Nematodes from saline and freshwater lakes of the Vestfold Hills,East Antarctica,including the description of <Emphasis Type="Italic">Hypodontolaimus antarcticus</Emphasis> sp. n.

The invertebrate fauna of many Antarctic ice-free areas, even those close to permanent research stations, can be poorly known. Here we describe some nematodes from freshwater and saline, marine-derived lakes of the Vestfold Hills, East Antarctica. The freshwater lakes contained the widespread East Antarctic endemic species, Plectus frigophilus Kirjanova, 1958. The saline lakes were inhabited by two recently described species, Halomonhystera halophila Andrássy, 2006 and Halomonhystera continentalis Andrássy, 2006, and by a new species described in this report, Hypodontolaimus antarcticus sp. n. Originally marine but now brackish Highway Lake contained a nematode fauna with both freshwater and marine-derived components. The nematode fauna of Antarctica now consists of 54 named species, 22 of which are found in East Antarctica.     

A new Spionidae (Polychaeta) from North Carolina, and a redescription of Marenzelleria wireni Augener, 1913, from Spitsbergen, with a key for all species of Marenzelleria

Marenzelleria bastropi, a new species of Spionidae (Polychaeta) from the brackish water Currituck Sound, North Carolina, is described. The new species is characterized by the great number of chaetigers between the first neuro- and notopodial hooded hooks, the extension of the nuchal organ up to the end of chaetiger 2/middle of chaetiger 3 and the presence of about 60–90 branchiate chaetigers. Marenzelleria bastropi sp. nov. is closely related to M. neglecta (Sikorski and Bick, 2004) and Marenzelleria viridis (Verrill, 1873). Marenzelleria wireni Augener, 1913 is described here for the first time from western Spitsbergen. Adult specimens are investigated and compared with specimens from other areas of distribution. A key for subadult and adult specimens of all Marenzelleria species is provided.     

Three new species of <Emphasis Type="Italic">Anthocephalum</Emphasis> Linton, 1890 (Cestoda: Tetraphyllidea) from dasyatid stingrays of the Gulf of California

Three new species of Anthocephalum Linton, 1890 are described from dasyatid stingrays collected in the Gulf of California. Anthocephalum michaeli n. sp. is described from Dasyatis longus (Garman). This species most closely resembles A. alicae Ruhnke, 1994, but differs from this species in proglottid number. A. lukei n. sp. is also described from D. longus. This new species is most similar to A. cairae Ruhnke, 1994, but differs from that species in marginal loculi number and number of proglottids. The third new species, A. currani n. sp., is described from D. brevis (Garman). This species is most similar to A. centrurum (Southwell, 1925) Ruhnke, 1994, but differs from that species in marginal loculi number, number of testes and ovarian length. Phyllobothrium kingae Schmidt, 1978 is also consistent in morphology with species of Anthocephalum and is transferred to this genus, forming the new combination Anthocephalum kingae n. comb. This species most closely resembles A. michaeli n. sp., but differs in testicular shape. This brings the total number of species of Anthocephalum to nine. The transfer of the species Phyllobothrium arctowskii Wojciechowska, 1991, P. georgiense Wojciechowska, 1991, P. rakusai Wojciechowska, 1991 and P. siedleckii Wojciechowska, 1991 to Anthocephalum is not warranted, as these four species lack a posteriorly recurved cirrus-sac and a sinuous vagina, and have vitelline follicles uninterrupted by the ovary. Of the nine known species, all are parasitic in batoid fishes, and six are found in species of Dasyatis Garman. The phylogenetic status of Anthocephalum species in relationship to Rhinebothroides Mayes, Brooks & Thorson, 1981, Pararhineothroides Zamparo, Brooks & Barriga, 1999 and other rhinebothriin taxa is discussed.     

