Latagallina olsoni was named by Shute et al. (2017) [A species of Latagallina as defined by generic features of the tarsometatarsus and femur, and distinguished from other members of the genus by its small size and by the following unique combination of features. Tarsometatarsus: (i) The fossa infracotylaris and sulcus extensorius are very deep. (ii) The medial hypotarsal ridge is moderately deep in proximal aspect. (iii) The tuberositas m. tibialis cranialis is relatively short and not protuberant, and completely recessed within the sulcus extensorius. (iv) Trochlea metatarsi IV is only very slightly plantarly depressed relative to trochlea metatarsi III, as seen in distal aspect. Femur: (i) The proximocranial surface adjacent to the crista trochanteris has a deep pneumatic fossa.]. Its type specimen is WAM 15.9.6, a partial skeleton (associated remains of one adult individual, comprising the following elements: mandible, approximately 1.5 cm of tip; two vertebrae, one cervical, one caudal; 1), and it is a 3D body fossil. Its type locality is Leaena's Breath Cave, which is in a Pleistocene terrestrial horizon in Australia.
