Ciliate Protozoa in the Rumen of Brazilian Water Buffalo,Bubalus bubalis Linnaeus*

SYNOPSIS Total numbers and distribution of genera, subgenera and species were determined for the ciliate protozoa in rumen contents of 4 Brazilian water buffalo Bubalus bubalis Linnaeus. The fauna of one animal, housed in close proximity to European and zebu-type cattle, differed considerably from that of the remaining animals, which were somewhat isolated on a large ranch. Several of the protozoan species observed in the semi-isolated animals were first described in rumen contents from humped Indian cattle, and their subsequent occurrence in other hosts and geographic locations has been limited or absent. In all, 49 different species of protozoa were found, 8 of which have not been previously described. Three of the new species belong to the genus Entodinium: E. ciculum sp. n., E. spinonucleatum sp. n. and E. triangulum sp. n.: 4 to Diplodinium (Ostracodinium): D. (O.) brazili sp. n., D. (O.) esalqum sp. n., D. (O.) nucleolobum sp. n., and D. (O.) tiete sp. n.; and one to Diplodinium (Eudiplodinium): D. (E.) bubalus sp. n.     

A revision of the Afrotropical genus Dhatrichia (Trichoptera, Hydroptilidae)

Five previously described species of Dhatrichia Mosely, 1948 are recognized: D. inasa Mosely, 1948 from Yemen; D. bipunctata Statzner, 1977 from Zaire; D. lerabae (Gibon, Guenda & Coulibaly, 1994) comb. n. from Burkina Faso and Ghana; and D. cinyra Wells & Andersen, 1995 and D. divergenta Wells & Andersen, 1995 from Tanzania. A sixth species D. feredougoubae Gibon, 1987 from the Ivory Coast and Ghana is transferred to Microptila Ris, 1897 comb. n. In addition, nine new species are described and illustrated as males: D. ankasaensis sp. n., D. botiensis sp. n., D. hunukani sp. n., D. minuta sp. n., D. paraminuta sp. n. and D. wliensis sp. n. from Ghana, D. anderseni sp. n. from Tanzania, and D. madagascarensis sp. n. and D. giboni sp. n. from Madagascar. Females are associated, described and illustrated for all species, except D. inasa and D. giboni. The larvae and pupae of D. ankasaensis, D. hunukani, D. lerabae, D. minuta and D. wliensis are described and illustrated as the first known immatures of the genus. Keys to known larvae, pupae, males and females are provided. A phylogenetic analysis of the genus revealed four species groups. The most plesiomorphous taxa are West African, followed by East African and Malagasian taxa. A sister group relationship between the Eburneo–Ghanean and the Sudanian biogeographical regions is encountered twice. Among several possible sister taxa, the sister group turned out to be Kumanskiella Harris & Flint, 1992 and Microptila Ris, 1897 in part, combined. Implications for generic classification and biogeography are outlined. A morphometric principal component analysis revealed good separation of the sexes by the number and shape of antennal segments, and by eye size. Other measures are strongly dependent on overall size, and show best separation of females between species and species groups. A functional fit between male inferior appendages and secondary sexual characters in female sternite VIII is demonstrated for all species with associated females.     

Three new species of Dactylogyrus Diesing, 1850 (Monogenea: Dactylogyridae) from the gills of the bala sharkminnow Balantiocheilos melanopterus (Cyprinidae) from Thailand

Three new species of Dactylogyrus are described from the gills of the cyprinid fish Balantiocheilos melanopterus (Bleeker) imported from Thailand via the aquarium trade. They are D. coartatus n. sp., D. macrocolpius n. sp. and D. melanopteri n. sp. The double-bar species, D. coartatus n. sp. and D. melanopteri n. sp., are characterised by hooks that are markedly large in relation to the size of the anchors. Clip-like anchors with a sharply recurved, long point are a unique feature of D. coartatus n. sp. The single-bar species, D. macrocolpius n. sp., is characterised by having a copulatory organ composed of a spiral copulum and a medial accessory piece with thorns.     

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.     

New data on the systematics of the palaearctic species of the <Emphasis Type="Italic">Dolichopus signifier</Emphasis> group (Diptera,Dolichopodidae)

Three new species of the genus Dolichopus Latr. (Diptera, Dolichopodidae) are described. All these species are closely related to Dolichopus signifer Haliday, 1832 and form a species-group including this species. Dolichopus taimyricus sp. n. is described from the southern tundra of the Taimyr Peninsula (northern Central Siberia); D. zlobini sp. n. was collected in the Pamirs (Tajikistan) and D. asymmetricus sp. n., in the mountains of Kazakhstan, Tajikistan, and Uzbekistan. A key to all these species of the group is given.     

