Rhodobryum commersoni(Schwaegr.) Par. and R. aubertii (Schwaegr.) Thér. in South India.

Abstract

A new species Tristichella dimorpha is described and illustrated and a comparison made with the two other species in the genus, T. spiculifera and T. glabrescens, and with Clastobryella cuculligera to which it appears to be closely related, particularly in sporophytic characters.     

Revision of the genera Nemotha Wood-Mason, 1884 and Tricondylomimus Chopard, 1930 stat. rev., with description of a new species (Dictyoptera: Mantodea)

The oriental species previously included in the rarely collected genus Nemotha Wood-Mason, 1884 (Mantodea: Iridopterygidae) are revised. N. coomani (Chopard, 1930) and N. mirabilis Beier, 1933 strongly differ from the type species N. metallica (Westwood, 1845) by family-level morphological features, but share a unique type of forefemoral armament with the genera Hapalopeza Stål, 1877 and Amantis Giglio-Tos, 1915, suggesting Nemotha is of a polyphyletic nature. The genus Tricondylomimus Chopard, 1930 is resurrected from synonymy to accommodate T. coomani, T. mirabilis n. comb. and the species which is newly described in this article, T. intermedius n. sp. The monotypic genus Pseudogousa Tinkham, 1937 and its species P. sinensis Tinkham, 1937 are synonymized with Tricondylomimus and T. mirabilis, respectively. The genus Tricondylomimus is placed in Iridopterygidae, while Nemotha is transferred to Hymenopodidae: Anaxarchini.

INTRA- AND INTERSPECIFIC DIFFERENCES IN AGONISTIC VOCALIZATION IN CROAKING GOURAMIS (GENUS: TRICHOPSIS,ANABANTOIDEI, TELEOSTEI)

ABSTRACT

In this study a detailed analysis of acoustical parameters of sounds produced by male Trichopsis vittatus, T. schalleri and T. pumilus during agonistic behaviour is reported. The calls consist of croaks which are composed of double pulses generated by modified pectoral fins. Calls of the three species are different in main frequency, number of double pulses within a croak and double pulse period. Croaks are uttered in series only in T. vittatus. Sound pressure levels are highest in T. pumilus, the smallest species. Amplitude of individual pulses of a double pulse are similar in T. pumilus and T. schalleri. Main frequency is negatively correlated with body mass in all species, but there is no correlation between sound pressure level and body mass. Differences in the calls of the three species suggest that T. schalleri is a distinct species. Furthermore, results indicate spectral characteristics and sound intensity could be of biological importance in fish.

Two new species of Tupaiostrongylus Dunn, 1963 (Nematoda: Molineidae) from a tree shrew (Tupaia tana) of Indonesia

Summary Tupaiostrongylus major n. sp. and T. minor n. sp. which are co-parasites in Tupaia tana from Indonesia, are differentiated from the type (and only other) species, T. liei Dunn, 1963, by the presence of six and not five tubercles on the female tail and by the morphology of the distal points of the spicules. Two new species are distinguished from each other by body size, number of cuticular crests of the synlophe, and the shape of the distal points of the spicules.

Résumé Deux nouvelles espèces du genre Tupaiostrongylus Dunn, 1953 (Nematoda: Molineidae) parasites de Tupaia tana en Indonésie Tupaiostrongylus major n. sp. et T. minor n. sp. sont coparasites de Tupaia tana en Indonésie.Les deux espèces se différencient de l'espèce type unique du genre T. liei Dunn, 1963 par la présence de 6 et non 5 tubercules sur la queue de la femelle. De plus, chez T. liei, seule la pointe interne des spicules est recourbée. Chez les 2 autres espèces, les 2 pointes de chaque spicule sont recourbées. Elles sont dirigées dans le même sens chez T. major et en sens inverse chez T. minor. Enfin, T. major est nettement plus grand et plus large que T. minor, alors que le nombre de crêtes cuticulaires est plus faible. ac]19810407

     

Studies in African thelephoroid fungi: 1. <Emphasis Type="Italic">Tomentella capitata</Emphasis> and <Emphasis Type="Italic">Tomentella brunneocystidia</Emphasis>, two new species from Benin (West Africa) with capitate cystidia

This paper presents Tomentella capitata and Tomentella brunneocystidia as new species based on molecular data and anatomical features. Both T. capitata and T. brunneocystidia form sister species with Tomentella pilosa. All three taxa are well supported by bootstrap values. Anatomically, T. capitata and T. brunneocystidia are very close and are similar in shape, size, ornamentation of basidiospores, and size and colour of subicular hyphae. Monomitic rhizomorphs sometimes covered by irregularly shaped thin hyphae are present in both species. Shape and pigmentation of the cystidia are the most discriminating features between T. capitata and T. brunneocystidia. The cystidia of T. capitata are maximum 35 μm long, show a distinctive globose apex and are sometimes covered with dark brown pigmentation and/or encrustation, whereas cystidia of T. brunneocystidia are bigger, up to 55 μm long, with a sub-capitate shape and dark blue to dark green contents all over their length. The differences to species, already described as having capitate and clavate cystidia, are discussed. A key for the identification of cystidioid Tomentella species is given. Taxonomical novelties: Tomentella capitata Yorou & Agerer, Tomentella brunneocystidia Yorou & Agerer.     

