In recent years, new generic circumscriptions have been proposed in the Hedyotis–Oldenlandia complex. A comprehensive revision of Indian Hedyotis sensu lato, published in 2004, was based on a broad generic concept for the genus and does not uphold new generic delimitations. Therefore, the present article has been prepared to apply modern generic concepts to the Indian taxa. In India, 102 taxa are currently recorded under the Hedyotis–Oldenlandia complex, belonging to 12 genera (i.e. Debia, Dentella, Dimetia, Edrastima, Exallage, Hedyotis, Involucrella, Kohautia, Leptopetalum, Neanotis, Oldenlandia and Scleromitrion). The characters of these genera have been reviewed and their species enumerated, and consequently, seven new combinations are proposed. Scleromitrion in India is discussed in relation to its phenotypic variation, and a key to the six recognised species is presented.

All available phylogenetic evidence indicates that the rattan genus Calamus, the largest of all palm (Arecaceae) genera, is non-monophyletic and that the four remaining genera of subtribe Calaminae (Calameae: Calamoideae), Ceratolobus, Daemonorops, Pogonotium and Retispatha, are nested within it. This issue has not yet been adequately addressed in palm classifications, with recent authors preferring to wait for further phylogenetic evidence before revising the limits of the genera. Here, an alternative solution is proposed that is both pragmatic and phylogenetically robust. An expanded Calamus is recognised into which Ceratolobus, Daemonorops, Pogonotium and Retispatha are subsumed. This broad generic concept, which includes ca. 520 species, has practical advantages as it is more clearly defined by morphological and anatomical characters, and resolves potential biases introduced to recent eco-evolutionary research on palms by the non-monophyly of critical genera. Future phylogenetic research may yet provide an alternative means of delimiting these genera, but the broad sense Calamus proposed here is a justifiable alternative that can be adopted immediately. Nomenclatural synopses transferring currently accepted species of Ceratolobus, Daemonorops and Pogonotium to Calamus are provided, including 70 new combinations and 12 replacement names.

The validity of the generic concept of Babingtonia Lindl. adopted by Bean (1997a) is tested in the light of molecular and morphological data. Molecular analyses support recognition of segregate genera, none of which is closely related to the type of the genus, Babingtonia camphorosmae, a western Australian species. Two genera, Sannantha and Kardomia, are described as new and a third genus, Harmogia, resurrected from synonymy; new combinations are provided in the new genera. A fourth group, consisting of ‘Babingtonia’ behrii and its allies, appears distinct but, as a predominantly southern group, with numerous western Australian representatives, is not treated further.

AbstractA broad generic concept is adopted for Catillaria, and the following new combinations made: C. aphana (Nyl.) Coppins, C. modesta (Müll. Arg) Coppins (the basionym, Lecidea modesta Müll. Arg., being lectotypified), C. picila (Massal.) Coppins, and C. scotinodes (Nyl.) Coppins. Lecidea botryiza Nyl. ex Stirton is added to the synonymy of Micarea lutulata. Catillaria rhypodiza is transferred to Halecania, and a new, sorediate, corticolous species of that genus, H. viridescens Coppins & P. James, is described.

We describe one new genus (Brachinepticula Stonis & Diškus, gen. nov.) with two new species (B. plurilobata Diškus & Stonis, sp. nov., B. elongata Remeikis & Stonis, sp. nov.), and one species with uncertain taxonomic position (Johanssoniella bina Remeikis & Stonis, sp. nov.). We also provide diagnostic characters and an updated annotated catalogue of the following related genera: newly restored Johanssoniella Koçak, Brachinepticula gen. nov., Enteucha Meyrick (s. str.) and Manoneura Davis. In the Annotated Catalogue, we provide five new combinations and new data on morphology, biology, and distribution of some species, including the first photographic documentation of Manoneura basidactyla Davis discovered in the Amazon rainforest, results of re-examination of the male genitalia of the European Johanssonia acetosae (Stt.), also the first documentation of the male genitalia, host plant and leaf mines of the little known Johanssoniella diplocosma (Meyrick) from the Himalayas. All new taxa treated in the paper are illustrated with drawings and (or) photographs of the adults and genitalia; photographs of the leaf mines of Brachinepticula plurilobata Diškus & Stonis, sp. nov. and Johanssoniella diplocosma (Meyrick) are also provided.

New collections of six Squamarina species from type localities in China were studied. The comparison of morphological characteristics and secondary metabolites with those of the type specimens and phylogenetic analyses suggest that S. callichroa and S. pachyphylla belong to Rhizoplaca, S. semisterilis belongs to Lobothallia and S. chondroderma should be retained in Lecanora temporarily. Only two species, S. kansuensis and S. oleosa, remain in Squamarina. The new combinations Lobothallia semisterilis (H. Magn.) Y. Y. Zhang, Rhizoplaca callichroa (Zahlbr.) Y. Y. Zhang and R. pachyphylla (H. Magn.) Y. Y. Zhang are proposed. Detailed descriptions to aid the identification of these species, distributions and phylogenetic trees, based on multiple collections, are presented. The generic concept of Squamarina is recircumscribed in this study.

