Seven new trypanosomes are described from Asian cold-blooded vertebrates : 1) Trypanosoma cyrtodactyli detected in Cyrtodactylus quadrivirgatus (Reptilia ; Gekkonidae) from Peninsular Malaysia ; 2) Trypanosoma chalconotae detected in Rana chalconota (Amphibia ; Ranidae) from Peninsular Malaysia and Sarawak ; 3) Trypanosoma kuhlii detected in Rana kuhlii (Amphibia ; Ranidae) from Sarawak ; 4) Trypanosoma sulawesiense detected in Rana celebensis (Amphibia ; Ranidae) from Sulawesi ; 5) Trypanosoma leptobrachii detected in Leptobrachium hendricksoni (Amphibia ; Pelobatidae) from Peninsular Malaysia ; 6) Trypanosoma melanosticti detected in Bvfo melanostictus (Amphibia ; Bufonidae) from Peninsular Malaysia ; 7) Trypanosoma amamiense detected in Cynops ensicauda (Amphibia ; Salamandridae) taken from Amami-Oshima, Japan.
Seventeen species of terrestrial tardigrades of the family Hypsibiidae are recorded, based on the material collected on the northern slope of Mt. Fuji in 1985-1986. They include two new species of the genus Diphascon, a new species of the genus Doryphoribius and a new species of the genus Hypsibius. It is very interesting that Diphascon bidropion sp. nov. has two drop-like thickenings on the wall of buccal tube.
Maraenobiotus veris sp. nov. and Gulcamptus yoichiensis sp. nov. are described from a snowmelt pool of Hokkaido, northern Japan. Maraenobiotus veris is close to Maraenobiotus brucei, and G. yoichiensis is close to Gulcamptus uenoi.
Allorchestes hirsutus sp. nov. is described based on the specimens obtained from floating seaweeds in the Japan Sea. The male of the new species has a weakly hammer-like gnathopod 1, suggesting close relationship to A. carinatus.
Caprella andreae MAYER, 1890, a member of the Caprella acutifrons group, is redescribed on the basis of material from the East China Sea and from Tomioka, Amakusa Island, Kyushu, Japan. In both areas, specimens were collected from the carapace of the loggerhead sea turtle Caretta caretta(L.). Pereopods show a morphological adaptation for clinging to the algal substratum on the turtle carapace. Body robustness as well as other morphological characteristics did not differ between specimens from the two localities. Based on the comparison of morphological characteristics with two other species in the C. acutifrons group, C. andreae may be speciated from the C. acutifrons type origin by adapting to ecologically isolated habitats such as drifting objects.
A new monotypic genus, Tsunogaipagurus, is instituted for a distinct species, Sympagurus chuni (BALSS, 1911). This new genus is distinguishable from other parapagurid genera by the long shield, the extremely large eyes, the palm of the right cheliped provided with numerous distinct tubercles on the ventral surface and the scaphoped shell preference. Tsunogaipagurus chuni is redescribed with illustrations and a note on the living coloration.
The millipede genus Haplogonosoma BROLEMANN, 1916, is a senior synonym of Sphalmatogonus JEEKEL, 1980 (syn. n.), and it seems to actually comprise only two species, H. implicatum BROLEMANN, 1916 (type species), from central Honshu to Kunashir Island, Kuriles, and H. silvestre TAKAKUWA, 1942 (=H. silvestre dichotomum TAKAKUWA, 1942, =Sphalmatogonus carli JEEKEL, 1980, both syn. n.), at least from Kyushu and ?Sumatra. The systematic position of Haplogonosoma is discussed, and the genus is formally allocated within the chiefly Papuan tribe Eustrongylosomatini.
New material from Sichun, Hunan and Anhui, China, proves that Leptoteratura omeiensis (TINKHAM, 1956) is a junior synonym of L. albicornis (MOTSCHULSKY, 1866). A new species, L. borneoensis JIN, from North Borneo is described, which is close to L. symmetrica YAMASAKI, 1988.
