Description of six new species of the genus Cornudiscoides Kulkarni, 1969 (Monogenoidea: Dactylogyridae) from two catfish, Mystus, Scopoli, 1777 and Sperata Holly, 1939, with a note on its biodiversity

The genus Cornudisoides Kulkarni, 1969 is a specialist monogenoid reported from two fish host, Mystus and Sperata. Despite their ecological importance, Cornudiscoides diversity remains unexplored, and the taxonomic description of nominal species is inadequate. The present study was performed to chart the biodiversity of the genus Cornudiscoides and defined the characters to identify their species quickly and efficiently using unambiguous characters. Examination of fish hosts collected from different localities of Uttar Pradesh revealed 12 known and 6 new species of Cornudiscoides. Since the original description of known species lacked some salient features, the present study has redescribed them and added new host records. The new species are described: C. tripathii sp. nov., C. lucknowensis sp. nov., C. speratai sp. nov., C. indicus sp. nov., C. kulkarnii sp. nov. and C. falcatum sp. nov. They have distinct copulatory complexes and vaginal armatures. A detail of the species diversity of Cornudisoides, their type host, new host record type locality, additional localities and major distinguishable characters would be helpful to understand the diversity of these parasites.

<I>Athelopsis</I> <I>parvispora</I> (<I>Basidiomycetes</I>), a new species from India

A new corticioid species, Athelopsis parvispora, is described from Manali hills in Himachal Pradesh. While conducting the fungal forays in the oak forest in Gulaba area of Manali hills district Kullu of Himachal Pradesh, India, Avneet and Dhingra collected a corticioid specimen on a stump of Quercus incana. After detailed macroscopic and microscopic comparisons with descriptions of known species of genus Athelopsis (Julich 1971, Eriksson & Ryvarden 1973, Hjortstam 1991, Kotiranta & Saarenoksa 2005), it was found to be close to Athelopsis subinconspicua (Litsch.) Julich . Characters in common were thin, pellicular basidiocarps with smooth hymenial surface and clavate, basally stalked basidia, but the basidiospores in the newly described species differed in being narrowly ellipsoid and smaller (4.3-4.7 × 1.5-1.9 µm) compared to the more broadly ellipsoid and larger (6.5-8 × 4-4.5 µm) spores in A. subinconspicua. This suggests that this new finding represents a species of its own. Athelopsis parvispora Avneet P. Singh, Dhingra & J. Kaur, sp. nov . Figs 1-4 MycoBank MB517012 Basidiocarpum resupinatum, adnatum, effusum, ad 160 µm crassum, pelliculosum; hymenium laevigatum flavescens; systema hyphale monomiticum; hyphae ad 3.1 µm latae, nodoso-septatae; hyphae basales crassitunicatae, incrustatae; subhymenial hyphae tenuitunicatae, non incrustae; basidia 10.9-16 × 3.0-3.9 µm, clavata, stipitata, 4- sterigmata, ad basin fibuligera; basidiosporae 4.3-4.7 × 1.5-1.9 µm, auguste ellipsoideae, tenuitunicatae.

Trophobiosis between a blattellid cockroach (Macrophyllodromia spp.) and fulgorids (Enchophora and Copidocephala spp.) in Costa Rica

Three instances were observed in Costa Rica, of an adult cockroach feeding on or palpating the waxy material secreted on the tegmina of a fulgorid; in one instance, the cockroach was a female Macrophyllodromia sp. and the homopteran a fulgorid, Enchophora sanguinea. In another, the cockroach was Macrophyllodromia maximiliani and the fulgorid was Copidocephala guttata. These are the first observations of trophobiosis in a cockroach. Brief descriptions of known species of Macrophyllodromia, and the male genitalia of 2 species are given.

Tropical mangrove leaf litter fungi in Singapore with an emphasis on Halophytophthora

A study on the mangrove leaf litter fungi of two tropical mangroves in Singapore was carried out. Five Halophytophthora species and four isolates which did not fit the descriptions of known species were isolated from leaves of Avicennia alba, A. rumphiana, Rhizophora apiculata and R. mucronata. Halophytophthora exoprolifera, H. kandeliae, H. operculata, H. spinosa var. lobata and H. vesicula are new records for Singapore; the first three also being new records for tropical mangroves. The isolate of H. exoprolifera sporulated at 28 °C and may be a tropical strain. H. operculata is reported for the first time outside of Australia. The results of this study contribute to the little known distribution of the Halophytophthora in the Indian Pacific region. Thirteen deuteromycetes were also isolated from the mangrove leaf litter and represented both phylloplane fungi as well as possible marine fungi.

Revision of the stonefly family eustheniidae (Plecoptera), with emphasis on the fauna of the Australian region

The revision includes diagnoses of the family and its subfamilies. Keys to genera and species are provided. Descriptions of known species are supplemented or corrected. Several new synonymies are established and some new species are described. The majority of species in the Australian Region are illustrated, and detailed faunistical data are also presented. The following taxa are recognized: Eustheniidae Tillyard; Eustheniinae Tillyard (= Thaumatoperlinae Tillyard): Neuroperlopsis lilies (N. patris Illies), Thaumatoperla Tillyard (T. robusta Tillyard; T. flaveola Burns & Neboiss; T. alpina Burns & Neboiss; T. timmsi nov. spec.), Eusthenia Gray (=Eustheniopsis Tillyard, nov. syn.) (E. costalis Banks = E. purpurescens Tillyard, nov. syn. . = E. purpurescens extensa Tillyard, nov. syn.; E. lacustris Tillyard = E. spectabilis eulegnica Tillyard, nov. syn.; E. spectabilis Gray = E. lunulata Tillyard, nov. syn., = E. reticulata Samal—not Tillyard! , nov. syn.; E. reticulata (Tillyard), nov. comb.; E. venosa (Ti...

The Ascidians Trididemnum Alleni and Distaplia Garstangi, New Species from the Plymouth Area

Two ascidians have been collected in the region of Plymouth that do not fit the descriptions of known species sufficiently well to be identified with them. They are species of Trididemnum and Distaplia.These genera are represented in waters around the British Isles only by Trididemnum tenerum (Verrill) and Distaplia rosea Delia Valle. If Trididemnum niveum should be a valid species and not a synonym for T. tenerum as considered by Hartmeyer (1924), it also is probably present. Accordingly, any species that cannot be identified with these forms must either be new, or must represent geographical extensions of species not previously recorded. In this last respect, the possibility of the Mediterranean Distaplia magnilarva reaching the western Channel must be considered. As the following discussions indicate, the conclusions are that the two forms described here cannot be properly identified with any of the above and are to be treated as new species.Trididemnum alleni n.sp. is named after the late Dr E. J. Allen, so long the inspiring and humane director of the Plymouth Laboratory, while Distaplia garstangi n.sp. is so named as a small tribute to Professor Walter Garstang for his pioneering interest in the ascidians of Plymouth waters.Trididemnum Alleni sp.nov.Colonies are usually small, less than a centimetre in greatest length, and about 3 mm. thick. They are brilliantly white, an appearance retained even in preserved specimens of long standing. The surface is uneven. They are commonly attached to Eunicella and larger hydroids such as Antennularia at depths of from 10 to 30 m., and have been recorded with certainty only from the Plymouth area of the English Channel.
