An investigation concerning two alleged species of Dracontomelon Bl., Anacardiaceae

Abstract

Three new species of this genus were described in 1961 and 1962 by M. L. Tardieu-Blot. In their original account, Evrard and Tardieu cited five specimens of the first species, D. laoticum, which were collected from Laos and South Vietnam. Of the other two species, D. petelotii Tard. from North Vietnam and D. schmidii Tard. from Cochin-China, only one specimen of each is cited. The present investigation indicates that two of these species do not belong to the genus Dracontomelon Bl.     

The Mollissima subgroup of fannia Desvoidy,with the description of a new species from Burma and a revised key to species (Diptera: Muscidae)

Synopsis

A comparison of the type-species of the genus Coelomyia Haliday (C. mollissima Haliday) with that of the genus Fannia Desvoidy (F. scalaris Fabricius) shows that these two genera cannot be maintained as equivalent phylogenetie taxa. Coelomyia is synonymized with Fannia and its species placed in Fannia, four new combinations thus being established. The mollissima subgroup is defined and its affinities shown, a new species is described, and a revised key to species is given.     

A survey of the genus Stegana Meigen from southern Japan (Diptera,Drosophilidae), with descriptions of three new species

Nine species of genus Stegana from southern Japan, including three new species, S. (Oxyphortica) nigripennis Hendel, S. (Steganina) ctenaria Nishiharu, S. (Steganina) izu Sidorenko, S.

(Steganina) biprotrusa sp. nov. and S. (Steganina) bacilla sp. nov. are surveyed and described with designation of a new synonym S. (Steganina) maymyo Sidorenko. A key to all species of genus Stegana from southern Japan is provided.     

LIX.—Freshwater Copepoda and hydrogen ion concentration

Summary

The genus Tristria is redescribed and defined, and a key is given to the known genera of the subfamily Tropidopolinae. A key to the nine species included in the genus is also provided, and all the species are diagnosed and notes given on their distribution.     

Redescriptions of two termites from Burmese amber

Summary

Danothrips Bhatti 1971 is revised and its relations with Chaetanaphothrips Priesner are discussed. The genus is redefined in view of the increased number of species within the genus, and a key is provided to distinguish the species. Six species are included: setifer Bhatti 1971 theifolii (Karny 1921), theivorus (Karny 1921), trifasciatus Sakimura 1975, and two new species, alis and moundi. The range of distribution of trifasciatus, originally described from Hawaii, is considerably extended by its new findings from the Lesser Antilles (St. Vincent Island) and Indonesia (Andalas).     

A revision of the genus Heliconema Travassos, 1919, Physalopteridae (Nematoda)

Summary

It is accepted that the genus Ortleppina Schulz, 1927, is a synonym of the genus Heliconema Travassos, 1919.

Five valid species of Heliconema are recognized: H. heliconema, H. ahiri, H. baylisi, H. brevispiculum and H. longissima.

A new species, H. baylisi is described, and H. heliconema, H. brevispiculum and H. longissima are redescribed.     

A new genus and species of Ricaniidae from Palaeocene deposits in North Dakota

Summary

A new genus and species, Cotradechites lithinus Fennah, are proposed for a fossil tegmen of a Ricaniid (Homoptera : Fulgoroidea) collected in clay deposits of Latest Palaeocene age near Dickinson, North Dakota. The new genus is considered to be most nearly related to the modern tropical American genera Cotrades and Semestra.     

On the new goby,Ctenogobius veliensis (Teleostei: Gobiidae) from the South-West coast of India

Summary

Ctenogobius veliensis, a new species of gobiid fish is described from the South-West coast of India. The characters of the fish conform to those of the genus Ctenogobius Gill but differ markedly from those of other recorded species of the genus. Apart from the usual, external morphological, morphometric and metistic characters, several other features such as the cephalic-lateralis system, skeletal features and morphology of the alimentary canal are also studied and have been found to be of significance for identifying the species. The fish shows distinct sexual dimorphism in many features.     

