A poecilostome copepod parasitic in a scleractinian coral in the moluccas

Wedanus inconstans, n. gen., n. sp., a lichomolgid copepod living in the polyps of the reef coral Goniopora tenuidens (Quelch), is described from Halmahera in the Moluccas. The genus is apparently related to Xenomolgus Humes & Stock, 1972.     

Pseudoeurotium globosum n. sp., a new ascomycete from Indian soils

Summary The namePseudoeurotium globosum Rai andTewari n. sp. has been given to a fungus isolated from soil collected from the banks of a stream in village Harchandpur, District Rae Bareli, (U.P.) India. This form is distinguished from any other described so far in this genus, in having multisporous asci with large globose ascospores. P.globosum n. sp. inhabits a specialised habitat, and this along with the fact that it was isolated only byWarcup's Soil-plate Method, makes it an ecologically interesting form.     

Morphology and Phylogeny of Two Novel Ciliates,Arcanisutura chongmingensis n. gen., n. sp. and Naxella paralucida n. sp. from Shanghai,China

The morphologies of two novel ciliates, Arcanisutura chongmingensis n. gen., n. sp. and Naxella paralucida n. sp., collected from Shanghai, China, have been investigated using live observation and silver staining methods. Arcanisutura n. gen. can be easily distinguished from related genera by its inconspicuous, oblique anterior suture. Arcanisutura chongmingensis n. sp. is mainly recognized by its elongated body with a tail‐like posterior end, 25–33 somatic kineties, and 4–11 excretory pores. Naxella paralucida n. sp. can be distinguished from its congeners based on its two short nassulid organelles, fusiform trichocysts, 37–49 somatic kineties, and 16 nematodesmal rods. The small‐subunit (SSU) rRNA gene sequences of these two species are presented, revealing the phylogenetic positions of Arcanisutura and Naxella. Phylogenetic analyses show that Arcanisutura forms a sister clade to other synhymeniid genera, namely, Chilodontopsis, Orthodonella, and Zosterodasys; Naxella is most closely related to Nassula spp. and is located within the monophyletic clade of the family Nassulidae.     

Neotropical Monogenoidea. 50. Oviparous gyrodactylids from loricariid and pimelodid catfishes in Brazil, with the proposal of Phanerothecioides n. g., Onychogyrodactylus n. g. and Aglaiogyrodactylus n. g. (Polyonchoinea: Gyrodactylidea)

The diagnosis of Phanerothecium Kritsky & Thatcher, 1977 is amended, and Phanerothecioides n. g., Onychogyrodactylus n. g. and Aglaiogyrodactylus n. g., all comprised of oviparous gyrodactylids (Monogenoidea: Polyonchoinea), are proposed to accommodate 11 of the 15 species (14 new to science) herein described and/or reported from loricariid and pimelodid catfishes (Teleostei: Siluriformes) in Brazil: Phanerothecium harrisi Kritsky & Boeger, 1991, P. spinatoides n. sp. and P. deiropedeum n. sp. all from Hypostomus spp.; P. spinulatum n. sp. from Hypostomus cf. regani; Phanerothecioides agostinhoi n. g., n. sp. (type-species) from Hypostomus spp. and Pseudoplatystoma fasciatum; Onychogyrodactylus sudis n. g., n. sp. (type-species) and O. hydaticus n. sp. both from Ancistrus multispinus; Aglaiogyrodactylus forficulatus n. g., n. sp. (type-species) from Kronichthys lacerta; A. pedunculatus n. sp. from Hisonotus sp.; A. guttus n. sp. from Pseudotothyris obtusa; A. salebrosus n. sp., A. conei n. sp. and A. ctenistus n. sp. all from Pareiorhaphis parmula; and A. calamus n. sp. and A. forficuloides n. sp. both from Schizolecis guntheri. Phanerothecioides n. g. is characterised by oviparous forms lacking superficial and deep haptoral bars and pregermarial vitelline follicles, and by having a conspicuous testis in adult specimens, a syncytial prostatic gland, a reduced copulatory sac and vitelline ducts in the form of an inverted ‘U’. Onychogyrodactylus n. g. is differentiated from all other oviparous gyrodactylid genera by its members having a spine-like accessory sclerite enclosed in a separate pouch associated with the terminal male genitalia. Species of Aglaiogyrodactylus n. g. possess H-shaped vitelline ducts and a complex accessory piece and sclerotised or non-sclerotised male copulatory organ enclosed within the copulatory sac.     

