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.

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.     

African Hepatica XXI. Microlejeunea,Chaetolejeunea and Pleurolejeuna

Abstract

Zoopsis nitida is described as a new species endemic to New Zealand, at present only known from Northland, and appears to be most closely related to Z. setulosa. It differs from other species of the genus in its very reduced leaves which are usually only discernible near the shoot apex.     

Macromitrium maolanense Zeyou Zhang,D.D.Li,Jing Yu & S.L.Guo,a new species from China based on molecular and morphological evidence

Introduction. During a field excursion in Guizhou Province, China, we collected some interesting moss specimens with branch leaves subulate in the upper part, partially and variably bistratose laminae, and a Macromitrium-like epiphytic growth habit on tree trunks. We present morphological and phylogenetic arguments for recognising these plants as a new moss species in the genus Macromitrium Brid. (Orthotrichaceae).

Methods. We compared the morphology of the potential new species with closely related species of Macromitrium, and constructed a phylogenetic tree based on ITS2, trnL and trnG including sampling from 14 other morphologically similar species of Macromitrium.

Key results. The proposed new species belongs to the genus Macromitrium (Orthotrichaceae, Musci). It is closely related to M. gymnostomum Sull. & Lesq. in the phylogenetic tree and according to gametophytic morphological features, represents a hitherto undescribed species.

Conclusions. A new moss species, Macromitrium maolanense Zeyou Zhang, D.D.Li, Jing Yu & S.L.Guo, is described and illustrated. The new species can be distinguished from all congeners by the combination of the following features of the branch leaves: (1) oblong-lanceolate, lanceolate to linear-lanceolate, gradually narrowed to an easily broken subula; (2) rather obscure upper and medial cells, often with blackish stains among cells, densely pluripapillose; (3) variably and partially bistratose laminae in the upper 1/3 portion; (4) basal cells clear, hyaline and smooth, those near costae forming a ‘cancellina region’; and (5) with numerous brownish, clavate gemmae on upper portion. We also discuss the principal distinctive characters separating the new species from its nearest congeners.     

A new sinistral species of the land-snail genus Satsuma (Pulmonata: Camaenidae) from China

ABSTRACT

The species of Satsuma are mostly endemic to East Asia except for one species distributed in Batan Island of the Philippines. More than 99% of the known species of this genus are endemic to the island environment. Only three species are currently known to occur on the mainland. Here we describe a new sinistral Satsuma species from China, Satsuma guandi n. sp. We studied the shell morphology and genital anatomy of the new species and reconstructed the molecular phylogeny of the genus based on partial nucleotide sequences of the mitochondrial gene cytochrome c oxidase subunit I and nuclear markers from the ribosomal RNA cistrons (the internal transcribed spacer and the external transcribed spacer regions). The new species differs from other sinistral Satsuma species by having a strongly angulated shell and an open dark brownish-red umbilicus. The new species also differed from all other sinistral congeners in details of its reproductive anatomy. The molecular analysis supports the validity of the new species within the genus Satsuma.     

<Emphasis Type="Italic">Packera insulae-regalis</Emphasis> (Asteraceae,Senecioneae), a new species endemic to Isle Royale,Michigan, U.S.A.

Packera insulae-regalis (Asteraceae, Senecioneae) is a new species that is only known from one population occurring near the summit of Mount Franklin on Isle Royale, Michigan, U.S.A. It resembles both P. paupercula and P. indecora but is hexaploid, whereas the former has diploid and tetraploid populations and the latter is octoploid around the western Great Lakes. Whereas most species of Packera are self-incompatible (as is P. paupercula) and a few are self-compatible (as is P. indecora), P. insulae-regalis is unique in the genus in being partially self-compatible, as far as is known. Its origin post-glacially by hybridization between these two species is hypothesized.     

A new species report of Caroperla Kohno, 1946 (Plecoptera: Perlidae) from China

A brief taxonomic synopsis of the genus Caroperla Kohno, 1946 is presented and its further generic delimitation is defined along with a new species, C. siveci sp. n. from the Wuyishan Mountain of Fujian, China. It represents the first report of the genus from China and the third species of the genus. The morphological comparison of the new species with the two other known species is given.     

Review of the neotropical endemics Burmeistera, Centropogon, and Siphocampylus (Campanulaceae: Lobelioideae), with description of 18 new species and a new section

Burmeistera, Centropogon, and Siphocampylus together comprise more than 500 species endemic to the Neotropics, Current knowledge of these genera is unsatisfactory, with much diversity yet to be described. Over the past seven years, one out of every 28 specimens received for identification has represented a new species, many characterized by unique or unusual character states. Siphocampylus smilax (Bolivia) is unique in the genus in its parallelodromous leaf venation and extra-floral nectaries. Centropogon dianae (Peru) cannot be accommodated in any recognized infrageneric taxon, and a new section, Centropogon sect. Niveopsis, is proposed for it. The flowers of C. steinii (Ecuador) are the smallest known in the genus, while C. connatilobatus (Venezuela) is the first species to combine arbusculiform pubescence and connate calyx lobes. Burmeistera venezuelensis is only the second species of the genus known to occur in Venezuela and the first to be endemic; similarly, Centropogon wilburii is only the third species of Centropogon known from Mexico and the first to be endemic to that country. Additional novelties are also described.     

