  abstract = {{T}he diversity of sensory systems in animals has poorly been explored on a phylogenetic basis at the species level. {W}e addressed this issue using cricket cerci, comprising abdominal appendages covered with touch- and air-sensitive hairs. {S}canning electron microscopy measurements and spatial analyses of hair positioning were used to quantify the structural diversity of cercal structures. {E}ighteen {E}neopterinae and two {G}ryllidae (outgroups) were studied from a phylogenetic perspective. {C}erci were revealed to be complex, diverse, and variable between cricket species. {B}ased on maximum likelihood estimations, the ancestral {E}neopterinae cercus had a small size, and its hair equipment allowed the use of both air and touch mechanoreception. {T}he evolution of {E}neopterinae cerci was mainly unconstrained by the phylogeny; it was rather a punctuated process, involving apical transformations, and was mostly unrelated to environmental patterns. {A}ll studied species have enhanced their overall perceptive capacities compared to the ancestor. {M}ost have longer cerci with more and/or longer hairs. {S}ensory abilities have improved either in the direction of touch or air movement detection, or both, without discarding the potential for any sensory capacity that was already present ancestrally. {T}his pattern is consistent with the hypothesis of an evolutionary trade-off for sensory performances.},
