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 entoconid and hypoconulid cusps on the first two molars.

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.

[4] She found several living species in addition to two extinct ones that she described as new, Triaenops goodmani and Hipposideros besaoka.

[8] The specific name of the extinct species, goodmani, honors Steven Goodman for his research on Madagascan bats.

[10] In a 2008 paper, Amy Russell and colleagues commented that cranial (skull) characteristics of T. goodmani suggest it is a member of the "T. furcula/T.

[13] On m1, the trigonid (front group of cusps) is narrower and slightly higher than the talonid at the back.

[12] From the same site where T. goodmani was found, Samonds also recorded the distal (far) end of a Triaenops humerus (upper arm bone), with a width of 3.58 mm.
