Type species. Grandidierella mahafalensis Coutière, 1904, monotypy.
Diagnosis [emended from Ariyama & Taru (2017)]. Body subcylindrical, slightly depressed laterally, smooth. Head, rostrum short, ocular lobes short; eyes small to medium. Urosomites free. Antenna 1 elongate, slender, peduncular article 3 much shorter than article 1, accessory flagellum 1–2 articulate; antenna 2 stouter than antenna 1, flagellum shorter than peduncular article 5. Mandible, palp with 3 articles, article 3 clavate or rectolinear. Maxilla 1 with vestigial inner plate; outer plate with ca. 10 robust setae; palp biarticulate, with several robust setae at tip. Maxilla 2, inner plate usually with mediofacial row of setae. Maxilliped, inner plate with several robust setae distally; outer plate not reaching apex of palp article 2, with many marginal robust setae; palp consisting of 4 articles, article 4 with short robust seta (nail). Coxae small, relatively shallow, slightly or not overlapping; gills present on coxae 2–6; oostegites of female broad, present on coxae 2–5. Male gnathopod 1 greatly enlarged, carpochelate; carpus dilated, propodus short, dactylus stout. Female gnathopod 1 smaller than that of male, subchelate, palm oblique. Gnathopod 2 of both sexes smaller than gnathopod 1, subchelate; carpus longer than or almost same length as propodus, palm transverse. Pereopods 3 and 4 similar to each other, slender; bases elongate. Pereopods 5–7 similar to each other, pereopod 5 much shorter than pereopods 6 and 7; basis of pereopod 7 heavily setose posteriorly. Uropods 1 and 2 biramous, spinous, uropod 1 longer than uropod 2, peduncles longer than both rami; uropod 3 uniramous, peduncle usually shorter than single ramus, dilated medially. Telson entire, short, fleshy, with pair of hooked apical cusps.
Remarks. Recently, Myers & Desiderato (2019) established a new genus, Propejanice Myers & Desiderato, 2019, having a carpochelate male gnathopod 1 and a setose male gnathopod 2 with a divergent merus. Although they stated Propejanice is close to the genus Janice Griffiths, 1973, this genus should be synonymized with the genus Grandidierella, because three Grandidierella species (G. exilis Myers, 1981; G. gilesi Chilton, 1921; and G. melakaensis Azman & Othman, 2012) have such a gnathopod 2. Following this synonymization, Propejanice lagamarensis Myers & Desiderato, 2019 is changed to Grandidierella lagamarensis (Myers & Desiderato, 2019) comb. nov.
