 1885 are described: A. bukittinggiensis sp. n. (from Indonesia), A. tambunanensis sp. n., A. trusmadiensis sp. n. (from Malaysia) from the beccarii species-group, and A. pseudosabahensis sp. n. (from Malaysia) from the laticollis species-group. The figures of general views, aedeagi and spermathecae are given for them and the majority of related species. A new identification key to species of the genus Aphthonoides from Sundaland and the Philippines is given. Two new species-group (the beccarii and the laticollis) are proposed. The species of the laticollis group have the wide pronotum (more than 1.45 times as wide as long) with lateral margins nearly straight, converging anteriorly; anterior setigerous pore on lateral margin of the pronotum not or very slightly protrude outwards; basal margin of the pronotum strongly convex; male protarsomere I not or very slightly enlarged. Species of the beccarii group have the narrower pronotum (1.35 or less times as wide as long) with lateral margins straight or rounded, not converging anteriorly; anterior setigerous pore on lateral margin of the pronotum distinctly protrude outwards; basal margin of the pronotum slightly convex; male protarsomere I distinctly enlarged. The geographical distribution of A. beccarii Jacoby, 1885 and A. laticollis Heikertinger, 1940 has been clarified. The latter species is recorded for Malaysia for the first time.

Aim of study: A defoliating insect, Calomicrus foveolatus, feeding on the Andalusian endemic fir Abies pinsapo (Pinaceae) is herein reported for the first time. Until now, this chrysomelid beetle was known to feed exclusively on Quercus spp. (Fagaceae). Area of study: The study was carried out in the forests of A. pinsapo, restricted to protected mountainous areas of western Málaga and eastern Cádiz in southern Spain. Material and methods: Since 2001 we carried out monitoring for potentially damaging insects at five sites of the pinsapo forests at least once a year. The monitoring visits were increased to 2-3 times a year at the sites that contained the phytophagous species. Main results: Calomicrus foveolatus was observed feeding on pinsapo needles in sites of Sierra de las Nieves National Park, in Málaga province. Besides, damaged pinsapos were also observed in Sierra de Grazalema Natural Park in Cádiz Province. Feeding activity consisted of partial and superficial damage from gnawing on the upper side of the needles; eventually producing death of the needles and finally death of the entire shoot. The recognition characteristics of the beetle and its injury on the needles and branches are described. Research highlights: It is described, for the first time, the attack of a phytophagous leaf beetle, C. foveolatus, to the endemic conifer A. pinsapo, in the National Park “Sierra de las Nieves” in the province of Málaga, Spain. Further monitoring of this beetle is necessary for the sustainable management of this protected fir endemic to the Baetic regions.

Ten new species of the genus Taumacera Thunberg, 1814 are described from Malaysia, Indonesia, and Thailand: T. alexklimenkoi sp. n. from the viridis species-group; T. lamellicornis sp. n. from the insignis speciesgroup; T. pseudoantennata sp. n. from the antennata species-group; T. pseudonigricornis sp. n. from the nigricornis species-group; T. sinabungensis sp. n. and T. trizonalis sp. n. from the deusta species-group. Taumacera bezdeki sp. n. and T. moseykoi sp. n., having long antennae covered long, erected setae and metatibiae with apical process, as well as T. carinatipennis sp. n. and T. unicoloripennis sp. n., having not modified antenna and metatibiae with apical process, are unassigned to any species-group. The figures of general views and aedeagi are given for them and the majority of related species. The new identification keys for males of the antennata and the nigricornis species-groups, as well as for the Sumatran representatives of the deusta species-group with the angulate pronotum are proposed. A new colour form of T. monstrosa (Jacoby, 1899) with darkened elytra is described from Sumatra. Taumacera javanensis (Jacoby, 1895) has antennomeres VII and VIII dilated with distinct spine directed backwards on the latter and is assigned to the antennata species-group. The lectotype of T. javanensis is designated. The following new synonymy is proposed: Taumacera antennata (Mohamedsaid, 1997) = T. musaamani (Mohamedsaid, 2010), syn. n.

