Tanganyikacypridopsis gen.n. (Crustacea, Ostracoda) from Lake Tanganyika

A new genus of freshwater ostracods, Tanganyikacypridopsis gen.n., is established to include the species Potamocypris depressa Kiss, 1959, Cypridopsis calcarata Rome, 1962 and Cypridopsis anomala Rome, 1962, all from Lake Tanganyika. The genus is related to Sarscypridopsis McKenzie, 1977 and Plesiocypridopsis (Rome, 1965), mainly because of its hemipenis anatomy, and is believed to be endemic to Lake Tanganyika.     

Palerasnitsynus gen. n. (Trichoptera, Psychomyiidae) from Burmese amber

Palerasnitsynus ohlhoffigen. et sp. n. is described fromBurmese amber of late Albian (Lower Cretaceous) age. This is the first record of the family Psychomyiidae from Burmese amber, and the earliest fossil record of the family. The genus Palerasnitsynusgen. n. differs from all other known psychomyiid genera by the absence of fork III in the forewings.

Pteromalus pini Hartig (1838): Specie tipo diBeierina gen. nov. (Hym., Chalcidoidea)

Résumé Pteromalus pini Hartig (1838) est l'espèce type du nouveau genreBeierina, que nous venons de décrire. Elle a été élevée à l'origine deApanteles liparidis Bouché (A. nemorum Hartig) et redécrite ensuite sous le nom deSchizonotus pailloti Ferrière & Faure (1925), parasite deApanteles glomeratus L. Le nouveau genreBeierina se rapproche beaucoup du genreKaleva Graham (1957) par la forme particulière du propodeum et l'aspect général du corps.      

Polkepsilonema mombasae gen. et sp.n. andPternepsilonema servaesae gen. et sp.n. (Nematoda,Epsilonematidae) from East African coasts

Two new genera and species from Kenyan tidal areas,Polkepsilonema mombasae gen. et sp.n. andPternepsilonema servaesae gen. et sp.n., are described. Both are characterized by the presence of at least fourteen subcephalic setae and by thick thorns on the ventral body region of males. In the first genus, eight to ten subcephalic setae are situated anterior to the amphid, and the ambulatory setae are bisinuous. In the second, the subcephalic setae are situated at the posterior edge of the rostrum, and the ambulatory setae are straight.A key to the 13 genera of the Epsilonematidae is presented.Abbreviations a body length divided by maximum body diameter - abd body diameter at level of anus - amph % diameter of amphid as a percent of head diameter - Asl length of anteriormost ambulatory seta of external subventral row - b body length divided by pharyngeal length - c body length divided by tail length - cs length of cephalic setae - dcs distance from rostrum edge to cephalic setae - gub length of gubernaculum - L body length - lct length of copulatory thorns - lpt length of precloacal thorns - mbd maximum body diameter of posterior body region - (mdb) minimum body diameter - mbd/(mbd) maximum body diameter divided by minimum body diameter - mbd ph body diameter at level of pharyngeal bulb - N number of body rings - ph length of pharynx - spic length of spicule measured along the arc - SSph length of subdorsal somatic setae in pharyngeal region - t tail length - tmr length of nonannulated tail region - V position of vulva as a percentage of total body length from anterior     

Pararalichus gen.n. (Acarina, Pterolichidae) from New World parrots (Aves, Psittacidae)

Pararalichus gen.n. (Pterolichidae, Pterolichinae) is described; two species groups, from species of Brotogeris Vigors and Touit Gray, respectively, include two named and ten new species. From Brotogeris : the type species Pararalichus dilatatus (Favette & Trouessart) stat.n., comb.n. [= Protolichus ( Mesolichus ) hemiphyllus dilatatus ] from Brotogeris jugularis (Müller), Brazil, Guatemala, Panama; P. chrysopteri sp.n. from B. chrysopterus (L.). Guyana, Surinam; P. cyanopterae sp.n. from B. cyanoptera (Pelzeln), Bolivia, Peru; P. pyrrhopteri sp.n. from B. Pyrrhopterus (Latham), Ecuador, Peru; P. sanctithomae sp.n. from B. sanctithomae (Müller), Bolivia, Peru; P. tiricae sp.n. from B. tirica (Gmelin), Brazil; P. versicolori sp.n. from B. versicolorus (Müller), Brazil, Peru. From Touit: P. hemiphyllus (Mégnin & Trouessart) comb.n. [ =Pterolichus (P.) hemiphyllus ] from Touit batavica (Boddaert), Surinam, Trinidad; P. dilectissimae sp.n. thrn T. dilectissima (Sclater & Salvin), Colmbia, Costa Rica; P. huetii sp.n. from T. huetii (Temminck), Brazil, Guyana, Peru; P. parpuratae sp.n. from T. purpurata (Gmelin), Brazil, Guyana, Surinam; P. surdae sp.n. from T. surda (Kuhl), Brazil. All hosts are Central and South American parrots. Mesolichus Trouessart, 1899 is recognized as a monotypical genus.     

