Specimen Labels



This species can be separated from the rest of the mariae complex species as the dorsopropeum is mainly smooth (reticulated in Aenictus hitai) and does not present the lateropropodeal pubescence characteristic to Aenictus steindachneri. Separation of minors from Aenictus boltoni can be difficult at first sight, but the petiole is clearly lower (PPI: 138 [130-150], PPI: 113 [107-127] in A. boltoni) and hemispherical while it’s subquadrate with straight parallel anterior and posterior sides in A. boltoni. The metapropodeal suture is almost non-existent in A. mariae minors but clearly visible in A. boltoni, both laterally and dorsally.

Separation from A. boltoni minors as in the following table.

Postpetiolar shape PPI Metapropodeal suture
A. boltoni Low, semispherical 113 [107–127] Visible, both laterally and dorsally
A. mariae High, subquadrate with straight parallel anterior and posterior sides 138 [130–150] Faint and not discernible in minors