Four new species of <Emphasis Type="Italic">Aloe</Emphasis> (Aloaceae) from Ethiopia,with notes on the ethics of describing new taxa from foreign countries

Subsequent to the treatment of the Aloaceae, with 38 species of Aloe, in the Flora of Ethiopia (Sebsebe Demissew & Gilbert 1997), four more species, Aloe bertemariae Sebsebe & Dioli (2000), A. friisii Sebsebe & M. G. Gilbert (2000), A. clarkei L. E. Newton (2002) and A. elkerriana Dioli & T. A. McCoy (2007) have been described from that country. Here four additional new species are described: Aloe benishangulana Sebsebe & Tesfaye from near Assosa, Benishangul-Gumuz in Welega floristic region; A. ghibensis Sebsebe & Friis from the Ghibe Gorge, Kefa floristic region; A. weloensis Sebsebe from near Dessie in Welo floristic region and A. welmelensis Sebsebe & Nordal along the Welmel River in Bale floristic region. The phytogeographical positions of the new species are assessed by comparison with the previously known species. Complications with the deposition of type material of A. clarkei and A. elkerriana is used to raise various issues regarding the ethics of describing new taxa from foreign countries.     

Species of <Emphasis Type="Italic">Teratorhabditis</Emphasis> (Osche, 1952) Dougherty, 1953 (Nematoda:Rhabditida) from sewage and manure samples in India including a discussion on relationships within the genus

Three species of the genus Teratorhabditis (Osche, 1952) Dougherty, 1953 collected from sewage and manure samples of North India are described. The species T. andrassyi Tahseen & Jairajpuri (1988) synonymised by Sudhaus (1991) has been reinstated and is characterized by oviparous females having bluntly rounded lips with labial sensilla not raised beyond labial contour; lip margins and axils heavily cuticularised; three lines in lateral field; considerably wide and tubular stoma having swollen metastegostomal walls with prismatic inner lining bearing five teeth on each plate; basal bulb with usually single haustrulum; tail conoid with a terminal spike; eggs with ridged shells and males with 40–45% distally-fused spicules and a smooth, non-indented bursa having slender papillae in 2/4 + p + 3 configuration. Other populations identified as T. synpapillata and T. palmarum Gerber and Giblin-Davis (1990) are reported for the first time from India. An identification key to species is provided. Relationships within the genus are discussed. Electronic supplementary material Supplementary material is available for this article at and accessible for authorised users Handling editor: K.

A Voucher Specimen for <Emphasis Type="Italic">Macaca munzala</Emphasis>: Interspecific Affinities,Evolution, and Conservation of a Newly Discovered Primate

Sinha, A., Datta, A., Madhusudan, M. D., & Mishra, C. (2005. Macaca munzala: A new species from western Arunachal Pradesh, northeastern India. International Journal of Primatology, 26, 977–989) discovered Arunachal macaques (Macaca munzala), a species new to science, in the eastern Himalaya of Arunachal Pradesh in northeastern India. They depicted the holotype and paratypes of the species in photographs, and a specimen of the species had been unavailable for preservation and examination. In March 2005, we obtained an entire specimen of an adult male Macaca munzala, which we propose as a voucher specimen for the species. We provide detailed morphological and anatomical measurements of the specimen and examine its affinities with other macaques. Macaca munzala appears to be unique among macaques in craniodental size and structure, baculum, and aspects of caudal structure, while exhibiting affinities with the other members of the sinica-group to which it belongs. We summarize our insights on the origins and phylogeny of Macaca munzala. Finally, we review the current conservation status of the macaques, which are threatened by extensive hunting in the only 2 districts of Arunachal Pradesh where they are documented to occur.     

A synoptic revision of Dacryodes (Burseraceae) in Africa, with a new species from Central Africa

Summary  A synoptic revision is presented for the genus Dacryodes Vahl in Africa. The studies are based on examination of herbarium material. Eighteen species are recognised, including two not well known due to poor material. The new species Dacryodes villiersiana Onana is described and illustrated. The conservation status of the species is discussed following the categories and criteria of IUCN (2001).     

