New species of the Hygrobates salamandrarum-group (Acari, Hydrachnidia, Hygrobatidae) from Southeast Asia

Two new water mite species of the genus Hygrobates Koch, 1837 (Acari, Hydrachnidia, Hygrobatidae) were found to live parasitic on newts of the genus Paramesotriton Chang, 1935 (Amphibia, Caudata, Salamandridae) from Vietnam and Laos: Hygrobates forcipifer sp. nov. and H. ancistrophorus sp. nov. The H. salamandrarum-group is defined, that now includes three species from Southeast Asia.

First record of the genus Leluthia Cameron, 1887 (Hymenoptera: Braconidae,Doryctinae) in the Oriental region with description of two new species from India

The genus Leluthia Cameron, 1887 is recorded for the first time from the Oriental region. Two new species, Leluthia (Euhecabolodes) areola Ranjith et Belokobylskij, sp. nov. and L.(E.) indica Belokobylskij et Ranjith, sp. nov. are described and illustrated from the Indian states Kerala and Goa, respectively. The new species are most similar to the Western Palaearctic Hecabolus hungaricus (Szépligeti, 1900), which is reinstated from its synonymy with Polystenus and transferred to the genus Leluthia Cameron (stat. resurr. and comb. nov.).     

Two new species of Stenoloba (Lepidoptera: Noctuidae) from East Asia with the first description of S. nora female genitalia

Two new species of Stenoloba Staudinger, 1892 are described: S. ronkayi Sohn and Tzuoo sp. nov. from Taiwan and S. hystrix Sohn sp. nov. from northern Vietnam. The relationships of the new species with the actual species groups of Stenoloba are discussed. The formerly unknown female of S. nora Kononenko and Ronkay, 2001 and its genitalia are described here for the first time.     

Tettigarctidae (Insecta: Hemiptera: Cicadoidea) from the Middle Jurassic of Inner Mongolia, China

Three new species of Tettigarctidae from the Middle Jurassic of Daohugou, China are described: Shuraboprosbole daohugouensis nov. sp., S. minuta nov. sp., and S. media nov. sp. The revised diagnostic characters of Shuraboprosbole Becker-Migdisova are provided based on well-preserved whole-bodied fossil tettigarctids. So far, only four definitive species of Tettigarctidae are recorded from the Mesozoic of China. The pronotum concealing major of mesonotum seems to be an autapomorphy of Tettigarctinae. The “cicadellid-like tarsi” found in Cicadellidae and Brazilian Tettigarctidae are probably a parallel evolution.

Sélaciens nouveaux du London Clay de l'Essex (Yprésien du bassin de Londres)

The Ypresian locality of Burnham-on-Crouch(Essex) has yielded numerous Selachian species, some of which are new: Hexanchus agassizi sp. nov., Scyliorhinus burnhamensis sp. nov., S. casieri sp. nov., S. pattersoni sp. nov., S. woodwardi sp. nov., Pararhincodon ypresiensis sp. nov., Triakis wardi sp. nov., Mustelus whitei sp. nov. The Hexanchid teeth classicaly refered to Notidanus serratissimusAg. include in fact two separate species belonging to different genera: Notorhynchus serratissimus (Ag.) and Hexanchus agassizi sp. nov. Lamna affinis (Casier) is arranged in the genus Isurolamna nov. in consideration of his dental peculiarities. The genus Burnhamia nov. is created for Rhinoptera daviesiWoodward that can be regarded as a Mobulid. Oxyrhina sheppeyensisCasier must be classified in the genus Anomotodon. The genus Triakis, Mustelus, Anomotodon and Pararhincodon are pointed out for the first time in the Ypresian.     

New fossil insects (Diaphanopterodea: Martynoviidae) from the Lower Permian of the Boskovice Basin, southern Moravia

Two new genera and new species assigned to the family Martynoviidae (Diaphanopterodea), Boskovicia celtai nov. gen., nov. sp. and Moravoptera hladilovae nov. gen., nov. sp. are described and illustrated from the Lower Permian (Artinskian/Sakmarian) locality of Obora, southern Moravia (Czech Republic). Discovery of the species Martynovia insignis Tillyard, originally described from the Lower Permian of Kansas (USA), supports close relationship of both faunas across Euramerica.     

