Two Lepotrema Ozaki, 1932 species (Digenea: Lepocreadiidae) from marine fishes from the southern Great Barrier Reef, Queensland, Australia

The genus Lepotrema Ozaki, 1932 is revived and redefined. Its main diagnostic characters are the dorsal excretory pore, the muscular development of the distal metraterm and the trilobate ovary. It is considered to contain five species, to which a key is given. Lepotrema clavatum Ozaki, 1932 is briefly redescribed from Amanses scopas and Sufflamen chrysopterus, and L. canthescheni n. sp. is described from Cantheschenia grandisquamis, based on material from the southern Great Barrier Reef. L. canthescheni is distinguished by its vitelline and uterine distribution. The other three recognised species are: L. adlardi (Bray, Cribb & Barker, 1993) n. comb., L. incisum (Hanson, 1955) n. comb. and L. xanthichthydis (Yamaguti, 1970) n. comb., all three having originally been placed in Lepocreadium.     

A cladistic analysis of Erythracarinae (Acarina: Prostigmata: Anystidae), with the description of a new genus

A cladistic analysis of sixty erythracarine species is presented and used to justify recent nomenclatorial changes to the classification of erythracarine genera. Erythracarinae is redescribed, and a new diagnosis for the subfamily and a key to the included genera are presented. Neotarsolarcus is recognized as a junior synonym of Tarsolarkus, which is recorded for the first time from North America. A new genus, Pedidromus, with six new species (P. agitatus sp.n. P. curiosus sp.n., P. durongensis sp.n., P. peliculus sp.n., P. pilotrix sp.n., P. velox sp.n.) is described.     

Taxonomic study of the genus Dichrogaster Doumerc (Hymenoptera: Ichneumonidae: Cryptinae) in Japan

Japanese species of the genus Dichrogaster are revised. Four species are recognized. Two species, D. imperialis n. sp. and D. parva n. sp., are described. Dichrogaster liostylus (Thomson) and D. kichijoi (Uchida) are redescribed. A key to the Japanese species is provided.     

Six new species of the genus Diplopeltula (Nematoda: Diplopeltidae) with remarks on the heterogeneity of the taxon

Six new Diplopeltula species are described: D. pulchra sp.n., D. belgica sp.n., D. striolata sp.n. and D. curta sp.n. (Southern Bight of the North Sea), D. nellyae sp.n. and S. pumila sp.n. (New Caledonia). Diplopeltula indica Gerlach, 1962 is redescribed from Guadeloupe (FWI). Based on the examination of these seven Diplopeltula species, the genus has been reappraised. The systematic position of the other genera of the Diplopeltidae Filipjev, 1918 is also discussed. Diplopeltoides Gerlach, 1962 is moved from the Aegialoalaimidae Lorenzen, 1981 to the Diplopeltidae.     

Additions and corrections to “The Muscidae of Central Europe” II. Two new species of Spilogona (Diptera, Muscidae)

Two species of Spilogona, S. angustigena sp. n. and S. tatrica sp. n., are described from the Czech Republic and Slovakia, respectively. Both species are characterised by a gynaecomorphic shape of the male head, i.e., by a broad frons and the presence of a pair of orbital setae. Three species with this type of head are already known in the Palaearctic region: S. karelica (Tiensuu, 1935) from Russian Karelia, S. lapponica (Ringdahl, 1932) occurring in Norway and Sweden and redescribed here from material collected recently in Russia and Sweden, and S. spinicosta (Stein, 1907) from Tibet. All five species are compared and a new identification key is given. Apart from the external similarity of the male heads, the species under study are hardly closely related and their dichoptic heads may be explained as a homoplasy among similar ecomorpha.     

The Discocriconemella species of the Fiji Islands (Nematoda: Criconematoidea)

Summary Two species of Discocriconemella, one new and one previously described, were found in the Fiji Islands. D. caudaventer n.sp., from the rhizosphere of cocoa, Theobroma cacao L., is characterized by its reflexed tail and shape of the tail terminus. D. discolabia (Diab & Jenkins, 1966) de Grisse, 1967 is redescribed from the Fijian populations, the male for the first time.     

Siteroptes (Siteroptoides) species with Pediculaster-like phoretomorphs (Acari: Tarsonemida: Pygmephoridae) from New Zealand and Polynesia

Abstract

Six species of Siteroptes subgenus Siteroptoides—kneeboni (Wicht), mesembrinae (Canestrini), microsaniae n.sp., morelliae (Rack), muscarius n.sp., and portatus n.sp.—have been found in New Zealand. S. (S.) mesembrinae occurs on Niue Island also, and a further new species, pacificus, is recorded from Tonga. The phoretomorph females of all 7 species, the normal females of 4, the males of 3, and larvae of 2 are described and compared. The similarities and differences between normal and phoretomorph females are particularly noted. Besides kneeboni, 2 species described by Wicht but not occuring in New Zealand—athiasae and flechtmanni— are redescribed from type material and transferred to Siteroptes (Siteroptoides). Keys are given for normal females and Pediculaster-like phoretomorph females of Siteroptoides. Siteroptes mesembrinae subsimilis and S. ignotus altaicus are raised to species status. Diagnostically important measurements are given to help define the variation within and between species and morphs.     

