† Pyrenicocephalus jarzembowskii, gen. et sp. n. (Hemiptera: Heteroptera: Enicocephalomorpha: Enicocephalidae: Enicocephalinae) from Early Eocene, London Clay, England, Isle of Sheppey, is described and illustrated according to the unique pyritized adult head reported as a larval enicocephalid head by Jarzembowski (1986). The head anatomy of similar and related genera of Enicocephalinae is compared and the close relationship of the new genus to a clade including the extant genera Oncylocotis, Embolorrhinus and Hoplitocoris is suggested, most probably as the sister genus to Hoplitocoris (presently with Afrotropical, East Palaearctic and Oriental range).
Four of 28 wild boodies or burrowing bettongs, Bettongia lesueur (Quoy et Gaimard) passed oocysts of species of Eimeria Schneider, 1875. The boodies are surviving on off-shore islands and in large predator-proof sanctuaries on the mainland where they were reintroduced. The boodie is a potoroid marsupial extinct from the mainland of Australia due to predation from red foxes and feral cats. Comparison with other species of the genus Eimeria indicates that the coccidium found represents a new species. Sporulated oocyst of Eimeria burdi sp. n. are pyriform, 21.0-24.0 µm (mean 22.6 µm) by 14.0-16.0 µm (14.9 µm), with a length/width ratio 1.31-1.71 (1.52) and 1-µm-thick yellowish bilayered wall. Micropyle is present at the thinner apex end filled with hyaline body. Polar granules are absent. Sporocysts are ellipsoidal, 10.0-13.5 µm (11.8 µm) by 7.0-8.5 µm (7.4 µm), shape index is 1.42-1.89 (1.63) and a very thin, poorly defined unilayered sporocyst wall is 0.2 µm thick with a domelike almost indistinct Stieda body. Substieda body is indistinct., Frances Hulst, Leah F. Kemp, Jan Šlapeta., and Obsahuje bibliografii
One new genus and seven new species of Phoridae (Diptera) are described from Bialowieska Forest in Poland, namely Poloniphora Disney & Durska gen, n. with the species P. bialoviensis Disney sp. n., Megaselia henrydisneyi Durska sp. n., M. joannae Disney sp. n., M. marekdurskii Disney sp. n., M. teresamajewskae Disney sp. n.: M. trojani Disney sp. n., Phora michali Disney sp. n., The new genus shows affinity with Australasian genera, Beckerina Malloch and Eocene fossils erroneously assigned to Megaselia in the past.
One new genus and nine new species of Staphylinidae are described from Baltic amber, namely Palaeosepedophilus gen.n. and the species P. succinicus sp.n., Lathrobium balticum sp.n., Lathrobium succini sp.n., Lathrobium ambricum sp.n., Lathrobium jantaricum sp.n., Sepedophilus balticus sp.n., Dictyon antiquus sp.n., Phymatura electrica sp.n., Aleochara baltica sp.n. Their affinity with related species is discussed.
A new genus and new species, Angulonotus grisescens, is described from Kazakhstan and Uzbekistan and its taxonomic placement within the tribe Orthotylini is discussed. Illustrations of male and female genitalia, micrographs of selected characters, photographs of dorsal habitus, hosts and distributional records of this new taxon are provided. Comparisons are made with species of the genus Hyoidea Reuter, 1876., Alexander A. Knyshov, Fedor V. Konstantinov., and Obsahuje seznam literatury
A new species group and five new species of mites of the genus Pavania Lombardini, 1949 belonging to the family Dolichocybidae (Acari: Heterostigmata) are described from Iran. Pavania gymnopleuri Hajiqanbar & Khaustov sp. n., P. sabzevarensis Hajiqanbar & Khaustov sp. n. and P. onthophagi Hajiqanbar & Khaustov sp. n., represent a new gymnopleuri species group. Two new species are also described in the fusiformis group: P. kamalii Hajiqanbar & Khaustov sp. n. and P. elongata Hajiqanbar & Khaustov sp. n. All new species are associated with scarabaeid and carabid beetles (Coleoptera: Scarabaeidae, Carabidae). This is the first record of the family Dolichocybidae from Iran. The leg setation and geographic distribution of all genera of this family are discussed and keys to genera and species of the genus Pavania are provided.
Fianoniella stenognatha sp. n. from the Columbretes Islands (Castellón, Spain) is described and illustrated. The new species is distinguished by its longer and narrower mandibles with parallel or divergent rims in the apical half, wider clypeus, hind ocelli more separated and closer to the eyes, and longer flagellar segments. Additional notes to complete the original description of the closest species, F. laeviscutum (Horstmann), are given. A key to the European species of Fianoniella is provided.
A new nematode species, Paracapillaroides acanthocotylus sp. n., is described from the marine fish Nemadactylus bergi (Norman) (Latridae, Perciformes) from waters off Mar del Plata, Argentina (38°08'S, 57°32'W) (prevalence 81.8%, mean intensity 12.4 ± 10.3). The new species is readily distinguished from P. agonostomi Moravec, Salgado-Maldonado et Caspeta-Mandujano, 1999, the only known species of the genus, by having in both sexes a longer oesophagus in relation to total body length. Males of the new species have a shorter and more complex spicule and a markedly different morphology of the spicular sheath; the rays supporting the caudal bursa are also shorter and rounded, instead of digitiform. Furthermore, females of the new species have elevated vulval lips and longer eggs. The complex structure of both the spicule and spicular sheath is unique among all capillariids parasitizing cold-blooded vertebrates. This is the first record of a species of Paracapillaroides in the southwestern Atlantic Ocean.
Rhinozachvatkinia calonectris sp. n., a new species of the feather mite genus Rhinozachvatkinia Mironov, 1989 (Avenzoariidae: Bonnetellinae), is described from two species of shearwaters in the North-East of the Atlantic Ocean, Calonectris edwardsii (Oustalet) (type host) and Calonectris borealis (Cory) (Procellariiformes: Procellariidae). We completed the morphological description of this new feather mite species with sequence data on the mitochondrial cytochrome c oxidase subunit I gene fragment (COI). The full generic status of Rhinozachvatkinia, originally established as a subgenus of Zachvatkinia Dubinin, 1949, is formally fixed and its systematic relationships are briefly discussed.
A new subgenus Leasphaericus (of Sphaericus) with two new species, S. (L.) flavipennis and S. (L.) diversevillosus, are described from North West Cape and Barrow Island, in Western Australia. With the exception of one anthropophilous and paracosmopolitan species, the genus Sphaericus had been recorded only from the southern Palaearctic area. The discovery of Australian autochthonous Sphaericus suggests that this genus may be more diversified in other areas, namely in Africa.
