AUSTRALIAN OPILIONES 73 
spinous projection at each outer margin of the chelicerae where 
they articulate with a round process on the outer proximal surface 
of each chelicerae (Fig. 25). Areas I-IV not distinguished by 
transverse grooves but each with a transverse row of small 
granules, restricted to the median surface on areas I-III, but 
extending to the lateral margins of areas IV-V. Free tergites and 
the sternites also with a single transverse row of small granules. 
Genital operculum smooth. Sternum as in Fig. 28. 
Chelicerae. Relatively long, equal to the length of the body. 
Basal segment with a rounded boss on the outer proximal sur- 
face (Fig. 25), otherwise smooth. Second segment with a setose 
tubercle on the inner proximo-dorsal surface, followed by several 
smaller setose tubercles. 
Pedipalps. Inner proximo-ventral surface of coxae produced 
anteriorly as a pair of long digitate processes (Fig. 28). Remain- 
ing segments of pedipalp as in Figs. 29, 30. Trochanter with 
a strong medio-dorsal spine, otherwise smooth. Femur with a 
ventral row of six spines, the third and fifth being small, the 
proximal spine expanded distally and broadly clavate where it fits 
into the enlarged spine on the inner proximo-lateral margin of 
coxa I. Patella smooth except for a small sub-distal spine on the 
inner surface. Tibia rounded, not concave, below; armed with one 
small and three strong spines along the outer ventro-lateral mar- 
gin and two small proximal and a large distal spine on the inner 
ventro-lateral margin. Tarsus rounded below, with three outer 
and three inner ventro-lateral spines. Tarsal claw strong. 
Legs. Coxae below as in Fig. 28. Coxae I with a large cup- 
shaped process on the prodistal margin in which the proximo- 
ventral process of the femur of the pedipalp rests; coxa II with 
a large, blunt, curved spine on the retrodistal surface, and coxa 
IV with a smaller unevenly bifurcate spine on the prodistal 
surface. Trochanter to metatarsus of all legs sparsely granulate. 
Caleaneus small but distinct, not notched. Tarsal formula 4, 10-11, 
4, 4. Distotarsus of leg 1 two-segmented, leg II four-segmented. 
Tarsal claw of legs ПІ and IV with small sideclaws.
