Summary: | The genus Termes Linneus, 1758 consisting of a total of 24 valid named species known from the Old World, is a very heterogeneous group of termites and seems to involve many taxonomic obscurities and confusions. In the island of Sumatra, the sixth-largest island located in the Southeast Asian tropics, four species of Termes have been found, namely, T. comis, T. laticornis, T. rostratus, and T. propinquus. Termes propinquus is also known from Brunei, Indonesia (Kalimantan and Sumatra), Malaysia, and Thailand. However, previous authors have mentioned that T. propinquus has been poorly discriminated from the other congeners, especially T. rostratus. Therefore, the present study aimed at clarifying the discrimination of Termes propinquus from the morphologically similar congeners from Sumatra. A total of 14 nests were collected using a standardized sampling protocol and visual colony searching in Sumatra and its adjacent island. As a result of a careful morphological examination of the soldier caste, T. propinquus was discriminated from the three other congeners by a combination of the following characteristics: distinctly long frontal projection, larger head capsule, and 2nd antennal segment distinctly longer than the 3rd. The redescription of the soldier caste of T. propinquus and a key to Termes species known from Sundaland are provided. The nests of T. propinquus were attached to the bases of living trees, clinging to stumps or the bases of the dead tree, or were epigeal. |
