Figure 5 - Ventrolateral views of the right orbital region in Sturnira bakeri (A, QCAZ 14635 ♀) and Sturnira luisi (B, ROM 104204 ♂) illustrating taxonomic differences in the shape of the sphenorbital fissure. In Sturnira bakeri, the sphenorbital fissure is oval (arrow). In Sturnira luisi, however, the sphenorbital fissure is semicircular (arrow).
