Lacking appendages, a pair of lobes and single dorsal lobe</p><p>Paratype female ICML-EMU-12989 (Fig. 2B, 3E, 5G) Body length 2.40 mm. Similar to the male, except for the following characteristics: presence of oostegites on pereonite 3 and 4, setose on pereonite 3 (Fig. 2B); pereonite 3 lacking a mediolateral projection. Abdomen with a pair of lateral lobes with setae at middle and with single dorsal lobe (Fig. 5G).</p><p>Habitat: The specimens were collected on two samples of the marine sponge T. helium, at 24 and 30 m depth in association to the caprellids Aciconula acanthosoma and L. isabelensis .</p><p>Remarks. Considering the 15 reported species (including the present material) from the Liropus recorded worldwide, L. alarconi n. sp. is close to L. japonicus Mori, 1995 from the North-west Pacific and L. gurui GuerraGarcía et al. 2015 from the Caribbean Sea. All three species have a two-articulated flagellum on antenna 1, peduncular article 1 of antenna 1 with lateral bulge on distal end and peduncular articles 2–3 swollen distally; head without projections; pereonites 2–4 without anterolateral projections; pereopods 3 and 4 one-articulate and pereopod 5 two-articulate. Gnathopod 2 of L. japonicus, presents an irregular process at the base, its propodus has a medial deep triangular cleft with roughly serrate margins distally (Mori, 1995), while in L. alarconi n. sp., it is smooth and lacks the cleft in contrast to L. gurui . However, L. alarconi n. sp. can be distinguished easily from L. japonicus and L. gurui in pereonites 2–5 each with one dorsodistal projection (pereonite 2, backward projected; pereonites 3–5 downward projected). Liropus gurui has been recorded at depths from 45 to 70 m collected from the mesophotic coral ecosystems in Puerto Rico, Caribbean Sea (Guerra-García et al. 2018); while L. japonicus has been collected from the dead coral masses covered with algae and sessile animals (Mori, 1995). Liropus alarconi n. sp. has been recorded at 25 to 30 m depth associated to the tropical marine sponge T. helium near to coralline patches similar to L. isabelensis which has been recorded in a coralline environment in Mexican Pacific coast (Alarcón-Ortega et al. 2017b).</p></div>	https://treatment.plazi.org/id/03CC87E7FFC71C6B519AFE6174B2699E	Public Domain	No known copyright restrictions apply.
