<Emphasis Type="Italic">Grammatorcynicola</Emphasis> n. g. (Bucephalidae: Dolichoenterinae) from <Emphasis Type="Italic">Grammatorcynus</Emphasis> spp. (Scombridae) on the Great Barrier Reef,Australia

A new trematode genus, Grammatorcynicola n. g. (Bucephalidae: Dolichoenterinae), and two new species, G. brayi n. sp. and G. nolani n. sp. from the intestines of the scombrids, Grammatorcynus bicarinatus and Gr. bilineatus respectively, are reported from the Great Barrier Reef, Australia. Grammatorcynicola n. g. is placed in the Dolichoenterinae, as the pharynx is in the anterior quarter of the body, the caecum is tube-like and extends to the posterior quarter of the body, the cirrus-sac is small relative to the size of the worm when compared with other bucephalids and the pars prostatica is curved. Grammatorcynicola n. g. differs from other dolichoenterine genera in having a simple sucker-like rhynchus, the ovary anterior to the testes and by not having a particularly thick cirrus-sac wall.     

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 new species of <Emphasis Type="Italic">Macroptilium</Emphasis> (Benth.) Urb. (<Emphasis Type="Italic">Leguminosae</Emphasis>: <Emphasis Type="Italic">Papilionoideae</Emphasis>: <Emphasis Type="Italic">Phaseolinae</Emphasis>) from North-Eastern Brazil

Summary  A new species of Macroptilium sect. Microcochle (Benth.) J. A. Lackey is herein described from the states of Piauí and Bahia, Brazil. Macroptilium cochleatum is characterized by few-flowered inflorescences, calyx teeth longer than the tube, a tightly four-coiled keel, and linear, patent fruits. The discovery of this unique Macroptilium species, with its distally coiled keel, expands the diagnostic features of the genus. A key to the Brazilian species of sect. Microcochle is provided.     

<Emphasis Type="Italic">Spicocleidus namae</Emphasis> n. g., n. sp. (Monogenea: Dactylogyridae) on <Emphasis Type="Italic">Chanda nama</Emphasis> (Hamilton) from Lucknow,India

Spicocleidus n. g. is proposed for S. namae n. sp., a new monogenean collected from the gills of an ambassid, Chanda nama (Ham.), in the River Sai near Lucknow, Uttar Pradesh, India. The new genus is characterised by a pair of modified dorsal anchors (spikes), the absence of a dorsal bar, alate lateral expansion of the anterior haptor and the post-ovarian position of the testis.     

A new acuariid nematode, <Emphasis Type="Italic">Syncuaria mackoi</Emphasis> n. sp. (Spirurida), from <Emphasis Type="Italic">Ciconia nigra</Emphasis> (L.) (Ciconiiformes: Ciconiidae) in Europe

Syncuaria mackoi n. sp. is described, based on light and scanning electron microscopy, from the stomach of the black stork Ciconia nigra in Bulgaria. The new species is characterised by: body length 7.18–8.30 mm (males) and 10.13–11.40 mm (females); cordons anastomosing about the level of the middle of the muscular oesophagus and consisting of delicate cuticular plates; bifurcate deirids 7–9 μm long; lateral longitudinal cuticular band-like swellings; nine pairs of pedunculate caudal papillae, i.e. four precloacal and five postcloacal, the latter forming two groups (2 + 3); sixth pair of postcloacal papillae sessile; left spicule 854–907 μm long; right spicule 138–154 μm in length, with a curved distal end resembling a horn and a short lateral projection at some distance from its tip; and vagina vera provided with an anteriorly-directed blind appendix. The specimens identified as S. ciconiae (Gil’bert, 1927) by Macko (1964) from C. nigra in Slovakia are considered as belonging to S. mackoi. A pair of small cupolae situated dorsally and ventrally between bases of cordons of the new species is described for the first time in this genus; they are recognised as homologous to the pair of spines in the same position previously described in S. diacantha Petter, 1961 and S. plegadisi Digiani, 1999.     

