Rugonema labiatum n. g., n. sp. (Nematoda: Strongyloidea) from the stomach of Macropus irma (Marsupialia: Macropodidae) from Western Australia

Rugonema labiatum n. g., n. sp. is described from the stomach of Macropus irma (Jourdan) from Western Australia. The new genus possesses four branches to the dorsal ray, has a cylindrical buccal capsule and lacks a cervical groove, placing it within the subfamily Cloacininae Stossich, 1899. The presence of a prominently striated buccal capsule and labial as well as cephalic collars places the genus within the tribe Pharyngostrongylinea Popova, 1952, but it is distinguished from all existing genera within the tribe by the possession of four lips. The presence of lips is an important characteristic of the related tribe Zoniolaiminea (Popova, 1952) and the characters used in distinguishing these two tribes are discussed.     

Corollonema thylogale n. g., n. sp. (Nematoda: Strongyloidea), parasitic in the pademelons Thylogale thetis and T. stigmatica (Marsupialia: Macropodidae) from Queensland, Australia

Corollonema thylogale n. g., n. sp. is described from the stomachs of Thylogale thetis and T. stigmatica from south-eastern Queensland. The new genus is characterised by four branches to the dorsal ray, a J-shaped ovejector, a cylindrical buccal capsule reduced to a posterior, thickened annulus and a leaf-crown of eight elements originating from the base of the buccal capsule. On the basis of these features, the new genus is placed in the subfamily Cloacininae Stossich, 1899 and the tribe Coronostrongylinea Beveridge, 1986. The presence of an internal leaf crown is unique within the tribe and the new genus is erected on this basis.     

Three new species of oxyuroid nematodes,including two new genera,from freshwater catfishes in Brazil

Three new oxyuroid nematode species of the family Pharyngodonidae are described from the intestine of freshwater catfishes in Brazil (River Paraná), two of them being representatives of new monotypic genera: Ichthyouris brasiliensis n. sp. from Pterygoplichthys aculeatus, Brasilnema pimelodellae n. g., n. sp. from Pimelodella gracilis, and Parasynodontisia petterae n. g., n. sp. from Rhinelepis aspera. I. brasiliensis n. sp. differs from the only other congeneric species, I. ro, mainly in the absence of a pair of plate-like structures in the male caudal region, shorter caudal alae, the presence of a pair of conspicuous lateral spines at the level of the anal opening in the female and by other features. Brasilnema n. g. is characterised mainly by a hexagonal oral opening, a broad buccal capsule containing three teeth, a simple spicule and an amphidelphic uterus, whereas Parasynodontisia n. g. is characterised by a triangular oral opening and an amphidelphic uterus in the female; both genera possess six small, triangular, circumoral lamellae slightly raised above the apical surface. The paper includes a key to the pharyngodonid genera whose species are parasitic in fishes.     

Tricalcaria Han gen. nov., a remarkable new genus with three hind‐tibial spurs belonging to the tribe Trichopterygini,with description of a new species from China (Lepidoptera: Geometridae: Larentiinae)

Tricalcaria Han gen. nov. and its type species Tricalcaria stueningi Han sp. nov. are described from China. Morphological characters, including those of the male and female genitalia, are figured. The main diagnostic characters of Tricalcaria are: hind tibia with three spurs in both male and female; ventral margin of costal protrusion bearing a series of long, hook‐like, sclerotized setae in the male genitalia; female papilla analis modified and bearing over part of its surface broad blade‐like sclerotized setae. The wing pattern, venation, and genitalia of this genus are compared with those of the most closely related genera, Tristeirometa Holloway, 1997, Hypocometa Warren, 1896, and Phthonoloba Warren, 1893. Tribal placement is discussed, with the conclusion that the new genus should be placed in the tribe Trichopterygini.     

