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 ).
