Parakaketio longiprostatus gen. et sp.n., a Marine Tubificid (Oligochaeta) from Florida, U.S.A.

Parakaketio longiprostatus sp.n. is described from shallow marine water in S.E. Florida. The male ducts of the new genus Parakaketio resemble those of Kaketio Righi & Kanner, 1979, but do not end as voluminous, eversible pseudopenes, rather as simple tubes opening directly to the exterior through simple pores.     

The marine Tubificidae (Oligochaeta) of the barrier reef ecosystems at Carrie Bow Cay, Belize, and other parts of the Caribbean Sea, with descriptions of twenty-seven new species and revision of Heterodrilus, Thalassodrilides and Smithsonidrilus

Fifty-nine species of Tubifieidae are recorded from Belize on the Caribbean side of Central America. Twenty-five are new to science: Ainudrilus geminus sp.n., Heronidrilus gravidus sp.n., Heterodrilus flexuosus sp.n., H. ranus sp.n., H. modestus sp.n., Coralliodrilus rugosus sp.n., C. randyi sp.n., Phallodrilus compactus sp. n., P. singularis sp.n., P. vicinus sp.n., P. nasutus sp.n., P. bipartitus sp.n., Inanidrilus reginae sp.n., Olavius finitimus sp.n., O. vacuus sp.n., O. (Olavius) pravus sp.n., Bathydrilus vetustus sp.n., B. egenus sp.n., Thalassodrilides bruneti sp.n., Limnodriloides anxius sp.n., L. major sp.n., L. sacculus sp.n., L. adversus sp.n., Smithsonidrilus appositus sp.n., S. involutus sp.n. Phylogenetic analyses indicate that Heterodrilus Pierantoni, 1902, Thalassodrilides Brinkhurst & Baker, 1979, and Marcusaedrilus Righi & Kanner, 1979, are paraphyletic taxa as previously defined. They are therefore revised to include also apomorphic species earlier attributed to separate genera; in so doing, Marcusaedrilus becomes a junior synonym of Smithsonidrilus Brinkhurst, 1966. Smithsonidrilus pauper sp.n. (Peru), and S. multiglandularis sp.n. (Florida and Puerto Rico) are also described, and Limnodriloides claviger Erséus, 1982 is regarded as a synonym of L. pierantonii (Hrabě, 1971).     

Six new species of marine Tubificidae (Oligochaeta) from the continental shelf off Peru

Six species of marine tubifieids are described from the continental shelf off Peru. Two of them are members of the gutless genus Olavius Erséus, 1984 (subfamily Phallodrilinae). Olavius bullatus sp.n. possesses 2 pairs of large penial setae in voluminous copulatory sacs, tiny atria, and spermathecal pores in line with dorsal setae. Olavius crassitunicatus sp.n. is characterized by small atria with thin muscular layer, spermathecae with short ducts, opening dorso-laterally, and lack of penial setae. Four species arc members of the subfamily Limnodriloidinae. Limnodriloides busilicus sp.n. belongs to the appendiculatus-group (sensu Erséus). It is discriminated by somatic setae with subdental ligaments, and its voluminous elongate prostatic pads. Limnodriloides clavellatus sp.n. is distinguished from its congeners by a peculiar bulge in the cavity of each atrial ampulla, and spermatozeugmata imbedded in the walls of the spermathecae. Tectidrilus intermixtus sp.n. is similar to T. bori (Righi & Kanner, 1979); it is distinguished from the latter by having trisetal bundles in segment V or V-VI and by lacking copulatory glands. Marcusaedrilus peruanus sp.n. is characterized by nongranulated atrial ducts and bipartite spermathecae.     

Myoretronectes paranaensis n. gen. et sp., a new freshwater genus of the family Retronectidae (Turbellaria, Catenulida) from the Paraná, Argentina

Myoretronectes paranaensis, gen. et sp. n., from lotic sandy bottoms of the Paraná river, Argentina, is described. The establishment of the new genus is based on the presence of a non-ciliated pharynx, a discrete oesophagus, and a strong muscle system surrounding the distal pharynx. A new emended diagnosis of the family Retronectidae is presented. Myoretronectes paranaensis apparently cohabits with the oligochaete Narapa bonettoi Righi & Varela, 1983 and the copepod Parastenocaris sp.     

