Morphological and infraciliature studies carried out using pyridinated ammoniacal silver carbonate and the 4’,6-diamidino-2-phenylindole (DAPI) staining techniques, led to the identification of two new species of ciliates pertaining to the subclass Astomatia. The first species, Hoplitophrya polymorphus sp. nov., displays two main cellular forms: the elongated form (150–247 μm long and 40–87 μm width) and the stocky form (140–170 μm long and 70–98 μm width). The macronucleus is generally skinny in the elongated forms and ribbon-shaped in the stocky forms. The common feature of the two cellular shapes uniting them in the same species is the identical structure of their skeletal apparatus, a V-shaped element located in an apical depression and bearing skeletal fibres on its ventral face. The second species, Anoplophrya simplex sp. nov., is totally deprived of skeletal apparatus. The cell shape is fusiform and dorsoventrally flattened (105–180 μm long and 65–125 μm width). Six to 12 pulsatile vacuoles form two rows arranged symmetrically on either side of the macronucleus. These two newly identified species highlight the extremely rich diversity of ciliates inhabiting the digestive tract of tropical earthworms.

The nematode genus Bulbocephalus Rasheed, 1966 (Nematoda, Physalopteridae) was found to be a homonym of Bulbocephalus Watson, 1916 (Apicomplexa) and, therefore, a new name, Rasheedia n. nom., is proposed to substitute it. Based on light and scanning electron microscope studies of specimens collected from the digestive tract of perciform fishes off New Caledonia, two new species of Rasheedia are described: R. heptacanthi n. sp. from the Cinnabar goatfish Parupeneus heptacanthus (Mullidae) (type host) and Dentex fourmanoiri (Sparidae), and R. novaecaledoniensis n. sp. from the Indian goatfish Parupeneus indicus (Mullidae). These new species are mainly characterized by the number of anterior protrusible oesophageal lobes (two in R. heptacanthi and four in R. novaecaledoniensis), structure of the oesophagus and the lengths of spicules. An amended diagnosis of Rasheedia and a key to species of this genus are provided. Three previously described congeneric species are transferred to Rasheedia as R. deblocki (Le-Van-Hoa, Pham-Ngoc-Khue & Nguyen-Thi-Lien, 1972) n. comb., R. inglisi (Rasheed, 1966) n. comb. and R. pseudupenei (Vassiliadès & Diaw, 1978) n. comb. Cestocephalus Rasheed, 1966 [genus inquirendum], including C. serratus Rasheed, 1966 and C. petterae (Le-Van-Hoa, Pham-Ngoc-Khue & Nguyen-Thi-Lien, 1972) n. comb., should be considered to be separate from Rasheedia. The names Pseudomazzia Bilqees, Ghazi & Haseeb, 2005 and P. macrolabiata Bilqees, Ghazi & Haseeb, 2005, established for a nematode somewhat resembling Rasheedia spp., should be considered nomina dubia. Rasheedia heptacanthi n. sp. and R. novaecaledoniensis n. sp. are the first representatives of the Physalopteridae recorded from fishes in New Caledonian waters.

The main features of the life-history of Mermis nigrescens, so far as it is known, are briefly discussed. Some data have been collected on its distribution in the British Isles, and on the seasonal appearance of the egg-laying females. The insect hosts of the worm are discussed, and feeding experiments on various invertebrates are recorded, including the experimental infection of the common earwig (Forflctila auricularia). This insect, which has also been found naturally infested, is regarded as an important host for the species, more especially where grasshoppers are absent. Observations by other workers on the influence of the number of larvae per host on the sex of the developing worms, and on the survival of the host, have been confirmed. Two new species, closely related to M. nigrescens, are described: M. kenyensis and M. tahitiensis, from Africa and Tahiti respectively.

