Sagum posteli Delamare-Deboutteville & Nunes-Ruivo, 1954 (Copepoda: Siphonostomatoida: Lernanthropidae) parasitic on Epinephelus aeneus (Geoffroy Saint-Hilaire) in Turkish waters, with a key to the species of Sagum Wilson, 1913

Sagum posteli Delamare-Deboutteville & Nunes-Ruivo, 1954 (Copepoda: Lernanthropidae) is reported from the white grouper Epinephelus aeneus Geoffroy Saint-Hilaire caught off the Turkish Mediterranean coast. This documents the first discovery of this species in the Mediterranean and is only the second record. The species is redescribed from adult females and the cephalothoracic limbs are described for the first time. The valid species of the genus Sagum Wilson, 1913 are reviewed, and the poorly described species S. poeyi Ortiz, Lalana & Suarez, 2003 is relegated as a junior synonym of S. texanum Pearse, 1952, described from the same host. A key is provided to females of the ten valid species of Sagum and the known hosts for all species are summarised.     

The genus Argulus (Crustacea: Branchiura) in Africa: two new species,A. fryeri and A. gracilis,the previously undescribed male of A. brachypeltis Fryer and the identity of the male described as A. ambloplites Wilson

Two new species of Argulus Müller, 1785 (Crustacea: Branchiura) are described from Africa. A. fryeri n. sp., parasitic on an unknown fish species collected from Lake Turkana, Kenya, is characterised by: deep antero-lateral depressions which delimit a pronounced frontal region; robust, square second maxillae ornamented with numerous small, simple scales; and the shape of the respiratory areas. The most distinctive features of A. gracilis n. sp., parasitic on Auchenoglanis occidentalis var. tanganicanus collected from Lake Tanganyika, are the anterior spines on the first antennae and the shape of the respiratory areas. A. brachypeltis Fryer, previously known only from the female, is characterised by: a narrow, elongate body with foreshortened carapace lobes; small, slender terminal spines on the first antennae; and short terminal segments on the second maxillae with minute claws. The identity of the male described as A. ambloplites Wilson is discussed and renamed A. confusus nom. nov.     

Two new species and one new record of Clavella (Copepoda: Lernaeopodidae) from inshore fishes of Antofagasta,Chile

Summary Clavella applicata n. sp. and C. caudata n. sp. are described and illustrated. Both species are parasitic on the fins (the latter also on the inner surface of the operculum) of Anisotremus scapularis (Tschudi), an inshore teleost fish from Antofagasta, Chile. Both new species can be distinguished from their congeners, and from each other, by various details of their appendages. C. caudata is unique in possessing modified uropods. The dorsal position of these appendages suggest that the Clavella-branch of Lernaeopodidae is related more closely to the Charopinus-branch than to Brachiella-branch of the family. C. parva Wilson, 1912, is recorded for the first time from Chilean waters, where it was found on the caudal fin of Mugiloides chilensis (Molina). ac]19840504     

714. ROSA GLOMERATA

Rosa glomerata Rehder & Wilson (Rosaceae, sect. Synstylae) a rampant climber from western China, is illustrated and described. Related species are compared, and their cultivation is discussed.     

Four new species of <Emphasis Type="Italic">Aulonastus</Emphasis> Kethley, 1970 (Acari: Syringophilidae) from North American passerines

Four new species belonging to Aulonastus Kethley, 1970 (Acari: Prostigmata: Syringophilidae), which are found inside the quills of body feathers of North American passerines (Aves: Passeriformes), are described and figured: A. emberizicus n. sp. from Ammodramus savanarum (Gmelin) (Emberizidae) (type-host) in Texas, Zonotrichia atricapilla (Gmelin) (Emberizidae) in California and Passerculus sandwichensis (Gmelin) (Emberizidae) in Texas; A. euphagus n. sp. from Euphagus cyanocephalus (Wagler) (Icteridae) in California; A. pirangus n. sp. from Piranga ludoviciana (Wilson) (Cardinalidae) in California; and A. sturnellus n. sp. from Sturnella magna (Linnaeus) (Icteridae) in Texas. A key to females of the known species of Aulonastus is presented.     