Taxonomy and Phylogeny of the Gutless Phallodrilinae (Oligochaeta,Tubificidae), with Descriptions of One New Genus and Twenty-Two New Species*

The gutless members of the subfamily Phallodrilinae are taxonomically revised and generically split off from their gut-bearing relatives. Inanidrilus Erséus, 1979, a much modified definition of which is presented, comprises the species leukodermatus (Giere, 1979) comb.n., speroi sp.n., fijiensis sp.n., bonomii sp.n., carterensis sp.n., gustavsoni sp.n., wasseri sp.n., scalprum sp.n., belizensis sp.n., aduncosetis sp.n., vacivus sp.n., triangulatus sp.n., ernesti sp.n., manae sp.n., falcifer Erséus & Baker, 1982, renaudae sp.n., extrmus (Erséus 1979) comb.n., mexicanus Erséus & Haker, 1982, and bulbosus Erséus, 1979. Olavius sp.n. is established to accommodate the species geniculatus (Erséus, 1981) comb.n., imperfectus sp.n., filithecatus (Erséus. 1981) comb.n. albidus (Jamieson, 1977) comb.n., propinquus sp.n., comorensis (Erséus. 1981) comb.n., cornuatus Davis, 1984, pellucidus sp.n., tenuissimus (Erséus, 1979) macer sp.n., caudatus (Erséus. 1979) comb.n., planus (Erséus, 1979) comb.n., clavatus (Erséus. 1981) comb.n., tantulus sp.n., longissimus (Giere, 1979) comb.n., alius sp.n., avisceralis (Erséus, 1981) comb.n., loisae sp.n., and hanssoni sp.n., Two subgenera are erected for tantulus—longissimus–alius (nominate subgenus Olavius) and avisceralis-loisae-hanssoni (Coralliodriloides subgen.n.), respectively. A tentative phylogeny of the gutless group, which appears monophyletic, is inferred on the basis of a partly computerized Wagner-tree analysis of all 38 species. According to this analysis. According to this analysis, Inanidrilus can be defined by one synapomorphy, more or less sickle-shaped penial setae, whereas Olavius can be discriminated by two such characters, (1) atrium comma-shaped/horizontal rather than erect and (2) copulatory sacs present.     

The cyclopoid copepods of a wet campo marsh in central Brazil

Eight species of cyclopoid copepods were recorded from 1979–1983 in the complex microhabitats of a wet campo (campo úmido) marsh in central Brazil. Ectocyclops herbsti and Paracyclops fimbriatus occurred most often in areas with water covering the soil; Muscocyclops therasiae n. sp. occurred mainly in soils with no surface water; while Metacyclops campestris n. sp. showed no distinct microhabitat preference. Occurrence of the remaining four species was too sporadic to determine microhabitat preference. Paracyclops carectum n. sp., Metacyclops campestris n. sp., Muscocyclops therasiae n. sp., Muscocyclops bidentatus n. sp. and Ponticyclops boscoi n. g. n. sp. are described. A key to the New World species of Metacyclops s. str. is provided.     

Descriptions of new taxa of the Clausiliidae from Turkey (Mollusca: Stylommatophora)

Summary

Several new taxa of the Clausiliidae were described From Turkey: Dobatia multidentifera n. sp., Albinaria monocristata n. sp., Albinaria basalifera n. sp., Roseniella (Chavchetia) n. subgen., Roseniella (Chavchetia) rufina n. sp., Armenica euprepes truncata n. ssp., Armenica multispirata n. sp., Armenica bicarinata grisea n. ssp., Kazancia n. gen., and Kazancia monticola n. sp. Investigations were made of the genital morphology of some species, and the arrangement of the taxa in Nordsieck’s classification (H, NORDSIECK 1979) is discussed.     

Revision of the southern African genus Macroderes Westwood (Coleoptera: Scarabaeidae: Scarabaeinae)

The southern African genus Macroderes Westwood is revised. Six new species, M. amplior n. sp., M. minutus n. sp., M. endroedyi n. sp., M. namakwanus n. sp., M. foveatus n. sp., and M. cornutus n. sp., are described.The neotype of M. bias (Olivier) is designated.Two new synonymies are established: M. pilula Sharp is a junior synonym of M. bias (Olivier), and M. westwoodi Preudhomme de Borre is a junior synonym of M. undulatus Preudhomme de Borre. A key to species and notes on biology and distribution are given.     

New species of Euptyctima (Acari,Oribatida) from New Zealand

Abstract

Oribotritia contortula n. sp., O. contraria n. sp., O. teretis n. sp., Rhysotritia bifurcata n. sp., Microtritia contraria n. sp., M. glabrata n. sp., Hoplophthiracarus bisulcus n. sp., Austrophthiracarus pulchellus n. sp., and Notophthiracarus claviger n. sp. are described from New Zealand.

