Micromisumenops Tang & Li 2010, gen. nov.
No full textMicromisumenops gen. nov. Type species. Misumenops xiushanensis Song and Chai, 1990 (♂). Etymology. The generic name is a combination of Greek prefix micro - (means small, tiny) and Misumenops (Latinized from Greek), refers to the small sized genus which is similar to Misumenops O. P.-Cambridge, 1900; masculine in gender. Diagnosis. Species of this genus can be separated from Misumenops (and other genera of Misumenini Simon, 1895) by: 1) the procurved AER and recurved PER (both recurved in Misumenops); 2) the small body size: ♂ 2.20– 2.30, ♀ 2.75–3.17 (usually larger body size in Misumenops); 3) the flat, caudally truncated opisthosoma in the female (opisthosoma slightly swollen, caudally sharp in Misumenops); and 4) the transverse, spatulate-shaped RTA (usually vertical in Misumenops) in the male, epigynum without hood in the female. Description. See description of Micromisumenops xiushanensis. Species included. Only the type species. Remarks. This type species was placed provisionally in Misumenops by Song and Chai (1990: 370, figs 9A−E). The generic status of this species was questioned in subsequent study (Lehtinen 2005: 177). We followed Lehtinen and established Micromisumenops gen. nov. to accommodate this species.Published as part of Tang, Guo & Li, Shuqiang, 2010, Crab spiders from Xishuangbanna, Yunnan Province, China (Araneae, Thomisidae) 2703, pp. 1-105 in Zootaxa 2703 on page 3

Biacanthus pleuronichthydis (Yamaguti, 1939) comb. n. Etymology. The generic name is a composite of the Latin bi (= two) and acanthus (= a common suffix in the Taeniacanthidae, meaning spine), alluding to the powerful uncinate process posterior to the antennule bases.

The presence of a horseshoeshaped, sclerotised structure on the ventral surface of the rostrum and a robust uncinate process posterior to each antennule base are the two most distinctive characters of adult B. pleuronichthydis. According to Izawa (1986), the ventral side of the rostrum of B. pleuronichthydis undergoes considerable morphologic changes throughout the copepodite stages. For instance, a large median hook develops in the first copepodite, but is absent in the next copepodite stage. In the third to fifth male copepodites, as well as the third and fourth female copepodites, the rostrum bears a small anteroventral sclerotised projection. The projection is lost and the horseshoeshaped structure develops in the adult stages. In contrast to the rostral area, the uncinate processes are present in all copepodite stages, except for the first copepodite (Izawa, 1986). It should be noted that male Taeniacanthodes haakeri Ho, 1972 and female Anchistrotos caligiformis (Gurney, 1927) have one and two pairs, respectively, of small spiniform processes situated posterior to the antennule. However, these structures are not homologous with the uncinate processes of B. pleuronichthydis.Published as part of Tang, Danny & Izawa, Kunihiko, 2005, Biacanthus pleuronichthydis (Yamaguti, 1939) gen. n., comb. n.

