Notes on some larval and pupal chironomids (Diptera) from Lake Kariba,Rhodesia

Summary

The effects of hydrolysable tannin and condensed tannin on the feeding of Schistocerca gregaria and Locusta migratoria are described. An attempt is made to explain the different effects of tannins in the presence of different nutrients. The ecological significance of these findings is discussed.     

XIII.—Notice of three new species of Sinusigers,a genus of Brachiocephalous Mollusks

Summary

The reproductive organs of the male and female Gryllodes sigillatus, together with their associated muscles, are described in detail. The male reproductive organs are characterized by the presence of the accessory gland tubules and the absence of sperm vesicles. The presence of a pair of lateral pouches on the genital chamber and a chitinous bursa copulatrix at the posterior end of the spermathecal duct are peculiar features of the female reproductive organs. The testes and the ovaries are attached by the testicular and ovariolar ligaments respectively to the tergum of the first abdominal segment.     

Lepeophtheirus pectoralis (O. F. Müller, 1776); a description,a review and some comparisons with the genus Caligus Müller, 1785

Summary

The parasitic copepod Lepeophtheirus pectoralis (Müller, 1776) is described. A review of the hosts indicates that this species is primarily a parasite of members of the family Pleuronectidae although it has been recorded from representatives of ten other families of fishes. The geographical range of L. pectoralis includes the North Eastern Atlantic Ocean, the western part of the Baltic Sea and the White Sea. The similarities between Lepeophtheirus Nordmann, 1832 and Caligus Müller, 1785 are discussed and it is concluded that the only constant morphological discriminant between these two genera is the presence or absence of lunules.

Apogon andhrae,a new species of apogonid fish from the Bay of Bengal

Summary

A new species of Apogon from Indo-West Pacific is described. A. andhrae sp. nov. can be distinguished from the closely related A. ellioti Day by the absence of the pigment band on the anal fin and of pigment spots on the dorsal side of head, and the presence of a narrow black edge to the caudal fin.     

A new genus of Neotropical whitefly,secreting blue-iridescent wax (Sternorrhyncha,Aleyrodidae, Aleurodicinae), and its parasitoids (Hymenoptera,Aphelinidae)

Azuraleurodicus pentarthrus Martin gen. and sp. n. is described from three different host plant families in Central and northern South America. Adults of both sexes were reared in culture and adult characters are discussed in addition to those of puparia. The systematic position of Azuraleurodicus within the Aleurodicinae is discussed. One new combination, Aleuronudus ferrisi (Sampson and Drews) comb. n., is here proposed in the course of discussion. The secretion of blue wax by whiteflies is discussed and illustrated by colour photographs. Two species of hymenopterous parasitoids, Dirphys aphania Polaszek sp. n. and Encarsiella pithecura, Polaszek sp. n. emerged from puparia of Azuraleurodicus pentarthrus and are here described.     

LVII.—Pityosporites Westphalensis,sp. nov., an abietineous type pollen grain from the coal measures of Britain

Abstract

Recent investigations of the microfloras of the Upper Carboniferous coal-seams of a part of the South Wales Coalfield have demonstrated the presence in these coals of pollen grains of typical Abietineous aspect referable to the genus Pityosporites Seward. A new species—P. westphalensis—is described. The grains are found distributed through the seam as part of the overall microflora and are not associated with any male fructifications or sporangia. However, on morphological grounds they are referable to the Coniferae and indicate the existence during late Carboniferous (Coal Measures) times of a group of conifers which quite probably were the early representatives of the Abietineae. The geographical and vertical distributions of Pityosporites in the British Coal Measures are given as far as they are known at present, and it is concluded that this hitherto unknown group of Coal Measures conifers made a small but nevertheless significant contribution to the floras of those times.     

