Isolation of Mandibular Gland Reservoir Contents from Bornean 'Exploding Ants' (<em>Formicidae</em>) for Volatilome Analysis by GC-MS and MetaboliteDetector

The aim of this manuscript is to present a protocol describing the metabolomic analysis of Bornean &#39;exploding ants&#39; belonging to the Colobopsis ...

A taxonomic description of all castes of  Laciny & Zettel,  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  (COCY) group and falls into a species complex that has been repeatedly summarized under the name  (Emery, 1889) (formerly ). 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:  Laciny & Zettel,  and  (Smith, 1857). Characters of male genitalia and external morphology are compared with other selected taxa of Camponotini. Preliminary notes on the biology of  Laciny & Zettel,  are provided. To fix the species identity of the closely related , a lectotype from Singapore is designated. The following taxonomic changes within the  complex are proposed:  (Menozzi, 1926),  and  (Menozzi, 1926),  are synonymized with  Roger, 1863, a common endemic species of the Philippines.  Stitz, 1925, ., hitherto a subspecies of , is raised to species level.

 sp. n., model species for studies on "exploding ants" (Hymenoptera, Formicidae), with biological notes and first illustrations of males of the  group.
