Calcarmyobia from the Oriental and Australasian regions (Acarina, Myobiidae)* Kimito Uchikawa Department of Parasitology , Shinshu University School of Medicine, Matsumoto 390, Japan Introduction Through examination of the Miniopterus bats deposited in the big museums in Europe and the United States, it is learned that mites of the genus Calcarmyobia specific to the genus Miniopterus have accomplished more advanced speciation in the Oriental and Australasian regions than in the Ethiopian region, and that all the species of mites from the Oriental and Australasian regions have in common some morphological properties that are different from those shared by the species from the Ethiopian region. The present paper deals with the description and records of mites from Oriental and Australasian Miniopterus. Three species of these mites, C. miniopteris (Womersley), C. hamata Uchikawa et al. and C. australasiae Fain and Lukoschus, have so far been described from Miniopterus in the Oriental and Australasian regions. Twelve new taxa, inclusive of the six new subspecies, are found in the present study, and the number of species and subspecies of Calcarmyobia from these regions is now fifteen. As the records of C. miniopteris were already presented in the preceding paper (Uchikawa, 1985a), the other 14 taxa will be described below. All the specimens came from the bats deposited in collections of AMNH (American Museum of Natural History, New York), BALM (Basel Museum of Natural History, Basel), BSPM (Bishop Museum, Honolulu), BMNH (British Museum (Natural History), London), FMNH (Field Museum of Natural History, Chicago), MNHM (Museum National d'Histoire Naturelle, Paris), ROM (Royal Ontario Museum, Toronto), SMF (Forschungs-Institut Senkenberg, Frankfurt) and USNM (US National Museum, Washington), and they all will be returned to the acarine collections in the respective museums. The scales for all the figures are the same to those in Figs 1-6. Calcarmyobia orianae orianae sp. n., ssp. n. MALE (Figs 1, 2, 3 & 4). Posterior part of setae vi inflated, finely striated and granulated. Setae d very fine, only slightly thicker than ga. Genital shield lacking setae gm and with posterior lobes extending beyond basal level of d 2 ; costal formation closer to base of d 2 than to base of d^\ genital pore situated slightly posterior to basal level of d 2 ; gp stout and pointed. Modified claw on leg II slightly thinner and shorter than normal one and forked. Modified seta on genu II as in Fig. 4; no inflated or thickened setae on tarsus II. Measurements in jim for holotype and, in parentheses, for 5 paratypes and 4 other specimens: Body ( = Gnathosoma + idiosoma) 460 (460-540) long by 210 (205-235) wide. Seta ve 165 (167-180) long; vi 115 (110-115) long; sc e 168 (170-200) long; sc i 60 (58-63) long; ^ 30 (28-32) long; d z 63 (60-70) long; d 3 55 (50-57) long; 7 X 168 (155-183) long; / 3 83 (68-85) long. Genital shield 57 (58-63) long; distance between ga, ga-ga 34 (33-40). Modified setae on genu II 14-17 long. FEMALE (Figs 5 & 6). Seta d l with tail almost the same in length to basal striate part; d 3 originat-ing almost from or slightly anteriad from basal level of / 2 , closer to each other than to / 2 . Basal striated part ofd 2 -d 4 and / 2 rather long and spindle-shaped. Internal anal setae ai clavate. A pair of stout scales with blunt tips laterally on opisthosoma. *Supported financially by Overseas Scientific Research Grant Nos. 57041019 and 5803013 from the Ministry of Education, Science and Culture, Japan.
