Material examined. COLOMBIA: Magdalena • 27 workers; Pivijay; 10°27′00″N, 074°36′00″W; alt. 3 m; Nov. 1985; A. Madrigal leg.; MEFLG 4272 ; Magdalena • 14 workers; Pivijay; 10°27′00″N, 074°36′00″W; alt. 3 m; May 1986; A. Madrigal leg.; MEFLG 4822 .

Identification. Antennal scapes surpass posterior corners of head by 1–2 times their maximum diameter; clypeus with row of coarse, long hairs on anterior margin; in side view, a few shorter erect hairs often present posterior to the anterior row; preocular carina relatively short, stopping at about 1/3 the distance between eye and posterior corner of head; frontal carina long, reaching back to posterior corner of head; anterolateral prome- sonotal tooth long, sharply pointed, projecting forward and upwards; propodeal teeth sharply pointed, approxi- mately as long as the distance between their bases; gas- ter strongly tuberculated, in dorsal view tubercles form four more or less distinct longitudinal ridges on first gas- tric tergite; and color dark reddish-black or gray-black, appendages and two petiolar segments usually a lighter reddish-brown ( Rabeling et al. 2007).

Distribution. Mycetomoellerius jamaicensis was previously recorded from the Caribbean island arc, Flor- ida (USA), and Venezuela ( Deyrup 2003, 2016; Jaffé and Lattke 1994; Mayhé-Nuñes and Brandão 2007; Rabeling et al. 2007). Our new record from Magdalena department in northern Colombia extends the distribution along the northern South American mainland ( Fig. 1C ).
