Paronchocerca struthionus n.sp. (Onchocercidae: Splendidofilariinae) from the lungs of Struthio camelus L. (Struthionidae) from West Africa has a long, sacculate glandular oesophagus similar to that of Paronchocerca limboonkengi (Hoeppli and Hsü, 1929) n.comb. (= Lemdana limboonkengi), P. bambusicolae, P. tonkinensis, and P. sonini. It can be distinguished by delicate annular cuticular thickenings and, in the male, a preanal hypodermal swelling, three pairs of circumanal papillae, and the length of the right spicule in relation to the length of the tail. Also, lateral, postanal papillae are absent, although inconspicuous subterminal papillae are present. Paronchocerca ciconiarum Peters, 1936, the type species, is redescribed on the basis of material from the pulmonary arteries of Leptoptilus crumeniferus (Lesson) (Ciconiidae) from Uganda. Seventeen valid species are recognized in the genus. Paronchocerca sanguinisardeae, P. choprai, and P. badamii are regarded as species inquirendae and P. alii, as a species incertae sedis. Among larger avian filarioid genera, Paronchocerca appears unique in that each species seems restricted to a single family of birds. Paronchocerca may have become established in early Ornithurae and subsequently persisted in some of the "primitive" birds, as well as having transferred to "modern" groups which now occupy the aquatic adaptive zone originally occupied by the earliest Ornithurae. Paronchocerca apparently has been largely unsuccessful in transferring to other modern groups.

Species Inquirendae

Species of the genus Sadocus Sørensen, 1886 are conspicuous gonyleptids that occur in Chile and Argentina. Here, the genus is revised for the first time and the cladistic analysis based on morphological characters does not corroborate its monophyly unless a phylogenetically unrelated species is excluded (explained further on). A new classification is proposed for the seven species left in the genus and considered valid, of the 13 nominal species previously recognized. Two out of the seven valid species are considered as species inquirendae: Sadocus allermayeri (Mello-Leitão, 1945) [= Carampangue allermayeri Mello-Leitão, 1945] and Sadocus nigronotatus (Mello-Leitão, 1943) [= Carampangue nigronotatum Mello-Leitão, 1943]. The following synonymies are proposed: Sadocus bicornis (Gervais, 1849) [original combination = Gonyleptes bicornis Gervais, 1849] is a junior synonym of Sadocus asperatus (Gervais, 1847) [= Gonyleptes asperatus Gervais, 1847]; Sadocus conspicillatus Roewer, 1913, Sadocus exceptionalis (Mello-Leitão, 1946) [= Araucanoleptes exceptionalis Mello-Leitão, 1946] and Sadocus guttatus Sørensen, 1902 are junior synonyms of the valid name Sadocus polyacanthus (Gervais, 1847) [= Gonyleptes polyacanthus Gervais, 1847]; and Sadocus calcar (Roewer, 1913) [= Lycomedes calcar Roewer, 1913] is a junior synonym of the valid name Gonyleptes horridus Kirby, 1819. Sadocus brasiliensis Soares & Soares, 1949 is not congeneric with Argentinean/Chilean species of the genus according to the cladistic analysis and is here synonymized with Discocyrtus catharinensis (Mello-Leitão, 1923 [= Sadocus catharinensis Mello-Leitão, 1923]).

AbstractMaterial of the nematode previously known as Heterocephalobus elongatus (and the type of the genus) was collected in four localities from the southern Iberian Peninsula and is described and illustrated. The first SEM study of the species is presented. The species is transferred to the genus Pseudacrobeles on the basis that the lateral field fades out near the phasmid. Within this genus it is classified under the subgenus Pseudacrobeles as the lip region has a triradiate symmetry. The combination Pseudacrobeles (Pseudacrobeles) elongatus (de Man, 1880) comb. n. is proposed. As a result of synonymising the type of Heterocephalobus, the genus itself becomes a junior synonym and is herein placed under the genus Pseudacrobeles, subgenus Pseudacrobeles. The species formerly listed under Heterocephalobus are returned to their original combination and listed as species incertae sedis or species inquirendae.

The ciliate genus Zosterodasys was established with Z. agamalievi as the type species by Deroux (1978). Zosterodasys ischaracterized by (i) an obovoidal to ellipsoidal body which is not differentiated into a rostrum anteriorly; (ii) a conspicuouscyrtos, i.e., an obconical cytopharyngeal apparatus; and (iii) a special thickly ciliated structure, the so-called synhymenium,extending obliquely from the left to the right dorsal cell surface across the ventral side and thus interrupting all ventral ciliaryrows and some dorsal ones. Altogether 31 nominal species were originally described or subsequently combined withZosterodasys. However, we recognize only nine of them as reliable Zosterodasys species, eleven represent nomenclaturalsynonyms, one is a junior primary homonym, five are classified as species inquirendae, and five belong to other genera. Weprovide the following data for each reliable Zosterodasys species: author, date, and journal page of the original description; listof synonyms; diagnosis; type locality; type material; etymology; and remarks. Based on the morphologic and morphometriccharacters, we prepared an illustrated taxonomic key, containing all Zosterodasys species considered identifiable in this revision. Further, we discuss characters that have been used in the morphological taxonomy of the genus Zosterodasys.

