GenusDoroteaCorbari, Frutos & Sorbe, 2019 Type species. Dorotea papuana Corbari, Frutos & Sorbe, 2019 (original designation). Included species. Dorotea aberrantis (Bellan-Santini & Ledoyer, 1987); D. papuana Corbari, Frutos & Sorbe, 2019; Dorotea elizae sp. nov. Diagnosis. (updated after Corbari et al. 2019). Body not strongly compressed, dorsally smooth. Rostrum short. Head lateral cephalic lobe weakly produced. Eyes lacking. Antennae medium size. Antenna 1 probably slightly longer than antenna 2, peduncular article 1 subequal to article 2, accessory flagellum uni-articulated, linear. Antenna 2, peduncular article 4 broader than article 5, flagellum not shortened. Upper lip evenly rounded distally. Lower lip, inner lobes weak. Mandible, incisor with long incurved cutting edge, poorly dentate or smooth; lacinia mobilis five-dentate; setal row with six or seven setae; palp, article 3 longer than article 2, slightly falciform, tapering distally; article 2 broader than article 3. Maxilla 1, inner plate with 1–3 subapical setae; outer plate with ten or 11 apical stout setae; palp slender, distal article longest. Maxilla 2, inner plate broader and shorter than outer plate. Maxilliped palp, articles ordinary; outer plate large; inner plate with three apical teeth. Coxae 1–4 regular, medium; coxa 1 broadly rounding, not produced; coxa 4 slightly excavate posteriorly. Coxae 5 and 6 bilobate. Gnathopods 1 and 2 subsimilar, both strongly subchelate; carpal lobes broad; propodus large, posterior margin short, palm oblique, margin spinose. Pereopods 3 and 4 slender, merus slightly longer than carpus, dactylus simple, stout and medium length. Pereopods 5–7 homopodous, subequal in form and size, not greatly elongate; bases broad; dactylus simple, stout and medium length. Epimera 1–3 regular, not serrate on posterior margin. Uropods 1 and 2 rami lanceolate, outer ramus shorter than inner ramus. Uropod 3 rami broadly lanceolate, outer ramus shorter than inner ramus. Telson elongate, lobate, weakly cleft. Brood plates on pereopods 2–5. Coxal gills on pereopods 2–7. The genus Dorotea was created for Dorotea papuana Corbari, Frutos & Sorbe, 2019 and also includes D. aberrantis (Bellan-Santini & Ledoyer, 1987) previously assigned to Eusiroides (Bellan-Santini and Ledoyer 1987). Our individual matches the generic diagnosis in most characters. However, seven characters appear to vary between species assigned to this genus (see Table 4). Each of the species of Dorotea is known only from a unique individual of a different sex (D. papuana from the female, for the other two species only males are known), so there is no possibility to infer the intraspecific variation. With the exception of the shape of the upper lip these characters need to be treated as species specific ones. There is a large difference in shape of the upper lip between our specimen and the other two Dorotea species described; however, due to the three-dimensional nature of this appendage the differences in observed shape may be associated with positioning during slide preparation. The lack of more individuals of any of the species prevents from decision how stable is this character; this is why the shape of the upper lip was left unchanged in the generic diagnosis.
