Redescription of Lemuricola (Madoxyuris) vauceli (Nematoda, Oxyuridae) from Eulemur fulvus (Primates, Lemuridae)

Abstract

Lemuricola (Madoxyuris) vauceli Chabaud, Brygoo et Petter, 1965 is redescribed on the basis of a re-examination of type and voucher specimens. Using both light and SEM microscopy, structures such as the cephalic papillae, details of the lateral alae, area rugosa and tail cuticular ornamentation, are described or redescribed with more precision. The detailed measurements of several male and female specimens are given in a table. In the original description, using light microscopy only, the authors had described 3 pairs of pedunculated papillae in the male of L. vauceli. The present study establishes the precise number, shape and disposition of the end of the male tail to include only two pairs of pedunculated papillae, 2 pairs of sessile papillae, and 1 pair of phasmids. As the same pattern was observed in all descriptions and recent redescriptions of species classified in the Enterobiinae, the present work confirms that the number and disposition of the caudal papillae observed in the subfamily is constant.