Omalaspis Giraud, 1860, is a genus of Aspicerinae (Hymenoptera: Cynipoidea: Figitidae) with a Holarctic distribution. The diagnostic characters that differentiate Omalaspis from morphologically similar genera are described. From the thirteen known species of Omalaspis only O. cavroi (Hedicke, 1914), O. latreillii (Hartig, 1840), O. norica Giraud, 1860 and O. orientalis Belizin, 1968 are valid species. All these species are redescribed. Omalaspis nigra (Hartig, 1840) and O. abnormis (Kieffer, 1901) are synonymized with O. norica, and O. ruficornis Thomson, 1877 is synonymized with O. latreilli. Omalaspis laevis Hedicke, 1914 belongs to Xyalaspis, O. davydovi Belizin, 1927 is considered as ‘incertae sedis’ and O. carinata (Kieffer 1901) ‘species dubia’. Three species are considered as species inquirenda: Omalaspis femoralis Ionescu, 1963 (which belongs to Diapriidae), O. convexa Kierych, 1985 and O. sulcata (Kieffer, 1901). Six new species are described: O. asiatica Ros-Farré & Pujade-Villar n. sp., O. brandaoi Pujade-Villar & Ros-Farré n. sp., O. curvilineata Ros-Farré & Pujade-Villar n. sp., O. gibsoni Ros-Farré & Pujade-Villar n. sp., O. niponica Ros-Farré & Pujade-Villar n. sp. and O. villemantae Pujade-Villar & Ros-Farré n. sp. The diagnostic characters of all species are illustrated and a key to differentiate them is given. A new character is defined here exclusive to Omalaspis within the Aspicerinae, the supratorular impression.

Three new nematode species were found in the Angola Basin (south-east Atlantic Ocean) at depths of about 5500 m. Paracyatholaimus diva sp. nov. (Cyatholaimidae) is characterised by outer labial and cephalic setae of about 3–5 μm, multispiral amphidial fovea with six turns in males and four turns in females situated at the level of the dorsal tooth, buccal cavity armoured with only one prominent dorsal tooth, tail consisting of anterior conical and posterior slender cylindrical half portions, and six preanal midventral setose supplementary organs. Paracyatholaimus diva sp. nov. is most similar to Paracyatholaimus rotundus Gerlach, 1964 but differs by slightly longer body (936–1176 μm versus 705 μm), tail shape (with clearly narrowed posterior half versus conical), six versus four supplementary organs of different shape. The genus Paracyatholaimus Micoletzky, 1923 is briefly reviewed. The genus now includes twenty-four valid species. Five species are considered as species inquirendae, mainly because of inadequate type material lacking adult stages and/or incomplete descriptions. A pictorial guide for identification of the valid species of Paracyatholaimus is provided. Pomponema proximamphidum sp. nov. shares subapical position of the amphidial fovea and distinct lateral differentiation of the somatic cuticle with five Pomponema species: P. concinnum Wieser, 1954, P. corniculata Gourbault, 1980, P. mirabile Cobb, 1917, P. multipapillatum Filipjev, 1922 and P. stomachor Wieser, 1954 but differs from them by tail length, longer posterior cylindrical portion of the tail, relative width of the amphidial fovea, position of the ventral pore and lesser number of supplementary organs. Desmodora striatocephala sp. nov. is well characterized by a combination of very large amphidial fovea occupying nearly the entire lateral surface of the cephalic capsule and thickened midventral preanal cuticle with a few supplementary papillae inserted therein in males. D. striatocephala sp. nov. differs from related species D. cuddlesae Inglis, 1963 and to some lesser degree with D. inflexa Wieser, 1954 with shorter body, relative tail length, bigger size of the amphidial fovea and lesser number of supplementary papillae.

