Abstract

A new genus, Picobryum (Pottiaceae, Bryophyta), including one new species, Picobryum atomicum, is described from the western Cape Province of South Africa. The new taxon is somewhat similar to Syntrichia gametophytically but differs in the trait combination: stem very short, central strand absent; leaves strongly reflexed to squarrose when moist, usually folded longitudinally on one side, bases sheathing, margins plane throughout, irregularly and weakly bordered in 1(–2) rows with somewhat thick-walled, less papillose cells; papillae large, simple to bifid, 1–2 per lumen; paroicous; seta essentially absent; capsule cleistocarpic, globose, and short-apiculate; calyptra mitrate. Locality data for the type of Acaulonopsis fynbosensis R.H.Zander &; Hedd. are corrected in an erratum.  相似文献

Abstract

Indopottia zanderi, a new genus and species of the Pottiaceae, is described from the Silent Valley National Park in the Western Ghats in Peninsular India. The distinctive features of Indopottia are the leaf cells being weakly convex on both surfaces, costal stereid-band semicircular in cross-section, guide cells rounded-ovate or semicircular, seta short and operculum very long. The affinities of the allied genera, Ganguleea, Tortula and Weisiopsis, are discussed. The new genus Indopottia may be placed in the tribe Hyophileae.  相似文献

Summary

In this publication, a subdivision of the genus Annenica O. Boettger, 1877 sensu Auct. is proposed. One result of our study is the recognition of the genus Sprattia O. Boettger, 1883 for most of the South Anatolian species of the former genus Armenica. The genus Astrogena Szekeres, 1970, which was synonymised by H. NORDSIECK (1975: 98) with Armenica is redefined and used as a subgenus of Armenica for some species. Extensive recent collections contain new species and subspecies of this genus, which are described here.  相似文献

A new genus of Aeshnidae, Huncoaeshna n. gen., based on Huncoaeshna corrugata n. gen., n. sp., is erected from Laguna del Hunco (Ypresian) in Patagonia Argentina. The specimen presents a special kind of preservation with the middle part of the wing wrinkled. The presence of only two fossil specimens of Aeshnidae in South America is surely due to the lack of paleontomologists and collections of fossil insects in the subcontinent.  相似文献

The 22 species of the genus Micrambe Thomson known from South Africa are analyzed and revised. Micrambe danielssoni sp. nov is described. Following a detailed study of the type material in different entomological collections, the status of two taxa is revised and two new synonymies are proposed: Micrambe kolbei Grouvelle 1908, syn. nov. for Micrambe minuta Grouvelle 1908, and Micrambe similis Bruce 1957, syn. nov. for Micrambe peringueyi Grouvelle 1908. A lectotypus is designated for one taxon: Micrambe capensis (Redtenbacher 1867). A key to all the species occurring in South Africa is presented.  相似文献

ABSTRACT

Euathlus

Ausserer, 1875 is a South American genus of spiders of the family Theraphosidae known from Chile and Argentina. Three new species from Argentina: Euathlus mauryi sp. n. (from San Juan province), Euathlus grismadoi sp. n. (from La Rioja province), and Euathlus pampa sp. n. (from Salta province) are described here. New records of the previous species Euathlus diamante and Euathlus tenebrarum are contributed. The distribution of these new species expands the geographical distribution of the genus along the Andean hills, with Salta province as the northernmost record of the genus. A key is provided for identification of Euathlus species as well as a map with all the records in Argentina.  相似文献

Introduction. Over the last years we have been engaged in studies of the South American Pottiaceae. Among the bryophyte specimens collected by us in central and northern Peru, some samples of a puzzling Pottiaceae were found. In this paper, we present our arguments for recognising these plants as a new species and its inclusion in Erythrophyllopsis Broth.

Key Results. It differs most saliently from other species of Erythrophyllopsis by the combination of its oblong-ovate to ovate-lanceolate leaves, with usually fragile apex, leaf margins papillose-crenulate from apex to lower third, sometimes erose or crenate, lamina unistratose, occasionally bistratose in patches, costa broad, usually ending below the apex, without dorsal stereids near the apex where they are replaced by cells similar to those of the lamina, and short and straight peristome teeth.

