The tanaid genus Hexapleomera has long been considered to be monotypic, comprising a cosmopolitan species predom-inantly commensal on turtles, or, more rarely, manatees. Recent discovery of material of a distinct species ofHexapleomera living on the hulls of yachts in south-west England encouraged re-assessment of the literature on this taxon,and re-examination of free-living benthic material from the eastern Mediterranean. As a result, five species are recognizedwithin the genus Hexapleomera; two new species are described, Pancoloides moverlyi is moved to Hexapleomera, and H. robusta sensu Edgar is elevated to specific rank and re-named.

Three New Species

Abstract Three new species are described from sheltered intertidal sediments of Papanui Inlet, southern New Zealand. Microlaimus falciferus n. sp. is characterised by a cuticle with two lateral alae, the presence of pores between the cephalic setae, a strongly sclerotised and non-compartmentalised mouth cavity and scythe-shaped spicules with two sub-lateral pre-cloacal setae. This is the first species of the family Microlaimidae described as having lateral differentiation of the cuticle. Microlaimus falciferus n. sp. can also be differentiated from other Microlaimus species by the presence of two types of porids, i.e., pores and short hollow setae, as all other species of the genus possess only one type of porid (when present). Aponema subtile n. sp. is characterised by its slender form, relatively long tail, presence of longitudinal bars and lateral grooves on the cuticle and groups of short setae in the pre- and post-cloacal regions. It is similar to A. torosum in the structure of the male sexual organs but differs from the latter in the following ways: higher a values (30-40 vs 17-27); longer tail (5.4-7.8 vs 4-5 anal body diam. long) and a weakly sclerotised pharyngeal bulb that is never angular in appearance. Sabatieria annulata n. sp. is most similar to the cosmopolitan species S. punctata, the main difference being the absence of punctations in S. annulata n. sp. Sabatieria annulata n. sp. also has shorter spicules (34-36 vs 41-54 μm) and shorter gubernacular apophyses (14-16 vs 20-24 μm) than S. punctata.

Two New Species

Unclear boundaries between species hinder identification in the field and in herbaria, especially in species groups that can only be distinguished on the basis of subtle morphological and ecological features. One such taxon is Ficinia indica, widespread in the Greater Cape Floristic Region, growing on deep sandy soils between sea level and 1000 m elevation. Within its range, several phylogenetically related and morphologically similar species co-occur or occupy distinct habitats. Studies in herbaria show species in the Ficinia indica complex to be largely misidentified based on the use of qualitative information. Here, we investigate whether the six taxa recognized, based on one or a few characters, are supported as distinct species based on multivariate analysis of macro-morphological data. Two of the taxa were mostly separated whereas the other four taxa overlapped in multivariate space, but all the taxa could be distinguished using a single or a combination of morphological and ecological characters. We uphold the four previously recognized taxa (Ficinia argyropus, F. elatior, F. indica, F. laevis) as species, describe two new species (F. arnoldii and F. montana), and provide a dichotomous key for their identification.

A New Species

The genus Cicadulina was established in 1926 (Bull. Ent. Res. 17, p. 43) to hold a new species, C. zeae, China, injurious to maize in Kenya Colony. Later (Bull. Ent. Res., 19, 1928, p. 66) it was shown that Balclutha mbila, Naude, recorded as transmitting the virus of streak disease of maize in Natal, also belonged to this genus, and two new species C. arachidis and C. similis were described from the Gambia, where they were reported as injurious to ground-nut and suspected of transmitting the virus of the rosette disease of that plant. Since that time Dr. H. H. Storey of the Amani Research Station has been investigating the possibility of transmission of the streak virus of maize by C. zeae. In attempting to breed strains capable of transmission of the disease certain crosses were made which showed conclusively that he was dealing with two distinct species. These species he was able to separate on the colour pattern of the abdomen. Dr. Storey has now sent to me material of both these species and a study of the genitalia corroborates his finding. One, of course, proved to be C. zeae, the other is new and I therefore propose to dedicate it to the discoverer.

