Jinggang) Clubiona expansa Huang & Chen, 2012: 55, f. 15A–G. (male holotype; 1 male and 1 female paratypes from China, Taiwan Province, New Taipei City). Syn. N. Material examined. CHINA: Taiwan, New Taipei City, District Pinglin (24o55’55.78"N, 121°42′41.10"E, 210m), 19 July 2013, F. Liu and W.Gan leg., 1 male (HUBU-TW- 130177) and 1 female (HUBU-TW- 130178); Guizhou, Mt. Fanjing, Taiping village (24o55’55.78"N, 121o42’41.10"E, 634m), 24 May 2015, M. Yan and J.Li leg., 1 female (HUBU-GZ- 150249). Diagnosis. Pristidia ramosa can be easily distinguished from P. cervicornuta sp. nov. by the embolus distinctly longer, the presence of basal teeth on the RTA, RTA expanded, with a blunt tip, and by the absence of TA (Figs 13, 14). Yu, Sun & Zhang (2012: 45) highlighted the differences of this species from P. prima. Description. See Yu, Sun & Zhang (2012). Intraspecific variation. There is almost no difference between the male from Taiwan (HUBU-TW- 130177, Figs 10, 12–14) and the holotype from Jiangxi (Yu, Sun & Zhang 2012: figs 1–7, 12–14). However, some intraspecific variation is exhibited by females from different localities, mostly related to different degrees of sclerotization. The female from Taiwan (HUBU-TW- 130178, Fig. 11) is distinctly larger in size and darker in color than the paratype from Jiangxi (Yu, Sun & Zhang, 2012: fig. 8). Furthermore, in HUBU-TW- 130178, the epigynal ventral plate is more sclerotized (Fig. 15) than in the paratype (Yu, Sun & Zhang 2012: fig. 9); both spermathecae and bursae are totally transparent in HUBU-TW- 130178 (Fig. 16), while more sclerotized in the paratype (Yu, Sun & Zhang 2012: figs 10, 16). Natural history. The spiders inhabit forests in low mountain areas (210–800 m). This is in accordance with data of the type locality provided by Yu, Sun & Zhang (2012) and Huang & Chen (2012). Distribution. Mt. Jinggang in Jiangxi, Mt. Fanjing in Guizhou and New Taipei City in Taiwan, China. The present data showed the extension of the known range of this species of about 560 km to the northwest (Mt. Fanjing) and of 750 km to the southeast (Taiwan) from the type locality (Fig. 17). Remark. Although we have not examined the type specimens of C. expansa, the long filiform embolus, the expanded RTV with a subapical flange, the bell-shaped atrium, and the course of vulvar duct system shown in the original illustrations (Huang & Chen 2012, fig. 15A–G), leave no doubts on this synonymy. Huang & Chen (2012) was published in May, 2012 (day of publication not specified), while Yu, Sun & Zhang (2012) was published in May, 3, 2012. According to the article 21.3 of the International Code of Zoological Nomenclature, the publication date of Huang & Chen (2012) must be specified as May, 31, 2012. Consequently, C. expansa is here considered as a junior synonym of P. ramosa.Published as part of Yu, Hao, Zhang, Jianshuang & Chen, Jian, 2017, Taxonomy of the genus Pristidia Deeleman-Reinhold, 2001 (Araneae: Clubionidae) in China, pp. 411-418 in Zootaxa 4306 (3) on pages 413-416, DOI: 10.11646/zootaxa.4306.3.7, http://zenodo.org/record/84452

Macrostomum bicaudatum Wang, Sun & Zhang, n. sp.