Distichophyllum chenii B.C.Ho sp. nov. (Daltoniaceae) from Southeast China

Abstract

Despite the genus Distichophyllum having been revised recently for the Moss Flora of China, upon examination of a wide range of both Chinese and non-Chinese material a distinct new species was found among existing specimens collected from China. The new species, Distichophyllum chenii, is described based on specimens previously misidentified and reported as Distichophyllum cirratum var. cirratum. Published illustrations of D. cirratum var. cirratum based on a misidentified collection of D. collenchymatosum are highlighted to avoid further future taxonomic confusion.     

Revision of the genus Evanos Laporte de Castelnau, 1840, with the description of a second species (Coleoptera: Scarabaeoidea: Rutelidae: Geniatini)

The monotypic genus Evanos (Coleoptera: Rutelidae: Geniatini) is revised and a new species, E. danieleae Grossi, n. sp., is described based on specimens collected from Minas Gerais, Brazil. A lectotype is designated for Evanos villatus. Diagnostic characters and comments about the taxonomic status of the genus are given, as well as a key for both species and a distribution map with the known locality records.     

On Chytridium braun,Diplochytridium N. G., and Canteria N. G. (Chytridiales)

Summary The operculate genus Chytridium Braun is emended and restricted to approximately 25 known species and several incompletely known members which lack an apophysis and develop much like species of Rhizophydium, insofar as the zoosporangium and absorbing or rhizoidal system are concerned, and form endobiotic or intramatrical resting spores. This interpretation corresponds fairly closely to Braun's diagnosis of the type species.A new genus, Diplochytridium, is established to segregate the former Chytridium species with an endobiotic or intramatrical apophysis or prosporangium and resting spores, which may develop sexually or asexually. Some of these species have a well-defined endo-exogenous alternation of growth and development in which the apophysis appears to function as a prosporangium. As interpreted here, Diplochytridium includes approximately 20 of the known species.Another new genus, Canteria, is created for a parasite of Mougeotia which Canter first described as a species of Phlyctidium but later found to develop endobiotic resting spores or zygospores by the fusion of conjugation tubes.     

Dialipsis villahermosae Humala & Selfa n. sp. (Hymenoptera: Ichneumonidae), the second European species of the genus,with biological notes and a key of Palaearctic species

The small genus Dialipsis Förster 1869 (Hymenoptera: Ichneumonidae) includes two known species, of which one is common in Central and Northern Europe. Here we describe the male and female of a new species, Dialipsis villahermosae Humala & Selfa, which was reared from mushrooms collected in Eastern Spain. The host fungus gnat, Mycetophila blanda Winnertz, is a new record for the whole genus, while the rate of parasitism seems very low. Based on environmental data of the collection localities and data available for other two species it is suggested that Dialipsis species occur preferably in cool temperatures habitats. A key of identification of the two known Palaearctic species is provided. D. villahermosae n. sp. differs from D. exilis Förster 1871 in the morphology of the first tergite, referred to the presence of dorsal keels and angle between petiole and postpetiole, and in the convexity of temples.     

A re-evaluation of the Abutilothamnus complex (Malvaceae) I. Two new species and two new genera,Sidasodes and Akrosida

A revision of certain generic boundaries within the tribe Malveae is made. A new genus,Sidasodes, is described with two species, one of which is new,Sidasodes colombiana.Akrosida is segregated as a new genus, based onBastardia macrophylla. The new realignment also recognizesTetrasida as a distinct genus, and describes as newTetrasida serrulata. New combinations includeSidasodes jamesonii (based onSida jamesonii),Akrosida macrophylla (based onBastardia macrophylla), andTetrasida chachapoyensis (based onSida chachapoyensis)     

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.     

VEGETATIVE AND REPRODUCTIVE MORPHOLOGY IN RETICULOCAULIS GEN. NOV. AND NACCARIA HAWAIIANA SP. NOV. (RHODOPHYTA,NACCARIACEAE)1

A secondarily formed reticulum of cells that encloses axial strands and a carposporophyte that is almost entirely converted to sporangia are the diagnostic features of a new genus, Reticulocaulis (Naccariaceae, Nemaliales), with R. mucosissimus as the type species. A new species of Naccaria, N. hawaiiana permits close comparison with the new genus and other previously described species of Naccaria. Until now, no Naccariaceae were known in the Pacific, and these new taxa are part of the sketchily known subtidal marine flora of Hawaii.
