A revision of the Chinese Catops Paykull 1798 of the Catops fuscus species group (Coleoptera: Leiodidae: Cholevinae)

Five species of the Catops fuscus species group are reported from China. Three species are newly described: C. hlisnikovskyi n. sp. from the Beijing municipality and Jiangsu province, C. schuelkei n. sp. from Sichuan and Yunnan provinces, and C. smetanai n. sp. from Sichuan and Yunnan provinces. Female of C. sasajii Nishikawa 2007 is described and the species is reported from Hubei, Sichuan and Yunnan provinces for the first time. Catops nigricans (Spence 1813) is reported for the first time from China (Xinjiang Uygur autonomous region). Important morphological characters are illustrated and the distribution of all species in China is mapped. Preliminar phylogenetic analysis separates (C. hlisnikovskyi n. sp.+C. fuscus fuscus Panzer 1794) as a sister clade to C. nigricans+(C. sasajii+(C. schuelkei n. sp.+C. smetanai n. sp.)), with C. paramericanus Peck & Cook 2002 as outgroup.     

Impatiens bomiensis (Balsaminaceae), a new species from Xizang,China

Impatiens bomiensis, a new species of Balsaminaceae from Bomi County, Xizang, China, is described and illustrated. This new species is similar to Impatiens fragicolor based on morphological characters and molecular data, but differs in the shape of the lower sepal, the dorsal petal and the number of globose glands at petiole base.     

The genus Gottschelia Grolle (Jungermanniopsida,Lophoziaceae) in China,with a description of G. grollei,sp. nov.

Abstract

The genus Gottschelia Grolle is reported as new to mainland China, from Yunnan Province. Previously G. schizopleura (Spruce) Grolle was the only known Chinese species, reported from Taiwan. However, two further species have recently been found in the Gaoligong Shan range, Yunnan Province, G. patoniae Grolle, Schill & D.G. Long, previously known from the East Himalaya of Nepal and India (Sikkim) and G. grollei D.G. Long & Váňa, described here as a new species endemic to China, the fourth known species in the genus. The differences between the three Chinese species are enumerated with notes on distribution and ecology.     

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

This paper describes two new species, Trypeticus fissirostrum n. sp. from Hainan and Trypeticus yunnanensis n. sp. from Yunnan Provinces, China. Three Trypeticus species having been recorded in the territory of China before this study, their total number in this country has now increased to five. A key to the Chinese species is compiled and given in the text. The type specimens are deposited in Institute of Zoology, Chinese Academy of Sciences.

Descriptions of the first semi-aphenopsian troglobiotic Patrobini and of a new anophthalmic cave-dwelling Trechini from central Sichuan,China (Coleoptera: Caraboidea)

Summary

The first known troglobiotic species belonging to the ground beetle tribe Patrobini is reported from a limestone cave called Lianhua Dong in Pengzhou, a suburb county-level city in northern Chengdu, Sichuan Province, China. Troglopatrobus zhouchaoi n. gen., n. sp., is an eyeless and large-sized patrobine beetle with extremely elongated body (esp. head and elytra) and appendages. Duvalioblemus (Shublemus) liyuani n. subgen., n. sp., a minute anophthalmic trechine species, is also discovered from the same cave. It is the first cave-dwelling species belonging to this genus already known as endogean from Sichuan and Yunnan provinces.     

<Emphasis Type="Italic">Lophodermium</Emphasis> on needles of conifers from Yunnan Province,China

Twelve Lophodermium species on needles of conifers are known in Yunnan, the eastern Himalayas in China. Recently, additional specimens were collected and identified. Two new species, Lophodermium dilutum on Pinus armandii and Lophodermium tsugae on Tsuga dumosa, were described and illustrated, and six species, L. autumnale, L. confluens, L. himalayense, L. kumaunicum, L. laricinum, and L. nitens, were recorded for the first time for Yunnan. A key to the Lophodermium species on needles of conifers for Yunnan is provided.     

