A NEW AMPHICYONINE (CARNIVORA: AMPHICYONIDAE) FROM THE UPPER MIOCENE OF BATALLONES-1, MADRID, SPAIN

Abstract:  The vertebrate community of the late Miocene locality of Batallones-1, Madrid Province, Spain, is mainly composed of mammals of the order Carnivora, which represents 98 per cent of the total number of macro-mammal fossils. Here, we describe craniodental remains of approximately 12 individuals of a new, highly specialized member of the Amphicyonidae, previously assigned to Amphicyon sp. cf. A. castellanus . A phylogenetic analysis of Amphicyoninae shows that this new form, named Magericyon anceps gen. et sp. nov., is markedly distinct from all other known Amphicyoninae, specifically in its hypercarnivorous features (strongly compressed upper canines, absence of dP1/dp1 and P2/p2, single-rooted p3, absence of a metaconid on the lower molars, and reduction of M2 relative to M1).     

A new species of Laccognathus (Porolepiform Crossopterygii) from the Devonian of Latvia

A new species of the genus Laccognathus, L. grossi sp. nov., from the upper strata of the Gauja Formation of the Main Devonian Field (Lode locality, Latvia) is established. Morphological similarity and differences of the new species from the previously described L. panderi Gross from the lower strata of the Gauja and the Amata Formation of Latvia are discussed.     

New Tatarian representatives of the subfamily Chaulioditinae (Insecta: Grylloblattida: Chaulioditidae) from European Russia

New Late Permian grylloblattids of the subfamily Chaulioditinae (Chaulioditidae) are described: Chauliodites afonini sp. nov. (Sokovka locality, Vladimir Region; Vyatkian Stage), Ch. gomankovi sp. nov. (Novo-Aleksandrovka locality, Orenburg Region; Severodvinian Stage), and Ch. ponomarenkoi sp. nov. (Isady locality, Vologda Region, upper Severodvinian Stage). Stratigraphic distribution of the subfamily is discussed.     

A new large philisid (Mammalia,Chiroptera, Vespertilionoidea) from the late Early Eocene of Chambi,Tunisia

Abstract: Among the new dental remains from the late Early Eocene of Chambi (Kasserine area, Tunisia) is a large‐sized upper molar of a new bat species, Witwatia sigei nov. sp. (Chiroptera, Vespertilionoidea, Philisidae), described herein. The locality of Chambi has revealed evidence for an early appearance of two modern microchiropteran superfamilies in Africa: Dizzya exsultans, a Philisidae, which is considered to be an archaic Vespertilionoidea, and an indeterminate Rhinolophoidea. In addition to D. exsultans, the new species, W. sigei, is the second representative of the Philisidae in this locality. W. sigei extends back to the late Early Eocene the occurrence of the genus Witwatia, which was previously only reported from the early Late Eocene of the Fayum (BQ‐2, Egypt). By analogy with the largest extant microbats, the large size of Witwatia suggests a tendency to the opportunistic diet of this taxon, thereby contrasting with the strict insectivory characterizing primitive bats found in other continents in the same epoch.     

The Kuehneotheriidae (Mammaliaformes) from Saint-Nicolas-de-Port (Upper Triassic,France): a Systematic Review

The origin and first diversification of mammals in the Upper Triassic remain poorly understood, in part because many fossil discoveries are not fully studied, and in part because the material remains poor. The Saint-Nicolas-de-Port quarry (Rhaetian, France) is the second most important locality that yielded remains of Kuehneotherium, after the fissure-fillings of the Glamorganshire (Lower Jurassic, Wales). This study identifies one new species of Kuehneotherium, K. stanislavi, sp. nov., and a new genus of Kuehneotheriidae, Fluctuodon necmergor, gen. et sp. nov. For these two new species, lower and upper molars are described and the first reconstructions of the postcanine row are proposed. Comparisons with material of Kuehneotherium from other Upper Triassic sites (Syren in Luxembourg, Emborough in England, and Jameson Land in Greenland) suggest two distinct Upper Triassic specific kuehneotheriid assemblages, respectively, west and east of the London Brabant Massif. They also suggest that the extinction event during the Triassic/Jurassic transition did not have a great impact on Kuehneotherium.     

