Catalogue of the hymenopterous insects in the collection of the British Museum. Part VI. Formicidae. Author Smith, F. text 1858 British Museum London http://antbase.org/ants/publications/8127/8127.pdf book 8127 Genus 5. MYRMICARIA . Myrmicaria , Saund. Trams. Ent. Soc. Land. iii. 57. This genus of Ants is founded on characters derived from males only: in all probability the genus Physatta, the characters of which are derived from females, may prove to be the other sex of Myrmicaria ; specimens of both genera have been received from India, Java, and Port Natal, but it appears desirable to keep them separate until further information is obtained; in the genus Myrmicaria , the antennae are 13-jointed, those of Physatta being 7-jointed; the labial and maxillary palpi 3-jointed.
