(J013324.62+302328.4), (J013342.78+303256.3), (J013349.28+305250.2), (J013426.11+303424.7), (J013459.47+303701.9), (J013500.30+304150.9)

All six objects lack near-IR photometry, which renders it difficult to unambiguously classify them as B[e]SGs, although their mid-IR colors and their optical spectroscopic appearances support such a classification. The star J013342.78+303256.3 has even no mid-IR photometry, so that it is unclear whether it is surrounded by (warm) dust at all. There is an IR source at a distance of ∼4.5 arcsec which is considered as too far off to be identified with J013342.78+303256.3. The sources J013324.62+302328.4 and J013500.30+304150.9 were reported as intrinsically faint objects with little extinction, and were suggested as counterparts of the low-luminosity B[e]SG in the MCs [97]. However, according to the luminosity estimates for these stars, for which values of log *L*/*L* 4.8–5.0 were obtained [142], these stars fall rather onto the lower boundary of the high-luminosity B[e]SGs sample within the MCs (see Figure 1).
