摘要：
A new species of Dulichiella Stout, 1912 is described in this paper. The genus Dulichiella comprises 19 species, known from tropical and warm temperate seas worldwide. Material examined was manually collected associated to infralittoral sponges, ascidians, and algae, at Urca beach rocky shore, Guanabara Bay, Rio de Janeiro, Brazil. The new species can be characterised by the following: antenna 1 peduncle articles ratio 1.0:1.2:0.2, article 1 ventral margin with two robust setae; mandible palp articles ratio 1.0:2.4:2.6; gnathopod 1, coxa anteroventral corner unproduced, palm concave; gnathopod 2 distolateral crown with four spines; epimeral plate 1 posteroventral corner subacute; and pleosome/urosome spine formula 7-7-7-5-4-2. An identification key to world species of the genus is provided.
