The specimens were sorted from benthic fauna which were collected by washing the sediment obtained by a TV-grab from Station DY115-20VII-S04-TVG04 during the Chinese DY115-20 expedition on R/V Dayangyihao in February 2009. They were preserved in 90% ethanol at the Third Institute of Oceanography, Ministry of Natural Resources, China (Nos. 20VIIS4TVG04.01, 20VIIS4TVG04.02). The specimens were drawn using a Camera Lucida and photographs were taken with an Auto-montage system on a Leica M205 FA stereomicroscope. Measurements were made axially, dorsally for the trunk, laterally for the palp, proboscis and leg and are given in millimetres.
Body length 1.79 mm. Trunk glabrous (Fig.
Proboscis barrel-shaped, 0.7 times as long as trunk, with two dorsal and one ventral triangular processes close to mouth.
Chelifores stout, with one-articled scape; chela atrophied, without fingers.
Palp of nine articles (Fig.
Oviger glabrous (Fig.
Third leg (h-i) slender, longest articles with long setae. First coxa short, with few setae; second coxa 1.5 times as long as first or third coxa, with ventrodistal and dorsal protuberances; femur 2.6 times as long as second coxa, with dorsal and distal long setae, tall cement gland tube dorso-distally; first tibia slightly longer than second tibia and 1.4 times longer than femur, with dorsal, lateral and ventral rows of setae; second tibia with ventral and lateral rows of setae and sparse dorsal setae; tarsus small, subtriangular, with one protuberance dorsally, one spine and few setae ventrally; propodus without heel, sole with seven spines and two distal setae, with two long setae dorsally and some short setae dorsally and distally; main claw slender, gently curved, 0.6 times as long as propodus; auxiliary claws half the length of main claw.
Female unknown.