Copepoda associated with the coral Gardineroseris planulata (Dana) on the Great Barrier Reef,northeastern Australia

Three new lichomolgid copepods associated with the scleractinian Gardineroseris planulata (Dana) are described: Sociellus torus, n. gen., n. sp., characterized by a 2-segmented endopod in leg 3 and the lack of an inner seta on the first segment of the endopod in legs 1–3; Odontomolgus pumilus, n. sp., of very small size and having a much elongated free segment in leg 5 of the female; and Paramolgus ampullaceus, n. sp., distinguished by the bottle-shaped genital segment of the female. In addition, the harpacticoid Alteuthellopsis corallina Humes, 1981, is reported from this coral. With the inclusion of 3 species of the poecilostomatoid genus Xarifia already described (Humes, 1985) there are now 7 species of copepods known to be associated with Gardineroseris planulata on the Great Barrier Reef.     

Cetorhinicola n. g., Shirleyrhynchus n. g. and Stragulorhynchus n. g., three new genera of trypanorhynch cestodes from elasmobranchs in Australian waters

Three new genera of trypanorhynch cestodes are described from Australian elasmobranchs: Cetorhinicola acanthocapax n. g., n. sp. from Cetorhinus maximus (Gunner, 1765), with four bothridia joined by avelum, a typical heteroacanthous armature with the ends of the hook rows not meeting on the external surface, and enlarged hooks on the base of the tentacle; Shirleyrhynchus butlerae n. g., n. sp., from Dasyatis fluviorum Ogilby, 1908 and D. sephen (Forsskal, 1775), with four bothridia, typical heteroacanthous armature, enlarged basal hooks, testes in linear rows, and lacking seminal vesicles; Stragulorhynchus orectologi n. g., n. sp., from Orectolobus tentaculatus (Peters, 1864) (type-host), O. maculatus (Bonnaterre, 1788) and O. ornatus (de Vis, 1882), with four bothridia, poeciloacanthous armature, with a band of hooklets on the external surface of the tentacle, external seminal vesicle, hermaphroditic duct, accessory seminal vesicle and post-ovarian testes. None of the new genera is readily accommodated by the existing classification of the Trypanorhyncha: the first two genera are tentatively allocated to the Gilquiniidae and the last to the Gymnorhynchidae.

Trioxys similis n. sp. (Hym. Braconidae,Aphidiinae), eine neue Blattlaus-Schlupfwespe aus Frankreich

Summary In the present paper the author describes the new speciesTrioxys (Trioxys) similis n. sp. (Hymenoptera: Braconidae, Aphidiinae), which has been reared in France from the peach aphid, presumablyMyzus persicae (Sulzer 1776). Considering the fact that this aphid is a world wide distributed pest causing heavy damages by transmission of numerous plant viruses, attention is drawn to use this braconid parasite as a limiting factor in biological control.Trioxys similis n. sp. belongs to the group of species “Trioxys angelicae (Hal. 1833) s. l.”, the biology and taxonomy of which is briefly discussed. The existence of various strains of one parasite species, differing only in their host range or host preference is a major problem both of applied entomology and of insect taxonomy. It is suggested to name these morphologically indistinguishable forms according to terms used in microbiological nomenclature. Finally, the following names have been changed as being homonyms, and new names are proposed instead of them:Aphidius constrictus Benoit 1955=Aphidius benoiti n. n., †Trioxys obscuriformis Quilis 1940=†Trioxys fossilis n. n.

Résumé Sonderia labiata n. sp., se distingue de Pespèce voisine S. vorax Kahl par ses caractères écologiques de Cilié marin psammobie et facultativement sédentaire; par une asymétrie moins marquée que chez les autres espèces du genre; par la presence de corps de réserve polysaccharidiques de forme lamellaire.     

Copepoda (cyclopoida,Lichomolgidae) associated with the Alcyonacean Nephthea in the moluccas