<Emphasis Type="Italic">Sanguinicola maritimus</Emphasis> n. sp. (Digenea: Sanguinicolidae) from Labridae (Teleostei: Perciformes) of southern Australian waters

A new species of Sanguinicola Plehn, 1905 is described from the marine teleosts Notolabrus parilus (Richardson) and N. tetricus (Richardson) (Perciformes: Labridae) from Western Australian and Tasmanian waters. This host distribution is strikingly anomalous; however, the present material fulfils the morphological criteria of Sanguinicola. S. maritimus n. sp. differs from previously described species in having the combination of a body 1,432–1,701 μm long, the oesophagus 18.3–21.7% of the body length, the testis occupying 42.8–52.3% of the body length, an oviducal seminal receptacle and Mehlis’ gland present, ovoid eggs, and vitelline follicles that extend anteriorly past the nerve commissure, laterally past the lateral nerve chords and posteriorly to the anterior margin of the cirrus-sac. S. maritimus also lacks a protrusible anterior proboscis. It also differs in the combination of host and geographical location, being the first Sanguinicola species from a marine teleost and the first from Australian waters.     

<Emphasis Type="Italic">Adlardia</Emphasis><Emphasis Type="Italic">novaecaledoniae</Emphasis> n. g., n. sp. (Digenea: Cryptogonimidae) from the fork-tailed threadfin bream <Emphasis Type="Italic">Nemipterus furcosus</Emphasis> (Val.) (Perciformes: Nemipteridae) off New Caledonia

Adlardia novaecaledoniae n. g., n. sp. (Digenea: Cryptogonimidae) is described from the fish Nemipterus furcosus (Val.) (Perciformes: Nemipteridae) from off New Caledonia (South Pacific). Adlardia n. g. is distinguished from all other cryptogonimid genera by the combination of an elongate body, the presence of oral spines, intestinal caeca that open via ani at the posterior end of the body, a highly lobed ovary, oblique testes that are located in the mid-hindbody, vitelline follicles that extend from midway between the testes and ovary to midway between the ovary and ventral sucker, and an excretory vesicle that bifurcates dorsal to the ovary and reunites immediately anterior to the pharynx. A. novaecaledoniae n. sp. is the only cryptogonimid that has been reported with an excretory vesicle that reunites anterior to the pharynx. Siphoderina elongata (Gu &; Shen, 1979) Miller &; Cribb, 2008 is transferred to Adlardia as A. elongata (Gu &; Shen, 1979) n. comb. based on morphological and ecological (host group) agreement with A. novaecaledoniae. Bayesian inference analysis of LSU rDNA revealed that A. novaecaledoniae nested well within a clade containing cryptogonimid taxa known almost exclusively from haemulid and lutjanid fishes, suggesting that host-switching between teleosts of the Haemuloidea, Lutjanoidea and Sparoidea may have been common in the evolutionary history of this system.     

<Emphasis Type="Italic">Phuphanochloa,</Emphasis> a new bamboo genus (<Emphasis Type="Italic">Poaceae</Emphasis>: <Emphasis Type="Italic">Bambusoideae</Emphasis>) from Thailand

Summary  A new monotypic bamboo genus Phuphanochloa (Poaceae: Bambusoideae) from north-eastern Thailand is described, together with a new species, P. speciosa.     

Cryptic species of <Emphasis Type="Italic">Euryakaina</Emphasis> n. g. (Digenea: Cryptogonimidae) from sympatric lutjanids in the Indo-West Pacific

A survey of the endohelminth fauna of Indo-West Pacific Lutjanidae (Perciformes) revealed the presence of the species Siphoderina manilensis (Velasquez, 1961) Miller & Cribb, 2008 and S. marina (Hafeezullah & Siddiqi, 1970) Miller & Cribb, 2008 in seven Lutjanus spp. from sites off the Great Barrier Reef, the Maldives, New Caledonia and Ningaloo Reef, Western Australia. A combination of morphological and ribosomal DNA analyses of these cryptogonimids prompted the transfer of these taxa to a new genus, Euryakaina n. g., as E. manilensis n. comb. and E. marina n. comb., based on comparative analysis with other cryptogonimid taxa. Euryakaina n. g. is distinguished from all other cryptogonimid genera by the combination of a fusiform body, the few relatively small, widely spaced oral spines (sometimes absent), a highly lobed ovary, opposite to slightly oblique testes, vitelline follicles that extend from the anterior margin of the testes to slightly posterior to the intestinal bifurcation, and an excretory vesicle that bifurcates dorsal to the ovary and reunites briefly slightly posterior to the intestinal bifurcation. Morphometric analysis of these taxa alone suggests they should be reduced to synonymy, but DNA sequence analyses and ecological niche partitioning provide evidence that they form a cryptic species complex in sympatric lutjanids in the Indo-West Pacific. The secondary structure of the ITS2 rDNA for species of Euryakaina was also modelled and analysed for the presences of compensatory base changes (CBCs) or hemi-CBCs in order to explore the usefulness of these changes as a tool to help elucidate the taxonomy of this complex system. We also report what we interpret here as intraspecific variation in the ITS2 rDNA between individuals of E. manilensis from Lutjanus vitta recovered off the Great Barrier Reef and New Caledonia.     

