A molecularly based phylogeny reconstruction of mushroom corals (Scleractinia: Fungiidae) with taxonomic consequences and evolutionary implications for life history traits Naturalis
Gittenberger, A.; Reijnen, B.T.; Hoeksema, B.W..
The phylogenetic relationships of the Fungiidae, a family of predominantly free-living, zooxanthellate, reef corals, were studied by sequencing a part of the mitochondrial Cytochrome Oxidase I (COI) and the complete ribosomal Internal Transcribed Spacers (ITS) I & II of specimens from various locations in the Indo- West Pacific. Some sequences were retrieved by using fungiidspecific primers on DNA-extracts from parasitic gastropods living with these corals. The analyses were performed both including and excluding intraspecific variation to investigate the potential effect of saturation. Even though the present molecular phylogeny reconstructions largely reflect those based on morphological characters, there are some distinct differences. Three major...

A revised checklist of Nepticulidae fossils (Lepidoptera) indicates an Early Cretaceous origin Naturalis
Doorenweerd, C.; Nieukerken, E.J. van; Sohn, J.-C.; Labandeira, C.C..
With phylogenetic knowledge of Lepidoptera rapidly increasing, catalysed by increasingly powerful molecular techniques, the demand for fossil calibration points to estimate an evolutionary timeframe for the order is becoming an increasingly pressing issue. The family Nepticulidae is a species rich, basal branch within the phylogeny of the Lepidoptera, characterized by larval leaf-mining habits, and thereby represents a potentially important lineage whose evolutionary history can be established more thoroughly with the potential use of fossil calibration points. Using our experience with extant global Nepticulidae, we discuss a list of characters that may be used to assign fossil leaf mines to Nepticulidae, and suggest useful methods for classifying...

Distribution and evolutionary history of the Early Miocene erinaceid Galerix symeonidisi Doukas, 1986 Naturalis
Hoek Ostende, L.W. van den; Doukas, C.S..
The distribution of the Early Miocene galericine Galerix symeonidisi, with records from Greece, Germany, Spain and Austria is discussed. The identification of G. cf. symeonidisi from the Anatolian Çankiri basin is changed into G. cf. uenayae on the basis of additional material. Galerix symeonidisi enters Europe at the MN 3/ MN 4 transition. Differences in the pattern of replacement of the preceding Galerix species in Germany and Spain suggest that ecological factors played a role in that replacement. Galerix symeonidisi is succeeded by G. exilis in Western and Central Europe. A G. symeonidisi - G. exilis lineage, as has been proposed in literature, is rejected. The record from the Daroca-Calamocha area (Spain) is instead interpreted as a case of gradual...

Three new sympatric species of Remipedia (Crustacea) from Great Exuma Island, Bahamas Islands Naturalis
Koenemann, Stefan; Iliffe, Thomas M.; Ham, Joris van der.
Three new sympatric species of remipede crustaceans, Speleonectes tanumekes, Speleonectes parabenjamini and Speleonectes minnsi, are described from an anchihaline cave on Great Exuma Island in the central Bahamas. Speleonectes tanumekes is a comparatively long and slender species distinguished by the largest number of trunk segments found in remipedes to date. Speleonectes parabenjamini is morphologically closely related to Speleonectes benjamini, but differs from the latter species by several distinct autapomorphies. Speleonectes minnsi is characterized by comparatively robust maxillules. The occurrence of three sympatric species is a remarkable record for the Remipedia adding to a total of 10 sympatric taxa. We discuss the high diversity of remipedes in...
