Revision of the genus Caucasocressa from the eastern Pontic Region (Gastropoda: Hygromiidae)

The genus Caucasocressa is revised. Ten Caucasocressa species are known from north-east Turkey and south-west Georgia. Five new species are described. For every taxon the shell is described and illustrated and the variability of the genitalia (as far as known) is shown. All synonyms are listed. The distribution is summarized and all locality records are listed. The distribution of the species is illustrated on a UTM grid-map.     

The genus Monacha in the Western Caucasus (Gastropoda: Hygromiidae)

Seven Monacha species have been found in the Western Caucasus region. Six of these species are endemic there. They all belong to the subgenera Paratheba and Metatheba. Three species are new to science. M. (Paratheba) claussi, sp. n. and M. (Metatheba) subcarthusiana (Lindholm) are the only Monacha species, in which the right ommatophoral retractor sometimes crosses with the penis. This might be due to an ancestral polymorphism, atavism or a basal position of the two species within Monacha, which would mean that Paratheba is paraphyletic and Metatheba is polyphyletic. Monacha (Monacha) cartusiana (O. F. Muller), the only Monacha sensu stricto species in the Caucasus region, has probably been introduced by man. The shell and the genitalia of every species are described and illustrated. The synonyms and all Caucasian locality records are listed. The distributions of the species are illustrated on UTM-grid maps.     

The genus Lilloiconcha in Colombia (Gastropoda: Charopidae)

The name Lilloiconcha Weyrauch, 1965 Weyrauch, W. K. 1965. Neue und verkannte Endodontiden aus Südamerika.. Archiv für Molluskenkunde, 94: 121–134.  [Google Scholar] is used tentatively for South American charopids with a reduced penis, a barely differentiated epiphallus and multicuspid marginal radular teeth. Trochogyra Weyrauch, 1965 Weyrauch, W. K. 1965. Neue und verkannte Endodontiden aus Südamerika.. Archiv für Molluskenkunde, 94: 121–134.  [Google Scholar] is considered to be a synonym of Lilloiconcha. In addition to the widespread Lilloiconcha gordurasensis (Thiele, 1927 Thiele, J. 1927. Über einige brasilianische Landschnecken.. Abhandlungen der Senckenbergischen Naturforschenden Gesellschaft, 40: 307–329. Plate 26 [Google Scholar]), Lilloiconcha costulata new species and Lilloiconcha laevigata new species are described from the Cordillera Oriental in Colombia. The distribution of Lilloiconcha gordurasensis in South America is summarized.

Lake, which is located in south-west Turkey, are described here. The morphological features of the species are compared with those of the similar species Arrenurus claviger Konike, 1882 and Arrenurus nodosus (Koenike, 1896).     

Cocoon silk chemistry of non-cyclostome Braconidae,with remarks on phylogenetic relationships within the Microgastrinae (Hymenoptera: Braconidae)

Bulk amino acid composition was determined for cocoon silks for 54 species of non-cyclostome braconid wasps collectively representing 14 subfamilies. Little intraspecific variation was encountered either between conspecific individuals of differing origin or between physically different silk layers within a single cocoon. Variation within subfamilies was small except in the Microgastrinae. Most taxa, excluding most microgastrines, had silk of a fairly typical fibroin type with high relative abundances of alanine, serine or glycine (of which either alanine or serine was the most abundant) and usually with moderately low molar concentrations of presumed acidic residues (aspartate/asparagine (As(x)) and glutamate/glutamine (Gl(x))) which ranged from approximately 2% up to nearly 30% (in Helconinae and Blacinae). In the Microgastrinae, members of the genus Microplitis (four species) were similar to the other non-cyclostome subfamilies in having 14.3–26.1 molar % As(x), but the other 10 microgastrine genera investigated produced silks with As(x) the most abundant detected residue comprising 32.4–50.5 molar % while glycine represented less than 10% of residues, indicating an α-helical silk. These data are discussed in the light of some recent independent phylogenetic studies on the Microgastrinae that also suggest a basal position for Microplitis within the subfamily, despite its apparently highly specialized biology.     