Phylogenetic revision of Bonjeania Irwin & Lyneborg (Diptera: Therevidae)

The endemic Australian genus Bonjeania Irwin & Lyneborg is revised. Seven species are described as new: B. angelikae sp.n., B. clamosis sp.n., B. dynastis sp.n., B. flavofemoralis sp.n., B. irwinae sp.n., B. orphne sp.n. and B. trilineata sp.n. Three species, B. actuosa (White), B. nitidifrons (Macquart) and B. segnis (White), are redescribed. All species of Bonjeania were compared in a cladistic analysis with Agapophytus albobasalis Mann and five exemplars of the speciose sister genus Parapsilocephala Kröber, and the phylogenetic relationships of Bonjeania discussed. The male genitalic musculature of B. clamosis sp.n. is described and figured, and discussed with respect to previous studies on other Therevidae.     

To the knowledge of the leaf-beetle tribe Nodinini (Coleoptera,Chrysomelidae, Eumolpinae) from the Philippines and Borneo

Three new species of the genus Tricliona are described from the Philippines and Borneo Island: T. bakeri sp. n., T. sandakana sp. n., and T. philippina sp. n. Stethotes aedilis Weise are transferred to the genus Cleoporus, and Stethotes ferruginea Weise, to Tricliona. Typophorus quadrimaculatus Baly is transferred to Cleoporus, and C. cruciatus Lefèvre is synonymized with it. The genus Coniomma Weise is redescribed. For each species, drawings of the genitalia are provided. The species of Cleoporus from the Philippines and all the species of the Tricliona ferruginea group are keyed.     

The Neotropical genus Anaisus (Elateridae) and its relationship to the Pyrophorinae

Four species of the genus Anaissus Candeze are recognized and described or redescribed and a key for their identification is given; anandra sp.n., aurantium spn., fuscipes sp.n. and tarsalis Candeze (=spinipennis syn.n.). A new subgenus Auctumnalis is erected with aurantium as type-species. Two possible species from Brazil and French Guiana respectively are also reported. The systematic position of the genus is discussed in relation to the Neotropical Pyrophorinae, and on the basis of adult characters Anaissus is here assigned to the subfamily Pyrophorinae.     

Contribution to the knowledge of the leaf-beetle fauna (Coleoptera,Chrysomelidae) of Eastern Kazakhstan

Chrysolina undulata asperata Lopatin is promoted to the species Chrysolina asperata Lop., stat. n., and is redescribed. A new species, Chrysolina tatianae Mikhailov sp. n. closely related to Ch. ordinata Gebl., is described from the Narymo-Bukhtarminskaya Depression, based on the adults and 2nd-instar larva. New data on the ecology and distribution of Chrysolina kabaki Lop., Ch. katonica Lop., and Ch. oirota Lop. are given.     

The New World species of the water-beetle genus Notomicrus (Noteridae)*

Eight species of Notomicrus Sharp are recognized and described or partially redescribed with figures of dorsal outlines and external male genitalia: brevicomis Sharp, gracilipes Sharp, huttoni sp.n., malkini sp.n., nanulus (LeConte), reticulatus Zimmermann, sharpi Balfour-Browne, traili Sharp. A key for identification is given, but the main reliance for recognition of the species is on the external male genitalia. New distribution records are given for all species.     

Three New Species of the Genus Alulatettix Liang from China (Orthoptera: Tetrigidae)

Characters of the tetrigid genus Alulatettix Liang are redescribed. Three new species, Alulatettix nigromarginalis n. sp., Alulatettix flavotibialis n. sp., and Alulatettix tianzhushanensis n. sp., are described. An updated key to the species of this genus is provided.     

New data on the genus <Emphasis Type="Italic">Neostylopyga</Emphasis> Shelford, 1911 (Dictyoptera,Blattidae) with description of a new species from Laos

A new species of the genus Neostylopyga Shelford, 1911, N. laosana sp. n., is described from Laos, and the male genitalia are examined in detail. The type species of the genus Neostylopyga, N. rhombifolia (Stoll, 1813), is redescribed, and the taxonomic position of the genus is discussed.     

