Parabradya Lang, 1944 grad. nov. Diagnosis (autapomorphies in italics): Body length of female > 1200 μ m . Exopod of antenna as long as endopod and as strong as enp- 2 . One lateral seta of endopod of mandible situated near the basis . Segments of P 1 –P 4 exopod broad . Exopod of P 5 fused with baseoendopod to form one plate . Groundpattern of Parabradya : Female . Body length > 1200 µm. Nauplius eye absent. Rostrum incompletely fused at base with cephalothorax. Prosome consisting of cephalothorax and 3 free pedigerous somites; first pedigerous somite completely fused to dorsal cephalic shield. Urosome 5 -segmented, comprising somite bearing P 5, genital double-somite, and 3 free abdominal somites; 1 egg-sac, 1 copulatory pore. Anal somite divided longitudinally; anus covered by pseudoperculum. Caudal rami with 7 setae. Antennule 7 -segmented; armature formula: 1, 10, 10 +aes, 1, 3, 4, 7+aes. Antenna composed of coxa, basis, 2 -segmented endopod and 3 -segmented exopod; basis without seta; enp- 1 with 1 seta displaced to the proximal part of the endopod; enp- 2 with 3 subterminal and 7 distal setae; subterminal setation of enp- 2 composed of 3 spine-like setae, one very long; exopod as long as endopod and as strong as enp- 2 with 2, 1, 2 setae, middle segment shortest. Labrum not prominent. Paragnaths fused. Mandible with coxa bearing well-developed gnathobase; cutting edge with 1 seta at proximal and 1 seta at distal corner and distinct teeth; palp comprising basis, endopod and exopod; basis wider than high with 4 setae; endopod 1 -segmented with 3 setae laterally, one situated near the basis, and 7 apical setae; exopod 1 -segmented with 4 lateral and 2 distal setae. Maxillule with praecoxa, coxa, basis, exopod, and endopod; praecoxal arthrite: anterior surface in outer half with 2 neighbouring setae, apically with 3 spines and 3 setae; formula of armature: 2, III, 1, 2, 0; coxa with short coxal endite with 2 setae, epipodite without setae; basis with 3 + 4 setae; endopod 1 -segmented with 6 setae; exopod 1 -segmented with 2 setae. Maxilla 5 -segmented consisting of syncoxa, allobasis, and 3 -segmented endopod; syncoxa with (2 + 2), 2, 3 setae, the 2 proximal endites fused; allobasis very large with reduced endite; accessory armature of allobasis consisting of a spine (I) and 6 setae; claw (I) reduced to spine; endopod 3 -segmented with armature formula: I + 1, I + 1, 4; proximal and middle segment with large spine anteriorly (V + VII). Maxilliped 3 -segmented, comprising syncoxa, basis and 1 -segmented endopod; syncoxa with 2 coxal setae at inner and outer distal corner (10 + 11); basis very large, without setae; endopod 1 -segmented with 1 lateral seta and 3 distal ones. P 1 –P 4 biramous with 3 -segmented rami; praecoxa present; leg pairs joined by intercoxal sclerite; armature formula: P 5 baseoendopod and exopod fused to form 1 plate, left and right P 5 separated; baseoendopod with 1 outer basal seta, endopodal lobe with 2 setae (4 + 5); exopodal lobe with 3 marginal setae and 1 surface seta (9–12). P 6 with 1 seta. Male . Sexual dimorphism in body size, genital segmentation, antennule, P 5 and P 6. Urosome consisting of somite bearing P 5 and 4 abdominal somites; 1 spermatophore. Antennule subchirocer with 7 segments.