New Podonominae from Japan,Boreochlus longicoxalsetosus sp. n. (Diptera: Chironomidae) with a Key to Species of the Genus

During the survey of chiromonid midges from Kyushu, the authors found a new species of Podonominae (Chironomidae), Boreochlus longicoxalsetosus. The male imago of this new species is described and illustrated. This constitutes the third record of the subfamily Podonominae, and the second species of the genus from Japan. The new species has very long notable setae lying on the dorsomedial surface distal to the volsella, which are never seen in the other Boreochlus species. A key to species of the genus in the world is given.     

First record of the taxon Echinopsyllus (Copepoda,Harpacticoida, Ancorabolidae) from the deep sea of Campos Basin,Brazil, with the description of three new species and their contribution to phylogenetic analysis

New species assignable to the formerly monotypic genus Echinopsyllus (Copepoda, Harpacticoida, Ancorabolidae) are described from the continental slope of Campos Basin off Brazil in the south‐western Atlantic. Echinopsyllus brasiliensis sp. nov. , Echinopsyllus nogueirae sp. nov. , and Echinopsyllus grohmannae sp. nov. differ from Echinopsyllus normani Sars, 1909 in the cephalothorax having two instead of three pairs of lateral processes, first pair of dorsal cephalothoracic processes being smaller than second pair, second pair of dorsal cephalothoracic processes branched, and segmentation and setation of the swimming legs. The discovery of new species of Echinopsyllus extends the distributional range of the genus to the southern hemisphere and is further evidence for the formerly unexpected wide genus‐level distribution of Ancorabolidae in the world's oceans. The phylogenetic position of Echinopsyllus within Ancorabolinae is discussed. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 156 , 52–78.     

Tetrameres (Gynaecophila) aspicula n. sp. (Nematoda: Tetrameridae), a proventricular parasite of the white-faced ibis Plegadis chihi in Argentina

Tetrameres (Gynaecophila) aspicula n. sp. is described from the proventriculus of the white-faced ibis Plegadis chihi (Vieillot) (Ciconiiformes, Threskiornithidae) from Argentina. The new species is characterised by the absence of spicules, by possessing two ventral rows of extremely small spines in males, extending along the second half of body length, and by the tiny, very feebly developed postcloacal papillae. T. (G.) aspicula n. sp. is compared to the remainder of the species in the subgenus as well as to other species of Tetrameres which lack or possess feebly developed spines. The absence of spicules is a character shared with two other species in the genus, T. (G.) gynaecophila and T. (G.) deccani,from which the new species differs in body size, the arrangement of caudal papillae and the somatic spination in males. A pair of somatic papillae, previously unreported in species of this genus, was found just on or ventral to the lateral line at various regions of the body length. The homology of these structures to other paired somatic papillae described in nematodes is discussed.     

Two new British species of Halticoptera (Hymenoptera: Chalcidoidea,Pteromalidae)

The female of a new species of Halticoptera is described from a single specimen from Britain, and the male and female of a second new species are described from material from Britain and Czechoslovakia. Halticop-terina triannulata is recorded from Britain for the first time.     

Description of a new Nipergasilus species (Family: Ergasilidae) from the gills of grey mullet

A new Nipergasilus species is described from the gills of the grey mullet Valamugil cunnesius from several localities in India and Pakistan. The new species is closely related to Nipergasilus bora (Yamaguti, 1939) which is also recorded here on three species of grey mullet. The genus Nipergasilus is redefined in order to accommodate the second species.     

A new species of Mesopropithecus (Primates, Palaeopropithecidae) from Northern Madagascar

We diagnose new subfossil specimens belonging to the extinct palaeopropithecid, Mesopropithecus,from several caves at the Ankarana massif in northern Madagascar. They include three partial crania with mandibles, and the first vertebrae, ribs, clavicle, pelvis, ulna, and hand and foot bones of Mesopropithecusever found. Several other postcranial elements are known for this northern variant of Mesopropithecusand for previously described species from central and southern Madagascar. The new materials cannot be accommodated in either currently recognized species of this genus and are,hereby, given the name Mesopropithecus dolichobrachion. M. dolichobrachionis the second new species of extinct subfossil lemur to be found in the caves of Ankarana. It is unlike the two previously described species of this genus primarily in its larger size, different limb proportions, and aspects of its long bone morphology. Most notable is the fact that this is the only species of Mesopropithecuswith the forelimb longer than the hind limb— hence the name, the “long-armed” Mesopropithecus.Various characteristics place M. dolichobrachionphenetically closest (of species belonging to Mesopropithecus)to Babakotia radofilai, Archaeoindris,and Palaeopropithecus.If these similarities are derived specializations rather than primitive for palaeopropithecids, a new generic name will be required.     

