Using a combination of near-infrared photometry from "Vista Variables in Via Lactea" ESO Large Public Survey, SDSS-IV APOGEE-2 spectra, and Gaia DR2 photometry and astrometry, we report on 29 OB type, Wolf-Rayet, and emission-line stars, 18 of which are newly classified. Most of these hot stars belongs to the main sequence, although some stars of class I are also proposed. The mean radial velocity is RV = -41.8 . The average spectroscopic distance is 3.2 +1.6 kpc, while the Gaia DR2 average distance is 3.7 +1.8 kpc. Eight objects show light-curve variations with amplitudes greater than 0.5 mag in the K S band. © 2019. The American Astronomical Society.
