Monoterpenoid glucoindole alkaloids and iridoids from Pterocephalus pinardii.

A new secondary metabolite, pterocephaline, along with the known cantleyoside, 7α‐morroniside, 3β,5α‐tetrahydrodesoxycordifoline lactam, 5S‐5‐carboxyvincoside, sweroside, and loganin have been isolated from the aerial parts of P. pinardii (Dipsacaceae). Moreover, cantleyoside‐methyl‐hemiacetal and cantleyoside‐dimethyl‐acetal were obtained as seco‐iridoid artifacts. The structures were elucidated by extensive spectroscopic methods including 1D‐(1H, 13C and TOCSY) and 2D‐NMR (DQF‐COSY, HSQC and HMBC). Monoterpenoid glucoindole alkaloids were encountered for the first time in Dipsacaceae family. Copyright

Revision of the species of the Merodon nanus group (Diptera: Syrphidae) including three new species

The nanus group of the genus Merodon Meigen (Diptera, Syrphidae) is revised, yielding an illustrated key, a discussion of taxonomic characters and morphological diagnosis for the five species of this group. Three new cryptic species are described, Merodon kopensis Vujić et Hayat sp. n., M. neonanus Vujić et Taylor sp. n. and M. rasicus Vujić et Radenković sp. n. New diagnostic characters are given for M. nanus Sack and M. telmateia Hurkmans. In addition, environmental profiles for each investigated species have been defined and compared, and maps of distribution and richness created. Niche dissimilarity was found for each species. Eastern Anatolia and the southern Aegean region of Turkey are reported as the most species rich regions for the nanus group.

Helichrysum unicapitatum (Asteraceae), a New Species from Turkey

Helichrysum unicapitatum S.G. Şenol, Ö. Seçmen & B. Öztürk (Asteraceae) is described and illustrated from the SW province of Anatolia, Turkey. It grows on crystalline calcareous rocks between Evran Tepe and Karababa Tepe (1800–2300 m), situated within the Denizli Babadağ (Cadmus) Mountain Range. Helichrysum compactum seems to be its closest relative and their affinities are discussed based on morphological data and DNA sequences (nrDNA ITS and ETS).