New light into the hormogastrid riddle: morphological and molecular description of Hormogaster joseantonioi sp. n. (Annelida,Clitellata, Hormogastridae)

The earthworm family Hormogastridae shows a remarkable disjunction in its distribution in the Iberian Peninsula, with the Hormogaster elisae species complex isolated from the rest of the species. Hormogaster joseantonioi sp. n., a new species found in the intermediate area between the main ranges (in Teruel, Aragón), was described following the integrative approach, as it is suitable for earthworms due to their highly homoplasic morphology. The phylogenetic analysis of the molecular markers placed the new species as a sister taxon to H. elisae, thus showing the colonizing lineage of Central Iberian Peninsula could have originated near the H. joseantonioi sp. n. current range. External morphological characters revealed some degree of overlap with previously described species, but internal characters presented configurations/states unknown from other members of the family. These traits make the new species a key piece to understand the evolution of Hormogastridae.     

Diplectanids (Monogenea) on the archerfish Toxotes jaculatrix (Pallas) (Toxotidae) off Peninsular Malaysia

Two new and two previously described species of diplectanid monogeneans (Heteroplectanum flabelliforme n. sp., Diplectanum sumpit n. sp., D. jaculator Mizelle & Kritsky, 1969 and D. toxotes Mizelle & Kritsky, 1969) were collected from archerfish Toxotes jaculatrix off the Island of Langkawi, Kedah and off Perak, Malaysia. The reproductive systems and squamodiscs of D. jaculator and D. toxotes are described for the first time. D. sumpit n. sp. differs from D. toxotes and D. jaculator in a having a small curved copulatory tube with a distinct accessory piece, compared to the long, tubular copulatory tube of D. jaculator and the slender tube of D. toxotes. D. sumpit n. sp. also differs from D. toxotes in having a larger ventral bar and larger squamodiscs. H. flabelliforme n. sp. differs from all known Heteroplectanum species in the shape and size of the squamodiscs, the arrangement of the sclerites in the squamodiscs, the extremely large ventral bar and the short, curved, non-spinous copulatory tube.     

Novel isotrichid ciliates endosymbiotic in Australian macropodid marsupials

Samples of foregut content were collected from 86 macropodid marsupials and examined for the presence of endosymbiotic ciliates. Four host species were examined: Macropus giganteus (eastern grey kangaroo), M. fuliginosus (western grey kangaroo), M. robustus (common wallaroo) and Thylogale billardierii (Tasmanian pademelon). Ciliate morphology was determined by microscopical examination of live and silver-impregnated specimens. Isotrichid ciliates were detected in 51 (59%) of the 86 animals examined. Five new species and one new genus are described. Three of the species belong to the genus Dasytricha Schuberg, 1888: D. dehorityi n. sp. from M. giganteus, D. dogieli n. sp. from M. robustus and D. mundayi n. sp. from T. billardierii. Bitricha n. g. is characterised by the possession of two fields of somatic ciliation, a transverse ventral and a longitudinal dorsal field. B. oblata n. sp. is described from M. giganteus and M. fuliginosus and B. tasmaniensis n. sp. is described from T. billardierii. The occurrence of isotrichid ciliates in both metatherian and eutherian mammals suggests that the family either evolved prior to the divergence of the mammalian lineages or switched hosts from one group to the other following host diversification.     

New species of the genus <Emphasis Type="Italic">Dolichopus</Emphasis> (Diptera,Dolichopodidae) from the mountains of the Altai and Tuva

Two new species from the mountains of Altai and Tuva, Dolichopus fursovi Negrobov et Barkalov sp. n. similar to D. grunini Smirnov and D. selivanovae Negrobov et Barkalov, sp. n. similar to D. reichardti Stackelberg, are 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.     

New and known species of Dactylogyrus Diesing, 1850 (Monogenea,Dactylogyridae) from cyprinid fishes of the River Tigris,Iraq

Four new Dactylogyrus species are described and two redescribed from cyprinids of the River Tigris, Iraq. These are as follows: Dactylogyrus barbioides n. sp. from Barbus grypus; D. orbus n. sp. from Barbus lacerta; D. barbuli n. sp. from Barbus barbulus; D. macrostomi n. sp. from Cyprinion macrostomi; D. pavlovskyi Bychowsky, 1949 from Barbus grypus and Barbus sharpeyi; and D. inutilis Bychowsky, 1949 from Barbus xanthopterus. A phylogenetic and zoogeographical analysis is presented.     