The Madagascan genus <Emphasis Type="Italic">Vaughania</Emphasis> is reduced to synonymy under <Emphasis Type="Italic">Indigofera</Emphasis> (<Emphasis Type="Italic">Leguminosae-Papilionoideae-Indigofereae</Emphasis>)

Summary  Eleven species comprising the Madagascan genus Vaughania are subsumed within the large pantropical genus Indigofera. Six new combinations are made; the remaining species were originally described in Indigofera.     

<Emphasis Type="Italic">Camellia cattienensis</Emphasis>: a new species of <Emphasis Type="Italic">Camellia</Emphasis> (sect. <Emphasis Type="Italic">Archaecamellia</Emphasis>: Theaceae) from Vietnam

A new species of the genus Camellia L. (Theaceae, Theoideae) is described and illustrated under the name C. cattienensis. This species occurs in the rainforest vegetation of Lam Dong Province, Vietnam. A discussion of the morphological characters distinguishing this new species from related Camellia species is presented. Morphological evidence supports a transitional taxonomic placement in Camellia sect. Archaecamellia Sealy. This placement is justified by C. cattienensis exhibiting some morphological characteristics also found in sects Stereocarpus (Pierre) Sealy and Piquetia (Pierre) Sealy.     

The first report of <Emphasis Type="Italic">Spondias</Emphasis> native to Madagascar: <Emphasis Type="Italic">Spondias tefyi</Emphasis>, sp. nov. (Anacardiaceae)

Spondias represents a genus new to Madagascar’s native flora. Like Campnosperma, it is now known from both American and Asian tropics and Madagascar but not from continental Africa. The new species Spondias tefyi is easily distinguished from all of its Asian congeners by having the stamens shorter than the pistil and fruits brown and lenticellate at maturity (vs. greenish, yellow, orange or red, and relatively smooth). The new species is one of several Anacardiaceae whose fruits are eaten by lemurs in the Analavelona Forest, highlighting the importance of conserving this threatened subhumid forest remnant in southern Madagascar.     

A new species of <Emphasis Type="Italic">Brasiliomyces</Emphasis> (Erysiphaceae) on <Emphasis Type="Italic">Dalbergia cultrata</Emphasis> var. <Emphasis Type="Italic">cultrata</Emphasis> from Thailand

A powdery mildew fungus on leaves of Dalbergia cultrata var. cultrata (Fabaceae) collected at the Queen Sirikit Botanical Garden in northern Thailand is proven to be a new species of the genus Brasiliomyces and is described as B. chiangmaiensis sp. nov. with light and SEM micrographs. Differences in known Brasiliomyces species are discussed, and a key to species of this genus is provided.     

<Emphasis Type="Italic">Proctocaecum gairhei</Emphasis> n. sp. (Digenea: Cryptogonimidae: Acanthostominae) from <Emphasis Type="Italic">Gavialis gangeticus</Emphasis> (Gmelin) in Nepal and a revised cladogram of <Emphasis Type="Italic">Proctocaecum</Emphasis> Baugh, 1957

Proctocaecum gairhei n. sp. is described from the gharial Gavialis gangeticus (Gmelin) in Nepal. The new taxon can be distinguished from all other species of Proctocaecum Baugh, 1957 by the combination of the following morphological characters: a single row of 23 cephalic spines, lateral anal pores opening at uneven levels, a forebody accounting for 16% of the total body length (TBL), an oral to ventral sucker width ratio of 1:0.7, an oral sucker to pharynx width ratio of 1:0.6 and uterine loops that occupy 59-67% of the TBL. While sharing some morphological characteristics with Acanthostomum slusarskii Kalyankar, 1977 from Crocodylus palustris (Lesson) in India, P. gairhei n. sp. is distinguished from the latter by possessing the solid muscular gonotyl diagnostic for Proctocaecum, by the number of cephalic spines, position of the anal pores and egg size. The existing cladogram for Proctocaecum was expanded using the character information of P. gairhei n. sp. The host range of Proctocaecum is now known to include all three families of the order Crocodylia.     

