Abstract
Two new lecithodendriid trematodes were discovered in the mouse-tailed bat, Tadarida pumila (Cretzschmar, 1830), from Ibadan, Western Nigeria: Maxbraunium nigeriense sp. n. and Prosthodendrium (Paralecithodendrium) ovulum sp. n. Each has been described and compared with closely related species. One hundred fourteen bats were examined for parasites during an undergraduate expedition to Western Nigeria from July to September 1966. Of these, 25 mouse-tailed bats, Tadarida pumila (Cretzschmar, 1830), harbored 174 gut trematodes of two different species of the family Lecithodendriidae. MATERIALS AND METHODS The bats were trapped in a 36-mm mesh, 4shelf Mist net as they left their roost each evening, and killed with an injection of Nembutal before the worms were removed and fixed in AFA. A variety of stains were used: acetocarmine, Grenacher's alum carmine, alcoholic carmine hydrochloride, Ehrlich's hematoxylin and acetic acid hematoxylin (Chubb, 1962). Five of the worms were serially sectioned. Measurements are in microns, unless otherwise stated, with mean figures in parentheses. A camera lucida was used to draw figures of the new species. Maxbraunium nigeriense sp. n. (Figs. 1, 2) One hundred three specimens were found in the pyloric region of the stomach of 16 Tadarida pumila. The following data have been collected from 18 worms.
