TL;DR: In the taxonomic part synonymy and descriptions are given of the genus Amanita and its subgenus Lepidella, together with a key to the subgenera and the sections, and the term ’pileipellis’ is proposed to replace Fayod’s term ‘cuticula’.
Abstract: A historical survey of the delineation of the genus Amanita and its infrageneric classification is given. Morphological and other characters of Amanita are discussed, with emphasis on the characters and the behaviour of the volva. The term ‘pileipellis’ is proposed to replace Fayod’s term ‘cuticula’. In the taxonomic part synonymy and descriptions are given of the genus Amanita and its subgenus Lepidella, together with a key to the subgenera and the sections. Section Lepidella is provisionally monographed on the base of exhaustive examinations of type material, as far as available, and a usually limited number of additional collections. Of the 93 species recognized, sixteen are described as new, and seven provisionally as new species; three new names and four new combinations are introduced.

TL;DR: A revised generic classification of world Syrphini is proposed in this paper, based on characters of the adults of 318 described species plus approximately 85 more species as yet either undescribed or unidentified.
Abstract: A revised generic classification of world Syrphini is proposed. It is based on a study of characters of the adults of 318 described species plus approximately 85 more species as yet either undescribed or unidentified. Thirty-seven genera are recognized; keys to these genera, and to the smaller number of genera known from each of the major zoogeographic regions (except the eastern Palaearctic and Oriental) are presented. Eight new genera, Notosyrphus (South America), Exallandra (Ethiopian Region), Citrogramma (Oriental Region and Australia), Dideomima (Mexico), Hermesomyia (Ecuador), Pseudoscaeva (North and South America), Antillus (Haiti), and Giluwea (New Guinea), and two new subgenera, Melangyna (Austrosyrphus) (Australia and New Zealand) and M. (Melanosyrphus) (New Guinea), are described. Nine new species, in Melangyna (Melanosyrphus), Citrogramma, Hermesomyia, Antillus, and Giluwea, are described. The genus Orphnabaccha is transferred from the tribe Bacchini to the Syrphini, and the genus Toxomerus (including Mesograpta) is referred to the tribe Toxomerini. Maps showing the world distribution of each genus and subgenus, and figures of the male terminalia of the type-species of almost all genera and subgenera, are presented.The peculiar nature of the Neotropical fauna of Syrphini, with almost all species belonging to two large and very diverse genera, is compared with the situation in the rest of the world, where in most major regions the Syrphini consist mostly of a moderate number of medium-sized genera each of which shows much less diversity. Possible reasons for this difference, and for the great preponderance of more primitive Diptera among those with apparent transantarctic relationships, are suggested.

TL;DR: A group of tarsonemid mites, which are egg parasites of ipine bark beetles, is reviewed on a Holarctic basis, and the genus Iponemus (new name for Moseria Beer and Nucifora) is proposed and described for the group, and 24 species or subspecies are described, keyed, and illustrated.
Abstract: A group of tarsonemid mites, which are egg parasites of ipine bark beetles, is reviewed on a Holarctic basis. The genus Iponemus (new name for Moseria Beer and Nucifora) is proposed and described for the group, and 24 species or subspecies, including 19 described as new, are described, keyed, and illustrated. A detailed species-group description follows the generic description, and includes several structures hitherto not reported for species of Tarsonemidae. The variation and usefulness of the few characters available for distinguishing forms of Iponemus is discussed, and the provisional treatment of some forms as species and others as subspecies is explained.These mites are among the most host-specific associates of scolytid beetles: 16 of the 18 species or subspecies of Iponemus associated with the nearctic, pine-feeding ipines are monospecific, and each of the other two is restricted to two closely related species of hosts. The mites and the beetles together are considered with regard to size correlations, the degree of host specificity, the mites as taxonomic indicators of their hosts, biogeography, life history, and the role of egg parasitism by the mites in the population regulation of their hosts.