Spilosynema Tang & Li 2010, gen. nov.
No full textSpilosynema gen. nov. Type species. Spilosynema ansatum sp. nov. Etymology. The generic name is a combination of Greek noun spil - (means spots or patterns) and Synema (latinized from Greek), referring to the similarity of this new genus to Synema Simon, 1864, and its characteristic cover of the dorsal opisthosoma with unique white spots; neuter in gender. Diagnosis. Species of this genus can be easily distinguished from other genera of Thomisidae by the characteristic markings on dorsal opisthosoma. This genus is easily confused with Synema and Lysiteles in general appearance. It can be separated from Synema Simon, 1864 by: 1) flat opisthosoma (globular opisthosoma in Synema); 2) metatarsi and tibiae I, II with few hairs (dense hairs in Synema); 3) PER more recurved than in Synema; 4) opisthosoma dorsally with characteristic white spots (large yellowish white patterns and grayish brown markings in Synema). This new genus can be separated from Lysiteles Simon, 1895 by: 1) opisthosoma with characteristic white spots (various style of markings in Lysiteles); 2) large body size: ♀ 3.10–5.00, ♂ 2.90–4.00 (small in Lysiteles: ♀ 2.00–4.20, ♂ 1.80–3.60); 3) the ratio of width of eye area / prosoma = 0.60 (0.80 in Lysiteles); 4) prosoma less swollen than in Lysiteles. Description. Small to median size. Prosoma flat, dorsally with a pair of grayish black stripes, sides grayish black, eye tubercles grayish white, PER strongly curved, ALE>PLE>AME>PME. Legs with long spines, leg formula: 2143. Opisthosoma dorsally with characteristic white spots. Cymbium with tutaculum; palp with VTA, some species with ITA and RTA; bulb flat, embolus slender; epigynum usually with a median sclerotized plate; copulatory ducts long, twisted; spermathecae short, convoluted. Species included. Spilosynema ansatum sp. nov.; S. comminum sp. nov.; S. mancum sp. nov. and S. ravum sp. nov. Habitat. Specimens were collected by fogging from tropical forest of Xishuangbanna. Distribution. China (Yunnan). Remarks. It is noteworthy that more adult than juvenile specimens of this genus were collected during November–December, 2009 from Xishuangbanna. The species Synaema nangoku Ono, 2002 from Japan could be a member of this genus judging by the illustrations (Ono 2002).Published as part of Tang, Guo & Li, Shuqiang, 2010, Crab spiders from Xishuangbanna, Yunnan Province, China (Araneae, Thomisidae) 2703, pp. 1-105 in Zootaxa 2703 on page 6

Cepolacanthus Maran, Moon, Adday & Tang, 2016, gen. nov.
No full textCepolacanthus gen. nov. Diagnosis. Adult female. Body elongated. Prosome composed of cephalothorax (cephalosome fused with first pediger) and three free pedigerous somites. Urosome composed of fifth pedigerous somite, genital somite, and three free abdominal somites. Caudal ramus bearing seven setae. Rostrum well developed. Antennule 6-segmented, with armature formula 5, 15, 8, 4, 2 + 1 aesthetasc, 7 + 1 aesthetasc. Postantennal process present. Antenna 3- segmented, composed of coxobasis and two endopodal segments; distal endopodal segment bearing two pectinate processes, three claws and five setae. Labrum broad, ornamented. Mandible 1-segmented, with accessory seta and two terminal blades. Paragnath digitiform, ornamented. Maxillule lobate, armed with five setae. Maxilla 2- segmented, composed of syncoxa and basis; latter tapering into serrated process and bearing two unequal, separated elements. Maxilliped 3-segmented, composed of syncoxa, basis and long terminal claw (endopod). Legs 1–4 biramous. Leg 1 lamelliform, consisting of coxa, basis and 2-segmented rami. Legs 2–4 each with 3- segmented exopod and 2-segmented endopod; third exopodal segment of leg 4 with large distolateral protuberance. Leg 5 uniramous, 2-segmented, composed of protopod and 1-segmented exopod; exopod bearing one seta and three spines. Leg 6 vestigial, bearing three setae in egg sac attachment area. Adult male. Unknown. Type and only species. Cepolacanthus kimi sp. nov. Etymology. The generic name is an amalgamation of cepola (= suffix of the host genus Acanthocepola) and the Latin acanthus (= spine), a common suffix used in the formation of generic names in the Taeniacanthidae. Remarks. Cepolacanthus gen. nov. is assigned to the Taeniacanthidae because it possesses a postantennal process, two pectinate processes plus setae and clawlike spines on the antennal endopod, at least two spinulated blades on the mandible, a spinulated terminal process on the maxilla, and a lamelliform leg 1, with an outwardlydirected endopod bearing setae along the inner margin (Dojiri & Cressey 1987; Huys et al. 2012). The taeniacanthid maxilla is 2-segmented and primitively bears a maximum of four elements on the distal segment. In the great majority of taeniacanthids, the distal segment of the maxilla bears only one seta and two spinulated spines, one of which is invariably fused to the terminal segment, forming what is known as a terminal process (Dojiri & Cressey 1987). More importantly, the seta is usually positioned on the same transverse plane as the free spinulated spine (Dojiri & Cressey 1987: Figs. 59H, 128D, 146G). In Cepolacanthus gen. nov., however, the relative positions of the two free maxillary elements are unique in that the seta is displaced more proximally on the terminal process than the spinulated spine. The vast majority of taeniacanthids possess a 3-segmented endopod on legs 2–4. By contrast, Cepolacanthus gen. nov., Taeniacanthus mcgroutheri Tang, Uyeno & Nagasawa, 2011a, Saging cebuana Uyeno, Tang & Nagasawa, 2013 and members of Umazuracola Ho, Ohtsuka & Nakadachi, 2006 all have a 2-segmented endopod on legs 2–4. This derived character state stems from the failure of the middle and terminal segments, rather than the proximal and middle segments, to separate. Cepolacanthus gen. nov. differs markedly from T. mcgroutheri, S. cebuana and Umazuracola spp. in having: 1) a relatively smaller rostrum which bears sclerotized structures on the ventral surface; 2) plumose (vs. naked) setae on antennulary segments 1–4; 3) an accessory seta (vs. none) on the mandible; 4) eight (vs. six) elements on the terminal exopodal segment of legs 2–3; 5) seven (vs. six) elements on the terminal exopodal segment of leg 4; 6) spinulated (vs. setiform) spines on the exopod of leg 4; and 7) three spines and one seta (vs. four setae) on the free exopodal segment of leg 5. Cepolacanthus gen. nov. differs further from T. mcgroutheri by having a considerably longer body, a much longer maxillipedal claw and two (vs. one) armature elements on the terminal process of the maxilla, and from S. cebuana and Umazuracola spp. by having a maxillipedal claw (vs. absent), a well-developed (vs. vestigial) leg 1 and spinulated (vs. coarsely serrated) spines on both rami of legs 2–3 and on the endopod of leg 4.Published as part of Maran, Balu Alagar Venmathi, Moon, Seong Yong, Adday, Thamir Katea & Tang, Danny, 2016, Cepolacanthus kimi, a new genus and species of copepod (Cyclopoida: Taeniacanthidae) parasitic on Bandfish Acanthocepola abbreviata (Valenciennes, 1835) (Actinopterygii: Cepolidae) caught off the Iraqi coast, pp. 249-258 in Zootaxa 4174 (1) on page 251, DOI: 10.11646/zootaxa.4174.1.17, http://zenodo.org/record/26678

