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.

Habitat fragmentation and vegetation structure impact gastrointestinal parasites of small mammalian hosts in Madagascar

“…The supernatant was sieved with tap water into a new tube, where parasite stages were sedimented by centrifugation at 450×g for 5 min. The sediment was transferred into a counting chamber and parasite eggs, oocysts, and larvae were microscopically classified into morphotypes, based on different references for primate (Cameron, 1930;Chabaud et al, 1965;Rosario Robles et al, 2010;Hugot et al, 1995;Hugot & del Robles, 2011;Irwin & Raharison, 2009;Kalousová et al, 2014;Little, 1966;Radespiel et al, 2015;Raharivololona, 2006Raharivololona, , 2009 as well as rodent parasites (Baker, 2006(Baker, , 2008Bowman et al, 2004;Dewi et al, 2018;Khalil et al, 2014;Petrzelkova et al, 2006;Sambon, 1924;Smales et al, 2009;Thomas, 1924).…”
