Abstract
Cosmocerca vrcibradici (Cosmocercidae) and Physaloptera bainae (Physalopteridae) are two
intestinal nematodes obtained from a scincid lizard, Chalcides ocellatus (Scincidae). The study
gave the first morphological description of C. vrcibradici and P. bainae using light and scanning
electron microscopy. A cosmocercid nematode C. vrcibradici assigned to genus Cosmocera,
possessing small mouth surrounded by three lips provided with four sub-median cephalic
papillae and each one has a pair of lateral amphids. Male was 2.4-2.7 (2.6±0.1) mm
long; maximum width 0.2-0.23 (0.21±0.01) can be easily distinguished from its congeners by
the presence of lateral alae and small well sclerotized gubernaculum and ended conically with
a tapered tail. Females measured 1.9–3.7 (2.8±0.1) mm in length & 0.24–0.42 (0.38±0.01) mm
in width ended with a tapered tail. Besides, all recovered females were gravid filled with large
number of embryonated eggs. Physaloptera bainae assigned to genus Physaloptera characterized
by long robust body measured 3.21-5.47 (4.35±0.10) long and 0.58-0.65 (0.62±0.01) in
maximum width, oral openings with two semicircular pseudolabia, cuticle dilatation at anterior
extremity, reflected over base of lips, forming cephalic collar and ended posteriorly with tapered
tail. Only recovered parasites were females with didelphic uterus the main characteristics
feature among between species. These observations have allowed a more detailed description
of both nematode taxonomy and classification.
