We report the occurrence of Cevaeria estebani Tavakilian, 2004 (Cerambycinae, Cerambycini) for the first time in Amazonas, Brazil. This species was previously recorded from French Guiana and Bolivia. We provide a distribution map for C. estebani and photographs of the habitus of the new record and its potential mimetic species, the chrysomelid Sceloenopla maculata (Olivier, 1792).

The monotypic genus Indapiodes Miroshnikov & Tichý, 2018 is reviewed. The genus and the type species are morphologically redescribed in detail. A second species is newly described from Maharashtra Province, India. Indapiodes is transferred from its original placement in the tribe Tillomorphini to the tribe Obriini.

A new species, Margites lobanovi Miroshnikov, sp. n., is described from southern Vietnam. It is very similar to M. prothemicollis Jacquot, 2019 from northern Vietnam, but differs by the significantly longer antennae, the more strongly elongate many antennomeres, the somewhat peculiar structure of the pronotum, in particular, the anterior margin being broadly rounded, the presence of a strongly developed shiny median area in the basal part, the slightly shorter elytra, as well as by the structure of the genitalia, namely, the clearly narrower penis uniformly narrowed towards apex in the apical part, its ventral lobe being clearly greater extending beyond apex of the dorsal lobe, the significantly narrower tegmen, the distinctly narrower and more strongly elongate parameres, its apicies being more strongly sharpened, the clearly wider tergite 8 being shortly truncate apically.

Zoodes fulguratus is a common species of Cerambycidae, reported from Vietnam, Nepal, Laos, Burma, and China. To date, no mitochondrial genomes of the genus Zoodes have been reported. In this study, we sequenced and analyzed the first mitochondrial genome of Z. fulguratus to discuss its phylogenetic relationship within the subfamily Cerambycinae. This mitochondrial genome showed the typical insect gene arrangement: a circular molecule of 15,885 bp long with 13 protein-coding genes, two ribosomal RNA genes (rRNAs), and 22 transfer RNA genes (tRNAs). The AT content of the whole mitogenome was 74.2% with a high asymmetric nucleotide presentation revealed by a positive AT-skew (0.067) and a negative GC-skew (-0.178), whereas the AT content of the A + T rich region was 80%. The Maximum likelihood (ML) and Bayesian inference (BI) phylogenetic analyses showed that Z. fulguratus is a sister clade of Gnatholea eburifera.

The unpublished formal synonymy of Callichroma chiriquina Bates, 1879, C. opiparum Bates, 1874, C. compressipes Casey, 1912, and C. regalis Casey, 1912 is commented. Schwarzerion carinatum Schmidt, 1924 is removed from the synonym of Callichroma holochlorum holochlorum Bates, 1872, and transferred to the synonymy of Callichroma euthalia Bates, 1879. The species group name “euthalium” is corrected. The type-localities of Schwarzerion carinatum are reported as Colombia and West Indies, and the institution where one of the syntypes is deposited is corrected. Callichroma collarti Fuchs, 1959 is revalidated, and Callichroma magnificum Napp & Martins, 2009 is considered its junior synonym. The status of the specimens of the type series of Callichroma collarti is commented. Additionally, the holotype of Callichroma opiparum Bates, 1874, and the lectotype of Callichroma chiriquina Bates, 1879 are illustrated for the first time.

A new species, Phaea sondenegro Botero, Ahumada-C., and Navas, new species, is described from Colombia (Bolivar department), and the lectotype of Phaea flavovittata Bates, 1881 is illustrated for the first time. Additionally, the known geographical distribution of eleven species of Cerambycidae (Cerambycinae and Lamiinae) is expanded in Colombia.

Eight species-group names of longhorned woodboring beetles in the genus Anelaphus are corrected. Four new species of Anelaphus Linsley, 1936 are described: A. steveni Santos-Silva, sp. nov., from Mexico (Chiapas); A. erici Santos-Silva, sp. nov., from Nicaragua (Granada); A. izabalensis Santos-Silva, sp. nov., from Guatemala (Izabal); and A. zacapensis Santos-Silva, sp. nov., from Guatemala (Zacapa). New Mexican state records for Anelaphus undulatus (Bates, 1880) are provided. The female of Anelaphus pilosus Chemsak and Noguera, 2003 is described for the first time, and the species is newly recorded from Guatemala. The inclusion of Anelaphus nitidipennis Chemsak and Linsley, 1968 in this genus is questioned.

The knowledge of the family Cerambycidae (Coleoptera) from Mexico is updated based on the literature where records of species from Mexico have been published. In addition, Callimoxys sanguinicollis (Olivier, 1800), Laticranium mandibulare Lane 1959, Bellamira scalaris (Say, 1826), and Strangalia opleri Linsley & Chemsak, 1976 are recorded as new records for the country.

