basiconic sensillum of antennal segment 3 obsolete antennal basiconic sensillum ab11 2013-11-22T17:27:06Z https://github.com/FlyBase/drosophila-anatomy-developmental-ontology/issues/2107 true fly_anatomy.ontology Olfactory basiconic sensillum, located on the lateral surface of the antenna, that houses the dendrites of three olfactory receptor neurons (Kwon et al., 2010). It responds strongly to citronellal, dependent on TRPA1 expression in one of the sensory neurons (Kwon et al., 2010). Obsoleted as this was not molecularly-defined and likely represents a variant of another basiconic sensillum type (Benton et al., 2025). FBbt:00110666