Leptosomatides brevicaudatus n. sp. and a Redescription of Leptosomatides marinae Platonova, 1967 (Enoplida: Leptosomatidae)

The free-living marine nematodes Leptosomatides brevicaudatus n. sp. and L. marinae were described and redescribed, respectively, from material collected in the northwest Pacific. Leptosomatides brevicaudatus n. sp. from Simushir Island differs from L. marinae in the ratio c8 (body length divided by tail length measured on the chord) and the length of the spicules. Leptosomatides marinae is redescribed from light microscopy (LM) observations of the type specimens and LM and scanning electron microscopy (SEM) observations of specimens from Hokkaido, Japan. It appears to be impossible to distinguish among some species of Leptosomatides because they are either insufficiently described or known only from females. Secondary sexual characters of males are essential for purposes of identification.

Bharatatelura malabarica Mendes is reported for the first time off the Indian sub-continent (in Suva). Proatelura jacobsoni Silvestri is recorded in Macao (southern China) and in the Moluccas islands and notes are presented on its male sex. Gastrotheus (Lasiotheus) nanus (Escherich) is found for the very first time in Macao, in Cook islands and in Niue. Identification keys are provided to Protrinemuridae genera and to species of Trinemurodes, and modifications are suggested to previously presented keys to Nicoletiidae genera and to Lepidospora and Metrinura species.     

New gall midges of the tribe Leptosynini (Diptera,Cecidomyiidae) from the Late Eocene ambers and the classification of the supertribe Heteropezidi

Three new genera and 27 new species of gall midges are described from the Late Eocene ambers: Henria baltica sp. nov., Frirenia manca sp. nov., F. musicata sp. nov., Leptosyna samlandica sp. nov., L. fastosa sp. nov. from Baltic amber and H. xystica sp. nov., H. liquida sp. nov., Stellasegna vlaskini gen. et sp. nov., S. vaporea sp. nov., S. nexa sp. nov., Rasnitsia verticosa gen. et sp. nov., F. rohdendorfi sp. nov., F. schevchenkoi sp. nov., F. melica sp. nov., F. lukashevichae sp. nov., F. leporidis sp. nov., F. marmarygma sp. nov., F. vesana sp. nov., Vincinescia alisae gen. et sp. nov., L. margarita sp. nov., L. munifera sp. nov., L. sukachevae sp. nov., L. assa sp. nov., L. larga sp. nov., L. vegeta sp. nov., L. vaticina sp. nov., and L. shcherbakovi sp. nov. from Rovno amber. Strobliella capitata Fedotova is redescribed as Henria capitata (Fedotova, 2004) (comb. nov.). Diagnoses of Henria (= Electroxylomyia Nel et Prokop, syn. nov.), Frirenia, and Leptosyna are revised. As a result, Henria comprises 3 extant and 5 extinct (Late Eocene) species, including H. eocenica (Nel et Prokop), comb. nov. (= Electroxylomyia eocenica), Frirenia comprises 1 extant and 10 Late Eocene species, and Leptosyna comprises 3 extant and 11 Late Eocene species. The tribe Heteropezini is elevated to the supertribal rank (Heteropezidi) and included in the subfamily Lasiopterinae. Leptosynini is treated as a separate tribe, and Lasiopterinae is considered as part of Cecidomyiidae s. str. (i.e., excluding Lestremiidae). Keys to the tribes and genera of Heteropezidi and to species of Henria, Stellasegna, Frirenia, and Leptosyna are provided. The gall midge faunas of the Rovno and Baltic ambers are compared. Phylogenetic relationships within the supertribe are hypothesized.     

Monograph of the solenofilomorphidae (Turbellaria: Acoela)

Morphological studies of eleven new species in the family permitted reconstruction of progressive evolutionary lines, and this strongly implies progressive evolutionary lines for other acoela. Solenofilomorpha funilis n. sp., Myopea crassula n. g. n. sp., M. latafaucium n. sp., Fusantrum rhammiphorum n. g. n. sp. and Endocincta punctata n. g. n. sp. are described from the coast of South Carolina, U.S.A., and S. guaymensis n. sp. is described from the Gulf of California. Five additional unnamed species from the U. S. Pacific Coast, Sweden and Tunisia are briefly described. Two species groupings were based on correlation between two different arrangements of pharynx muscles and trio arrangements of antrum muscles and further correlations with lesser characters. The membership of the two groupings in a single family make it clear that evolution proceeded by addition of structures to a less complex common ancestor. Functional and behavioral considerations support the evolutionary path drawn from morphology. Distinctive statocyst structure, ciliary interconnections and sperm morphology shared by acoels show them to have a common ancestry, but clearly different pharynges and male structures cannot be consistent with evolution by reductions. A common ancestor of low complexity has probably given rise to several partly parallel evolutionary lines which together form the structurally diverse Acoela. The history of acoel systematics is also briefly summarized.
