Taxonomy
Laelaps macropus was named by Cope (1868). Its type specimen is AMNH 2250–2253, a set of limb elements (partial tibia, pedal phalanx II-1, pedal phalanges III-2, MT IV, MT III), and it is a 3D body fossil. Its type locality is G. C. Schenck Farm, which is in a Maastrichtian marginal marine marl in the Navesink Formation of New Jersey. It is the type species of Teihivenator.
It was recombined as Dryptosaurus macropus by Hay (1902), Huene (1927) and Miller (1955); it was synonymized subjectively with Coelosaurus antiquus by Matthew and Brown (1922), Hay (1930) and Steel (1970); it was considered a nomen dubium by Holtz (2004) and Holtz et al. (2004); it was recombined as Teihivenator macropus by Yun (2017).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C.-g. Yun 2017 | Tyrannosauroid theropod diagnosed by following autapomorphies: medial tibial condyle is triangular, whereas lateral tibial condyle is round; medial tibial condyle is positioned higher than lateral tibial condyle; small tubercle is present between the well-separated medial and lateral tibial condyle; intercondylar notch is deep and “I” shaped; cnemial crest can be seen at the posterior view of proximal tibia; lateral malleolus is at same level as medial malleolus; paired ventral processes proximally on all preserved pedal phalanges. |
