We carried out a survey of infrared star clusters and stellar groups on the 2MASS J, H and Ks all-sky release Atlas in the Northern and Equatorial Milky Way (350 ◦ <�< 360 ◦ ,0 ◦ <�< 230 ◦ ). The search in this zone complements that in the Southern Milky Way (Dutra et al. 2003a). The method concentrates efforts on the directions of known optical and radio nebulae. The present study provides 167 new infrared clusters, stellar groups and candidates. Combining the two studies for the whole Milky Way, 346 infrared clusters, stellar groups and candidates were discovered, whereas 315 objects were previously known. They constitute an important new sample for future detailed studies.

• Revisiting the population of Galactic open clusters (2005, methodology): “According to Bica et al. (2003b) the gap is well filled by 45 embedded clusters detected in the 2MASS atlas.”
• A systematic survey for infrared star clusters with |b| < 20° using 2MASS (2006, background): “Recent work by Dutra et al. (2003) and Bica et al. (2003) proved that 2MASS indeed contains hundreds of previously unidentified infrared clusters.”
• The Bubbling Galactic Disk. II. The Inner 20° (2007, background): “A search of current catalogs of SNRs (Green 2004), PNe (Kerber et al. 2003), WR stars (van der Hucht 2001, 2006), and open clusters (Dutra et al. 2003; Bica et al. 2003) found no positional coincidences with any of the bubbles in GII.”
• The second data release of the INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS DR2) (2014, background): “…which have only recently started to become revealed by efforts to catalogue the wealth of ‘bubbles’ detected at mid-infrared wavelengths (Churchwell et al. 2006; Simpson et al. 2012), and by efforts to catalogue previously unknown clusters seen in the near-infrared (e.g. Bica et al. 2003).”
• Multiple populations in globular clusters (2012, background): “(2007): the globular clusters must have been initially a large factor (10-100) more massive than today and almost all the first generation stars must have been preferentially lost.”
• 109 new Galactic open clusters (2005, background): “Dutra et al. (2003) and Bica et al. (2003) searched the 2MASS for compact embedded clusters in the direction of known nebulae.”

(2006, hereafter FMR06) made the discovery of an unprecedented cluster of 14 RSGs at a Galactic longitude of l ¼ 25 , hereafter known as RSGC1.”
