Material additional examined: 21♂ , 33♀ . (Appendix I). Diagnosis. Large individuals. Only member of the group with angled tegula ( Fig. 5A ). Redescription. Male:As described for Z. brasiliensis except: Coloration: black head except: apex of clypeus reddish; mesopleura, metapleura, metanotum, propodeum, petiole ventrally and legs red-orange. Structure: Tegula with posterior margin angled; the anterior surface of the mesepisternum micro-striate; S5 and S6 with robust ligulate processes. Sculpture: Strio-punctuation above the carina interantennal less evident. Chaeototaxy: Yellowish; T3 to T7, hairiness is not so visible. Female:As described for the male except: Coloration: Clypeus all black; antennae without yellowish areas. Structure: Clypeus without concavity and apical teeth; mandible tetradentated with the third tooth molariform; anterior face of the mesepisternum without micro-stries. Sculpture: Absence of transverse interantennal carina and frontal strio-punctuation. Variations: Some specimens, both males as females, feature a variation about the coloring in the following parts: clypeus almost completely reddish in males and at least two-thirds in females; mandibles and gena reddish; petiole may be from completely dark until completely red. This gradient of coloration was used for differentiation of the subspecies Z. m. mexicanus , Z. m. erythrogena and Z. m. lugubris .
