Eleven Species

The species of Orientopsaltria with unicolorous opercula and three related species of Platylomia are transferred to the genus Dundubia and allocated in the ‘Dundubia jacoona assemblage’ pending further investigation. The assemblage comprises eleven species in total; all are found in the Indo-Malaysian Archipelago, Indo-China, and the adjoining parts of China and India. The four species which were until now placed in Orientopsaltria are D. feae (Distant, 1892), D. jacoona (Distant, 1888), D. nigripes (Moulton, 1923), and D. oopaga (Distant, 1881). The three species transferred from Platylomia are D. hainanensis (Distant, 1901), D. nagarasingna Distant, 1881, and D. spiculata Noualhier, 1896. These seven species are all redescribed. Four species are described as new: D. ayutthaya, D. laterocurvata, D. myitkyinensis and D. sinbyudaw. Seven species are synonymized: O. andersoni (Distant, 1883) with D. oopaga, D. bifasciata Liu, 1940 with D. hainanensis, O. hastata (Moulton, 1923) and D. siamensis Haupt, 1918 with D. spiculata, O. fratercula (Distant, 1912) and D. helena Distant, 1912 with D. nagarasingna, and D. longina Distant, 1917 with D. feae. Lectotypes are designated for the following species: Cosmopsaltria andersoni, C.feae, C. fratercula, C. hastata, C. nagarasingna, C. nigripes, C. oopaga, D. helena, D. longina, and D. spiculata. A key to the males is presented and the distributions of the species are discussed. The relationships of the D. jacoona assemblage with Dundubia, Platylomia, and the remaining species of Orientopsaltria are discussed. The species of the D. jacoona assemblage most likely do not form a monophyletic group on their own but rather with Dundubia s. str.

The long-tailed parakeets of the genus Psittacula Cuvier, 1800 have thus far been regarded as a homogeneous and monophyletic group of parrots. We used nucleotide sequences of two genetic markers (mitochondrial CYTB, nuclear RAG-1) to reconstruct the phylogenetic relationships of Psittacula and closely related species. We found that the Asian genus Psittacula is apparently paraphyletic because two genera of short-tailed parrots, Psittinus Blyth, 1842 and Tanygnathus Wagler, 1832, cluster within Psittacula, as does †Mascarinus Lesson, 1830. To create monophyletic genera, we propose recognition of the following genera: Himalayapsitta Braun, 2016 for P. himalayana, P. finschii, P. roseata, and P. cyanocephala; Nicopsitta Braun, 2016 for P. columboides and P. calthrapae; Belocercus S. Müller, 1847 for P. longicauda; Psittacula Cuvier, 1800 for P. alexandri and P. derbiana; Palaeornis Vigors, 1825 for †P. wardi and P. eupatria; and Alexandrinus Braun, 2016 for P. krameri, †P. exsul, and P. (eques) echo. Additionally, Psittacula krameri and P. alexandri are paraphyletic species, which should be split to form monophyletic species.

Research Areas

Despite their unmatched popularity in many research areas, microsatellites have not yet become a major tool for the inference of genealogical relationships of closely related species. Recent studies have successfully extended the repertoire of microsatellite analysis beyond population genetics and demonstrate that phylogenetic relationships of closely related species can be inferred accurately with fewer loci than previously assumed.

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

The genus Minuartia is represented in Turkey by 34 taxa. Some interesting specimens were collected from Antalya province, and examined. These specimens resemble Minuartia meyeri, and M. multinervis from which differ by characters (macro-, and micromorphological) of inflorescence, alar pedicels, petals, sepals, capsules and seeds. Moreover, by using the DNA sequences of the ITS genes, phylogenetic relationships between this collected species, and the related species were investigated. As a result of the evaluation of molecular, and morphological data, we proposed to described the population from Antalya as a new species for the science. A description, pictures, distribution, habitat, and IUCN category are given.

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.

Chromosomal Sequence

SummaryThe extent of accumulation of mouse Y chromosomal repetitive sequences generally correlates with the known phylogenetic relationships in the genus Mus. However, we describe here a M. musculus Y chromosomal repetitive sequence, designated as ACClfl, whose accumulation patterns among eight Mus species do not correspond to their phylogenetic relationships. Although male-specific hybridization bands were present in all the species examined, significant accumulation (> 200 copies) in the Y chromosomes was found in M. minutoides (subgenus Nannomys), M. pahari (subgenus Coelomys) and M. saxicola (subgenus Pyromys) as well as in the three closely related species M. hortulanus, M. musculus and M. spretus that belong to the subgenus Mus. Unexpectedly, the Y chromosomes of M. caroli and M. cookii (both subgenus Mus) had considerably reduced amounts of ACClfl-related sequences. Furthermore, in rats (Rattus norvegicus) the major accumulation sites appear to be autosomal. These observations suggest that caution must be taken in the interpretation of data obtained with repetitive sequences that have evolved quickly.

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.
