Diagnosis.

Four Loboscelidia species have a flattened cervical extension, including brunnea, maculipennis and Loboscelidia nitidula . Of these four Loboscelidia nitidula can be distinguished by presence of a scrobal sulcus, a medial metanotal ridge and a large foretibial flange (flange absent in the other species).
