Sunamphitoe Spence Bate, 1857 is one of several ampithoid amphipod genera to be reasonably specific to its algal host. Sunamphitoe was recently shown to be a senior synonym of Peramphithoe Conlan & Bousfield, 1982 by both morphological and molecular phylogenetic analyses that included selected exemplars of both putative genera. Phylogenetic analysis considering all species of Sunamphitoe herein corroborates the validity of this synonymy and also delineates several morphological groups within the genus. Eight new species are descibed herein, Sunamphitoe angrox sp. nov., S. batavia sp. nov., S. dampierensis sp. nov., S. jonathani sp. nov., S. lehae sp. nov., S. mixtura sp. nov., S. naturaliste sp. nov., and S. stevesmithi sp. nov., all from Australia and New Zealand; the status of the problematic New Zealand species, Sunamphitoe aorangi is resolved.

A New Species

Abstract Nematodes of the genus Physaloptera are globally distributed and more than 100 species are known. Their life cycle involves insects, including beetles, cockroaches and crickets, as intermediate hosts. This study describes a new species of Physaloptera and reports molecular phylogenetic analyses to determine its relationships within the family Physalopteridae. Physaloptera amazonica n. sp. is described from the stomach of the caviomorph rodent Proechimys gardneri collected in the Amazon rainforest in the state of Acre, Brazil. The species is characterized by the male having the first and second pair of sessile papillae asymmetrically placed, lacking a median papilla-like protuberance between the third pairs of sessile papillae, differentiated by size and shape of the spicules, while females have four uterine branches. For both nuclear 18S rRNA and MT-CO1 gene-based phylogenies, we recovered Turgida sequences forming a clade nested within Physaloptera, thus making Physaloptera paraphyletic to the exclusion of Turgida, suggesting that the latter may have evolved from the former monodelphic ancestral state to a derived polydelphic state, or that some species of Physaloptera may belong to different genera. Relationships between most taxa within Physaloptera were poorly resolved in our phylogenies, producing multifurcations or a star phylogeny. The star-like pattern may be attributed to evolutionary processes where past simultaneous species diversification events took place. Physaloptera amazonica n. sp. formed an independent lineage, separately from the other species of Physaloptera, thus supporting the status of a new species. However, all molecular data suggested a closer relationship with other Neotropical species. In conclusion, we added a new species to this already largely diverse genus Physaloptera, bringing new insights to its phylogenetic relationships. Further analyses, adding more species and markers, should provide a better understanding of the evolutionary history of physalopterids.

Abstract Background Hyoscyamus, the largest genus in the tribe Hyoscyameae, harbors more than 20 species. Although the monophyly of Hyoscyamus is supported by both morphological and molecular phylogenetic studies, the delimitation of Hyoscyamus has been hotly debated in different classifications. Here, we report a new species of Hyoscyamus (Solanaceae) from Henan Province, China, and discuss the delimitation of Hyoscyamus. Results This species is morphologically similar to the known species of Hyoscyamus and its close related genus Archihyoscyamus, but can be distinguished by corolla 2-lipped, adaxial lip 3-lobed and much longer than abaxial lips, tube slender at base, and stamens 5, inserted on inner side of disk, free, obviously unequal, and exceeding corolla. Phylogenetic analysis based on four chloroplast markers including rbcL, ndhF, trnC-psbM and trnL-trnF, strongly suggested that the new species was sister to a monophyletic group containing all species of Hyoscyamus and Archihyoscyamus previously described. Conclusions Both the morphological observations and molecular phylogenetic analyses support the recognition of Hyoscyamus labiatus as a new species. Our study also showed that Archihyoscyamus should be a synonym of Hyoscyamus. The delimitation of Hyoscyamus is thus revised in our study.

A New Species

Colletotrichum has numerous host range and distribution. Its species are important plant pathogens, endophytes and saprobes. Colletotrichum can cause regular or irregular depressions and necrotic lesions in the epidermal tissues of plants. During this research Colletotrichum specimens were collected from Mengyin County, Shandong Province, China. A multi-locus phylogenetic analysis of ITS, GAPDH, CHS-1, ACT, TUB2, CAL and GS sequence data combined with morphology, revealed a new species and two known species, viz. C. mengyinense sp. nov., C. gloeosporioides and C. pandanicola, belonging to the C. gloeosporioides species complex. The new species is described and illustrated in this paper and compared with taxa in the C. gloeosporioides species complex.