New and known species of Dactylogyrus Diesing, 1850 (Monogenea,Dactylogyridae) from Iranian freshwater cyprinid fishes

Three new Dactylogyrus species, D. rectotrabus n. sp. and D. acinacus n. sp. from Garra rufa plus D. carassobarbi n. sp. from Carassobarbus luteus are described from River Dez (Persian Gulf Basin) of Iran. Three known species, D. haplogonus from Rutilus frisii kutum, D. chalcalburni from Alburnus alburnus and Alburnoides bipunctatus, and D. pavlovskyi from Barbus sharpeyi are recorded from the Rivers Sefid (Caspian Basin), Zayandeh (Central Iran) and Dez (Tigris-Euphrates Basin), respectively. Comments on the monogenean fauna of Iranian freshwater fishes are presented.     

Pipunculidae (Diptera) of the 1934 Swedish Expedition to Burma

Hardy, D. E. (Department of Entomology, University of Hawaii, Honolulu, Hi., USA.) Pipunculidae (Diptera) of the 1934 Swedish expedition to Burma. Zool. Scripta 1(3–4): 121–138, 1972.–The collection of Pipunculidae made in Burma by Rene Malaise contained approximately forty species in five genera and four subgenera and is probably a thorough sampling of the species which occur in the Kambaiti area of N.E. Burma. Eleven new species are being described: Dorylomorpha latifrons sp.n., D. stenozona sp.n., Pipunculus (Cephalops) dolosus sp.n., P. (Cephalops) fimbriatus sp.n., P. (Cephalops) validus sp.n., P. (Cephalosphaera) reduncus sp.n., P. (Cephalosphaera) tingens sp.n., P. (Eudorylas) burmanicus sp.n., P. (Eudorylas) colossus sp.n., P. (Eudorylas) giganteus sp.n., and P. (Eudorylas) malaisei sp.n. Several other species, probably new ones, are indicated but not being described until further specimens can be studied. The majority of the species are new records for Burma.     

New genus and new subgenus of subfamily Doryctinae (Hymenoptera: Braconidae) from the Old World fauna

New genus Doryctoproctus n. gen. (type species D. africanus n. sp.) from South Africa, and new subgenus of the genus Pedinotus Szépligeti (Eopedinotus n. subgen. (type species Pedinotus (Eopedinotus) inopinatus n. sp.) from Philippines are described. The genus Pedinotus is recorded in Old World for the first time.     

Small but not ephemeral: newly discovered species of Aphelinidae and Trichogrammatidae (Insecta: Hymenoptera: Chalcidoidea) from Eocene amber

New species of fossil Aphelinidae and Trichogrammatidae are described from middle Eocene (Lutetian) Baltic amber (41.3–47.8 Ma). A new subfamily, two new genera and three new species of Aphelinidae are described, with comments on their placement: Phtuaria fimbriae gen.n. , sp.n. in Phtuariinae subf.n. , Glaesaphytis interregni gen.n. , sp.n. and Centrodora brevispinae sp.n. These represent the first described true fossil Aphelinidae. Four new species of Trichogrammatidae are described: Mirufens illusionis sp.n. , Palaeogramma eos gen.n. , sp.n. , Pterandrophysalis plasmans sp.n. and Szelenyia terebrae sp.n. , thus expanding our knowledge of fossil Trichogrammatidae beyond the single previously described species. The presence of recognizable extant genera of Aphelinidae and Trichogrammatidae in the Eocene suggests that the morphology of these genera has been relatively invariant despite highly variable conditions during and since the Eocene. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:E9AD60B6‐3D56‐4E74‐AA54‐F7B91F4FDC79 .     

New species of the subfamily Conoderinae (Coleoptera: Curculionidae) in Dominican amber

Eulechriops argyrosoman. sp. (Curculionidae: Conoderinae: Lechropini) and Geratozygops platysoman. sp., Geratozygops stenosoman. sp. and Geratozygops arsinotusn. sp. (Curculionidae: Conoderinae: Zygopini) are described from Dominican amber. The small size, nearly parallel sides of the pronotum and silvery sheen distinguish Eulechriops argyrosoma from extant members of the genus, which have not been recorded from Hispaniola. Size and rostral and pronotal characters separate the three Geratozygops species from the single species (Geratozygops atropos) previously described from Dominican amber.http://www.zoobank.org/urn:lsid:zoobank.org:pub:89BC7F43-6C1A-4A6A-839B-CE94C7F6F140

Report on the Polycystididae (Rhabdocoela, Kalyptorhynchia) from Australia, with the Description of Twelve New Species and Six New Genera

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.
