It lies at the root of the median bundle, behind the prow (Ito et al., 2014). It forms the dorsal part of the adult tritocerebrum, developing from the centromedial and dorsal domains of the larval tritocerebrum (Hartenstein et al., 2018). fly_anatomy.ontology VFB:FBbt_00045050 FBbt:00045050 The flange corresponds to the dorsoposterior part of the subesophageal ganglion (SOG) of Chiang et al. (2011) and to part of the anterior periesophageal neuropils (Ito et al., 2014). PENPa anterior perioesophageal neuropils TRd
