Two new species of the feather mite genus Proctophyllodes (Analgoidea: Proctophyllodidae) are described from two passerine birds (Passeriformes) in China: Proctophyllodes scleroticus sp. nov. from the Brandt's Mountain Finch Leucosticte brandti pallidior (Fringillidae) and P. micrurus sp. nov. from the White-rumped Snow Finch Onychostruthus taczanowskii (Passeridae). Proctophyllodes scleroticus sp. nov. belongs to the tricetratus species-group, and differs from the most similar species P. petroniae Atyeo & Braasch, 1966 by the following characters: in male, the genital sheath is heavily sclerotized, peach shaped, and extending to the level of setae g, anal suckers are surrounded with a pair of membranes, and terminal lamella is relatively greater, and in female, lobar shield is divided into two independent shields by the anal opening and anal opening extends beyond the level of setae ps1, terminal appendage is long. Proctophyllodes micrurus sp. nov. belongs to the musicus species-group, and differs from the most similar species P. saltatoris Atyeo & Braasch, 1966 by the following characters: in male, genital arch and the anterior part of opisthogastric shield are about the same width, anal suckers are surrounded with a pair of membranes, genital organ extends to the anterior 1/3 of the level of setae g and setae ps3, terminal lamella are located closely to each other and slightly greater, and in female, lobar shields are medially divided into two halves, terminal appendages are small, about 1/10 of setae h3, edge of the cleft is almost horizontal.

Two new species of the feather mite genus Proctophyllodes (Proctophyllodidae: Proctophyllodinae) are described from passerines in the Primorye Territory, Russia: Proctophyllodes bochkovi sp. n. from the blue-and-white flycatcher Cyanoptila cyanomelana (Temminck) (Muscicapidae) and P. cyanopicae sp. n. from the azure-winged magpie Cyanopica cyanus (Pallas) (Corvidae). Proctophyllodes bochkovi belongs to the caulifer species group. It differs from the most similar species, P. cotyledon Trouessart, 1899, in having the genital arch not extending to the level of epimerites IIIa, the terminal lamellae symmetrical with pennate venation and by the absence of the paragenital apodemes in males, and in having a longer lobar region (78–88 μm) in females. Proctophyllodes cyanopicae belongs to the musicus group and is readily distinguished from the most similar species, P. picae (Koch, 1841), in having the hysteronotal shield with well pronounced circular lacunae, and setae g situated closer to the level of setae ps3 than to the genital arch tips in males, and in having the terminal cleft shaped as a longitudinal rectangle 50–55 μm long in females.

Based on the study of type material, other historical specimens, and new collections, the adult of the thelytokous oribatid mite Oribata curva Ewing, 1907 (Galumnidae) is redescribed and the name is recombined to Trichogalumna curva (Ewing, 1907) comb. nov. A confusing history of synonymies and misidentifications is traced in detail, and their effect on published statements about biogeography is assessed. Reliable records of T. curva are only those from North America. The tropical mite Pergalumna ventralis (Willmann, 1932) is not a subspecies of T. curva. The widely-reported Trichogalumna nipponica (Aoki, 1966) and other similar species form a complex with T. curva that needs further morphological and molecular assessment.

A new species of Chirocephalus collected in temporary freshwater ponds in Northeastern Algeria is described. Chirocephalus sanhadjaensis sp. nov. seems to be restricted to Ain-Magroun and Belkroun pools (Skikda Province). The most similar species is C. marchesonii Ruffo & Vesentini, 1957, which is endemic to Italy. The new taxon, belonging to the “diaphanus” species group of the genus Chirocephalus, is identifiable from all congeners primarily by the shape of the antennal appendages and that of the apex of the distal antennomere of the antennae. The resting eggs of C. sanhadjaensis sp. nov. are similar to those of C. diaphanus or C. salinus but are larger (448.24 ± 30.93 µm). The restricted distribution of this species confirms the high biological diversity of the area of the Guerbes-Sanhadja eco-complex.

Two new species of the genus Analges (Astigmata: Analgoidea) are described from two species of accentors (Passeriformes: Prunellidae): Analges himalayanus sp. nov. from the Altai Accentor P. himalayana (Blyth), and A. slovakiensis sp. nov. from the Alpine Accentor Prunella collaris (Scopoli). Both species are closely related to A. bidentatus Giebel, 1871 described from the Dunnock Prunella modularis (Linnaeus). We extended the standard morphological descriptions of feather mites by species delimitation analyses carried out on DNA barcode sequences.

A. midas oberthuri Schaefer, 1938 is elevated to the rank of species, and a lectotype is designated. A. (A.) spathuligera Obenberger, 1924 and A. (A.) midas muelleri Obenberger, 1925 are reconfirmed synonyms of A. midas Kiesenwetter, 1857.All species of the new species-group are illustrated, including the hitherto unknown male of A. (A.) patsyae Baiocchi, 2008, all type specimens and original data labels. In addition to diagnostic characters, informations on the distribution, biology and taxonomic position of each species are also presented, together with a short definition of the new species-group, and a key to its species.

Population Genetic Analyses

The Drosophila nasuta subgroup of the immigrans species group is widely distributed throughout the South-East Asian region, consisting of morphologically similar species with varying degrees of reproductive isolation. Here, I report nucleotide variability data for five X-linked and two mtDNA loci in eight taxa from the nasuta subgroup, with deeper sampling from D. albomicans and its sister species D. nasuta. Phylogenetic relationships among these species vary among different genomic regions, and levels of genetic differentiation suggest that this species group diversified only about one million years ago. D. albomicans and D. nasuta share nucleotide polymorphisms and are distinguished by relatively few fixed differences. Patterns of genetic differentiation between this species pair are compatible with a simple isolation model with no gene flow. Nucleotide variability levels of species in the nasuta group are comparable to those in members of the melanogaster and pseudoobscura species groups, indicating effective population sizes on the order of several million. Population genetic analyses reveal that summaries of the frequency distribution of neutral polymorphisms in both D. albomicans and D. nasuta generally fit the assumptions of the standard neutral model. D. albomicans is of particular interest for evolutionary studies because of its recently formed neo-sex chromosomes, and our phylogenetic and population genetic analyses suggest that it might be an ideal model to study the very early stages of Y chromosome evolution.

Hypsibius Dujardini

A new species of tardigrade from the genus Hypsibius Ehrenberg, 1848 is described from the bottom sediments of a small lake in the central part of Scandinavian Peninsula (Sweden), using an integrative approach, i.e. morphological techniques (light and scanning electron microscopy) combined with a molecular analysis (18S rRNA, 28S rRNA, ITS-2 and COI markers). Hypsibius repentinus sp. nov. belongs to the Hypsibius dujardini species–group and differs from the most similar species of this group in having a second macroplacoid with a definite constriction and in some other morphometric characters. Morphological diagnosis for the Hypsibius dujardini species–group is proposed, and its composition is discussed.
