Species Fosshagenia suarezi - Plate 1 of morphological figuresissued from : A. Fosshagen & T.M. Iliffe in Sarsia, 2004, 89. [p.348, Fig.1].
Female (from Grand Bahama): A-B, habitus (dorsal and lateral, respectively); C, A1; D, A2.

Nota: Rostrum blunt with no filaments. Head and 1st thoracic segment separate, 4th and 5th separate. Urosome 4-segmented, about half length of prosome. Caudal rami with 3 terminal setae; middle seta of left ramus enlarged and twice the length of adjacent setae; medially on inner margin left ramus bears thin 4th seta directed backwards and in corresponding place on right ramus seta directed ventrally. A1 23-segmented. Exopod of A2 7-segmented with 9 setae along inner margin and 3 terminal ones; 1st and 2nd segments double, each bearing 2 setae.


Species Fosshagenia suarezi - Plate 2 of morphological figuresissued from : A. Fosshagen & T.M. Iliffe in Sarsia, 2004, 89. [p.349, Fig.2].
Female: A, Md; B, Mx1; C, Mx2; D, Mxp.

Nota: Md with simple and short teeth on gnathobase; basis with 4 inner setae; endopod 2-segmented; exopod 3-segmented (indistinctly in middle part) with 6 setae in total. Mx1 with 11 setae on praecoxal arthrite; coxal endite, 1st and 2nd endites with 3, 4 and 4 setae, respectively; endopod fused to basis, 3rd segment expressed, segments 1-3 with 2, 2 and 5 setae, respectively; exopod bearing 11 setae. Mx2 with well-developed lobes carrying thin and plumiose setae; 1st praecoxal lobe with 5 setae; 2nd praecoxal lobe,1st and coxal lobes and basal endite with 3, 3, 3 and 4 setae, respectively; endopod indistinctly segmented with 8 setae. Mxp with reduced number of setae on syncoxa; endopod 6-segmented with 1st segment partially fused with 2nd segment and bearing 2 setae, 2nd to 6th segments carrying 3, 2, 3 and 4 setae, respectively; 5th segment with relatively long outer seta.


Species Fosshagenia suarezi - Plate 3 of morphological figuresissued from : A. Fosshagen & T.M. Iliffe in Sarsia, 2004, 89. [p.350, Fig.3].
Female: A-E, P1 to P5.


Species Fosshagenia suarezi - Plate 4 of morphological figuresissued from : A. Fosshagen & T.M. Iliffe in Sarsia, 2004, 89. [p.351, Fig.4].
Male: A, urosome (dorsal); B, right A1; C, P5 (posterior view; D, right P5, lateral view from inner side (coxa omitted); E, left P5, lateral view from inner side (coxa omitted).

Nota: Urosome 5-segmented. caudal rami as in female. Right A1 18-segmented; weak proximal geniculation between segments 10 and 11 (representing ancestral segments XIII-XV and XVI-XVII, respectively) stronger distal geniculation between segments 14 and 15; left A1 segmented as in female but both antennulae differ from female in bearing 1 aesthetasc on segments 4 (VI) and 6 (VIII) and 2 on segment 8 (trithek on X).
