AbstractGravid females of the little-known dracunculoid nematode Mexiconema liobagri Moravec et Nagasawa, 1998 (Daniconematidae), a parasite of the rare endemic catfish Liobagrus reinii Hilgendorf (Amblycipitidae), were found in the body cavity of this fish from two new localities in Japan: the Takami River at Kotsugawa, Higashiyoshino, Nara Prefecture and the Tenryu River at Ina, Nagano Prefecture, representing the second record of this nematode species since its original description. Light and scanning electron microscopical examinations of these specimens enabled us to supplement the original description of M. liobagri and to recognise biometrical variability in this species. Details of the cephalic structure of M. liobagri (presence of the small triangular mouth armed with six denticles, surrounded by a pair of large lateral amphids and four submedian pairs of small cephalic papillae) are described for the first time. In addition to M. liobagri, another specific nematode parasite, Rhabdochona japonica Moravec, 1975, was recorded in the intestine of L. reinii from the Takami River.

Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.

AbstractThree nematode species of Cithariniella (Pharyngodonidae), C. citharini, C. khalili, and C. gonzalesi, were recorded from the recta of squeaker (Mochokidae: Siluriformes) and citharinid (Citharinidae: Characiformes) fishes from Senegal, West Africa. Morphological characteristics obtained by scanning electron microscopy (form of oral aperture and cephalic papillae, presence of lateral alae, distribution and form of cloacal papillae, simple or paired papillae on tail of males, eggs with numerous long filaments on each pole in females) correspond well to the generic diagnosis and represent species differences. The shape and size of the cephalic papillae and lips were identified as a new determination feature. C. gonzalesi is reported for the first time from Senegal and its host, Paradistichodus dimidiatus, represents a new host record. A tentative simple key for differentiating C. citharini, C. khalili, C. gonzalesi and C. petterae is provided based upon these results.

AbstractThe life cycle of two morphologically very similar Diplogasteroides species and their association with cockchafers in southern Germany was investigated. 70-100% of cockchafer grubs and 95% of the imagines carried Diplogasteroides spp. dauer juveniles. The nematodes were almost exclusively found on the external cuticle of the insects and usually not in the body cavity or the intestine. Diplogasteroides spp. dauer juveniles embark on the grub and accumulate during its development. There was some indication that dauer juveniles are transmitted from male to female beetle during copulation. The dauer juveniles resume development only after the death of the beetle, feeding on the cadaver (necromeny). Former hypotheses, assuming the nematode species to be parasitic and to cause the death of cockchafer grubs, can be refuted.

AbstractA new nematode species, Foleyellides rhinellae sp. nov. (Onchocercidae), is described from specimens found in the body cavity of the cane toad, Rhinella marina (Linnaeus) (Anura, Bufonidae), in the Laguna de Coyuca, Guerrero, in the Pacific slope of Mexico. The new species differs from the other nine species of Foleyellides by infecting bufonid anurans and by the number and arrangement of caudal papillae. Other distinguishing feature of the new species is the size of the left spicule (0.16–0.23 long), the smallest recorded among the species included in the genus. Foleyellides rhinellae sp. nov. is the second known species of the genus recorded from amphibians of Mexico.

Abstract Finding male philometrid nematodes is essential for taxonomic identification among congeneric species. In this study, male Philometra thaiensis Moravec, Fiala et Dyková, 2004 were collected and described for the first time, from the body cavity of the freshwater fish (eyespot pufferfish) Tetraodon biocellatus Tirant (Tetraodontiformes, Tetraodontidae), and conspecific females were redescribed based on the additional morphological biometrics examined. Molecular examination was carried out on the small subunit 18S rRNA, revealing the evolutionary relationships of P. thaiensis and reported philometrid species (Philometra and Philometroides) from Japan with other dracunculoids deposited in the GenBank. Based on the molecular data, there are some genera (Philometra, Philometroides, Clavinema, and Margolisianum [genus inquirendum]) requiring further morphological re-evaluation that should be supported with molecular data.

AbstractTwo little-known nematode species of the family Camallanidae, intestinal parasites of marine perciform fishes, are reported from off New Caledonia: Procamallanus (Procamallanus) annulatus Yamaguti, 1955 from the goldenlined spinefoot Siganus lineatus (Valenciennes) (Siganidae) and Procamallanus (Spirocamallanus) monotaxis (Olsen, 1952) from the longspine emperor Lethrinus genivittatus Valenciennes and the slender emperor Lethrinus variegatus Valenciennes (both Lethrinidae). Detailed light and electron microscopical studies (the latter used for the first time in these species) revealed some taxonomically important, previously not observed features, such as the presence of deirids, six crescent-shaped elevations surrounding the mouth, three poorly developed protuberances on the female tail tip and circumcloacal papillae and phasmids on the male tail in P. annulatus, and the presence of a circumoral flange, only 12 (instead of 14 reported) cephalic papillae, the shape of deirids and similar numbers (14–17 and 14–15) of spiral ridges in the male and female buccal capsules in P. monotaxis. The fourth-stage larva of P. annulatus is described for the first time. Firststage larvae of both species were found to possess several digital processes at the tail tip. The present findings represent new host and geographical records of these parasite species.

Moringua edwardsi is recorded for the first time at Atol das Rocas, northeastern Brazil. Previous records of the species were located in the western Atlantic Ocean, from Florida to southeastern Brazil, but with many gaps between these regions. A single specimen was collected in Atol das Rocas in July 2007 and it is deposited in the Dias da Rocha Ichthyological Collection. The new record of M. edwardsi fills a geographic distribution gap of this species and complements the inventory of fish species inhabiting one of the most unique marine protected areas in the world.

Abstract. A male representative of the extinct species Calomicrus eocenicus Bukejs et Bezděk, 2014 (Chrysomelidae: Galerucinae) is found and described for the first time from Eocene Baltic amber using X-ray microtomography. The aedeagus is well preserved within the body cavity of the specimen, and it is illustrated in detail. This fossil species exhibits distinct sexual dimorphism: the male has a smaller total body size, as well as a copula-adapted modification in abdominal ventrite 5 (apical margin deeply trilobed, with round medial fovea present); meanwhile the female is larger in body size and has a simple abdominal ventrite 5 (without fovea, non-incised and widely rounded apically). Similar sexually dimorphic characters are typical for extant members of the tribe Luperini, and this report is the first time that they are described in an Eocene species. The known sexually dimorphic characters present in Coleoptera within Eocene Baltic amber are briefly discussed.
