A recent phylogenetic study revealed a close relationship between chiactine-bearing (family Achramorphidae, order Leucosolenida) and pugiole-bearing (order Baerida) calcaronean sponges as well as new putative taxa within Achramorphidae. In this study, we present a revision of chiactine-bearing sponges based on morphological re-examination of type material and recently collected specimens, in addition to new molecular data for the ribosomal 18S and C-region of the 28S. We provide re-descriptions for all known chiactine-bearing species, and further describe two new species from the Antarctic (Achramorpha antarctica sp. nov. and Megapogon schiaparellii sp. nov.) and two new species and a new genus from the Nordic Seas (Achramorpha ingolfi sp. nov. and Sarsinella karasikensis gen. nov. sp. nov.). The new phylogenetic reconstruction based on ribosomal 18S and C-region of the 28S confirms previous findings about the close relationship of some members of Baerida and the family Achramorphidae of the order Leucosolenida. However, new material and the addition of molecular data from the type species of both taxa would be required to formally propose changes at (sub-)ordinal levels within the classification of Calcaronean sponges.

AbstractThe new lichen genus Sergipea M. Cáceres, Ertz & Aptroot is described in the Roccellaceae, based on the new species Sergipea aurata M. Cáceres, Ertz & Aptroot from NE Brazil. The species was found in a remnant of Atlantic transition forest in Sergipe. It is similar in many respects to species of the genus Enterographa, but it is characterized by bright orange stromata, due to the presence of an anthraquinone, and a thallus with a somewhat byssoid hypothallus. Phylogenetically it is close to the genera Dichosporidium and Erythrodecton. The phylogenetic position of the generic type of Dichosporidium confirms the close relationship of the genus to Erythrodecton in the basal branch of the Roccellaceae. A new species of Enterographa is also described from NE Brazil. Enterographa rotundata E. L. Lima, M. Cáceres & Aptroot has solitary, round apothecia, which is unusual in this genus with mainly elongated apothecia or punctiform apothecia arranged in lines. It was found in Caatinga forest in Pernambuco.

The new genus Yanomamius n. gen. from Brazilian and Venezuelan Amazon is described, with three new species from Brazil: Y. franciscoi n. sp. (type species), Y. raonii n. sp., and Y. neblina n. sp. The enigmatic Venezuelan species described as Holothele waikoshiemi Bertani & Araújo, 2006 and presently included in Guyruita Guadanucci et al. (2007) is transferred to the new genus, making the new combination Y. waikoshiemi (Bertani & Araújo, 2006) n. comb. Yanomamius n. gen. is closely related with the schismatotheline genera Schismatothele Karsch, 1879 and Euthycaelus Simon, 1889 sharing as probable synapomorphies a group of short spines on the retrolateral distal tibia of male palp and the shape of bulb. They differ by the position of the spines in a compact group instead of in rows and by a tapering embolus. Females differ from Schismatothele and Euthycaelus by the spermathecae weakly sclerotized. A series of recent phylogenies based on molecular data suggested a close relationship between schimatothelines and psalmopoeines. The male tibia I of Yanomamius n. gen. species have a series of ridges or a single protuberance behind the tibial apophyses that resemble those of psalmopoeines and strengthen the idea of close relationship of the two subfamilies.

Sigmaxinella hipposiderus sp. nov. is described from morphological and molecular datasets, based on a single known specimen collected from the upper margin of a submarine canyon on the edge of the continental shelf, south-east of coastal Victoria (Tasman Sea), Australia. Morphologically, the species is clearly assigned to the genus Sigmaxinella, and preliminary molecular data (COI mt DNA) support the close relationship of this new species to other specimens attributed to Desmacellidae. This is the thirteenth species of Sigmaxinella and the seventh described for the Australian EEZ. Remarkably, 12 of the 13 known species are recorded predominantly from temperate or subantarctic Australian, New Zealand or South African waters, with only a single species described so far from the temperate Atlantic Ocean.

The nomenclature and identity of Chiropsalmus quadrigatus have been extensively confused. Originally described from Rangoon, Burma, based on an immature and badly damaged specimen, subsequent Philippine and Australian redescriptions do not match primary characters of the holotype. This has led to widespread messiness in identification and classification of this and related species. In order to clarify the nomenclature of the Chiropsalmus-type cubomedusae, a preliminary revision of the Chiropsalmidae is given. Chiropsoides quadrigatus comb. nov. is proposed, in order to reflect the close relationship of this taxon with Chiropsoides buitendijki, based on the shared character of linear-branching pedalia. A common Australian form, often attributed to Chiropsalmus quadrigatus, is herein described as a new genus and species, Chiropsella bronzie. This new form differs from other Chirodropida in having sessile, solid, smooth gastric saccules, whereas in other Chirodropida these structures are pendant whether they are smooth or branched. This new species is not dangerous to humans. Another form, Chiropsalmus alipes n. sp., is described from the Pacific coast of southern Mexico; this new species differs from others in having long, blade-like pedalia similar to those of the Carybdeida, only four tentacles at maturity per pedalium, each branching in a different direction, and a warty body; comments are made regarding its apparent relationship to the enigmatic Chiropsalmus zygonema. The recently described Chiropsalmus maculatus is moved to a new genus, Chirodectes in the family Chirodropidae.