The genera of Oribotritia Jacot, Rhysotritia Märkel & Meyer, Hoplophthiracarus Jacot, and Austrophthiracarus Balogh & Mahunka are new records for New Zealand.     

Some new species of Haplotaxidae (Oligochaeta) from Guinea and remarks on the history of the family

Three new species of Haplotaxidae collected by Dr. A. Villiers in a cave near Kindia, Guinea, are described. One species belongs to the genus Metataxis Righi, 1985 (M. carnivorus sp. nov.) which is distributed in Western Africa and Eastern America. Another new species is similar to Lycodrilus kraepelini Michaelsen, 1914 incertae sedis: a new genus Villiersia is proposed for both species (V. guanivora sp. nov., V. kraepelini nov. comb.).A third species, of which only immature specimens are available, is tentatively attributed to the genus Haplotaxis: it is remarkable because of its peculiar setae and commissural vessels (H. villiersi sp. nov.).The three species appear to feed on bat guano and, occasionally, on aquatic arthropods. Metataxis, Tiguassu and Villiersia belong to the section of Haplotaxidae endowed with paired sperm sacs and ovisacs.The relations of Haplotaxidae with other families are discussed and it is suggested that the passage from the haplotaxid condition to that of sparganophilids and more advanced lumbriciforms is connected to a change of reproductive strategy and to an enhanced metabolism.     

A new and a rare parasitic copepod from fishes of Kuwait

Summary A new lernaeopodid copepod, Sparidicola papilliferens n.g., n. sp., is described from Acanthopagrus latus (Pisces: Teleostei) taken in Kuwait. This species is designated as a type of its genus, to which is transferred a second species, originally described as Brachiella lithognathae Kensley & Grindley, 1973, renamed Sparidicola lithognathae (Kensley & Grindley 1973) n. comb. A new name, Neobrachiella pillaii nom. nov., is proposed for Brachiella indica Pillai, 1968. The original name is preoccupied by Brachiella indica Tripathi, 1962, which is also transferred to the genus Neobrachiella Kabata, 1979, as N. indica (Tripathi, 1962) n. comb.     

Origin and radiation of rissooidean gastropods (Caenogastropoda) in ancient lakes of Sulawesi

Zielske, S., Glaubrecht, M. & Haase, M. (2010). Origin and radiation of rissooidean gastropods (Caenogastropoda) in ancient lakes of Sulawesi. —Zoologica Scripta, 40, 221–237. We investigated diversity and origin of as well as relationships among rissooidean gastropods from the ancient lakes of Sulawesi. Analyses of morphological, anatomical and genetic data (16S rRNA, COI and 18S rRNA) revealed ten new species: Sulawesidrobia perempuan sp. n., which is probably parthenogenetic, Sulawesidrobia soedjatmokoi sp. n., Sulawesidrobia mahalonaensis sp. n., Sulawesidrobia anceps sp. n., Sulawesidrobia bicolor sp. n., Sulawesidrobia megalodon sp. n., Sulawesidrobia abreui sp. n., Sulawesidrobia datar sp. n., Sulawesidrobia yunusi sp. n. and Sulawesidrobia towutiensis sp. n. In two cases morphological and anatomical differentiation between pairs of species were not paralleled by genetic differentiation suggesting young speciation events and incomplete lineage sorting as a likely explanation. A Bayesian phylogenetic analysis including representatives of most rissooidean families placed Sulawesidrobia Ponder & Haase 2005 among Tateidae and thus indicated an Australasian origin of the genus. Relationships among the Sulawesian species suggested that isolated Lake Poso was colonised only once whereas the lakes of the Malili system experienced repeated colonizations.     

Monogenoidean parasites of the gill lamellae of the sheepshead Archosargus probatocephalus (Walbaum) (Perciformes: Sparidae) from the Indian River Lagoon, Florida, with descriptions of four new species of Euryhaliotrema Kritsky & Boeger, 2002 (Dactylogyridae)

Examination of the gill lamellae of three sheepshead Archosargus probatocephalus (Walbaum) from the Indian River Lagoon in Florida revealed six species of Monogenoidea: Microcotyle archosargi MacCallum, 1913 (Microcotylidae); Neobenedenia sp. (Capsalidae); and four new species of Euryhaliotrema Kritsky & Boeger, 2002 (Dactylogyridae). The prevalence of all helminths was 100%, except for Neobenedenia sp., which was represented by a single immature specimen. The four new species, Euryhaliotrema carbuncularium n. sp., E. dunlapae n. sp., E. amydrum n. sp. and E. spirulum n. sp., are described and with E. carbunculus (Hargis, 1955) Kritsky & Boeger, 2002 apparently constitute a monophyletic clade of Euryhaliotrema spp. that parasitise sparid hosts in the western hemisphere. The Indian River Lagoon in Florida represents a new locality record for M. archosargi, and the sheepshead is apparently a new host record for a member (Neobenedenia sp.) of the Capsalidae.     