In the Moluccas five lichomolgid copepods are associated with soft corals of the genus Nephthea. Paramolgus nephtheanus, n. sp., from Nephthea chabrolii, Nephthea sphaerophora, Nephthea cupressiformis, Nephthea albida, and Nephthea galbuloides, Paramolgus prominulus, n. sp., from N. sphaerophora, N. cupressiformis, and N. albida, and Paramolgus accinctus, n. sp., from N. sphaerophora, N. cupressiformis, N. albida, and N. galbuloides are distinguished from conspecifics by combinations of several characters. These include, among others, the length of the caudal ramus, the form of the female genital segment, and the shape of leg 5 in the female. Mecra ellipsaria, n. gen., n. sp., from N. sphaerophora has only two setae on the fourth segment of the first antenna, the formula II, 2 on the third endopod segment of leg 3, and five aesthetes on the second segment of the first antenna of the male. In Metaxymolgus lumarius, n. sp., from N. galbuloides and N. cupressiformis, the two claws on the second antenna are longer than the fourth second antennal segment and the proximal inner expansion of leg 5 in the female has a thorn-like process. Metaxymolgus aculeatus (Humes & Ho, 1968) occurs on N. chabrolii, N. sphaerophora, N. cupressiformis, N. albida, and N. galbuloides.     

Pnoepyga immaculata n. sp., eine neue bodenbewohnende Timalie aus dem Nepal-Himalaya

Zusammenfassung Pnoepyga immaculata n. sp. lebt im Areal der beiden anderenPnoepyga-Artenalbiventer (Hodgson 1837) undpusilla Hodgson 1845 und wurde durch ihren markant abweichenden Territorialgesang entdeckt. Sie besitzt eine kurze silberhelle Strophe aus kurzen, in gleichmäßigen Abständen gereihten Pfiff-Elementen, die in der Frequenz leicht abfällt. Neben der Stimme liegen die wesentlichen diagnostischen Merkmale nach jetzigem Kenntnisstand gegenüber sympatrischenalbiventer in wenig größerem Schnabel, der Fleckenlosigkeit von Oberseite, Kopf und Flügeldecken, gegenüberpusilla in den größeren Körperabmessungen, gegenüber sympatrischenalbiventer undpusilla im schwachen grünlichen Schimmer der Oberseite und in der länglichen Schuppung der Unterseite. Es bestehen keine Proportionsunterschiede zwischenimmaculata undalbiventer/pusilla einerseits wie auch nicht zwischen diesen beiden andererseits. Bis jetzt wurden 4 Belegstücke (SammlungenKoelz, Diesselhorst, Martens) und eine durch Bandaufnahme gesicherte Beobachtung zwischen Dhaulagiri in Mittelwest-Nepal bis nahe der Ost-Grenze Nepals bekannt.P. immaculata lebt zur Brutzeit in enger Nachbarschaft mitP. albiventer undP. pusilla, ist jedoch vonalbiventer vertikal getrennt bei nachgewiesenem Kontakt, vonpusilla durch Bevorzugung trockeneren Waldunterwuchses abseits von Bächen. Schon jetzt mußimmaculata als gefährdete Art eingestuft werden, da Waldvegetation in der zur Brutzeit bevorzugten Höhenstufe zwischen 2100 und 3100 m in Nepal weitgehend vernichtet worden ist.

Pnoepyga immaculata n. sp., a new ground living wren-babbler from the Nepal Himalayas (Timaliidae)

Summary P. immaculata n. sp. was discovered by its voice which strongly differs from the two other sympatric species,albiventer (Hodgson 1837) andpusilla Hodgson 1845. As a territorial song, it displays a silvery strophe arranged of short, more or less regularly spaced whistling notes (fig. 7a–d), slightly descending in pitch. The strophe is about 2 s long. Besides the distinct voice, the essential diagnostic characters in comparison toP. albiventer are the slightly larger bill, plain head, upper side and wing coverts (fig. 1a–d, 2, 4a–d), in comparison topusilla the larger body size (fig. 1i–m), in comparison to sympatricalbiventer andpusilla the slightly olive tinge of the upper side (against warm dark brown in both others, fig. 1e–m), and the more longish scaly feathers of the lower side (against stout scaly appearance in both others, fig. 1 a–d). These characters hold true at least in Central and Eastern Himalayan populations of the respective species. There do not exist proportional differences in the relations of any part of the body betweenimmaculata andpusilla and not between the latter ones as well. Heretofore, 4 museum specimens are known (Koelz Coll.,Diesselhorst Coll.,Martens Coll.) from West-central (Thakkhola, type locality) and East Nepal (Ting Sang La), 3 of them from the presumed breeding grounds (2100–3100 m), one from the winter quarters in the Terai lowlands. A field observation close to the Darjeeling border in far East Nepal is verified by a tape-recording.P. immaculata embarasses the biologist and systematist because it lives in close neighbourhood of the similar speciesalbiventer andpusilla. It must have been overlooked by its apparent scarcity and overall similarity to both other species of the genus. Slight ecological differences rather correspond to the vertical distribution ofalbiventer, which populates a higher forest belt. But both have already been found on territory at close range.P. pusilla inhabits different microbiotopes, especially the close proximity of running water in the same altitudinal belt asimmaculata. When discovered,P. immaculata is to be classified already as an endangered species. Forest vegetation of its preferred altitude is already greatly reduced in the Central and Eastern Nepal Himalayas. To get a more detailed information on its general distribution and biology in order to quickly arrange protected areas and thus to guarantee the survival ofP. immaculata, should be the urgent next step.

