The biology of the fungus-growing ants. Part. I. New forms. 1 Neal A. Weber, University of North Dakota Revista de Entomologia 1936 7 378 409 urn:lsid:biosci.ohio-state.edu:osuc_concepts:140605 Insecta Formicidae Mycetophylax CoL Animalia Mycetophylax brittoni var. littoralis Weber Hymenoptera 401 Arthropoda subSpecies brittoni littoralis  Fifteen worker cotypes. of brittoniwere compared with workers taken by myself along the east of Trinidad jupon many occasions. These specimens differ from the typical form in the following: Thorax in profile evenly convex instead of flattened; basal surface of epinotum separated from declivous surface by a pair of small but distinct tubercles, postpetiole from above distinctly longer than broad, sides and anterior margin forming an even convexity. Hairs of head somewhat shorter, finer, and more numerous. Color black with appendages dark brown. The brittonicotypes were distinctly paler in color though this may be caused by fading.  The males, 2.3-2.5 mm. in length, have the head, excluding mandibles, a trifle longer than wide back of eyes and the occipital margin straight with angulate corners. The epinotum is without tubercles but with a faint indication of angularity at the point where they would be situated. The color is black with dark brown appendages and pale brown mandibles. Wings hyaline, veins yellowish brown.  Type Colony: Mayaro Bay, Trinidad, B. W. I., March 11, 1935, N. A. Weber (63).
