Myrmecia infima

Several workers swept from flowers by Dr. Darlington and myself near Government House (X. 21, '31, and X. 22, '31) and White Hill (X. 23, '31). According to Clark, who records this diminutive bull-dog ant from Rottnest Island, it occurs along the West Australian coast from Geraldton to Albany. I have taken it at Geraldton, in King's Park, Perth, and at Margaret River, always on flowers or foliage, but have never been able to find its nest. (Wheeler 1934)

Identification
Heterick (2009) - The taxonomy of the M. urens species-group is problematic, and most named taxa (including Myrmecia infima described from Perth, and Myrmecia nigra, described from East Fremantle) cannot be identified with any confidence based on morphological characters. However, possibly three species from this group are represented in the SWBP.

Distribution based on Regional Taxon Lists
