Sucrea (Poaceae: Bambusoideae), a new genus from Brazil

Sucrea, a new genus of herbaceous bambusoid grasses is based on the newly described species,S. monophylla. Also belonging to this genus is another new species,S. maculata, and the taxon originally namedOlyra sampaiana. The new genus is contrasted in a key with others of its tribe Olyreae, and a key is given to its three species.     

New species and nomenclature in Prospodium (Uropyxidaceae, Pucciniales) and the new anamorphic genus Canasta in the neotropics

Ten new teleomorphic species, two status novus taxa and two new combinations in the genus Prospodium are established. The following anamorphs, all closely related to the genus Prospodium, also are proposed: the genus Canasta, its two new species and a new combination, three new combinations for the genus Uredo.     

A review of the Banchus-group of ichneumon-flies, with a revision of the Australian genus Philogalleria (Hymenoptera: Ichneumonidae)

ABSTRACT. The composition and relationships of the Banchus genus-group are discussed. A key to the genera is provided and for each genus a diagnosis and notes are given. A new genus and species are described. The genus Philogalleria Cameron is revised: six species (five of them new) are recognized, described and keyed. Rhynchobanchus is newly recorded from Britain and a key is given to its European species.     

A new genus and species of adapid primate from the middle Eocene of Alsace, and a new genus for 'Adapis' ruetimeyeri Stehlin, 1912

A new primate genus and species, represented by isolated teeth, is described from the middle Eocene Alsatian site of Bouxwiller. This new form is closely related to Egerkingen 'Adapis' ruetimeyeri, for which a new genus is proposed because of the important distinctions from type Adapis present in its dentition. Nonetheless, both new genera are closely related to Adapis and Leptadapis.     

Singchia and Gunnaria, two new genera of Orchidaceae

Singchia Z. J. Liu ＆ L. J. Chen, a new orchid genus, is established based on the new species S. malipoensis Z. J. Liu ＆ L. J. Chen found in southeast Yunnan, China. The new genus is related to Pteroceras, from which it differs by having a lip with its basal margins immovably adnate to the lower part of the pendent column foot, a thin-walled spur, and very unequally and deeply split pollinia, each with a distinct caudicle. In addition to a discussion on Ascocentrum pusillum, a species of questionable placement, another new genus, namely Gunnaria S. C. Chen ex Z. J. Liu ＆ L. J. Chen, is set up and a new combination, namely G. pusilla （Aver.） Z. J. Liu ＆ L. J. Chen, is made. The new genus Gunnaria differs from its allyAscocentrum by having a cross-shaped pollinarium, sulcate or split pollinia, each with a distinct caudicle attached to a common linear stipe much longer than either pollinia or viscidium, and strongly incurved side lobes of the lip.

A NEW SPECIES OF MOERITHERIUM (PROBOSCIDEA, MAMMALIA) FROM THE EOCENE OF ALGERIA: NEW PERSPECTIVES ON THE ANCESTRAL MORPHOTYPE OF THE GENUS

Abstract:  A new species of Moeritherium (Proboscidea, Mammalia), M. chehbeurameuri sp. nov., is described from remains discovered in the early late Eocene locality of Bir El Ater, Algeria. Although mainly represented by isolated teeth, it shows distinct synapomorphies which justify its attribution to the genus Moeritherium , together with exclusive features that led to the creation of the new species. The main characteristic of this new taxon is the almost complete lophodonty shown by its molars, while Moeritherium is commonly regarded as a bunolophodont to bunodont taxon. In addition to this lophodonty, this new taxon shows anatomical features as yet unknown for the genus, but often met within lophodont early proboscidean taxa such as Phosphatherium escuilliei and Numidotherium koholense . Although a revision of the whole genus Moeritherium is outside the scope of this paper, the main controversies and discussion about the definition of species within the genus Moeritherium are discussed. The surprising lophodonty of M. chehbeurameuri , together with its small size, its early late Eocene age and the weak molarization of its P₃ support the hypothesis of a lophodont hypothetical ancestor for moeritheres, and therefore strengthen the growing hypothesis of a lophodont dental ancestral morphotype for proboscideans.     

