Distribution covers the marine littoral environments. from Brazil, Cuba, Gambia, Bahrain, Malaysia (Sabah), Singapore, and Sri Lanka (Murphy, 1971).</p> <p>The species was described from Brazil and dedicated to Professor Paulo Sawaya (so the correct name is Pseudanurida sawayai and not P. sawayana, as originally described and cited in many articles). In the same year of Schuster’s description, Murphy (1965) characterized and illustrated a series of specimens from Gambia, including the complete dorsal chaetotaxy, which were identified as Pseudanurida cf. bogoyawlenskyi (Baker, 1905); however, later Murphy (1971) recognized that those specimens were actually of P. sawayai.</p> <p>The species was described from Brazil (Recife: Barra das Jangadas) in a creek connecting Rio Pirapama and Rio Jaboatão, a few km South of Piedade Marine Biol. Station, in mangroves; nevertheless after Murphy (1971) it also has been found in Gambia (West Africa) in mangroves and rocky shore; Sabah (North Borneo), Labuan on weed-covered rocks, small inlet inside Labuan town at low tide; Singapore, Pasir Ris, sparse mangroves by small stream; Bahrain, Persian Gulf, edge of inland, fresh-water stream (maybe of artesian origin); Ceylon, Mendel lake (a brackish lagoon on the West coast) and in Mannar, Giant’s tank (a large, inland, artificial fresh-water lake). It was found by Christiansen &amp; Bellinger (1988) in mangroves of Puerto Rico, and also under and on rocks in Florida, USA. Now is has been found in sandy beach, so it seems that this species can live in different habitats.</p></div> 	https://treatment.plazi.org/id/03A687AEFFDBFFA69BB3FBAADF61C221	Public Domain	No known copyright restrictions apply.

This species name is dedicated to both Professor Jian-Xiu Chen, retired professor from Nanjing University and Professor Jian Chen from Hubei University of China, for their contributions to the knowledge of Collembola taxonomy and spider’s biology, respectively, and for their friendship and help given to the authors for many years.</p> <p>Remarks. Oudemansia chenorum sp. nov. has small anal spines a2 (a1&gt; a2), so it seems related with Oudemansia subcoerulea Denis, 1948, O. dubia Denis 1947 and O. petiti Delamare Deboutteville &amp; Massoud, 1964. Oudemansia petiti is similar to O. esakii Kinoshita, 1932 but differs in the number of manubrial setae (14 vs. 20). The new species has same kind of male genital organs as O. petiti but differ in the number of mandibular teeth, which are very numerous in P. petiti (20) and in two rows. In P. chenorum sp. nov. the anal spines have different length and seta a3 is normal. Oudemansia petiti lacks Oc2 and Oc1 is short (very long in the new species) and one dental seta is distally displaced from the other five.</p> </div>	https://treatment.plazi.org/id/03A687AEFFD8FFAD9BB3FCB5D8A7C6A5	Public Domain	No known copyright restrictions apply.
