A new monotypic genus from southern Africa is described based on Thesium lineatum. Lacomucinaea lineata has a number of vegetative and floral morphological features that differ from Thesium and other members of Thesiaceae. An apparently unique feature of the plant is the presence of succulent, fusiform, terete leaves that are caducous, eventually leaving a persistent petiolar stub. The stem surface shows striations formed by cortical fibers inside raised ridges. Anatomically, this type of primary phloem fiber bundle also occurs in Osyridicarpos. A molecular phylogenetic analysis using nuclear ribosomal ITS and the chloroplast trnLF spacer for representatives of all genera in Thesiaceae showed that Lacomucinaea is sister to Osyridicarpos, further supporting this relationship suggested by stem anatomy characters. Recognizing this taxon as a distinct genus results in the genus Thesium being monophyletic. A key to all genera in Thesiaceae is provided.

Palearctic Species

The genus Asteralobia (Diptera, Cecidomyiidae, Asphondyliini, Schizomyiina) was erected by Kovalev (1964) based on the presence of constrictions on the cylindrical male flagellomeres. In the present study, we examine the morphological features of Asteralobia and Schizomyia and found that the male flagellomeres are constricted also in Schizomyiagaliorum, the type species of Schizomyia. Because no further characters clearly separating Asteralobia from Schizomyia were observed, we synonymize Asteralobia under Schizomyia. Molecular phylogenetic analysis strongly supports our taxonomic treatment. We describe five new species of Schizomyia from Japan, S.achyranthesae Elsayed & Tokuda, sp. n., S.diplocyclosae Elsayed & Tokuda, sp. n., S.castanopsisae Elsayed & Tokuda, sp. n., S.usubai Elsayed & Tokuda, sp. n., and S.paederiae Elsayed & Tokuda, sp. n., and redescribe three species, S.galiorum Kieffer, S.patriniae Shinji, and S.asteris Kovalev. A taxonomic key to the Japanese Schizomyia species is provided.

Molecular Phylogenetic Data

In this article, we research the phylogenetic position of the rare endemic banana, Musa huangbaioa, which was described only in Chinese journal in 1987. This banana was found at the foot of the Mount Emei in Sichuan Province and has remarkable morphological features, e. g., undulated petiole margins, ribbed fruits and irregular form of the seeds, which are rather unusual in the genus and distinguish it from all other species. In addition, due to its uncertain affinity, we researched the position of M. huangbaioa in the Musaceae family with the aid of molecular phylogenetic analysis of two marker sequences, nrITS and trnL–trnF. We found that this species belongs to the large and rather complicated group of Chinese bananas, M. basjoo–M. itinerans clade. According to the ITS data, M. huangbaioa is monophyletic with one M. basjoo specimen that was cultivated in Central America. Probably, this fact represents that this species can be modern hybrid with one of the genomes inherited from M. basjoo s. l. The whole group M. basjoo–M. itinerans, which M. huangbaioa belongs to, is well separated within the sect. Musa and could be prone to frequent hybridizations in the natural environment; it requires an additional research for more precise differentiation of the group.

AbstractElixia cretica T. Sprib. & Lumbsch is described as a new species from the mountains of western Crete. The second member of the previously monotypic genus and only the third member of the family Elixiaceae, it is distinguished by its surficial thallus, larger ascospores and corticolous habit. Molecular phylogenetic analysis based on a sequence of mitochondrial small subunit DNA confirms the position of the new species. We also report E. flexella from New Hampshire (USA) as new to eastern North America.

Boletus peckii, B. pulchriceps and B. roseopurpureus, which were originally described from North America, are characterized by a yellow tube layer that often bruises blue, a yellow reticulated stipe especially at the apex, firm yellow-tinged flesh that often turns blue when exposed, smooth spores and an interwoven trichodermic pileipellis. The phylogenetic positions of the three species are inferred by molecular phylogenetic analysis based on DNA sequences of four gene markers (ITS, nrLSU, tef1-α and rpb1). Both morphological features and molecular phylogenetic evidence indicate that these three boletes belong to Butyriboletus, and thus, should be transferred to the genus.

Gymnocarpium Dryopteris

The results of molecular phylogenetic studies based on the sequencing of matK gene and trnG-R intergenic spacer of the chloroplast DNA and analysis of the concatenated data of these loci of North Asian representatives of the Cystopteridaceae family are presented. In the genus Gymnocarpium, a dryopteris-clade was distinguished including species without glandular pubescence of fronds – Gymnocarpium dryopteris. Species having glandular pubescent fronds have formed the robertianum-clade (G. robertianum and G. fedtschenkoanum), and 2 subclades, including G. continentale, G. jessoense, and G. tenuipes. In the genus Cystopteris, the analysis confirmed the separation of C. montana from other Cystopteris species, and the separation of C. sudetica from the C. fragilis-complex. This advocate the recognition of monotypic genus Rhizomatopteris including Rh. montana (≡Cystopteris montana), and allows to recognize the section Khokhrjakovia (with C. sudetica) within the genus Cystopteris. This analysis did not allow to separate the species of the type subgenus Cystopteris (C. fragilis-complex) from each other.

