Pasture Legume

Stylosanthes macrocephala was described as a new species in 1977 and has become an economically important pasture legume. It has recently been claimed to be conspecific with S. capitata, also an economically important species. This paper refutes this synonymization and summarizes morphological descriptions as well as genetic studies and cytological evidence indicating that diploid S. macrocephala should be considered a separate species, even being a likely progenitor of tetraploid S. capitata. Early confusion with S. bracteata is also discussed.

A New Species

The Atlantic Forest of Brazil includes one of the highest species diversity and endemism in the planet, representing a priority for biodiversity conservation. A new species of Anemopaegma from the Atlantic Forest of Brazil is here described, illustrated and compared to its closest relatives. Anemopaegma nebulosum Firetti-Leggieri & L.G. Lohmann has been traditionally treated as a morph of Anemopaegma prostratum; however, additional morphological and anatomical studies indicated that A. nebulosum differs significantly from A. prostratum and is best treated as a separate species. More specifically, A. nebulosum is characterized by elliptic and coriaceous leaflets (vs. ovate to orbicular and membranaceous in A. prostratum), smaller leaflet blades (3.6–5.5 x 2.0–3.0 cm vs. 6.7–13.0 x 4.2–8.4 cm in A. prostratum), orbicular prophylls of the axillary buds (vs. no prophylls in A. prostratum), solitary flowers (vs. multi-flowered axillary racemes in A. prostratum) and a gibbous corolla (vs. infundibuliform corollas in A. prostratum). In addition, A. nebulosum differs from A. prostratum anatomically in having thicker leaflet blades composed of two to four layers of palisade parenchyma (vs. one to three layers in A. prostratum), and seven to eight layers in the spongy parenchyma (vs. six to eight layers in A. prostratum). A key for the identification of all species of Anemopaegma from the Atlantic Forest of Brazil is presented.

A New Species

Centaurea crocata Franco (1984: 474, 572) is the name currently used for a species of Asteraceae that is endemic to a small area in the southwest of Portugal, extending from Monchique (Algarve) to Cercal (Baixo Alentejo). The plant was first collected by Friedrich Welwitsch in 1847, in Monchique, during his residence (1847–1848) in the province of Algarve (Trimen 1873: 3). The following year he collected it again but further north, in Baixo Alentejo. Welwitsch regarded it as a new species and informally named it ‘Centaurea crocea’, as is apparent from the name written on his specimens of this species that are held in LISU (Garcia Jacas & Susanna 1991). However, he never published this name. Later authors working on the flora of Portugal, such as Sampaio (1909: 60, 1947: 597) and Coutinho (1913: 657, 1939: 776) misidentified Welwitsch’s and other collectors’ material as C. prolongoi Boissier ex Candolle (1838: 303, originally published as ‘prolongi’, corrected to ‘prolongoi’ as it commemorates the Spanish botanist Pablo Prolongo y Garcia). It was only much later that Franco (1984), in the second volume of his Flora of Portugal, concurred with Welwitsch’s view that the material belonged to a separate species and described it as C. crocata, using an epithet similar to that of Welwitsch’s unpublished name. Both epithets ‘crocata’ and ‘crocea’ originate from Latin and mean saffron-coloured. Saffron is a product of a species of the genus Crocus Linnaeus (1753: 36), a name with the same origin.

Based on morphological and molecular phylogenetic studies, Semiaquilegia danxiashanensis, a new species from Danxia Shan in northern Guangdong, southern China, is described and illustrated. This species is easily distinguishable from each of other three known species in the genus by characters of the flowers and fruits. In addition, molecular phylogenetic analyses of both the nuclear ITS and the plastid trnL-F region strongly supported S. danxiashanensis as a separate species from other species of Semiaquilegia. We provide a detailed morphological and habitat description, distribution, as well as colour photographs and illustrations of the new species.

A New Species

The history of the genus Eupithecia Curtis is reviewed, and a preliminary redescription of the genus is proposed on the basis of the Palaearctic, Nearctic and Oriental fauna. Several Asian species previously placed in Eupithecia  have been found to be anomalous. These are examined and some are placed in related genera, two of them new (Pareupithecia and Girida). A further group (the ‘subrubescens’ group) is retained within Eupithecia as a separate species group. The genus Eva Vojnits is redescribed. A new species is described in the genus Mesoptila Meyrick. Descriptions are given of all genera involved, and full lists of taxa included within them, with the exception of Eupithecia itself. Selected adults and genitalia are illustrated. Taxonomic changes proposed in this paper include: new genera Pareupithecia, Girida; new species  Mesoptila murcida; new synonymies, Emmesocoma Warren, 1907 of Mesoptila Meyrick, 1891 and Horisme sternecki Prout, 1938 of Chloroclystis chingana Wehrli, 1926; new combinations Mesoptila melanolopha Swinhoe, 1895, Mesoptila unitaeniata Warren, 1906, Mesoptila deviridata Warren, 1907, Mesoptila excita Prout, 1958, Mesoptila festiva Prout, 1916, Eupithecia eurytera Prout, 1938, Eupithecia chingana Wehrli, 1926, Pareupithecia spadix Inoue, 1955, Girida rigida Swinhoe, 1892, Girida sporadica Prout, 1932; reinstated taxon Eupithecia brevifasciaria Leech, 1897; and status change  Girida sporadica Prout, 1932.