Deurithitrema gingae n.g., n.sp. (Digenea: Plagiorchioidea) from the kidneys of a salt-water crocodile (Crocodylus porosus Schneider) from Australia

Summary The name Deurithitrema gingae n. g., n. sp. is proposed for worms from the kidneys of one Crocodylus porosus from Darwin, Northern Territory, Australia. The following combination of characters distinguishes the new genus from all others: prepharynx very short; oesophagus absent; caeca reaching to posterior end of body; testes tandem in middle third of body, contiguous or amost so; cirrus-sac large, over-reaches ventral sucker, contains bipartite seminal vesicle, prostatic regions and ejaculatory duct with spines around its opening into genital atrium; genital pore immediately in front of ventral sucker; uterus coiled to posterior end of body; vitellaria lateral from ventral sucker to slightly behind testes; excretory vesicle small, receiving a single ventro-lateral duct from each side behind end of uterine loops. Deurithitrema belongs to the superfamily Plagiorchioidea Dollfus, 1930. It superficially resembles a number of genera, but its relationships within the superfamily are obscure.     

Dictyocaulus capreolus n. sp. (Nematoda: Trichostrongyloidea) from roe deer,Capreolus capreolus and moose,Alces alces in Sweden

Dictyocaulus capreolus n. sp. recovered from roe deer, Capreolus capreolus and moose, Alces alces in Sweden is described and figured. Morphological studies revealed the new species to be closest to D. eckerti and D. africanus on the basis of mouth shape, all three species having an elongate mouth opening. The other species of the genus, including D. viviparus, all have a circular to oval mouth opening. Dictyocaulus capreolus n. sp. can be distinguished from D. eckerti and D. africanus on the basis of the morphology of the buccal capsule and the bursa. These morphological studies support earlier evidence of the presence of a new species of Dictyocaulus in roe deer and moose that could be distinguished from D. eckerti and D. viviparus using either a PCR-linked hybridization assay or image analysis software to study the dimensions of the buccal capsule.     

Hecabolomorpha n. gen., a new Asian genus from the tribe Hecabolini (Hymenoptera: Braconidae: Doryctinae)

A new Oriental genus Hecabolomorpha n. gen. with the type species H. asiatica n. sp. is described and illustrated from India and Central China. The position of this genus in the tribe Hecabolini and its relations with hecaboline genera are discussed.     

Monodelphoxyuris dollmeiri n. g., n. sp. (Nematoda: Oxyurida) from Monodelphis emiliae in Peru

Monodelphoxyuris dollmeiri n. g., n. sp. is described from the caecum of Monodelphis emiliae (Thomas) (Marsupiala: Monodelphidae) collected in the eastern region of the Andes of Peru. M. dollmeiri n. sp. differs from the closest pinworm described from marsupials in the Neotropics (Didelphoxyuris thylamisis Gardner & Hugot, 1995) in having operculate eggs and males that possess a tip prolonged of tail and a different kind of area rugosa. Several other species of pinworms have been described from marsupials in Australia, but all are characterised by possessing of a buccal capsule that is strongly cuticularised with interradial lamellae. These structures are lacking both in M. dollmeiriandD. thylamisis. Monodelphoxyuris n. g. is characterised by a mouth opening into a depression and lateral alae composed of two longitudinal crests. Males possess an area rugosa composed of six ventral sagittal mamelons, a caudal extremity prolonged by a robust tip of the tail which is directed backwards, four pairs of genital papillae (two pairs lateral adanal and sessile, one pair just posterior to the spicule aperture, and the last pair at posterior extremity and pedunculate). Females possess an opisthodelphic uterus, a reflected ovary and operculate, unembryonated, oval eggs.     

Macroponema (Nematoda: Trichonematidae): a new genus from macropod marsupials

A new genus is proposed for two new species, characterised by dorso-ventrally elongate mouth, large lightly sclerotised buccal capsule and long oesophagus with terminal bulb. The two species are distinguished chiefly by characters of the buccal cavity and genital cone.     

