The genus Trichadenotecnum Enderlein, 1909 is redefined as a monophyletic group. The following 22 Japanese species are treated and classified into five species-groups except one species not placed in a group: sexpunctatum-group – T. album, sp. nov., T. incognitum Roesler, 1939; medium-group – T. takahashii, sp. nov., T. mixtum, sp. nov., T. magnomixtum, sp. nov., T. amamiense, sp. nov., T. okinawense, sp. nov., T. yonaguniense, sp. nov., T. kumejimense, sp. nov., T. latebrachium, sp. nov., T. pseudomedium, sp. nov., T. yaeyamense, sp. nov.; alexanderae-group – T. alexanderae Sommerman, 1948, T. castum Betz, 1983, T. sexpunctellum (Enderlein, 1907); majus-group – T. yamatomajus, sp. nov., T. nothoapertum, sp. nov.; spiniserrulum-group – T. falx, sp. nov., T. furcalingum, sp. nov., T. pardidum Thornton, 1961, T. circularoides Badonnel, 1955; incertae sedis – T. fuscipennis, sp. nov. The monophyly and phylogenetic relationships of these species-groups are discussed. A key to Japanese species of Trichadenotecnum is given.

AbstractPhylogenetic relationships among the genus Dichaetophora, the genus Nesiodrosophila and the Lordiphosa tenuicauda species-group and some possibly related genera of Drosophilinae were analyzed in this study using 30 morphological characters derived from 34 species. It is concluded that the three taxa constitute a monophyletic group, within which three monophyletic groups are recognized: Dichaetophora + Nesiodrosophila comprise a monophyletic group, while the L. tenuicauda group is divided into two monophyletic groups. This clade is revised as the genus Dichaetophora, with its three constituent monophyletic groups treated as new specis-groups: the agbo, the tenuicauda and the acutissima groups. Nesiodrosophila becomes a junior synonym. A key to the species-groups is provided.

Species Descriptions

The phylogenetic relationships of 23 oxyurid species from five genera (21 parasite species of the Palaearctic Testudinidae, 1 parasite species of Uromastix acanthinurus Bell, 1825 from Algeria, and 1 parasite species of Cteno sa ura pectinata (Wiegmann, 1834) from Mexico) were investigated using 30 morphological characters obtained from species descriptions. The nonweighted analysis produced one shortest tree. All species of the ingroup form a monophyletic group and the oxyurid species of Testudinidae form a monophyletic group. The type species of the genus Alaeuris Thapar, 1925 is the basal member of the species parasitizing Testudinidae. The analysis confirms the monophyly of the genus Thaparia Ortlepp, 1933, whereas the genera Mehdiella Seurat, 1918 and Tachygonetria Wedl, 1862 are considered paraphyletic groups. The large diversification in the genus Tachygonetria is linked to their position in the host caecum. The ancestral state is in the paramucous and the derived state is in the centre of the caecum. This suggests that recent speciation in the group occurs in the centre of the caecum.

Abstract Background The behavioural repertoire of every species evolved over time and its evolution can be traced through the phylogenetic relationships in distinct groups. Cranes (family Gruidae) represent a small, old, monophyletic group with well-corroborated phylogenetic relationships on the species level, and at the same time they exhibit a complex and well-described behavioural repertoire. Methods We therefore investigated the evolution of behavioural traits of cranes in a phylogenetic context using several phylogenetic approaches and two types of trait scoring. The cranes exhibit more than a hundred behavioural displays, almost one third of which may be phylogenetically informative. Results More than half of the analysed traits carry a significant phylogenetic signal. The ancestor of cranes already exhibited a quite complex behavioural repertoire, which remained unchanged in Balearicinae but altered greatly in Gruinae, specifically by the shedding of traits rather than their creation. Trait scoring has an influence on results within the Gruinae, primarily in genera Bugeranus and Anthropoides. Conclusions Albeit the behavioural traits alone cannot be used for resolving species-level relationships within the Gruidae, when optimized on molecular tree, they can help us to detect interesting evolutionary transformations of behaviour repertoire within Gruiformes. The Limpkin (Aramus guarauna) seems to be the most enigmatic species and should be studied in detail for its behavioural repertoire, which may include some precursors of crane behavioural traits.

A new species of Canthon is described, illustrated and the morphological similarities with related species are discussed. The species Canthon cleidecostae was named after Dr. Cleide Costa a great beetles specialist. The subgeneric category of species is considered incertae sedis until the taxonomic revision of the genus Canthon is fully addressed. Also, we provide a key for genera, subgenera and isolated species-groups that can be confused with the genus Canthon.

