Tetramorium notomelanum sp. n. is described from the Tehuacán Valley, state of Puebla, México. Its distribution and relation with other species of the tortuosum-group is discussed. The new species of Tetramonium is described from workers, and distinguished from others of the group by several characters: i) black coloration of the body; ii) size: T. notomelanum sp. n. is smaller than T. hispidum...

In this study we revise the taxonomy of the Tetramorium tortuosum species group members encountered in the Afrotropical region, which we have placed in its own subgroup: the Tetramorium capillosum species complex. We re-describe the two previously known species Tetramorium capillosum Bolton and Tetramorium tabarum Bolton, and describe the new species Tetramorium hecate sp. n. The geographic dis...

Spine deformations and faulty posture may be evaluated by assessing trunk surface deformation. POTSI index (Posterior Trunk Symmetry Index) was introduced in 2003 to assess asymmetry of the trunk seen from the back. However, deformations may also affect the anterior surface of the trunk and this can be noticed more easily by the patient owing to the visual accessibility of the anterior surface....
