Based on field work mostly done in the late 20th century, a survey is given on the diversity and distribution of spring- and stream-dwelling water mites of the family Hygrobatidae in Italy. Five species, all representatives of the subgenus Atractides Koch, 1837 s. str., are described as new to science: Atractides asinus sp. nov., A. castor sp. nov., A. cydonius sp. nov., A. dinisi sp. nov., and A. pollux sp. nov.. A further 13 species are recorded for the first time from Italy: Atractides anellatus Lundblad, 1956, A. asticae Petrova, 1968, A. denticulatus Walter, 1947, A. fissus (Walter, 1927), A. fluviatilis (Szalay, 1929), A. glandulosus (Walter, 1918), A. graecus K. Viets, 1950, A. lunipes Lundblad, 1956, A. remotus Szalay, 1953, A. subterraneus (K. Viets, 1932), Hygrobates arenarius Smit & Pešić, 2017, H. setosus Besseling, 1942, and H. cf. turcicus Pešić, Esen & Dabert, 2017. In summary, a total number of 66 hygrobatid species is now known from the area treated. Previous records of Atractides allgaier Gerecke, 2003 from Corsica and Sardinia, and of A. lunipes Lundblad, 1956 from Corsica, refer to A. castor sp. nov., resp. A. corsicus E. Angelier, 1954. Redescriptions are given for seven remarkable and/or incompletely documented species: Atractides asticae, A. fluviatilis, A. graecus, A. inflatipalpis K. Viets, 1950, A. lunipes, A. protendens K.O. Viets, 1955, and A. remotus. Problems concerning diagnostic features are discussed for several species. Atractides fluviatilis, A. valencianus K. Viets, 1930 and A. inflatipalpis, along with two species not recorded from Italy, namely A. algeriensis (Lundblad, 1942) and A. stancovici Pešić & Gerecke, 2010, are summed up in a “fluviatilis species group”. Within this clade, several species tend to grade into each other morphologically, and females cannot be classified with certainty.

AbstractMorphological, life history, and distributional data are presented for North American species of the subgenus Stygomomonia (sensu stricto) Szalay, 1943. Adults of the seven previously recognized species are redescribed, and deutonymphs of five of these species are described for the first time. Two species, S. (s.s.) neomexicana Cook and S. (s.s.) occidentalis Cook are substantially revised on the basis of an examination of the types and extensive series of newly collected specimens. Three new species are described, S. (s.s.) californiensis on the basis of deutonymphs and adults, and S. (s.s.) imamurai and S. (s.s.) cooki on the basis of adults. A new diagnosis of the subgenus is proposed and discussed, the relationships of the various species are discussed, and a key to deutonymphs and adults of North American species is presented. New distributional data are presented for all species, and dispersal patterns from Pleistocene refugia are discussed.

Introduction. The article reviews background studies on the Mansi language and its dialects performed by European and Russian (Soviet) linguists. Goals. The paper seeks to provide a comprehensive historical description of Mansi language research. Methods. The descriptive and comparative-historical methods have been employed thereto. Results. The work arranges the studies chronologically — from earliest research activities to contemporary ones — highlighting most essential achievements. Mansi is one of the least studied languages with earliest written accounts dating to the 16th-17th centuries. The earliest Mansi dictionaries were compiled by explorers and missionaries (I. Kuroedov, S. Cherkalov, P. S. Pallas, etc.) in the 18th century. In the 19th century, the Mansi language officially became a subject of scientific research, and expeditions by Finnish and Hungarian linguists (Antal Reguly, August Engelbrekt Ahlqvist, Bernát Munkácsi, Artturi Kannisto) proved the first field studies. In the 20th century, quite a number of European scientists have contributed to Mansi language research, namely: W. Steinitz, L. Honti, K. F. Кarjalainen, M. Bakró-Nagy, K. Rédei, M. Szilasi, and others. In Russia, the first Mansi studies were initiated by Soviet scholars in the 1930s (V. Chernetsov, A. Balandin). Studies in spoken Mansi evolved into a national Cyrillic alphabet, and for the first time ever there were published comprehensive works dealing with Mansi studies, textbooks on Mansi phonetics, morphology, and grammar. Experimental phonetic explorations emerged in the mid-to-late 20th century resulting in new Mansi dictionaries (A. Sainakhova, T. FrankKamenetskaya, E. Rombandeeva, and others). Mansi studies in the 21st century in Russia and Europe have reached a brand new level: there appeared online research laboratories and linguistic platforms which make it possible to further investigate the Mansi language and verify up-to-date materials.

