Synhimantus [Synhimantus] laticeps [Rudolphi, 1819] Railliet, Henry et Sisoff, 1912 [Nematoda, Acuariidae] parasitic in Tyto alba [Gmelin] [Aves, Tytonidae] in Argentina

During the parasitological examination of the barn owl Tyto alba (Gmelin), from Mar Chiquita coastal lagoon in Argentina, specimens belonging to Synhimantus (S.) laticeps (Rudolphi, 1819) Railliet, Henry et Sissof, 1912 were obtained. Comparison of measurements of present specimens with Cram and Smogorzhevskaya’s description of the same species, revealed several dissimilarities in the metrical features which cannot be considered great enough to create a new species. This new record of S. (S.) laticeps represents the first citation of this nematode from South America, and contributes to the knowledge of the morphology of this species, giving complete measurements and a detailed description of spicules. In addition, morphological and evolutionary considerations regarding fourth larval stages and subadults of S. (S.) laticeps, are also presented in this paper.

Aviculariella alcedonis (Spirurida, Acuariidae) is recorded from Alcedo atthis (Coraciiformes, Alcedinidae) from Bulgaria (new geographical record). A description of female specimens based on light-microscopy and SEM studies is presented. On the basis of the observations of the cephalic end, the position of the genus is considered to be in the subfamily Acuariinae, not in the Seuratiinae where it was previously placed. The host range of Aviculariella spp. is recognised as restricted to birds of the family Alcedinidae. A new morphological peculiarity described in A. alcedonis is the presence of a pair of sublateral ribs at the anterior end of each pseudolabium.

Acuaria subula (Dujardin, 1845) is redescribed by light microcopy (LM) and scanning electron microscopy (SEM) on the basis of specimens from its type host, Erithacus rubecula (Passeriformes, Muscicapidae), from Curonian Spit (Kaliningradskaya Oblast’, Russia) and Bulgaria. Acuaria skrjabini (Ozerskaya, 1926) is redescribed by LM and SEM on the basis of specimens from Passer domesticus (type host) and P. hispaniolensis (Passeriformes, Passeridae) from Bulgaria. Contrary to previous opinions recognizing A. skrjabini as a junior synonym of A. subula, the present study confirms that they are distinct species. They can be distinguished on the basis of the ratio between the length of cordons and the body length, the ratio between the length of muscular oesophagus and glandular oesophagus, and the ratio between the total length of oesophagus and the body length. In addition, the plates forming the cordons in these two species exhibit different morphological characters. Another difference between these two species is associated with the particular irregular mosaic ornamentation of the cuticle on the ventral and lateral sides of body around the region of vulva of A. subula and its absence in A. skrjabini. Data on their host and geographical ranges are surveyed. The type series of Acuaria buttnerae Chabaud et Petter, 1961, described as a parasite of Calandrella brachydactyla (Passeriformes, Alaudidae) in France, is re-examined; the latter species is recognized as a junior synonym of A. skrjabini (new synonymy).

The acuarioid nematode Echinuria skrjabiniensis Efimov in Skryabin, Sobolev et Ivashkin, 1965 was found in Calidris bairdii and C. fuscicollis (Aves, Scolopacidae) examined from several locations from Patagonia, Argentina. These constitute new host records as well as the first record of this parasite species in South America. Using both light and scanning electron microscopies, new morphological details are provided, including the description of the left spicule and the number and the arrangement of male caudal papillae. The taxonomic history of the species is summarized, corroborating its correct spelling and valid name.

Decorataria decorata (Cram, 1927) is redescribed on the basis of light-microscopy and SEM observations on specimens collected from the stomach of Podiceps cristatus and P. grisegena from Bulgaria. The SEM study revealed the presence of a porebearing field on each pseudolabium and a pair of spines (one dorsal and one ventral) situated between bases of the cordons. The deirids are spine-like and minute. The light-microscopy examination showed the presence of ornamentation situated under the dorsal surface of caudal alae. The occurrence of D. decorata in Bulgaria is a new geographical record.