TL;DR: Toxicocalamus is expanded to include Apistocalamus and Ultrocalamus as subgenera and it is suggested that the solid maxillary teeth of Toxicocalamus are neomorphs, formed by backward extension of the fang-forming portion of the dental lamina.
Abstract: Toxicocalamus is expanded to include Apistocalamus and Ultrocalamus as subgenera. Pseudapistocalamus nymani, Apistocalamus pratti, A. loennbergi, and A. lamingtoni are considered geographic variations of Toxicocalamus (Apistocalamus) loriae. Toxicocalamus (Ultrocalamus) buergersi, synonymized with T. (U.) preussi by previous workers, is recognized as a distinct species because of many structural peculiarities (most notably, extension of the venom gland back within the body cavity nearly to the heart, as in Maticora). Three species are described as new: T. (Apistocalamus) spiblepidotus, characterized by large size and peculiar colouration; T. (A.) holopelturus, characterized by entire subcaudals and hemi-penial structure; and T. (Toxicocalamus) misimae, differing from the related T. longissimus in much lower ventral count and in having only 15 scale rows. A population from Garaina (Morobe Division) is believed to be of recent origin from hybridization between T. (A.) loriae and T. (T.) stanleyanus. Toxicocalamus is most closely related to the Australian genera called Brachyurophis, Melwardia, Narophis, Rhinelaps, and Rhynchoelaps by Worrell, but here all grouped in the genus Rhynchoelaps. This Australian genus and Toxicocalamus make up the Rhynchoelaps group, which does not include the genera Vermicella (for V. annulata only), Ogmodon, or Parapistocalamus. The lack of a diastema behind the fang in the elapid genera Kerilia, Ogmodon, and Toxicocalamus is not a primitive, but a specialized, feature, probably developed independently in each of these genera as a mechanism for coordinating the replacement rhythm of the fangs with that of solid teeth behind. It is suggested that the solid maxillary teeth of Toxicocalamus are neomorphs, formed by backward extension of the fang-forming portion of the dental lamina.

Abstract: A summary of the classification of the Neotropical Tabanidae (Diptera) is provided, with keys to subfamilies, tribes, genera and subgenera. Distribution and content of each taxon to subgenus is given, together with discussion of patterns of distribution and phylogeny. One new genus and 10 new subgenera are characterized, all based on previously described species.
TL;DR: This article established the monotypic genus Propotto, which was the only member of the assemblage that could be placed with certainty in one of the two recognized lorisid sub-families.
Abstract: REVIEWING the Miocene Lorisidae of Kenya and Uganda, Simpson1 established the new monotypic genus Propotto, which he considered was the only member of the assemblage that could be placed with certainty in one of the two recognized lorisid sub-families. He states, “Propotto is doubtless a lorisine if the (sub-familial) distinction is valid for the Miocene”.
TL;DR: The sexes of all but three of the North American species of Ips DeGeer can be separated reliably using characters on the frons, vertex of the head, protibiae, or declivital armature.
Abstract: The sexes of all but three of the North American species of Ips DeGeer can be separated reliably using characters on the frons, vertex of the head, protibiae, or declivital armature. In general, these secondary sexual characters are consistent within Hopping’s species groups.
TL;DR: Evidence from morphological and behavioral investigations shows that the genus Brachyphylla, presently referred to the subfamily Stenoderminae, is more properly regarded as a phyllonycterine.

TL;DR: One species is thought to be free-living, eight were found in association with coelenterates and four with echinoderms, and the three remaining species are probably also commensal but their hosts are as yet unknown.
Abstract: The study of the pontoniid fauna of the Indo-West-Pacific region has resulted in the discovery of numerous undescribed species of the genus Periclimenes Costa, 1844. A revision of this genus, the largest in the subfamily, at present in progress, cannot be completed for some time and it is considered advisable to provide preliminary descriptions of the species concerned. The brief descriptions and remarks given here will enable the species to be identified and may contribute to their recognition in other parts of their ranges, pending their full description and illustration.
Most of the species described are commensally associated with other marine invertebrates. One species is thought to be free-living, eight were found in association with coelenterates and four with echinoderms. The three remaining species are probably also commensal but their hosts are as yet unknown.
The hosts of most specimens have been preserved and are in the course of identification.
The holotype specimens will be deposited in the collections of the Rijksmuseum van Natuurlijke Historie, Leiden, and paratypes in the British Museum (Natural History), London, except where the specimens are already in a museum collection.
Some of the material upon which this report is based was collected during a study of the Indo-West-Pacific pontoniid shrimp fauna supported by a grant from the Nuffield Foundation.

TL;DR: The air-spora was investigated using an Andersen sampler and the genus Aspergillus showed a tendency to occur more frequently in the winter and spring.
Abstract: The air-spora was investigated using an Andersen sampler. During 1966 and 1967, 310 colonies of Aspergillus were recorded and 14 species were identified. The commonest species were A. amstelodami (Mangin) Thom & Church, A. fumigatus Fres., A. repens de Bary and A. versicolor (Vuill.) Tiraboschi. The genus as a whole showed a tendency to occur more frequently in the winter and spring.

