Front produced, sinuously triangular, rostrum with a moderately deep median sulcus, supraocular angle scarcely produced, depressed by a shallow groove.

Chelae large, slender, transversely swollen; outer margin curved on entire length, unarmed; fingers spineless, frequently gaping in larger chela. Gape of fingers with large, dense pubescence, visible from above, sometimes only in one chela, seldom lacking. Ischium of walking legs covered with a pubescence of feathered setae; merus with a single dorsal spine close to the distal edge in L1 and L2, and a fringe of feathered setae on anterior margin; merus of L1 and L2 with a posterodistal spine, sometimes lacking in L2 or in both. Carpus and propodus with a fringe of feathered setae on anterior margin, with scattered feathered and simple setae. Propodus ventrally with distal triplet of movable spinules and one additional spine at mid-distance; dactylus with 3 movable spines on posterior margin.</p><p>Variation.</p><p>Large specimens normally present more elongate and narrower chelipeds, more variation in the form of the chelipeds than smaller ones, and often exhibit a remarkable heterochely.</p><p>Habitat.</p><p>Petrolisthes inermis seems to be a shallow water species. According to the material of the Papua New Guinea Expedition and the two Snellius Expeditions in Indonesia the species was collected in the littoral in rocky beaches and on dead corals, in depths of 0-5 m.</p><p>Distribution.</p><p>Eastern Indian Ocean, Nicobar Islands, Indonesia, Papua New Guinea, New Caledonia.</p><p>Remarks.</p><p>Some of the original material from the Novara Expedition is deposited in the collections of the Naturhistorisches Museum (NHM) in Vienna. We found two lots labelled as “Syntypus” of Porcellana inermis Heller, 1862. One lot (NHM24237) contained a moderate-sized female, which was selected as lectotype. The other (NHM24238) contained a small male lacking the right chela and two walking legs, and a larger female lacking one cheliped. The small male was selected as paralecto type . The second specimen represents a different species. De Man´s (1893) original specimens of Petrolisthes tenkatei (RMNH.CRUS.D.2604, RMNH.CRUS.D.1643) are deposited in the collections of the Naturalis Biodiversity Center (Leiden). They are labelled as lectotype and paralectotypes of Petrolisthes tenkatei, which is a synonym of Petrolisthes inermis . Judging from the figure of Petrolisthes sp. n. from De Man (1902, fig. 37) this species also corresponds to Petrolisthes inermis, and is therefore included in the synonymy of that species.</p></div>	https://treatment.plazi.org/id/442783D7684D21228C5D38DD6DA22717	Public Domain	No known copyright restrictions apply.