Molecular phylogenetic analysis has demonstrated that the genus Gallinula is not monophyletic and comprises four major lineages. A review of the nomenclature of Gallinula shows that generic names are available for three lineages but that a fourth is as yet unnamed. A new monotypic genus, Paragallinula gen. nov., is described for Lesser Moorhen (Gallinula angulata Sundevall, 1850).

The article gives an overview of the small and archaic tribe Baphieae (Fabaceae, Fabales). The study is devoted to the taxonomic revision of the Baphieae tribe and and the phylogenetic relationships within the group based on the morphological, anatomical, palynological and molecular characteristics. It was carried out on the basis of studying about 5,000 herbarium leaves in 12 European and African botanical institutions. The study was performed using the morphological-geographical and molecular-phylogenetic analysis methods. The article provides information on the morphological features of the species included in the tribe, their geographical distribution and chemical composition. The results of phylogenetic analysis have been presented. According to it, it can be argued that the tribe Baphieae is a monophyletic group occupying a relatively isolated position among the subfamily of moths, based on morphological and molecular characteristics. The proposals for a new structure of the tribe have been made. The identification of several phylogenetic lineages within the tribe and the basal position of the genus Dalhousiea have been substantiated. Further studies have been identified.

Medlinella amphoroidea gen. et sp. nov. is described from the dorsal neck skin of loggerhead sea turtles (Caretta caretta). The presence of girdle septa, multiple copulae, and the marine epizoic habitat of Medlinella amphoroidea are characteristic features shared with many species in the similar Tripterion, Chelonicola, and Poulinea genera. The semi-lanceolate valve shape, the asymmetric valve face with distinct dorsal and ventral striae, and the volate pore occlusions distinguish Medlinella from these genera. Medlinella amphoroidea accounted for up to 50% of all diatom valves on the skin of examined loggerhead turtles. Examination of the type slides of Tripterion kalamensis and T. philoderma for comparative purposes revealed morphological features that were either insufficiently or incorrectly described in the original publications. Our observations confirm that T. philoderma lacks septa and therefore does not conform to the genus description of Tripterion. The description of cingulum structure in Tripterion kalamensis is amended to identify multiple porose copulae that are open at one end. While the description of Medlinella creates another monotypic genus within a group of similar marine epizoic genera, we feel the novel character state (volate occlusions) present in this taxon is significant. Clearly, however, further phylogenetic analysis of morphological, or the development of molecular characters in the group of similar genera is required.

A review of Austrocallerya J.Compton & Schrire and Pongamia Adans. (Leguminosae subfamily Papilionoideae) in Australia, and the description of a new monotypic genus, Ibatiria W.E.Cooper, is presented with the support of fresh, dried, spirit-preserved specimens, molecular phylogenetic analysis of plastid and nuclear data, and illustrations. Three Austrocallerya species are confirmed, described and distinguished for Australia. Two varieties of Pongamia pinnata (L.) Pierre are recognised; P. pinnata var. minor (Benth.) Domin is reinstated and is distinguished from var. pinnata by habitat, leaflet number and width, floral bract length and bracteole length. The new genus, Ibatiria, includes a single species, Ibatiria furfuracea W.E.Cooper, from Queensland’s Wet Tropics Bioregion. A second-step lectotype is designated for Pterocarpus australis Endl., and lectotypes are designated for Wisteria megasperma F.Muell. and Pongamia glabra var. minor Benth.

Molecular Phylogenetic Data

Phylogenetic position of the unique grass genus Coleanthus within the tribe Poeae s. str. is discussed based on molecular phylogenetic analysis of the marker sequences, ITS and trnL–trnF. Moreover, taxa more or less related to Coleanthus were involved in our study for the maximal accuracy of the molecular phylogenetic analysis. Subtribe Coleanthinae (=Puccinelliinae) is monophyletic according to both datasets, nuclear and chloroplast genes, that probably shows certain evolutionary distance from other Poeae s. str. We confirmed the results of previous morphological studies that placed Coleanthus close to the genus Phippsia but at the same time we have not found any evidences of the affinity between the genus Phippsia and the second putative ancestor, Deschampsia. The clade which contains Coleanthus and Phippsia occupies the sister position to all other genera of the subtribe Coleanthinae. The genus Phippsia produces hybrids with Puccinellia, ×Pucciphippsia, but the relationship obtained by our data is far more distant that was considered before from its morphological features. The genus Puccinellia forms a single monophyletic clade—sister to the genus Sclerochloa and former Colpodium s. l. (Paracolpodium, Catabrosella) which are monophyletic with Catabrosa. In partial contradiction to previous research (Soreng et al. 2015)—we found that the subtribe Coleanthinae is rather distant from two-chromosome grasses in ITS analysis though chloroplast genes show the sister position of the species from the 2-chromosome grasses group, Colpodium versicolor (2n = 4), to Coleanthinae. Also we detected multiple reticulation events in the tribe Poeae s. str. and some of them—within the subtribe Coleanthinae. This can explain an uncertain position of the two-chromosome grasses in relation to Coleanthinae.