Taxonomic and nomenclatural changes in African Galerucinae are explicated. Rohania leonardii n. sp. is described from Kenya. The new combination Palpoxena nigripennis (Weise 1907) is proposed. Besides, additional information on the distribution of the following other African species is presented: Calomicrus weisei (Jacoby 1897), Exosoma apicale (Weise 1902), E. tibiale (Jacoby 1899), Huillania salisburiensis (Jacoby 1903), Megalognatha suturalis Baly 1878, M. bisulcata Laboissière 1927, and Polexima citernii (Jacoby 1899).

A new Longitarsus species is described from Western Balkans: Longitarsus carolileonardii (Bosnia and Herzegovina: Mojmilo) following the study of five specimens housed at the Hungarian Natural History Museum, Budapest. The new species belongs to the Longitarsus rubellus species group including also L. rubellus (Foudras 1860), L. gruevi Leonardi & Mohr 1974, L. refugiensis Leonardi & Mohr 1974 and L. ibericus Leonardi & Mohr 1974. Altogether, these species have similar habitus, but can be distinguished from each other mainly by the male sexual characters. A comparative table summarizes the diagnostic characters for all the species in the group. New distributional, biological and morphological data are also given.

Monoxia obesula, a species native to the U.S.A. and adventive in western Mediterranean, is recorded in Greece for the first time. In 2022, one female specimen was collected on Théra Island (Santorini Archipelago, Aegean Sea), becoming the easternmost Mediterranean record. Host plants are Amaranthaceae species, particularly Atriplex halimus occurring in saline habitats. The presence of Monoxia obesula in Greece is alarming because it spreads its occurrence towards the eastern Mediterranean and may therefore pose a significant danger for Atriplex halimus stands.

Simple Summary: The distribution of many beetle species remains poorly known, and the knowledge of their ecological requirements is even more fragmentary. Starting with published data on the flea beetle genus Arsipoda in New Caledonia, we investigated the habitat preferences of the 21 species from this area. These species are significantly associated with vegetation growing on volcanic substrates. A few widespread species are also present in secondary vegetation, such as savanna and brushwood. We estimated current suitable areas for the genus using ecological niche models, and identified possible under-sampled areas, mainly in the central sector of the main island. New Caledonia is one of the major biodiversity hotspots. The flea beetle genus Arsipoda (Coleoptera Chrysomelidae) is present with 21 species, all endemic. We investigated, using GIS analyses and ecological niche models, the habitat preferences of these species in terms of vegetation types, altitude, and climate, and assessed the adequacy of knowledge on the spatial parameters affecting the distribution of the genus in New Caledonia. Altitude and geology seem to play an important role in shaping species distribution. Volcanic substrate allows the growth of ultramafic vegetation, which includes most of their host plants. From a biogeographic and conservation perspective, our results report a deep link between Arsipoda species and their habitats, making them particularly sensitive to environmental modifications.

The current climate has facilitated biological invasions worldwide, with the spread of invasive species accelerating over the last few decades. Introductions of species are often accidental and facilitated by many factors, including intercontinental trade. In this paper, we explore the secondary range of an adventive flea beetle native to Asia, Luperomorpha xanthodera, which was recently found in many European countries on several occurrences. This species has detrimental effects mainly on ornamental plants, being destructive to leaves and flowers, which can have serious negative economic consequences. We inferred current and future potential distribution of this alien species using Ecological Niche Modelling (ENM) and analysed the future increase in suitable areas in European countries. Suitable climatic conditions for L. xanthodera are assumed to be similar to that in areas where this species currently occurs, which includes Ireland and some Balkan countries, where the species is not recorded yet. In the future, a North-eastern expansion is predicted, with many countries currently lacking suitable climatic conditions for L. xanthodera becoming suitable and potentially colonizable by this species. The geographic trend revealed and quantified in our analysis follows the increase in the mean temperature in the coldest quarter of the year, which is predicted to rise in the next 30 years. This will result in this species spreading from south-western Europe to North-Eastern countries, such as Poland, Ukraine, Romania, Belarus and Latvia, which should adopt preventive measures to avoid the accidental introduction of L. xanthodera.

