During research for a taxonomical review of Campylocentrum, two South American species, C. kuntzei, described from Bolivia, and C. mattogrossense from Brazil, previously considered synonyms of Campylocentrum micranthum or C. robustum, were recognized as distinct species. This study reinforces the significant morphological differences among the taxa and proposes their re-establishment. Descriptions and illustrations, in addition to typifications, new synonyms, an identification key and their conservation statuses are provided.

Intestinal Trematodes

Species of Petasiger Dietz, 1909 are intestinal trematodes of aquatic birds. Despite the diversity of described species in Europe and North America, only two South American species are known and no species have been previously reported in birds from Brazil. During a study of helminths recovered from the Least Grebe, Tachybaptus dominicus(Linnaeus, 1766), from the state of Minas Gerais, Brazil, adult trematodes identified as Petasiger novemdecim Lutz, 1928 were found. The prevalence of infection was 55% (5/9), and the mean intensity of infection was 8 (1-32) parasites. Additionally, Biomphalaria straminea (Dunker, 1848) and Biomphalaria tenagophila (d'Orbigny, 1835) obtained from aquatic collections in the same state were found to harbor two species of echinostome cercariae of the Magnacauda group. These cercariae developed into metacercariae in experimentally infected Poecilia reticulataPeters, 1859. Attempts to obtain adult parasites in vertebrate host models (mice, chickens, ducks and canaries) were unsuccessful. The present study is the first report of Petasiger in Brazilian birds and the first morphological description of larvae of these parasites in Brazilian mollusks. Taxonomic aspects related to South American species ofPetasiger are discussed. It is suggested that, based on significant morphological differences observed in larval stages (i.e., larval dimensions) and adult parasites (i.e., disposition of the testes),Petasiger caribbensis Nassi, 1980 should be reconsidered as a distinct species from P. novemdecim.

Accurate Identification

Abstract Background Accurate identification of the species of Anopheles Meigen, 1818 requires careful examination of all life stages. However, morphological characters, especially those of the females and fourth-instar larvae, show some degree of polymorphism and overlap among members of species complexes, and sometimes even within progenies. Characters of the male genitalia are structural and allow accurate identification of the majority of species, excluding only those in the Albitarsis Complex. In this key, based on the morphology of the male genitalia, traditionally used important characters are exploited together with additional characters that allow robust identification of male Anopheles mosquitoes in South America. Methods Morphological characters of the male genitalia of South American species of the genus Anopheles were examined and employed to construct a comprehensive, illustrated identification key. For those species for which specimens were not available, illustrations were based on published illustrations. Photographs of key characters of the genitalia were obtained using a digital Canon Eos T3i attached to a light Diaplan Leitz microscope. The program Helicon Focus was used to build single in-focus images by stacking multiple images of the same structure. Results An illustrated key to South American species of Anopheles based on the morphology of the male genitalia is presented, together with a glossary of morphological terms. The male genitalia of type-specimens of previously poorly documented species were also examined and included in the key, e.g. Anopheles (Anopheles) tibiamaculatus (Neiva, 1906) which has a unique quadrangular-shaped aedeagus with an apical opening. Conclusions Male genitalia of South American species of Anopheles possess robust characters that can be exploited for accurate species identification. Distortion that can occur during the dissection and mounting process can obstruct accurate identification; this is most evident with inadvertent damage or destruction of unique features and interferes with correctly assigning shapes of the features of the ventral claspette. In some species, the shape, and anatomical details of the aedeagus also need to be examined for species identification. For members of the Myzorhynchella Series, both ventral and dorsal claspettes possess multiple characteristics that are herein used as reliable characters for species identification.

The taxonomy of Zamia montana and Z. oligodonta, two poorly understood species occurring at high elevations in the Western Cordillera of Colombia, is discussed. Zamia oligodonta was recently synonymized under Z. montana, but information derived from recent field studies is provided showing the two species are quite distinct. A treatment of both species is presented, including discussion of the major morphological differences between them and also between other South American species with prominently-veined leaflets. The conservation status of both species is evaluated.

