Triaenops goodmani is an extinct bat from Madagascar in the genus Triaenops. It is known from three lower jaws collected in a cave at Anjohibe in 1996, and described as a new species in 2007. The material is at most 10,000 years old. A bat humerus (upper arm bone) from the same site could not be identified as either T. goodmani or the living T. menamena. T. goodmani is identifiable as a member of Triaenops or the related genus Paratriaenops by a number of features of the teeth, such as the single-cusped, canine-like fourth premolar and the presence of a gap between the and hypoconulid cusps on the first two molars. T. goodmani is larger than the living species of Triaenops and Paratriaenops on Madagascar, and on the first molar the cusp is only slightly higher than the hypoconid, not much higher as in the other species.
In 1996, a team led by David Burney collected breccias containing remains of bats and other animals from the cave of Anjohibe in northwestern Madagascar. The bats in the sample were described by Karen Samonds (previously Irwin) in her 2006 Ph.D. dissertation and a 2007 paper. She found several living species in addition to two extinct ones that she described as new, Triaenops goodmani and Hipposideros besaoka. At the time, the genus Triaenops was thought to include three species on Madagascar–Triaenops auritus, Triaenops furculus, and Triaenops rufus. Since then, Steven Goodman and Julie Ranivo have discovered that the name rufus is not in fact applicable to the Madagascar species and proposed the name Triaenops menamena for the Madagascan bats previously known as Triaenops rufus.
In addition, Petr Benda and Peter Vallo have removed the other two Madagascan species to a separate genus Paratriaenops, so that they are now known as Paratriaenops auritus and Paratriaenops furculus. The specific name of the extinct species, goodmani, honors Steven Goodman for his research on Madagascan bats. The material of T. goodmani is from locality OLD SE within the cave and is about 10,000 years old or younger. A cladistic analysis using morphological data could not resolve the relationships of Triaenops goodmani, but did not place it with the other species of Triaenops and Paratriaenops studied. In a 2008 paper, Amy Russell and colleagues commented that cranial (skull) characteristics of T. goodmani suggest it is a member of the "T. furculus/T. auritus group", now placed in Paratriaenops.
