Annotated Checklist

To contribute to the taxonomic knowledge of barnacles in this understudied area, the first checklist of barnacles from the Moluccas is presented, including additional information on morphology, distribution, and substrate as well as molecular data. The species of barnacles from the Moluccas have been determined using morphological analysis and DNA sequences. During 19 field trips conducted between January 2016 and September 2017, 1,513 specimens of 24 species of intertidal and one species of deep-sea barnacles were collected from 51 localities from the islands. Morphological and molecular analysis of the collected material detected members of three families of stalked barnacles and four families of acorn barnacles. In addition to sampling in the field, we also surveyed the literature on barnacles from the Moluccas. In total, our checklist comprises 97 species from the Moluccas including 23 new records, two of them yet to be described species. Results suggest that the Moluccas have a much higher diversity of barnacles than previously known, for example, from the reports of Challenger and Siboga expeditions. For further work, routine application of molecular systematics could aid the detection of cryptic species, while increased sampling of more islands and a taxonomic revision of several groups would likely lead to an even higher number of species than currently known.

A worldwide taxonomic revision of the species belonging to the moss genus Chionoloma Dixon (Pottiaceae) is here presented. Our work is based on the morphological analysis of more than 2600 specimens deposited in different herbaria or collected during field trips. A total of 131 names were found and their nomenclatural types were examined, resulting in the lectotypification of 45 names. It is concluded that Chionoloma is composed of 22 species and one variety, seven of them are here newly combined (C. circinatum (Besch.) M. Alonso, M. J. Cano & J. A. Jiménez; C. cylindrotheca (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. hyalinoblastum (Broth.) M. Alonso, M. J. Cano & J. A. Jiménez; C. melanostomum (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. orthodontum (Müll. Hal.) M. Alonso, M. J. Cano & J. A. Jiménez; C. sarawakense (Dixon) M. Alonso, M. J. Cano & J. A. Jiménez; and C. stenocarpum (Thér) M. Alonso, M. J. Cano & J. A. Jiménez). Moreover, 42 names are newly synonymized and a total of 74 new records for various countries are reported. Keys, descriptions, illustrations, photographs, and distribution data of each species are provided.

The genus Panaspis in Angola is represented by four species, most of them part of taxonomically and nomenclaturally challenging species-complexes. We present a taxonomic revision of the group in the region and describe one new species, Panaspis mocamedensis sp. nov., endemic to the lowland areas of the Namibe province, southwestern Angola. Phylogenetic analysis using a combination of mitochondrial (16S, cytb) and nucleares (RAG1, PDC) markers, as well as morphological and meristic data support the recognition of the new species. In addition, these data support the presence of nominotypical Panaspis cabindae, P. wahlbergi and P. maculicollis in Angola. Reexamination of the Angolan population of P. breviceps was based on morphological analysis, as no molecular data from Angola is available for this species. According to our results, this population likely represents the nominotypical form, but due to its complex taxonomic and nomenclatural history and the lack of molecular data, this population needs to be reconsidered when molecular data become available. The description of a new species and revision of the Angolan Panaspis contributes to a better understanding of the true species richness of the Angolan herpetofauna, as well as to understanding the major biogeographic patterns of the region. A key to Angolan Panaspis species is also presented.

Passiflora subgenus Astrophea is one of the five currently recognized subgenera of Passiflora. It is distributed throughout the neotropics, mainly in the Amazon rainforest. We present a taxonomic revision of species of Passiflora subgenus Astrophea occurring in Brazil, based on vegetative, floral and pollen morphology. A total of 31 species and 2 varieties were recognized and classified into four sections and two series. Four species were placed in section Capreolata, 2 species in section Leptopoda, 17 species and 2 varieties in section Pseudoastrophea and 8 species in section Botryastrophea, of which 4 were included in series Botryastrophea and 4 in series Carneae. Astrophea individuals can be identified by their variable habit, entire leaf-blades, two glands at the apex of the petiole or at the base of the leaf blade and white flowers with yellow corona and pink to purplish or red to orange hypanthium. We discuss the rediscovery of P. elliptica after 71 years and present new records of P. chlorina from Minas Gerais, additional information on the little-known P. phaeocaula, P. sclerophylla and P. mansoi var. glabra. Identification keys, complete descriptions, geographical distribution maps, etymology, taxonomic comments and illustrations are presented.

