Abstract: © 2019 S. Karger AG, Basel. All rights reserved. Confiscated slow lorises (Nycticebus spp.) at Bangpra Water-Bird Breeding Center (BWBC) in Thailand provided an opportunity to demonstrate the application of noninvasive genetic approaches for species identification when morphology of the animals was ambiguous. The slow lorises at BWBC had been assigned to either N. bengalensis or N. pygmaeus, based on body size. However, the morphology of N. bengalensis is highly variable and overlaps with that of N. coucang (sensu stricto). Phylogenetic analysis of cytochrome b and d-loop mitochondrial regions placed all confiscated N. pygmaeus with the published sequences of N. pygmaeus and distinguished them from other Nycticebus. All other confiscated individuals formed a monophyletic clade, most individuals grouping with published N. bengalensis sequences from wild populations in Vietnam and distinct from Peninsular Malaysian and Sumatran N. coucang, Javan N. javanicus and Bornean N. menagensis. Six individuals within the N. bengalensis clade formed a separate subgroup that did not group with any reference material as indicated by phylogenetic and haplotype network analyses. Whether these trafficked individuals are undiscovered wild populations will require further investigation. Additional genetic studies of wild slow loris populations in different regions are therefore urgently required for reference to aid the protection and conservation of these threatened species.
