Introduction
Rectarcturids are recognisable and distinguished from arcturids, antarcturids and austrarcturellids by their straight bodies and reduced setation of pereopods 2–4. The structure of the male pleopod 1 exopod separates rectarcturids from other “straight” families – the groove ends in a distolateral lobe separated from a distomesial lamina by a deep notch (Poore, 2001, 2013). Poore (2013) reviewed the family, described most species and provided a key to genera and species.
Diagnosis
Body more or less cylindrical, without coxal dorsal plates or pleonal epimera, straight, without flexion. Pereopod 1 gnathopod-like; pereopods 2–4 elongated, with pairs of stiff well spaced setae, differentiated from ambulatory pereopods 5–7; with short dactyli, unguis longer and setiform. Uropodal exopod (smaller ramus) tapering (with terminal seta or setae only). Pleopod 1 peduncle more elongate than rami, longer than on other pleopods; exopod of male thickened and with groove on posterior face, ending distolaterally or laterally on simple margin.
