Body elongate, cylindrical, slightly depressed dorsoventrally and slightly tapering distally. No distinct separation between prosome and urosome. Cephalotorax approximately quadrangular, larger than somites, longer than the following two somites, with sensilla and several dorsal pores. Dorsal pores present also on the remaining somites. Genital complex of female: genital field small, transversally oval, ventrally at half length of the double genital somite which lacks dorsal suture; P6 reduced to two small arched chitinous plates, apparently not fused; genital pore near the distal margin of the genital field, below the P6. Penultimate somite with well-developed quadrilobate pseudoperculum. Caudal rami approximately cylindrical, tapering distally in lateral view, apparently with six setae. Seta I missing (or not discernible), seta III and VI enlarged and pointed, unipinnate in the distal third on the outer (seta III) or inner (seta VI) margin. Distal setae (IV and V) variable in shape, peculiarly transformed in short fusiform structures in some specimens; seta VII dorsally inserted at 2/3 of the ramus length, biarticulate at base. Rostrum small, triangular, fused to cephalothorax, with two sensilla. Antennule 8-segmented in female, with large aesthetasc on segment four and small easthetasc on segment eight. Antennule 7-segmented in male, short, subchirocer, aesthetasc on segments V and VII. Antenna 4-segmented; coxa and basis without ornamentation, enp-1 with strong pinnate abexopodal seta, enp-2 armed with eight elements; exopod 1-segmented with two lateral setae and one or two distal ones, the longest one pinnate. Mandible with uniramous and 2-segmented palp comprising basis, 1-segmented endopod with four setae or three setae and one spine. Coxal gnathobase long, with dorsal seta; cutting edge with a row of thin and pointed teeth along the distal margin, with a stronger tooth at the inner and outer corner. Maxillula: praecoxal arthrite with strong lateral seta and 5-6 distal spiniform setae; coxa with one or two distal setae, basis with one or two to three apical setae; exopod and endopod missing. Maxilla large, with reduced chaetotaxy; syncoxa with three endites: proximal and median ones with one seta, distal one with two or three pinnate setae; basis produced into strong claw; endopod fused with basipodite, carrying four setae, one or two of which are claw-like. Maxilliped: subchelate, syncoxa bare; basis elongate and bare; endopod 1- or 2-segmented. P1: coxa large and bare, basis without outer basal seta, with strong inner seta; rami 2-segmented, endopod slightly longer than exopod, or of about equal length; exp-1 with long pinnate outer seta, exp-2 with four setae; enp-2 with two geniculate apical setae. P2-P4 laterally displaced but coxa and basis not fused and not markedly produced laterally; basis with outer seta. P2 basis with inner setular row in females; exopods 3-segmented, with two spiniform setae on distal segment; endopods absent. P5 very reduced in both sexes, partly incorporated in somite. In females, baseoendopod represented by a lobe with a lateral seta, exopod reduced to a minute subrectangular lobe with two bare and one pinnate setae or exopod reduced to a lobe with one seta. In males, baseoendopodal lobe with one seta, exopodal lobe with two setae or reduced to a small lobe without armature. P

has not been redescribed according to modern standards, and only the females are known. Nonetheless, the mandibular palp is uniramous, being represented by the basis and the endopod, and the structure of the maxilla (endites with reduced armature, basis prolonged into a claw, a second claw originates from the partially fused endopod) and maxilliped (with 1-segmented endopod) are characters which indicate a degree of affinity with the new genus. The morphology of the maxilla, pseudoperculum and P5 are unknown for this species, the caudal rami differ in shape and ornamentation and the body size of this species is very large (700 μm).