Monolepta hieroglyphica (Motschulsky, 1858) is a major pest of potato, maize, cotton and sorghum in China. In this study, we sequenced and analyzed the complete mitochondrial genome (mitogenome) of M. hieroglyphica. This mitogenome was 15,761 bp long and encoded 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs) and two ribosomal RNA unit genes (rRNAs). Gene order was conserved and identical to most other previously sequenced Galerucinae Most PCGs of M. hieroglyphica have the conventional start codons ATN (six ATT, five ATG and one ATC), with the exception of nad1 (TTG). Except for three genes (cox1, nad4 and nad5) end with the incomplete stop codon T––, all other PCGs terminated with the stop codon TAA or TAG. The whole mitogenome exhibited heavy AT nucleotide bias (80.0%). Phylogenetic analysis positioned M. hieroglyphica in a well-supported clade within the subfamily Galerucinae with Monolepta occifluvis, Monolepta sp. and Paleosepharia posticata. These results provided an important basis for further studies on mitochondrial genome and phylogenetics of Galerucinae.

The aim of this study is to deepen the knowledge of five poorly studied Longitarsus species in order to elucidate their taxonomic position within the genus. For each of them further diagnostic characters and many new collecting localities are supplied. One new synonymy and one change of status are proposed: L. callidus Warchalowski 1967 = L. aphthonoides Weise 1887 syn. nov., and L. lateripunctatus personatus Weise 1893 is raised to valid species. The morphologically similar L. curtus (Allard 1860) and L. monticola Kutschera 1863 are also examined, providing new male and female diagnostic characters for their identification, as well as several European and Italian new collecting localities.

New Caledonia is one of the major biodiversity hotspots. The flea beetle genus Arsipoda (Coleoptera Chrysomelidae) is present with 21 species, all endemic. We investigated, using GIS analyses and ecological niche models, the habitat preferences of these species in terms of vegetation types, altitude, and climate, and assessed the adequacy of knowledge on the spatial parameters affecting the distribution of the genus in New Caledonia. Altitude and geology seem to play an important role in shaping species distribution. Volcanic substrate allows the growth of ultramafic vegetation, which includes most of their host plants. From a biogeographic and conservation perspective, our results report a deep link between Arsipoda species and their habitats, making them particularly sensitive to environmental modifications.

A new substitute name, Liroetis medvedevi nom. nov., is proposed for L. nigricollis Medvedev, 2009 preoccupied by L. nigricollis (Jiang, 1990). The following new synonyms are established: Liroetis aeneipennis Weise, 1889 = L. tiemushannis Jiang, 1988, syn. nov.; Liroetis ephippiatus Laboissière, 1930 = Zangia signata Jiang, 1990, syn. nov. = L. postmaculatus Lopatin, 2004, syn. nov.; Liroetis leechi Jacoby, 1890 = L. verticalis Jiang, 1988, syn. nov.; Liroetis nigricollis (Jiang, 1990) = L. unicolor Zhang, Li & Yang, 2008, syn. nov.; Liroetis reitteri (Pic, 1934) = Pseudoliroetis trifasciata Jiang, 1992, syn. nov. The spelling of Liroetis tiemushannis Jiang, 1988 is fixed using the First Reviser Principle. Species of Liroetis are divided into five species-groups based on the combination of the following characters: presence/absence of border on anterior pronotal margin, width/length ratio of pronotum, structure of aedeagus, presence/absence of metatibial spur. The established groups are: the aeneipennis group, the aurantiacus group, the flavipennis group, the fulvipennis group, and the grandis group. The gender of Liroetis is masculine.

In addition, the photographs of adult habitus and male genitalia of M. sumatrana Jacoby are given.

