XENOCHIRONOMUS TUBEROSUS SP. NOV. FROM SOUTHERN CHINA,WITH EMENDATION TO THE DIAGNOSIS OF THE GENUS (DIPTERA: CHIRONOMIDAE)*

Abstract Xenochironomus tuberosus sp. nov. from southern China is here described and illustrated as male imagines. The new species is separated from other known species of this genus in having frontal tubercle, unusual stout setae on tergite VI, characteristic chaetotaxy on tergite IX and unique superior volsela. Based on the new species, an emendation to the diagnosis of the genus is given. This paper is the first record of genus Xenochironomus from China.     

The Neotropical Genus Notodiaptomus Kiefer, 1936 (Calanoida: Diaptomidae): Redescription of the Type Species Notodiaptomus deitersi (Poppe, 1891) and Designation of a Neotype

Ribautia williamsi sp. nov., a new dwarf geophilomorph centipede from the Lower Urubamba Region, Peruvian Amazonia, is described and illustrated based on the holotype female. The new species is characterized by having the coxal organs grouped in clusters (three of these in each coxopleuron of the ultimate leg-bearing segment) and ventral pore-fields present along all the body; these two combined traits being shared by five other Neotropical species currently included in the genus Ribautia Brölemann, 1909, i.e. R. centralis (Silvestri, 1907) (from Colombia and Brazil), R. difficilis Pereira, Minelli &; Barbieri, 1995 (from Brazil), R. montana Kraus, 1954 (from Peru), R. peruana (Verhoeff, 1941) (from Peru), and R. titicacae (Turk, 1955) (from Peru). The new taxon is differentiated from the aforementioned species by the low number of leg-bearing segments and small body length; it is included in a key which will enable the identification of all known Neotropical members having coxal organs grouped in clusters. R. williamsi sp. nov. is the 14th species of Ribautia recorded from Peru.

Revision of the cyprinid genus Placocheilus Wu, 1977 in China,with description of a new species from Yunnan

Placocheilus is re-diagnosed on the basis of oromandibular structures compared to those of closely related groups. It is represented in China by three species restricted to Yunnan, namely P. caudofasciatus from the Tengtiaohe River (Nam Na), P. cryptonemus from the Nujiang Rive (upper Salween River basin), and P. robustus, herein described as a new species from the Yuanjiang River (Red River basin). P. robustus n. sp. is differentiated from its congeners in having a stout caudal peduncle (depth 72.4–82.5% of its length) and the medium-sized scaleless midventral region of belly extended slightly beyond halfway from the pectoral- to pelvic-fin origin. It is further distinguished from P. caudofasciatusin having a coarsely crenulated rostral fold with 18–23 indentations on its distal margin and a smaller mental adhesive disc (length 66.7–71.4% of its width and 37.0–43.1% of the head length).     

A new poecilostomatoid copepod (Erebonasteridae) from deep-sea cold seeps at the West Florida Escarpment

A new species of poecilostomatoid copepod, Erebonaster spinulosus (Erebonasteridae), is described on the basis of a single female from a depth of 3 266 m at cold seeps near the base of the West Florida Escarpment in the eastern Gulf of Mexico. Among its distinctive features are: the large body highly ornamented with setules and spinules, the rostrum with small median teeth and lateral setules, the claw of the second maxilla with a prominent knob on the concave margin, the maxilliped ornamented with setules and its claw bearing a digitiform process near the seta, the third segment of the exopod of leg 4 with the formula II,I,4, and the highly ornamented leg 5 having on the free segment a very long seta 9 times the length of the segment.The genus Erebonaster now contains two species, the previously described Erebonaster protentipes found in 2000 m at the Guaymas Basin, Gulf of California, and the new Erebonaster spinulosus.     

Onosma lhokaensis (Boraginaceae), a new species from Xizang,China

A new species of Boraginaceae, Onosma lhokaensis, is described and illustrated from Xizang, China. The new species closely resembles O. waddellii and O. waltonii in having azure corollas, coherent anthers and glabrous filaments, but differs in having particularly bristly indumentum, observably narrow corolla, longer calyxes and anthers, and remarkable nutlets with stipitate cicatrix. An updated key to the species of Onosma known from Xizang is also provided.     

Nanocnide zhejiangensis sp. nov. (Urticaceae: Urticeae) from Zhejiang Province,East China

Nanocnide zhejiangensis X.F. Jin & Y.F. Lu, a new species of Urticaceae from Zhejiang, east China, is described with illustrations. The new species is morphologically similar to Nanocnide japonica in having staminate inflorescence longer than leaves, but differs by having glabrous stems, petioles, peduncles and abaxial leaf surfaces, glabrous perianth lobes of staminate flowers, dorsally glabrous perianth lobes of pistillate flowers, and acuminate or solitary spinose–setaceous at the apex. Analysis based on ITS, atpF–H, atpB–rbcL and trnL–F sequences also demonstrate that Nanocnide japonica is the closest extant relative to the new species.     

