  abstract = {{A}ssessing spider diversity remains a great challenge, especially in tropical habitats where dozens of species can locally co-occur. {P}itfall trapping is one of the most widely used techniques to collect spiders, but it suffers from several biases, and its accuracy likely varies with habitat complexity. {I}n this study, we compared the efficiency of passive pitfall trapping versus active nocturnal hand collecting ({NHC}) to capture low understory-dwelling spider taxonomical (morpho-species) and functional (hunting guilds) diversity along a structural gradient of habitats in {F}rench {G}uiana. {W}e focused on four habitats describing a structural gradient: garden to the orchard to the forest edge to the undisturbed forest. {O}verall, estimated morpho-species richness and composition did not vary consistently between habitats, but abundances of ground-hunting spiders decreased significantly with increasing habitat complexity. {W}e found habitat-dependence differences in taxonomic diversity between sampling strategies: {NHC} revealed higher diversity in the orchard, whereas pitfalls resulted in higher diversity in the forest. {S}pecies turnover resulted in high dissimilarity in species composition between habitats using either method. {T}his study shows how pitfall trapping is influenced by habitat structure, rendering this sampling method incomplete for complex, tropical environments. {H}owever, pitfall traps remain a valuable component of inventories because they sample distinct assemblage of spiders.},
