The life cycle, bionomics and mature larval structures of the Japanese prionocerid species, Idgia iriomoteana Nakane, 1980 were investigated in captivity. The results showed that I. iriomoteana has the following characteristics: (1) the larval morph is less advanced in terms of miniaturization, and larvae pass seven larval molts before they pupate; (2) the life cycle is univoltine with summer, not winter, dormancy; (3) the first instar larvae are larger than the size of the egg, but foetomorphic larval instar (which is observed in the Melyridae: Malachiinae) is not shown. Based on comparison with melyrid species, the degree of miniaturization, dormancy behaviour, adaptation to the tropical and subtropical climates and the adaptive significance of a large first instar larva are all discussed. This study is the first to report the complete life cycle of a member of the family Prionoceridae.

Japanese Anthocorini are reviewed. A total of five genera and 13 species were identified, including two new species described below: Temnostethus mirificus sp. nov. and Anthocoris venustus sp. nov. Previous records of Anthocoris miyamotoi Hiura, 1959 from Japan are considered to be confused with A. venustus sp. nov. Anthocoris nemoralis (Fabricius, 1794), which is a common and widespread species in Europe, is recorded in Japan for the first time; it is assumed to have been accidentally introduced into Japan recently. Temnostethus distans Kerzhner, 1973 and Anthocoris kalopanacis Kerzhner, 1977 are newly recorded in Japan proper. Male and female genitalia are illustrated and described for most of the treated species. Identification keys to the genera and species that occur in Japan are provided. Bionomics are provided for each species. Detailed locality information and distribution maps in Japan are presented for all Japanese species and their zoogeography is discussed.

We describe and illustrate a new eyeless weevil, Yagder serratus gen. & sp. nov., based on a single adult female collected by sifting forest leaf litter in Mexico. A phylogenetic analysis of 39 terminals and 2679 aligned positions from three DNA fragments places the new species into the subfamily Brachycerinae (as incertae sedis) and outside the highly diversified clade of ‘higher’ true weevils. Neither Brachycerinae, nor its tribe Raymondionymini traditionally uniting most eyeless weevils, are monophyletic unless the latter is limited to a Mediterranean core group. Both these taxa are taxonomic dumping-grounds likely containing species-poor sisters of species-rich clades. When resolved, the subfamily Brachycerinae will be likely split into two or more species-poor deeply-divergent subfamilies.

Lectotypes are designated for I. dohrnii and I. macerrima. A new species, I. castroae sp. nov., from Mindanao Island in the Philippines is described and photographed. The new species can be distinguished from its congeners primarily by the unicolored fore tarsus and several male genital characters. A revised key to species of Ischnobaena is provided.

Hypoxys Amyot & Serville, 1843 (Hemiptera: Heteroptera: Pentatomidae: Edessinae), for a long time considered a synonym or subgenus of Edessa Fabricius, 1803, was recently revised and reinstated to the generic rank. This genus comprises 17 described species divided in four species groups: H. quadridens, H. oxyacanthus, H. triangularis, and H. balteatus species group. Also, there is a large number of new species yet to be described. The H. balteatus species group is diagnosed by: pronotum with posterior stripe smoky brown to black with black punctures within, sometimes these punctures are surrounded by small dark spots; punctures of the pronotal disc smaller and paler than those of the posterior stripe; anterolateral margin of pronotum yellow; anterior half of scutellum with punctures large, sparse, and also on dark spots; connexivum uniformly green, without dark spots; thorax ventrally with two pairs of brown to black rounded spots; apex of pseudosutures with black to brown round spots. This species group included so far only H. balteatus (Walker, 1868). Here we describe and assign 15 new species to this group: H. amyoti sp. nov. (Suriname: Powakka; French Guiana), H. aspilogaster sp. nov. (Brazil: Minas Gerais, Espírito Santo and Rio de Janeiro), H. belenensis sp. nov. (Brazil: Pará), H. bergrothi sp. nov. (Venezuela: Amazonas; French Guiana: Saint-Elie), H. breddini sp. nov. (Bolivia: Santa Cruz and San Carlos), H. caquetensis sp. nov. (Colombia: Caquetá), H. favachae sp. nov.

(Suriname: Coronie, Sipaliwini; French Guiana: Cayenne), and H. venustus sp. nov. (Bolivia: Cochabamba). Descriptions, measurements, photos of dorsal and ventral view of each species, and of external genitalia of both sexes, an identification key, and distributional maps are presented.

The knowledge of Anthomyzidae (Diptera: Acalyptratae) in the East Palaearctic area is extended by new taxonomic, biological and distributional information. Two new species of the genus Anthomyza Fallén, 1810, viz. A. aspina sp. nov. (Russia: Far East) and A. breviclavus sp. nov. (North Korea), and a species tentatively affi liated with the genus Zealantha Roháček, 2007, viz. Z. fasciolata sp. nov. (Japan) are described. Although all are based only on females, they are distinctive species unmistakably recognized by external characters and structures of the female postabdomen. Relationships of all new species are discussed. Records of 24 species are presented; 3 species are recorded from the E. Palaearctic, 1 species from continental Asia, 3 species from North Korea and a number of species from particular parts of E. Palaearctic Russia for the fi rst time. An updated checklist of East Palaearctic Anthomyzidae is presented, now comprising 13 genera and 44 species. Taxonomic notes for Anthomyza clara Roháček, 2006, Fungomyza cercata Roháček, 2009 and some other species, and new biological information for Anthomyza trifurca Sueyoshi & Roháček, 2003 are given. Longitudinal dark patterning of the wing found in A. breviclavus sp. nov., represents the fi fth lineage of Anthomyzidae in which this type of pattern has evolved independently. Species richness of Anthomyzidae in the E. Palaearctic is discussed with an estimate of about 60 species occurring in the area.

A number of non-marine coastal invertebrate species have been found to constitute (semi-) cryptic species complexes in recent years. Here it is revealed that rather than a single widespread species, distributed from the Namibian border to the Cape south coast, South African coastal rock pool Ochthebius Leach, 1815 previously referred to Ochthebius capicola (Péringuey, 1892) comprise two distinct taxa. Ochthebius capicola (s. str.) is apparently restricted to the Benguela Ecoregion on the west coast, being replaced by Ochthebius mlamboi sp. nov., in south and east coast localities influenced by the Agulhas Current, including areas of the Eastern Cape province well outside the previous known range of these beetles. The distribution and ecology of the two species is discussed, with reference to biogeographic breaks in southern African coastal taxa, and the emerging view that many ‘widespread’ coastal rock pool Ochthebius may actually be (semi-) cryptic species complexes.

The New Zealand species of the water scavenger beetle genus Berosus Leach, 1817 are reviewed based on freshly collected material and museum specimens. Four species are recognized: Berosus pallidipennis (Sharp, 1884) widespread in the North and South Islands, B. muellerorum sp. nov. from the eastern part of the North Island, and B. halasi sp. nov. and B. maru sp. nov., both endemic to central part of South Island. The synonymy of B. mergus Broun, 1886 with B. pallidipennis is confirmed and lectotypes for both taxa are designated. The larval morphology of B. pallidipennis and B. muellerorum is briefly discussed. Distributional data of all species are reported and illustrated, indicating a noticeable lack of Berosus species in the northern part of North Island and in Stewart Island and the presence of two rare species in the South Island, east of Southern Alps. An identification key to New Zealand species of the genus is provided
