Both sexes are described on the basis of material caught in Egyptian waters off the Alexandria coast at Abuqir. The new species shares with Lernanthropus breviculus Kabata, 1979 the possession of a small dorsal plate on the trunk that is so narrow at its origin that it does not overlap the bases of the fourth legs, which are therefore visible in dorsal view. These species differ in the shape of the cephalothorax and in the extent of the dorsal plate, which is shorter in the new species, revealing the caudal rami in do...

This species can be distinguished from all other members of Heterocotyle Scott, 1904 by a combination of the morphology of the male copulatory organ, which is a short, slightly curved, sclerotised tube with no accessory piece, and the haptor, which has a single ridge surmounting all septa. This is the first Heterocotyle species to be described from the southwestern Atlantic.

The hosts are the combtooth blenny Parablennius zvonimiri (Kolombatovic) (Blenniidae), the mushroom goby Ponticola eurycephalus (Kessler) (Gobiidae), the tubenose goby Proterorhinus marmoratus (Pallas) (Gobiidae) and the black-striped pipefish Syngnathus abaster Risso (Syngnathidae). The new species is most similar to its closest relative, Acanthocephaloides propinquus (Dujardin, 1845), in proboscis shape and armature (12 longitudinal rows of 5 hooks) and the shape of the trunk, reproductive system and lem...

To date, all Philornis species that have been recorded from Argentina have parasitic subcutaneous larvae. Here, for the first time for Argentina, we report the finding of Philornis downsi Dodge & Aitken, 1968, a fly with a nest-dwelling, semi-haematophagous larva. This record, from the humid Chaco ecoregion of Argentina in the nest of a saffron finch Sicalis flaveola pelzelni Sclater, substantially extends the known distribution of this species. We also report the consensus sequences of the internal transcribed spacer 1 (ITS1) and ITS2 regions of ...

The new species is distinguished from D. paradoxus Kearn, Whittington & Evans-Gowing, 2010 by its larger size, body shape, lack of transverse ridges on the ventral surface and absence of a seminal receptacle. Extensive short gut branches lie dorsal to the testes and adjacent to the coiled region of the vas deferens and the oötype, possibly reflecting high metabolic demand in these areas. Denticles are present in the lining of the nasal fossae of G. typus, providing a firm substrate for the cement-based attachment of a microbothriid. However, confirmation that D. cairae inh...

Traditionally, morphometric approaches are based on the use of arbitrary collections of linear distance measurements between landmarks. An exhaustive review of the specific diagnoses published in the journal Systematic Parasitology highlights the fact that an intricately important number of measurements are used to describe the same morphological features. Hence, this does not allow relevant comparison between studies and may have caused confusion in the literature. More importantly, a significant proportion of diagnoses commonly used do not maximize the amount of information available from morphological features, and sets of linear measureme...

The characters of the ovary of Amphilina japonica are different from those of all other cestodes. The most important difference is in the nature of the relationship between the germ and accessory cells within the ovary. In A. japonica the oocytes and accessory cells form numerous different intercellular contacts (desmosome-like junctions and zonulae adherentes). Gap junctions are present between the narrow cytoplasmic processes of the accessory cells. Numerous micropinocytotic vesicles and vacuoles from the accessory ...

It is especially a problem in banana cultivation, where the nematodes' feeding reduces yields and causes toppling disease. It has been suggested that the genus Radopholus Thorne, 1949 might have an Australian origin, but the native range of R. similis (Cobb, 1893) is not well known. Here we undertake a phylogeographical study of samples of R. similis from banana plantations down the eastern seaboard of Australia, with additional samples from Costa Rica and accessions from GenBank, to examine the origin of pest populations of R. similis.

Both molecular data-sets show that M. pectinata (Goeze, 1782) and Schizorchis caballeroi Rausch, 1960 are sister species and that they are phylogenetically independent from M. ctenoides (Railliet, 1890). This shows unambiguously that Mosgovoyia [sensu Beveridge (1978)] is a non-monophyletic assemblage, supporting the validity of Neoctenotaenia Tenora, 1976, erected for M. ctenoides. The results also show that the morphologically related Ctenotaenia m...

