Von Ovalau (einer der Viti-Inseln); im Museum Godeffroy in Hamburg.

Ich bin nicht vollkommen sicher, dass die hier diagnosticirten Arbeiter, Weibchen und Maennchen zum zuerst beschriebenen Soldaten, den ich als Typus fuer die neue Art betrachte, gehoeren, da ich nur weiss, dass alle Geschlechter von Ovalau stammen. Das Weibchen gehoert ohne Zweifel zu dieser Art, der Arbeiter aber nur wahrscheinlich, ebenso auch das Maennchen, indem die Eigenschaften keinen sicheren Schluss erlauben und ueberhaupt die Verschiedenheiten der Arten bei diesen meist sehr geringe sind.
