AbstractEnneastigma is a small genus of myopinine anthomyiids which comprises five species in the Mediterranean subregion (E. compressum Stein, E. rarum sp. n., E. rufitibia sp. n., E. triplex Loew, E. triseriatum Stein) and two species in SE Palearctic part of China (E. pilosiventrosum Fan & Chen, E. shanghaiensis Fan & Chen). All species appear to be univoltine and only active during the cooler parts of the season. The larvae may all be coprophagous. The Mediterranean species are revised with keys to males and females and illustrated descriptions of males, females and eggs. One lectotype is designated. A cladistic analysis was conducted which also included the Chinese species. This resulted in a single, most parsimonious phylogeny. The resulting area cladogram was used to assess the alternative methods for estimating ancestral areas as proposed recently by K. Bremer and F. Ronquist. It is concluded that the best results are obtained by using a refined Ronquist analysis.

The genus Epileucon Jones, 1956 is redefined on the basis of carapace, pereon and appendage characters. The following species are transferred to Epileucon from the genus Leucon Kröyer, 1846: E. spiniventris (Hansen, 1920), E. longirostris (G. O. Sars, 1871), E. tenuirostris (G. O. Sars, 1887), E. latispina (Jones, 1963) and E. bengalensis (Lomakina, 1967). A lectotype is selected for E. spiniventris . Known Atlantic and Mediterranean species are redescribed, and five new species, E. ensis, E. pusillus, E. craterus, E. socius and E. acclivis , are described. Keys to males and females of the Atlantic and Mediterranean species are provided. The geographical distribution of the group is discussed. The genus is known in deep water (> 200 m) in the Atlantic, Pacific and Indian oceans and in the Mediterranean Sea, and also on the continental shelf (at around 100 m depth) off New Zealand.

The diagnostic characters of the genus Lotus L. are a claw with a thickened infolded margin, diadelphous stamens, and a style hardened from the base. This genus contains about 100 species that are distributed throughout the world. To investigate the phylogeny of the Old World species of Lotus, subgenus Edentolotus, sections Krokeria, Xantholotus, and Erythrolotus, a cladistic analysis was performed using 31 morphological characters. To test the phylogenetic relationships among species of Lotus-Edentolotus and Dorycnium, Pedrosia, and Tetragonolobus, these taxa were included as part of the ingroup. The polarity of the characters was based on the outgroup comparison method, using Anthyllis as one outgroup and Tripodion as another. The analysis with Anthyllis as outgroup yielded eight equally parsimonious trees (with all characters equally weighted), each with 62 steps, a consistency index of 0.53, and a retention index of 0.75. All trees (including the strict consensus tree from the eight initial trees) showed that genus Lotus, subgenus Edentolotus, and sections Xantholotus and Erythrolotus are polyphyletic, with only section Krokeria appearing as monophyletic. On the other hand, the groups of species Lotus angustissimus, Lotus corniculatus, Lotus creticus, and Lotus peregrinus are monophyletic. Identical results were derived from the data matrix using Tripodion as the outgroup. Results are compared with previous cytogenetic and biochemical evidence.Key words: cladistic analysis, Fabaceae, Loteae, Lotus, Old World species, phylogeny.

A new species of Chone (Sabellidae) from the coast of Ustica Island (Mediterranean Sea, north of Sicily) is described. The species, named Chone usticensis sp. nov., is similar to another Mediterranean species, C. filicaudata, in having a long pygidial filiform appendage, but is distinct from this species especially in the peristomium, collar, and in thoracic paleate chaetae shape. A discussion on the presence of the radiolar appendages within the genus Chone is also given.

The European and Mediterranean species of the Acalyptris platani and A. staticis groups are revised, with respectively four and six species. Three new species are described: A. pistaciae Van Nieukerken sp. n. (from Greece, Cyprus and Turkey, on Pistacia) in the platani group, A. limoniastri Van Nieukerken sp. n. (from Algeria and Tunisia, associated with Limoniastrum) and A. lesbia Van Nieukerken & Hull sp. n. (from Greece: Lesvos, on Limonium gmelini) in the staticis group. Lectotypes are selected for A. minimella (Rebel, 1924) and A. staticis (Walsingham, 1908). The European species of the A. platani group are leafminers on Anacardiaceae, Platanaceae and Loranthaceae, the species of the A. staticis group feed on Plumbaginaceae, except A. pyrenaica A. & Z. Laštůvka, for which the host is unknown, but likely to belong to another family. Immatures are described for five species, final instar larvae and pupal exuviae for all species in the A. platani group and for A. lesbia. Larvae and pupae of the latter species differ markedly from the A. platani group. Recorded parasitoids are listed. CO1 barcodes are provided for seven species. The groups are phylogenetically not very close; the monophyly of Acalyptris and the phylogeny on the basis of CO1 (mt-DNA) sequences are discussed.

A systematic account is presented of the species of the Tipula (Acutipula) maxima group. To the eleven species and subspecies already known, six are added as new: maxima balcanica, transcaucasica latifurca, libanica, cretensis, isparta, and cypriensis. Of all taxa the genital structures of the males and females are described and figured. These structures allow a grouping of the species into five subgroups. The distribution of the species and subspecies is mapped; they are all limited to smaller areas in the Mediterranean region, but for maxima itself which occupies almost entire Europe.