The postcranial skeleton of Proterorhinus marmoratus with remarks on the relationships of the genus Proterorhinus (Teleostei: Gobiidae)

The postcranial osteology of the Ponto-Caspian tubenose goby Proterorhinus marmoratus is described and its relevance to the systematic position of Proterorhinus is discussed. Proterorhinus marmoratus differs significantly from the gobioids of the Ponto-Caspian and Atlantic-Mediterranean in the anterior displacement of the origin of the first dorsal fin. The first dorsal-fin pterygiophore of the tubenose goby inserts in the second interneural space between the neural spines of the second and third vertebrae. The first pterygiophore of the other gobioids inserts in the third interneural space between the neural spines of the third and fourth vertebrae. The increased number of precaudal and caudal vertebrae and the dorsal pterygiophore formula starting with 2-12 in Proterorhinus marmoratus are derived character states. This 2-12 starting sequence and a single interneural space anterior to the first dorsal-fin pterygiophore are unique for gobioids and autapomorphies of Proterorhinus. It is proposed that Proterorhinus be placed in the subfamily Gobiinae.     

Revision of the American Pupisoma species (Gastropoda: Pupilloidea)

The American species of Pupisoma Stoliczka (Gastropoda: Pupilloidea) are revised. Five species are recognized. Pupisoma puella Hylton Scott has been synonymized with P. dioscoricola (C. B. Adams). This species occurs from southern USA through the Caribbean and Central America to the Galapagos Islands and to southern Brazil and northern Argentina. Pupisoma galapagorum Pilsbry, P. bailyi Pilsbry, and P. latens Hylton Scott have been synonymized with P. comicolense H. B. Baker. This species is distributed from Mexico to the Galapagos Islands, southern Brazil, and northern Argentina. Pupisoma costulata sp. n. from Andean forests in Colombia is described as new. The range of P. macneilli (Clapp) extends from southern USA through the Caribbean and Central America to southern Brazil and northern Argentina. A neotype has been designated for P. mediamericanum Pilsbry. Pupisoma michoacanense Pilsbry is a synonym of this species. This species occurs from Mexico to Colombia and on Jamaica.     

Ciplakastacus gen. nov., a primitive genus of Leptastacidae (Copepoda,Harpacticoida) from the Mediterranean coast of Turkey

Both sexes of Ciplakastacus mersinensis gen. et sp. nov. (Copepoda, Harpacticoida, Leptastacidae) are described in detail based on intertidal material collected from the Mediterranean coast of Turkey (Mersin Province). Plesiomorphic character states displayed by the antenna and P1–P2 indicate Ciplakastacus diverged before the crown group Leptastacidae diversified. The new genus is placed in a basal clade (currently encompassing Archileptastacus and Meloriastacus) defined by eight synapomorphies: (1) caudal ramus with strongly developed seta I flanked by two elongate spinules; (2) caudal ramus with posteriorly directed spinous outgrowth of outer distal corner; (3) caudal ramus seta III vestigial; (4) P5 exopod and baseoendopod forming single plate in both sexes; (5) P2–P4 exp‐3 with one outer spine; (6) dorsal posterior margin of anal somite bilaterally serrate; (7) rostrum triangular or bell‐shaped, and (8) sexually dimorphic ornamentation on the anal somite. Within this clade Ciplakastacus appears most closely related to Meloriastacus on account of the shared presence of the extremely elongate second antennulary segment, an allobasis on the antenna, the strongly reduced accessory seta on the maxillipedal endopod, the subcylindrical sternal process between the maxillipeds and P1, and paired laterodorsal, posteriorly directed, serrate extensions on the anal somite. Both genera can be distinguished from each other by P5 morphology (both sexes), armature of P4 enp‐2 and abdominal hyaline frill structure. The phylogenetic relationships between the basal taxa of the Leptastacidae are briefly outlined.     

New species of Eustigmaeus Berlese, 1910 (Acari: Stigmaeidae) from Turkey

A new deep-sea benthopelagic chaetognath of the genus Bathyspadella (Chaetognatha) with ecological and molecular phylogenetic remarks

A new chaetognath, Bathyspadella oxydentata, collected from Sagami Bay, central Japan, is described. The new species was collected from deep-sea benthopelagic habitat and is distinguished from the closely related species Bathyspadella edentata Tokioka, 1939 Tokioka, T. 1939. Three new chaetognaths from Japanese waters. Mem Imp Mar Obs., 7: 129–140.  [Google Scholar] by the presence of teeth. The phylogenetic position of the new species was examined by molecular genetic analysis using partial sequences of 18S rRNA and 16S rRNA. Although B. oxydentata shares several morphological features with both Spadellidae and Eukrohnidae, the molecular phylogeny indicates that the new species is closely related to Heterokrohnidae species.     

Some species of Favognathus Luxton, 1973 (Acari: Actinedida: Cryptognathidae) from Turkey