Dispersion–reproduction trade‐offs are important to explore the evolutionary mechanism of dispersal strategies and the adaptive significance of dispersion in insects. In our previous study, variations in hindwing length were found in Japanese populations of the leaf beetle Galerucella grisescens (Joannis) (Coleoptera: Chrysomelidae). They were distinctly divided into either long‐winged (LW) or short‐winged (SW) morphs in the field. The LW morphs were distributed widely in Japan, whereas the SW morphs were found in restricted areas in Honshu, the main island of Japan. We examined the possible existence of trade‐offs between dispersion and reproduction in G. grisescens by laboratory experiments. Larval duration and adult body size (head width) were not significantly different between LW and SW strains, but adult body weight was larger in some LW strains than in SW strains, most likely due to the size of hindwings and legs as well as to the development of flight muscles. Although the pre‐oviposition period was not significantly different among strains, female longevity and fertility were significantly higher in SW than in LW strains. Long‐winged individuals displayed flutter behaviours, suggesting their flight dispersal abilities, but SW individuals did not. Femurs of LW individuals were significantly longer on all legs compared to SW strains and the former walked faster than the latter. The present results indicate the presence of a dispersion–reproduction trade‐off in G. grisescens, in which SW strains have advantages in reproductive abilities and LW strains in dispersal abilities.

The current climate has facilitated biological invasions worldwide, with the spread of invasive species accelerating over the last few decades. Introductions of species are often accidental and facilitated by many factors, including intercontinental trade. In this paper, we explore the secondary range of an adventive fl ea beetle native to Asia, Luperomorpha xanthodera, which was recently found in many European countries on several occurrences. This species has detrimental effects mainly on ornamental plants, being destructive to leaves and fl owers, which can have serious negative economic consequences. We inferred current and future potential distribution of this alien species using Ecological Niche Modelling (ENM) and analysed the future increase in suitable areas in European countries. Suitable climatic conditions for L. xanthodera are assumed to be similar to that in areas where this species currently occurs, which includes Ireland and some Balkan countries, where the species is not recorded yet. In the future, a North-eastern expansion is predicted, with many countries currently lacking suitable climatic conditions for L. xanthodera becoming suitable and potentially colonizable by this species. The geographic trend revealed and quantified in our analysis follows the increase in the mean temperature in the coldest quarter of the year, which is predicted to rise in the next 30 years. This will result in this species spreading from south-western Europe to North-Eastern countries, such as Poland, Ukraine, Romania, Belarus and Latvia, which should adopt preventive measures to avoid the accidental introduction of L. xanthodera.

(Galerucinae: Alticini) with the type species Mesopana viridis sp. n. is the most similar to Mesopa Jacoby, 1903, from which it distinctly differs by the transverse prothorax, short antennae, absence of basal convexity on elytra and simple mesotibiae. Cryptocephalus burgeri sp. n. (Cryptocephalinae) is similar to C. kandyensis Weise, 1903 from Sri Lanka and differs in the colour of underside, elytral black spots not margined with flavous, the pygidium with one black spot, the elytral punctation distinct at apex, pro- and mesotibiae of male very weakly widened to apex, tarsi not widened. Eurypelta splendida sp. n. (Eumolpinae) differs from E. modesta (Fabricius, 1792) from Bengal in having narrow longitudinal convexities on elytra, other colour and form of aedeagus and spermatheca. New distributional data and colour variations for Lema yerburyi Jacoby, 1908 (Criocerinae) and Aulacophora impressa (Fabricius, 1801) (Galerucinae) are given.

New substitute names are proposed for preoccupied taxa which are newly transferred to Taumacera from other genera: Taumacera kimotoi nom. nov. (for Acroxena femoralis Kimoto, 1989, nec Platyxantha femoralis Allard, 1889, synonym of T. fulvicollis (Jacoby, 1881)); Taumacera indicola nom. nov. (for Acroxena indica Jacoby, 1896, nec Taumacera indica (Jacoby, 1889)); Taumacera medvedevi nom. nov. (for Acroxena nigricornis Medvedev, 1992, nec Taumacera nigricornis (Baly, 1864)).

