Eurytemora richingsi Heron & Damkaer, 1976 (F,M) | |
| | | | | | | Ref.: | | | Heron & Damkaer, 1976 (p.128, Descr.F,M, figs.F,M); Kos, 2016 (p.91, figs. 49, figs.F,M, Rem.) |  issued from : G.A. Heron & D.D. Damkaer in Proc. Biol. Soc. Wash., 1976, 89 (8). [p.130, Figs.1-5]. Female (from 83°14', 153°48'-154°02'W): 1, habitus (left lateral); 2, posterior of prosome and urosome (dorsal); 3, genital segment (ventral); 4, right Md; 5, P1 (anterior). Scale bars: 0.10 mm.; a : figs. 1, 2; b: figs. 3, 5; c: fig. 4. Nota : - A1 25-segmented, segments 8-9 and 24-25 with incomplete sutures. - Md with wide gap on blade separating outer denticle, hyaline setules between anda t bases of some denticles and anterior edge ; - A2, Mx1, Mx2 , and Mxp with setation and segmentation typical for the genus. - P1 atypical for the genus : endopod with 8 instead of 6 setae, and incipient segmentation on anterior surface, anterodistal cluster of setules on 1st basipod. - Caudal rami length about equal to that of anal segment, inner marginal hairs.

 issued from : G.A. Heron & D.D. Damkaer in Proc. Biol. Soc. Wash., 1976, 89 (8). [p.132, Figs.6-10]. Female: 6, P2 (anterior); 7, P3 (anterior); 8, P4 (anterior); 9, P5 (anterior); 10, left P5 (posterior). Scale bars: b (figs. 6-9); c (fig. 10). Nota : P2 to P4 with setation and segmentation typical for the genus P5 with outer sclerotized margins, conspicuous at posterior articulation of exopod ; 1st exopod with 2 finely barbe douter spines ; robust inner spinous process with anterior and posterior row of short spinules ; exopodal segment 2 small, oval, with 2 outer and 1 terminal finely barbed, sinuate spines, 2 delicate setules on inner margin.

 issued from : G.A. Heron & D.D. Damkaer in Proc. Biol. Soc. Wash., 1976, 89 (8). [p.134, Figs.11-17]. Male: 11, habitus (right lateral); 12, urosome (dorsal); 13, right A1 (segments 4-12, spine solid); 14, right A1 (segment 16); 15, P5 (anterior); 16, P5 (posterior); 17, left P5 (2nd exopodal segment, anterior). Scale bars: a (figs. 11, 12); b (figs.15, 16); c (figs.17); d (figs 13, 14). d = 0.10mm. Nota : - A2, Md, Mx1, Mx2, and Mxp like those of female. - P1 to P4 similar to those of female. - P5 with 1st basal segments fused left to right ; left ramus 3-segmented, exopodal segment 2 with distinctive mitten shape with 2 outer spines and 2 spines on the articulated thumb, dense clusters of setules on distal surfaces ; right ramus 4-segmented. Several other Eurytemora species have bulbous projections on the left terminal exopod, but none is described as being articulate.
