A synopsis of <Emphasis Type="Italic">Bracon</Emphasis> species of Turkey with description of a new species (Hymenoptera: Braconidae: Braconinae)

Our studies on Bracon F. fauna of Turkey started in 1979 and 107 species have been determined so far belonging to the subgenera Habrobracon Ashmead, Asiabracon Tobias, Rostrobracon Tobias, Bracon Fahringer, Cyanopterobracon Tobias, Glabrobracon Fahringer and Lucobracon Fahringer. Thirteen new Bracon species were published from Turkey. With this present study Bracon (Lucobracon) achterbergi Beyarslan sp. n. is described and its diagnostic characters are illustrated. The distribution of Bracon species are discussed according to the Euxin, Subeuxin, Mediterranean, Xeroeuxin, Iran Steppe, Anatolia Steppe, Central Anatolia Steppe and Mesopotamian Steppe phytogeographical provinces of Turkey.     

Two newVeronica species (Scrophulariaceae) of Turkey and Iraq

Veronica davisii M. A.Fischer, sp. n., limited to the mountains of Kurdistan (S. E. Turkey and N. Iraq), is related to the Turkish-CaucasianV. gentianoides Vahl.—V. montbretii M. A.Fischer, sp. n., a local endemic of Erzincan prov. (E. Anatolia), shows affinities to the CaucasianV. liwanensis C. Koch and to the Turkish endemicV. oltensis Woron. & Schelk. from Erzurum province.     

<Emphasis Type="Italic">Platycephala isinensis</Emphasis> sp. n. (Diptera: Chloropidae) from Iran

A new species, Platycephala isinensis sp. n. (Diptera: Chloropidae) is described from Iran and main differential characters are illustrated.     

Eight new Tricoma species (Nematoda,Desmoscolecidae) from a deep-sea transect off Calvi (Corsica,Mediterranean)

Eight new species of the genus Tricoma are described from the Mediterranean: Tricoma (Tricoma) apophysis sp.n., Tricoma (T.) latispicula sp.n., Tricoma (T.) corsicana sp.n., Tricoma (T.) pygmaea sp.n., Tricoma (T.) vincxae sp.n., Tricoma (T.) duopapillata sp.n., Tricoma (T.) setosa sp.n. and Tricoma (Quadricoma) tripapillata sp.n.. All are noteworthy for being small.     

Stylosanthes sp. aff.S. scabra: a putative diploid progenitor ofStylosanthes scabra (Fabaceae)

Stylosanthes sp. aff.S. scabra is an undescribed taxon showing affinities with the allotetraploid speciesS. scabra, but distinct in a number of attibutes. Several collections show potential as forage for clay soils in northern Australia. Twelve accessions have been analysed using STS (sequence-tagged-sites) as genetic markers, and they all displayed STS phenotypes of typical diploid species. Taking into account their morphological similarities, the STS analysis provides strong evidence thatStylosanthes sp. aff.S. scabra might be a diploid progenitor of the allotetraploidS. scabra. This speculation was supported by cytological examinations. Somatic chromosome numbers of two of these accessions were counted and both were found to be diploid (2n = 20). The level of polymorphism among the 12Stylosanthes sp. aff.S. scabra accessions, estimated using randomly amplified polymorphic DNA (RAPD) as markers, was 7.8%, and the dissimilarity value betweenStylosanthes sp. aff.S. scabra andS. viscosa (the other putative progenitor ofS. scabra) was 89%.     

Three new species of ants (genus <Emphasis Type="Italic">Aphaenogaster</Emphasis>, Hymenoptera: Formicidae) from Turkey

Three new species of the ant genus Aphaenogaster (A. aktaci sp. n., A. maculifrons sp. n., A. radchenkoi sp. n.) are described from Turkey and their taxonomic positions are discussed. Aphaenogaster aktaci sp. n. belongs to the obsidiana group, A. maculifrons sp. n. to subterranea group and A. radchenkoi sp. n. to pallida group of the Attomyrma subgenus. Key characteristics for identification of the species and data on their ecology are given.     