Thirty-six species of various thecate hydroids occur in two recent, deep-water collections from off New Caledonia. Of these, nine are new, namely Solenoscyphus subtilis Galea, sp. nov., Hincksella immersa Galea, sp. nov., Synthecium rectangulatum Galea, sp. nov., Diphasia alternata Galea, sp. nov., Dynamena opposita Galea, sp. nov., Hydrallmania clavaformis Galea, sp. nov., Symplectoscyphus acutustriatus Galea, sp. nov., Symplectoscyphus elongatulus Galea, sp. nov. and Zygophylax niger Galea, sp. nov. The male and female gonothecae of Caledoniana decussata Galea, 2015, the female gonothecae of Caledoniana microgona Galea, 2015, as well as the gonothecae of both sexes of Solenoscyphus striatus Galea, 2015 are described for the first time. The systematic position of the genera Solenoscyphus Galea, 2015 and Caledoniana Galea, 2015 is discussed on both morphological and molecular grounds, and both are confidently placed within the family Staurothecidae Maronna et al., 2016. In light of the molecular data, the genera Billardia Totton, 1930 and Dictyocladium Allman, 1888 are assigned to the families Syntheciidae Marktanner-Turneretscher, 1890 and Symplectoscyphidae Maronna et al. , 2016, respectively. The previously undescribed gonothecae of Hincksella neocaledonica Galea, 2015, and the male gonothecae of Sertularella tronconica Galea, 2016, were found. Thyroscyphus scorpioides Vervoort, 1993, a peculiar hydroid with putative stem nematothecae, is redescribed and assigned to the new genus Tuberocaulus Galea, gen. nov. Noteworthy new records from the study area are: Tasmanaria edentula (Bale, 1924), Hincksella sibogae Billard, 1918, Dictyocladium reticulatum (Kirchenpauer, 1884), Salacia sinuosa (Bale, 1888) and Billardia hyalina Vervoort & Watson, 2003. Most species are illustrated to facilitate their identification, and the morphology of the new ones is compared to that of their related congeners.

The South Australian members of the flat-millipede genera Oncocladosoma Jeekel, 1985 and Somethus Chamberlin, 1920 are revised using an integrative approach incorporating sequence data and morphology. The partial mitochondrial cytochrome c oxidase subunit I (COI) barcoding gene and partial nuclear ribosomal 28S rRNA were amplified and sequenced for 15 Oncocladosoma specimens and 10 Somethus specimens and the datasets were used for molecular phylogenetic analysis and genetic distance determination. Both morphology and molecular data indicate that all species of Oncocladosoma fall within Somethus, and therefore, Oncocladosoma is synonymised with Somethus. Within those species supported by molecular data, features of the solenomere tip are relatively stable and useful for species identification. 28S rRNA has proven to provide sufficient nucleotide variation to provisionally discriminate species. Oncocladosoma castaneum ingens Jeekel, 1985, O. clavigerum Jeekel, 1985 and O. conigerum Jeekel, 1985 are junior synonyms of Somethus castaneus, comb. nov., and Somethus modicus Jeekel, 2002 is a synonym of S. scopiferus Jeekel, 2002. New records and electron scanning micrographs of gonopods are provided for S. castaneus, comb. nov., S. inflatus (Jeekel, 2002), comb. nov., S. lancearius Jeekel, 2002, S. scopiferus Jeekel, 2002, and Somethus grossi Jeekel, 1985, together with a key to the South Australian species of Somethus.

AbstractThe Clarion-Clipperton Zone (CCZ), located in the abyssal equatorial Pacific, has been subject to intensive international exploration for polymetallic nodule mining over the last four decades. Many studies have investigated the potential effects of mining on deep-sea ecosystems and highlighted the importance of defining environmental baseline conditions occurring at potential mining sites. However, current information on biodiversity and species distributions in the CCZ is still scarce and hampers the ability to effectively manage and reduce the potential impacts of mining activities. As part of the regulatory regimes adopted by the International Seabed Authority, concession holders are required to conduct an environmental impact assessment and gather baseline data on biodiversity and community structure in relation to their license areas. In the present study, we used an integrative molecular and morphological approach to assess species richness and genetic variation of deep-sea scavenging amphipods collected in two nodule-mining exploration areas (UK-1 and OMS-1 areas) and one Area of Particular Environmental Interest (APEI-6) in the eastern part of the CCZ. We analyzed the DNA sequences of the cytochrome c oxidase subunit I gene of 645 specimens belonging to ten distinct morphospecies. Molecular data uncover potential cryptic diversity in two investigated species, morphologically identified as Paralicella caperesca Shulenberger & Barnard, 1976 and Valettietta cf. anacantha (Birstein & Vinogradov, 1963). Our study highlights the importance of using molecular tools in conjunction with traditional morphological methods for modern biodiversity assessment studies, particularly to evaluate morphologically similar individuals and incomplete specimens. The results of this study can help determine species identity and ranges, information which can feed into environmental management.

