Redescriptions with illustrations and color photographs are presented for the larval, pupal and adult stages of Armigeres (Armigeres) conjungens Edwards, 1914 based on the specimens collected in Ulu Gombak, Selangor, Malaysia. Illustration of the male genitalia is also made based on the holotype of Ar. conjungens preserved in the Natural History Museum, London. This species is a rainforest mosquito and breeds without exception in the inflorescence bracts of a wild ginger, Zingiber spectabile.

A new black-fly species, Simulium (Nevermannia) artum sp. nov., is described based on male, female (dissected out of pupa), pupal and larval specimens collected from Tochigi and Hokkaido, Japan. This new species is assigned to the vernum species-group and appears to be most closely related to S. subcostatum (Takahasi) in that it has a combination of the following characters; katepisternum bare, female genital fork without any projection directed anteriorly on each arm, pupal frons with three long trichomes on each side, cocoon simple, and larval rectal organ with 0-2 secondary lobules on each lobe. However, S. artum is easily distinguished from S. subcostatum and other known related species by the pupal gill with four long slender filaments usually arising together at the same level from the very short common basal stalk.

Two new species of Simulium (Montisimulium), S. (M.) merga sp. nov. and S. (M.) surachaii sp. nov., are described based on specimens collected at high elevation (2,560m above sea level) in Doi Inthanon National Park, Northern Thailand. Simulium (M.) merga sp. nov. (known for female, male, pupa and mature larva) is distinguished from all the known species of the subgenus by the large paired elements of the pupal gill with 14 slender filaments. Simulium (M.) surachaii sp. nov. (only the female adult is known) is easily distinguished from S. (M.) merga by the much smaller claw tooth.

Simulium oblongum sp. nov. is described based on female, male, pupal and larval specimens collected in Thailand. This new species is characterized by the genitalia of both sexes, especially the elongated cercus in the female and the absence of parameral hooks in the male; the pupal gill with a dendroid type of 31-33 slender filaments; the larval antenna subequal in length to the stem of the labral fan. Based on a combination of these distinctive characteristics observed in this new species, a new subgenus, Asiosimulium, is proposed within the genus Simulium s. l.

Simulium (Simulium) bullatum sp. nov. is described based on reared female adult and pupal specimens collected in Northern Thailand. This new species is assigned to the multistriatum species-group of the subgenus Simulium (Simulium), and is easily distinguished from other known species of this species-group by the pupal gill with an extraordinarily large unpigmented organ at its base, as well as the arrangement of the eight gill filaments.

This report describes human dermatitis that is probably caused by the bite of the house-martin flea, Ceratophyllus farreni chaoi, from a nest of barn swallows. This case represents the first described case of human dermatitis caused by the bite of C. farreni chaoi in Japan, and the first distributional record of the flea in the Chugoku District.

Abstract : In order to clarify whether or not Haemaphysalis flava adults found on vegetation in the summer include a new generation, the activities of the field-collected adults in June 2001, July 2003, and October 2003 were observed in plastic cylinders that were placed outdoors. Haemaphysalis flava adults collected in June and July actively climbed the plastic cylinders immediately after they were released (June and July). However, the activities decreased sharply from the summer and were scarcely observed from the autumn to the following spring (May). Haemaphysalis flava adults collected in October actively climbed the plastic cylinders until the following spring after release (October). Since the new generation of H. flava adults is active until the following spring, these results suggest that the field-collected adults in summer do not include a new generation but those collected in autumn do. The new generation of H. flava adults appears to commence the activity in autumn.

Recent infestation of roof rats in urban areas has caused serious problems among old people who need social welfare services. A questionnaire to care workers in Tokyo revealed cases of old people bitten by rats. Our examination of one of these cases showed that it had been caused by a roof rat. Care workers also claimed in the questionnaire that rooms had been fouled with droppings, residents had been bitten by rat mites, and rat noise disturbed their sleep at night.
