Taxonomic revision of the genus <i>Logfia</i> (Asteraceae, Gnaphalieae) in the Mediterranean region

A taxonomic revision of the West Palaearctic species of the genus Pales Robineau-Desvoidy is presented and the identity of the genus is defined and discussed. Pales abdita sp. nov. from some localities in the Mediterranean region and Pales marae sp. nov. from Sardinia are described, illustrated and compared with similar species. A key to the ten known West Palaearctic species of Pales is presented. The rare genus Schembria Rondani is suggested as the possible sister-group of Pales and the male genitalia of the only known species, S. meridionalis Rondani, are figured for the first time.

Woolly Mammoth

Pigmy elephants inhabited the islands from the Mediterranean region during the Pleistocene period but became extinct in the course of the Holocene. Despite striking distinctive anatomical characteristics related to insularity, some similarities with the lineage of extant Asian elephants have suggested that pigmy elephants could be most probably seen as members of the genus Elephas . Poulakakis et al. (2006) have recently challenged this view by recovering a short mtDNA sequence from an 800 000 year old fossil of the Cretan pigmy elephant ( Elephas creticus ). According to the authors of this study, a deep taxonomic revision of Cretan dwarf elephants would be needed, as the sequence exhibits clear affinities with woolly mammoth haplotypes. However, we point here many aspects that seriously weaken the strength of the ancient DNA evidence reported.

Diagnostic Key

AbstractA taxonomic revision of the lichenized species of the genus Omphalina in the Iberian Peninsula is presented, based upon fungal and lichen herbarium material, as well as on fresh collections. Relevant morphological and ecological features are discussed and a diagnostic key is provided. Four lichenized species, O. ericetorum, O. hudsoniana, O. meridionalis and O. velutina are recognized. A squamulose vegetative thallus (Coriscium-type) is present only in O. hudsoniana, while the other three species form a thallus of hyphal globules (Botrydina-type). Anatomical features of the vegetative thallus cannot be used to distinguish between these last three species. Whilst O. hudsoniana is known only from the montane belt of the Eurosiberian Region and O. meridionalis seems to restricted to the Mediterranean Region, living in more or less humid sites of the Supramediterranean belt, the other two species, O. ericetorum and O. velutina, are widespread.
