title: A new species of open-air processional column termite, Hospitalitermes nigriantennalis sp. n. (Termitidae), from Borneo.
abstract: A new species of open-air processional column termite is here described based on the soldier and worker castes from eight colonies in north Barito, central Kalimantan. Hospitalitermes nigriantennalis sp. n. is readily distinguished in the field from related Hospitalitermes spp. by the light brown to orangish coloration of the soldier head capsule that, further, is with vertex yellowish and nasus brownish. The soldier antenna and the maxillary and labial palps are blackish. By contrast, soldiers from other species of Hospitalitermes from this region have a uniformly black head capsule and antennae. Finally, Hospitalitermes nigriantennalis sp. n. has a minute indentation in the middle of the posterior part of head capsule, which further helps to differentiate this new species from other Hospitalitermes from the Indo-Malayan and Austro-Malayan regions.
