越南冷水花属(荨麻科)一新记录种

报道了越南荨麻科(Urticaceae)冷水花属(Pilea Lindl.)一新记录种——基心叶冷水花(P.basicordata W.T.Wang ex C.J.Chen)。该种在越南Pu Hu自然保护区发现,与产自越南北部的P.balansae Gagnep.相似,主要区别在于其雄花序聚伞圆锥状,托叶大,叶先端渐尖或短尾状渐尖。     

Salvia petrophila sp. nov. (Lamiaceae) from north Guangxi and south Guizhou,China

Salvia petrophila G. X. Hu, E. D. Liu & Yan Liu, a new species from the Chinese provinces of north Guangxi and south Guizhou, is described and illustrated. The new species is similar to S. miltiorrhiza, but can easily be distinguished by its shorter, unbranched stem, subsucculent simple leaf, longer pedicel and corolla tube, oblong‐entire middle lobe of lower corolla lip and larger oblate pollen. It is included in S. sect. Drymosphace on the basis of its falcate‐compressed upper corolla lip and connivent posterior connectives. Trichome and pollen micromorphology of the new species and similar species are described and compared. Additionally, assessment of the conservation status, current geographical distribution and notes on ecology of the new species are given.

Three new species of the subgenus Parapenthecia from the Oriental Region (Diptera: Drosophilidae: Apenthecia)

Three new species of the subgenus Parapenthecia of the genus Apenthecia are reported from the Oriental Region: A. (P.) heterochaeta Chen and Toda, sp. nov. from Indonesia, and A. (P.) hispida Chen and Toda, sp. nov. and A. (P.) litongi Cao and Chen, sp. nov. from south China. Interestingly, the last species lacks a very peculiar character, the swollen or scale‐like orbital setae, which are commonly seen in all other species of the genus Apenthecia. A key to all species of the subgenus Parapenthecia is provided.     

Lysimachia vietnamensis and L. verbascifolia spp. nov. (Primulaceae) from Vietnam

Two new species of Lysimachia (Primulaceae), L. vietnamensis L. K. Phan & C. M. Hu and L. verbascifolia C. M. Hu & K. L. Phan from Vietnam are described and illustrated.     

The subgenus Ashima (Diptera,Drosophildae, Phortica) from China,with DNA barcoding and descriptions of three new species

In the present study, three new species found in Yunnan, Southwest China were described as members of the subgenus Phortica (Ashima): P. (A.) haba An & Chen, sp. nov., P. (A.) montipagana An & Chen, sp. nov. and P. (A.) qingsongi An & Chen, sp. nov. Barcode sequences (partial sequences of the mitochondrial COI gene) were collected from 61 specimens of 16 known and the above-mentioned three new Ashima species. The intra- and interspecific pairwise K-2P (Kimura two-parameter) COI distances were analysed and a phylogenetic tree was constructed based on the barcode sequences. Species delimitation in this subgenus was supported by integrating barcodes with morphological information, in particular for the three new species, considered to be cryptic species. In addition, the diversification of lineages in the subgenus Ashima was proposed to occur in southern China and adjacent areas, suggesting specific adaptation of Ashima species to the high plateau environments.

水玉霉(Pilobolus)属的种的重新划分

我们在过去的工作中承认水玉霉(Pilobolus)属的9个种(郑、胡,见戴,1979)。近年来我们重新分离得到了这些分类群并对它们进行了再研究。研究结果表明,尽管它们是彼此可以互相区分的分类群,但是,包括我们过去的概念在内,目前被普遍接受的用于这个属的分类的种概念太小.为了与整个毛霉目的其它属的分类系统相一致,我们把这9个分类群重新划分为由9个变种组成的5个种:晶澈水玉霉原变种[Pilobolus crystallinu (Wigg.) Tode var. crystallinus],晶澈水玉霉透孢变种新组合[P. crystallinus var.hyalosporus (Boedijn) Hu &Zheng, comb. nov.],晶澈水玉霉克莱因变种新组合[P. crystallinus var.kleinii (van Tieghem) Zheng &G.-q. Chen, comb. nov.],豆状水玉霉原变种(P. lentiger Corda var. lentiger),豆状水玉霉小型变种新组合[P. lentiger var. minutus (Speg.) Zheng &G.-q. Chen, comb. nov.],长型水玉霉(P. longipes van Tieghem),厚壁水玉霉(P. Oedipus Mont.),露水玉霉原变种[P. roridus (Bolt.) Pers. var. roridus],露水玉霉突囊变种新组合[P. roridus var. umbonatus (Butler) Hu &Zheng, comb. nov.]。水玉霉属先后报道过的种或种下分类群名称共计50个左右,其中一些异名往往被不同的作者归到不同的正名下面。为了解决它们的正确归属问题,我们对全部原始描述作了细致的文献考证然后决定其位置。对那些找不到原始描述或从原始描述中得不出结论的则作为可疑名称处理。可疑名称共计12个:Mucor obliquus Scop., M. urceolatus Dicks.;Pilobolus urceolatus Purt., P. pestis-bovinae Hallier(=P. hallierii Rivolta), P. nanus van Tieghem, P. intermedius, (Coem.) P. A. Karsten(=P. Oedipus Mont. var,intermedius Coem.), P. pullus Massee, P.proliferens McVickar, P. ramosus McVickar, P. simplex McVickar, P. lentiger forma leinii Reyn. &Laysa, P. lentiger forma minutus Reyn. &Laysa.     

