anterior pharyngeal organ [FBbt_00002687]

Sensillum of the lateral part of the embryonic/larval dorsal pouch (Campos-Ortega and Hartenstein, 1997. It contains a single neuron (first seen at embryonic stage 15) that is located dorsal to Bolwig’s nerve (at stages 16-17) and fasciculates with the lateropharyngeal nerve (SN-V). (Campos-Ortega and Hartenstein, 1997, Schmidt-Ott et al., 1994)

Sensillum of the lateral part of the embryonic/larval dorsal pouch (Campos-Ortega and Hartenstein, 1997.

Schmidt-Ott et al., 1994 tentatively assign this to the mandibular segment on the basis of its fasciculation pattern. This evidence is much weaker than the genetic evidence they use to determine the segmental identity of other head sensilla.