There are few records of beetles of the family Elateridae from Tanegashima Island, in the Ôsumi Islands, in the Ryukyu Islands, Japan, and the elaterid fauna of this island has not been reviewed. We examined newly collected specimens and reviewed the previous records from the island. In field work and from a colleague’s collection, we found 27 species, of which 13 were recorded for the first time on the island. As result 43 species are confirmed from this island and a checklist of all elaterid species from Tanegashima Island is provided.

Ecological Differences

New records of marine mites of the family Pontarachnidae Koenike, 1910 (Acari: Hydrachnidia) from the southern Black Sea (Sinop bay, Turkey) are presented. Two species, i.e., Pontarachna valkanovi Petrova, 1978 and Pontarachna adriatica Morselli, 1980 are recorded for the first time from Turkey. These are the first records of these species after its orginal description. Our study shows ecological differences between these species: Pontarachna valkanovi were collected from 3 m depth, while P. adraitica seems to be characteristic for deeper waters (10 m depth).

A general introduction to the water mites of Madagascar is given, together with a survey of the diversity of the early derivative superfamilies Eylaoidea, Hydrachnoidea, and Hydryphantoidea. The family Teratothyadidae (genera Teratothyas and Teratothyasides) and the hydryphantid subfamilies Euthyadinae (genera Javathyas and Trichothyas) and Wandesiinae (genus Wandesia) are recorded for the first time from Madagascar, the latter being new for the Ethiopian bioregion. One subgenus in the family Teratothyadidae, Ascoteratothyas subgen. nov. (genus Teratothyas) and eighteen species are described as new to science: Hydrodroma amoenoderma, H. lasioderma, H. megalonyx, H. mesembrina, H. poseidon, Javathyas nasipalpis, Wandesia pelipoda, W. anjozorobensis, Teratothyas (s. str.) digitata, T. (s. str.) aucta, T. (s. str.) proceripapillata, T. (s. str.) planipapillata, T. (Ascoteratothyas) levigata, T. (A.) porrigens, T. (A.) reducta, Teratothyasides heptaplax, T. ravenala and T. vanilla. Previous Madagascan records of Hydrodroma despiciens (Müller, 1776) and H. capensis (K. Viets, 1914) are attributed to H. poseidon. The subgenus Pseudowandesia is synonymized with the nominate subgenus. New locality records for other species include the first recording on the island of Hydrodroma perreptans (K. Viets, 1913) and H. zhokhovi Tuzovskij, 2014. Limnochares connexa Tuzovskij & Gerecke 2009 is redescribed. A dichotomous key leads to species level for the groups treated here, to family level for representatives of the remaining four superfamilies present on Madagascar.

A New Species

The holometabolous order Raphidioptera is recorded from Xizang Autonomous Region for the first time. A new species of the family Inocelliidae, Inocellia tibetana sp. nov., from southeastern Xizang is described and its two sexes illustrated. Based on the male gonocoxite 9 that is longer than width of its base, the new species belongs to the I. fulvostigmata species-group, and it appears to be closely related to I. fulvostigmata U. Aspöck, Rausch & H. Aspöck, 1968. Both species are distributed near the southern edge of the Himalayas. The male of the new species is characterized in the genitalia by the presence of a membranous, short and digitiform gonostylus 9, the gonarcus (fused gonocoxites 11) subtriangular in caudal view dorsally with a pair of short tubercular processes, and the reduction of bristle tuft on the endophallus.

Phyllophorella was recently described from two localities on the central coast of Peru (12°S), based on the endemic species Phyllophora (Ph.) peruviana. The genus currently accommodates three species, Phyllophorella (P.) peruviana, P. humboldtiana and P. limaensis. Recent field surveys for Phyllophorella on the central coast of Peru led to the discovery of collections outside the originally reported ranges. Morphological, anatomical, and genetic characterization of the specimens confirms range extensions for P. peruviana to 9° S and 15° S, and P. humboldtiana to 12° S and 15° S. A combined phylogenetic analysis of rbcL and COI-5P gene sequences supports the taxonomic status of these two species and reasserts the genus as monophyletic. Anatomically, the two species differ in nemathecial structure. Phyllophorella peruviana displays dome-shaped and well-defined circular nemathecia, whereas in P. humboldtiana they are irregular and diffuse in form. Mature cystocarps were observed for the first time in Phyllophorella, in P. humboldtiana from Lima and Ica, Peru. Phyllophorella, as well as the other genera classified to the family Phyllophoraceae, have a procarpic sexual system, with a carpogonial branch of three cells; the cystocarp develops a thickened cortex, is immersed in the medulla, and lacks a pericarp and an ostiole. This study demonstrates that field work, together with morphological, developmental, and genetic analyses, are useful methods for improving our understanding of seaweed distributions and systematics.