Macropostrongyloides dendrolagi n. sp. and Mbaisonema coronatum n. g., n. sp., two new species of nematodes (Strongyloidea: Cloacinidae) from tree-kangaroos,Dendrolagus spp. (Marsupialia: Macropodidae) from Irian Jaya,Indonesia

Two new species of strongyloid nematodes are described from tree-kangaroos, Dendrolagus spp. (Marsupialia: Macropodidae), from Irian Jaya, Indonesia. Macropostrongyloides dendrolagi n. sp. from the colon of Dendrolagus dorianus (type-host) and D. mbaiso is distinguished from congeners by the presence of a cephalic inflation and paired lateral alae which extend along the body from the cephalic inflation. Mbaisonema coronatum n. g., n. sp., from the stomach of D. mbaiso, is allocated to the tribe Coronostrongylinea Beveridge, 1986, as the buccal capsule is reduced to a sclerotised annulus and the lining is inflated into lip-like lobes at the anterior extremity. The new genus is allied to Popovastrongylus Mawson, 1977, from which it is distinguished by the presence of a labial crown composed of numerous elements.     

A new genus and species of myrmecophilous Aleocharini from Morocco (Coleoptera: Staphylinidae: Aleocharinae), associated with Aphaenogaster (Hymenoptera: Formicidae: Myrmicinae)

Aphaenochara lackneri n. gen., n. sp., is described based on material collected from a nest of the ant Aphaenogaster atlantis Santschi in the High Atlas, Morocco. This genus is closely allied to the genus Aleochara Gravenhorst, and is placed in the subtribe Aleocharina of the tribe Aleocharini.     

A new enigmatic apterous cyclostome genus (Hymenoptera: Braconidae) from the Greek Islands

A new West Palaearctic genus Achaiabracon gen. n. with the type species A. aenigmatus sp. n. is described and illustrated from the Greek Islands Crete and Corfu. The position of this genus in the cyclostome group of subfamilies of Braconidae and its possible relation with rhyssaline genera are discussed. A new tribe Achaiabraconini trib. n. is proposed.     

Bartoliella pritchardae n. g., n. sp. (Digenea: Opecoelidae) in Epinephelides armatus (Serranidae) from temperate marine waters of Western Australia

An opecoelid, Bartoliella pritchardae n. g., n. sp., is described from the intestine of Epinephelides armatus from Western Australia. The new genus has been assigned to the subfamily Opecoelininae Gibson & Bray, 1984, bringing the number of genera in the subfamily to two. Although the new genus is similar to Opecoelina Manter, 1934 morphologically, the pedunculate ventral sucker and complete absence of a cirrus-sac necessitate the erection of a new genus. A formal re-definition of the subfamily is given, based on the diagnoses of the genera Opecoelina and Bartoliella n. g.     

New click beetles (Coleoptera: Elateridae) from the cretaceous of Russia and Kazakhstan

A new tribe, two new genera, and seven new species of click beetles are described: Pollostelaterini, trib. nov., Pollostelater baissensis, gen. et sp. nov. from the Lower Cretaceous of Transbaikalia (Baisa locality), five new species in the genus Cryptocoelus Dolin et Nel C. sinitshenkovae, sp. nov. (Romanovka locality), C. shcherbakovi, sp. nov., C. baissensis, sp. nov., C. lukashevichae, sp. nov., C. dolini, sp. nov. (all from Baisa locality), and Turonelater giganteus, gen. et sp. nov. from the Turonian of Southern Kazakhstan (Kzyl-Dzhar locality).