Ademosynoides asiaticus Martynov, 1936, the earliest known member of an extant beetle family (Insecta, Coleoptera, Trachypachidae)

Fossil beetles are described from Kedrovka beds of the locality Babii Kamen’, Kuznetsk Basin, Siberia. According to different authors, this locality is dated to the terminal Permian or basal Triassic. SEM studies have shown that Ademosynoides asiaticus Martynov, 1936, described from this locality, should be placed in the family Trachypachidae, which makes it the earliest known extant family of beetles. In addition to the re-studied holotype, further material is described for this species; a new species of the same genus and a new genus and species of the same family are also described. As a result, almost 10% of the 78 beetle fossils known from this locality are identified as belonging to Trachypachidae. Unfortunately, the study of these beetles is complicated by the rather poor preservation quality and very small size of the majority of the fossils, which usually cannot be properly studied without using SEM. However, even in this case there is no full certainty that the results are absolutely reliable.     

Some American Austrolimnius (Coleoptera: Elmidae)

A key is given to the North American species of Austrolimnius, one of which is described as new. A new species from Venezuela is described, and new locality records in North and South America are listed for previously described species.     

Desmaninae (Talpidae, Mammalia) from the Pliocene of Tollo de Chiclana (Guadix Basin, Southern Spain): Considerations on the phylogeny of the genus Archaeodesmana

The fossil Desmaninae (water-moles) from the Pliocene continental deposits of Tollo de Chiclana (Guadix Basin, Southern Spain) are described. A new species, Archaeodesmana elvirae, is defined from the locality of Tollo de Chiclana-1 (upper Ruscinian). This species is characterized by relatively small canines and premolars (except the P4) and large P4 and molars, besides several morphological features. The presence of Archaeodesmana brailloni is reported from the locality of Tollo de Chiclana-1B (uppermost Ruscinian). A small sample assigned to the genus Archaeodesmana is described from the lower Villafranchian site of Tollo de Chiclana-3, which cannot be determined at the specific level. The phylogenetic relationships between the different species of Archaeodesmana are reconsidered in the light of the recent findings, which support the idea of a more complex phylogeny than previously proposed for this genus. The populations from the Guadix Basin, previously assigned to Dibolia dekkersi (= Archaeodesmana getica), are here considered to belong to a different (unnamed) species, which is the ancestor of A. elvirae. On the other hand, the new species A. elvirae is proposed as the ancestor of A. brailloni.     

Hippotraginae (Bovidae,Artiodactyla, Mammalia) from the Late Miocene of Tuva

Fossil remains of Late Miocene (Baode, NMU10-NMU11) horse antelopes from Tuva (Russia) are described, including Tragoreas sp., Protoryx tuvaensis sp. nov. from the Taralyk Cher locality and Quirliqnoria sp. from the Kholu locality. A new species, Protoryx tuvaensis Dmitrieva et Serdyuk, is described. These taxa compose a Late Miocene antelope assemblage of a new eastern geographical point (Russia, Tuva, Baode, NMU10-MN11).     

New jewel beetles (Coleoptera: Buprestidae) from the Cretaceous of Russia,Kazakhstan, and Mongolia

A new jewel beetle genus, with one species (Cretofrontolina kzyldzharica gen. et sp. nov.) from the Upper Cretaceous of Kazakhstan is described based on a body; and three new species of the formal genus Metabuprestium are described based on isolated elytra: Metabuprestium sibiricum sp. nov. and M. arkagalense sp. nov. come from the Arkagala locality (Upper Cretaceous of Russia) and M. ichbogdense sp. nov. is from the Shar Tologoi locality (Lower Cretaceous of Mongolia).     

A new species of Karydomys (Rodentia, Mammalia) and a systematic re-evaluation of this rare Eurasian Miocene hamster

We describe a new species of the rare and enigmatic cricetid genus Karydomys from the middle Miocene Ville Formation of the Hambach lignite mine in north-west Germany. The locality Hambach 6C has yielded the first substantial records of Karydomys from central Europe. For the first time, all molar positions are well-documented, including the previously unknown m2. The excellent molar material allows us to distinguish Karydomys wigharti sp. nov. from the western European species K. zapfei. Karydomys wigharti predominantly occurs at localities that are correlated with the upper part of the Mammalian Neogene biozone MN 5. The new finds are of palaeobiogeographic significance for the genus Karydomys , since Hambach 6C represents the north-westernmost outpost of terrestrial Miocene faunas in Europe. In addition, the locality has yielded the first lower jaws and incisors of the genus. Both the jaw morphology, and the ornamentation and microstructure of the incisor enamel offer new arguments for a systematic classification of Karydomys into the subfamily Democricetodontinae. We assume that the scarcity of the two large European Karydomys species can be explained by their special adaptation to wet habitats, which are poorly documented in the fossil record.     