The bocagei clade is a species complex of dendrobatid frogs evidenced from recent molecular systematic studies. This lineage is endemic to the eastern Andean slopes and adjacent Amazonian lowlands in southern Colombia, Ecuador and northern Peru. Herein, we analyze the taxonomy of the bocagei clade by means of qualitative and quantitative morphological characters and call parameters. We recognize and provide accounts for six species: Hyloxalus bocagei, H. faciopunctulatus, H. maculosus, H. sauli and two new species. We also provide phylogeographic data. We formally assign the name of Hyloxalus bocagei only to populations from the surroundings of Volcán Reventador (Provincia Napo, Ecuador). Additionally, we describe the tadpoles of Hyloxalus bocagei, H. maculosus, and two new species, plus vocalizations of H. bocagei, H. maculosus, H. sauli, and two new species. Morphological variation was estimated from 16 morphometric characters using multivariate analysis. Adults of the two new species were indistinguishable using quantitative and qualitatively morphological characters. Nevertheless, molecular data, call parameters (dominant frequency, note repetition rate), and tadpole morphology supported the recognition of these two species as cryptic taxa. A current phylogenetic tree using molecular characters of five species of the bocagei clade is also provided including the maximum likelihood (ML) phylogeny and a chronogram of the group. Our phylogeny confirms the close relationship of members of the bocagei clade with Andean relatives of Hyloxalus and recurrent dispersal events from the Andes to the Amazon Basin in the late Miocene (< 10 MYA). Our data also corroborate that the sister lineage of bocagei clade includes the Andean H. subpunctatus clade. We anticipate that further detailed morphological and molecular data will be necessary to reveal the existence of additional cryptic species within the bocagei clade.

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.

Based on morphological and molecular analyses, Pogostemon jaitapurensis is described and illustrated as a new species from Konkan region of Maharashtra, India. Present study added the molecular data of Indian endemic Pogostemon species of sect. Verticillatus and provide their phylogenetic placement. The bayesian and parsimony phylogenetic analyses conducted resolve Pogostemon into two clades, from them the new species belongs to Clade B and shows close relationship with species of sect. Verticillatus. A possible relationship between the new species and P. deccanensis and P. erectus, endemic to India, is also revealed by the phylogenetic analyses. Phylogenetically, the new species has been also placed in genus Pogostemon subg. Dysophyllus sect. Verticillatus. Sectional classification of these species is congruent with their phylogenetic positions.

With only three published reports, the genus Chroogomphus (Boletales, Gomphidiaceae) is poorly studied in Pakistan. During recent sampling events in Khyber Pakhtunkhawa province, Pakistan, several collections of Chroogomphus were made, representing undescribed taxa. Based on morphological and molecular data, two new species are described: Chroogomphus pakistanicus and C. pruinosus. We present a description and illustrations for both taxa. A molecular phylogenetic reconstruction, based on the internal transcribed spacer (ITS1–5.8S–ITS2) barcode region, shows that C. pakistanicus and C. pruinosus are placed in two different subgenera of Chroogomphus (subg. Chroogomphus and subg. Siccigomphus, respectively).

The biosystematic position of the Parallelia generic complex is reviewed and a revised generic classification of its component taxa is presented. Bastilla Swinhoe (= Xiana Nye, syn. nov., Naxia Guenée, syn. nov.) is identified as the most appropriate genus for a large number of these taxa, including the joviana-group, which is reviewed in detail, with description of two new species, B. nielseni, sp. nov. and B. binatang, sp. nov. Parallelia prouti Hulstaert, syn. nov. and P. cuneifascia Hulstaert, syn. nov. are recognised as junior synonyms of Bastilla vitiensis Butler and two newly described Tahitian taxa are transferred into the joviana-group. Larval host records are examined in relation to this new generic system and significant preference for the Euphorbiaceae is noted for several groups: Bastilla, Buzara Walker (= Caranilla Moore, syn. nov., another segregate from Parallelia) and an Australian group within Grammodes Guenée.
