JOURNAL FREE ACCESSA new species, Eximilimosina scutelliseta is described and illustrated from China, Laos and Vietnam. This species is easily distinguishable from the other members of the genus by the presence of microsetae on disc of scutellum.View full abstractDownload PDF (617K) -

JOURNAL FREE ACCESSWe inspected 97 specimens of bat flies of the family Nycteribiidae parasitizing wild bats in Japan. Bat flies representing 8 species of 4 genera (Basilia spp., Nycteribia spp., Penicillidia spp. and Phthiridium sp.) were obtained from bats representing 11 species of 5 genera (Barbastella sp., Miniopterus spp., Myotis spp., Plecotus sp. and Rhinolophus spp.). We also surveyed past reports on bat flies in Japan wherein host bat species and number of insects collected from them are explicitly recorded. On the basis of these data, we identified 3 bat flies primarily associated with a single host bat, and 4 bat flies associated with 2 congenic host bats. Only 1 species, B. truncata endoi, was associated with 4 bat species representing 3 genera, although these bats were placed in a well-defined clade in the bat phylogeny. Hence, the nycteribiid bat flies generally exhibit different levels of specificity to their host bats, which may be species-specific, genus-specific or genus-group-specific. Meanwhile, when the molecular phylogeny of the bat flies was compared with that of the host bats, no co-speciating pattern was observed, suggesting that host shifts must have occurred at a considerable frequency in the evolutionary course of the bat flies.View full abstractDownload PDF (261K)

JOURNAL FREE ACCESSOccurrence of two rare mosquito species, Aedes bekkui and Verrallina nobukonis, was confirmed in southern Osaka Prefecture, Japan during the course of mosquito study in western Japan. A temporal ground pool appeared in rainy season from June to August 2010 was examined by dipping for occurrence of larvae. Biting mosquito collections were made by a sucking tube and/or a hand net beside the ground pool. Sweeping collection was also conducted around the pool. Eight and 4 mosquito species were collected in adult and larval collections, respectively. Both adults and larvae of Ae. bekkui were collected, whereas Ve. nobukonis was collected only in adult collections.View full abstractDownload PDF (427K)

—Suspected cases of erratic migration of Otodectes cynotis and a case of Aleuroglyphus ovatus infestation—Toshinari KATO, Yatsuji ITO, Hiroshi NAKAO, Teruki KADOSAKA2011 Volume 62 Issue 3 Pages 199-204

JOURNAL FREE ACCESSWe reported 5 patients complaining of intermittent tinnitus and 1 patient complaining of continual tinnitus caused by large numbers of tiny mites crawling on the eardrum. In each of the 5 patients complaining of intermittent tinnitus, parasitic mites, Otodectes cynotis, from their pet cat's external ear canal accidentally entered the patient's own external auditory canal. Each of the 4 patients slept together in the same bed with their cat and 1 patient lived in the same room with a cat. Tinnitus occurred due to mite activity on the eardrum. Since mites removed from pets are small, most otolaryngologists overlook or fail to find these mites on standard otoscopy. A 26-year-old Philippine male working in a poultry farm complained of continual tinnitus. We found many parasitic mites crawling on his right eardrum under the impacted cerumen. Those mites were identified as Aleuroglyphus ovatus mites, which breed in assorted types of chicken feed. This is the first case report of A. ovatus infestation in the human external auditory canal. In all 6 cases, the patients underwent repeated washing of the external auditory canal with saline. We were able to record the findings in these cases on video. We emphasize that very careful observation of the eardrum by video and medical interview that includes questions about living with pets and occupation are very helpful to the diagnosis of tinnitus.View full abstractDownload PDF (1154K)