The genus Microserangium Miyatake (Coleoptera,?Coccinellidae) from China

The genus Microserangium Chapinfrom China is reviewed. Nine species are recognized, including seven new species: M. erythrinum Wang & Ren, sp. n., M. fuscum Wang & Ren, sp. n., M. glossoides Wang & Ren, sp. n., M. shennongensis Wang & Ren, sp. n., M. semilunatum Wang & Ren, sp. n., M. deltoides Wang & Ren, sp. n., M. dactylicum Wang & Ren, sp. n. Male genitalia of M. hainanensis Miyatake, 1961 are described for the first time. All species are described and illustrated. A key and distribution map to the known species from China are given.     

Revision of the genus Diclidophora Krøyer, 1838 (Monogenea: Diclidophoridae), with the proposal of Macrouridophora n. g.

The present study re-examines the detailed morphology of the type-species, Diclidophora merlangi (Kuhn, in Nordmann, 1832) Krøyer, 1838, and other Diclidophora species parasitic on gadid fishes: D. denticulata (Olsson, 1876) Price, 1943, D. esmarkii (Th. Scott, 1901) Sproston, 1946, D. luscae (van Beneden & Hesse, 1863) Price, 1943, D. minor (Olsson, 1868) Sproston, 1946, D. palmata (Leuckart, 1830) Diesing, 1850, D. phycidis (Parona & Perugia, 1889) Sproston, 1946, D. pollachii (van Beneden & Hesse, 1863) Price, 1943 and the recently described D. micromesisti Suriano & Martorelli, 1984. An amended generic diagnosis of Diclidophora Krøyer, 1838 (synonym Diclidophora Diesing, 1850) is provided, which includes the presence of a prostatic vesicle in the terminal male genitalia and the distal fusion of the median and peripheral sclerites, a₁ and c₁ in the clamp anterior jaw. Macrouridophora n. g. is herein proposed for species previously considered in Diclidophora, which are parasitic on macrourid and morid fishes. The clamp morphology in Macrouridophora n. g. has distinct lamellate extension attachments to peripheral sclerites c₁ and the distal portion of d₁, with no distal fusion between a₁ and c₁ in the anterior jaw. Macrouridophora macruri (Brinkmann, 1942) n. comb. is chosen as the type-species. Nine other species are herein transferred to Macrouridophora n. g.: M. coelorhynchi (Robinson, 1961) n. comb., M. lotella (Machida, 1972) n. comb., M. nezumiae (Munroe, Campbell & Zwerner, 1981) n. comb. and M. tubiformis (Rohde & Williams, 1987) n. comb. are redescribed, based on the re-examination of type or voucher specimens. Macrouridophora attenuata (Mamaev & Zubtschenko, 1979) n. comb., M. caudata (Mamaev & Zubtschenko, 1984) n. comb., M. papilio (Mamaev & Avdeev, 1981) n. comb., M. paracoelorhynchi (Mamaev & Paruchin, 1979) n. comb. and M. physiculi (Mamaev & Avdeev, 1981) n. comb. have adequately described haptoral clamps in the literature. The clamp morphology in Macrouridophora sp. from Lepidorhynchus denticulatus in Australia is also considered. Diclidophora whitsonii Suriano & Martorelli, 1984 is herein transferred to the genus Macruricotyle Mamaev & Ljadov, 1975, as M. whitsonii (Suriano & Martorelli, 1984) n. comb. D. embiotocae Hanson, 1979 is herein considered a species incertae sedis. D. caudospina Khan & Karyakarte, 1983 and D. paddiforma Deo & Karyakarte, 1979 are herein considered species inquirendae. D. aglandulosa Deo, 1977, D. glandulosa Das, 1972, D. minuta Das, 1972 and D. spindale Deo, 1977 are formally dismissed as nomina nuda. The systematic position of Diclidophora Krøyer, 1838 and Macrouridophora n. g. in the subfamily Diclidophorinae Cerfontaine, 1895 (sensu Mamaev, 1976) is discussed.     

