Family PARAPAGURIDAE Smith, 1882


This family of deep water hermit crabs was resurrected from synonymy with the Paguridae by de Saint Laurent (1972). Since then the Australian fauna has been well studied by Lemaitre (1996, 1999). Parapagurids are found in all oceans, and typically live in continental shelf and slope depths ranging from about 200 to 5000 metres, although there are some records from as shallow as 50 metres.



Carapace and body paguroid in form ('hermit crabs'). Cephalothoracic shield not narrowing posteriorly. Epistome usually with two median spines: labral spine always present and placed immediately in front of labrum; interantennular spine (sometimes lacking) before insertion of antennal peduncle. First maxilliped with basipodite enlarged and fringed with setae on outer margin; exopod without flagellum. Coxae of third maxillipeds widely separated, sternite armed with pair of spinous tubercles; distal region of ischium clearly wider than base of merus; ischium with well-developed, regular crista dentata; without accessory tooth. Chelipeds very unequal (except in Probeebei), right much longer and stronger. Pereiopods 2 and 3 typically long and slender, unarmed; P4 subchelate, P5 chelate. Abdomen asymmetrical, membranous or partly calcified; abdominal tergites entire, not arranged in paired plates on each segment. Telson entire, sometimes with weak lateral indentations. Males with genital organs paired, genital pores opening on coxae of P5; pleopods paired, present on first two abdominal segments (most Parapagurus and Tylaspis species), on first (Probeebei) or second segment (Typhlopagurus), sometimes totally absent; pleopods 3–5 unpaired, left, biramous, with short exopod. Female with genital organs unpaired, right ovary atrophied such that only single genital pore on coxa of left P3; all pleopods left, unpaired, or second pleopods asymmetrically paired, and 3–5 unpaired. Eleven pairs of branchiae, 10 arthrobranchs from maxilliped 3 to pereiopod 4, and pleurobranch on P4; sometimes a pleurobranch on P5; branchial lamellae bilobed, or entire, or variously intermediate. (After de Saint Laurent, 1972).
