We carried out a 2MASS J, H and Ks survey of infrared star clusters in the Milky Way sector 230 <'< 350. This zone was the least studied in the literature, previously including only 12 infrared clusters or stellar groups withjbj< 10, according to the recent catalogue by Bica et al. (2003). We concentrated eorts on embedded clusters, which are those expected in the areas of known radio and optical nebulae. The present study provides 179 new infrared clusters and stellar groups, which are interesting targets for detailed future infrared studies. The sample of catalogued infrared clusters and stellar groups in the Galaxy is now increased by 63%.

• Revisiting the population of Galactic open clusters (2005, methodology): “Bica et al. (2003a) compiled a list of 276 embedded infrared star clusters and stellar groups from the literature and were able to increase the number by 346 new compact and remote objects associated with nebulae by making use of the 2MASS data (Dutra et al. 2003; Bica et al. 2003b).”
• The Bubbling Galactic Disk. II. The Inner 20° (2007, background): “Association with OB Clusters Twelve star clusters have been identified in 2MASS data (Dutra et al. 2003) in the northern survey area and nine in the southern area, but none of these are coincident with GII bubbles.”
• Triggered massive-star formation on the borders of Galactic H II regions I. A search for "collect and collapse" candidates (2004, unknown): “An IR cluster (no. 45 in Dutra et al. 2003) lies at the western edge of a faint optical nebulosity (Fig.”
• 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.”
• 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.”
• A Massive Cluster of Red Supergiants at the Base of the Scutum-Crux Arm (2007, methodology): “Using catalogs of Galactic plane cluster candidates (Bica et al. 2003a, 2003b; Dutra et al. 2003), Figer et al. (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.”

(2003), Dutra et al. (2003), Froebrich et al. (2007), Froebrich et al. (2010), Bukowiecki et al. (2011), and other sources.”
• Discovery of an Extraordinarily Massive Cluster of Red Supergiants (2006, methodology): “Bica et al. (2003a,b) and Dutra et al. (2003a) created a catalog of massive cluster candidates using an algorithm to search the 2MASS survey (Skrutskie et al. 1997, 2006)1.”
• New infrared star clusters in the Northern and Equatorial Milky Way with 2MASS (2003, methodology): “Recently, Dutra et al. (2003b) have observed most of them deeper and at higher angular resolution with the ESO NTT telescope: 31 turned out to be blended star images in the 2MASS Atlas, while 27 were confirmed as clusters or remain as cluster candidates.”