Hoplias lacerdae was originally described from the rio Ribeira de Iguape, Iporanga, São Paulo State. The Hoplias lacerdae group is defined as containing generally large trahiras with the medial margins of dentaries running parallel to each other and lacking teeth on the basihyal compared to the H. malabaricus group in which the medial margins of the dentaries converge towards the mandibular symphysis and which have teeth on the basihyal. A taxonomic revision of the group based on meristic and morphometric data identified five distinct species: H. lacerdae distributed in the rio Ribeira de Iguape and rio Uruguai; H. intermedius from the rio São Francisco, upper rio Paraná basin, and rio Doce; H. brasiliensis from rivers of the Atlantic Coastal drainage from the rio Paraguaçu to the rio Jequitinhonha; H. australis new species, endemic to the rio Uruguai; and H. curupira new species present in northern South America, including the rios Negro, Trombetas, Tapajós, Xingu, Tocantins and Capim in the Amazon basin, upper rio Orinoco near the rio Casiquiare (Venezuela), and coastal rivers of Guyana and Suriname. A lectotype for Hoplias intermedius and a neotype for H. brasiliensis are designated.

The study is based on new material from the collections of the Naturalis Biodiversity Centre in Leiden (RNHM) and the Hungarian Natural History Museum (HNHM) and addresses issues in two genera: Epeus Peckham & Peckham, 1886 and Ptocasius Simon, 1885 from Thailand. Both genera are of Asian/Indomalayan origin, the latter with a diversity hotspot in the subtropical valleys of the Himalayas. Based on morphological data, we propose three new species of Epeus (Epeus daiqini sp. nov. (♂♀), Epeus pallidus sp. nov. (♀), Epeus szirakii sp. nov. (♀)) and two new species of Ptacasius (Ptocasius metzneri sp. nov. (♂♀) and Ptocasius sakaerat sp. nov. (♀)). Additionally, we redescribed E. tener (Simon, 1877) and added photographs of morphological characters. The genus Ptocasius is redefined due to the inclusion of 37 species, previously included in Yaginumaella Prószyński, 1979. Relationships and distribution of both genera are discussed in reference to molecular, morphological and distributional data, published by other authors in recent years.

The harvestman genus Bonea Roewer, 1914 and its type species B. sarasinorum Roewer, 1914 are redescribed based on the type material. In addition, two new species of Bonea from Hainan Island, China, are described and illustrated: B. zhui sp. nov. and B. tridigitata sp. nov. A new species of Lomanius Roewer, 1923 from Yunnan Province, China, is also described and illustrated: L. bulbosus sp. nov.. Keys to the 10 species of Bonea and the six species of Lomanius are provided. Paralomanius Goodnight & Goodnight, 1948 is revalidated from the synonymy of Lomanius, carrying as junior synonym Eulomanius Roewer, 1949, and containing two species from Micronesia (Paralomanius longipalpus Goodnight & Goodnight, 1948) and Philippines (Paralomanius mindanaoensis (Suzuki, 1977) new status). Bonea is transferred from the Ibaloniinae to Podoctinae. These are the first records of named species of Podoctidae from China.

Twenty-two species of Early Permian colonial rugose corals belonging to 12 genera from 10 locations in the Stikine River area in northwestern British Columbia, Canada, are described. These include three new species ofFomichevella(F. magna, F. southeri, F. bamberi); two species ofHeintzella; five species ofHeritschioides, of which three are new (H. bagleyae, H. garvinae, H. hoganae); two new species ofParaheritschioides(P. jennyi, P. wickenae); one new species questionably assigned toKleopatrina(K.?stikinensis); two new species ofPetalaxis(P. guaspariniae, P. neriae); and two new species ofLytvophyllum(L.?mongeri, L. wersoni). In addition, five new species assigned to five new genera are here namedEastonastraea complexa, Fedorowskiella simplex, Pararachnastraea lewisi, Stikineastraea thomasi, andWilsonastraea rigbyi.These corals occur in rocks forming part of the Stikine terrane, the largest tectonostratigraphic unit in western Canada. This coral fauna shows a very close affinity with that of the Lower Permian McCloud Limestone of the eastern Klamath Mountains of northern California, and there is some similarity to the Coyote Butte fauna of central Oregon. Several species compare most closely with species from Spitsbergen, but there are few similarities with any cratonal North American faunas and none with Tethyan faunas.
