{Messor medioruber}Forel's (1905b) description simply states (my translation) - "identical to aegyptiaca Em. but "submutique", seemingly with angular tubercles rather than edentate. Differs from minor in having a brown head. Much smaller than meridionalis - TL 3 to 6 mm. Queen - TL 10 mm, entirely black". Santschi's (1910a) description is at {original description} Santschi's (1927c) description of sublaeviceps is at {original description} Santschi's (1927c) descriptions of montanus and maura is at {original description}.

{Messor medioruber}The photomontage of a worker from Tunisia, as in the Santschi (1927c) records for laeviceps is collated from

{Messor medioruber maurus}The photomontage is of a specimen from Egypt, taken by Mostafa Sharaf. This clearly differs from the type form and has the red colour and minute propodeal spines referred to by Santschi (1927c).
