OTHER GENERA INCLUDED. — Eopaguropsis Fraaije, Krzemiński, Van Bakel. Krzemińska & Jagt, 2012 and Paguropsina Lemaitre, Rahayu & Komai, 2018 ( Fig. 11 ). ETYMOLOGY. — The name is derived from the type genus. DIAGNOSIS. — Prominent subtriangular rostrum, considerably exceeding lateral projections.Cervical and branchial grooves subparallel, encompassing small branchial regions (= lateral lobes) or forming broad, sinuous groove. Shield well calcified, subtriangular or subrectangular; dorsal surface slightly vaulted with incomplete midline crest; welldelineated massetic region covered with numerous setal pits; posterior carapace less calcified, delineated cardiac region; uropods and telson symmetrical. Chelipeds subequal, similar in armature and setation.