Origin And Evolution

The genus Dysdera Latreille, 1804, a species-rich group of spiders that includes specialised predators of woodlice, contains several complexes of morphologically similar sibling species. Here we investigate species limits in the D. erythrina (Walckenaer, 1802) complex by integrating phenotypic, cytogenetic and molecular data, and use this information to gain further knowledge on its origin and evolution. We describe 16 new species and redescribe four poorly known species belonging to this clade. The distribution of most of the species in the complex is limited to southern France and the north-eastern Iberian Peninsula. The species studied do not show any obvious differences in habitat preference, and some of them even occur sympatrically at certain sites. They probably feed on the same type of prey as they readily capture woodlice. On the other hand, they differ in body size, mouthparts shape, sculpturing of carapace, morphology of the copulatory organs, karyotype and DNA sequences. Experimental interspecific mating showed a partial precopulatory behavioural barrier between D. erythrina and D. cechica, sp. nov. Our data suggest that karyotype evolution of the complex included chromosome fusions and fissions as well as translocations (between autosomes as well as autosomes and sex chromosomes). We hypothesise that chromosome rearrangements generating reproductive incompatibility played a primary role in speciation within Dysdera complexes. Dysdera spiders are poor dispersers, and their original distribution areas (forested areas in the Mediterranean) were repeatedly fragmented during Quarternary climatic oscillations, facilitating integration of chromosome rearrangements into karyotypes by genetic drift. Sympatric occurrence of closely related species may have been promoted by prey segregation as suggested by differentiation in body size in co-occurring species. The following new species are described: D. catalonica, sp. nov., D. cechica, D. dolanskyi, sp. nov., D. fabrorum, sp. nov., D. garrafensis, sp. nov., D. graia, sp. nov., D. kropfi, sp. nov., D. minairo, sp. nov., D. portsensis, sp. nov., D. pradesensis, sp. nov., D. pyrenaica, sp. nov., D. quindecima, sp. nov., D. septima, sp. nov., D. stahlavskyi, sp. nov., D. tredecima, sp. nov. and D. undecima, sp. nov.

The Status

The freshwater prawns of the genus Macrobrachium Spence Bate, 1868 are widely distributed in rivers of tropical and subtropical regions and represent an interesting group with controversial taxonomy. The morphological characters traditionally used to separate species have shown a high intraspecific variation. Doubts about the status of M. birai Lobão, Melo & Fernandes, 1986, M. holthuisi Genofre & Lobão, 1978 and M. petronioi Melo, Lobão & Fernandes, 1986 have been arisen due to the high resemblance of the former two species with M. olfersi (Wiegmann, 1836), and the latter one with M. potiuna (Müller, 1880). Therefore, we performed a detailed morphological analysis of these species, including new characters not usually used in the species recognition. The present results here with molecular data lead us to conclude that M. birai and M. holthuisi are junior synonyms of M. olfersi, and M. petronioi is a junior synonym of M. potiuna. Considering these synonymies, 17 valid species are now reported for the Brazilian territory.

AbstractThe eastern Mediterranean basin hosts a remarkably high plant diversity. Historical connections between currently isolated areas across the Aegean region and long-distance dispersal events have been invoked to explain current distribution patterns of species. According to most recent treatments, at least two Cymbalaria species occur in this area, Cymbalaria microcalyx and C. longipes. The former comprises several intraspecific taxa, treated at different ranks by different authors based on morphological data, evidencing the need of a taxonomic revision. Additionally, some populations of C. microcalyx show exclusive morphological characters that do not match any described taxon. Here, we aim to shed light on the systematics of eastern Mediterranean Cymbalaria and to propose a classification informed by various sources of evidence. We performed molecular phylogenetic analyses using ITS, 3’ETS, ndhF and rpl32-trnL sequences and estimated the ploidy level of some taxa performing relative genome size measures. Molecular data combined with morphology support the division of traditionally delimited C. microcalyx into C. acutiloba, C. microcalyx and C. minor, corresponding to well-delimited nrDNA lineages. Furthermore, we propose to combine C. microcalyx subsp. paradoxa at the species level. A group of specimens previously thought to belong to Cymbalaria microcalyx constitute a well-defined phylogenetic and morphological entity and are described here as a new species, Cymbalaria spetae. Cymbalaria longipes is non-monophyletic, but characterized by being glabrous and diploid, unlike other eastern species. The nrDNA data suggest at least two dispersals from the mainland to the Aegean Islands, potentially facilitated by marine regressions.