Coreoleuciscus splendidus was first reported as a monotypic species. Recent morphological and genetic studies have revealed that the species is represented by two disjunct and distinct lineages. The two lineages of C. splendidus include populations inhabiting the Han and Geum rivers in the East Korea Subdistrict and populations inhabiting the Seomjin and Nakdong rivers in the South Korea Subdistrict. In this study, significant differences were found between these two independent lineages through a high degree of genetic divergence in the mitochondrial cytochrome c oxidase subunit I gene as well as conspicuous morphological differences in body coloration and shapes of black stripes on dorsal, anal and caudal fin rays. These morphological and genetic differences provide supporting evidence that the populations in the South Korea Subdistrict represent a new species, Coreoleuciscus aeruginos.

A New Species

Amongst the unnamed Alcyonaria in the collection of the Royal Scottish Museum, Edinburgh, is a beautiful colony belonging to the genus Cactogorgia, which Mr Eagle Clarke has kindly handed me for identification and description.In 1907 (Trans. Roy. Soc. Edin.) I established the genus Cactogorgia for several small colonies from the Indian Ocean, and referred these to three separate species, viz. celosioides, alciformis, and expansa. Thomson and M'Kinnon, in Trans. Linn. Soc. (Zool.), 1909, have described another species from the Seychelles under the name of Cactogorgia lampas, and the present colony must also be referred to a new species. This we propose to name Cactogorgia agariciformis, n. sp., on account of its very definite mushroom-shape.

Scientific Name

The leafhopper genus Amrasca Ghauri from China is reviewed. Six species are included, of which three are reported for the first time from China. A new species, A. (Amrasca) complana Qin, Wang & Xu, sp. nov. is described based on specimens from south China. A complete checklist of the genus and an identification key to species in the Chinese fauna are provided. Jacobiasca curvata (Ahmed & Samad) comb. nov. is removed from Amrasca and A. (A.) singularis Einyu & Ahmed is treated as a species incertae sedis. Habitus photos of all Chinese Amrasca species and illustrations of male genitalia of the new species are also given. The male holotype specimen of Chlorita bimaculata Matsumura is here designated as the neotype of Empoasca biguttula Ishida to fix the identity of this economically important species and Sundapteryx Dworakowska is reinstated from synonymy as a subgenus of Amrasca. Thus, the correct scientific name of the Indian cotton leafhopper is Amrasca (Sundapteryx) biguttula (Ishida).

Peponium elgonense, a new species of Cucurbitaceae from Mount Elgon in Kenya, is described and illustrated here with photographs. This species is similar to P. cienkowskii and P. vogelii, but differs by being monoecious and having a longer ovary. A molecular phylogenetic analysis of Peponium based on ITS and five plastid markers (trnL–F, rpl20–rps12, matK, rbcL, and trnL intron) of four species of Peponium further shows that P. elgonense individuals cluster together supporting the argument to regard it as a separate species.

A New Species

A new species of vestimentiferan tubeworm belonging to the genus Escarpia is described from cold seeps off the western coast of Africa. The description is based on two collections (one of 180 animals, the other of 30 animals) using both morphological and molecular techniques. Morphologically, the African tubeworms are very similar to Escarpia laminata Jones, 1985 but differ from all other escarpids by the lack of branchial pinnules, a unique feature among vestimentiferans. Molecular evidence from sequences of the cytochrome-c oxidase subunit I gene places the species in the escarpid clade, closely related to E. laminata and Escarpia spicata Jones, 1985, but fails to discriminate among the three species. Four morphotypes are identified in the African species, corresponding to the four permutations of the following characters: presence or absence of an axial rod on the obturaculum and presence or absence of a split on the posterior ventral margin of the vestimentum. However, molecular data could not distinguish them as separate species. We suggest that the lack of an axial rod reflects predation. Biometrical data indicate a discontinuous recruitment period, as is known for other vestimentiferan species. Sex ratios are balanced, but females tend to be larger than males. We hypothesize that the males grow more slowly or die younger than the females.