Cynoglossopsis somaliensis H. Riedl, sp. nov., is described as a new species of the hitherto monotypic genusCynoglossopsis Brand which is closest related toCynoglossum L. but has to be included inBoraginoideae-Eritrichieae from the way the nutlets are attached to the gynobasis.

     

Two New Diophrys‐Like Genera and Their Type Species,Apodiophrys ovalis n. g., n. sp. and Heterodiophrys zhui n. g., n. sp. (Ciliophora: Euplotida), with Notes on Their Molecular Phylogeny

ABSTRACT. Based on both morphological and molecular information, two new euplotid genera Apodiophrys n. g. and Heterodiophrys n. g. are described in the present paper. Apodiophrys n. g. is defined as sculptured Diophryinae with bipartite adoral zone; frontoventral cirri arranged in Diophrys‐pattern; marginal cirri located in two clearly separated groups. Heterodiophrys n. g. is recognizable by the combination of Diophrys‐like frontoventral cirri and the unique structure of several marginal cirri that are arranged in a long row. The type species for both new genera, Apodiophrys ovalis n. sp. and Heterodiophrys zhui n. sp., collected from southern China sea, are described. The small subunit rRNA (SSU rRNA) gene sequences for both new taxa are determined. Phylogenetic analyses based on these data indicate that Apodiophrys is most closely related to Paradiophrys, which then clusters with Uronychia species. Thus, Apodiophrys–Paradiophrys is separated from other typical Diophrys‐like genera in the SSU rRNA gene trees. The new genus Heterodiophrys is basal to the sister group of Diophrys–Diophryopsis, hence belongs to the “core”Diophrys‐complex.     

Schizosaccharomyces malidevorans sp.n., a yeast decomposing L-malic acid

A new yeastSchizosaccharomyces malidevorans sp.n. is described. It resemblesSchizosaccharomyces pombe but differs from it in appearance of the spores and inability to ferment maltose. It decomposesl-malic acid completely in all grape juice and synthetic media tested, but not thed-isomer. During fermentation a copious evolution of hydrogen sulphide occurs.     

Coulonia parva n. sp., a new species of Astropectinidae (Asteroidea; Echinodermata) from the Santonian (Upper Cretaceous) of Sierra de Montsech (southern Pyrenees, Spain)

A new astropectinid sea star,Coulonia parva n. sp., is described from the Santonian of the Sierra de Montsech, northern Spain. The single specimen shows part of a rather weathered ventral side. It is characterized by comparatively long arms (R/r approx. 3/1), with one row of actinals reaching far into the arms; inferomarginals on the interbrachial arc have deep fasciolar grooves that are less developed on the arms; there are no larger spines on adambulacrals and probably also on inferomarginals. Based on presence of deep marginal fascioles,C. parva n. sp. is inferred to have shared the capability for self-burial with the relatedC. platyspina Hess &Blake.      

Favositidae (Tabulata) from Emsian to Middle Devonian limestones of the Tamworth Group (N.S.W., Australia)

Several different species and species groups of the familiy Favositidae from the Emsian and Middle Devonian limestones of the Tamworth Group (N.S.W., Australia) are described. The Emsian Sulcor Limestone Member yieldedFavosites sp. aff.F. basalticus (Goldfuss, 1826),Favosites sp. aff.F. salebrosus Etheridge, 1899,Favosites stellaris Chernyshev, 1937,Squameofavosites nitidus (Chapman, 1914),Sq. bryani (Jones, 1937),Pachyfavosites rariporosus Dubatolov, 1963, andP. tumulosus Yanet, 1965. The Middle Devonian Moore Creek Limestone Member yieldedFavosites ex gr.goldfussi D’Orbigny, 1850, exclusively. In the Emsian limestones occur favositids in a wide array of different facies, with most being found in stratified biostromes and in bedded nodular limestones. In the Middle Devonian most favositids are found in nodular and lumpy limestones which occur at the base and at the top of some successions
