Proctolaelaps bickleyi (Bram) (Acari: Melicharidae) is an edaphic predatory mite commonly associates with insects. Although P. bickleyi has been reported from many countries worldwide, it is reported herein for the first time in Japan from laboratory cultures of Chilo suppressalis (Walker) and Cossus insularis (Staudinger) (Lepidoptera: Crambidae, Cossidae). Proctolaelaps bickleyi is redescribed and illustrated from females, males, deutonymphs, protonymphs and larvae. The morphological ontogeny of idiosomal and leg chaetotaxy is discussed and a key to the Japanese species of Proctolaelaps is provided.

<i>Lobosphaera reniformis</i> (Wat.) Kom. et Fott (=<i>Chlorella reniformis</i> Wat.) so far known only from Japan, and Papua Island, was for the first time found in Antarctica (King George Island, South Shetland Islands). In laboratory cultures a complete life cycle was obtained, and most of its stages were followed by the electron microscopy. Reproduction is by morphologically different autospores. In some large vegetative cells two Golgi apparatuses lying side by side were observed.

The Japanese members of the proturan genus Gracilentulus comprise five species: G. aokii Imadaté, G. chichibuensis Nakamura, G. macrotarsus sp. nov., G. microtrichus sp. nov., and G. europaeus Szeptycki. In the present study, the new Gracilentulus species are described while G. europaeus is described based on Japanese specimens. Gracilentulus europaeus belongs to the “gracilis” group, which was recorded in Japan for the first time herein. Supplementary notes are provided on G. aokii and G. chichibuensis. A key to the species that lack sensillum b’ on the foretarsus is also provided.

The Relationship

Abstract Dorids are one of the largest nudibranch groups, encompassing more than 2000 species. One of the crucial problems with tracing the evolution of dorids is the relationship between cryptobranch dorids (gill cavity present) and phanerobranch dorids (gill cavity absent). Integrative morphological and molecular studies of the enigmatic Japanese dorid species of the cryptobranch genus Cadlina, C. japonica and ‘C.’ sagamiensis, which were collected by the Emperor of Japan (Shōwa era), are presented here for the first time. It is shown that while C. japonica does belong to the Cadlina clade, another Japanese species ‘C.’ sagamiensis is not part of the cryptobranch dorids of the family Cadlinidae, but is related to both the phanerobranch dorid family, Hexabranchidae, and to the cryptobranch family Cadlinellidae stat. nov. A new genus, Showajidaia gen. nov., and new family, Showajidaiidae fam. nov., are proposed for ‘C.’ sagamiensis, and four new species of the genus Cadlina are described based on a dorid-wide molecular phylogenetic analysis, which is the first substantial update of the dorid family system since 2010. Integration of phylogenetic data with an ontogenetic model of dorid evolution suggests that cryptobranch organization can be most reliably assessed as the ancestral state for the majority of dorids.

Laboratory cultures of Trichoderma hamatum produce metabolites that are characterized by an isocyanide functionality. Three such metabolites predominate. One is the known compound trichoviridin (I). The other two, described here for the first time, are 3-(3-isocyano-6-oxabicyclo[3,1,0]hex-2-en-5-yl)acrylic acid (II) and a very unstable compound 3-(3-isocyanocyclopent-2-enylidene-)propionic acid (III). Production of these three metabolites by a random sample of wild isolates of the fungus has been examined. At least one of these isocyanides was isolated from all cultures in which the culture broth inhibited the growth of Micrococcus luteus. The relative amounts of the three isocyanides produced by individual isolates were not the same and cultures were found in which I, II, or III was the main product. The isocyanide III was produced by all wild isolates which had antibiotic activity in their culture broth, and it was present in the concentration range 2–40 mg∙L−1.

Locality Information

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.

AbstractThis review of the tribe Xyleborini (Coleoptera: Scolytidae) includes two genera, Xyleborus Eichhoff, with 17 species, and Xylosandrus Reitter, containing 3 species. All species are described and most are illustrated. Keys for the separation of the genera and species are provided. Distributional and biological data are given. New combinations are: Xyleborus obliquus (Leconte) (= Pityophthorus obliquus Leconte); X. lecontei (Hopkins) (= Ambrosiodmus lecontei Hopkins), and X. sayi (Hopkins) (= Anisandrus sayi Hopkins). New synonymies are: Xyleborus obliquus (Leconte) (= Ambrosiodmus linderae Hopkins); X. obesus Leconte (= Anisandrus populi Swaine); X. ferrugineus (Fabricius) (= X. retusicollis Zimmerman and X. soltaui Hopkins); X. xylographus (Say) (= X. inermis Eichhoff and X. planicollis Zimmerman); X. volvulus (Fabricius) (= X. schwarzi Hopkins and X. rileyi Hopkins), and X. howardi Hopkins (= X. fitchi Hopkins). A Japanese species, X. rubricollis Eichhoff, is reported from the United States for the first time. A neotype is designated for X. xylographus (Say).

Species Being

Phytoseiidae (Acari: Mesostigmata) is an important family of predatory mites, with some species being commercialized as biological control agents for the control of phytophagous mites and small insects. In Peru, 65 species of this family have been recorded so far, with Amblyseius being the most diverse genus, with 11 species. The aim of this study is to report for the first time the presence of Amblyseius tamatavensis Blommers, 1974 in Peru. In South America, this species has so far been reported only in Brazil and Venezuela. In Peru, A. tamatavensis was found on orange plants [Citrus sinensis (L.) Osbeck] in the district of Pangoa, department of Júnin. In the laboratory, collected specimens were observed to feed on Phyllocoptruta oleivora (Ashmed, 1879) (Acari: Eriophyidae) and Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae). Studies to verify the potential of this species as a biological control agent for pests occurring in Peru should be conducted. A key to the Amblyseius species recorded in Peru is presented.

This report presents a revision of the Japanese species of the genus Setodes Rambur (Leptoceridae), and confirms 8 species. Among these are 3 new species: Setodes chirotheca sp. nov., distributed from Hokkaido to eastern Honshu; S. moritai sp. nov., distributed from central to western Honshu and Shikoku; and S. pseudofurcatulus sp. nov., from western Honshu. Additionally, several species are re-described: S. hinumaensis Katsuma 2009, S. ujiensis (Akagi 1960), S. minutus Tsuda 1942b, S. shirasensis Kobayashi 1984, and S. argentatus Matsumura 1907. One species, S. curviseta Kobayashi 1959 was originally described from Kyushu and is now synonymized with S. minutus. The larva, pupa, and case of S. hinumaensis are described for the first time.
