A new genus and species of mite (Acari: Acaridae) from Mexico

Comerinia chuetolamina gen. & sp. nov. was collected from a cargo of dried Daphnia imported to Britain from Mexico. Females can be distinguished from all others described in the family Acaridae in that setae 14, 15 and d5 are flattened dorsoventrally over most of the basal half. This region appears blade-like, bearing numerous strong pectinations along the ventral side. Males may be recognized by a series of characters, some of which reflect a close relationship with Forcellinia Ouds., 1924 and others with Tyrophagus Ouds., 1924. The position of the new genus in a commonly used key to adults of the family Acaridae is indicated.     

A new quill mite species (Acari: Syringophilidae) parasitising tinamous (Aves: Tinamiformes)

Tinamiphilopsis ariconte n. sp., a syringophilid mite, is described from three tinamou species (Tinamidae), Rhynchotus rufescens (Temminck) and Nothura boraquira (Spix) in Paraguay and N. minor (Spix) in Brazil. These data indirectly support the hypothesis that the cheyletoid-like predatory ancestor of the Syringophilidae switched to parasitism before the divergence of the avian hosts into the two major clades Palaeognathae and Neognathae.     

A new genus of Decticinae (Orthoptera: Tettigoniidae) from the Middle East

A new genus, Raggeana, is erected for Metrioptera bodenheimeri Uvarov, and the hitherto unknown female of this species is described.     

Two new species of larval mites (Acari: Trombidioidea: Microtrombidiidae and Johnstonianidae) parasitising Culicoides impunctatus,the highland midge (Insecta: Ceratopogonidae), in Scotland

The larval stage of the trombidioid mites Parafeiderium stuarti n. sp. (family Microtrombidiidae Thor, 1935) and Centrotrombidium blackwellae n. sp. (family Johnstonianidae Newell, 1957) are described. Both species were found parasitising Culicoides impunctatus Goetghebuer, the highland midge (Diptera: Ceratopogonidae), in Scotland. A revised diagnosis for Parafeiderium Vercammen-Grandjean & Cochrane, 1974 and a key to the world species of larval Centrotrombidium Kramer, 1896 are given.     

A new oribatid mite species of the genus Sphaerozetes (Acari,Ceratozetidae) from Vietnam

A new oribatid mite species, Sphaerozetes bugiamapensis sp. n., is described from the Bu Gia Map National Park (Vietnam). The genus Sphaerozetes is recorded from Vietnam for the first time.     

A new genus and species in the mite family Eupodidae (Acari,Eupodoidea) from Crimea

A new genus Pseudoeupodes Khaustov, gen. n. and new species Pseudoeupodes porosus sp. n. are described from moss in Crimea. The taxonomy of the Eupodidae and some other families and genera of Eupodoidea is reviewed. The genus Turanopenthalodes Barilo, 1988 is transferred from Penthalodidae to Penthaleidae. The family Cocceupodidae Jesionowska, 2010 and the genus Filieupodes Jesionowska, 2010 are considered as junior synonyms of Eupodidae Koch, 1842 and Cocceupodes Thor, 1934, respectively. A key to genera of the family Eupodidae is provided.     

A new species of the mite genus Dolichocybe (Acari, Heterostigmata, Dolichocybidae) from the Crimea

A new species from the Crimea, Dolichocybe subcorticalis, is described and illustrated. It was found under the bark of Salix sp. in galleries of the beetle Trypophloeus rybinskii Reitter. A key to the all known species of the genus Dolichocybe is given.