Assessing ectomycorrhizal fungal spore banks of truffle producing soils with pecan seedling trap-plants

Background and Aims

Recently, the truffle species Tuber lyonii Butters was found to be dominant in ectomycorrhizal (EcM) fungal communities of cultivated pecan (Carya illinoinensis (Wangenh.) K. Koch). Many truffle fungi exhibit the trait of effectively colonizing plant roots via spores. We hypothesized that T. lyonii would be well represented in the spore bank of pecan orchard soils where it is found.

Methods

We used axenically-grown pecan seedlings as trap-plants to bait for EcM associates in soils collected beneath truffle-producing pecan trees. EcM fungi on seedlings were characterized through rDNA sequencing and were compared to EcM communities of adult trees in these orchards.

Results

Tuber lyonii mycorrhizas were well formed on seedlings inoculated with truffle spores, but were limited to just a few of the trap-plants grown in field soils. We compared EcM communities of adult pecan orchard trees to those on trap-plants and found distinct communities on each, with a high degree of similarity at the ordinal but not species level.

Conclusions

Although species of Pezizales are abundant in pecan EcM communities and as propagules in their soil spore banks, only a low level of T. lyonii was detected in soil spore banks beneath orchard trees naturally colonized by T. lyonii. Other factors including land-use history or orchard management may better explain this truffle species presence and abundance in pecan EcM communities.

     

New species of Hypolytrum Rich. (Cyperaceae) from the Neotropics

Koyama, are species with pseudopetioles and colored leaves, and endemic to the rain forest of southeastern Brazil.Hypolytrum bahiense (sect.Hypolytrum), a species with a lax synflorescence and two, free and lightly scabridulous floral bracts, is endemic to the rain forest of southeastern Bahia, Brazil.Hypolytrum leptocalamum (sect.Hypolytrum), a species with lax synflorescence and spike ellipsoid to cylindrical, is restricted to area of tepuis in the Guayana Highland (Brazil, Guyana, and Venezuela).Hypolytrum paraense (sect.Hypolytrum), a species with three, partly connate and densely scabridulous floral bracts, is restricted to the rain forest of the Amazon Basin, in the state of Pará, Brazil.     

Synopsis of the tribe Bocageeae (Annonaceae), with revisions of Cardiopetalum,Froesiodendron, Trigynaea,Bocagea, and Hornschuchia

The tribal name Bocageeae Endlicher is reestablished and the tribe is circumscribed on the basis of solitary internodal ebracteate pedicels that are articulated at the base, and pollen shed in polyads of eight or more grains. Septate anther locules, large pollen size, and seed appendages are prevalent in the tribe. Intectate pollen with free-standing columellae, rare in Annonaceae, occurs not only in the genusTrigynaea but also in some species ofBocagea andHornschuchia. As defined here, the Bocageeae include seven neotropical genera:Cymbopetalum, Porcelia, Bocagea, Cardiopetalum, Froesiodendron, Hornschuchia, andTrigynaea. The latter five genera are revised and the treatments include ten new species:Cardiopetalum plicatum, Froesiodendron urceocalyx, Hornschuchia lianarum, H. santosii, H. leptandra, Trigynaea cinnamomea, T. lanceipetala, T. triplinervis, T. lagaropoda, andT. axilliflora, all from tropical South America. A new combination,Froesiodendron longicuspe, changes the rank of that taxon from subspecies to species.Cardiopetalum surinamense is removed fromFroesiodendron and reassigned toCardiopetalum on the basis of its connate petals, dehiscent monocarps, and seeds with bilobed arils. A cladogram provides an explicit hypothesis of intergeneric relationships in the tribe. The new combinationOnychopetalum periquino, based onTrigynaea periquino, is made.

Genetic structure of mosses Pleurozium schreberi (Willd. ex Brid.) Mitt. and Racomitrium lanuginosum (Hedw.) Brid. along altitude gradients in Hokkaido,Japan

Abstract

The families Pterigynandraceae and Rigodiaceae are reviewed for Africa with reference to the collections made by the BBS Expedition to Mt Mulanje, Malawi in 1991. The single African species of Rigodium (Rigodiaceae) is reported to be quite frequent on Mt Mulanje, and three of the four species of Trachyphyllum (Pterigynandraceae) found in Africa (T. gastrodes, T. dusenii and T. inflexum) are reported, the latter two for the first time from Malawi. On present limited evidence, Malawi seems to be a centre of diversity of the genus.
