中国脊椎动物2020年新增物种

为了及时掌握中国脊椎动物新增物种情况, 本文系统检索和整理了2020年发表的分类学文献, 汇总结果表明: 2020年中国脊椎动物共新增109种, 其中新物种100种, 国家级新记录种9种。包括鱼类新种24种、两栖类新种41种和新记录4种、爬行类新种30种和新记录4种、鸟类新种1种、哺乳类新种4种和新记录1种。上述新增物种中有92种描述报道时应用了分子遗传学证据, 占新增物种数量的84.4%。在新增脊椎动物物种中, 两栖类集中于无尾目、爬行类全部属于有鳞目, 分别有43种和34种, 其累计占比超新增物种总数的70%。在云南、西藏、湖南、贵州、四川等省区发现新物种数量较多, 均有10种及以上, 累计占比超新增物种总数的60%。绝大部分物种为中国学者发表, 绝大多数论文发表于英文期刊。总结数据提示今后需持续加强我国低等脊椎动物多样性的调查研究, 重视运用分子系统学技术进行物种识别。     

广东省种子植物分布新资料(二)

报道广东省种子植物分布新记录5种——竹茎兰(Tropidia nipponica Masam.)、二色鸭跖草(Commelina bicolor D. Q. Wang & M. E. Cheng)、猫爪草(Ranunculus ternatus Thunb.)、繁缕景天(Sedum stellariifolium Franch.)和福参(Angelica morii Hayata),均发现于广东丹霞山国家级自然保护区。新记录不仅丰富了广东省的种质资源,对于丹霞山的区系发生研究也具有一定指示意义。     

贵州省藜芦科一新记录属——白丝草属

报道贵州省藜芦科一新记录属——白丝草属Chamaelirium Willd.,一新记录种——中国白丝草Chamaelirium chinense (K. Krause) N. Tanaka,并对该种的形态特征、生境、分类变动进行描述及讨论。     

福建省被子植物新记录属种

报道福建省被子植物新记录1属--球子草属(Peliosanthes Andr.)和新记录2种,即百合科(Liliaceae)大盖球子草(Peliosanthes macrostegia Hance)和花柱草科(Stylidiaceae)花柱草(Stylidium uliginosum Swartz),凭证标本保存于福建农林大学标本馆(FJFC)。     

中国藓类植物一新记录种——多齿悬藓

报道了产自西藏墨脱的中国悬藓属新记录种——多齿悬藓（Barbella horridula Broth.）。多齿悬藓曾报道产于印度尼西亚（苏门答腊岛）和菲律宾（吕宋岛）,经与模式标本比较,该标本仅在叶中部细胞和角细胞的分化程度上与模式标本略有不同。该种的茎叶为狭卵状披针形,叶中部细胞较长及边缘具明显的齿,可与同属国内其它种相区别。该文对多齿悬藓的形态特征进行了详细描述并提供了显微形态照片,编制了中国悬藓属植物分种检索表。     

新疆芦荟藓属的分类及分布

以采自新疆各地的350余份芦荟藓属植物为材料,对新疆芦荟藓属植物的分类及其分布进行研究。结果显示,新疆产芦荟藓属植物3种：短喙芦荟藓（Aloina brevirostris（Hook.&Grev.）Kindb.）、斜叶芦荟藓（A.obliquifolia（Müll.Hal.）Broth.）和钝叶芦荟藓（A.rigida（Hedw.）Limpr.）。其中斜叶芦荟藓为新疆新记录种。对它们的形态特征进行了描述,明确了各种的识别特征,并提供了生境、产地与分布地等信息及显微照片,编制了新疆芦荟藓属植物分种检索表。     

Evolution of antennules of cytheroidean ostracods (Crustacea)

Phylogenetic analysis and fossil records indicate that antennules with whip-like setae are the most plesiomorphic state in cytheroidean ostracods and that antennulae with claw-like setae are derived from antennulae with whip-like setae. Character distributions on the 18S rDNA molecular phylogenetic tree suggest that two phenotypic features of cytheroidean antennules (W/L ratio and claw-like/whip-like setae) have morphological plasticity. These features have evolved as an ethological adaptation rather than due to phylogenetic constraints such as the evolution of shell outline in cytheroideans. However, the species of the Leptocytheridae–Trachyleberididae clade generally have stout, robust antennules, indicating a phylogenetic constraint. The character state of setae (claw/whip) in cytheroidean ostracods is reflected more through their ethology than the W/L ratio of the antennules. On the basis of the present analysis and the fossil record, diversification in the morphology of the antennules seems to have occurred during the early Mesozoic.     

Two new species of Abernessia Arlé (Pompilidae,?Ctenocerinae)

Two new species are added to the rare pompilid genus Abernessia Arlé. Abernessia capixaba sp. n. and A. giga sp. n. are described and illustrated. This is the first record of the genus from the states of Espírito Santo and Minas Gerais, Brazil. The genus now contains four species. A brief discussion of generic characters, illustrations, and a key to the known species of Abernessia are provided.     

A taxonomic study on the genus Harpapion Voss, 1966 from China (Coleoptera,Apionidae)

Harpapion safranum sp. n. and Harpapion borisi sp. n. are described and figured. Harpapion vietnamense (Korotyaev, 1987) is recorded as new for China. The genitalia andterminalia of H. considerandum, H. coelebs andH. vietnamense are redescribed and redrawn. The diagnostic characters of Harpapion are defined. A key to the known species of the genus Harpapion from China is provided. Affinities with the genus Flavopodapion Korotyaev, 1987 are discussed.
