Anochetus boltoni Fisher, 2008 |
Collected three times in rotten logs and once in a leaf litter sample. Males have been collected in malaise samples on 20–25 Dec 2004 at 488 m in Parc National de Marojejy, Madagascar.
Identification
The species is most similar to Anochetus goodmani, but can be easily distinguished by its petiole node with a pair of large apical spines (Fisher and Smith).
