Enamel Prism Patterns of European Hominoids — and Their Phylogenetical Aspects
1981
Everybody concerned with questions of taxonomy and phylogeny knows that a large part of information used to classify fossil vertebrates is derived from teeth. This comes from the reasoning that teeth are the best mineralized portions of the skeleton and thus usually also the best preserved remains. The best preserved portion of teeth is again the most highly mineralized — the enamel. That the enamel shows a so-called prism pattern, which differs markedly within mammals and also within the primates, is well known since Carter (1922) and Regan (1930) published articles concerning the variability of enamel prism patterns. These were for the first time described by Tomes in 1848. An intensive i…
Fissiphalliidae, a new family of South American laniatorean harvestmen (Arachnida: Opiliones)
2009
Fissiphalliidae, a new family of the Opiliones suborder Laniatores, is described in the superfamily Gonyleptoidea, based on a new genus (Fissiphallius n. gen.) und 3 new species (F. sturmi n. sp., F. spinulatus n. sp., F. sympatricus n. sp.) from Colombia. Most emphasized are the male genitalic characters, unique in Opiliones: A honzontally split truncus which results in a long movable (glans) and an immovable finger (distal part of the truncus). Both hide the extremely long stylus with the seminal opening at its end. In an expanded state, the movable finger is bent dorsally by an erectile vesicle. It is shown that male genitalic characters in Opiliones display clear functional and construc…
Three NewAdelphenaldisSpecies (Hymenoptera: Braconidae: Alysiinae) from Africa, with First Descriptions of the Female ofA. subsurrectionis(Fischer) a…
2014
Three new species of the genus Adelphenaldis from Africa (including Madagascar) are described: Adelphenaldis capensis sp. n., A. mesoafricanus sp. n., and A. noyesi sp. n. The female of A. subsurrectionis (Fischer, 2003) and the male of A. claricornis (Fischer, 1993) are recorded for the first time and described.

Description et differenciation de l’adulte de Hymenolepis cerberensis n. sp. (Cestoda : Hymenolepididae), parasite intestinal de la Musaraigne etrusque, Suncus etruscus (Savi, 1822) (Insectivora : Soricidae : Crocidurinae) capturee sur les communes de Banyuls-sur-Mer et Cerbere (Pyrenees-Orientales, France). La nouvelle espece est caracterisee par la taille des individus gravides et la presence de 18-21 crochets rostraux de 18,5-20 µm de longueur et de filaments autour de l’embryophore. La composition generale de la faune de Cyclophyllidea parasites de S. etruscus est analysee. Il s’agit de trois Hymenolepis peu specialises a scolex du meme type et d’un Pseudhymenolepis , avec absence d’esp…
<i>Limonium vigoi (Plumbaginaceae)</i>, a new tetraploid species from the Northeast of the Iberian Península
1998
SAEZ, L., A. CURCO & J.A. ROSSELLO (1998). Limonium vigoi (Plumbaginaceae), a new tetraploid species from the Northeast of the Iberian Peninsula. Anales Jard. Bot. Madrid 56(2): 269-278. A new tetraploid agamic species, Limonium vigoi, is described from coastal populations of the Northeast of the Spain (Ebro delta). The new species is related, on morphological grounds, to L. girardianum (Guss.) Fourr. and L. grosii L. Llorens, from which it could be easily discriminated by its retuse leaves, the basal ones usually withered at anthesis, the very short (or even absent) leaf apiculum, the denser and longer (up to 0.7 mm) hairs of the calyx tube and the deeper colour of the corolla. In addition…
Lectotypification of the Linnaean name Dianthus virgineus (Caryophyllaceae) and its taxonomic consequences
2021
A lectotype is designated for the name Dianthus virgineus. The relationships between D. virgineus, D. caryophyllus var. caryophyllus, and D. caryophyllus var. inodorus are analyzed. Dianthus virgineus is the oldest available name that applies to a species complex that is often referred to as D. sylvestris or a broad circumscription of the cultivated ornamental D. caryophyllus. The taxonomic consequences are discussed, and the need for further studies is highlighted.
Saprolegnia bulbosa sp. nov. isolated from an Argentine stream: taxonomy and comparison with related species
2007
Saprolegnia bulbosa sp. nov. was isolated from floating and decaying twigs and leaves in El Gato stream, Partido de La Plata, Buenos Aires Province, Argentina. The distinctive characteristics of S. bulbosa are the product of smooth oogonia and predominantly contorted monoclinous, androgynous and diclinous antheridia. The oogonial stalks are usually bent, curved or once coiled; oospores are subcentric, (1) 2–15 (45) per oogonium and are variable in size. Taxonomical description of this new species, its comparison with related oomycetes of the genus and the nucleotide sequences of the internal transcribed region (spacers ITS1, ITS2 and the gene 5.8S) of its rRNA gene are given here.
