Abstract:
A taxonomic description of all castes of Colobopsisexplodens Laciny & amp; Zettel, sp. n. from Borneo, Thailand, and Malaysia is provided, which serves as a model species for biological studies on “exploding ants” in Southeast Asia. The new species is a member of the Colobopsiscylindrica (COCY) group and falls into a species complex that has been repeatedly summarized under the name Colobopsissaundersi (Emery, 1889) (formerly Camponotussaundersi ). The COCY species group is known under its vernacular name “exploding ants” for a unique behaviour: during territorial combat, workers of some species sacrifice themselves by rupturing their gaster and releasing sticky and irritant contents of their hypertrophied mandibular gland reservoirs to kill or repel rivals. This study includes first illustrations and morphometric characterizations of males of the COCY group: Colobopsisexplodens Laciny & amp; Zettel, sp. n. and Colobopsisbadia (Smith, 1857). Characters of male genitalia and external morphology are compared with other selected taxa of Camponotini. Preliminary notes on the biology of C.explodens Laciny & amp; Zettel, sp. n. are provided. To fix the species identity of the closely related C.badia , a lectotype from Singapore is designated. The following taxonomic changes within the C.saundersi complex are proposed: Colobopsissolenobia (Menozzi, 1926), syn. n. and Colobopsistrieterica (Menozzi, 1926), syn. n. are synonymized with Colobopsiscorallina Roger, 1863, a common endemic species of the Philippines. Colobopsissaginata Stitz, 1925, stat. n ., hitherto a subspecies of C.badia , is raised to species level.
