Four new freshwater gobies of the genus Rhinogobius (Teleostei: Gobiidae) from northern Vietnam

Four new freshwater gobies of the genus Rhinogobius Gill, were collected from the river running into the Gulf of Tonkin in northern Vietnam. They are Rhinogobius boa new species, Rhinogobius variolatus new species, Rhinogobius virgigena new species and Rhinogobius sulcatus new species. These four new species can be distinguished from other congeneric species by a combination of characters such as the meristic features, shape of body, shape of first dorsal fin and coloration pattern.     

Discovery of the freshwater genus Sicyopus (Teleostei: Gobioidei: Sicydiinae) in Madagascar,with a description of a new species and comments on regional dispersal

In the Indo-Pacific area, insular rivers are mainly colonized by gobiids of the Sicydiinae subfamily. These species spawn in freshwater, where the free embryos drift downstream to the sea before returning to rivers to reproduce; they are amphidromous. These gobies are the greatest contributors to the fish diversity and have the highest levels of endemism. Among the nine known genera of Sicydiinae, only two have been found in the West Indian Ocean, and only one (Sicyopterus) is known from Madagascar. Recently, two surveys discovered a new species in the genus Sicyopus. Sicyopus lord sp. nov. differs from other species by a combination of characters that includes a particular colour pattern, similar in both sexes; more scales than its congeners in lateral series (35–43), transverse back series (12–18) and a shorter caudal fin length in male fish. This paper describes the new species and discusses the presence of this genus in Madagascar.

Re-evaluation of the fossil Phoridae (Diptera)

I re-evaluated the known fossil phorids after re-examining much of the Baltic amber and Dominican amber fauna. Many extant genera reported from Eocene Chinese and Eocene/Oligocene Baltic amber are actually not present; instead there are representatives of relatively primitive stem-group taxa. A new genus and species of fossil phorid, Limulomyia tyche, based on a male and a limuloid female, is described from Baltic amber. Some changes in the taxonomy of amber phorids are proposed: Pseudometopina Disney is synonymized with Metopina Schmitz (new synonymy), Diplonevra meunieri Brues is transferred to the genus Godavaria Brown (new combination), Protophorites fimbriatus Brues is considered a junior subjective synonym of Protoplatyphora tertiaria Brues (new synonymy) and Phalacrotophora tertiara Statz is transferred to the genus Gymnophora (new combination). The oldest confirmed dates for extant phorid genera are given.     

Gobiid fishes from the Cape Verde Islands,including two new species of Gobius (Teleostei: Gobioidei)

Ten species of gobiid fishes (Teleostei: Gobioidei) now listed from the Cape Verde islands fall into several zoogeographical categories, including tropical West African Bathygobius casamancus, Mauligobius nigri, Porogobius schlegelii (unconfirmed) and Vanneaugobius canariensis, tropical amphiatlantic B. soporator and Gnatholepis thompsoni, and Canarian Didogobius kochi. Two new species of the eastern Atlantic, predominantly temperate genus Gobius are described: G. ateriformis sp. nov. and G. tetrophthalmus sp. nov., known so far only from the Cape Verdes, but reported occurrence of the congeneric Atlantic-Mediterranean G. paganellus has not been confirmed. The pattern of free neuromast organs (sensory papillae) of the head lateral-line system in Mauligobius nigri and the habitat of this species are described for the first time and its distribution further discussed. Diversity of gobies and other inshore fishes at the Cape Verdes is briefly indicated.     

LXII.—Complanate alveolinids and associated foraminifera from the upper Cretaceous of the Middle East

Abstract

Pseudedomia complanata, sp. nov., Archaecyclus mid-orientalis, sp. nov., and Rotalia skourensis Pfender are described from limestones of Campanian age in the Kuwait Oil Company's Umm Gudair Well 1. The genus Pseudedomia is redefined and, on the basis of the detailed structures here described, is shown to belong to the Alveolinidae and not to the Peneroplidae; reference is also made to the occurrence of the genus in Iraq and Qatar.     

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.     

Two new species of Rhizorhina (Copepoda: Siphonostomatoida) from leptostracan and tanaidacean hosts

Summary

Two new species of parasitic copepods from the North Atlantic, Rhizorhina leptostracae associated with Nebaliella caboti, and Rhizorhina tanaidaceae from Leviapseudes hanseni, are described. Leptostracans and tanaids are new host groups for this genus. The systematic position of Rhizorhina is discussed.     

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.     

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.     

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).     

VIII.—Notes on the Silurian Brachiopod genera Delthyris,Uncinulina, and Meristina

Summary

In this paper the different interpretations of the genus Delthyris are discussed, and that given by Schuchert in 1913 is adopted with slight amendment. The species Delthyris elevata, D. crispa, D. elegans (nom. nov. for D. crispa, Hisinger, non Linnæus), and D. tenuilamellata, sp. n., from the British Silurian, are all described and figured.

The distinguishing characters of the genera Uncinulus and Uncinulina are pointed out, and Uncinulina is retained with U. fallaciosa as genotype. Rhynchonella stricklandi and Terebratula lewisi are transferred to the genus Uncinulina. Meristina tumida (Dalman) is shown to be a synonym of Meristina obtusa (Sowerby).

The British Silurian Spirifers can be separated into two groups:—(1) those with longitudinal folds and a transverse ornament of imbricating lamellæ (=Delthyris of Dalman) and (2) those with longitudinal folds bearing fine continuous longitudinal striæ (=Eospirifer of Schuchert).

The species referable to both these genera have as a rule been assigned to the genus Spirifer, from which, however, they differ in internal characters.     

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.     

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) kanmiyai Okada and Sidorenko, S. (Steganina) masanoritodai Okada and Sidorenko, S. (Steganina) ornatipes Wheeler and Takada, S. (Oxyphortica) dendrobium sp. nov., 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.     

Revision of the proctotrupoid genus Pelecinus Latreille (Hymenoptera: Pelecinidae)

The extant Pelecinidae consist of the single genus Pelecinus Latreille. This group is restricted to the continental New World; miscellaneous reports and specimens from Jamaica, Australia, India and Malaysia are errors. Three species are recognized: the widespread Pelecinus polyturator (Drury), found from the southern portions of the eastern provinces of Canada, the eastern USA (west to North Dakota, Colorado and New Mexico) and Mexico south to northern Argentina; Pelecinus thoracicus Klug revised status, from western Mexico; and Pelecinus dichrous Perty revised status from northern Argentina, Uruguay, Paraguay and south-eastern Brazil. Pelecinus rufus Klug, 1841 and Pelecinus annulatus Klug, 1841 are treated as junior synonyms of Pelecinus dichrous Perty, 1833. The status of Pelecinus polyturator var. apicalis Roman is discussed and the name is treated as a synonym of P. polyturator. The only recorded host species for the genus are for P. polyturator: Phyllophaga anxia (LeConte), P. drakei Kirby, P. futilis (LeConte), P. rugosa (Melsheimer) (Coleoptera: Scarabaeidae, Melolonthinae); and Podischnus agenor Olivier (Coleoptera: Scarabaeidae, Dynastinae).     

A new species of Halectinosoma (Copepoda,Harpacticoida) from the Isle of Man

Summary

A new species of Halectinosoma Lang, 1948, H. pterinum sp. nov. is described from the Isle of Man. Examination of this and some other species of the genus under high magnifications suggests that the diagnosis of the genus may have to be modified.