TL;DR: A new homothallic species of Neurospora, N. lineolata, which was isolated from soil collected in the vicinity of Lahore, West Pakistan is described and represents the twelfth species now placed in the genus neurospora.
Abstract: SUMMARY A new homothallic species of Neurospora, N lineolata is described The fungus was isolated from soil collected in the vicinity of Lahore, West Pakistan Of the three other homothallic species with bipolar ascospores, N lineolata most closely resembles N africana; it differs, however, from this species by having narrower ascospores with numerous indistinct ribs and intercostal veins, and larger, beaked perithecia Ascospore germination in N lineolata is uni- and bipolar The bipolar pattern appears to predominate N lineolata represents the twelfth species now placed in the genus Neurospora A key to all species in the genus is provided During the present decade new species of Neurospora have been reported with surprising frequency Prior to 1960 only 7 species were included in the genus With the publication of this communication the total number now recognized rises to 12 Five new species have been discovered within a span of less than 7 years All of the new species are homothallic and have been isolated from soil This development, however, has not been entirely unsuspected, for when Nelson et al (5) described the second new species of this decade, Neurospora dodgei Nelson & Novak, they suggested that Neurosporas were probably much more common members of the soil mycoflora than heretofore believed They speculated that the discovery of additional species from soil should be facilitated by the application of a selective isolation technique developed by Novak and Backus (6) It did not take long for these speculations to be substantiated Mahoney, Huang and Backus (3) report in a current communication the discovery of two new species, N galapagosensis Mahoney & Backus and N africana Huang & Backus, from tropical soil They employed the selective isolation technique of Novak and Backus (6) in their

TL;DR: A taxonomic revision is made of the agaric genus Clitocybe (Fr.) Staude in Fennoscandia, the material comprising 3220 specimens, and some macroscopical, sporal, anatomical, ecological and other characters as well as certain responses to ultr~violet light are shown to be ± uniform throughout Clitocytes, and may thus be diagnostic of the genus.
Abstract: A taxonomic revision is made of the agaric genus Clitocybe (Fr.) Staude in Fennoscandia (i.e., Norway, Sweden, Finland, and parts of the northwest of the U.S.S.R.), the material comprising 3220 specimens. The delimitation of the genus mainly follows that of modern authors (e.g. SrNGER 1962), and in the discussion of some intergeneric differences attention is also drawn to some previously ignored ecological features. Agaricus nebularis [Batsch] Fries is acknowledged as the type species. Fairly comprehensive descriptions are given of the infrageneric diagnostic characters. Among the characters whose genetically controlled variation and diagnostic importance has often been ignored or undervalued by previous au~hors are : certain features of the pileus surface, the organization of the basal mycelium of the stipe, hygrophany, odour, the responses of some parts of the dried fruit body under ultra~violet light, the co1our of the spore deposit, several other spore characters, some of which are taken as the basis for a new system of spore shape classification, and pigmentation. Some characters are supposed to be original, and others derived. Several macrochemical reagents were tested, o.f which KOH proyed to be the most useful. Information on the cytology (e.g. the chromosome number) of one species is given. Some macroscopical, sporal, anatomical, ecological and other characters as well as certain responses to ultr~violet light are shown to be ± uniform throughout Clitocybe, and may thus be diagnostic of the genus. Considerable attention is paid to the habitat (substrate, forest site type , relation to lime content of ground, relation to human influence), f ruiting time, and geographical distribution of the species, which may be grouped in various, often clear-cut, categories with regard to each of these aspects. The largest numbers of species are found in the coniferous and mixed deciduous and coniferous, hemiboreal and southern boreal forests, the number of eastern taxa being considerable . Some species occur in alpine DryOJS heaths. Three species are recorded for the first time outside N. America, and two outside Asia. 3 subgenera, 16 sections, 2 subsections, 43 species, and 2 varieties are recognized, of which 1, 6 (in addition, 2 provisionally ), 2, 14, and 1, respectively, are described as new. 4 new combinations are introduced. Lectotypes or neotypes are proposed for several species. The author citations of some sectional and specific names are corrected . page Preface . .... .. ... . . ............. . . . 6
TL;DR: The results indicate that the analytical differences between species of this Gymnosperm genus are not so great as are known to occur in genera of the Angiospermae.
