摘要

A new homolid crab Lindahomola n. gen., with Lindahomola longispina n. sp., is reported from the Late Cretaceous (late Maastrichtian) of the Rocky Point Member of the Peedee Formation (North Carolina, USA). Lindahomola longispina n. gen., n. sp. possesses peculiar characters not shared with any known genus within the Homolidae. These characters include two very short pseudorostral spines, supraorbital margin continuous marked by a pair of short supraorbital spines, trif d antennal spine, one prominent anterolateral spine directed upward, with three supplementary basal spines, and one straight prominent subhepatic spine directed outward, with upper margin bearing a row of four small spines. Lindahomola n. gen. represents the second homolid crab from the Peedee Formation after the recent report of Peedeehomola GARASSINO, CLEMENTS & VEGA, 2015.