Rhizochrysidopsis vorax,n. gen., n. sp.

Zusammenfassung Die Art ist durch eine bedeutende Variation der Zellgröße, damit auch des Chromatophors und des Kerns ausgezeichnet. Mit steigender Zellgröße nimmt die Zahl der kontraktilen Vakuolen von zwei auf mindestens acht zu. — Unter Umständen erfolgt exzessive animalische Ernährung; es werden auch im Vergleich zum Zellkörper sehr große Algenzellen aufgenommen und verdaut.     

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.     

Tadaridanema delicatus (Schwartz, 1927) n. gen., n. comb. (Trichostrongylina: Molineidae) parasite of Molossidae bats

On the basis of the revision of the type material of Anoplostrongylus delicatus Schwartz, 1927, and new specimens collected from Tadarida brasiliensis mexicana (Saussure, 1860) in 4 arid localities from Mexico, we describe a new genus (Tadaridanema n. gen.), to which A. delicatus is transferred (as Tadaridanema delicatus (Schwartz, 1927) n. gen., n. comb.). This new genus differs from all other genera included in Anoplostrongylinae by having ray 2 larger than ray 3. In addition, T. delicatus can be differentiated from the type species of Anoplostrongylus (Anoplostrongylus paradoxus (Travassos, 1918)) because it possess vestibular branches equal in length, cephalic inflation divided into 2 regions, and synlophe with many small ridges at the midbody level, whereas in T. delicatus, vestibular branches are equal in size, cephalic inflation is simple in structure, and the synlophe has only 2 well-developed dorsal cuticular ridges.     

Taxonomic notes on the Belytinae,with a new species of Pantoclis Förster (Hym., Proctotrupoidea,Diapriidae)

An account is given of a new species of Pantoclis. Paroxylabis laticeps Hellén and the male of Aclista janssoni Nixon, are also described. The three species are from Great Britain.     

Leptepsilonema gen. n. (Nematoda, Epsilonematidae) from Chile and the Caribbean Sea

The new genus Leptepsilonema is erected. L. procerum sp.n from intertidal sandy beaches of the Caribbean sea and L. macrum sp.n. and L. exile sp.n. from Chile are described. Postembryonal development of L. procerum , covering the juvenile stages II-IV, is presented. Some ecological data are added.     

Tervidmonea n.gen. (Bryozoa,Cyclostomata) aus dem Paläogen Mitteleuropas

The new genusTervidmonea (type-species:T. daniensis n.gen. n.sp., ? Fam. Terviidae) is described from the Baltic Danian, from Danian ‘Geschiebe’ (glacial erratic drift material) of Northern Germany, from the Upper Maastrichtian of the Maastricht region, and from the Palaeogene ‘Nummuliten-Mergel’ of Bavaria. The zoarium is erect (‘ldmoneiform’), with alternating uniserial fascicles on the frontal side, as inExidmonea David et al. The dorsal face lacks kenozooids and bears a prominent globular ovicell (gynozooid), by which it differs from the genusTervia Jullien 1882. Certain taxa from the Eocene of the U.S.A. referred toTervia by Canu & Bassler (1920) are considered as congeneric withTervidmonea: T. tumida Smitt,T. globulifera Canu & Bassler, andT. pyrifera Canu & Bassler. However, the identity with the RecentTervia tumida from the Arctic realm remains doubtful and so does the present-day occurrence ofTervidmonea.