This paper deals with a collection of epigean and hypogean water mites from the Hormozgan and Sistan va Baluchestan prov-inces in southern Iran. One new genus, Haloaxonopsis, is described, characterized by the presence of so-called wheel-likeacetabula, a unique character so far known only in marine mites of the family Pontarachnidae. One new subgenus, Halolimne-sia, and fourteen new species are described: Hydrachna sistanica, Nilotonia hormozgana, Torrenticola asadiae, T. hormozgan-ensis, Monatractides martini, Neoatractides calidus, Limnesia diversipes, Atractides hormozganus, Javalbia persica,Axonopsis gloeeri, A. interstitialis, A. hyporheica, Haloaxonopsis salina and Albia hyporheica. The first descriptions of thefemale are given for Neumania cf. maharashtris Cook, 1967 and Arrenurus bharatensis Cook, 1967. The following species arereported for the first time in Iran: Hydrachna cf. vaillanti K. Viets 1951, H. globosa lacerata Lundblad, 1969, Diplodontus sil-vestrii (Daday, 1898), Hygrobates hamatus K. Viets, 1935, Atractides biscutatus Cook, 1967 and Arrenurus bharatensis Cook,1967. The zoogeographical and ecological characteristics of the water mite fauna of southern Iran are discussed. The fauna ofSE Iran is of Oriental character, and no typical Palaearctic species were found. Our study shows that this fauna is not transitional, suggesting a rather ‘sharp’ boundary between the Palaearctic and Oriental regions in southern Iran.

Eleven Species

Species of the family Anthomyzidae (Diptera: Acalyptrata) occurring in Taiwan are reviewed. Eleven species have been recognized, 8 of them new to science. However, because of limited and poorly preserved material, only three species of the genus Anthomyza Fallén, 1810, viz. A. robusta sp. nov. (Chiayi and Nantou Counties, both sexes), A. caesarea sp. nov. (Taichung City area, both sexes) and A. elongata sp. nov. (Chiayi County, female only), are described. The remaining 5 undescribed species, viz. Amygdalops sp. nov. near cuspidatus (Taichung City area), Amygdalops sp. nov. near curtistylus (Nantou and Kinmen Counties), Anthomyza sp. nov. near elongata (Yilan County), Anthomyza sp. nov. (1) near flavosterna (Chiayi County) and Anthomyza sp. nov. (2) near flavosterna (Nantou County), are diagnosed but remain unnamed. A new species group of Anthomyza, viz. the A. flavosterna group, is established and diagnosed, to include the East Palearctic A. flavosterna Sueyoshi & Roháček, 2003, A. caesarea sp. nov., A. elongata sp. nov. and 3 additional unnamed species from Taiwan, while the remaining A. robusta sp nov. belongs to the A. bellatrix group. All six Taiwanese Anthomyza species seem to be associated with montane habitats and could be endemic. It is estimated that up to 20 species of Anthomyzidae could occur in Taiwan. The longitudinal dark pattern of the wing, found in A. caesarea sp. nov., is recorded for the first time in the genus Anthomyza which is the fourth lineage of Anthomyzidae in which this type of pattern has independently evolved. Preliminary keys to Taiwanese species of the genera Amygdalops Lamb, 1914 and Anthomyza are presented.

The paper describes the external structures of the late larval stages of two Palearctic myrmecophilous staphylinids:AmidobiatalpaandOxypodahaemorrhoaassociated with theFormicarufaspecies group. This is the first-ever description of the larva ofAmidobia, and the only complete, detailed account of the morphology of this developmental stage in the genusOxypodacurrently available. For the first time in these two genera, 13 and 10 larval diagnostic features, respectively, are proposed. Morphological differences have been established between known and the newly described larvae of five species (genera) of myrmecophilous and one non-myrmecophilous Aleocharinae, belonging to three tribes.AmidobiatalpaandO.haemorrhoaare probably typical, tiny predators, like most other Aleocharinae, including non-myrmecophilous ones. Being very small and highly mobile, they are ignored by worker ants. Not surprisingly, no particular larval morphological modifications were found to enable them to survive among ants. Such features have, however, evolved in the larvae of larger aleocharines, that is, those that are perceived by ants and are wholly integrated with their hosts in the ant nest (e.g.Lomechusa). This comparative analysis of the functional morphology of the larvae of known myrmecophilous Aleocharinae is a springboard to further such studies of these interesting insects.
