Zool. Inst. RAN, St. Petersburg, 1996, 268. [p.109, Fig.82]. Female. (specimen of Kuril Trench). P.md: mandibular palp. Nota: Despite minor differences in setation of Mxp, and length of 1st outer spine on exopod of P1 this form is attribuated to C. subaequalis

issued from : G.D. Grice & K. Hulsemann in J. Zool., 1965, 146. [p.234, Fig.10]. Female (29°57'N, 22°58'W): a, habitus (lateral right side); b, A2; c, Md; d, Mx1 (spines on 1st lobe omitted); e, Mx2; f, distal end of Mxp; g, proximal segment of Mxp; h, P1; i, P2; j, detail of tooth structure on terminal spine of P2; k, P3; l, P4. Nota: Head and 1st thoracic segment separate, 4th and 5th fused. A1 reaches end of prosome. Endopod and exopod o fA2 subequal Mx1: 2nd and 3rd inner lobes with 1 and 4 setae, respectively; endopod with 7 setae; exopod with 4 setae. Mx2 with distal 3 lobes each bearing a heavily thickened seta, all of equal length. Mxp with elongate setae on endopodal segments. Exopods of P2-P4 3-segmented with 1st and 2nd segments incompletely separated.

Chiridiella subaequalis female: 1 - Mx2 with 5 endites. 2 - Mx2 not strongly modified in comparison with typical; setation first-fifth endites nearly of the same size, without pincers-like spines. 3 - Endopod of P1 without external lobe. 4 - Exopod of P1 with 2 external spines. Mx1 second and third internal lobes with 1 and 4 setae respectively; endopod with 7 setae; exopod with 4 setae.