Abrolophus crimensis sp. n., Valgothrombium melindae sp. n. from Ukraine, Moldoustium baltiensis gen. n., sp. n. from Moldova and Ukraine and Podothrombium dbrenitum sp. n. from Moldova are described. Rudaemannia rudaensis (Haitlinger), Trombidium dacicum (Feider) are new for the fauna of Moldova, Grandjeanella multisetosa Zhang et Goldarazena, Leptus (Leptus) trimaculatus (Hermann), Erythraeus (Zaracarus) preciosus Goldarazena et Zhang, E. (E.) kuyperi (Oudemans), Balaustium nikae Haitlinger, Johnstoniana eximia (Berlese) are new to the fauna of Ukraine, Hauptmannia brevicollis Oudemans, H. wratislaviensis Haitlinger, Abrolophus pseudolongicollis kiejstuti Haitlinger, Charletonia krendowskyi (Feider), Allothrombium fuliginosum (Hermann), A. triticium Zhang, Trombidium holosericeum (L.) and Podothrombium proti Haitlinger are new to the fauna of Moldova and Ukraine. The following new synonyms and new combination are proposed: Canpicatrombium Haitlinger, 2003 syn. n. = Valgothrombium Willmann, 1940, Leptus (Leptus) echinopus Beron, 1975 syn. n. = L. (L.) trimaculatus (Hermann, 1804), Valgothrombium mallorcensis (Haitlinger, 2003) comb. n., Podothrombium proti Haitlinger, 1994 is not synonym of P. filipes (C.-L. Koch, 1837).     

A new oribatid mite species of the genus Protoribates (Acari,Oribatida, Haplozetidae) from Ethiopia

A new oribatid mite species, Protoribates aethiopicus sp. n., from Ethiopia is described. This species is morphologically similar to Protoribates dentatus (Berlese, 1883), but differs from it in the longer lamellae and notogastral setae, shorter adanal setae ad ₁ and smaller notogastral porous areas, as well as in the presence of two claws on all legs.     

A new genus and four new species of quill mites (Acari: Prostigmata: Syringophiudae) from phasianid birds (Galuformes: Phasianidae)

A new genus and four new species of the quill mites are described. Galliphilopsis gen. n. (G. francolinus sp. n., type species) differs from the closely related Dissonus Skoracki, 1999 by loss of leg setae dGII, the slightly divergent tips of epimeres I and the stylophore constricted posteriorly. Three new species of the genus Galliphilopsis gen. n. and one new species of the genus Mironovia Chirov and Kravtsova, 1995 are described from galliform birds (Phasianidae) collected at the Museum of Natural History, Wroclaw University (Poland): G. lophurus sp. n. from Lophura leucomelanos, G. bochkovi sp. n. from Tragopan sp. and Alectoris barbara, G. francolinus sp. n. from Francolinus levalliantoides, and Mironovia rouloul sp. n. from Rollulus rouloul.     

A new oribatid mite of the genus Rhynchoribates (Acari,Rhynchoribatidae) from equador

A new oribatid mite species, Rhynchoribates parafabulosus sp. n., is described from Ecuador. This species is similar to R. fabulosus Beck 1961 (from Peru) in the rostrum structure and the length of prodorsal and notogastral setae. However, it clearly differs from the above species by the absence of thorns on the leg femora, location of adanal lyrifissures, and the structure of notogastral setae.     

A new species of larval Dasitrombium Zhang, 1994 (Acari: Prostigmata: Neothrombiidae) parasitic on grasshoppers fom Nicaragua

A new species of larval neothrombids, Dasitrombium clarissae (Acari: Prostigmata: Neothrombiidae), parasitic on grasshoppers from Nicaragua is described. Larvae have the following diagnostic features: Ta I 110–114, Ti I 48–52, Ta II 102–106, Ti II 44–48, Ip 1020–1054, ratio L/W 1.29–1.40, and the presence on genu I of only two solenidia.     

A new freshwater halacarid mite, genus Peregrinacarus (Halacaridae, Acari) from the Falklands

Peregrinacarus falklandensis n. sp., a halacarid mite from an East Falkland creek, is described and illustrated. This is the second Peregrinacarus species to date. The other species, P. reticulatus Bartsch, is recorded from Marion Island, Indian Ocean. The two species differ in chaetotaxy of the legs. The presence of halacarids in freshwater of southern polar and adjacent regions is discussed.     

Cytological and morphological differences between two species of the genus Tettigonia (Orthoptera,Tettigoniidae) from Korea

Tettigonia ussuriana and T. dolichopoda maritima differ in the length of tegmina, details in venation, and in females in details of the subgenital plate. The two species of the genus Tettigonia have the same number and morphology of autosomes but a different morphology of the X chromosome: in T. ussuriana it is metacentric, whereas in T. dolichopoda maritima acrocentric. In both species, euchromatic zones and breaks of one or to chromatids during meiosis and mitosis in the X chromosome were observed. Additionally, B chromosomes were noted in most individuals of both species.
