A New Species

Taxonomic diversity of Neotropical Rochefortia is not completely assessed at present. We report the existence of a new species: Rochefortia barloventensis sp. nov., distributed across multiple islands of the Lesser Antilles. We provide a morphological description, a molecular diagnosis and a botanical illustration. Specimens belonging to the new species were previously assigned to Caribbean R. cuneata or to South American R. spinosa because of morphological similarity. Molecular sequence data shows a clear delimitation of the new species from all other species of Rochefortia justifying the recognition of a novel taxon.

AbstractThe new species Aspicilia malvinae is described from the Falkland Islands. It is the first species of Megasporaceae to be discovered on the islands and only the seventh to be reported from South America. It is distinguished from other species of Aspicilia by the unusual secondary metabolite chemistry (hypostictic acid) and molecular sequence data. The collections of the new species support two lichenicolous fungi: Endococcus propinquus s. lat., which is new to the Falkland Islands, and a new species of Sagediopsis with small perithecia and 3-septate ascospores c. 18–20 × 4–5 μm, which is described here as S. epimalvinae. A total of 60 new DNA sequences obtained from species of Megasporaceae (mostly Aspicilia) are also introduced.

A New Species

Xanthoparmelia(Parmeliaceae, Ascomycota) is the most species-rich genus of lichen-forming fungi. Species boundaries are based on morphological and chemical features, varying reproductive strategies and, more recently, molecular sequence data. The isidiateXanthoparmeliamexicanagroup is common in arid regions of North and Central America and includes a range of morphological variation and variable secondary metabolites – salazinic or stictic acids mainly. In order to better understand the evolutionary history of this group and potential taxonomic implications, a molecular phylogeny representing 58 ingroup samples was reconstructed using four loci, including ITS, mtSSU, nuLSU rDNA and MCM7. Results indicate the existence of multiple, distinct lineages phenotypically agreeing withX.mexicana.One of these isidiate, salazinic acid-containing lineages is described here as a new species,X.pedregalensissp. nov., including populations from xerophytic scrub vegetation in Pedregal de San Angel, Mexico City.X.mexicanas. str. is less isidiate thanX.pedregalensisand has salazinic and consalazinic acid, occasionally with norstictic acid; whereasX.pedregalensiscontains salazinic and norstictic acids and an unknown substance. Samples from the Old World, morphologically agreeing withX.mexicana, are only distantly related toX.mexicanas. str. Our results indicate thatX.mexicanais likely less common than previously assumed and ongoing taxonomic revisions are required for isidiateXanthoparmeliaspecies.

The exploration of Earth's biodiversity is an exciting and ongoing endeavour. Here, we report a new species of seadragon from Western Australia with substantial morphological and genetic differences to the only two other known species. We describe it as Phyllopteryx dewysea n. sp. Although the leafy seadragon ( Phycodurus eques ) and the common seadragon ( Phyllopteryx taeniolatus ) occur along Australia's southern coast, generally among relatively shallow macroalgal reefs, the new species was found more offshore in slightly deeper waters. The holotype was trawled east of the remote Recherche Archipelago in 51 m; additional specimens extend the distribution west to Perth in 72 m. Molecular sequence data show clear divergence from the other seadragons (7.4–13.1% uncorrected divergence in mitochondrial DNA) and support a placement as the sister-species to the common seadragon. Radiographs and micro-computed tomography were used on the holotype of the new species and revealed unique features, in addition to its unusual red coloration. The discovery provides a spectacular example of the surprises still hidden in our oceans, even in relatively shallow waters.

Philophylla millei, n. sp., from New Caledonia is described and its relationship analyzed. This species was recorded previously as Anastrephoides sp. based on a single female, which closely resembles the eastern Palaearctic species Anastrephoides matsumurai Shiraki. Whether this similarity reflects the close relationship of these species or a case of convergent evolution was examined using morphology and molecular data. We examined both male and female specimens of the New Caledonian trypetine species and sequenced the mitochondrial 16S ribosomal RNA gene of this species and related trypetine species. This new species is a member of the genus Philophylla Rondani based both on the female postabdominal structure as well as DNA sequence data.

A new species of Argiope Audouin 1826, A. hoiseni new species is described from Perak and Selangor, Peninsular Malaysia based on morphology and DNA information of the mitochondrial (16S rRNA, COI and COII) and nuclear-encoded (H3A, 18S rRNA) molecular markers. Epigynal structure suggested Argiope hoiseni to be similar to A. jinghongensis Yin, Peng & Wang 1994, A. luzona (Walckenaer 1841), A. pulchella Thorell 1881 and A. taprobanica Thorell 1887. Molecular sequence data including the new species inferred that it is monophyletic with an intraspecific variation of 0.87–3.59 % based on the 16S+COI+COII+H3A dataset. Phylogenetic analyses also revealed insights into the evolutionary lineages of Argiope species in Southeast Asia as well as corroborated recent taxonomic changes and species synonymies associated with Argiope. Two new distribution records were also reported for A. chloreis Thorell,1877 and A. doleschalli Thorell, 1873 in Peninsular Malaysia.