A new tribe, Palaeoerirhinini Legalov, n. tribe, two new genera, Cretotanaos Legalov, n. gen. (type species: Cretotanaosbontsaganensis n. sp.) (Curculionidae: Erirhininae) and Palaeoerirhinus Legalov, n. gen. (type species: Palaeoerirhinusponomarenkoi n. sp. (Brentidae Apioninae) and five new species, C. bontsaganensis Legalov, n. sp., P.latus Legalov, n. sp., P. thompsoni Legalov, n. sp., P. longirostris Legalov, n. sp. and P. ponomarenkoi Legalov, n. sp. from the Bon-Tsagaan locality (Mongolia, Cretaceous, Aptian) are described.http://zoobank.org/3D42DB5C-1841-46F1-A2A0-1034DDE10490     

<Emphasis Type="Italic">Aulacnema monodelphis</Emphasis> n. g., n. sp. and <Emphasis Type="Italic">Angiostoma coloaense</Emphasis> n. sp. (Nematoda: Rhabditida: Angiostomatidae) from terrestrial molluscs of Vietnam

Two species of nematodes, Angiostoma coloaense n. sp. and Aulacnema monodelphis n. g., n. sp. (Angiostomatidae: Rhabditida) are described from terrestrial molluscs of Vietnam. Both species are characterised by a long bowl-shaped buccal cavity and typically angiostomatid male bursal alae, spicules and gubernaculum. The new genus, Aulacnema n. g., is erected for the first reported monodelphic angiostomatid. Angiostoma coloaense n. sp. can be distinguished from other species of Angiostoma Dujardin, 1845 by having a buccal cavity length greater than its width and the absence of tail spikes on both males and females.     

Gall midges of the supertribe stomatosematidi (Diptera, Cecidomyiidae) in the Palaearctic region, with description of new taxa from the Late Eocene Rovno amber: 3. Groveromyia gen. n. analysis of biometric parameters of the recent and late eocene genera and species

The new genus Groveromyia gen. n. was described from the Late Eocene Rovno amber. The genus includes 4 species: G. occlusa sp. n., G. digna sp. n., G. astrosa sp. n., and G. concinna (Fedotova, 2005) comb. n. (Bryocrypta). Some changes in the biometric parameters of the genera and species were revealed relative to those in the recent and the Late Eocene Stomatosematidi. Keys to the recent and fossil genera of the tribe Stomatosematidi and the species of the genus Groveromyia are given.     

Two new taxa of subtribe Rhaconotina (Hymenoptera: Braconidae,Doryctinae, Doryctini) from Africa,with a key to subtribe genera

A new genus, Grangerdoryctes gen. n. (with type species Aivalykus niger Granger), from Madagascar and a new subgenus Pararhacon subgen. n. of the genus Rhaconotus Ruthe (type species R. (P.) haeselbarthi sp. n.) from South Africa are described and illustrated. A discussion of genera without a second radiomedial vein of the fore wing in the tribe Doryctini is presented. The position and content of the subtribe Rhaconotina are discussed and a key for determination of the genera of this subtribe is proposed.     

Scorpidotrema longistipes n. g., n. sp. (Digenea: Opecoelidae) from Scorpis georgiana (Teleostei: Scorpididae) from southern Western Australia

Scorpidotrema longistipes n. g., n. sp. is described from the intestine of Scorpis georgiana Valenciennes (Scorpididae) from off Point Peron, Western Australia. The new genus is distinguished by the combination of a remarkably long and retractable ventral sucker peduncle, a possible uroproct, well-developed cirrus-sac and a uterine seminal receptacle. The subfamilial relationships of the new genus are troublesome. It incorporates features of the Opecoelinae, Stenakrinae and Plagioporinae. The absence of a canalicular seminal receptacle suggests a relationship with the Opecoelinae and Stenakrinae, whereas the well-developed cirrus-sac suggests a relationship with the Plagioporinae and Stenakrinae. The overall arrangement of the gonads is not similar to that of existing genera of Stenakrinae. It is concluded that the genus is best placed in the Stenakrinae although that subfamily may now be an artificial assemblage. This new genus forms part of a distinctive fauna of trematodes restricted to Australian southern temperate fishes.