Rhododendron subroseum sp. nov. and R. denudatum var. glabriovarium var. nov. (Ericaceae) from the Guizhou Province,China

One new species, Rhododendron subroseum Xiang Chen & Jiayong Huang, and one new variety, R. denudatum var. glabriovarium Xiang Chen & Xun Chen (Ericaceae), from the Guizhou Province, China are described and illustrated. Rhododendron subroseum is most similar to R. morii from which it differs mainly by having glandular branchlets, a subcordate leaf blade base and a mucronate leaf blade apex, a less floriferous inflorescence, a campanulate to broadly‐campanulate corolla, and a glandular‐hairy style. Rhododendron denudatum var. glabriovarium differs from R. denudatum var. denudatum mainly by having a glabrous ovary. Both of the new taxa are quite rare and therefore their protection is highly desired.     

Saussurea baoxingensis sp. nov. (Compositae,Cardueae) from Sichuan,China

Saussurea baoxingensis Y. S. Chen (Compositae, Cardueae), a new species of snow lotus from the Sichuan province, China is described and illustrated. It belongs to subgenus Amphilaena and is allied to S. muliensis. Morphological characteristics that distinguish the new species from S. muliensis are presented and discussed.     

Revision of the Eastern Asian genera Ambrostoma Motschulsky and Parambrostoma Chen (Coleoptera: Chrysomelidae: Chrysomelinae)

The leaf beetle genera Ambrostoma Motschulsky, 1860 and Parambrostoma Chen, 1934 have been revised and now include 14 species. Two new species from Nepal are described, Parambrostoma kippenbergi sp.n. and P. medvedevi sp.n. Three new synonymies are established: Ambrostoma rugosopunctatum Chen = Ambrostoma (Parambrostoma) laosensis Kimoto & Gressitt, syn.n. , Ambrostoma rugosopunctatum Chen = Ambrostoma daccordii Medvedev, syn.n., Ambrostoma fortunei (Baly) = Ambrostoma quadriimpressum chusanica Gruev, syn.n . One species was transferred from Chrysomela Linnaeus to Ambrostoma Motschulsky: A. superbum (Thunberg), comb.n . All the species now included are described and illustrated. Microcomputer tomography was applied for the first time in a study on chrysomelid beetles. A cladistic analysis based on morphological characters of adults was conducted to reconstruct the intergeneric and interspecific phylogeny of Ambrostoma and Parambrostoma. The results show that the monophyly of both genera is well supported. Ambrostoma is widespread in East Asia, whereas Parambrostoma is restricted to the southern slope of the Himalayas, where a relatively recent and modest speciation took place.

君子峰鸢尾，福建鸢尾科植物一新种

描述了福建省中北部山区鸢尾科(Iridaceae)鸢尾属(Iris)一新种：君子峰鸢尾(I. junzifengensis S. P. Chen, X. Y. Chen&L.Ma),新种与蝴蝶花(I. japonica Thunb.)、台湾鸢尾(I. formosana Ohwi)相近。与蝴蝶花不同之处在于叶片宽大,叶脉明显,表面粗糙;花为顶生稀疏总状聚伞花序,分枝2～6;花大,直径5.0～7.0 cm,花被裂片边缘波状皱褶,全缘,顶端稍有凹缺;蒴果三棱状圆柱形。与台湾鸢尾不同之处在于花小,花被裂片边缘波状皱褶,全缘,顶端稍有凹缺;蒴果三棱状圆柱形。形态特征比较及分子系统发育分析均支持该新种的成立。