Two new genera and twelve new species of Graphidaceae are described from Puerto Rico. The two new genera, Borinquenotrema and Paratopeliopsis, are based on a combination of molecular sequence data and phenotype characters. Borinquenotrema, with the single new species B. soredicarpum, features rounded ascomata developing beneath and persistently covered with soralia and with an internal anatomy reminescent of Carbacanthographis; it is close to the  tribe Ocellularieae. Paratopeliopsis, including the single new species P. caraibica, resembles a miniature Topeliopsis but differs in the distinctly farinose thallus and the small, brown ascospores; it is not closely related to the latter genus but belongs in tribe Thelotremateae. The other ten new species belong in the genera Acanthotrema, Clandestinotrema, Compositrema, Fissurina, Ocellularia, and Thalloloma. Acanthotrema alboisidiatum is closely related to A. brasilianum but differs in the short, white isidia resembling insect eggs. Clandestinotrema portoricense has a unique ascospore type with a longitudinal septum only in the proximal cell. Compositrema borinquense resembles a species of Stegobolus but belongs in Compositrema based on sequence data, and is characterized by ascomata with a unique columella composed of thick, irregularly radiating strands. The second new species in this genus, C. isidiofarinosum, differs by its ecorticate, farinose thallus with scattered, corticate isidia and by its small ascomata with inconspicuous columella. The three new species of Fissurina all have 3-septate ascospores and are otherwise characterized by an isidiate thallus and stellate, orange-yellow lirellae (F. aurantiacostellata), a verrucose thallus strongly encrusted with calcium oxalate crystals and white, irregularly branched lirellae (F. crystallifera), and myriotremoid ascomata arranged in short lines (F. monilifera). Ocellularia portoricensis belongs in the core group of Ocellularia and differs from O. cavata in the white medulla and the larger ascospores becoming brown, whereas O. vulcanisorediata produces prominent soralia and immersed ascomata with apically carbonized excipulum and columella and small, transversely septate, hyaline ascospores; it is closely related to O. conformalis. Finally, Thalloloma rubromarginatum resembles T. haemographum in the brownish lirellae with bright red margin but differs from that and other species in the corticate thallus and the norstictic acid chemistry. The new combination Ampliotrema rimosum (Hale) Mercado-Díaz, Lücking & Parnmen is also proposed. Considering the current biodiversity knowledge on this family, the high level of endemism observed in other groups of organisms in the island, and the relatively high number of Graphidaceae described, it is highly likely that at least some of these new taxa are endemic to the island. This view is further supported by the unique features of several of the new species, representing novel characters in the corresponding genera.

The formerly monotypic taxon, Hyalopale bispinosa Perkins 1985 (Chrysopetalinae), is comprised of a cryptic species complex from predominantly tropical embayments and island reefs of the Western Atlantic and Indo-Pacific Oceans. Hyalopale species are of meiofaunal size (length: 1−2.8mm), but considered non-interstitial, with the majority of species inhabiting a singular habitat of shallow littoral zones among algae and epifauna overlying sediments in rubble. Hyalopale adults exhibit notochaetal fans characterized by the presence of lateral and midline notochaetal spines. Species of Hyalopale can be distinguished by the shape of glass-like notochaetal paleae and the number of densely stacked ribs. Hyalopale bispinosa forms a western and eastern Atlantic species complex, comprising the type species, Hyalopale bispinosa s.s., a comparatively larger form with the highest number of notochaetal paleael ribs from Florida, and Hyalopale cf. bispinosa, from the western and eastern Mediterranean, a smaller form with a similar notochaetal morphology to the latter. Unfortunately, no molecular sequence data is available for Hyalopale bispinosa s.s. Five new species are described, with molecular sequence data provided for three: Hyalopale leslieae sp. nov., a small form with a comparatively low number of paleal ribs, found from the Florida Keys to Belize, Caribbean Sea, H. zerofskii sp. nov. from southern California and Mexico, eastern Pacific and H. sapphiriglancyorum sp. nov., a distinctive species with the lowest number of paleael ribs, from Raja Ampat, Indonesia and the Great Barrier Reef, Queensland, western Pacific. Two other species are described from morphology alone: H. angeliensis sp. nov. from Dampier, Western Australia and Seychelle Islands, eastern Indian Ocean and H. furfuricula sp. nov. from the Red Sea and Mozambique, western Indian Ocean, possessing a unique paleal brow shape. While well supported as a clade, support for relationships within Hyalopale is low. Hyalopale cf. bispinosa (Mediterranean) was recovered as sister group to the remaining Hyalopale, with H. leslieae sp. nov. as sister to the Hyalopale Pacific clade, comprising H. zerofskii sp. nov. (eastern Pacific) and H. sapphiriglancyorum sp. nov. (western Pacific). Within Chrysopetalinae, Hyalopale and Paleanotus formed a clade that was the sister group to the other paleate chrysopetalids under maximum likelihood, though Paleanotus grouped with the other paleate forms under maximum parsimony. The adult morphology of Hyalopale species is compared with that exhibited in the larvae of Paleanotus species; based on these results, including possession of a shared notochaetal character, Hyalopale is considered to contain paedomorphic taxa.