The genus Pennella Oken, 1816, mesoparasitic copepods from marine fish and mammals, is reviewed with the objective of determining the validity of members of the genus. Details of the external morphological structures of the adult female are presented. Pennella species are differentiated based on a combination of characters: the type of host parasitized, overall length of the parasite, shape, size and configuration of cephalothoracic papillae, segmentation of the first and second antenna, holdfast horn number, shape and configuration, and structure of the abdominal plumes. A new species of Pennella, Pennella benzi sp. nov., is described from the escolar, Lepidocybium flavobrunneum in the northwest Atlantic. Pennella balaenoptera Koren & Danielssen, 1877 is reported from the harbor porpoise (Phocaena phocaena) in the Bay of Fundy, a new locality record. The validity of 44 species is assessed; nine species (P. balaenoptera Koren & Danielssen, 1877, P. benzi sp. nov., P. diodontis Oken, 1816, P. exocoeti (Holten, 1802), P. filosa Linnaeus, 1758, P. hawaiiensis Kazachenko & Kurochkin, 1974, P. instructa Wilson, 1917, P. makaira Hogans, 1988 and P. sagitta Linnaeus, 1758) are considered substantiated and valid; six species (P. elegans Gnanamuthu, 1957, P. longicauda Gnanamuthu, 1957, P. platycephalus Gnanamuthu, 1957, P. remorae Murray, 1856, P. robusta Gnanamuthu, 1957, and P. selaris Kirtisinghe, 1964) exhibit unique characteristics, but are based on descriptions of single specimens, have not been found since the original reports and are considered as species inquirendae; the remaining species are unsubstantiated and invalid based on inadequate or missing original descriptions, or are designated as synonyms of valid species. A key to the valid species of the genus is provided.

We revise the genus Acanthoctenus Keyserling, 1877 recognizing thirteen valid species, of which five are new species and two are re-validated. Further, we find one new synonymy and transfer one species. We describe Acanthoctenus alux sp. nov. from Guatemala, A. chickeringi sp. nov. and A. lamarrei sp. nov. from Panama, A. manauara sp. nov. from Brazil and A. torotoro sp. nov. from Bolivia. We revalidate Acanthoctenus dumicola Simon, 1906 stat. res. from Venezuela, and A. virginea (Kraus, 1955) stat. res., comb. nov. from El Salvador. We transfer Acanthoctenus mammifer to Viracucha mammifer (Mello-Leitão, 1939) comb. nov., from Brazil. Acanthoctenus maculatus Petrunkevitch, 1925 and Gephyroctenus kolosvaryi Caporiacco, 1947 are considered species inquirendae in Acanthocteninae and Ctenidae, respectively, and A. obauratus Simon, 1906 and A. rubrotaeniatus Mello-Leitão, 1947 are considered incertae sedis in Acanthocteninae and Acantheinae, respectively. We also describe for the first time the female of Acanthoctenus spiniger Keyserling, 1877, the type species of the genus. We provide illustrations of male and female diagnostic characters, genitalia, habitus, and measurements to support the genus re-description and further identification of its species. We yield a distributional map of the specimens recorded and the description of the natural history of Acanthoctenus manauara sp. nov.

The Neotropical species of the diplurid subfamily Masteriinae are revised and redefined. Masteriinae now comprises four genera, Masteria L. Koch, 1893, Striamea Raven, 1981, a new genus, Siremata n. gen. and Edwa Raven, 2015, a fossil genus. The type species, Masteria hirsuta L. Koch, 1893, was used as basis for comparison and the knowledge of the genus has increased. Twelve species of Masteria are redescribed and eight new species are described: M. amarumayu n. sp. and M. mutum n. sp., from Brazil; M. yacambu n. sp., from Venezuela; M. sabrinae n. sp., from Martinique; M. tayrona n. sp., from Colombia; M. aguaruna n. sp., from Peru, M. soucouyant n. sp., from Trinidad and Tobago; and M. galipote n. sp., from the Dominican Republic. Females of Masteria aimeae (Alayón, 1995) and M. golovatchi Alayón, 1995 are described for the first time. Females of M. spinosa (Petrunkevitch, 1925), M. petrunkevitchi (Chickering, 1964), M. lewisi (Chickering, 1964), M. barona (Chickering, 1966), M. downeyi (Chickering, 1966), M. simla (Chickering, 1966), M. colombiensis Raven, 1981 and M. pecki Gertsch, 1982 are illustrated for the first time and rediagnosed. Masteria tovarensis (Simon, 1889) and M. cyclops (Simon, 1889) are synonymized with M. lucifuga (Simon, 1889). Masteria modesta (Simon, 1892) is considered as species inquirendae and M. emboaba Pedroso, Baptista & Bertani, 2015 is considered as incertae sedis, as the type is lost. Both species of Striamea are revised and redescribed. A new genus, Siremata n. gen., is described and includes three Amazonian species: S. valteri n. sp., S. juruti n. sp., S. lucasae n. sp. Knowledge of the distribution ranges of the Neotropical Masteriinae are increased.