<Emphasis Type="Italic">Neobisium babinzub</Emphasis> sp. n. and <Emphasis Type="Italic">Neobisium tarae</Emphasis> sp. n. (Neobisiidae,Pseudoscorpiones) from the central Balkan Peninsula (Serbia)

Two new pseudoscorpion species, Neobisium babinzub sp. n., and N. tarae sp. n. (Neobisiidae, Pseudoscorpiones), were collected in soil and leaf-litter on Mt. Stara Planina and Mt. Tara, Serbia, diagnosed and thoroughly illustrated. The main morphological characteristics of the two taxa clearly demonstrate their adaptation to life in soil.     

Rotifera from north and northeast Anatolia (Turkey)

Samples from 21 freshwater sites in Turkey yielded 91 different species of Rotifera, 42 of which are new to the Turkish fauna. Lepadella costatoides n. sp. is described and L. costata Wulfert is redescribed. L. christineae Koste is synonymised with L. quinquecostata (Lucks). Remarks on the intraspecific variability of some species of Lecane are given. L. pomiformis Edmondson is added to the synonymy of L. pyriformis (Daday). The synonymy of the latter with L. paraclosterocerca Pennak is confirmed.     

<Emphasis Type="Italic">Walckenaeria aksoyi</Emphasis> sp. n. (Araneae: Linyphiidae) from Turkey

Walckenaeria aksoyi sp. n. (Araneae: Linyphiidae) is described based on males from Marmaris Province in Turkey.     

A new species of Bracon (Hymenoptera: Braconidae) parasitic on alien sweetpotato weevils in the south-west islands of Japan

A new species of braconid, Bracon yasudai Maeto et Uesato sp. nov., is described here from the south‐west islands of Japan. It is a solitary idiobiont ectoparasitoid of the larvae of the West Indian sweetpotato weevil, Euscepes postfasciatus (Curculionidae), and the sweetpotato weevil, Cylas formicarius (Brentidae), both feeding on Ipomoea batatas (L.) (Convolvulaceae). The percentage parasitism of the braconid on E. postfasciatus in the vines of I. batatas was 19.9–40.7% in the field. Bracon cylasovorus (Rohwer) reared from C. formicarius in the Philippines is also described.     

Nematodes from the Strait of Magellan and the Beagle Channel (Chile): the genera Cervonema and Laimella (Comesomatidae: Nematoda)

Five species of Cervonema and four species of Laimella are described from the Strait of Magellan and the Beagle Channel, Chile, six species of which are new to science. Cervonema chilensisn. sp. and Cervonema hermanin. sp. are separated from other known species of Cervonema by a short cervical region (less than one head diameter from the front end to the anterior border of the amphids). Cervonema chilensisn. sp. is characterised by a tail length of 5 anal diameters with posterior half filiform; Cervonema hermani n. sp. is characterised by a tail length of 6–9 anal diameter and posterior part (75%) cylindrical. Cervonema shiaen. sp. is characterised by the cephalic seta 4 m long, amphids 9–10 m in diameter; spicules 16 m long and 0.8–0.9 abd; tail 4.7–5.4 anal diameter and 50% posterior part filiform; 4–5 minute precloacal supplements. Laimella subterminatan. sp. is characterised by the subterminal position of the buccal cavity which separates it from the other species of the genus. Laimella annaen. sp. is characterised by the head diameter 9–11 m, cephalic setae and external labial setae 9 + 5 m long, respectively, amphids 7 m in diameter; spicules 28–30 m long; tail 14–17 anal diameter and posterior part (75%) filiform; 5 precloacal supplements. Laimella sandraen. sp. is very close to Laimella annaen.sp. in having similar cephalic sensilla, amphids and spicules. Laimella sandraen. sp., however, can be separated from L.annaen. sp. by the shape of head and the structure of sperm cells, the total body length and the cylindrical part of tail. Cervonema papillatum Jensen, 1988, C. tenuicauda (Stekhoven, 1950) and L. longicauda Cobb, 1920 are found in this area as well. The key of all known species of Cervonemaand Laimellais presented.     

