A new species, Helianthemum raskebdanae (H. sect. Helianthemum), is described from the maritime cliffs of north-eastern Morocco. It is easy to identify because of its glabrous and fleshy leaves with swollen reddish pulvinules at the petiole base, glabrous sepals with only minute stellate hairs on one margin, and large pinkish to purple petals. The new species is only known from three small, isolated sites, and it is here considered as Endangered (EN). Although it superficially resembles the Algerian H. maritimum, its combination of character-states is not found in the latter nor in any other related species of the section, i.e. H. apenninum, H. dianicum, H. scopulicola and H. virgatum, which warrants its recognition at the species rank. Micromorphological data support the proposed taxonomic treatment. Furthermore, nomenclatural types are designated for H. maritimum and H. maritimum f. albiflorum, two close Algerian relatives.

Centaurea ibn-tattoui is described and illustrated as a new species from north-eastern Morocco. Intermediate involucral bracts and leaves are the discriminant features separating it from other closely related taxa of C. sect. Acrocentron.

A new species of truffle, T.aztecorum, is described from central Mexico. Tuberaztecorum can be distinguished from other related Tuber species synoptically by a combination of morphological features including ascospore size, pellis cells with irregular thickness, cystidia, ascoma colour and associated host (Abiesreligiosa an endemic Abies species from central Mexico); sequence variation on the ITS rDNA also distinguishes T.aztecorum from related species. A phylogenetic analysis of the ITS rDNA demonstrates that T.aztecorum belongs to the Maculatum clade and is unique from other similar small, white-cream coloured Tuber species distributed in north-eastern Mexico such as T.castilloi and T.guevarai.

AbstractWe describe a new species of the genus Mantidactylus found during field inventories in the north-eastern rainforests of Madagascar. Mantidactylus salegy sp. n. reaches a snout-vent length of 45-50 mm, has evident dorsolateral ridges and whitish spots on the upper jaws (mainly in females). The vocal sacs in males are distinctly visible and paired subgular, without strongly inflatable areas recognizable between the blackish lateral skin flaps on the throat. This frog exhibits a mosaic of characters previously thought to be typical for either the subgenera Gephyromantis or Phylacomantis. Therefore, it is a crucial discovery towards better understanding of the relationships between the taxa included in these two subgenera, supporting previous molecular results which indicated their paraphyly. The call of M. salegy consists of a rapid series of 8-11 rattling notes emitted at 1000-3500 Hz. We also provide karyological data for M. salegy, and for several related species, M. granulatus, M. leucomaculatus, M. moseri, M. redimitus, M. zavona, and M. pseudoasper (attributed to the subgenus Phylacomantis) and M. luteus (subgenus Gephyromantis). In terms of general chromosome morphology and structure, NOR localisation and heterochromatin characteristics, M. salegy shows similarities to M. redimitus, M. zavona and M. leucomaculatus, all included within Phylacomantis. Our data confirm that NOR position is a phylogenetically informative character.

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.