Further investigations of the mite genus <Emphasis Type="Italic">Syringophiloidus</Emphasis> Kethley, 1970 (Acariformes: Syringophilidae) from North American passerines

Four new syringophilid species of Syringophiloidus Kethley, 1970 are described from North American passerines: S. zonotrichia n. sp. from Zonotrichia albicolis (Gmelin) (Emberizidae) on Texas; S. jackowiaki n. sp. from Poecile carolinensis (Auduborn) (Paridae) in Texas; and S. xanthocephalus n. sp. from Xanthocephalus xanthocephalus (Bonaparte) (Icteridae) and S. agelaius n. sp. from Agelaius phoeniceus Linnaeus (Icteridae), both from Arizona. Spizella breweri (Cassin) (Emberizidae) from California is a new host for Syringophiloidus sialius Skoracki, Flannery & Spicer, 2009; and Melospiza lincolnii (Auduborn) (Emberizidae) from Texas and Vermivora ruficapilla (Wilson) (Parulidae) from California are new hosts for S. seiuri (Ckark, 1964). S. daberti Bochkov, Fain & Skoracki, 2004 from Passerina ciris Linnaeus (Cardinalidae) is recorded in the USA for the first time. A table with the host associations and distribution of all of the North American species of Syringophiloidus is given.     

A new species of <Emphasis Type="Italic">Laboulbenia</Emphasis> parasitic on tiger beetles

Laboulbenia phaeoxanthae sp. nov. (Ascomycota: Laboulbeniales) parasitic on the tiger beetle Phaeoxantha aequinoctialis bifasciata (Coleoptera: Carabidae: Cicindelinae) from Brazil is described. The new species seems to be closely related to Laboulbenia pheropsophi, but can be distinguished from the latter by the much more slender and elongate habit, and by the different structure of the appendages. The new species is only the second Laboulbeniales species reported on tiger beetles. The widespread Laboulbenia variabilis was previously recorded on Tetracha fulgida from Ecuador.     

The true identity of Obama (Platyhelminthes: Geoplanidae) flatworm spreading across Europe

Since 2008 there have been many records in Europe (British Isles, Spain, France, Italy) of a large terrestrial planarian morphologically very similar to the Brazilian species Obama marmorata. Sequences of mitochondrial (Cox1) and nuclear (18S, 28S, ITS‐1 and EF) genes from European specimens and some from Brazil indicate that they belong to a species different from that of other specimens also collected in Brazil. Moreover, the phylogenetic results show that they are not sister‐species. Histological sections of both Brazilian and European specimens reveal subtle morphological differences between the two species. Obama marmorata is confined to Brazil, and the second, herein described new species, O bama nungara sp. nov. , is found in Brazil and Europe. These cryptic species may be syntopic in areas in Brazil. The new species occurs in human‐modified environments both in Brazil and in Europe. We also conclude that the specimens from Spain and Argentina identified previously as Obama marmorata belong to the new species.     

<Emphasis Type="Italic">Angiostoma margaretae</Emphasis> n. sp (Nematoda: Angiostomatidae), a parasite of the milacid slug <Emphasis Type="Italic">Milax gagates</Emphasis> Draparnaud collected near Caledon,South Africa

