New taxa in Psoroptinae. Hypothesis on the origin of the group (Acarina, Sarcoptiformes, Psoroptidae)]

The author describes three new species and one new genus in the family Psoroptidae, subfamily Psoroptinae. A key is given to all the known genera of this subfamily. The fact that amongst the 16 species known from Africa South of the Sahara, 9 are endemic incites the author to believe that this group has a Centro-african origin.     

Improved tribal delimitation of the subfamily Dictyopharinae and description of new genera and new species (Homoptera,Fulgoroidea, Dictyopharidae)

Ten new genera, five new subgenera, and five new species are described in the family Dictyopharidae. Three generic names are synonymized. A new name is proposed for the generic homonym. Dictyophara kazeruna Dlabola is transferred to the genus Callodictya Melichar. The genus Sinodictya Matsumura, with the type species Sinodictya tukana Matsumura, is redescribed. A new key to the tribes of the subfamily Dictyopharinae is given. The composition and characters of the tribes Taosini and Lappidini are revised. All the genera of the subfamily Dictyopharinae are listed according to their tribal position. New records are given for some interesting species.

The millipede genus Tetracentrosternus Pocock, 1895 (Polydesmida,Paradoxosomatidae, Alogolykinae,Alogolykini), with a description of the first,new species from Thailand

The millipede subfamily Alogolykinae and the tribe Alogolykini are recorded in Thailand for the first time,being represented there by Tetracentrosternus theelorsuensis sp. n. While the new species has characteristics that place it in the genus Tetracentrosternus, it also shows a number of unique features that make it necessary to rediagnose this Oriental genus, as well as to key its three currently known species and map their distributions. The tribes Alogolykini and Polydrepanini, as well as the subfamily Alogolykinae are also briefly redefined.

On the identification of the species Griphobilharzia amoena Platt, Blair, Purdie et Melville, 1991, a parasite of crocodiles in Australia

The results of the study of typical specimens of the trematode G. amoena from blood vessels of the crocodile Crocodylus johnstoni in Australia are provided. The data obtained on the morphology of this parasite did not confirm the statement of Platt et al. (1991) that this species belongs to the family Schistosomatidae. Morphological data on G. amoena enable attributing it to the genus Vasotrema of the family Spirorchidae as a new species. In this connection, the monotypical genus Griphobilharzia (justified by Platt et al., 1991) becomes a synonym of the genus Vasotrema, while the subfamily Griphobilharziinae becomes a synonym of the subfamily Hapalotrematinae.     

New species of the genus Cyamops Melander from New Zealand (Diptera, Periscelididae, Stenomicrinae)

Two new species of the genus Cyamops (Diptera: Periscelididae), the first from New Zealand, are described. The two newly described species are: Cyamops alessandrae and Cyamops crosbyi. A key to the genera of the subfamily Stenomicrinae and to the species of Cyamops from the Australasian/Oceanian Region and detailed illustrations of structures of the male terminalia are provided.     

Loxocaudinae: A new subfamily in the ostracod family loxoconchidae

A new Ostracoda subfamily, Loxocaudinae subfam. nov., separated from the subfamily Loxoconchinae of the family Loxoconchidae with five genera (Loxocauda Schornikov, 1969, Glacioloxoconcha Hartmann, 1990, Phlyctocythere Keij, 1958, Pseudoloxoconcha Müller, 1894 and Sarmatina Stancheva, 1984) is described in the paper. The new subfamily differs from Loxoconchinae Sars, 1926 s. str. by the presence of a compact eye, the absence of an eye tubercle, an originally adont hinge with a tendency to formation of an anterior tooth on the left valve and a posterior one on the right valve, a pronounced caudal process and reduction of fossa-mural sculpture. The volume of the genera that are included in the subfamily is determined. A review of 55 various species and forms mentioned in the literature in open nomenclature, whose taxonomic position has not been determined yet is presented. A total of 45 species close to Loxocauda are attributed to the new subfamily, but proper morphological investigations are necessary for their classification. Ten species that were referred earlier to the genera included in Loxocaudinae are excluded from this subfamily. Issues of functional morphology of Loxocaudinae shells and morphological evolution of their sculpture are considered.     

