Wadeura haskinsi , sp. nov.

(Fig. 7, b)

Worker.-Length, 4.4-4.6 mm. Head, excluding mandibles, distinctly longer than broad, roughly quadrangular with rounded corners and slightly impressed occipital margin. Antennal scapes failing to reach occipital margin by a distance greater than their distal diameter; 2nd joint of funiculus shorter than third; mandibles long and narrow, terminating in a slender, acute tooth, their outer margin feebly sinuate, their inner margin on the distal three-fifths with two large, stout, and blunt teeth, of which the more distal is larger, and a small median tooth between them; between the apical and the sub-apical tooth a slight rounded tubercle suggests a rudimentary tooth. Thorax in profile with distinct pro-mesonotal impression.

Other characters as in W. guianensis .

Described from three workers taken by my friend, Dr. Caryl Parker Haskins, who found these ants upon several occasions on Barro Colorado Island, Canal Zone and who successfully brought parts of colonies to the United States for study.

This species is close to W. guianensis but differs in larger size, mandibular tooth structure, shorter antennal scape, shorter 2nd joint of funiculus, and more distinct pro-mesonotal impression.