AbstractWith 30 species, Tasmania is a major area of species diversity in the genus Menegazzia. Seven of these are new to science: M. abscondita Kantvilas, known from Tasmania and New Zealand, and M. athrotaxidis Kantvilas, M. hypogymnioides Kantvilas, M. petraea Kantvilas, M. ramulicola Kantvilas, M. subtestacea Kantvilas and M. tarkinea Kantvilas, all endemic to Tasmania. An identification key, descriptions based exclusively on Tasmanian collections, and detailed discussion of distribution, ecology, chemical composition and inter-species relationships are provided. All literature records of Menegazzia species pertaining to Tasmania are accounted for. New synonyms include: Menegazzia prototypica P. James and Parmelia pertusa var. coskinodes F. Wilson [synonyms of M. myriotrema (Müll. Arg.) R. Sant.], M. fertilis P. James [a synonym of M. platytrema (Müll. Arg.) R. Sant.] and Parmelia pertusa var. montana F. Wilson (a synonym of M. subtestacea). Incorrectly recorded species that should be deleted from the Tasmanian census include M. castanea P. James & D. J. Galloway (present on Macquarie Island) and M. testacea P. James & D. J. Galloway (endemic to New Zealand). The South American species, M. sanguinascens (Räs.) R. Sant., is recorded in Australasia (Tasmania) for the first time, whereas the widespread south-eastern Australian M. norstictica P. James is recorded for Western Australia. Salient features of the genus are discussed, including morphology, anatomy and chemistry. The biogeography of the genus is explored briefly. Twelve species (40%) are endemic to Tasmania, a level of endemism unmatched by any other species-rich genus on the island. Twelve species are shared with mainland Australia, eleven are shared with New Zealand, and only four species are shared with southern South America, all of which are sorediate, suggesting they are products of long-distance dispersal.

We propose 31 synonyms for nine South American species of Miconia (Melastomataceae), mostly from the Atlantic Forest in Brazil (with one species in “campos rupestres” and another from the Atlantic Forest in Paraguay); all belong to the ‘Miconia discolor clade’. Of these synonyms, 19 are species and 12 are varieties or subspecies, all of them described by the end of the XIX or early XX centuries, and most of them known in herbaria mostly from isotypes or syntypes (except for Miconia cabucu, M. chartacea and M. saldanhae). Miconia flammea var. major is synonymized under M. brunnea; Miconia amambayensis and M. oblongifolia under M. buddlejoides; Miconia augusti, M. divaricata, M. fasciculata subsp. catharinensis, M. fasciculata var. robusta, M. fluminensis, M. gilva, M. rabenii, M. saldanhae, M. saldanhae var. grandifolia and M. saldanhae var. subsessilifolia under M. fasciculata; Miconia chartacea, M. chartacea var. angustifolia, M. chartacea var. brevifolia, M. chartacea var. longifolia and M. chartacea var. miqueliana sob M. flammea; Miconia altissima, M. cabucu, M. formosa var. angustifolia, M. gigantea, M. mourae, and M. ovalifolia under M. formosa; Miconia ovata under M. organensis; Miconia maximowicziana and M. maximowicziana var. major under M. sclerophylla; Miconia eichleri, M. eichleri var. australis, and M. pseudoeichleri under M. valtheri; and Miconia argyraea under M. willdenowii. We also designate lectotypes for all names but M. fasciculata subsp. catharinensis, M. maximowicziana and M. ovata, which already have holotypes designated by the respective authors. We corrected the spelling of M. buddlejoides (previously known as M. budlejoides), M. saldanhae (formerly M. saldanhaei) and M. mourae (formerly M. mouraei). In the present century, 14 species of Miconia s.s. have been described for the Atlantic Forest, and another 43 species, subspecies and varieties have been synonymized (including the ones performed here). This means that a significant inflation of names has been corrected, since the genus has been deflated by 29 taxa. The synonyms proposed here will help students of the family and other researchers employ the correct names in biological studies, which in turn will help to fine tune biodiversity studies and conservation efforts.

Morphological Differences

The genus Celtis L. (Cannabaceae) comprises around 73 species distributed in temperate and tropical regions of both hemispheres. Most South American species belong to the subgenus Mertensia Planch., and they are characterized by showing high morphological plasticity. A recent taxonomic revision of this group was carried out with an excessively reductionist criterion regarding the number of accepted species and that does not clearly reflect the morphological differences among them. In order to contribute to the correct delimitation of the specific entities, a morpho-descriptive approach is presented for ten taxa of the genus Celtis (C. brasiliensis, C. chichape, C. clausseniana, C. fluminensis, C. pallida var. pallida, C pallida var. discolor, C. serratissima, C. spinosa, C. spinosissima and C. tala) growing in South American Southern Cone. The morphology was analyzed through the use of a stereomicroscope and/or the tpsDig program for digital images of specimens. As a result, a key is provided for the determination of the aforementioned species and a detailed morphological description of the vegetative (habit, bark, branches, spines, brachyblasts, indumentum and leaves) and reproductive structures (inflorescences, flowers, fruits and endocarp -pyrene-). In addition, a specimen collection guide is proposed with a list of the main morphological characters that should be observed in the field, to facilitate future identifications.