Synonymy of two species of the genus <Emphasis Type="Italic">Platycephalus</Emphasis> and validity of <Emphasis Type="Italic">Platycephalus westraliae</Emphasis> (Teleostei: Platycephalidae)

The type specimens of platycephalid Platycephalus endrachtensis Quoy and Gaimard 1825 are regarded as being conspecific with Platycephalus arenarius Ramsay and Ogilby 1886, so the latter becomes a junior synonym. This species is characterized as having a caudal fin with four or more longitudinal dark bands and lacking a yellow blotch. It is also found that Platycephalus westraliae (Whitley 1938), which had been considered to be a junior synonym of Platycephalus bassensis Cuvier 1829, is a valid species. Specimens that recently had been mistakenly identified as “P. endrachtensis,” having the caudal fin with three or four longitudinal dark bands and a yellow blotch on the upper lobe, should be referred to P. westraliae.     

Ceiba rubriflora (Malvaceae: Bombacoideae), a new species from Bahia, Brazil

Summary   Ceiba rubriflora Carv.-Sobr. & L. P. Queiroz, a new species of Malvaceae subfamily Bombacoideae from the State of Bahia, Brazil, is described and illustrated. It is considered to be endemic to calcareous outcrops in the valley of the Rio S?o Francisco, in the western region of the state. Notes on distribution, ecology and phenology are given. Relationships with related species are discussed and an addition to the key to species of Ceiba Mill. published by Gibbs & Semir (2003) are provided.     

<Emphasis Type="Italic">Neoskrjabinolepis nuda</Emphasis> n. sp. from shrews on Sakhalin Island,Russia, with a taxonomic review of <Emphasis Type="Italic">Neoskrjabinolepis</Emphasis> Spasskii, 1947 (Cestoda: Cyclophyllidea: Hymenolepididae)

Neoskrjabinolepis (Neoskrjabinolepidoides) nuda n. sp. is described from the shrews Sorex unguiculatus (type-host), S. gracillimus, S. isodon and S. caecutiens on Sakhalin Island, Russia. The new species is characterised by: rostellar hooks 40–44 μm long and provided with small epiphyseal thickening of the handle; a long (95–100 μm) cirrus consisting of basal region with claw-shaped spines, a parabasal region with thin needle-shaped spines and an unarmed distal region; a cirrus-sac extending well into the median field; and 15–22 eggs per gravid uterus. A review of the species of Neoskrjabinolepis Spasskii, 1947 is presented. Currently, this genus includes nine species and is divided in two subgenera on the basis of strobilar development, which is gradual in the subgenus Neoskrjabinolepis (four species) and serial in the subgenus Neoskrjabinolepidoides Kornienko, Gulyaev & Mel’nikova, 2006 (five species). An amended generic diagnosis and an identification key to Neoskrjabinolepis spp. are presented.     

Taxonomic review of the genus <Emphasis Type="Italic">Cottiusculus</Emphasis> (Cottoidei: Cottidae) with description of a new species from the Sea of Japan

A taxonomic review of the cottid genus Cottiusculus Jordan and Starks 1904 established three species, C. nihonkaiensis sp. nov., C. schmidti, and C. gonez. Cottiusculus nihonkaiensis sp. nov., which had been previously confused with C. schmidti, is described on the basis of 32 specimens (44.8–77.9 mm, SL) collected from the Sea of Japan. The new species is very similar to C. schmidti in having a curved barbless uppermost preopercular spine and the lateral line extending past the caudal fin base, but is distinguishable as follows: nasal spines simple or sometimes weakly bicuspid (vs. deeply bicuspid in C. schmidti); first dorsal fin not elongated in either males or females (vs. elongated in males); ventral lateral and lateral line cirri present (vs. absent). The former is known from the Sea of Japan coasts of Hokkaido, Honshu, Kyushu and the Korean Peninsula, and Volcano Bay, Hokkaido, and the latter from the Pacific coast of Tohoku District, Japan. Cottiusculus gonez, known from the Sea of Japan, Sea of Okhotsk and Pacific coast of Hokkaido, is characterized by having a simple nasal spine, the uppermost preopercular spine almost straight with two small cusps dorsally, posterior cusp barbed, and the lateral line almost reaching to the caudal fin base. A lectotype of C. gonez is designated here. Sequence differences in the cytochrome b gene among the above three species of Cottiusculus are also presented.     

