Additional Records of Digenetic Trematodes of Birds from Taiwan

43 species of digenetic trematodes of birds are reported from Taiwan. One new family, one new subfamily, two new genera, and nine new species are described: Taiwantrematidae fam. n. Taiwantrema arborophilae gen. et sp. n. from Arborophila crudigularis; Cyclocoelidae, Morishitium taiwanense sp.n. from A. crudigularis; Eucotylidae, Tanaisia (Tamerlania) taiwanensis sp. n. from A. crudigularis; Brachylaimidae, Leucochloridium taiwanense sp. n. from A. crudigularis; Echinostomatidae, Echinostoma taiwanense sp. n. from Zosterops japonica simplex; Dicrocoeliidae, Concinnum taiwanense sp. n. from Pycnonotus taivanus; Lecithodendriidae, Pseudocryptotropa formosae sp. n. from Pycnonotus sinensis formosae; Microphallidae, Promicrophallinae subfam. n. Promicrophallus taiwanensis gen. et sp. n. from A. crudigularis; Opisthorchiidae, Metametorchis taiwanensis sp. n. from the domestic duck.     

中华花龟消化道5-羟色胺免疫活性内分泌细胞的分布与形态学观察

应用5-HT抗血清,以ABC（avidin-biotin-peroxidase complex）免疫组织化学方法,探究中华花龟消化道内5-HT免疫反应阳性内分泌细胞的分布及形态。结果表明,5-HT阳性细胞从食管到直肠的消化道各段均有分布,以十二指肠部位分布密度为最高,胃幽门部次之,食管部最低;5-HT阳性细胞广泛分布于上皮细胞之间、上皮基部、腺泡上皮细胞之间、腺泡之间以及固有膜内,形态多样呈圆形、椭圆形、锥体形、梭形等,以锥体形为主。认为中华花龟消化道5-HT阳性细胞具有内、外分泌两种作用途径,并且5-HT阳性细胞的密度分布可能与其食性、生活环境等有关。     

Pathogenicity of Spiroplasma taiwanense for larval Aedes aegypti mosquitoes

Helical replicative forms, but not the persistent non-replicative forms, of Spiroplasma taiwanense Abalain-Colloc et al. (isolated from the mosquito Anopheles sinensis Wiedemann in Taiwan) were shown to reduce significantly the survival of Aedes aegypti (L.) mosquito larvae reared in 10 ml of water with 0.3 ml of S.taiwanense suspensions added on days 0 and 3. The suspensions contained, respectively, helical forms at a concentration of 10(9) Colour Change Units (CCU)/ml and persistent forms at 10(6) CCU/ml. It is suggested that S.taiwanense, or toxins produced from it, are potentially useful for use in integrated mosquito control programmes.

A taxonomic revision of the genus Sinotrisus Yin & Li (Coleoptera, Staphylinidae, Pselaphinae)

The genus Sinotrisus Yin & Li, comprising four species, is redefined and revised. Members of Sinotrisus are often found with ants of the subfamily Formicinae, or in humid forest habitats. The type speciesand three new species are (re-)described and illustrated: Sinotrisus kishimotoi Yin & Nomura, sp. n. (China: Sichuan), Sinotrisus nomurai Yin, Li & Zhao (type species) (China: Zhejing), Sinotrisus sinensis Yin & Nomura, sp. n. (China: Sichuan) and Sinotrisus vietnamensis Yin & Nomura, sp. n. (Vietnam: Lai Chau). A key is included as an aid to distinguishing these species.     

A new species of Macrobothriidae (Cestoda: Diphyllidea) from thornback ray Platyrhina sinensis in China

A new cestode, Macrobothridium sinensis n. sp., is described from the spiral intestine of Platyrhina sinensis from coast of Xiamen, China. It is the first record of the order Diphyllidea in China. The new species can be distinguished from the 3 previously described species of Macrobothridium by the testes number (16-24 vs. 29-37, 27-46, and 5-6, in M. rhynchobati, M. euterpes, and M. syrtensis, respectively) and a single-row arrangement of testes; M. sinensis is most similar to M. euterpes in strobila length (1.77-6.23 vs. 2-4.5 mm) and number of segments (6-8 vs. 5-9). In addition, M. sinensis differs from M. rhynchobati and M. syrtensis in the strobila length, ovary shape, and number of apical hooks. The uterine pore is the first described in the Diphyllidea; thus, the present uterine pore can now be used to distinguish Macrobothridium from Echinobothrium and Ditrachybothridium in the Diphyllidae.     