Conclusions. A new moss species, Erythrophyllopsis perlaticosta M.J.Cano & J.A.Jiménez, is described and illustrated from the Andean highlands in central and northern Peru. A revised identification key for the species of Erythrophyllopsis is also provided. This species grows in crevices or fissures of calcareous rocks or banks between 3050 and 4700?m. The principal distinctive characters that separate it from the nearest species of Erythrophyllopsis and related genera such as Bryoerythrophyllum P.C.Chen and Mironia R.H.Zander are discussed.  相似文献

The catshark genus Holohalaelurus Fowler is currently represented by five species distributed off the southern and eastern parts of the African coast. Very few parasitological records exist for any of these five species, representing a significant knowledge gap. We report the first monogenean species from the bathydemersal species Holohalaelurus regani (Gilchrist): a new species of Microbothriidae Price, 1936, Leptomicrobothrium holohalaelure n. sp. from the dorsal skin surface, and a new species of Hexabothriidae Price, 1942 representing a new genus, Scyliorhinocotyle narvaezae n. gen., n. sp., from the gill lamellae. Both monogenean records represent the first for any member of the catshark genus Holohalaelurus. Previously we focused on the identification of monogenean taxa of emerging veterinary importance for public aquaria. We now begin a focused effort to document a generally unexplored monogenean biodiversity from diverse marine habitats off South Africa.

Bursera inversa is the first new species of the genus to be described from South America in 90 years. The ecology of this species is remarkable because it is a large (to 25 m × 40 cm or greater) canopy tree of primary moist to wet lowland forest. It is easily distinguished from its congeners by its large, obovoid fruits and bony pyrene. A key to the South American species ofBursera is provided.  相似文献

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)  相似文献

Abstract

Three new species of genus Thrips are described—austellus, coprosmae, and phormiicola—which are closely related to the common New Zealand species T. obscuratus (Crawford). The systematic and zoogeographic significance of this endemic species-group is discussed. Physemothrips hadrus n.sp. is described from the South Island; the only other member of this genus is from Macquarie Island. Anaphothrips zelandicus n.sp. is described from the South Island and the Chatham and Antipodes islands, A. woodi Pitkin is recorded from New Zealand, and the relationships of these two species to the Australian fauna are discussed.  相似文献

香溪叶肢介亚科(Xiangxiellinae)以壳瓣胎壳较大、壳上具有一条或两条短脊为特征,包括两个属:原单脊叶肢介属(ProtomonocarinaTasch,1962)和香溪叶肢介属(XiangxiellaShen,1976)。该亚科化石广布于世界各地,最早出现于我国晚石炭世,三叠纪末消失。本文建立的新属叉脊叶肢介(Dicerestheriagen.nov.),以胎壳上具有两条呈“人”字形向前后分叉的、粗壮的短脊为特征,与香溪叶肢介的构造特征最为接近。推测新属壳瓣胎壳脊的形成与闭壳肌附着引起的壳瓣变异或与生态环境变化有关。化石产于江西抚州崇礼县礼陂煤矿,上三叠统安源组徐坊段。湘赣一带安源组为一套含煤地层,属于滨海、近海、沼泽沉积区,产半咸水类型的双壳类,时代认为卡尼及早诺利期。植物化石Ptiozamites–Anthrophyopsis组合是诺利期的代表,适宜于热带、亚热带气候,滨海环境生长的群落。因此推测新属是一个生活在炎热、潮湿的热带-亚热带气候近海沼泽环境的类型。  相似文献

Abstract

Ten taxa of Pottiaceae considered endemic to North Africa have been studied and typified. Nine are newly synonymized with other well-known taxa. A new combination is proposed: Weissia condensa var. armata (Thér. & Trab.) M.J.Cano, Ros & J.Guerra. The distribution of Acaulon triquetrum var. desertorum (Besch.) Jelenc and Weissia condensa var. armata are respectively extended to Europe and the African continent. Barbula muralis var. obovata Schimp. is a misprint in the publication of the taxon. Two nomina nuda, Tortula cuneifolia var. caulescens Jelenc and Tortula cuneifolia var. pilifera Jelenc have no taxonomic value.  相似文献

Three sphaerodorid species new to science are described from a manganese nodule area in abyssal depths of around 4150 m in the Peru Basin in the eastern South Pacific. Sphaerodoridium campanulata sp. n. is isolated within the genus, having, apart from spherical macrotubercles, additional dorsal stalked bell-shaped papillae, not previously described. Sphaerodoropsis discolis sp. n. is a species with four rows of dorsal macrotubercles and two pairs of lateral antennae. Sphaerodoropsis translucida sp. n. has six to seven rows of dorsal macrotubercles arrayed in two transverse rows per segment and two pairs of lateral antennae. A brief discussion points to the close relationship between Clavodorum and Sphaerodoridium, and to the present state of Sphaerodoropsis, being inhomogeneous in the characters of the arrangement of the dorsal macrotubercles and the numbers of the lateral antennae. An overview on the latter genus, with an attempt to subdivide it, is given.  相似文献
