A female of Colon (Tricolon) enomotoi HOSHINA, 2009 collected from Hokkaido is described for the first time. Two new species of the subgenus Myloechus of Colon are described from the Ryukyus, under the names C. (M.) ryukyuense sp. nov. and C. (M.) rubellum sp. nov. A key to Ryukyuan species of the subfamily Coloninae is given. As a result of this study, the number of Japanese species of Coloninae becomes fifteen.

The genus Tossinola is recorded for the first time from Japan, with T. ryukyuensis sp. nov. described here on the basis of specimens from Tokuno-shima Island and Okinawa-jima Island, the Ryukyus. This new species can easily be distinguished from other species of the genus by the following features: mesoscutum with a large reddish spot, mesopleuron with two reddish spots, first metasomal tergite with moderately coarse punctures, heptagonal male subgenital plate and relatively short ovipositor.

The Aenictus wroughtonii species group is established to include seven species (five named and two new species) occurring in the Oriental and Indo-Australian regions: A. artipus WILSON, A. biroi FOREL, A. camposi WHEELER et CHAPMAN, A. sagei FOREL, A. stenocephalus JAITRONG et YAMANE, sp. nov., A. vieti JAITRONG et YAMANE, sp. nov. and A. wroughtonii FOREL. Three species are restricted to western part of the Oriental region, i.e, India and Sri Lanka (A. biroi, A. sagei and A. wroughtonii), and four are mainly distributed in Southeast Asia (A. artipus, A. camposi, A. stenocephalus sp. nov. and A. vieti sp. nov.). A. artipus is new to Vietnam, and A. camposi is new to Sumatra. Among food source of this species group are small ants of the subfamily Formicinae such as Paratrechina, Prenolepis and Plagiolepis.

The immature stages of Spinarge affinis HARA and SHINOHARA, 2006, are described for the first time. Two closely related species of the three-leaved azaleas, Rhododendron wadanum and R. reticulatum, belonging to the section Brachycalyx of the subgenus Tsutsusi are newly recorded as host plants of S. affinis. Two arborescent Rosaceae, Photinia villosa var. villosa and Malus toringo, both belonging to the subtribe Pyrinae, are newly recorded as host plants of S. fulvicornis (MOCSARY, 1909). The adult and larval characters, host plants and life history traits of the two Spinarge species are discussed. Spinarge affinis and S. fulvicornis have much in common in adult and larval morphology, but the larvae of S. affinis are solitary leaf­-feeders on Rhododendron(Ericaceae) whereas those of S. fulvicornis are gregarious leaf-feeders on Aria, Sorbus, Photinia and Malus (Rosaceae).

A new species of scutacarid mites, Archidispus palcuapi, is described from Japan on the basis of the phoretic females found on the cervical membrane between head and prothorax of the carabid beetle, Acupalpus (Palcuapus) inornatus BATES. This new species is readily distinguished from all the known congeners by the following characteristics: cupules ia and ip are close to opisthosomal dorsal setae d and h2, respectively; coxal setae 1 a, 2a, 4a, 4b and 4c are exceedingly modified; coxal setae 4a and 4b are inserted close by apodemes 4 and the posterior margin of coxistemal plates IV, respectively.

Based on the examination of the type material, we propose to treat Arge captiva watanabei WEI, XIAO and ZHANG, 1999, as a full species, Arge watanabei WEI, XIAO and ZHANG, 1999, and Arge tuberculata HARA and SHINOHARA, 2008, as a junior synonym of Arge minitincisita WEI, 2002. We redescribe Arge watanabei and discuss the characters distinguishing it from Arge captiva (SMITH, 1874)

Based on the rearing of larvae found on Mt. Yunshan, Hunan Province, China, Rubus adenophorus ROLFE (Rosaceae) is recorded as a host plant of Onycholyda odaesana SHINOHARA and BYUN, 1993, a leaf-rolling sawfly known to occur in Korea and China. Brief notes are given for the larva and its life history. This is the first record of the host plant and immature stages of 0. odaesana.