Beetles with ‘trochantelli’: phylogeny of Cephenniini (Coleoptera: Staphylinidae: Scydmaeninae) focussing on Neotropical genera

Neotropical genera of Cephenniini characterized by an additional leg ‘segment’ (‘trochantellus’) are revised, and the following new taxa are described: Shyri gen.n. , Shyri pichincha sp.n. (type species of Shyri) (Ecuador), Shyri perversus sp.n. (Ecuador), Shyri quitu sp.n. (Ecuador), Shyri microphthalmus sp.n. (Ecuador), Monstrophennium gen.n. (type species: Cephennium spinicolle Schaufuss), Furcodes gen.n. , Furcodes apicalis sp.n. (type species of Furcodes) (Mexico), Furcodes tutule sp.n. (Honduras), Paracephennium pumilio sp.n. (Costa Rica), Pseudocephennium iwokramanum sp.n. (Guyana), Pseudocephennium trilineatum sp.n. (Guyana), Pseudocephennium araguanum sp.n. (Venezuela), Pseudocephennium maximum sp.n. (Venezuela), Pseudocephennium peruvianum sp.n. (Peru), Pseudocephennium cochabambanum sp.n. (Bolivia), Pseudocephennium saramaccanum sp.n. (Suriname) and Pseudocephennium brokopondonum sp.n. (Suriname). Pseudocephennium spinicolle (Schaufuss) is transferred to Monstrophennium. Cladistic analysis of characters from adult morphology of all genera of Cephenniini and a large outgroup sample from Cyrtoscydmini, Eutheiini, Scydmaenini, Clidicini and Mastigini strongly supported the monophyly of Cephenniini. However, only the Cephennomicrus group comprising nine genera was strongly supported as a monophyletic clade, while only weak support was found for the previously suggested Cephennodes group and Cephennium group. Two alternative hypotheses concerning the phylogeny of Cephenniini are put forward and discussed: (i) the Cephennium group is sister to all remaining Cephenniini; or (ii) the Cephennomicrus group is sister to all remaining Cephenniini. The Neotropical genera with ‘trochantellus’ form a well‐supported clade derived from the ancestral lineage of the Cephennodes group.     

Two new endemic species of the genus <Emphasis Type="Italic">Omphreus</Emphasis> (Carabidae: Coleoptera) from Montenegro

Two new species, viz. Omphreus (Omphreus) prekornicensis sp. n. (from Medjedje Peak, Mt. Prekornica, C Montenegro) and Omphreus (Omphreus) bjelasicensis sp. n. (from Biogradska Gora National Park, Mt. Bjelasica, E Montenegro), are described and diagnosed. Male and female genitalia and other taxonomically important characteristics are illustrated. The new species are clearly distinct from their closest congeners and represent endemic relicts inhabiting limited regions of the Dinaric mountain system in Montenegro.     

Cardicola aurata sp. n. (Digenea: Sanguinicolidae) from Mediterranean Sparus aurata L. (Teleostei: Sparidae) and its unexpected phylogenetic relationship with Paradeontacylix McIntosh, 1934

A new sanguinicolid trematode, Cardicola aurata sp. n., is described from gilthead seabream Sparus aurata L., from off the Spanish Mediterranean coast. The morphology of C. aurata sp. n. generally agrees with the diagnosis of the genus, however, in contrast to all other reported Cardicola spp. the male pore is located sub-medially at the posterior end of the body instead of sinistrally before the posterior end of the body. Based on a comparison of the morphology as well as partial 28S and ITS2 rDNA sequence data from the present species with that from closely related species, it was decided to emend the diagnosis of Cardicola rather than create a new genus, as the aberrant position of the male pore is likely to be an autapomorphy. The phylogenetic analyses revealed a close relationship between Cardicola and Paradeontacylix, two genera with considerable morphological differences; C. aurata sp. n. occupies a position intermediate to these genera. Thus, a morphological comparison of Cardicola, Paradeontacylix and Braya, a genus which is morphologically similar to Cardicola but clusters basal to the Cardicola/Paradeontacylix clade, was conducted. The results of this comparison showed that despite large differences with regard to body shape, the organisation of the internal organs is very similar in species of Cardicola and Paradeontacylix. The synopsis of morphological data and molecular phylogeny allows for interpretations regarding the importance of different morphological features for the phylogenetic inference of the Sanguinicolidae.     

