Based on a combination of morphological and genetic data, geographically isolated populations of Pygopus from northeastern Queensland, formerly referred to Pygopus lepidopodus (Lacépède), are herein described as a new species. Pygopus robertsi sp. nov. can be diagnosed from its congeners by a suite of scalation characters, including fewer keeled dorsal scales, presence of a single continuous row of supracilaries and a lower number of midbody scale rows. It is also deeply divergent genetically from samples of Pygopus lepidopodus from southern Australia. The known distribution of Pygopus robertsi sp. nov. is similar to that of a number of taxa centred upon relatively dry ecotonal habitats at the western edge of the rainforest blocks of north-eastern Queensland. Additional samples and systematic work will be required to examine the evolutionary divergence of apparently isolated populations of the new species, and the significance of considerable genetic and morphological diversity within remaining populations of Pygopus lepidopodus from south-eastern and southern Australia.

Field studies of the inselberg flora of north-eastern Brazil have resulted in the discovery of much greater morphological diversity of the genus Ameroglossum, than previously envisaged. These enigmatic plants are endemic to isolated rock outcrops, which have long been surrounded by unsuitable habitat. The morphological forms are geographically isolated and stable in cultivation when grown under similar conditions. We here provide detailed descriptions of the two previously known species and propose an additional seven new species in the genus. A taxonomic revision of the genus, including an identification key is provided. We hypothesize that the evolution of this genus is driven by the diversity of their hummingbird pollinators. Due to the threatened nature of inselberg habitats and the small populations found for most taxa, the species described here are likely to be under threat and in need for formal redlisting.

A New Species

Nine currently accepted species of the genus Sargassum (Phaeophyceae) have been recorded from the Mediterranean Sea: S. acinarium, S. desfontainesii, S. flavifolium, S. furcatum, S. hornschuchii, S. muticum, S. ramentaceum, S. trichocarpum and S. vulgare. Two of them, S. desfontainesii and S. furcatum, are Atlantic species, the Mediterranean range of which is restricted to the Alboran Sea, close to the Strait of Gibraltar. Three species, S. hornschuchii, S. ramentaceum and S. trichocarpum are endemic to the Mediterranean. The presence of S. flavifolium in the Mediterranean, a north-eastern Atlantic species, is at least in part based upon a misidentification and therefore requires confirmation. A taxon collected near Algiers and Annaba (Algeria), here referred to as ‘Sargassum sp. from Algeria’, although sharing most characters with S. flavifolium, also presents some distinctive characters. In the absence of genetic data, confirming or not its taxonomic value, and in the lack of studies on the herbaria containing the types of many species currently considered as synonyms of S. flavifolium, but which are possible candidates for accommodating the Algerian specimens, the authors prefer a conservative approach. They do not describe a new species, which would be premature, but draw attention to a taxon which may be more widely distributed in the Mediterranean rather than solely along the Algerian coasts.

Abstract Four new species of the eutheiine genus Paraneseuthia Franz, 1986 are described: P. luzonica sp. nov. (the Philippines), P. kaibesariana sp. nov. (Indonesia: Kai Besar Is.), P. tanimbariana sp. nov. (Indonesia: Yamdena Is.), and P. morobensis sp. nov. (Papua New Guinea). Externally, these species share many characters with members of the SE Asian, Sundaland group within the genus. However, male genitalic structures of some of them resemble aedeagi of Australian Paraneseuthia, supporting previous phylogeographic hypotheses that assumed the origins of both north-eastern (Far Russian and Japanese) and south-eastern (Australian and Melanesian) Paraneseuthia from a Sundaland ancestor. The aedeagus of P. morobensis sp. nov. shows intermediary shape and structures between those of P. quadrifoveata Jałoszyński, 2010 of Borneo, Sabah, and that of P. levigata Jałoszyński, 2010 of eastern Papua New Guinea. The aedeagus of P. tanimbariana sp. nov., in turn, shows a striking similarity to that of the northern Australian P. angustifurculata Jałoszyński, 2013 and other species known to occur in Australia. The male genitalia of P. luzonica sp. nov. (the first species discovered in the Philippines), and especially of P. kaibesariana sp. nov., add unique features to the already known, great morphological diversity of the SE Asian members of Paraneseuthia that occupy the presumable evolutionary cradle of this genus.

In studies carried out off the north-eastern and south-eastern coast of Brazil, three species ofProsphaerosylliswere found:P. isabellae, which was already recorded for Brazilian waters;P. xarifae, a newly recorded species for the area; and P.brachycephalasp. nov., a new to science species.Prosphaerosyllis brachycephalasp. nov., is characterized by having swollen anterior part of the body, prostomium retractable within the peristomium and anterior segments, short antennae, short peristomial and dorsal cirri, and falcigers with short, unidentate blades throughout. All these species are herein described and compared to the most similar congeners.
