Matsliah et al. (2024) - FBrf0260545 say this is similar to Tm21. Nern et al. (2025) - FBrf0262545 say it is similar to Tm14. Transmedullary neuron that terminates in lobula layer 4 with bleb-type arborizations. It displays fine arborizations in medulla layers M1, M2, M3, M8 and M9, and has bleb-type arborizations in layers M1, M2, M8 and M9.
