2B and 2E) was divided into two segmented parts: proximal part which had no orna-mentation in the form of scales but the basal podomere (plate) bears a large posterior spine, the second bears a pair of anterior spine with rounded tips, the third bears a pair of median spine, and the last podomere terminates in a hook; proximal part stout, first segment slightly curved, bearing large triangular posterior and anterior spines with rounded tips; second segment with hook-shaped spines bending toward abdomen, slender distal part of antennule bearing anterior blunt knob, extending slightly beyond terminal spine, second segment of distal part half as long as first; terminal segment bearing about five to seven stout apical setae.
Ventral surface of ischipodite of third maxilliped bearing a median longitudinal band of tubercules; inside half of this surface with tufts of rigid setae; distolateral end of podomere rounded, except in V.
The last larval stage, the free-swimming cyprid, settles and attaches to the substratum using the attachment disk on its third antennular podomere (segment) (Lagersson and Hoeg, 2002).
Metatarsus I-II, calcaneus, length in relation to the podomere length, (0) less than half (Maury & Roig-Alsina 1985:figs.
These antennal setae originate relatively proximally on the limb, at the distal end of the third articulating podomere (Fig.
The dorsal cuticle of the distal podomere of the antennule was removed to expose the nerve bundles of the antennule.
Process of second podomere bent laterally and hooked towards third podomere, apex covered with sclerotised spots.
The tibia is again elongate and slender, widening distally to form a disjunct articulation with the next podomere, the basitarsus.
Endobenthic crabs like those mentioned typically have pereiopods with distal podomeres with a sharp edge, mechanically appropriated for an infaunal mode of life.
Measurements for antennomeres and podomeres are representative ratios, given in the following order: scape, pedicel, postpedicel, 1st stylomere, 2nd stylomere; and trochanter + femur, tibia, tarsomeres 1, 2, 3, 4, 5.
The holotype is missing the distal podomeres of leg 1, so it is impossible to tell whether spatulate setae are present, but they seem to occur in NIGP148237, a probable juvenile.