Distribution and grouping of the new species are discussed and the key to the East Asian species of the genus is updated to accommodate species recorded from mainland China.

Two new species of the genus Dymasius J. Thomson, 1864 are described. Dymasius medvedevisp. n. (southern India) is similar to D. minor Gahan, 1906, but differs in the very well expressed longitudinal stripes of the elytra, coarser sculpture in their apical part, the length ratio of antennomeres 3–6, the less strongly thickened antennomeres 3–5 in the apical part of the male, and in some other features. Dymasius lubosisp. n. (northern Vietnam) resembles D. simplex Gressitt et Rondon, 1970, but differs clearly in the longer antennae, the more strongly elongate several apical antennomeres, the sharper longitudinal carina on antennomere 1 dorsally, the more strongly developed lateral tubercles of the pronotum, the bicolorous elytra, and other characters.

A brief review of the genus Carinolesthes Vitali, Gouverneur et Chemin, 2017, as well as a key to its species are given. A new species of this genus, C. dembickyi sp. n., is described from the Northeastern India. The need to clarify the generic attribution of C. ningshanensis (Chiang, 1981) is justified. Two new species of the genus Diorthus Gahan, 1891, both from Southern India, D. dembickyi sp. n. and D. aurosetosus sp. n., similar to another South Indian species D. sericeus Gardner, 1939, are described. These three species form a peculiar group which illuminates a very strong morphological similarity between the genera Diorthus and Lamellocerambyx Pic, 1923. At the same time, some recently revealed stable differences between these genera are given. A new species, Zatrephus sumatranus sp. n., is described from Sumatra. The previously unknown female of Elydnus barclayi Miroshnikov, 2017 and male of Pachydissus patricius Holzschuh, 1991 are also described, while the latter species is being recorded from Western Malaysia for the first time. Numerous and detailed colour pictures of the species studied, including their type specimens, are provided.

A brief review of the genus Pneumida J. Thomson, 1864, as well as a key to its species are given. The following new combinations and new synonymy are established: Pneumida trifulvofasciata (Hayashi, 1975), comb. n., Derolus argenteofasciatus (Pic, 1951), comb. n. = Derolus glauciapicalis Gressitt et Rondon, 1970, syn. n. Pneumida trifulvofasciata comb. n., described from Borneo, is recorded from Western Malaysia and generally from Indochina for the first time

A new species, Mimimbrius sabahensis Miroshnikov et Heffern, sp. n., is described from Borneo. It is especially similar to M. dembickyi Miroshnikov, 2017 inhabiting Southern Thailand, but differs clearly by the somewhat peculiar sculpture of the pronotal disc, the more strongly developed recumbent light setation in its apical third; the presence of a distinct emargination at the apex of the last (visible) sternite in the male; the noticeably narrower longitudinal strips of recumbent, dense, light setae between the upper lobes of the eyes, especially so in the male; the structure of the male genitalia, in particular, the peculiar shape of the apical parts of tergite 8, penis and tegmen, as well as by some other minor traits

A number of recent studies have demonstrated the potential for using blends of pheromones of cerambycid beetles to attract several species simultaneously. Here, we tested the effects of adding the pheromones of two invasive species, Trichoferus campestris (Faldermann) and Aromia bungii (Faldermann), on the attraction of native species to a generic blend of synthesized pheromones, in season-long field trials at 12 sites in Pennsylvania. Of the four species attracted in significant numbers, Megacyllene caryae (Gahan), Phymatodes amoenus (Say), and P. testaceus (L.) (all subfamily Cerambycinae) were not significantly affected by the addition of the T. campestris pheromone trichoferone and the A. bungii pheromone (E)-2-cis-6,7-epoxynonenal to the generic blend. In contrast, trap catches of Sternidius alpha (Say) (subfamily Lamiinae) were completely shut down by addition of the pheromones of the two exotic species. In addition, there was no indication that any native species were attracted to trichoferone or (E)-2-cis-6,7-epoxynonenal, suggesting that these pheromones are probably not used by species native to eastern North America.

In this work, a new species, Kunbir shennongjiaensis sp. nov., from Shennongjia Forestry District, China, is described and illustrated. The differences between Kunbir shennongjiaensis sp. nov. and related species are provided.

Moreover, the geographical distribution of 45 species of Cerambycidae, belonging to the subfamilies Cerambycinae, Lamiinae and Prioninae, is expanded, including nine new country records for Colombia and a further locality in Colombia for nine species.