A New Species

The genus Elaphropeza Macquart from the Oriental region is revised. In addition to the 79 known species (including seven new combinations of species previously placed within Drapetis Meigen) 51 new species are described and illustrated. The study is mainly based on freshly collected material in Singapore (544 samples, year cycle in eight stations and numerous hand captures). Smaller samples were available from Malaysia, Thailand and Cambodia. Of the 51 new species only 43 have been given a name: E. acantha sp. nov., E. asexa sp. nov., E. asiophila sp. nov., E. belumut sp. nov., E. benitotani sp. nov., E. bezzii sp. nov., E. bulohensis sp. nov., E. chekjawa sp. nov., E. combinata sp. nov., E. crassicercus sp. nov., E. darrenyeoi sp. nov., E. demeijerei sp. nov., E. equalis sp. nov., E. feminata sp. nov., E. flavicaput sp. nov., E. furca sp. nov., E. limosa sp. nov., E. luanae sp. nov., E. luteoides sp. nov., E. malayensis sp. nov., E. meieri sp. nov., E. melanderi sp. nov., E. modesta sp. nov., E. monacantha sp. nov., E. monospina sp. nov., E. murphyi sp. nov., E. neesoonensis sp. nov., E. ngi sp. nov., E. pauper sp. nov., E. pluriacantha sp. nov., E. riatanae sp. nov., E. sime sp. nov.,E. singaporensis sp. nov., E. singulata sp. nov., E. sivasothii sp. nov., E. spicata sp. nov., E. spiralis sp. nov., E. sylvicola sp. nov., E. temasek sp. nov., E. tiomanensis sp. nov., E. ubinensis sp. nov., E. yangi sp. nov., E. yeoi sp. nov. Eight species known only as females are briefly diagnosed but not named. Species (including type materials in most cases) described by C.R. Osten-Sacken, M. Bezzi, J.C.H. de Meijere, R. Senior-White, A.L. Melander and K.G.V. Smith were examined and re-described. Neotypes have been designated for E. calcarifera Bezzi, E. melanura Bezzi, E. formosae Bezzi and E. scutellaris Bezzi. Elaphropeza exul Osten-Sacken, 1882 is transferred as Crossopalpus exul (Osten-Sacken) comb. nov. Elaphropeza formosae Bezzi sensu Quate, 1960 re-described by L.W. Quate from Micronesia, is considered a new species and a new name is given: E. quatei sp. nov. All species of Elaphropeza are divided into two main species groups: E. biuncinata group and E. ephippiata group. Phylogenetic relationships within Elaphropeza are provisionally outlined. Some interesting morphological features and phenology of the species are discussed. Fourteen species have been found exclusively in mangroves. A key is given to the species of the Oriental Region (Indian subcontinent, Southeast Asia, Philippines and Taiwan, but excluding certain species of the Chinese mainland that proved to be different from the rest of the Oriental Region). A check list of the Oriental species is provided.

Abstract Parasesarma is a species-rich genus whose representatives are common in wetlands and mangroves of the Indo-Pacific. Morphologically, the genus is heterogeneous and has been postulated to constitute a polyphyletic taxon. In the present study, most species of Parasesarma are re-evaluated phylogenetically, using mitochondrial and nuclear molecular markers. The results show that the majority of the examined species cluster consistently with the type species Parasesarma plicatum. However, some species, among them the tree-climbing Parasesarma leptosoma, are clearly separated from this main clade of Parasesarma, forming a second stable monophyletic group, distinct from other known genera. Based on these results, and with additional support by morphological diagnoses highlighting consistent differences between the two species groups, we propose a new genus for the species clustering around P. leptosoma, proposing the new name Leptarma gen. nov.

The Subject

The family Alestidae (also referred to as the African Characidae) comprises the African dwarf forms ("Petersiini") and the genera Alestes, Brycinus, Bryconaethiops, and Hydrocynus. Although several authors have presented characters to support the monophyly of the family, a cladistic analysis of the group has not been published. Furthermore, the interrelationships of the constituent groups are the subject of some controversy. A cladistic analysis of the Alestidae is presented, including characters to support the monophyly of the family. The results of this study indicate that several species should be removed from the genus Brycinus, that Hydrocynus is the sister group of Alestes s.str. (containing only five species), and that the dwarf alestids ("Petersiini") do not form a monophyletic group.