The family Parasitidae comprises two subfamilies, Parasitinae and Pergamasinae. A generic concept of this family is not stable and requires a revision. The number of genera varies depending on authors and their view on the systematics of the family, especially on the rank of taxa. We recognize 23 genera within Parasitinae and 22 genera within Pergamasinae, 4 of them are subdivided into subgenera. A dichotomous key for separation of genera and subgenera is provided. A new genus, Coprocarpais n. g. with type species Parasitus copridis Costa, 1963 is proposed and a diagnosis is given. The genus Erithosoma is not assigned to any subfamily because a description of females is missing. The most pressing taxonomic problems at generic and subgeneric levels are discussed. Fourteen new combinations are proposed.

The genus Aximopsis is redefined, an hypothesis of its phylogenetic placement within Eurytominae is presented, and seven species are described as new: A. anubis Gates, A. arietinis Gates, A. hespenheidei Gates, A. hippolytis Gates, A. lanceolepis Gates, A. pythmenis Gates, and A. vogti Gates. Three new combinations are proposed: Philolema javensis (Girault), 1917, n. comb., Philolema tephrosiae Girault, 1917, n. comb., and Eurytoma tricolor n. comb. Aximopsis elegans Masi (1917) is placed incertae sedis. Aximopsis ovi Girault and A. tumidiscapi Girault are nomina nuda.

Although Eugenia and Plinia genera belong to different subtribes in Myrteae (Myrtaceae), shared morphological features have led to frequent mistaken identity to these species. Molecular phylogeny and morphological studies in Plinia show that Plinia martinellii and Plinia sebastianopolitana should be combined within the generic concept of Eugenia. In addition, two synonymizations under Plinia sebastianopolitana and one under Plinia martinellii are proposed. Commentary on these nnomenclatural adjustments, as well as on morphological and geographical data related to the evolution of these lineages is also provided.

Abstract: Recently, Duriez, Fontaine and Hutsebaut (2000) and Fontaine, Duriez, Luyten and Hutsebaut (2003) constructed the Post-Critical Belief Scale in order to measure the two religiosity dimensions along which Wulff (1991 , 1997 ) summarized the various possible approaches to religion: Exclusion vs. Inclusion of Transcendence and Literal vs. Symbolic. In the present article, the German version of this scale is presented. Results obtained in a heterogeneous German sample (N = 216) suggest that the internal structure of the German version fits the internal structure of the original Dutch version. Moreover, the observed relation between the Literal vs. Symbolic dimension and racism, which was in line with previous studies ( Duriez, in press ), supports the external validity of the German version.

Le présent article tente d’effectuer un rapprochement entre un article européen de Rossel et Merceron et un livre américain de Reid Meloy, tous deux consacrés à l’analyse des organisations psychopathiques. Si tous les auteurs s’entendent sur l’économie narcissique du psychopathe, le choix de la population d’étude diffère quelque peu, en raison de l’approche structurale des premiers et de l’approche symptomatique du second. Tandis que l’étude suisse ne retient que des psychopathes du registre des états-limites, l’étude américaine inclut également des psychopathes de niveau psychotique. Par contre, la mésentente règne au niveau des outils d’analyse du discours psychopathique: analyse statistique et échelles validées chez Meloy; approche qualitative chez Rossel et Merceron. Aux premiers, l’on reprochera un certain réductionisme et appauvrissement du discours, prix à payer pour le respect de la standardisation et de la cotation. Aux seconds, l’on reprochera l’absence de toute quantification qui pose problème lorsque l’on aborde la question de la validité des données. Néanmoins, Européens et Américains s’entendent sur la notion d’un fonctionnement psychopathique. La relation d’objet est marquée par la pulsion agressive et ses dérivatifs, par la recherche de pouvoir et de contrôle. La lutte contre la dépendance est déduite chez Meloy de l’absence de réponse de texture et chez Rossel et Merceron de l’absence de contenus de dépendance. La qualité narcissique des représentations d’objet est mise en évidence, chez Meloy, par le biais de l’investissement du paraître, chez Rossel et Merceron par l’importance du processus d’externalisation. La dévalorisation des objets est aussi décrite. Ni les uns ni les autres ne font réellement référence à l’angoisse car cette angoisse qualifiable d’anaclitique s’exprime justement sous des manifestations tout à fait opposées. Le vide intérieur est déduit, chez Meloy, à partir de l’ennui que vit le psychopathe et, chez Rossel et Merceron, à partir de la survalorisation de la référence au réel. Une grande convergence existe entre les deux écrits au sujet des mécanismes de défense. Tous les auteurs s’accordent sur la prépondérance du clivage et du déni, un déni par le mot et l’acte chez Meloy, un déni hypomaniaque chez Rossel et Merceron. De part et d’autre de l’Atlantique, on s’accorde également pour attribuer une place importante à l’identification projective et à l’identification à l’agresseur. Par ailleurs, Rossel et Merceron démontrent comment à travers les caractéristiques de l’énonciation et les nuances de la verbalisation du psychopathe, il est possible d’inférer son non-investissement de la mentalisation et du savoir au profit d’un surinvestissement de l’agir. La complémentarité, voire la similarité, des commentaires dans les deux ouvrages devrait réconforter certains cliniciens, désarmés devant le fossé qui semble parfois régner entre la littérature des deux continents et confirmer, qu’indépendamment du type de méthodologie et de validation choisi, l’observation clinique du psychologue expérimenté demeure la pierre angulaire de toute recherche en psychopathologie.