The status of the genus Tricholomopsis (Agaricales) in New Zealand is reviewed. T. rutilans is a species described from the northern hemisphere and recorded from plantations of exotic Pinus radiata in New Zealand. Historical collections identified as T. rutilans were subjected to morphological and phylogenetic analysis. The results show that most of these collections refer to T. ornaticeps, originally described from New Zealand native forests. The presence in New Zealand of T. rutilans was not confirmed. Collections of Tricholomopsis from native forests and bush also include a newly described species, T. scabra, which is characterised by a distinctly scabrous pileus. The new species is phylogenetically and morphologically distinct but related to T. ornaticeps. T. ornaticeps and T. scabra are currently known only from New Zealand and the former has extended its habitat to include exotic conifer plantations.

Rubia hangii, a new species of Rubia sect. Oligoneura from Guangxi Province, China, is described and illustrated. The placement of this species within Rubia is assessed based on a molecular phylogenetic analysis and morphological comparisons with related species. The new species is morphologically similar to R. siamensis and R. falciformis, but differs from the two taxa in having membranous to thin papery leaf blade, margins flat , slender petiole (< 1 mm wide), ovate-lanceolate stipule, triangular corolla lobes, fruit glabrous, with 1 ovule often aborted and 1 mericarp developed, rarely with 2 mericarps. Molecular phylogenetic analyses suggested that R. hangii is closely related to R. argyi and R. pallida. Rubia hangii can be easily distinguished from R. argyi and R. pallida based on leaf and stipule arrangement, leaf shape, number of principal veins, inflorescence position and flower shape.

The enchytraeid fauna of three areas in Jeju Island (Korea) was studied, and comparative morphological and molecular taxonomic examinations (based on CO1, ITS and H3 sequences) were performed on nine samples collected in 2016. Twenty-two enchytraeid species were recorded and identified. The descriptions of two new species (Achaetamultisacculatasp. n.andFridericiafloriformissp. n.) are presented in this paper. The main diagnostic features ofA.multisacculatasp. n.are: three pairs of pyriform glands per segment, clitellum with two “baguette-like” packages of glands, dorsal blood vessel from VII, secondary pharyngeal glands absent, oesophageal appendages well developed, two pairs of preclitellar nephridia, the reproductive organs (except the spermathecae in V) shifted one segment forward. The main features ofF.floriformissp. n.are that they are large worms, have up to 2–4 chaetae in bundles, strong body wall, thick cuticle, five pairs of preclitellar nephridia, c-type coelomo-mucocytes sometimes with some refractile vesicles, chylus cells in XII–XV, sperm funnels approximately twice as long than wide, spermathecae with long ectal duct without glands, ampullae surrounded distally by about 9–12 sessile diverticula of varying size. Molecular phylogenetic analyses supported the morphological results and confirmed the status of the two new species.

Definition Of

Poecilia obscura, new species, is described from the Oropuche system, Trinidad. A mitochondrial DNA-sequence based molecular phylogenetic analysis revealed the status of the new species as a separate taxon. It is most closely related to the Common guppy, P. reticulata and to the recently described species, P. wingei. It can also be distinguished by morphometrics and gonopodial characteristics from these two species, although the ranges for all values overlap. A definition of the new species on morphology criteria alone is thus impossible. Therefore, P. obscura forms a cryptic species complex with the two other species. P. wingei is now unequivocally defined by the molecular phylogeny as a valid species. The three guppy species are included in the subgenus Acanthophacelus Eigenmann (1907), which is considered as generically different from all other taxa of the Poeciliinae sensu Parenti (1981).

AbstractFive new Helicopha species are described from New Caledonia: H. paniensis sp.n., H. amieuensis sp.n., H. einap sp.n., H. ramea sp.n. and H. dognyensis sp.n. The new species are all endemic to New Caledonia and described herein. Distributional data is included on maps for all eight New Caledonian Helicopha species. A key to the males of New Caledonian Helicophidae is presented. Phylogenetic analyses performed on morphological characters of the males of Helicophidae species show that the New Caledonia Helicopha are monophyletic, but the relationship between the Australian and New Caledonian Helicopha species is at present not fully understood. Analyzing with equally weighted characters leaves the Australian Helicopha as the sistergroup to the New Caledonian Helicopha. When characters are weighted using implied weights and concavity constant of 2, the New Zealand Zelolessica split the New Caledonian and Australian Helicopha, leaving Helicopha paraphyletic. The monotypic New Caledonian genus Briama is closely related to Helicopha in all results.