Epipedocera atra is a common species of Epipedocera Chevrolat which distributed in South China and some countries in Southeast Asia. The complete mitochondria genome of E. atra was 15,662 bp in length, with 37 genes, including 13 protein-coding genes (PCGs), 22 tRNA genes (tRNAs), and 2 rRNA genes (rRNAs). The nucleotide composition was highly A + T biased, accounting for 70.34% of the whole mitogenome. Phylogenetic analysis indicated that E. atra had a close relationship with Xylotrechus grayii White.

Capezoum Adlbauer, 2003 is known only from male specimens. Herein, we describe two new species: Capezoum richardi sp. nov. and C. brunneopunctatus sp. nov., from the Northern Cape region in South-Africa. The discovery of these new species, one of them represented by both sexes, allowed us to describe the hitherto unknown female. Moreover, the genus is transferred to the tribe Xystrocerini and a key to the species of the genus is provided. Lastly, the position of Mythozoum Thomson, 1878 in Cerambycidae is discussed.

Merostenus exiguous Zayas, 1975 (currently, Caribbomerus exiguus) is transferred to Perigracilia Linsley, 1942. Information on the type series of M. exiguous is provided, and a lectotype is designated to the species. Two new species of Caribbomerus are described from Cuba: C. elieri, and C. zayasi.

Here, we study the pheromone chemistry of two South American cerambycid beetle species, and their behavioral responses to candidate pheromone components. Adult males of Stizocera phtisica Gounelle (subfamily Cerambycinae: tribe Elaphidiini) produced a sex-specific blend of (R)-3-hydroxyhexan-2-one with lesser amounts of 3-methylthiopropan-1-ol. In field bioassays, traps baited with racemic 3-hydroxyhexan-2-one and 3-methylthiopropan-1-ol did not catch conspecific beetles, but did catch both sexes of a sympatric species, Chydarteres dimidiatus dimidiatus (F.) (Cerambycinae: Trachyderini). We found that males of this species also produce (R)-3-hydroxyhexan-2-one and 3-methylthiopropan-1-ol, and small amounts of 2-phenylethanol. Subsequent bioassays with these compounds showed that a blend of 3-hydroxyhexan-2-one and 3-methylthiopropan-1-ol constitutes the aggregation-sex pheromone of C. d. dimidiatus, with 2-phenylethanol not influencing the attraction of conspecifics. During the field bioassays, six other species in the Cerambycinae also were caught in significant numbers, including Aglaoschema ventrale (Germar) (tribe Compsocerini), congeners Chrysoprasis aurigena (Germar), Chrysoprasis linearis Bates, and an unidentified Chrysoprasis species (Dichophyiini), and Cotyclytus curvatus (Germar) and Itaclytus olivaceus (Laporte & Gory) (both Clytini), suggesting that one or more of the compounds tested are also pheromone components for these species.

The Rio Doce State Park (“PERD”) is the largest Atlantic Forest remnant in Minas Gerais State, Brazil, with predominantly semi-deciduous forests. The longhorned beetles of the Cerambycinae subfamily (Coleoptera: Cerambycidae) are distributed worldwide, developing on healthy, stressed or recently dead trees. Faunistic surveys are necessary to understand about the Minas Gerais’ cerambycid fauna due to a lack of research, especially in the eastern region of the state. A list of species of the subfamily Cerambycinae (Coleoptera: Cerambycidae), collected in the PERD during the rainy season (September 2013- February 2014), is presented. The beetles were collected using a light trap and through their emergence from Anadenanthera colubrina (Vell.) Brenan (Fabaceae) logs. A total of 663 individuals of 33 species, 30 genera, and 15 tribes of the Cerambycinae subfamily were collected. The species Malacopterus tenellus (Fabricius, 1801) was registered for the first time in Minas Gerais State, while A. colubrina is a new host plant for 14 Cerambycinae species. The geographical distribution, number of host plants and materials examined are presented for each species collected. This is the first list of Cerambycidae species from the Rio Doce State Park.

Paraclytus xiongi sp. nov. is described from Yunnan, China. Habitus of adults, hind wings, male terminalia and intraspecific variation of Paraclytus xiongi sp. nov. are illustrated. The differences between Paraclytus xiongi sp. nov. and related species are provided.

The late Ubirajara Ribeiro Martins de Souza (1932–2015) described 390 genera in Cerambycidae (including Disteniinae = Disteniidae), alone or with collaborators (especially the first author of this work), and two genera in Languriinae (Erotylidae). Some of them are currently in synonymy, and a few were replaced due to homonymy. Herein we propose new replacement names for two of his Cerambycidae genus-group names. These belong to two different tribes: Elaphidiini (currently with 93 genera) and Eligmodermini (currently with five genera).

