These cells are found in PB glomeruli 1-8, but not 9 (Wolff et al., 2015; Hulse et al., 2021). They usually target the round body contralateral to the PB glomerulus they innervate, but the glomerulus 1 cells target all three regions in the same hemisphere, though this may be the opposite hemisphere to the cell body position (Wolff et al., 2015; Hulse et al., 2021). PFR_a PB1-glomerulus-FBc,d>IDFPL-RB PFR_a appears to be the subtype identified in Wolff et al. (2015), based on comparison of wiring diagrams - Fig 22 in Wolff et al. (2020) & Fig 30 in Hulse et al. (2021). This subtype was renamed in Wolff and Rubin (2018) from PBG1-8.s-FBl3,4,5.s.b-rub.b to PBG1-8.s-FBl3,4,5.s.b-ROB.b due to earlier (Wolff et al., 2015) misidentification of round body as rubus. Probably also the subtype identified by Lin et al. (2013) if G1 and G2 were both identified as G1 (existing G1 identified by Wolff et al. 2015), as G5 (called G4 in ref) links to central FB. The specific 'horizontal fiber system neurons' (HFS) described by Hanesch et al. (1989) probably also correspond to these neurons (Wolff et al., 2015). Lin et al. (2013) consider HFS to be equivalent to their PFI neurons - any neuron connecting PB, FB and IDFP (lateral accessory lobe/crepine). HFS
