中国树螽亚科两新种(直翅目：螽斯科)
康乐;杨集昆
【期刊名称】《昆虫分类学报》
【年(卷),期】1989(11)3
【摘要】本文记述了树螽亚科Phaneropterinae中安树螽属(Anisotima B.-Bienko,1951)和管树螽属(Ducetia Stal,1874)的两个新种。
这两属在形态上非常相似,但可根据胸足腿节膝片上刺的有无和翅的长宽比来区别。
安树螽属(Anisotima) 所有胸足腿节膝片上均不带刺,前翅较宽,它的长度不及翅宽的4倍。
该属目前仅记载有两种,即A.disparB.-Bienko和A.Yunnanea B.-Bienko,均分布于中国。
本文记述采自浙江的一新种。
管树螽属(Ducetia)所不同的是所有胸足腿节膝片上均带有明显的刺,前翅窄长。

中国蛇根草属(茜草科)二新记录种温兆捷;涂蓉慧;王立彦;吴磊【摘要】报道了中国云南省南部发现的中国蛇根草属(Ophiorrhiza)2新记录种:中泰蛇根草(O.ripicola)和小果蛇根草(O.rosacea),其中后者在中国被错误鉴定为变红蛇根草(O.subrubescens).【期刊名称】《热带亚热带植物学报》【年(卷),期】2019(027)003【总页数】5页(P333-337)【关键词】蛇根草属;新记录;中国;中泰蛇根草;小果蛇根草【作者】温兆捷;涂蓉慧;王立彦;吴磊【作者单位】中南林业科技大学, 生命科学院, 长沙 410004;中南林业科技大学, 林学院, 长沙 410004;云南铜壁关国家级自然保护区, 云南德宏 679313;中南林业科技大学, 林学院, 长沙 410004【正文语种】中文蛇根草属(Ophiorrhiza)是茜草科(Rubiaceae)的一个大属，拥有近300个分类群，广泛分布于亚洲的热带和亚热带地区，少数种类零星分布于澳大利亚、新几内亚和太平洋的一些岛屿上[1–2]。
该属绝大多数种类为草本植物，少数种类因茎干木质化而成亚灌木状。
中国是蛇根草属植物的一个分布中心，拥有约70个分类群，总数占这个属的1/4[1,3–4]。
蛇根草属的果实为倒心形或僧帽状，两侧压扁[3,5–10]，极少为近球形[10]，易与其他属植物区别。
虽如此，该属植物在不同地区的形态特征差异很大[10]，加之多数种类形态描述十分不足[11]，以致关于该属的较为系统的研究到目前为止仅在太平洋岛屿[10]、中国[3]和印度[9]三个地区有过开展。
在标本研究和野外调查中，作者发现采自中国云南的2种蛇根草属植物比较特别，不同于目前中国已记载的蛇根草属种类。
进一步查阅相关文献[1,3,12–15]和研究标本，最终确定该2种蛇根草属植物实为中国的新记录种: 中泰蛇根草(O. ripicola) 和小果蛇根草(O.rosacea)。

因此，实际生产中可在带叶兜兰不同生长阶段接种适当菌株，Phialophora sp.对带叶兜兰表现出较好的促生效应，可研发为带叶兜兰育苗期通用型有益菌剂。

Deng & al. • The new genus Zhengyia (Urticaceae)TAXON 62 (1) • February 2013: 89–9989Version of Record (identical to print version).INTRODUCTIONUrticeae (= Urerareae Wedd.) is a moderately sized tribe of the nettle family (Urticaceae) with eleven genera and ap-proximately 220 species. Its members are often found in humid habitats in forests or at forest margins and occur in both the Old and New Worlds (Friis, 1993; Hadiah & al., 2008; Cohn & Hadiah, 2009). The tribe is characterized by stinging hairs and pistillate flowers with four tepals, of which frequently one pair is larger than the other, and without staminodes (Friis, 1989, 1993). Because of the obvious morphological synapo-morphies of Urticeae, it is not difficult to recognize a plant as being a member of this tribe. Moreover, phylogenetic analysis of Urticaceae using plastid DNA sequence data has shown that Urticeae (including Poikilospermum Zipp.) form a well-supported clade (Hadiah & al., 2008).The Shennongjia National Nature Reserve (SNNR) is lo-cated in the Northwest of Hubei province, central China. Its unique geographical location and complex topology make it one of the most biodiverse areas in China (Ying, 2001; Xie, 2003). The Shennongjia Mountains are characterized by high mountains and deep valleys, a dense network of streams, and lush vegetation. The region is an important hot-spot for south-central Chinese biodiversity and contains many endemic plants (Myers & al., 2000). During our recent in-depth floristic ex-plorations of the SNNR, an unusual taxon caught our attention. The plant was easily identified as belonging to Urticeae based on the presence of stinging hairs, stipules, and pistillate flow-ers with four tepals and without staminodes. In its paniculate inflorescences with many long branches and its four-lobed perianth with larger dorsal than ventral lobes in its female flowers, it superficially resembles Urtica L., a genus of about 30 species with a wide distribution in the northern temperate region (Chen & al., 2003). However, based on its alternate leaf arrangement, the presence of one to three woody bulbils in sterile axils, intrapetiolar stipules in the leaf axils, and oblique achenes with short stipes, we initially assigned the new taxon to Laportea Gaudich., a genus with 30 species confined to tropical and warm-temperate E Asia and eastern North America (Friis, 1993). Upon closer examination, however, it was clear that the set of morphological characters did not match Urtica, Laportea or any other genus of Urticeae (Table 1). The plant is described below as a new genus with only one species, Zhengyia shen-nongensis T. Deng, D.G. Zhang & H. Sun.Bulbils are specialized propagules, allowing vegetative reproduction and dispersal, and many herbaceous plants can produce them (Wang & al., 2004; Walck & al., 2010). Pres-ence or absence of bulbils has been recognized as a significant

Abstract Zhengyia shennongensis is described here as a new genus and species of the nettle family (Urticaceae) from Hubei province, central China. The phylogenetic position of Z. shennongensis is determined using DNA sequences of nuclear ribo-somal ITS and three plastid regions (rbcL, psbA-trnH, trnL-F). Zhengyia shennongensis is readily distinguished from the related genera Urtica, Hesperocnide, and Laportea in the tribe Urticeae by its seed (oblong-globose or subglobose and not compressed achenes, surface densely covered with nipple-shaped protuberances) and stipule morphology (large leaf-like stipules with auriculate and amplexicaulous base and united with stem). Phylogenetic evidence indicates that Zhengyia is a distinct group related to Urtica (including Hesperocnide) species and Laportea cuspidata in tribe Urticeae. The bulbiliferous species of the tribe (L. bulbifera, L. cuspidata, Z. shennongensis) do not form a clade. This result indicates that the bulbil trait evolved in parallel within Urticeae. Our findings highlight the importance of shady and moist habitats in promoting species diversification and the parallel evolution of morphological traits that are likely to be adaptive.