Morphological Characterizations of Four Species of Parallelostrombidium (Ciliophora,Oligotrichia), with a Note on the Phylogeny of the Genus

The morphology and phylogeny of four oligotrichid ciliates, Parallelostrombidium paraellipticum sp. n., P. dragescoi sp. n., P. jankowskii (Xu et al. 2009) comb. n., and P. kahli (Xu et al. 2009) comb. n., are described or redescribed based on live observation, protargol stained material, and SSU rRNA gene sequences. The new species P. paraellipticum sp. n. is characterized by its obovoidal cell shape, adoral zone composed of 17–21 collar, 9–11 buccal, and two thigmotactic membranelles, and extrusomes attached in one row along the girdle kinety. The new species P. dragescoi sp. n. is distinguished from its congeners by its obovoidal cell shape and a lack of thigmotactic membranelles. Based on ciliary patterns recognizable in the original slides, Omegastrombidium jankowskii Xu et al. 2009 and O. kahli Xu et al. 2009 should be transferred to the genus Parallelostrombidium Agatha 2004. Phylogenetic analyses based on SSU rRNA gene sequence data demonstrate that all four new sequences cluster with previously described congeners. The genus Parallelostrombidium is separated into two clusters, suggesting its non‐monophyly and probably corresponding to the two subgenera proposed by Agatha and Strüder‐Kypke (2014), as well as their morphological difference (cell dorsoventrally flattened vs. unflattened).     

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.     

New species of sap beetles (Coleoptera: Nitidulidae: Nitidulini) from the Baltic and Bitterfeld ambers

A new genus, Microsoronia, gen. nov., and new species of this genus, M. hoffeinsorum, sp. nov. from the Bitterfeld amber and M. kerneggeri sp. nov., M. nigerrima sp. nov., and M. interfax, sp. nov. from the Baltic amber, are described. The earliest known member of the genus Phenolia, P. (Lasiodites) angustitibialis, sp. nov., is described from the Baltic amber. The systematic position of these two genera, their possible evolution, as well as the possible ecology and bionomics of their members are discussed. It is shown that “Phenolia” incapax Scudder, 1890 should be included in the family Peltidae, rather than Nitidulidae.     

Neotropical Monogenoidea. 50. Oviparous gyrodactylids from loricariid and pimelodid catfishes in Brazil, with the proposal of Phanerothecioides n. g., Onychogyrodactylus n. g. and Aglaiogyrodactylus n. g. (Polyonchoinea: Gyrodactylidea)

The diagnosis of Phanerothecium Kritsky & Thatcher, 1977 is amended, and Phanerothecioides n. g., Onychogyrodactylus n. g. and Aglaiogyrodactylus n. g., all comprised of oviparous gyrodactylids (Monogenoidea: Polyonchoinea), are proposed to accommodate 11 of the 15 species (14 new to science) herein described and/or reported from loricariid and pimelodid catfishes (Teleostei: Siluriformes) in Brazil: Phanerothecium harrisi Kritsky & Boeger, 1991, P. spinatoides n. sp. and P. deiropedeum n. sp. all from Hypostomus spp.; P. spinulatum n. sp. from Hypostomus cf. regani; Phanerothecioides agostinhoi n. g., n. sp. (type-species) from Hypostomus spp. and Pseudoplatystoma fasciatum; Onychogyrodactylus sudis n. g., n. sp. (type-species) and O. hydaticus n. sp. both from Ancistrus multispinus; Aglaiogyrodactylus forficulatus n. g., n. sp. (type-species) from Kronichthys lacerta; A. pedunculatus n. sp. from Hisonotus sp.; A. guttus n. sp. from Pseudotothyris obtusa; A. salebrosus n. sp., A. conei n. sp. and A. ctenistus n. sp. all from Pareiorhaphis parmula; and A. calamus n. sp. and A. forficuloides n. sp. both from Schizolecis guntheri. Phanerothecioides n. g. is characterised by oviparous forms lacking superficial and deep haptoral bars and pregermarial vitelline follicles, and by having a conspicuous testis in adult specimens, a syncytial prostatic gland, a reduced copulatory sac and vitelline ducts in the form of an inverted ‘U’. Onychogyrodactylus n. g. is differentiated from all other oviparous gyrodactylid genera by its members having a spine-like accessory sclerite enclosed in a separate pouch associated with the terminal male genitalia. Species of Aglaiogyrodactylus n. g. possess H-shaped vitelline ducts and a complex accessory piece and sclerotised or non-sclerotised male copulatory organ enclosed within the copulatory sac.
