Two new unique hibiscus-inhabiting species of the plant bug genus Sejanus Distant from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Phylinae).

Two new species of the leucophoropterine plant bug genus Sejanus Distant are described, namely S. epicurus n. sp. (Pingtung, Taiwan) and S. ryujin n. sp. (Nagasaki, Japan). Both species were recently confirmed to be associated cryptically with the bracts and flower buds of Hibiscus spp. (Malvaceae). An updated key is provided to aid in identification of the Japanese and Taiwanese congeners.

Reclassification of the plant bug genus Pilophorus in Japan and key to the genera and species of Japanese Pilophorini (Hemiptera: Heteroptera: Miridae: Phylinae).

The Japanese fauna of the myrmecomorphic plant bug genus Pilophorus Hahn is updated and reclassified. Seventeen species are now recognized, including three herein described as new, P. hyotan, P. satoyamanus and P. setulosellus; and P. pullulus Poppius, 1914 which is reinstated as valid and recorded from Japan for the first time. The identity of P. okamotoi Miyamoto Lee, 1966, originally described from Korean Jeju Island and previously confused with P. satoyamanus n. sp., is reconfirmed and rediagnosed. Frequently misidentified species, P. erraticus Linnavuori, 1962 P. pseudoperplexus Josifov, 1987 and P. setulosus Horváth, 1905 as well as the little known taxon, P. choii, are rediagnosed. The distribution and diagnostic features of P. typicus (Distant, 1909) are presented in light of the recognition of P. hyotan n. sp. An updated checklist and a key to genera and species of the tribe Pilophorini are provided to aid in unequivocal identification of every Japanese pilophorine taxon. A new species of Pherolepis Kulik from Kyushu, P. hizenicus, is also described.

First record of Biromiris from the Oriental region, with a new species from Philippines (Hemiptera, Heteroptera, Miridae, Phylinae).

The unique genus Biromiris Schuh is recognized from the Oriental region for the first time, with the description of a new species, Biromiris tomokuniisp. n., from the Philippines.

Further records on the plant bug tribe Hallodapini (Hemiptera: Heteroptera: Miridae: Phylinae) in Asia, with proposition of two new species and a new synonymy.

A total of twelve species in five genera belonging to the phyline plant bug tribe Hallodapini are treated. Two new species are described from Indochina: Cleotomiris inthanon Duwal & Yasunaga sp. nov. (Thailand) and Cleotomiroides vietnamensis Duwal & Yasunaga sp. nov. (Vietnam). New distributional records are also presented for some known species of Hallodapus Fieber and Wygomiris Schuh. Hallodapus persimilis (Poppius) is proposed as a junior synonym of H. ravenar (Poppius). Illustrations of the endosoma for four species, including the new species, are presented. Digital images of the male genitalic structures are shown for nine species, including the two new species, and also female genitalic structures of the species of Cleotomiris Schuh, Cleotomiroides Schuh and Wygomiris Schuh, are provided. The immature forms are documented for the first time for Acrorrhinium inexpectatum (Josifov) and Wygomiris kaliyahae Yasunaga.

A new species of Decomia Poppius from Laos and Thailand, with an annotated checklist and keys to genera and species of tribe Decomiini from Indochina (Hemiptera: Heteroptera: Miridae: Phylinae).

The Indochinese phyline plant bugs, belonging to the recently established tribe Decomiini Schuh & Menard, are reviewed. Fourteen species in four genera, Decomia Poppius, Decomioides Schuh, Malaysiamiris Schuh and Rubrocuneocoris Schuh, are now recognized from Indochina, including a remarkable new species, Decomia ishikawai Yasunaga, Duwal & Lee n. sp., herein diagnosed, described and discussed. The male of Decomia nigrissima Yasunaga, described only on the holotype female, is for the first time reported. An annotated checklist and a key to genera and species are provided to facilitate identification of the Indochinese taxa of the Decomiini.

A unique new genus and species of the phyline plant bug tribe Hallodapini from the Philippines and Thailand (Hemiptera: Heteroptera: Miridae: Phylinae: Hallodapini).

A unique phyline plant bug representing a new genus and a new species, Peniculimiris meniscus, is documented on the basis of a pair of specimens collected from Nakhon Ratchasima, central Thailand and Palawan, the Philippines. The new genus Peniculimiris, herein placed in the tribe Hallodapini, is characteristic in having a bundle of brush-like, stiff setae on the scutellum and presence of a ventral spine on the genital segment of each sex. The phylogenetic position of Peniculimiris in the Hallodapini and the function of the spines are discussed.

Three new species of the ant-mimetic plant bug genus Pilophorus from Japan (Hemiptera: Heteroptera: Miridae: Phylinae: Pilophorini).

Three new species of the ant-mimetic plant bug genus Pilophorus Hahn, P. maeharai, P. nakatanii and P. tagoi, are described from Japan, with information on their host associations. The genus is briefly diagnosed and discussed, including P. typicus (Distant) which is assumed to have two genotypes based on mitochondrial sequence data. The generic placement of P. tagoi, at first sight reminiscent of a certain member of Pherolepis Kulik, is also proven definitely. A checklist of all currently known species of Pilophorus in Japan is provided, with compiled distribution and host records.

Annotated catalogue of the Phylinae (Heteroptera: Miridae) from the Korean Peninsula.

The subfamily Phylinae (Miridae) of the Korean Peninsula are catalogued. A total of 88 species are recorded from the Korean Peninsula.