Platyxantha quadraticollis Jacoby, 1896 is confirmed as a synonym of Theopella bodjoensis (Duvivier, 1885). The name Hyphaenia tibialis Medvedev & Romantsov, 2013 is fixed by the act of the first reviewer principle. Based on the structure of antennae, seven species-groups are recognized (the antennata-group, the cervicornis-group, the deusta-group, the insignis-group, the nasuta-group, the nigricornis-group, and the viridis-group). Lectotypes are designated for Platyxantha balyi Jacoby, 1895 and Dorydea indica Jacoby, 1889, which is important since each of their syntype series consists of two different species [ABSTRACT FROM AUTHOR]

Clavicornaltica is a genus of very small flea beetles living in the leaf litter layer of Asian forests, easily sampled with Winkler extraction. The genus is presumably very rich in species, but their taxonomy is hampered by their small size and morphological uniformity. On a 'taxon expedition'-style field course at Kuala Belalong Field Studies Centre in Brunei Darussalam (Borneo), a new species, Clavicornaltica belalongensis n. sp., was discovered and taxonomically treated by the course participants. We also present the first DNA barcodes for the genus. [ABSTRACT FROM AUTHOR]

Monolepta hieroglyphica (Motschulsky, 1858) is a major pest of potato, maize, cotton and sorghum in China. In this study, we sequenced and analyzed the complete mitochondrial genome (mitogenome) of M. hieroglyphica. This mitogenome was 15,761 bp long and encoded 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs) and two ribosomal RNA unit genes (rRNAs). Gene order was conserved and identical to most other previously sequenced Galerucinae Most PCGs of M. hieroglyphica have the conventional start codons ATN (six ATT, five ATG and one ATC), with the exception of nad1 (TTG). Except for three genes (cox1, nad4 and nad5) end with the incomplete stop codon T––, all other PCGs terminated with the stop codon TAA or TAG. The whole mitogenome exhibited heavy AT nucleotide bias (80.0%). Phylogenetic analysis positioned M. hieroglyphica in a well-supported clade within the subfamily Galerucinae with Monolepta occifluvis, Monolepta sp. and Paleosepharia posticata. These results provided an important basis for further studies on mitochondrial genome and phylogenetics of Galerucinae. [ABSTRACT FROM AUTHOR]

One new species, Mimastra levmedvedevi sp. n. from the group of species with crosslike elytral pattern, is described from Vietnam. Mimastra levmedvedevi sp. n. is most similar to M. arcuata from which differs by details of coloration and by the apex of aedeagus with rather narrow, not emarginate tip on the apex. The figures of general view and aedeagus are given for the new and close species

A revision of the genus Angulaphthona Bechyné, 1960 is provided, with a description of Ang ulaphthona con fusa sp. n. from the Democratic Republic of Congo, and A. rossii sp. n. from Sierra Leone. The following synonymies are proposed: Angulaphthona lat ipennis (Pic, 1921) = A. latipennis zambeziensis (Bechyné, 1959) syn. n. and Angulaphthona pelengensis Bechyné, 1960 = A. exalta Bechyné, 1960 syn. n. The precedence of the name pelengensis is discussed. Angulaphthona violaceomicans (Chen, 1936) comb. n. (transferred from Aphthona) from Sri Lanka is established, and some hypotheses to explain the presence of the genus outside Africa are put forward. A key to the seven known species is supplied, with microphotographs of diagnostic characters, including male and female genitalia. [ABSTRACT FROM AUTHOR]

Longitarsus doeberli sp. nov. (Coleoptera: Chrysomelidae: Galerucinae: Alticini), from Socotra Island is described. The new species is apparently similar to Longitarsus lederi Weise, 1889 from Caucasus with which it shares, in addition to compact body, some adaptive convergences, such as wingless condition and trend of reduction of the metatarsomere I. Based on the structure of the median lobe of aedeagus and the peculiar shape of the spermatheca, the new species shows instead the closest relationships with the species of the L. anchusae group, especially L. anchusae (Paykull, 1799) and L. anatolicus Weise, 1900.
