Article
A new species of Synoemis Pascoe, 1863 (Silvaninae) is described and illustrated based on one female specimen from Boa Vista, Roraima state, Brazil. Synoemis jandersoni sp. nov. is quite distinctive and can be distinguished from the other species by the lateral margins of the pronotum bearing a deep, V-shaped emargination near each anterior angle,...

Desjardin’s flat bark beetle – Cryptamorpha desjardinsii (Guérin-Méneville, 1844) – is a widespread invasive species that can become a stored products pest and threaten native species. Our objectives were to provide the first detailed records of this species to South America and New Caledonia, and model suitable areas of C. desjardinsii globally ba...

Larval insects use many methods for locomotion. Here we describe a previously unknown jumping behavior in a group of beetle larvae (Coleoptera: Laemophloeidae). We analyze and describe this behavior in Laemophloeus biguttatus and provide information on similar observations for another laemophloeid species, Placonotus testaceus . Laemophloeus bigutt...

The genus Platycotylus Olliff, 1883 (Coleoptera: Tenebrionidae) is recorded from Japan (Nakanoshima Island, Tokara Islands) for the first time, through the discovery of a new and remarkable species, Platycotylus merkli sp. nov. , which is described herein. The male of this new species can be distinguished from all known males of other congeneric sp...

日本の空港・港湾で輸入品に混入していたホソヒラタムシ科甲虫を調査した結果,94 個体の標本から11 属17 種を確認し,各種の識別法を検討した.このうち,10 種はこれまで日本から記録がなく,Telephanus 属と,Monanus 属のMonanops 亜属は属・亜属単位で記録がなかった.また,確認された種のうち9 種はこれまで物資の移動による導入が確認されておらず,Monanops 亜属は亜属単位で初めての導入の確認となった.さらに,本研究を遂行するうえで,日本産本科の分類学的問題点が判明し,以下の変更を加えた:平野(2009, 2010)で分布疑義としながら,日本産種に含められていたMonanus antennatus Grouvelle の日本からの分布の削除;ミナミホソヒラタムシ...

Australonotha gen. nov. (type species: A. monteithi sp. nov.) is described for two specimens collected from Mount Bellender Ker, Queensland, Australia. Apart from having a monocondylic meso-metaventrital articulation, Australonotha shows similarities with other erotylid subfamilies including Dacninae, Cryptophilinae and some smaller bodied glabrous...
Article

The larvae of three species of Toramus Grouvelle and one species of Loberoschema Reitter are described, and morphological character states of larval Toramini Sen Gupta and within Toramus are discussed. Larvae of Toramus attach their exuviae to the distal portions of their abdomen, with each exuvia from the preceding instar attached to one another t...

The genus Airaphilus Redtenbacher, 1858 (Coleoptera: Silvanidae: Silvaninae) is recorded from Japan for the fi rst time. The record is based on the discovery of a new apterous species, Airaphilus abei sp. nov., described and illustrated herein. The new species is similar to Airaphilus fi liformis (Rosenhauer, 1856), however it can be distinguished...

2018) This study revises the taxonomy of Taiwanese species in the genus Psammoecus Latreille, 1829. A new species, P. taiwanensis sp. nov., is described, and six species from Taiwan are recoded for the first time: P. harmandi, Grouvelle, 1912, P. dentatus Grouvelle, 1883, P. trimaculatus Motschulsky, 1858, P. triguttatus Reitter, 1874, P. labyrinth...

A new silvanid genus Dentirotacorimus gen. nov. is described based on specimens collected from Ulu Gombak (Malay Peninsula), Malaysia. Two new species, D. reticulatus sp. nov. and D. zigzag sp. nov., are described herein. A key to species of this genus and a table listing states of diagnostic characters of Corimus-like genera, including this new ge...

Two new species of flea beetles, Clavicornaltica mizusawai n. sp. from Taiwan and C. sakishimana n. sp. from Ishigaki-jima Is., Japan and Taiwan are described. Clavicornaltica takimotoi LeSage, 1997 is additionally described. The genus Clavicornaltica Scherer, 1974 is recorded for the first time from Japan.
Article
The species of the tribe Brontini from Japan and Taiwan are revised. Two new species, Megahyliota cryptolucidus sp. nov. and Macrohyliota sculptus sp. nov. (misidentified with Mac. gracilicornis (Arrow)), are described. Also described are mature larvae of four species, Dendrophagus longicornis Reitter, Mac. sculptus sp. nov., Meg. cryptolucidus sp....
Article
The last instar larva and the pupa of Psammoecus scitus Yoshida & Hirowatari, all instar larvae of P. simoni Grouvelle, and the last instar larva of P. hiranoi Yoshida & Hirowatari are described, and their morphologies are compared among species and instars. Larval association for P. simoni was confirmed by DNA barcoding. Apart from a brief descrip...

Cryptamorpha sculptifrons Reitter, 1889 is redescribed and a lectotype and paralectotype are designated. The mature larva of C. sculptifrons is described. It is hypothesized that a variety described by Grouvelle (1908), C. sculptifrons var. punctifrons from India, might not be conspecific with Japanese C. sculptifrons. It is also suggested that lar...
