Mesial surface and dorsal and ventral margins of chela smooth. Anterior branchial regions ornamented with short, oblique ridges anteriorly. Abstract Four new species of decapods and one new species of isopod are described from the Barremian Lower Cretaceous Arida Formation in Wakayama Prefecture, Japan.
This formation conformably overlies the Yuasa Formation and is unconformably overlain by the Nishihiro Formation Obata and Ogawa, 1976.
Outer orbital angle not produced. Feldmann and Rust 2006 listed 26 species referred to as Palaega.1992, from the Miocene of Japan is excluded here because Karasawa et al.
Dorsal surface gently convex transversely and longitudinally. 1995 moved it to Bathynomus A. II, Crustacea of the Gault and Greensand: Palaeontographical Society Monographs, London, 40 p. Intercalated plate narrow, longitudinally ridged; median suture following posterior end of intercalated plate, extending to posterior margin. I am grateful for the reviews by R. Subdorsal carinae weak, finely granulate, tapering distally, not reaching posterior end of supradorsal carinae.
Recent phylogenetic works suggested that the Podotremata is not monophyletic and paraphyletic, based upon the molecular analysis Ahyong and O'Meally, 2004; Ahyong et al. The crustaceans described herein were collected from the following localities : Loc.
Rostrum triangular; lateral margins smooth, very weakly concave, rimmed; dorsal surface smooth with median ridge.1998, Two new species of Decapoda Crustacea from the Upper Cretaceous Izumi Group, Japan: Paleontological Research, 2,217—223. Posterior margin narrow, more or less concave.
Abdomen fixed laterally by coxae of 1—2 anterior pairs of pereiopods.