Tang Code, Tang Rite, and Other Manuscripts of Tang Dynasty
No full textIn the present paper, the author gives the preliminary reports on three newly found Tang 唐 official documents, pointing out their important value, and offering the all texts for further studies.1. In Tunhuang and Turfan Documents concerning Social and Economic History I. Legal Texts (Tokyo 1978-1980), Professors T. Yamamoto, O. Ikeda, and M. Okano published the joined texts of O. 5098 and O. 8099 from Otani collection. They identified the fragments with the Section on Violence and Robbery of the Tang Code (唐律), and pointed out the article comes from the Yonghui 永徽 or Chuigong 垂拱 Code according to the Zetian 則天 characters used in the Buddhist text on the verso. The author joins another fragment based on an old photograph of the Turfan document preserved in the Lüshun Museum (旅順博物館). The new text contains one different article from the printed text after the Song 宋 dynasty.2. Among the Dunhuang 敦煌 manuscripts in the National Library of China in Beijing, there is a good copy of the Tang Rite (唐礼) in high Tang characters (No. zhou 周 70A). It contains the text corresponding to the Da Tang Kaiyuan li 大唐開元礼, vol. 37: “Huangdi shixiang yu Taimiao 皇帝時享於太廟”. It is the first time to find the book in Dunhuang or Turfan manuscripts.3. In his Dunhuang Turfan Tangdai fazhi wenshu kaoshi 敦煌吐魯番唐代法制文書考釈, Liu Junwen thought the document of zhou 51 should be the Regulations of the Regional Military Organization. But the form of the original document could not conform to the Tang Regulations, so the author refutes his view and thinks that it is an official document relating to the beacon of the military fortress in the area of Dunhuang or Turfan.journal articl
