The Mediterranean black coral fauna includes type species of four antipatharian genera belonging to four different families, therefore phylogenetic studies hold great potential for enhancing systematics within the order. The analysis of six Mediterranean antipatharian species by means of nuclear sequence data of internal transcribed spacer (ITS1 and ITS2) rDNA confirms the separation into different families, as was previously noted on a morphological basis, with a clear distinction of the family Leiopathidae, whose position is supported by a unique number of mesenteries and lack of spines on thicker ramifications. The position of a newly recorded black coral species for the Mediterranean basin belonging to the genus Phanopathes is discussed. Antipathes dichotoma, the type species of the genus Antipathes, on which the order Antipatharia was based, does not group with other members of the family Antipathidae. Supporting a recent finding based on mitochondrial markers, this suggests a critical need for revision of the families that will be impacted by reassignment of this nomenclaturally important taxon.

The Malagasy genus Carphalea (Rubiaceae) consists of six species (C. angulata, C. cloiselii, C. kirondron, C. linearifolia, C. madagascariensis, C. pervilleana) of shrubs or small trees and is recognizable by a distinctly lobed calyx, 2(–4)-locular ovaries, each locule with several ovules on a rod-like stalk arising from the base of the locule, and indehiscent fruits. Carphalea linearifolia, rediscovered in 2010, has not previously been included in any Rubiaceae molecular phylogenetic studies. We re-investigated the monophyly of Carphalea using sequence data from chloroplast (rps16 and trnT-F) and nuclear (ITS and ETS) markers analysed with parsimony and Bayesian methods. Carphalea linearifolia forms a clade with C. cloiselii and the type species C. madagascariensis. This clade is sister to a clade consisting of the rest of the Carphalea species plus the genus Triainolepis. According to these results, the new genus Paracarphalea is here described to accommodate Carphalea angulata, C. kirondron, and C. pervilleana. The conservation status of Carphalea linearifolia is assessed as critically endangered according to IUCN criteria.

Anatomical Characters

ABSTRACT The assignment of species to the vetigastropod genus Solariella Wood, 1842, and therefore the family Solariellidae Powell, 1951, is complicated by the fact that the type species (Solariella maculata Wood, 1842) is a fossil described from the Upper Pliocene. Assignment of species to genera has proved difficult in the past, and the type genus has sometimes acted as a ‘wastebasket’ for species that cannot easily be referred to another genus. In the light of a new systematic framework provided by two recent publications presenting the first molecular phylogenetic data for the group, we reassess the shell characters that are most useful for delimiting genera. Shell characters were previously thought to be of limited taxonomic value above the species level, but this is far from the case. Although overall shell shape is not a reliable character, our work shows that shell characters, along with radular and anatomical characters, are useful for assigning species to genera. Sculpture of the early teleoconch (the region immediately following the protoconch) and the columella are particularly useful characters that have not been used regularly in the past to distinguish genera. However, even with the combination of all morphological characters used in this study (shell, radular and eye), a few species are still difficult to assign to genera and in such cases molecular systematic data are essential. In the present study, we discuss 13 genera—12 of which were recovered as well-supported clades in recent molecular systematic studies—and provide morphological characters to distinguish them. We describe several new taxa: Chonospeira n. gen. (referred to as ‘clade B’ in previous molecular systematic studies), Phragmomphalina n. gen. (Bathymophila in part in molecular systematic studies) and Phragmomphalina vilvensi n. sp. (type species of Phragmomphalina n. gen.). We synonymize Hazuregyra Shikama, 1962 with Minolia A. Adams, 1860, Minolia subangulata Kuroda & Habe, 1952 with Minolia punctata A. Adams, 1860 and M. gemmulata Kuroda & Habe, 1971 with M. shimajiriensis (MacNeil, 1960). We also present the following new combinations: Bathymophila bairdii (Dall, 1889), B. dawsoni (Marshall, 1979), B. regalis (Marshall, 1999), B. wanganellica (Marshall, 1999), B. ziczac (Kuroda & Habe in Kuroda, Habe & Oyama, 1971), Chonospeira nuda (Dall, 1896), C. iridescens (Habe, 1961), C. ostreion (Vilvens, 2009), C. strobilos (Vilvens, 2009), Elaphriella corona (Lee & Wu, 2001), E. diplax (Marshall, 1999), E. meridiana (Marshall, 1999), E. olivaceostrigata (Schepman, 1908), E. opalina (Shikama & Hayashi, 1977), Ilanga norfolkensis (Marshall, 1999), I. ptykte (Vilvens, 2009), I. zaccaloides (Vilvens, 2009), Minolia shimajiriensis (MacNeil, 1960), M. watanabei (Shikama, 1962), Phragmomphalina alabida (Marshall, 1979), P. diadema (Marshall, 1999), P. tenuiseptum (Marshall, 1999), Spectamen euteium (Vilvens, 2009), S. basilicum (Marshall, 1999), S. exiguum (Marshall, 1999) and S. flavidum (Marshall, 1999).

