Description
Worker
Length 2.3-2.6 mm.
Differing from the typical form in being decidedly larger and more robust; head larger and broader; joints 2-5 of the funiculi decidedly longer, the second distinctly longer than broad, the third and fourth as long as broad. Petiolar scale as in the typical form, with entire or very feebly and broadly sinuate superior border. In profile this border is decidedly thicker and blunter; the posterior pedunculate extension of the petiole well-developed as in the typical form.
Erect hairs on the body, scapes and tibia' even more numerous and longer. Coloration more vivid, the mandibles and head being deep red, the latter blackish behind, the thorax and appendages of a more reddish yellow tint than in the typical Myrmelachista ramulorum.
Type Material
Described from nine specimens taken by Dr. F. E. Lutz, seven from Mona Island (type-locality) and two from Porto Rico, without more precise locality.