A new species of <Emphasis Type="Italic">Penopus</Emphasis> (Teleostei: Ophidiidae) from the Ryukyu Trench,the West Pacific,with remarks on <Emphasis Type="Italic">Penopus microphthalmus</Emphasis>

The bathyal genus Penopus (Ophidiidae) is revised based on 23 specimens. One specimen from the Ryukyu Trench represents a new species, Penopus japonicus. The remaining 22 specimens were found on both sides of the Atlantic Ocean, and neither 28 meristic and morphometric characters nor several morphological characters show any differences between the two populations. This supports Séret (1988), who considered Penopus macdonaldi Goode and Bean 1896 a junior synonym of Penopus microphthalmus (Vaillant 1888). The new Japanese species can be separated from the Atlantic species by having fewer rays in the dorsal (117 vs. 135–158) and anal (89 vs. 106–122) fins, the squamation of the head restricted to the middle part of the preopercle versus the squamation covering the dorsum, preopercle and the opercle in part, a distinct spine behind the posterior nostril versus the spine hardly visible and 9 spines on the hind margin of the preopercle versus 4–7 spines.     

A new species of <Emphasis Type="Italic">Litomosoides</Emphasis> Chandler, 1931 (Nematoda: Filarioidea) from the long-nosed hocicudo <Emphasis Type="Italic">Oxymycterus nasutus</Emphasis> Waterhouse (Rodentia: Cricetidae) in Uruguay

A new species of Litomosoides Chandler, 1931 was collected from the abdominal cavity of Oxymycterus nasutus Waterhouse (Rodentia: Cricetidae) in the grassland of the Departamento Rocha, Uruguay. Litomosoides nasuti n. sp. belongs to the ‘sigmodontis group’, and is characterised by: salient amphids; two ventral and one dorsal labial papillae, but no cephalic papillae; a buccal capsule with a transparent anterior segment and an annular asymmetrical thickening; a muscular oesophagus; a bottle-shaped buccal cavity; the male with symmetrically situated cloacal papillae (one pair ad-cloacal and three pairs post-cloacal); phasmids displaced laterally to the longitudinal axis; and microfilariae without terminal nuclei in the tail tip. It resembles five known species; three of which have been recovered from Oxymycterus spp. in neighbouring countries. However, the new species can be differentiated from L. sigmodontis Chandler, 1931 by the shape and size of the buccal capsule; from L. navonae Notarnicola, 2005 by the muscular oesophagus; from L. legerae Bain, Petit & Berteaux, 1980 by the length of the oesophagus and the cephalic papillae; from L. anguyai Notarnicola, Bain & Navone, 2002 by the absence of lappets in the female tail; and from L. oxymycteri Notarnicola, Bain & Navone, 2000 by absence of pre-cloacal papillae. L. legerae from O. quaestor and L. sigmodontis from Sigmodon hispidus in North America are closely related species, as indicated by Brant & Gardner’s phylogenetic tree based on morphological characters. However, a new analysis is needed to include the recently described Argentinean species for a better understanding of the diversification of this genus.     

