title: First description of myxozoans from Syria: novel records of hexactinomyxon, triactinomyxon and endocapsa actinospore types.
abstract: Oligochaete worms collected in late March and early April 2005 from 3 freshwater biotopes in Syria were surveyed over an 11 wk period for myxosporean parasites (Myxozoa). Three types of novel actinospore stages were identified from 1 host species, Psammoryctides albicola. A hexactinomyxon was found in 6 P. albicola (7.5%) collected from a branch of the River Orontes, north of the city of Hama. A triactinomyxon and an endocapsa were found in single P. albicola specimens from the Al-Thaurah region of the Euphrates River (Lake Assad). No oligochaetes collected from Al-Ghab fish farm (Orontes region) released actinospores during the observation period. The present study is the first description of myxosporeans, including actinospore stages, from Syria. The 3 types described herein differ morphologically and molecularly (18S rDNA) from published records.