Impatiens liboensis sp. nov. (Balsaminaceae) from Guizhou,China

Impatiens liboensis K. M. Liu & R. P. Kuang, a new species collected from Xiaoqikong Scenic Area in southern Guizhou, China, is described and illustrated, including its seed and pollen micro‐morphology. Impatiens liboensis is similar to I. chishuiensis Y. X. Xiong and I. tubulosa Hemsl., but differs by having obviously irregular underground tubers, white or pink–white flowers, lower sepal with a 1.2–1.5 cm long spur, obovate dorsal petal, and obovate‐oblong or obliquely obovate lower lobes of the lateral petals with retuse apex.     

Impatiens quadriloba sp. nov. (Balsaminaceae) from Sichuan,China

Impatiens quadriloba K. M. Liu et Y. L. Xiang sp. nov. collected from the Siguniang Mountains Nature Reserve in northwestern Sichuan, China, is described and illustrated. The seed‐coat and pollen morphology of the new species are described and diagnostic morphological characters that distinguish the new species from the related I. falcifer Hook. f. are discussed.     

Pliocene white pine (Pinus subgenus Strobus) needles from western Yunnan,southwestern China

Abstract

The fossil records of Pinus L. are abundant since the Late Cretaceous, especially for the subgenus Pinus L. (the hard pines). However, those of the subgenus Strobus (D. Don) Lemmon (the white or soft pines) are not well documented. In this study, we describe a new species of white pines, Pinus plioarmandii sp. nov., from the Pliocene of western Yunnan, southwestern China. This species mostly resembles extant P. armandii Franch. in gross morphology and cuticular structure of needles. Molecular dating showed that the Asian white pines split into two lineages around the Late Miocene, and the Pinus armandii clade diverged at the Early Pliocene. The present fossil occurrence indicates that Pinus armandii might originate in southwest China and probably in the western Yunnan. The glacial events during the Pleistocene might be the major factors for the retreat of the white pines from western Yunnan, and the rapid uplift of the Yunnan Plateau and deep incision of the river valleys since the Pliocene had posed a significant geographic barrier for their reconnection in the subsequent warm climate condition.

Two new species of Ulota (Orthotrichaceae,Bryopsida) with multicellular spores,from the Hengduan Mountains,Southwestern China

Abstract

Two new species, Ulota yunnanensis and Ulota gigantospora, are described from Yunnan and Sichuan Provinces, China. Both have multicellular spores, a relatively uncommon character in the genus. Differences between the species include growth form and habit, leaf areolation, capsule shape, peristome structure and ornamentation, operculum shape and colour, as well as vaginula and calyptra hairiness. These characters and those discriminating the new species from other ones with similar spore type are discussed and illustrated.     

A new species and a new combination of <Emphasis Type="Italic">Allium</Emphasis> sect. <Emphasis Type="Italic">Rhizirideum</Emphasis> (Alliaceae) from northeastern China and Korea

A new species, Allium pseudosenescens, belonging to sect. Rhizirideum (Alliaceae), is described from northeastern China. It is easily distinguished from A. senescens by the slender pedicels, pale pink perianths, narrower tepals and ovaries, yellowish anthers, and sometimes toothed subulate filaments. Also, A. senescens var. minus in sect. Rhizirideum is raised to the rank of species, as A. minus. This Korean endemic taxon is shown to be a biologically distinct species based on morphological and cytological characters. Taxonomic keys for the species of Allium sect. Rhizirideum in northeastern China and Korea are provided.

Yunotrechus diannanensis n. gen., n. sp., the first troglobitic trechine (Coleoptera: Carabidae) from a tropical area of China

In the present paper Yunotrechus diannanensis n. gen., n. sp. is described and illustrated from two limestone caves which are close to each other in Wenshan and Maguan counties of southern Yunnan Province, southwestern China. Yunotrechus is an anophthalmoid, not directly related to any hypogean trechine genera hitherto known in Yunnan or in southeastern Asian countries because all of them are aphaenopsoids, with elongated prothorax and tumid propleura. The phylogenetic position of Yunotrechus within Trechinae in China or southeastern Asia remains unclear, although it may be related to Superbotrechus Deuve & Tian 2009, which was recorded from western Hubei Province, central China, and Sichuanotrechus Deuve 2006, which was recorded from northern Sichuan Province, southwestern China. Y. diannanensis n. sp. is the first troglobitic trechine beetle discovered in a tropical area of China.
