Genus Adeliella Nicholls, 1938 View in CoL
Adeliella, Nicholls, 1938: 12 View in CoL . – J.L. Barnard 1969: 320. – De Broyer 1975: 73. – J.L. Barnard and Karaman 1991: 457.
Emended diagnosis (new characters in bold). Antennae very short, subequal to or little longer than head length. Lateral cephalic lobe rounded. Lower lip inner lobe poorly developed or absent. Mandible with well-developed and triturative molar. Maxilla 1 inner plate naked or with a very short apical seta; outer plate bearing 5–7 robust setae; palp 2-articulate, article 2 lanceolate with apico-lateral robust setae. Maxilla 2 inner and outer plate pointed distally and poorly setose; inner plate 1/2 or subequal to outer plate. Maxilliped poorly setose; dactylus short, 1/2 or less of article 3 length. Coxa 1 short, suboval, anterior margin convex. Gnathopod 1 subchelate, carpus triangular. Gnathopod 2 mitten-shaped, carpus slender and long; propodus palm very short, parachelate; dactylus much longer than palm. Uropods rami lancelate. Uropod 2 inner ramus without notch. Uropod 3 outer ramus 2-articulate, inner ramus shorter than outer ramus article 1. Telson almost as long as wide, notched to ~50% cleft (modified from De Broyer 1975; J.L. Barnard and Karaman 1991).

Genus remarks
The diagnosis of the genus and family is here expanded to accommodate the new species described below. Important and new characters were observed in the literature and in our new species that might be useful for generic assignments, such as: very short antennae, subequal to or little longer than head length; lower lip inner lobe poorly developed or absent; maxilla 1 inner plate naked or with a short apical seta, outer plate with 5–7 robust setae; gnathopod 2 palm very short and parachelate; and rami of uropods lanceolate.