AbstractThe larvae of Anischia Fleutiaux and Perothops Laporte are described. Cladistic analyses based on adult and larval morphology, as well as CO1 sequence data, place both genera in the Eucnemidae clade within the Elateroidea (sensu stricto). The subfamily Anischiinae Fleutiaux, 1936 is placed in the family Eucnemidae in a clade containing the more derived eucnemid subfamilies (Melasinae, Eucneminae and Macraulacinae), while Perothops and Phyllocerus Lepeletier & Serville represent subfamilies basal to the remaining eucnemid taxa. The genus Afranischia Basilewsky, 1955 is synonymized with Anischia Fleutiaux, 1896, and Anischia boliviana Fleutiaux is selected as the type species of the latter. Three new species are described: Anischia bicolor (New Caledonia), Anischia kuscheli (New Caledonia) and Anischia monteithi (NE Australia), and Anischia stupenda Fleutiaux, 1897 is recorded from Australia. Anischia crassicornis Champion, 1897 is synonymized with Anischia mexicana Fleutiaux, 1896. One new combination is made, Anischia ruandana (Basilewsky, 1955).

Generic Relationships

The Amaranthaceae-Chenopodiaceae alliance has been the focus of several phylogenetic studies, but major questions concerning the internal relationships of Amaranthaceae still remain unanswered. This study aims to test the monophyly of the subfamily Gomphrenoideae and to examine the generic relationships within this group. Parsimony and Bayesian analyses of trnL-F and rpl16 show that the subfamily Gomphrenoideae is monophyletic. The clade of Gomphrenoideae represents a large and diverse radiation of the Amaranthaceae in the New World. Unilocular anthers are a morphological synapomorphy for Gomphrenoideae that was derived from bilocular anthers. Three major clades are resolved: the Gomphrenoids, the Alternantheroids, and the Iresinoids, which are largely supported by pollen morphology. The Iresinoid clade is sister to Alternantheroids plus Gomphrenoids, rendering metareticulate pollen as the synapomorphy for the latter two clades. Tribes and subtribes delimited by androecium and inflorescence characters are poly- or paraphyletic. Several genera are monophyletic including the large genus Alternanthera, whereas Gomphrena is polyphyletic. Irenella and Woehleria are resolved within Iresine whereas Blutaparon and Lithophila fall within the polyphyletic Gomphrena. The trnL-F and rpl16 sequence data are the most variable chloroplast regions examined to date for the family and are highly effective in resolving relationships in Amaranthaceae.

Subjective Synonym

The type species of three little-known Tertiary bryozoan genera have been examined and redescribed. Victorian Bitectipora lineata, previously the only recognised species of Bitectiporidae, is shown to be related to a present-day New Zealand species which may now also be included in Bitectipora. Further, the family Bitectiporidae MacGillivray, 1895 is here considered to be a senior subjective synonym of Hippoporinidae Brown, 1952. Schizosmittina, a French Miocene genus, is confirmed to be congeneric with a suite of Holocene Australasian species and removed from the Smittinidae to the Bitectiporidae. However, on the basis of ovicellular morphology, both families are considered to be closely related. The scarcely used superfamily taxon Smittinoidea is re-established for those families with 'smittinid' ovicells (in contradistinction to 'schizoporellid' ovicells). The genus Stephanollona, based on a French Miocene species, is recognised to be a senior subjective synonym of Brodiella (Phidoloporidae), which includes present-day species from Australasia, South Africa, southern South America, Madeira, south-west Britain and the Mediterranean.

The monotypic genus Neoaquastroma (Parabambusicolaceae, Pleosporales) was introduced for a microfungus isolated from a collection of dried stems of a dicotyledonous plant in Thailand. In this paper, we introduce two novel species, N.bauhiniae and N.krabiense, in this genus. Their asexual morphs comprise conidiomata with aseptate and hyaline conidia. Neoaquastromabauhiniae has ascomata, asci and ascospores that are smaller than those of N.krabiense. Descriptions and illustrations of N.bauhiniae and N.krabiense are provided and the two species compared with the type species of the genus, N.guttulatum. Evidence for the introduction of the new taxa is also provided from phylogenetic analysis of a combined dataset of partial LSU, SSU, ITS and tef1 sequence data. The phylogenetic analysis revealed a distinct lineage for N.bauhiniae and N.krabiense within the family Parabambusicolaceae.

