چکیده
Recovery of new decapod specimens from middle and late Eocene rocks of Pakistan prompted reevaluation of the known decapod fauna of the region. Specimens come from the Sulaiman Range in Balochistan, North-West Frontier, and Punjab provinces, and range temporally from the middle Lutetian through the Bartonian and possibly early Priabonian global marine ages. Proxicarpilius planifrons, Portunus sp., Lobocarcinus indicus, and a new hermit crab (unnamed) are the longest-ranging stratigraphically. Gillcarcinus amphora and Hepatiscus sheranii appear to be restricted to Lutetian strata, while Hexapus pinfoldi and Bicarinocarcinus collinsi are restricted to Bartonian-Priabonian strata. Additional Bartonian-Priabonian taxa include a new species of ghost shrimp, Neocallichirus wellsi, and a new genus, Pakicarcinus, to accommodate Lobonotus orientalis Collins and Morris, 1978. Evaluation of the Pakistan species Lobonotus orientalis Collins and Morris, 1978, led to a revision of the extinct genus Lobonotus A. Milne Edwards, 1864. A new genus Lobulata is erected to accommodate Lobonotus lobulata Feldmann et al., 1995, from the Cretaceous-Danian of Argentina. Lobonotus vulgatus Quayle and Collins, 1981, is removed from the genus; however, examination of type material will be necessary to place that species within a genus. Lobonotus sensu stricto now embraces six North American species.