Phylogeny of the North American vaejovid scorpion subfamily Syntropinae Kraepelin, 1905, based on morphology,mitochondrial and nuclear DNA

The first rigorous analysis of the phylogeny of the North American vaejovid scorpion subfamily Syntropinae is presented. The analysis is based on 250 morphological characters and 4221 aligned DNA nucleotides from three mitochondrial and two nuclear gene markers, for 145 terminal taxa, representing 47 species in 11 ingroup genera, and 15 species in eight outgroup genera. The monophyly and composition of Syntropinae and its component genera, as proposed by Soleglad and Fet, are tested. The following taxa are demonstrated to be para‐ or polyphyletic: Smeringurinae; Syntropinae; Vaejovinae; Stahnkeini; Syntropini; Syntropina; Thorelliina; Hoffmannius; Kochius; and Thorellius. The spinose (hooked or toothed) margin of the distal barb of the sclerotized hemi‐mating plug is demonstrated to be a unique, unambiguous synapomorphy for Syntropinae, uniting taxa previously assigned to different subfamilies. Results of the analysis demonstrate a novel phylogenetic relationship for the subfamily, comprising six major clades and 11 genera, justify the establishment of six new genera, and they offer new insights about the systematics and historical biogeography of the subfamily, and the information content of morphological character systems.     

New and little known crickets of the subfamily phalangopsinae (Orthoptera, Gryllidae): 3. Indonesia, the Philippines, and Seychelles

Two new subgenera and eight new species of the subfamily Phalangopsinae are described from Sulawesi, Supiori, Mindoro, Palawan, Sumatra, and Cousin islands. Two former subgenera, Longizacla and Brevizacla, are considered as genera. The new synonymy for a subgenus of the genus Luzonogryllus is established. Diagnostic characters and systematic position of some taxa are discussed.     

Three New Species of Minoninae (Turbellaria, Proseriata, Monocelididae) from the North Sea, with Remarks on the Taxonomy of the Subfamily

Three new species of Minoninae are described and a new genus is proposed for one of them: Minona degadti sp.n., Duplominona septentrionalis sp.n. and Duploperaclistus circocirrus gen. et sp.n. All three species occur in sublittoral sandy habitats in the Southern Bight of the North Sea, but D. circocirrus has also been found at a littoral station. The taxonomy within the subfamily Minoninae is discussed. Seven genera are considered as valid, and they are briefly diagnosed. " Peraclistus ituipus" sensu Westblad (1952) (= Duplominona westbladi Karling, 1966) is included in the new genus as Duploperuclistus westbladi (Karling, 1966) comb.n.     

Ciliate Protozoa in the Rumen of Sassaby Antelope, Damaliscus lunatus lunatus, Including the Description of a New Species and Form

ABSTRACT. Composition of rumen ciliate fauna in five Zambian, sassaby antelopes was determined. Six genera, 18 species, and four forms were identified. One new species and form, belonging to the subfamily Diplodiniinae, were found, then labeled Ostracodinium damaliscus n. sp. and Diplodinium bubalidis f. aspinosum n. f., respectively. Only ophryoscolecid species were present while isotrichids were absent. Twelve of 18 total species are commmonly found in African antelopes. Three of those 12 species, Entodinium fyferi, Enoploplastron garstangi and Opisthotrichum janus , are only found in African antelopes. Percentage composition was low in the genera ml of rumen fluid, and the average number of ciliate species per host was 17.2.

Mendesellinae, a new subfamily of braconid wasps (Hymenoptera, Braconidae) with a review of relationships within the microgastroid assemblage

Abstract. A new subfamily of braconid wasps, the Mendesellinae, is proposed and described. It is represented by two genera and nine species, all newly described: Mendesella gen.n., type species M.amazonica sp.n., M.braziliensls , sp.n., M.magna sp.n., Epsilogaster gen.n., type species E.bicolor sp.n., E.brazMensis sp.n., E.dureno sp.n., E.palenque sp.n., E.tico sp.n. and E.panama sp.n. The phylogenetic relationships among the subfamilies of the 'microgastroid assemblage' of Braconidae are reviewed and analysed, to clarify the status and relationships of the new subfamily.     

Phylogenetic systematics of Pseudolebinthus, a new genus of Eneopterinae crickets (Orthoptera, Grylloidea, Eneopteridae) from south-east Africa

Abstract.  Within a framework of historical analysis of Eneopterinae crickets, the genus Pseudolebinthus Robillard gen.n. and two new species P. africanus Robillard, sp.n. and P. whellani Robillard, sp.n. , endemic from south-east Africa, are described. A cladistic analysis using 198 morphological characters and 47 terminals assessed the phylogenetic position of the new taxa within the subfamily. The resultant topologies support the previously proposed phylogeny for the subfamily and contained tribes. The monophyly of Pseudolebinthus is supported strongly as well as its sister relationship with Xenogryllus within the tribe Xenogryllini. A key to Eneopterinae tribes, Xenogryllini genera and Pseudolebinthus species is given. Taxonomic, evolutionary and acoustic issues raised by the recognition of Pseudolebinthus are discussed.