Mites (Acari, Acariformes, Parasitiformes) are one of the most diverse and abundant groups of arthropods associated with birds. Several families of mites have colonised the respiratory tract of birds, the Rhinonyssidae (Mesostigmata) being the most diverse. There are 66 species of rhinonyssids (59 named, seven undescribed species) reported from Canadian birds. Two new species of rhinonyssids were discovered while surveying nasal mites from birds in Manitoba, Canada, and are herein described as Sternostomagallowayisp. n. from the horned lark (Eremophilaalpestris), and Vitznyssusericisp. n. from the common nighthawk (Chordeilesminor).

Two new jellyfishes are described from the waters off northwestern Australia. The first, Carukia shinju n. sp., is similar to the common Queensland Irukandji Carukia barnesi, but differs from the latter in having a larger body size, branched velarial canals, nematocyst warts on both the velarial canals and the perradial lappets, fully-spined tentacular nematocyst shafts, about 14 naked ringlets between adjacent tentacular nematocyst bands, and long, narrow, capitate rhopaliar horns. The second, Malo maxima n. gen. n. sp., is distinctive from other known cubozoan species by its unique combination of having a tall, narrow, robust body with a flattened apex; frown-shaped rhopaliar niche ostia; short, broad, straight rhopaliar horns; small, narrow pedalia with a single row of nematocyst patches on the outer keel and fine, cylindrical unmodified tentacles; moderately developed perradial mesenteries; 4 simple to bifurcated velarial canals per octant arising from a single base; and lacking both gastric phacellae and a thorn-like diverticulum of the pedalial canals. Both species are thought to be dangerous to humans, causing Irukandji syndrome.

Two new endosymbiotic turbellarians from the 20-rayed crinoid Promachocrinus kerguelensis are described from specimens collected off the western coast of the Antarctic Peninsula. Desmote antarcticus sp.n. differs from previously described members of the genus in the shape of the penis stylet, orientation of the terminal branches of the ovaries, and connections of the genital ducts to the exterior. Parafallacohospes bransfieldensis gen. et sp.n. is distinctive among known umagillids in having a pair of broad lobes projecting from each side of the body. The anatomy of the reproductive system is similar to that of Fallacohospes inchoatus Kozloff except that P. bransfieldensis lacks a secondary uterus. In addition, P. bransfieldensis has a functional digestive tract with small intestinal ceca, whereas F. inchoatus, the only species in the genus Fallacohospes, lacks a digestive tract. In this respect, Parafallacohospes appears to be intermediate between Desmote, which has large intestinal ceca, and Fallacohospes. Both new species belong to the subfamily Bicladinae, which includes all other crinoid-inhabiting umagillid flatworms.

During recent investigations on Endamoeba blattae (Bütschli) Leidy of the common cockroach, Blatta orientalis, there were observed in the hindgut of the host, two other distinct amoebic species. Both appear to be truly entozoic, but contrast strikingly with E. blattae both in morphological features and life cycle. They are interesting not only in being among the comparatively few species yet reported from insects, but also in their relationships to certain of the amoebae of vertebrates.

Fourteen species of Chalcidoidea (Encyrtidae, Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae and Torymidae) were obtained from the common reed, Phragmites australis (Cav.) Trin. ex Steud. (Poaceae) in the Urmia region, in the northwest of Iran. Among these species, two new species of Pteromalidae are described hereafter: Norbanus persicus Lotfalizadeh & Rasplus sp. nov. and Stenomalina delvarei Lotfalizadeh & Rasplus sp. nov. Anagyrus near alienus Japoshvili, 2002, Asitus sp., Cheiloneurus paralia (Walker, 1837), Echthroplexiella obscura (Hoffer, 1952), Neococcidencyrtus poutiersi (Mercet, 1922) (all Encyrtidae), Aprostocetus orithyia (Walker, 1839) (Eulophidae), Eupelmus phragmitis Erdös, 1955 (Eupelmidae), Aximopsis deserticola (Zerova, 2004) comb. nov., Tetramesa phragmitis (Erdös, 1952) and Tetramesa sp. (all Eurytomidae), Homoporus febriculosus (Girault, 1917) (Pteromalidae) and Torymus arundinis (Walker, 1833) (Torymidae) were also obtained from our laboratory rearing. Nine of these species are recorded for the first time from Iran.
