Lateral view of thorax / mesosoma, adult. Mesosoma entirely sculptured. Note erect hairs (arrows) present on dorsum.
Lateral view of thorax / mesosoma, adult worker. The mesosoma is entirely covered in a punctate ground sculpture giving it a uniformly dull appearance. Used in Antkey to separate Monomorium pharaonis and the Monomorium salomonis-group from other Monomorium.
Lateral view of thorax / mesosoma, adult worker. The dorsal surface of the mesosoma may have appressed pilosity, but it lacks erect hairs. Used to distinguish species in the Monomorium salomonis-group (Monomorium salomonis and Monomorium subopacum) from all other Monomorium species in Antkey.

Anterior view of head, adult worker. The cephalic sculpture of Myrmica rubra is characterized by long longitudinal carinae that rarely intersect. Contrasts with the strongly reticulated cephalic sculpture of Myrmica specioides.
Anterior view of frontal carina, adult worker. The frontal lobes are narrow, distinctly longer than broad and taper anteriorly. Used in Antkey to separate Myrmica rubra from Myrmica specioides.
Anterior view of frontal carina, adult worker. Frontal lobes short and broad, distinctly rounded anteriorly. Photo by Erin Prado, Antweb.org, modified.

Anterior dorsal view of head, adult worker. Carinae on cephalic dorsum mostly longitudinal, occasionally branching, but rarely intersecting.
Anterior view of head, adult worker. The cephalic sculpture of Myrmica specioides is strongly rugoreticulate and characterized by longitudinal carinae that are frequently intersected by shorter transverse carinae. This character state contrasts with the predominately longitudinal cephalic carinae of Myrmica specioides that rarely intersect.