Two new species of Electra (Bryozoa, Cheilostomata) from the Miocene of the Aquitaine Basin, France

Post-Cretaceous examples of Electridae, a primitive family of cheilostome bryozoans, are poorly represented in the fossil record, probably because of their thinly calcified zooids and preference for nearshore environments. Two new electrid species are here described from the Lower Miocene (Burdigalian) of Pontpourquey, Aquitaine, France: Electra triaurata nov. sp. and Electra aquitanica nov. sp. Both species belong to extant species groups, the E. indica and E. biscuta groups, respectively, that presently occur in the Indo-Pacific; both are the only fossil examples of these species groups. Whereas E. triaurata nov. sp. has uniserial colonies, zooids with porous gymnocysts, three flattened spines and basal windows allowing etching of the substrate to produce the trace fossil Leptichnus, E. aquitanica nov. sp. has multiserial colonies and zooids with a proximal gymnocyst bearing 2 to 5 spines.     

New species of Atomaria Stephens, 1829 (Coleoptera,Cryptophagidae) from China and Taiwan

New records for China and Taiwan are added: Atomaria (Atomaria) klapperichi Johnson, 1971 and Atomaria (Atomaria) plecta Lyubarsky, 1995. New subgeneric combinations are proposed for Atomaria (Atomaria) klapperichi, Atomaria (Atomaria) plecta and Atomaria (Atomaria) torrida Johnson, 1971.LSID: urn:lsid:zoobank.org:pub:6A3DCCBE-8978-4D2C-B366-56C9ECEA51A4.

In this study, a total of eight fossorial aculeate wasps of the tiphiid genus Mesa Saussure, 1892 from China are revised, including two new species, viz., Mesa hongchibaensis sp. nov., and Mesa glaber sp. nov.. The following species Mesa dimidiata (Guérin-Méneville, 1837) and Mesa nursei (Turner, 1909) are newly recorded from China. The male specimen of Mesa formosensis Tsuneki (1986) is firstly found. In addition, an updated key to the Oriental species of the genus is provided.     

Fossil representatives of the family Greenideidae (Hemiptera, Aphidoidea) from the Miocene of Europe

Four new aphid species (Hemiptera, Aphidoidea, Greenideidae) are described on the basis of imprints in oil-shales from the Miocene of Europe (Rubielos de Mora, Spain; Vishnevaya Balka ?Stavropol?, Russia): Eutrichosiphum europaeum nov. sp., Greenidea hispanica nov. sp., Greenideoida (Pentatrichosiphum) turolensis nov. sp. and Mollitrichosiphum rubusensis nov. sp. All the taxa are placed within recent genera of the subfamily Greenideinae. Miocene representatives of this subfamily have been found in the south of Europe. Later changes of climatic conditions limited its geographic range to south-eastern Asia, where it is now represented by over 130 species of seven genera.     

Hamatopeduncularia Yamaguti, 1953 (Monogenea: Ancylodiscoididae) from catfish off Peninsular Malaysia: Description of two new species and insights on the genus.

Hamatopeduncularia longiangusticirrata sp. nov. and H. petalumvaginata sp. nov. were collected from Arius maculatus and Nemapteryx caelata, respectively from Tanjung Karang, Peninsular Malaysia. Morphological and molecular investigations were carried out to ascertain the identity of the new species. The two new species differ from previously described Hamatopeduncularia species in the morphology of the male and female reproductive organs. Hamatopeduncularia longiangusticirrata sp. nov. possesses a long penis similar to H. elongata, H. longicopulatrix, H. brisbanensis, H. major and H. petalumvaginata sp. nov., but differs in having a thread-like tapering distal end and can be distinguished from H. brisbanensis and H. major in not having an accessory piece. Hamatopeduncularia longiangusticirrata sp. nov. is also unique in having an ornamented penis initial and a vaginal tube surrounded by fine hair-like structures. Hamatopeduncularia petalumvaginata sp. nov. possesses a simple penis without an accessory piece and a petaloid vaginal opening that resembles the arrangement of petals on a flower. Maximum likelihood trees were constructed from partial 28S and 18S rDNA sequences of the two new species and other ancylodiscoidids to reveal a strongly supported monophyletic branch consisting of the two new species for both markers. According to Lim's classification in 1996 of Hamatopeduncularia species penis type, H. petalumvaginata sp. nov. has been classified within the elegans-type and H. longiangusticirrata sp. nov. is proposed as the longiangusticirrata-type.