Six new species of palaeonemerteans (Nemertea) from Hong Kong

One new genus and six new species of palaeonemerteans are described and illustrated from Hong Kong and the New Territories; these are Hubrechtella sinimarinus sp. nov. and Parahubrechtia jillae gen. et sp. nov. in the Hubrechtidae, and Callinera bergendali sp. nov., Carinina sinensis sp. nov., Tubulanus hylbomi sp. nov. and Tubulanus longivasculus sp. nov. in the Tubulanidae. These bring the known number of pa-laeonemertean species from Hong Kong to 11; a key to these species, based primarily upon features distinguishable in the living animals, is provided.     

Determination of the anamorph of Cordyceps sinensis inferred from the analysis of the ribosomal DNA internal transcribed spacers and 5.8S rDNA

The anamorph determination of Cordyceps sinensis remains problematic due to the lack of clear links between the sexual and conidial forms of the fungus. In this study, we applied molecular approaches to analyze the genetic variation of Cordyceps sinensis and its allies to identify the anamorph-teleomorph connection. The sequences of the internal transcribed spacers (ITS1 and ITS2) and 5.8S ribosomal RNA gene of Cordyceps sinensis (teleomorph) collected from Qingzang plateau (altitude over 4000m), Tibet and several related asexual conidial forms were determined. The sequence comparison showed that Cordyceps sinensis was most closely related to Hirsutella sinensis, and was clearly divergent from Paecilomyces sinensis, Stachybotrys sp. or Tolypocladium sp.; distance values, estimated according to Kimura two-parameter models between Cordyceps sinensis and Hirsutella sinensis, were extremely low (<0.02), whereas distance values between Cordyceps sinensis and Paecilomyces sinensis, Stachybotrys sp. and Tolypocladium sp. were 0.34, 0.21 and 0.25, respectively. Taken together, Hirsutella sinensis and Cordyceps sinensis are the different stages of the life cycle stages of the same organism. Hirsutella sinensis is therefore the anamorph of Cordyceps sinensis, rather than Paecilomyces sinensis or other species. The possible reasons as to why different taxa can be obtained when culturing Cordyceps sinensis are also discussed.

甘肃董湾晚新近纪地层及中新统/上新统界线

古地磁测年表明,甘肃董湾晚新近纪剖面代表了7.3～3.5 Ma间的连续风成古土壤堆积。在74.8 m厚的剖面上,发现了小哺乳动物化石层位40个,共产出小哺乳动物39种。根据小哺乳动物组合特点,董湾剖面可以划分出4个生物地层带,Ⅰ+Ⅱ带为晚中新世晚期,相当于保德期;Ⅲ+Ⅳ带为上新世早期,相当于榆社期早期。中新统/上新统界线(5.33 Ma)位于剖面距顶部35.5 m处,比以鼢鼠Mesosiphneus最早出现为标志的生物地层Ⅲ带的底界低2 m。由于榆社阶底界直接对应于中新统/上新统界线,该剖面因其良好的地层和生物条件可被推荐为榆社阶界线层型的候选剖面。     

On a new species of Keratella (Rotifera: Monogononta: Brachionidae)

中国拟青霉新种及其与虫草的关系

从虫草[Cordyceps sinenisis(Berk.),Sacc.]上分离到中国拟青霉新种(Paecilomyces isnenisisp.nov.),对它进行了培养和形态学研究。中国拟青霉与蛹草[cordyceps militaris(L·)Liak]的无性阶段形态非常类似,但在分生孢子形态,分生孢子和瓶梗的量度上有所不同,且两者的寄主及生境不同,故定为新种。不仅可从长子座的殭虫获得其纯培养物,也可从不长子座而长孢梗束的虫草纯化培养获得。纯培养物的形态和天然虫体的孢梗束完全相同,故认为它可能是虫草的无性阶段。
