Trachymyrmex relictus Borgmeier fitzgeraldi


Trachymyrmex relictus Borgmeier fitzgeraldi  HNS  ,

subsp. nov.

Worker: Length 2.9-3.5 mm. - This form differs from topotypes of T. relictus  HNS  chiefly in slightly smaller size, greater development of spines and tubercles, in darker color, and in more abundant pilosity. The occipital spines are distinct and surmounted by acute tubercles. Beneath these, on the Jateral margins, are several aggregations of irregular, acute tubercles. The lateral spines of pronotum are directed slightly forward, the tubercles of the mesonotum, epinotum, and pedicel are higher and more numerous than in the original illustration of relictus  HNS  .

The fine appressed hairs and the coarser reclinate hairs, especially on the gaster, are more numerous than in the topotypes; the thorax and gaster are darker, brown.

Described from a series of workers taken by myself April 23, 1935, in the Nariva Swamp, Trinidad, B. W. I.

This form is named in honor of my friend Mr. Desmond Vesey-Fitzgerald, my companion on this expedition into the swamp.
