Diagnosis of adult male
Total body length, measured from base of rostrum to end of caudal rami, 350 μm. Body length/urosome 7.7. Hyaline frills on all somites smooth. Cephalothorax somewhat rectangular, with vague, spherical integumental window. Urosomites 3–5 each with somewhat elliptical, dorsal integumental window. Anal somite ( Figure 14A View Figure 14 ) ornamented with two pairs of crescentic rows of particularly large but unequal spinules on ventral surface. Caudal rami four times as long as wide and 0.8 times as long as anal somite; dorsal seta inserted at four fifths of ramus length opposite to lateral group of setae. Aesthetasc on fifth antennular segment large, club-shaped. Leg 1 basis ( Figure 14B View Figure 14 ) with digitiform chitinous structure near proximal inner corner in addition to usual outer seta; exopod shorter than endopod; second and third exopodal segments sharply bent inwards. Leg 2 endopod ( Figure 14C View Figure 14 ) spatulate, unornamented, bearing an apical bipinnate, inwardly bent claw-like seta. Leg 3 ( Figure 14D View Figure 14 ) arc-like, exopod one-segmented, ornamented with large spinules on outer distal margin and tiny hyaline lobe on inner distal margin; apophysis conical, shorter than spiniform, outcurved thumb and somewhat bulging at proximal outer angle. Endopod short, one-segmented, digitiform and tipped with simple seta. Leg 4 ( Figure 14E View Figure 14 ) basis with a row of five large, imbricate spinules at insertion of endopod; spinules increasing in size from internal to external; endopod one-segmented, flask-shaped, 0.8 times as long as first exopodal segment, with bulbous proximal half and narrow, incurved, horn-like distal region, and ornamented with three slender spinules at about mid-length of outer margin; exopodal segments of legs 2 and 4 ornamented with a row of spinules each outer margin. Leg 5 ( Figure 14F View Figure 14 ) without intercoxal sclerite; large, conical plate-like structure, ending in short spinous process, reaching almost midlength of next somite; armature consisting of uniarticulate outer seta followed by one short spiniform seta and two moderately long setae; inner margin ornamented with five large spinules around the middle. Leg 6 smooth, unarmed, forming simple operculum covering gonopore, fused with somite; in lateral view ( Figure 14F View Figure 14 ) appearing a conical protrusion, reaching posterior margin of same somite.
