Polyrhachis rufipes

Identification
A member of the Polyrhachis furcata species group.

Distribution based on Regional Taxon Lists
Indo-Australian Region: Borneo, Indonesia, Malaysia, Philippines. Oriental Region: Laos, Myanmar. Palaearctic Region: China.

Biology
Workers of P. rufipes use the trails of Stictoponera menadensis to gain access to sugar sources. When they encounter Stictoponera foragers, ''P. rufipes workers show a typical aggressive antennal boxing, to which Stictoponera'' reacts submissively (Gobin, Peeters, and Billen 1998). This is the only known instance of commensalism between an ectatommine and a formicine ant.
