Five pedigerous somites visible, the first short. Pereopod 2 6-articulated. Uropod endopod 2- articulated.</p><p>Remarks. At present, the combination of these morphological characters, in Day’s diagnosis (1978), except for “ uropod rami shorter than peduncle” (subequal in a Iphinoe crassipes specimen ibid), is enough for the identification of the genus in the subfamily Bodotriinae . Thereafter, Haye (2007) described rather more detailed morphological characters of the genus but showed that each character exhibits considerable variation between species. Therefore, it is difficult to include other characters in the diagnosis above.</p></div>	https://treatment.plazi.org/id/677387C4F346FFD7D6E9FBCEFA3FFA0F	Public Domain	No known copyright restrictions apply.

Uropod (Fig. 8G) peduncle 1.0–1.1 times pleonite 6 length, 1.2–1.5 times as long as exopod, 0.9–1.0 times as long as endopod, with 5–6 spiniform setae; exopod 0.7 times as long as endopod, with 4–8 spiniform setae on outer margin, five robust setae on apex; endopod biarticulate, article 1 1.7–1.9 times as long as article 2, with 6–7 spiniform setae on inner margin; article 2 with 2–3 spiniform setae on inner margin and two terminal setae.</p><p>Paratype 1 juvenile female, 4.2 mm. The specimen is very similar to the ovigerous and preparatory females. Dorsal region of pereonite 1 narrow, visible on dorsal region .</p><p>Etymology. The species’ name refers to the type locality, the Sulu Sea.</p><p>Remarks. The new species is closely similar to Iphinoe crassipes Hansen, 1895 from the west coast of Africa and the Mediterranean, 6– 103m. The adult specimens were well described in Stebbing (1910), Băcescu (1961), Day, (1978), Petrescu (1998), and Corbera (1994). Iphinoe suluensis sp. nov. is distinguished from I. crassipes by (1) having 4–8 spiniform setae present on the outer margin of the uropod exopod (not present in I. crassipes), (2) the median-dorsal ridge of the carapace obsolete (discernible, with small teeth in I. crassipes), (3) the antenna 1 main flagellum article 2 with 4 stiff simple setae (1–2 simple setae in I. crassipes).</p><p>Iphinoe suluensis is also similar to Iphinoe pokoui Le Loeuff &amp; Intes, 1972 from Cote D’Ivoire, western coast of Africa, 20 m. The former species is distinguished from the latter by (1) the carapace has longitudinal ridges for the entire length (anterior portion in I. pokoui), (2) the antennal notch is triangular (round, widely open in I. pokoui), (3) the uropod endopod is longer than the exopod (subequal or slightly shorter than exopod in I. pokoui), and (4) the uropod exopod article 2 is much longer than article 1 (subequal in length to article 1 in I. pokoui).</p></div>	https://treatment.plazi.org/id/677387C4F34AFFC7D6E9FF67FDBAFC87	Public Domain	No known copyright restrictions apply.