中国须鳗属鱼类一新种(鱼纲,鳗鲡目,蛇鳗科)

在编写中国动物志(鳗鲡目)过程中,检测了保存于中国科学院动物研究所和上海水产大学历年采集的蛇鳗科鱼类标本,发现其中有1新种,定名为元鼎须鳗Cirrhimu-raena yuanding sp．nov．,以纪念中国第一代鱼类学家朱元鼎教授对中国鱼类学研究的贡献。该新种由于其上颌下表面中央所具有的凹槽和头背部后1/3处的背鳍起点等特征,是已知的其他9种须鳗属鱼类中所特有的特征,可明显区别于本属的已知种类。     

Broadening the definition of the genus Thalassaphorura Bagnall, 1949 (Collembola,Onychiuridae) with a new aberrant species from China

A new species belonging to the tribe Thalassaphorurini, Thalassaphorura problematica sp. n., is described from Northeast China. The new species is closest to the large genus Thalassaphorura by its simple vesicles in PAO and its furcal rudiment, but it does not fit the definition of the genus by the absence of chaeta d0 on head, the number of chaetae in the distal whorl of tibiotarsi and the labium type. We discuss the relative weakness of these last characters at generic level, which lead us to assign the new species to Thalassaphorura instead of erecting a new genus. The diagnosis of Thalassaphorura is broadened accordingly.     

A redescription of Periclimenaeus fimbriatus Borradaile, 1915, with the designation of a new genus (Crustacea: Decapoda: Palaemonidae)

Specimens of Periclimenaeus fimbriatus Borradaile, 1915, a palaemonid shrimp reported from only three localities in the Western Indian Ocean, are described and illustrated. The species is removed from the genus Periclimenaeus Borradaile and a new genus Paraclimenaeus is designated for its accommodation. The characteristic features of the genus and its relationships are discussed. The palaemonid shrimp genera associated with sponge hosts are reviewed and a key provided for their identification

From the inside out: Discovery of a new genus of threadsnakes based on anatomical and molecular data,with discussion of the leptotyphlopid hemipenial morphology

The systematics of Leptotyphlopidae is historically controversial mostly due to their conserved external morphology in comparison with other snakes. However, recent studies have stressed that anatomical data might be informative for clarifying the leptotyphlopid taxonomy and evolution. We erect a new genus to accommodate Leptotyphlops collaris based on evidence from osteology, hemipenial morphology, and molecular data. We also provide expanded data regarding the intraspecific variation based on additional specimens collected in field trips and literature data, performing detailed comparisons among the new genus and all other New World leptotyphlopids. The new genus is distinguished from other leptotyphlopids by its unique hemipenial morphology and its exclusive combination of osteological and external morphology characters, with molecular data also supporting the new generic arrangement. We also provide a comprehensive discussion of the hemipenial morphology for the subfamily Epictinae based on literature and novel data gathered herein.     

Mariapanteles (Hymenoptera, Braconidae), a new genus of Neotropical microgastrine parasitoid wasp discovered through biodiversity inventory

A new genus of microgastrine parasitoid wasps, Mariapanteles Whitfield & Fernández-Triana, gen. n., is described from rain forests of the Neotropics. The new genus is related to the common and speciose genus Pseudapanteles, but can be distinguished from the latter by having a complete transverse carina on the propodeum which forks around the spiracles. A molecular analysis based on data from COI from specimens of the proposed new genus plus possibly related genera confirms its generic distinctness. A key to two known species, Mariapanteles felipei Whitfield, sp. n. (Costa Rica) and Mariapanteles dapkeyae Fernández-Triana, sp. n. (Brazil) is provided. Evidence from collections suggests that there are other undescribed Neotropical congenerics. Specimens of Mariapanteles were likely confused in the past with the genus Beyarslania (referred to as Xenogaster until recently) but present information suggests that Beyarslania is restricted to the Afrotropical region while the Neotropical species clearly belong to a different genus, which we propose as new.     

A new genus of soft coral of the family Alcyoniidae (Cnidaria, Octocorallia) with re-description of a new combination and description of a new species

A new genus, Aldersladum (family Alcyoniidae), is established to accommodate a previously described species, Efflatounaria sodwanae Benayahu, 1993 (family Xeniidae) from Sodwana Bay, South Africa that was wrongly assigned to the latter genus. This species is redescribed and a second new species, Aldersladum jengi from Penghu Is., Taiwan, is described. The diagnostic features of the new genus include the presence of only figure-eight shaped platelets in all parts of the colony, thus differentiating it from all known genera of the Alcyoniidae. Based on examination of additional material from other localities, the zoogeographical distribution of the genus is confirmed to include the coral reefs of South Africa, Kenya, Gulf of Oman, Taiwan and Japan. Phylogenetic analyses of two mitochondrial genes strongly support its placement in the family Alcyoniidae.