The life cycle of Eucheilota medusifera ? (Torrey, 1902), comb. nov. [=Campalecium medusiferum] (Cnidaria: Hydrozoa: Lovenellidae) from the Bay of Biscay (northeastern Atlantic), including a description of the adult medusa

The life cycle of Campalecium medusiferum ? Torrey, 1902 (Cnidaria: Hydrozoa) was traced in the laboratory from material collected from the Bay of Biscay (northeastern Atlantic). Both newly released and one-month-old male medusae with fully-grown gonads are described, with remarks on their biology and behaviour. The adult medusa corresponds with the diagnosis of Eucheilota McCrady, 1859, and the species is reassigned from Haleciidae Hincks, 1868 to Lovenellidae Russell, 1953. The genus Campalecium Torrey, 1902 can be considered valid only if the characters of a species with Halecium-like polyps and Eucheilota-like medusae are considered of generic significance. Instead, the species studied here is assigned to Eucheilota, as E. medusifera ? (Torrey, 1902) (comb. nov.), and Campalecium is considered a likely synonym of that genus. The medusa is different from Lovenella cirrata (Haeckel, 1879), type species of the genus Mitrocomium Haeckel, 1879, previously suggested to have been linked to the same hydroid in the Mediterranean. A supposed connection between medusae of L. cirrata and Halecium-like hydroids cannot be supported, and assigning these hydroids to Mitrocomium is rejected. Future studies may prove that Halecium-like hydroids release medusae of diverse genera within the family Lovenellidae.

AbstractThe continental shelf edge of the NW Gulf of Mexico supports dozens of reefs and banks, including the West and East Flower Garden Banks (FGB) and Stetson Bank that comprise the Flower Garden Banks National Marine Sanctuary (FGBNMS). Discovered by fishermen in the early 1900s, the FGBs are named after the colourful corals, sponges and algae that dominate the region. The reefs and banks are the surface expression of underlying salt domes and provide important habitat for mesophotic coral ecosystems (MCE) and deep coral communities to 300 m depth. Since 2001, FGBNMS research teams have utilized remotely operated vehicles (e.g. ‘Phantom S2’, ‘Mohawk’, ‘Yogi’) to survey and characterize benthic habitats of this region. In 2016, a Draft Environmental Impact Statement proposed the expansion of the current sanctuary boundaries to incorporate an additional 15 reefs and banks, including Elvers Bank. Antipatharians (black corals) were collected within the proposed expansion sites and analysed using morphological and molecular methods. A new species, Distichopathes hickersonae, collected at 172 m depth on Elvers Bank, is described within the family Aphanipathidae. This brings the total number of black coral species in and around the sanctuary to 14.

Close Relatives

Based on a previous molecular phylogenetic analysis, Cryptantha, an herbaceous plant genus of the family Boraginaceae, subtribe Amsinckiinae, was split into five genera: Eremocarya, Greeneocharis, Johnstonella, Oreocarya, and a reduced Cryptantha, the last in two separate clades. As a result of this study, Johnstonella was expanded to 13 species and 15 minimum-rank taxa, these formerly classified in Cryptantha s.l. More recent analyses of this complex, with an increased sample size and high-throughput sequence data, indicate that four additional Cryptantha species not previously sampled—C. albida, C. mexicana, C. texana—plus what was originally identified as C. hispida nest within Johnstonella with strong support. However, the identity of C. hispida used in this analysis is now in doubt. The material used likely represents a new species, in the process of being investigated. Two additional species not sequenced to date—C. geohintonii and C. gypsites—are clearly close relatives of C. albida and C. mexicana, based on morphological similarity. In order to maintain monophyly of genera, we here make new combinations in transferring four of these species from Cryptantha to Johnstonella, with the new combinations Johnstonella albida, J. geohintonii, J. gypsites, and J. mexicana. We delay the transfer of Cryptantha texana to Johnstonella because of its morphological similarity to other species that clearly nest within Cryptantha s.s. These same molecular phylogenetic studies may also support the transfer of two previously recognized Johnstonella species—J. echinosepala and J. micromeres—to Cryptantha, one to each of two separate clades. Additional phylogenetic studies focusing on some of these taxa are needed to confirm the position of these latter three species and the possible recognition of a new genus in the complex.

Two New Species

Two new genera and two new species of black corals are recognized in the family Aphanipathidae. The new genus Anozopathes, with the species A. hawaiiensis sp. nov. and A. palauensis, sp. nov. is characterized by a sparsely and irregularly branched corallum with relatively long branches which can be straight, curved or crooked. The genus Aphanostichopathes, with the type species Cirripathes paucispina Brook, is characterized by an unbranched corallum with a long, curved stem with loose distal coils. Mitochondrial DNA data (nad5-IGR-nad1 for Anozopathes and cox3-cox1 for Aphanostichopathes) indicate that both taxa are related to the genera Aphanipathes, Phanopathes and Acanthopathes in the family Aphanipathidae, and morphologically they both share the characteristic of having spines with distinct conical tubercles. The two new species of Anozopathes are separated primarily by differences in colony growth form and in the size and shape of the skeletal spines. Species of Aphanostichopathes are separated primarily by differences in the size and shape of the spines and by size and density of the tubercles on the surface of the spines.