The genus Pnyxiopalpus gen.n. (Diptera: Sciaridae)

Pnyxiopalpus gen.n. (type-species P. raptor sp.n.), Oriental in distribution, includes the following species: P. acanthipes sp.n. (Malay Peninsula), P. aculeatus sp.n. (Borneo), P. adebratti sp.n. (Borneo), P. aphrodite sp.n. (Sumatra), P. dentaneus sp.n. (Sulawesi), P. fossor sp.n. (Borneo), P. fuscinellus sp.n. (Borneo), P. hamatus sp.n. (Borneo), P. latifalx sp.n. (Borneo), P. macrocellus sp.n. (Malay Peninsula), P. microdon sp.n. (Sumatra), P. nepenthophilus sp.n. (Malay Peninsula), P. noona sp.n. (Palawan), P. raptor sp.n. (Borneo), P. reticulatus sp.n. (Malay Peninsula) and P. simplex sp.n. (Borneo). Males and females are keyed and described. Pnyxiopalpus has a number of characters previously unknown in Sciaridae. In contrast to other Sciaridae, interspecific morphological variation is greater for the females compared to the males. Based on a parsimony analysis of sixty-four morphological characters, Pnyxiopalpus is monophyletic, and its sister group appears to be Spathobdella Frey + {[Peyerimhoffia Kieffer + (Faratsiho Paulian + Pnyxia Johannsen)] + [Hyperlasion Schmitz + (Hermapterosciara Mohrig & Mamaev + Parapnyxia Mohrig & Mamaev)]}. According to the most parsimonious solution, the monophyly of Hyperlasion, Lycoriella Frey and Plastosciara Berg in their current sense is questioned. Aptery and one-segmented maxillary palp, usually regarded as important in sciarid classification, show a lot of homoplasy.     

Feather mites (Astigmata: Psoroptidia) parasitising the rock ptarmigan <Emphasis Type="Italic">Lagopus muta</Emphasis> (Montin) (Aves: Galliformes) in Iceland

Four new species of feather mites are described from the Icelandic rock ptarmigan Lagopus muta islandorum (Faber) in Iceland. These are Metamicrolichus islandicus n. sp., Myialges borealis n. sp. (Epidermoptidae), Strelkoviacarus holoaspis n. sp. (Analgidae) and Tetraolichus lagopi n. sp. (Pterolichidae). This is the first report on feather mites associated with the Icelandic rock ptarmigan. Brief comments on the systematics and biology of corresponding feather mite genera are given. For two species, originally described in Pterolichus Robin, 1868 (Pterolichidae), new combinations are proposed, i.e. Tetraolichus gaudi (Černy, 1971) n. comb. and T. microdiscus (Trouessart, 1887) n. comb.     

Two new species of <Emphasis Type="Italic">Zercon</Emphasis> (Acari: Zerconidae) from Turkey

Two new species of zerconid mites, Zercon uludagicus sp. n. and Z. huseyini sp. n., from Turkey are described and illustrated. The similarities and differences between the species are discussed. The lists of the taxonomic diagnostic key to adults of Zercon species known from Turkey are also given.     

Two new nearctic species of small orthocladiinae (Diptera: Chironomidae) with notes on ecology

Two new species of chironomid midges (Rheosmittia arcuata n.sp. and Mesocricotopus loticus n.sp.) are recognized. They may easily be missed in collections due to their small size, and difficulty in collecting from the larval microhabitat (sand substrates for R. arcuata n.sp., low order streams with depositional substrates including gravel, sand, and silt for M. loticus n.sp.). Some morphological features are given to distinguish the new species from similar congeneric forms. The distribution and some ecological information for each species are also briefly discussed.
