    Polyrhachis
    (genus)
    Taxonomy: Animalia: Arthropoda: Insecta: Hymenoptera: Formicidae: Polyrhachis
    Kate Sandiford says

    Rose, there are so many golden spiny ants in the north and they are not all 'ammon'. This one has spines at the front corners of the pronotum (first thoracic segment) which puts it in the subgenus Hedomyrma rather than Hagiomyrma which have rounded pronotal shoulders.