Rediscovery of the Hawaiian endemic bark beetle Xyleborus pleiades Samuleson, 1981 on Moloka‘i,with records of three new exotic bark beetles for the island (Coleoptera: Curculionidae: Scolytinae: Xyleborini)

ABSTRACT

During the course of a targeted bark beetle survey of the Hawaiian Islands, insect sampling undertaken in native forest biotopes on Moloka‘i island revealed the presence of one native and three exotic species of xyleborine bark beetles (Coleoptera: Curculionidae: Scolytinae: Xyleborini) hitherto not recorded from the island. We present detailed new island records for these species, which include the second record of Xyleborus pleiades Samuelson, 1981, an endemic Hawaiian species not recorded in over 50 years, and previously known only from two specimens from the island of Maui. The three newly recorded introduced species are widespread pantropical beetles of actual or potential pest status: Xyleborus affinis Eichhoff, 1867, Xyleborinus saxesenii (Ratzeburg, 1837), and Xylosandrus crassiusculus (Motschulsky, 1866). The importance of the records is briefly discussed, and all newly recorded species are illustrated in colour photographs.     

Colanthura,Califanthura, Cruranthura and Cruregens,related genera of the paranthuridae (Crustacea: Isopoda)

Summary

The relationships between the genera Colanthura Richardson, Califanthura Schultz, Cruranthura Thomson and Cruregens Chilton are discussed and presented from a cladistic point of view. Of the 17 species known three are described as new, Colanthura bruscai, Colanthura kensleyi and Califanthura lowryi.     

Hishimonus Ishihara, 1953 and Hishimonoides Ishihara, 1965 as synonyms of Cestius Distant, 1908 (Cicadellidae: Hemiptera)

Summary

A re-examination of Haplomunna Richardson (1908) reveals a close relationship between this genus and Munella Bonnier (1896), Abyssaranea Wilson &; Hessler (1974) and Thylakogaster ibid. As a consequence, a new family, Haplommunidae, is erected to contain these four genera. The systematic problems with this new grouping, its relation to the Dendrotionidae, and some peculiarities of its members are discussed. A key and the geographical ranges of the four genera are included. A generic diagnosis for Haplomunna is given, and H. caeca (Richardson, 1905) and H. hubbsi, sp. nov. are described.     

The relationship of Recent foraminifera to the sedimentary facies in the turbulent zone,Cardigan Bay

Summary

The behaviour and feeding habits of T. biguttatus, T. fraternus, T. taeniola. T. gratus and H. decora were studied in the vicinity of a resting cattle herd. The observations could be substantiated by experiments with flies on restrained animals and an examination of 11 189 Tabanidae in regard to presence and size of fresh blood meals.

By relating these findings to the principles of mechanical transmission, the small Tabanidae T. gratus and H. decora did not show the expected behaviour of potential vectors. Of the large species, T. biguttatus and T. fraternus did not qualify on the basis of their feeding habits. It was concluded that T. taeniola fulfilled, in regard to behaviour and feeding habits, all requirements for mechanical disease transmission under natural conditions.

Summary

Facts are given on the preoviposition and oviposition of mated females of A. curvipes. The size, shape, colour, incubation and hatching of eggs are described. The morphology and development of neanides at various stages are described—and compared with some data on the egg and neanide periods of a related species A. phasiana. Differences are pointed out between the neanides and adults of A. curvipes and the longevity and sex ratio of the adults are discussed.     

The West African Shad,Ethmalosa fimbriata (Bowdich, 1825): synonymy,neotype

Summary

Type specimens of Aegocrioceras quadratum (Crick), A. koeneni Spath and A. subseeleyi Spath are described and figured. A. subseeleyi is probably a junior subjective synonym of A. bicarinatum (Young &; Bird). The interpretation of the other English species of Aegocrioceras listed by Spath (1924) is discussed and a new species, A. densiradiatum, is erected.

Stridulatory organs of the elm bark beetles Scolytus multistriatus Marsham and Scolytus scolytus Fabricius

Summary

In Scolytidae, stridulatory organs are not usually found in the sex which selects the breeding site and begins the gallery. Exceptions in the literature refer to the genera Dendroctonus and Scolytus. The presence of stridulatory organs in both sexes of the elm bark beetles S. multistriatus and S. scolytus is reported here. The structure of the stridulatory apparatus is described, and the possible role of stridulation in the behaviour of these species is discussed.
