Fishes from the Akkuyu Formation (Tithonian),Western Taurus,Turkey

Two fragmentary fishes are described from theUpper Jurassic (Tithonian) Akkuyu Formation of the Akseki region in the western Taurus (Turkey). Both are determinable, one as a caudal fin of an ichthyodectiform teleost, either Thrissops or Allothrissops, the other as a coelacanthid coelacanth, cf. Undina. This discovery extends the geographic range of these taxa and draw attention to the possibility of collecting a more extensive fish fauna from the region.     

Neolignans from the seeds of Prunus tomentosa (Rosaceae) and their chemotaxonomic interest

The role of neolignans in the chemotaxonomy of the genus Prunus has long been neglected. In this study, two new dihydrobenzofuran neolignans tomentosanans A (12) and B (14), together with 15 known neolignans, were isolated from the seeds of Prunus tomentosa. This is the first report on the occurrence of compounds 1–12, 14, 15 and 17 in the genus Prunus. The biosynthetic pathways of these neolignans are also summarized. Together, these neolignans represent a phytochemical fingerprint for P. tomentosa, which may be used for identification of Prunus species.

Male habitus photos and illustrations of male genitalia of the two new species and notes on allied species are also provided.     

Biphenyl and xanthone derivatives from the twigs of a Garcinia sp. (Clusiaceae)

The genus Garcinia is a well known rich source of bioactive xanthones and benzophenones. Some species of this genus also produce flavonoids and biphenyls as minor constituents. In this study, two new biphenyls, doitungbiphenyls A (1) and B (2), along with two biphenyls, schomburgbiphenyl (3) and nigrolineabiphenyl B (4); and four xanthones, 1,3,6-trihydroxy-8-isoprenyl-7-methoxyxanthone (5), morusignin K (6), 1,5-dihydroxyxanthone (7), and 1,7-dihydroxyxanthone (8), were isolated from the acetone extract of the twigs of a Garcinia sp. Their structures were characterized extensively by 1D and 2D NMR spectroscopy and HR-EI-MS. The cytotoxicity of the two new biphenyls against the oral cavity cancer (KB) and the breast cancer (MCF7) cell lines was also evaluated.     

New species and new combinations in Briquetia and Hochreutinera,and a discussion of the Briquetia generic alliance (Malvaceae)

Two new species ofBriquetia,B. sonorae andB. inermis, are described from northern Mexico, and another species that ranges from Mexico to Bolivia is transferred into the genus asB. spicata. The genus (previously known as monotypic, Paraguayan-Brazilian) is thereby enlarged from one species to four, and its geographical and morphological limits are greatly expanded. Also, a Mexican species ofAbutilon is transferred toHochreutinera, asH. amplexifolia, enlarging that genus from one to two species. On the basis of this new information, the limits of the informalBriquetia alliance are reconsidered; it is considered to include onlyBriquetia, Dirhamphis, andBatesimalva.     

Chemical constituents from the leaves of Zanthoxylum nitidum (Roxb.) DC

Twelve compounds were isolated from the ethyl acetate soluble portion of the 70% hydroalcoholic extract from the leaves of Zanthoxylum nitidum (Roxb.) DC. All of the compounds were determined on the basis of UV, IR, NMR and MS and comparison with literature. Among them, compounds 4, 7, 10 and 12 were first acquired from Rutaceae, compound 2 was isolated from the genus of Zanthoxylum for the first time and compounds 1, 3, 6, 9, 11 were isolated from Z. nitidum for the first time. Our present study exhibited the taxonomic relationships between Z. nitidum and other species in the same genus; those between Rutaceae and other families. Furthermore, we have summarized the chemotaxonomic significance of these compounds in Rutaceae and Zanthoxylum.     

Correllia (Compositae: Peritylinae) : A new monotypic genus from southern Chihuahua,Mexico

A new genus,Correllia, and its single species,C. montana, are described from Sierra Mohinora in southwestern Chihuahua, Mexico. The genus belongs in subtribe Peritylinae (Compositae tribe Helenieae) and appears to be most closely related toPerityle.     

A new genus and species of the subtribe Aolina (Hemiptera: Cicadidae: Dundubiini) from Vietnam,with discussion on the taxonomic positions of Meimuna-like genera and species groups

A new cicada genus, Cantata Lee & Pham gen. nov., is erected in the subtribe Aolina Boulard, 2012, with the designations of Cantata phiaoacensis Lee & Pham sp. nov. as its type species. This new genus is morphologically similar to Meimuna Distant, 1905 but distinguished from Meimuna mainly by the absence of the extended base of uncus, the presence of the basal lobe of male pygofer, the shape of the uncal lobes, and the presence of the fore wing infuscations. Cantata phiaoacensis Lee & Pham sp. nov. is described from Phia Oac – Phia Den National Park, Cao Bang province in northern Vietnam. A distribution map and biological data for Cantata phiaoacensis are provided. A key to the genera and the species groups of Aolina is provided.