No full text<i>Macrostomum bicaudatum</i> Wang, Sun & Zhang, n. sp. <p>(Figs.10–11)</p> <p> <b>Material examined.</b> Holotype (PLA-Ma00024): permanent slides of specimen stained by the H.E. method. Paratype (PLA-Ma00025~00027): permanent slides of specimen stained by the H.E. method. All specimens are deposited in IZCAS. A dozen of <i>M. bicaudatum</i> <b>n. sp.</b> were collected from dead leaves at the bottom of an artificial lake of Shenzhen University campus (22°31' 44"N, 113°55' 52"E) (Fig.1) in December 2006, at the water depth of about 80 cm. Lotuses, as well as other aquatic plants, fishes, snails, shrimp and zooplankton were originally transferred from a wetland of Foshan City, Guangdong Province, China when this artificial lake was constructed. This species was also found by the authors on July 20, 2014 at the root of a water hyacinth in a tributary of Dongjiang River, Huizhou, Guangdong Province (23°8' 59.74"N, 114°22' 26.27"E, altitude 14 m, water temperature 24°C, pH 7.65).</p> <p> <b>Etymology.</b> The specific epithet refers to the shape of the tail end of this new species, which is of a fishtail shape.</p> <p> <b>Description.</b> The body is flat. The length and width of its body is 1000.8 ± 210.8 µm (n = 4) and 259 ± 59.7 Μm (n = 4), respectively. Its head is bluntly round and the tail has 2 lappets arranged in a fishtail shape (Figs. 10 A and 11A). It has dense and short rod-like adhesive glands (ad) (Figs. 10 C and 11A).</p> <p> <i>M. bicaudatum</i> <b>n. sp.</b> is hermaphroditic. The false vesicula seminalis (fvs), vesicula seminalis (vs) and vesicula granulorum (vg) are arranged in a lateral triangle shape (Figs. 10 A & B, 11A & B). The penis stylet (ps) bends from the right side to the left side planimetrically, and then bends to the male gonopore (mg) in an auricle-shape (Figs. 10 B, 11B–D). The curved-line (marked as ‘a’) and straight-line (marked as ‘b’) distances between the base and distal end of penis stylet (ps) are 160 ± 3.05 Μm (n = 3) and 70 ± 6.01 Μm (n = 3) (Fig. 4 D). The diameters of basal and distal parts of penis stylet (ps) are 11 ± 0.35 Μm (n = 3) and 4 ± 0.6 Μm (n = 3), respectively. The upper margin of the distal part is longer than the lower margin, while the horseshoe-shape lower margin is thickened (Figs. 10 B, 11B–D). The features of the female reproductive system are identical to those of other species within the genus of <i>Macrostomum</i>.</p> <p> <b>Remarks.</b> <i>Macrostomum bicaudatum</i> <b>n. sp.</b> is most similar to <i>M. phocorum</i> Marcus, 1954 in external morphology and <i>M. semicirculatum</i> Ax, 2008 in penis stylet morphology. However, <i>M. phocorum</i> is much bigger, with a length of 1,500 Μm and width of 300 Μm. It has a rounded head, and the tail is bifurcated with affiliated adhesive glands (ad) at the tip. Its penis stylet (ps) is matroos pipe-shaped. In contrast, the tail of <i>M. bicaudatum</i> <b>n. sp.</b> is bifurcated and its penis stylet is in auricle-shaped. Therefore, although similar in external features, the two species differ in body size as well as morphology of the penis stylet.</p> <p> In <i>M. semicirculatum</i> Ax, 2008, the penis stylet (ps) is bent in a semicircular-shape. The diameters of basal and middle parts of penis stylet (ps) is 20 Μm and 3~4 Μm, respectively. The base of penis stylet (ps) is funnel-shaped. The tail of <i>M. semicirculatum</i> is arc-shaped. In contrast, the penis stylet (ps) of <i>M. bicaudatum</i> <b>n. sp.</b> is auricleshaped. As a whole, it is much slender than the penis stylet of <i>M. semicirculatum</i>, and is slightly swollen at anterior 1/10 position of the base region. The tail has 2 significant fishtail-shape lappets. Therefore, it differs remarkably from <i>M. semicirculatum</i> morphologically.</p> <p> <b>Discussion.</b> The taxonomic study of Chinese turbellarians started relatively late. At the end of the 20th century, only 21 species of freshwater turbellarians were recorded (Zhao <i>et al.</i> 2011). Since the 21st century, 30 more species of turbellarians have been described, including 18 species of Rhabdocoela (Wang 2004; Wang & Li 2005; Wang & Wu 2005a, 2005b; Wang & Deng 2006; Wang & Wu 2008; Zhang <i>et al.</i> 2010; Wang & Sun 2011; Lai <i>et al.</i> 2014; Lu <i>et al.</i> 2013; Xia <i>et al.</i> 2014; Zhang <i>et al.</i> 2014), 3 species of Tricladida (Yu <i>et al.</i> 2013; Chen <i>et al.</i> 2015a; Chen <i>et al.</i> 2015b), 2 species of Prolecithophora (Gao <i>et al.</i> 2011; Ma <i>et al.</i> 2014), 1 species of Lecithoepitheliata (Peng <i>et al.