A five-year-old, entire female mixed-breed dog was presented with corneal oedema and episcleral hyperaemia in the left eye. The ophthalmological examination revealed the presence of a free-swimming nematode in the anterior chamber. Circulating microfilariae were not observed by a modified Knott test nor were adult antigens detected in serum by a commercial ELISA. The parasite was surgically rem...

Abstract: Background: Hemiscorpius lepturus is a medically important scorpion found along the Iranian borders, especially near to Khuzestan Province in the south-west of Iran. This is the only non-buthid scorpion which is potentially lethal in southern Iran and is responsible for severe dermonecrotic scorpionism. OBJECTIVES: In this study, DNA fragment of the mitochondrial cytochrome c oxidase ...

Summary Specimens of a thin longidorid species collected in Peñalba (Huesca), north-west Spain, were previously described as Paralongidorus iberis . However, we conclude, through scanning electron microscopy and molecular studies on population from about 15 km the type locality paratype specimens, that this was originally placed wrong genus. Both populations have pore-like amphidial apertures, ...

There has been very little undisputed evidence for recombination in animal mitochondrial DNA (mtDNA) provided so far. Previous unpublished results suggestive of mtDNA recombination in the scorpion family Buthidae, together with cytological evidence for a unique mechanism of mitochondrial fusion in that family, prompted us to investigate this group in more details. First, we sequenced the comple...

The barcoding approach was applied to analyze 16 Australian morphospecies of the order Phasmida, with the aim to test if it could be suitable as a tool for phasmid species identification and if its discrimination power would allow uncovering of cryptic diversity. Both goals were reached. Eighty-two specimens representing twelve morphospecies (Sipyloidea sp. A, Candovia annulata, Candovia sp. A,...

A new species of the genus Synoecnema-S. watinagii sp. n.-is described and illustrated. The species is characterized by its small size, lack of sexual dimorphism apart from sexual characters, males with pericloacal disk, females with anterior vulva position and lacking an anus, and similar caudal organs in both sexes in the shape of long, deep slits on the surface of the posterior half of body....

In Mediterranean countries, Sarcophaga (Liopygia) crassipalpis, Sarcophaga (L.) argyrostoma, and Sarcophaga (L.) cultellata share the same ecological niche and can be responsible of myiasis. In this study, the main morphological characters of a larva found in a hospitalized woman were described and illustrated by light and SEM microscopy and the features discussed. Then, a fragment within the m...
