Specimen Labels


Known only from the male caste. The male caste is poorly known in the genus Simopone and this species may be the male of a species that presently has no associated males.


A member of the emeryi species group.

Little is known about the biology of most species of Simopone. Specimens are rarely collected, and the number of species known only from workers is telling in regards to a lack of nest samples. Species are almost entirely arboreal but on occasion foraging workers are found on the ground or in rotten logs. Prey records are extremely sparse. They consist only of Crematogaster brood by Simopone vepres, and the brood of Terataner by Simopone sicaria. Nevertheless, these two records support the general supposition by Brown (1975) that most or all members of tribe Cerapachyini prey on other ants, or more probably the brood of other ants, but actual records are extremely rare. (Bolton and Fisher 2012)



The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

  • mayri. Simopone ? mayri Emery, 1911: 16 (m.) MADAGASCAR. [Originally incorrectly described as males of Cerapachys mayri Forel, 1892: 244, by Emery, 1899: 264; misidentification.] Senior synonym of satagia (unnecessary replacement name): Bolton & Fisher, 2012: 57.
  • satagia. Simopone satagia Bolton, 1995: 383. Unnecessary replacement name for mayri Forel, sensu Emery, 1899: 264 (misidentification): Bolton & Fisher, 2012: 57.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


Bolton and Fisher (2012) note: This species was described from a couple of large Madagascan males that were originally thought by Emery (1899) to be the males of Lioponera mayri, a species previously described from workers by Forel (1892). Emery (1911) realised that he had probably placed them in the wrong genus, and transferred them to Simopone but indicated his reservations about this choice with a question mark in his 1911 citation. From the description alone, it is impossible to tell what the correct generic combination should be, as characters critical at genus-rank were all omitted. Examination of the two specimens has revealed that all the genus-rank characters of male Simopone are present in combination and the inclusion of mayri in Simopone is confirmed. However, these males have yet to be matched to any worker-based species as the syntypes of mayri differ from all other male samples, worker-associated or isolated, that are currently available. All that can be said at the moment is that S. mayri is a member of the emeryi group and appears to be related to Simopone rex, but differs by the characters given in the provisional key to males.