<Emphasis Type="Italic">Atactorhynchus duranguensis</Emphasis> n. sp. (Acanthocephala: Atactorhynchinae) from <Emphasis Type="Italic">Cyprinodon meeki</Emphasis> (Pisces: Cyprinodontidae) near Durango,Mexico

Atactorhynchus duranguensisn. sp. (Acanthocephala: Atactorhynchinae) is described from the intestine of Cyprinodon meeki Miller, an endemic freshwater fish from a far-inland locality of Mexico. Diagnostic features include: body small, stout, ventrally curved; small cylindrical proboscis armed with 16 alternating vertical rows of four or five hooks; anterior two or three hooks conspicuous, stout and larger than other hooks, and have large, rod-shaped roots with a markedly and abruptly enlarged base; three posterior hooks of each row are smaller and rootless; single-walled proboscis receptacle; lemnisci equal in length, elongate and robust; and cement gland syncytial, larger than testis. The new species is smaller than A. verecundus Chandler, 1935, the only previously described species in the genus. The shape of the proboscis of the new species is strikingly different from that of A. verecundus, which is widest at the apex. Likewise, the greatest width of the trunk of the new species is in about the middle, differing from that of A. verecundus where the trunk is widest posteriorly. The new species also can be distinguished from A. verecundus because of its much smaller hook lengths and slightly smaller proboscis. In addition, the proportion of large apical proboscis hooks in relation to the small basal hooks is different: the basal hooks of A. verecundus are about half the size of the anterior hooks and but only about a quarter of the size in A. duranguensis. Unlike A. verecundus, the base of the roots are markedly and abruptly enlarged in the new species. Finally, the eggs of the new species are smaller (23–27 × 8–10 m) than those of A. verecundus (27–30 × 12–13 m).     

<Emphasis Type="Italic">Myrsidea agarwali</Emphasis> sp. n. (Phthiraptera: Menoponidae) from <Emphasis Type="Italic">Garrulax lineatus lineatus</Emphasis> (Passeriformes: Timaliidae)

A new species of chewing louse, Myrsidea agarwali, is described from Garrulax lineatus lineatus (Passeriformes: Timaliidae) from the Rampur district (India). A key is provided for the identification of males and females of Myrsidea from birds of the genus Garrulax.     

Revision of the genus <Emphasis Type="Italic">Poromitra</Emphasis> (Melamphaidae): Part 6. Species of the <Emphasis Type="Italic">P. megalops</Emphasis> group

Species of the genus Poromitra belonging to the P. megalops group are considered on a large collection material. These species are characterized by small sizes (up to 6 cm), oblong body, elongated caudal peduncle, large eyes, four scales on the cheek, bony crests of the anterior margin of the praeoperculum located at a right angle towards each other, and other features. Until recently it was considered that P. megalops (Lütken) has a circumtropical range. This study demonstrated that P. megalops occurs only in the Atlantic Ocean. In the Indian Ocean and the central part of the Pacific Ocean, P. macrophthalma (Gilchrist) dwells. A new species P. jucunda Kotlyar sp. nova is described from the eastern and central parts of the Pacific Ocean. A key to 22 known species of the genus Poromitra is provided at the end of the paper.     

<Emphasis Type="Italic">Strobilomyces verruculosus</Emphasis> sp. nov. from Japan

A new species, Strobilomyces verruculosus, is described and illustrated. It is morphologically distinct from other species of Strobilomyces by having a verruculose pileus with small subpyramidal scales, a long and thick stipe with small warty to appressed scales, subdecurrent tubes, and incompletely reticulate basidiospores. Molecular phylogenetic analyses using the mitochondrial cytochrome oxidase subunit 3 (cox3) gene support that it belongs to the genus Strobilomyces and is highly differentiated from the other members of this genus found in Japan.