Earliest occurrence of Puma pardoides (Owen, 1846) (Carnivora,Felidae) at the Plio/Pleistocene transition in western Europe: New evidence from the Middle Villafranchian assemblage of Montopoli,Italy

The puma-like cat Puma pardoides (Owen, 1846) is reported from several Eurasian localities dated to the Late Pliocene–Early Pleistocene, but its Italian fossil record is really poor; in fact, the only possible occurrence comprises some fragmentary postcranial material from the Late Villafranchian locality of Pirro Nord (1.6–1.3 Ma). In the present paper, we describe an isolated left upper carnassial of a medium-sized felid belonging to the collection of fossil mammals from Montopoli (Tuscany, Italy), the type locality of the Middle Villafranchian Faunal Unit (∼2.6 Ma). All the morphological and morphometric characters of the tooth are consistent with an attribution to Puma pardoides (Owen, 1846), which comes out as the second felid species from Montopoli together with Acinonyx pardinensis (Croizet et Jobert, 1828) and is, possibly with the specimens from Perrier-Étouaries, the earliest occurrence in western Europe.     

Commensal Leucothoidae (Crustacea, Amphipoda) of the Ryukyu Archipelago, Japan. Part III: coral rubble-dwellers

Commensal leucothoid amphipods have been collected from coral rubble samples throughout the Ryukyu Archipelago, Japan. Seven new species are described in two generawith valuable location data. A new locality is presented for Paranamixis misakiensis Thomas, 1997. An identification key to all described Leucothoidae of the Ryukyu Archipelago is provided.

Revision of the Trichosirocalus horridus (Panzer) species complex, with description of two new species infesting thistles (Coleoptera: Curculionidae, Ceutorhynchinae)

Abstract The Trichosirocalus horridus (Panzer) species complex is defined and revised and two new sibling species are described and figured: T. briesei (type locality: San Esteban de Gormaz, Soria, Spain) and T. mortadelo (type locality: Canberra, Australia, introduced). The existence of these siblings could explain the different food preferences observed between the different populations or strains of the supposed single species T. horridus .     

Notes on the systematics and distribution of Palaearctic blues (Lepidoptera,Lycaenidae)

Two new species and one new subspecies of blues are described from Central Asia, namely Polyommatus kuronjerus Korb, sp. n. (type locality: Kyrgyzstan, the Suusamyr valley, 7 km E of Suusamyr, 2800 m), Neolycaena turkomana Korb, sp. n. (type locality: Turkmenia, Badkhyz Nature Reserve, the Kyzyldzhar valley) and Satyrium acaudatum balasagyna Korb, ssp. n. (type locality: Kyrgyzstan, the Kyrghyz Mts., Tatyr, Golubinyi Waterfall, 1200 m). A new location for Plebejidea elvira (Eversmann, 1854) is determined for the Boomskoye valley in the Kyrghyz Mts. This new location is related to the late Pleistocene refuge in the Issyk-Kul valley.     

The parrots (Aves: Psittaciformes) from the Middle Miocene of Sansan (Gers,Southern France)

The occurrence of Archaeopsittacus sp. (Psittaciformes) in the fossil deposits of Sansan (France) is reported, testifying to a survival of this genus in the Middle Miocene, as Archaeopsittacus verreauxi was described from the Early Miocene of Saint-Gérand-le-Puy (France) and was recorded only from its type locality. The data discussed here indicate the presence of two parrot species from Sansan, as it is the type locality of another parrot species, Pararallus dispar, only known from this locality. The differences between the humeri of these two taxa are described in detail, together with the differences from the other European fossil parrot species. The presence of more than one species of parrot in the same locality is not rare, but in Europe it is recorded in Sansan for the second time. Evidence for parrots also confirms the paleoenvironmental reconstruction of Sansan, as parrots are primarily arboreal species. Archaeopsittacus also represents one of the few common elements between the Early and Middle Miocene European bird assemblages.
