INTRODUCTION: Porrocaecum semiteres (Zeder, 1800) (Ascaridida: Ascaridoidea) occurs frequently in various birds in Europe. However, the knowledge of the morphology of this species remains insufficient.
METHODS: Light and scanning electron microscopy were used to study the detailed morphology of adults of P. semiteres based on newly collected specimens from Turdus philomelos in the Czech Republic.
RESULTS: Some previously unreported morphological features were revealed, including the presence of a medio-apical notch, 70-80 small conical denticles and one pair of submedial pores on each lip, the absence of caudal alae, the presence of four pairs of postcloacal papillae, and a single, medio-ventral precloacal papilla.