On the Genus Trypeticus Marseul (Coleoptera: Histeridae: Trypeticinae) in China

Molecular Phylogeny and Taxonomy of a New Freshwater Hymenostomatid from Northeastern China,with the Establishment of a New Genus Anteglaucoma gen. n. (Protista,Ciliophora, Oligohymenophorea)

The morphology, infraciliature and SSU rDNA sequence of a new freshwater hymenostomatid ciliate, Anteglaucoma harbinensis gen. nov., spec. nov., collected from a farmland pond in Harbin, China, were investigated. The new genus Anteglaucoma is characterized as follows: small to medium‐sized Glaucomidae with oral apparatus in anterior one‐third of cell; paroral membrane composed of almost longitudinally arranged dikinetids; three adoral membranelles nearly equal in length and arranged almost longitudinally in parallel; silverline pattern tetrahymenid. The improved diagnosis of family Glaucomidae Corliss 1971 is provided based on the previous and present work. The type species Anteglaucoma harbinensis spec. nov. is defined by having 32–35 somatic kineties; four or five postoral kineties; membranelle 1 and membranelle 2 having five or six kinetosomal rows, membranelle 3 having three kinetosomal rows; single macronuclear nodule; contractile vacuole on average 15% from posterior body end; locomotion characterized by crawling with a rather hectic jerking motion; freshwater habitat. Phylogenetic analyses show that Anteglaucoma clusters in the family Glaucomidae and groups with the genera Glaucoma. The molecular and morphological data indicate that Glaucomidae is related to the family Bromeliophryidae in the phylogenetic trees.     

TWO ONYCHIURID SPECIES NEW TO CHINA (COLLEMBOLA) *

Abstract Two species of the genus Onychiurus (Collembolai Onychiuridae) new to China are re-described from Yunnan Province by giving new characters: Onychiurus hidayensis from Kunming and O. yodai from Xishuangbanna. The former is characteristic in lacking anal spines and having male ventral organ and the latter is remarkable in having dorsomedian setae on head and Abd. IV-VI.     

Oreonectes guilinensis (Teleostei,Cypriniformes, Nemacheilidae), a new loach species from Guangxi,China

A new loach Oreonectes guilinensis sp. nov. is described from Guangxi Zhuang Autonomous Region, China. It is the second surface-dwelling fish identified in the genus Oreonectes after the type species Oreonectes platycephalus. This new species can be distinguished from other species within the genus by the combination of the following features: a round caudal fin, 13–14 branched rays, an incomplete lateral line with 4–6 pores, a short pelvic fin located some distance from the anus, a scale-covered body, a stout build (body width 14.0%–16.7% of standard length), a posterior chamber of well-developed airbladder and a yellowish-brown body with a lateral dark brown strip. The maximum likelihood phylogenetic analysis based on cytb gene recovered this new species in a well-supported clade with the type species O. platycephalus, sister to the Lefua clade. Morphological comparisons as well as our phylogenetic tree support Oreonectes shuilongensis, Oreonectes daqikongensis, Oreonectes jiarongensis as species of Troglonectes. Based on our results there are 6 valid species in the genus Oreonectes.     

A NEW SPECIES OF ARRHOPALITES FROM MT. CHANGBAI,CHINA (COLLEMBOLA:SMINTHURIDAE)*

Abstract A new species, Arrhopalites chungbaishanensis is described from Mt. Changbai, northeast China. The present species shares some characters with A. octacanthus, but it differs from the latter by the number of vertical thick spines and manubrial dorsal setae, types of dental setae and the absence of tunica on unguis. In comparison with the other congeneric species, the mast striking character of the present species is its special shapes of the C-series setae besetting on sixth abdominal segment.

Oreocharis duyunensis (Gesneriaceae), a new species from Guizhou,China

Oreocharis duyunensis Z.Y. Li, X.G. Xiang et Z.Y. Guo (Gesneriaceae), endemic to Guizhou, China, is described as a new species. The new species is easily distinguished from other Oreocharis species by having a white, stellate ring‐like disc. Morphologically, the species is similar to Oreocharis chienii (Chun) Mich. Möller & A. Weber but differs by its densely white pilose leaves, mixed brown‐pilose, pubescent and glandular‐pubescent peduncle and pedicle, white stellate ring‐like disc, and linear‐lanceolate capsule. Based on phylogenetic reconstruction and interspecific genetic distances of nuclear ITS and chloroplast trnL‐F regions, O. duyunensis is a new species with uncertain phylogenetic position.
