Abstract

A new genus, Tonsuritermes Cancello Constantini gen. nov., is described from South America. The main morphological features of the new genus are a remarkable frontal gland and protibia with two rows of spine-like bristles. Two new species of Tonsuritermes are described: T. tucki Cancello Constantini sp. nov. and T. mathewsi Cancello Constantini sp. nov. Comparisons, measurements, a map, histology of the frontal gland, and illustration of all fundamental morphological aspects are provided.