Angiostoma margaretae n. sp. (Angiostomatidae) is described from the oesophagus of the slug Milax gagates Draparnaud collected near Caledon in the Western Cape Province of South Africa. The new species closely resembles another parasite of a milacid slug, A. milacis Ivanova & Wilson, 2009, with a similar head, stoma and spicule shape, the presence of distally outstretched ovaries, coiled oviducts, the same number of caudal papillae and enlarged rectal glands. However, A. margaretae differs from the latter by having: a shorter, wider tail with a rounded vs pointed tip; the distal parts of both ovaries with a particular hook-like shape due to an expansion closely following the short initial zone; ovoviparous females; and a different arrangement of male papillae. A. margaretae is comparable with A. limacis Dujardin, 1845, A. asamati (Spiridonov, 1985), A. coloaense (Pham Van Luc, Spiridonov & Wilson, 2005) and A. stammeri (Mengert, 1953), which have a similar stoma shape and size, but can be readily differentiated by the presence of distally outstretched vs reflexed ovaries and the presence vs lack of enlarged rectal glands. The new species has a similar arrangement of the ovaries to A. kimmeriense Korol & Spiridonov, 1991 and A. zonitidis Ivanova & Wilson, 2009, but is clearly differentiated by the lack of an off-set lip region and presence of a large bowl-shaped vs tubular stoma and less numerous male caudal papillae (seven pairs vs nine in A. kimmeriense and 10 in A. zonitidis).     

Haramonas viridissp. nov. (Raphidophyceae, Heterokontophyta), a new sand-dwelling raphidophyte from cold temperate waters

A new, marine, sand‐dwelling raphidophyte from Sylt, Germany, Haramonas viridis Horiguchi et Hoppenrath sp. nov. is described. This represents a second species in the previously monotypic genus Haramonas, which was originally described from a sand sample from a mangrove river mouth in tropical Australia, based on the type species, H. dimorpha. This new species from a cold temperate region: (i) possesses a tubular invagi‐nation in the posterior part of the cell; (ii) produces copious amounts of mucilage in culture; (iii) possesses both motile and non‐motile stages in its life cycle; and (iv) has overlapping discoidal chloroplasts, all of which are diagnostic features of the genus Haramonas. Therefore, it is indisputable that this species belongs to this genus. However, the species from Sylt differs from the type species of the genus in: (i) having a larger cell size; (ii) possessing a larger number of chloroplasts; and (iii) being greenish in color. The ultrastructural study revealed that the structure of the tubular invagi‐nation was the same as that of the type species.     

Three species of Trebius Krøyer, 1838 (Copepoda: Siphonostomatoida) parasitic on Pacific elasmobranchs

The paratypes of Trebius akajeii Shiino, 1954, originally collected from Dasyatis akajei (Müller & Henle) at Owase, Japan, and the paratypes and newly collected specimens of T. latifurcatus Wilson, 1921, previously collected from Urolophus and Myliobatis at Venice, California, are redescribed. New host records for T. latifurcatus are: Torpedo californica Ayres, Squatina californica Ayres, Rhinobatos productus (Ayres), Platyrhinoides triseriata (Jordan & Gilbert), Raja inornata (Jordan & Gilbert) and Gymnura marmorata (Cooper). A new species, Trebius heterodonti, is described from the horn shark Heterodontus francisci (Girard) collected from southern California waters. These three species of Trebius are apparently closely related to each other. Diagnostic characters of the species are provided along with a discussion on the taxonomic value of selected features.     

Revision of genus Melamphaes (Melamphaidae). II. Multi-Raker species: M. polylepis, M. falsidicus sp. nova, M. pachystomus sp. nova, M. macrocephalus, M. leprus

The second part of the publication is devoted to the Melamphaes species (family Melamphaidae), which are characterized by 20 and more rakers on the first gill arch, by seven soft rays in the ventral fin, by absence of a temporal spine, by 14–15 rays in the pectoral fin, and by 11 abdominal vertebrae. M. polylepis is characterized by circumtropical range (Atlantic Ocean, Indian Ocean, western and central Pacific Ocean). Newly described species M. falsidicus is described from the northern Atlantic Ocean, where it was sampled between 34°N and 58°N. Before, this species was defined as M. microps. Another newly described species, M. pachystomus, is described along the Peruvian Coast. M. macrocephalus is redescribed. This species inhabits the eastern tropical Pacific Ocean (approximately between 30°N and 23°S). One of the studied specimens of M. macrocephalus was characterized by larger body size (SL = 128 mm) than was described before for this species. M. leprus is known currently by single findings from the eastern tropical Atlantic Ocean (between 11°N and 4°S). This species was also found in the samples obtain in the Gulf of Guinea.