LVII.—A new species of Lyriocrinus from the Wenlock Limestone

Summary

Analysis of variation in the anal inter-radius of the American species Lyriocrinus melissa (Hall) supports the assignment of the new English species described to the genus Lyriocrinus.     

A new hyaliodine genus for Megacoelum nigroscutellatum Distant with new combinations and tribal reassignment for some other species of Miridae (Heteroptera)

Summary

A new genus is erected for Megacoelum nigroscutellatum Distant in the Hyaliodinae as opposed to the Mirinae where the species was originally described. Two species previously described in the genus, Araspus Distant, viz. A. scutellaris Poppius and A. bicolor Poppius, are considered not congeneric with the genotype of the genus and are therefore transferred tentatively to Imogen Kirkaldy in the Saturniomirini. The genus Attractotomelus recently erected by Linnavuori (1975) for Attractotomus serosus Odhiambo is synonymized with Millermiris Carvalho while the transfer of the latter to the Phylinae by Schuh (1974) is confirmed. Proboscidocoris nitidus Odhiambo is transferred to Polymerus Hahn while Polymerus capitatus (Distant) is transferred to Proboscidocoris Reuter and P. antennatus (Distant) to Charagochilus Fieber.     

Zoogeography and evolutionary ecology of the genus Platorchestia (Crustacea,Amphipoda, Talitridae)

ABSTRACT

Species of the genus Platorchestia occur both in the northern hemisphere (18 species) and southern hemisphere (three species plus a synanthropically introduced species in South America and South Africa). The greater number of endemic Platorchestia species in the North Pacific Ocean suggests that it could be the epicentre of evolution for this genus. North-western Pacific Platorchestia includes 15 species which occupy five ecotopes: wrack (seven species), terrestrial leaf litter (five species), freshwater (one species), marsh (one species) and tentatively present in caves (one species). North-eastern Pacific Platorchestia includes only one putative driftwood specialist, with no other species found in North American coastal habitats. This compares with three good endemic Platorchestia species (plus two putative additional species) and only two ecotopes: wrack (three species) and freshwater (two species) from the North Atlantic Ocean, inclusive of the Gulf of Mexico and Mediterranean Sea. Insufficient data is available to consider Platorchestia zoogeography for the Arabian Sea and Bay of Bengal. Synanthropic dispersal involving Platorchestia in Polynesian outrigger canoes, or in solid ballast carried in the holds of wooden sailing ships has been identified as a potential complicating factor in the zoogeography of this genus. Platorchestia is proposed to have arisen on Laurasia and is therefore basically a northern hemisphere genus. Questions concerning Platorchestia zoogeography and evolutionary ecology are posed and two methods (more intensive field sampling and molecular genetics) are suggested to be the way to solve them.     

I.—Notes on the Natural History of East Finmark

Synopsis

A new species of Argyrophylax, parasitic on the Banana Scab-Moth Nacoleia octasema Meyrick, is described and the Oriental and Australasian species of this genus are reviewed; a key is given for their identification. Six species and a subspecies hitherto placed in other genera are here assigned to Argyrophylax, and seven new combinations are established; two specific names are newly placed in synonymy.     

The Conidae (Mollusca: Gastropoda) of India

Summary

The polyp and immature medusa stages of Cladonema californicum Hyman, are described. The life cycle of the species was observed in the laboratory and took about 47 days to complete under laboratory conditions. Field collections from Bodega Harbor indicated that the medusae and reproductive polyp are present all year. A review of the taxonomy of the genus reveals that there are possibly only two valid species of Cladonema if one bases species separation on the medusa alone: C. radiatum and its ‘varieties’, and C. californicum. Additional work is needed to elucidate the relationships among the described varieties of the medusae of C. radiatum and the morphology of their respective polyps before further revision of the genus can be attempted.     

LXXXI.—Notes on the classification of the African monkeys in the genus Cercopithecus,erxleben