A revision of the Haploporinae Nicoll, 1914 (Digenea: Haploporidae) from mullets (Mugilidae): <Emphasis Type="Italic">Saccocoelium</Emphasis> Looss, 1902

Saccocoelium Looss, 1902 is revised and a key to its recognised species is presented. S. obesum Looss, 1902 (type-species) and S. tensum Looss, 1902 are redescribed based on material from Liza spp. (Pisces: Mugilidae) in Spanish Mediterranean and, in the case of the former, Bulgarian Black Sea waters. Two new species, S. cephali n. sp. and S. currani n. sp., are described from Mugil cephalus L. in Spanish Mediterranean waters. S. gohari Ramadan, Saoud, Ashour & Mansour, 1989b is recognised and commented upon. Lecithobotrys helmymohamedi Ramadan, Saoud, Ashour & Mansour, 1989a, S. portsaidensis El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992, S. saoudi El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992, Neosaccocoelium aegyptiacus El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992 are considered to be synonyms of S. tensum and Neosaccocoelium El-Shahawi, El-Gindy, Imam & Al-Bassel, 1992 a synonym of Saccocoelium. S. obesum, S. tensum and the two new species are compared morphometrically and distinguished by univariate and multivariate analyses. Lecithobotrys mugilis Rekharani & Madhavi, 1985 is transferred to Unisaccus Martin, 1973 as U. mugilis (Rekharani & Madhavi, 1985) n. comb., and Lecithobotrys sprenti Martin, 1973 [=  Saccocoelium sprenti (Martin, 1973) Overstreet & Curran, 2005] is transferred to Unisaccus as U. sprenti (Martin, 1973) n. comb. S. megasacculum Liu, Wang, Peng, Yu & Yang, 2004 is transferred to Elliptobursa Wu, Lu & Zhu, 1996 as E. megasacculum (Liu, Wang, Peng, Yu & Yang, 2004) n. comb. S. tripathi Dutta, 1995 (syn. Saccocoelium tripathi Datta & Manna, 1998) is considered to be a species inquirenda.

Cold storage and cryopreservation of hairy root cultures of medicinal plant <Emphasis Type="Italic">Eruca sativa</Emphasis> Mill., <Emphasis Type="Italic">Astragalus membranaceus</Emphasis> and <Emphasis Type="Italic">Gentiana macrophylla</Emphasis> Pall.

To explore the possibility of an effectively long-term preservation of the germplasm of the HR lines of medicinal plant Astragalus membranaceus, Gentiana macrophylla Pall., and Eruca sativa Mill., both cold storage and cryopreservation approaches were attempted and compared. After 5-month cold storage on half strength Murashige and Skoog (1962) (1/2 MS) agar medium (AM), up to 82.9, 75.7, and 100% of the A. membranaceus, G. macrophylla and E. sativa hairy roots (HRs) recovered growth, respectively. The survival rates of A. membranaceus and G. macrophylla HRs significantly decreased, whereas that of E. sativa HR was unchanged with the addition of increased levels of exogenous abscisic acid (ABA) during cold storage. Using the encapsulation–vitrification (EV) method for cryopreservation, the G. macrophylla HRs died, whereas up to 6 and 73% of the A. membranaceus and E. sativa HRs survived, respectively. The HR lines evaluated with both methods showed no significant differences in morphology and growth rate compared with controls that were not subjected to preservation methods. These results suggest that cold storage is a more suitable alternative for the HR lines of the three studied plant species and that specificity of plant species have profound effects on the effectiveness of preservation.     

The Miocene <Emphasis Type="Italic">Keramidomys</Emphasis> (Rodentia,Eomyidae) from the Sandelzhausen locality (Germany)

In this note the taxonomic position of the tiny eomyid genus Keramidomys (Hartenberger, 1967) from the Early/Middle Miocene boundary locality of Sandelzhausen in the Bavarian Upper Freshwater Molasse is reexamined. As the chronological dating of the Sandelzhausen fossil site has been modified in the past from formerly the Neogene mammal unit MN6 to now MN5 and thanks to new abundant material this rodent is compared with other European forms. It is shown that the Sandelzhausen eomyid must be called K. thaleri Hugueney & Mein, 1968 on the basis of several morphological dental differences from K. carpathicus Schaub & Zapfe, 1953. This rodent seems to be an immigrant from East Asia into Europe. Even if K. thaleri is known in many European localities, all correlated to MN5, it is always a rare element of European rodent faunas. Differentiation from K. carpathicus is not easy and requires a sufficiently large sample.