Several nominal species have been shown to represent complexes of morphologically cryptic biological species, a situation potentially confounding the analysis of ecological data. A software tool, 'Proboscis profiler', was developed to detect morphological heterogeneity in collections of superficially similar acanthocephalan worms based on the multivariate statistical analysis of proboscis hook dimensions. Proboscis profiler identifies objective, natural groups in a collection of acanthocephalans which may correspond to distinct biological species or populations. Initial trials demonstrate that Proboscis profiler can discriminate biological...

Ultrastructural studies have revealed their affiliation within the alveolates, which was confirmed by the phylogenetic analysis of the ribosomal RNA gene (SSU rDNA) sequences of two species of Thalassomyces Niezabitowski, 1913. However, their precise systematic position within this group remains unresolved, since they could not be definitively allied with any particular alveolate group. To better determine the systematic position of ellobiopsids by molecular phylogeny, we sequenced the SSU rDNA from the type-species of the Ellobiopsidae, Ellobiopsis chattoni Caullery, 1910....

It is closest to the Australian species P. pseudocaranxi Dove & Cribb, 1998, but differs in its shorter cirrus-sac extending only to the level of the ovary rather than to the level of the testes, in lacking eye-spot pigment and in details of the armature of the terminal genitalia. P. pseudocaranxi of Machida (2005) is regarded as identical to the new species. The validity of Allobacciger Hafeezullah & Siddiqi, 1970, as distinct from Monorcheides Odhner, 1905, is discussed. A key to the six species of Paramonorcheides Yamaguti, 1938 is presented. PMID: 19424791 [PubMed - in proces...

They designated a neotype for the type-species, D. perpusilla, from a sample of specimens ex Chelon labrosus off West Thurrock, UK. The morphology of the material (three specimen lots) studied by these authors was re-examined in detail and compared with their data. The material labelled 'D. perpusilla' from off West Thurrock, from which the neotype specimen was selected, consists of 14 specimens; of these one might belong to Haploporus Looss, 1902 and one to Haplosplanchnus Looss 1902. A well-developed genital atrium was observed in 11 of the 12 remaining specimens, and they all possess large saccular caeca and a vitellariu...

(Digenea: Cryptogonimidae) is described from the fish Nemipterus furcosus (Val.) (Perciformes: Nemipteridae) from off New Caledonia (South Pacific). Adlardia n. g. is distinguished from all other cryptogonimid genera by the combination of an elongate body, the presence of oral spines, intestinal caeca that open via ani at the posterior end of the body, a highly lobed ovary, oblique testes that are located in the mid-hindbody, vitelline follicles that extend from midway between the testes and ovary to midway between the ovary and ventral sucker, and an excretory vesicle that bifurcates dorsal to the ovary and reunites immediately anterior to the pharynx. A. novaecaledoniae n. sp. is the on...

(Monogenea: Ancyrocephalidae) is described from the gills of the orbfish Ephippus orbis (Bloch) (Ephippidae) off the Island of Langkawi, Malaysia, in the Andaman Sea. This new genus has the ancyrocephalid characteristics of four anchors, 14 marginal hooks and two bars, but differs from other four-anchored monogenean genera, and notably from Parancylodiscoides Caballero & Bravo Hollis, 1961 (found on the ephippids Chaetodipterus spp. off Central and South America), by having a unique combination of features. These include a muscular genital sucker and a vas deferens and vagina on the same (sinistral) side of the body. It is similar to Parancylodiscoides in having four haptoral reservoirs opening at the anchoral apertur...

(Cystidicolidae), are described from the digestive tract of the marine deep-water fish, the Mediterranean grenadier Coryphaenoides mediterraneus (Giglioli), from the Mid-Atlantic Ridge. The former species is characterised mainly by the structure of the mouth (large pseudolabia, each with well-developed dorsal and ventral extension and small apical protrusion; submedian labia almost absent), the large, elongate-oval, non-filamented eggs (60-66 x 18-27 microm), a cervical inflation of the cuticle, bifurcate deirids, and the length of the spicules (315-360 and 120-147 microm), whereas the latter (only males available) can be distinguished by the length of the spicules...

A new subfamily, the Testudotaeniinae, is erected. The new taxon differs from all proteocephalidean subfamilies in the position of the genital organs in relation to the longitudinal internal musculature, i.e. the testes are cortical, rarely medullary; the ovary is partly medullary, with cortical lobes; the vitelline follicles are mainly medullary, with some follicles in the cortex; and the uterus is cortical. A key to the subfamilies of the order Proteocephalidea Mola, 1928 is provided. The most characte...