</i> 2007), 1 species of Acoela (Sun & Wang 2014), and 6 species of <i>Macrostomum</i> (Wang <i>et al.</i> 2004, Wang & Luo 2004; Wang 2005; Zhao <i>et al.</i> 2011).</p> <p> <i>Macrostomum</i> inhabits a variety of habitats including clean to eutrophic, and freshwater and marine waters. In this contribution, all specimens of the three new species were collected in pollution-free freshwater environments. Among the <i>Macrostomum</i> that have been described in China, <i>M. intermedium</i> (Tu, 1934) has been reported from a pond of Tsinghua University, Beijing only; <i>M. tuba</i> (Wang <i>et al.</i>, 2004) is widely distributed in Anhui, Guangdong and Fujian provinces; <i>M. xiamensis</i> (Wang & Luo 2004) is distributed in Xiamen; <i>M. sinensis</i>, <i>M. acus</i> and <i>M. obtusa</i> (Wang 2005) are distributed in Guangdong; <i>M. saifunicum</i> (Zhao <i>et al.</i> 2011) is widely distributed in Beijing, Anhui, Hunan, Jiangxi and Guangdong. The above 7 species of <i>Macrostomum</i> were all collected from pollution-free habitats with highly diverse aquatic invertebrates. In terms of biogeographic distribution, <i>M. intermedium</i> is distributed in the Palaearctic region; and <i>M. saifunicum</i> and <i>M. tuba</i> are distributed worldwide. The other 4 <i>Macrostomum</i> species and the three new species in this study are all distributed in the freshwater areas of the Oriental region. Due to rapid population expansion and economic development, the local distribution of these <i>Macrostomum</i> species is restricted to protected water zone and the brooks in remote areas, which suggests that they are susceptible to the widespread pollution of freshwater environment. The three new species reported in this study are all originated from southern China, a subtropical area with highly diverse plants and animals. Therefore, further investigation on the diversity of turbellarians is warranted in the future study.</p>Published as part of <i>Sun, Ting, Zhang, Lv, Wang, An-Tai & Zhang, Yu, 2015, Three new species of freshwater Macrostomum (Platyhelminthes, Macrostomida) from southern China, pp. 120-134 in Zootaxa 4012 (1)</i> on pages 128-131, DOI: 10.11646/zootaxa.4012.1.6, <a href="http://zenodo.org/record/234683">http://zenodo.org/record/234683</a>
Sun Wen and Zhang Zuolin, Focusing on Their Partnership for the Reunification of the Republic of China
No full textSun Wen's reconciliation with the Beijing government in the 1920s has often been regarded as an aberration for Sun as a revolutionary. The author, however, considers it a practical policy aimed at reunifying the Republic of China. This article attempts to clarify what impelled Beijing and Sun to collaborate, and to review how they evaluated one another and what they expected from the reconciliation. Emphasizing Sun's partnership with Zhang Zuolin, who reigned supreme in Beijing after 1924, I concentrate on the relation-building process between the two. Section 1 covers the period from 1911 to 1918 when there was no room for cooperation. During this period, Sun regarded Zhang as an enemy of the revolution and the republic. However, Sun gradually discovered that Zhang would be useful in influencing the rivalries in Beijing among Duan Qirui, Cao Kun, and Wu Peifu. Section 2 adresses the international necessity for reunification of the Republic due to the end of World War I in 1918, and the changes involving the Beijing Government and Sun. In this period, Duan and Sun sought to collaborate. However, Zhang sided with Cao and Wu and won the backing of Japan, becoming the most powerful military leader Sun could find. After Duan lost Anhui-Zhili War in 1920, Sun was threatened by Cao and Wu, and seeking a military partnership, entered into secret negotiation with Zhang. Analyzing the memoir of Ning Wu, who was in charge of the negotiations and Sun's correspondences from 1922-23, I examine the relationship-building process in section 3. Sun planned joint operations with Zhang in the First Fengtian-Zhili War in 1922 but failed due to poor timing, and Zhang lost the war. However, Sun maintained the plan, built up a network of connections, and secured loans for the military from Zhang. In conclusion, Sun decided to take a conciliatory attitude toward Duan and Zhang based on the necessity of reunifying the Republic. After Duan's loss in the civil war of 1920, Sun regarded Zhang, who had greater military power, as the most significant partner. Securing war funding from Zhang provided Sun the opportunity to exercise influence on the military and political situation in the north
