Description Transformed adult female. Body (Fig. 1A) comprising cephalothorax, neck and trunk incorporating minute abdomen and bearing large paired posterior processes. Measurements of holotype female: total length measured from frontal margin of cephalothorax to posterior margin of anal prominence (excluding posterior processes) 24.5 mm; cephalothorax length 1.6 mm, width 3.9 mm; neck length about 13.8 mm, trunk length about 9.1 mm [neck ? trunk combined length 22.9 mm], maximum trunk width 2.1 mm; posterior processes length 4.9 mm, width 1.1 mm; egg sac length 14.4 mm. Mean total body length of intact paratypes 25.1 mm, range 22.3 to 27.3 mm (n = 10).
Neck slender, cylindrical with smooth margin; expanded anteriorly at junction with cephalothorax; expanding gradually posteriorly to merge with trunk. Neck always longer than trunk, mean 1.48 times, with a range of 1.02 to 1.90 times longer (n = 11). Trunk about 4.3 times longer than wide, slightly compressed dorsoventrally and increasing in width towards maximum at posterior end; bearing paired lateral swellings near posterior end (Fig. 2D,E). Abdomen (Fig. 2F) incorporated into trunk. Trunk bearing paired posterior processes ventrally; each process cylindrical, blunt tipped, and ranging from 4.5 to 6.9 times longer than wide, with mean of 5.6 times (n = 13). Egg sacs multiseriate, originating from dorsally located oviduct openings near posterior margin of trunk; typically about twice as long as posterior processes, ranging from 1.8 to 2.9 times longer (n = 8).
Cephalothorax bulbous bearing pair of antennary swellings anteriorly on ventral surface (Fig. 1B, as; Fig. 2B, C); frontal margin of antennary swellings typically just visible in dorsal view (Fig. 1A, 2A). Paired posterior swellings on ventral surface of cephalothorax clearly visible in dorsal view (Fig. 1A). Two additional paired swellings present on ventral surface of cephalothorax, between antennary and posterior swellings (Fig. 1B, ps): smaller maxillary swellings (Fig. 1B, ms) and larger ventrolateral swellings (Fig. 1B, vls). Paired maxillary and ventrolateral swellings confluent at base and separated, along ventral midline, by narrow raised central ridge (Fig. 1B, cr).
Antennule cylindrical, indistinctly segmented; setation not observed. Antenna (Fig. 1C) biramous; protopodal part unarmed; exopod unsegmented, bulbous, shorter than endopod; armed with inner and outer setae subapically; ornamented with minute denticles on rounded apex; endopod 2-segmented, proximal segment ornamented with spinules distally; distal margin of terminal segment bearing robust outer hook, 2 stout naked setae, and 1 minute seta; inner extremity of margin slightly inflated and ornamented with minute denticles. Mouth tube not observed clearly. Mandible (Fig. 1D) stylet-like, forming slender blade with 9 marginal teeth increasing in size towards tip. Maxillule (Fig. 1E) slender with 1 small and 2 large setae around apex and 2 small setae on proximally located outer lobe. Maxilla (Fig. 1B, mx) comprising small digitiform process carried posteriorly on maxillary swelling. Maxillipeds located posterior to oral region and anterior to maxillary swellings; subchelate, each with broad protopodal corpus expanded into strongly denticulate myxal process opposing tip of subchela; subchela armed with blunt-tipped seta about midway along inner margin (Fig. 1F).
