“…In their original descriptions of different species of Lemuricola Chabaud et al (1965) using light microscopy, described 3 pairs of pedunculated papillae, 2 pairs of sessile papillae, and 1 pair of amphids. In a previous study Robles et al (2010) demonstrated the presence of only 2 pairs of pedunculated papillae in L. (M.) bauchoti, a parasite of the ringtailed lemur, Lemur catta Linnaeus, in Madagascar. Using SEM microscopy, we also found only two pairs of pedunculated papillae (1st and 4th pairs) in L. (M.) vauceli.…”

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.

“…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).…”

Deleterious effects of habitat loss and fragmentation on biodiversity have been demonstrated in numerous taxa. Although parasites represent a large part of worldwide biodiversity, they are mostly neglected in this context. We investigated the effects of various anthropogenic environmental changes on gastrointestinal parasite infections in four small mammal hosts inhabiting two landscapes of fragmented dry forest in northwestern Madagascar. Coproscopical examinations were performed on 1,418 fecal samples from 903 individuals of two mouse lemur species, Microcebus murinus ( n = 199) and M. ravelobensis ( n = 421), and two rodent species, the native Eliurus myoxinus ( n = 102) and the invasive Rattus rattus ( n = 181). Overall, sixteen parasite morphotypes were detected and significant prevalence differences between host species regarding the most common five parasites may be explained by parasite–host specificity or host behavior, diet, and socioecology. Ten host‐ and habitat‐related ecological variables were evaluated by generalized linear mixed modeling for significant impacts on the prevalence of the most abundant gastrointestinal parasites and on gastrointestinal parasite species richness (GPSR). Forest maturation affected homoxenous parasites (direct life cycle) by increasing Lemuricola , but decreasing Enterobiinae gen. sp. prevalence, while habitat fragmentation and vegetation clearance negatively affected the prevalence of parasites with heterogenic environment (i.e., Strongyloides spp.) or heteroxenous (indirect cycle with intermediate host) cycles, and consequently reduced GPSR. Forest edges and forest degradation likely change abiotic conditions which may reduce habitat suitability for soil‐transmitted helminths or required intermediate hosts. The fragility of complex parasite life cycles suggests understudied and potentially severe effects of decreasing habitat quality by fragmentation and degradation on hidden ecological networks that involve parasites. Since parasites can provide indispensable ecological services and ensure stability of ecosystems by modulating animal population dynamics and nutrient pathways, our study underlines the importance of habitat quality and integrity as key aspects of conservation.