Anoplistes kaszabi sp. nov. is described from Mongolia. Distinguishing characters from closely related Anoplistes mongolicus Ganglbauer, 1889 are presented and their ecological dissimilarity is discussed. High-quality stacked photographs of the habitus of the specimens are presented for both species and their geographical distributions are mapped. The new species differs from A. mongolicus mainly by the more elongate pronotum with different sculpture, the more evenly and densely pubescent elytra, the slender body of smaller size in both sexes, as well as by the different shape of female antennomeres. Additionally, they are most likely associated with two different host plants. Moreover, Anoplistes amoenus Reitter, 1898 (stat. res.) is herein restored to specific rank due to its clear distinctness compared to the discussed taxa.

Falsestoloides Breuning, 1954 is synonymized with Parestola Bates, 1880, Falsestoloides mexicana Breuning, 1954 is synonymized with Parestola zapotensis Bates, 1880, and a new state record is provided for the species.

Longhorn beetles are among the most important groups of invasive forest insects worldwide. In parallel, they represent one of the most well-studied insect groups in terms of chemical ecology. Longhorn beetle aggregation-sex pheromones are commonly used as trap lures for specific and generic surveillance programs at points of entry and may play a key role in determining the success or failure of exotic species establishment. An exotic species might be more likely to establish in a novel habitat if it relies on a pheromone channel that is different to that of native species active at the same time of year and day, allowing for unhindered mate location (i.e., pheromone-free space hypothesis). In this study, we first tested the attractiveness of single pheromone components (i.e., racemic 3-hydroxyhexan-2-one, racemic 3-hydroxyoctan-2-one, and syn-2,3-hexanediol), and their binary and tertiary combinations, to native and exotic longhorn beetle species in Canada and Italy. Second, we exploited trap catches to determine their seasonal flight activity. Third, we used pheromone-baited "timer traps" to determine longhorn beetle daily flight activity. The response to single pheromones and their combinations was mostly species specific but the combination of more than one pheromone component allowed catch of multiple species simultaneously in Italy. The response of the exotic species to pheromone components, coupled with results on seasonal and daily flight activity, provided partial support for the pheromone-free space hypothesis. This study aids in the understanding of longhorn beetle chemical ecology and confirms that pheromones can play a key role in longhorn beetle invasions.

Four new species and one new genus are described: Nesanoplium spinosum (Elaphidiini), from Honduras; Psyrassa zacki (Elaphidiini), from Mexico and Guatemala; Euderces ecuadorensis (Tillomorphini), from Ecuador; and Xela tysoni (Methiini), gen. nov., from Guatemala.

Full generic statuses of Plavichydissus Pic, 1946, stat. rest., Laomargites Pic, 1923, stat. rest. and Lamellocerambyx Pic, 1923, stat. rest. are restored. Reviews of these genera, as well as keys to species of the former two are given. Annotated checklists of the Asian species of the genera Pachydissus Newman, 1838 and Margites Gahan, 1891, as well as of all species of Diorthus Gahan, 1891 are presented. The following new species are described and new specific combinations established: Plavichydissus grossepunctatus (Gressitt et Rondon, 1970), comb. n., P. irinae sp. n. (Vietnam), P. aggregatus (Holzschuh, 1999), comb. n., P. sulcicollis (Gahan, 1893), comb. n., P. myanmarensis sp. n. (Myanmar), P. makarovi sp. n. (Thailand), P. nataliae sp. n. (Vietnam), P. decipiens (Holzschuh, 1989), comb. n., P. penangensis sp. n. (Western Malaysia), P. sodalis (Holzschuh, 1999), comb. n., P. dembickyi sp. n.

The synonymization of the genus Diorthus with the genus Tapinolachnus J. Thomson, 1865 is confirmed as being wrong. The following new synonymy is established: Tapinolachnus = Mimoderolus (Aeolesthes subgen.) Pic, 1933, syn. n. (non syn. pro Derolus Gahan, 1891). Dymasius strigosus J. Thomson, 1864, sp. rest. is resurrected from the synonymy with Dymasius macilentus (Pascoe, 1859). The genus Derolydnus Hüdepohl, 1989 is reported from Indochina for the first time. New records of a number of species from other genera are given as well, thus one way or another extending their known distribution areas, sometimes very significantly so. The lectotypes of Margites modicus Gahan, 1906, Diorthus sericeus Gardner, 1939 and Tapinolachnus xyliae (Fisher, 1940), comb. n. are designated. Abundant pictures of the species studied, including numerous type specimens, are provided

Two new species of Neotropical Elaphidiini (Cerambycidae: Cerambycinae) are described and illustrated: Anelaphus flavofasciatus sp. nov. from Colombia and Stizocera wappesi sp. nov. from Bolivia. Additionally, an updated key to South American species of Anelaphus Linsley, 1936 is provided.
