Fig. 13 j

Danielopolina exuma Kornicker & Iliffe 1998: 70 : figs. 50–60.–2000: 86.

Holotype. USNM 194305 , undissected adult female in alcohol.

Type locality. Norman’s Pond Cave, Norman’s Pond Cay, Lee Stocking Island , Exuma Cays, Great Bahama Bank .

Material. Norman’s Pond Cave , Sta. 94-016: USNM 194419 , partly dissected adult female paratype on slide and in alcohol. Basil Minn’s Blue Hole, Sta 00-001, USNM 1021378 , undissected adult male in alcohol; Sta 00-004, USNM 1021379 , undissected adult female in alcohol, with large unextruded eggs .

Distribution. Great Bahama Bank: Lee Stocking Island, Exuma Cays: Norman’s Pond Cay, (Norman’s Pond Cave); Great Guana Cay (Oven Rock Cave); Great Exuma Island (Basil Minn’s Blue Hole).

Remarks. Some appendages of a female paratype (USNM 194419) were examined to estimate their variability.

Supplementary description of adult female ( Fig. 13 j ). Carapace size (mm): USNM 1021379, length with anterior process 0.60, length excluding anterior process 0.54, height 0.46.

First antenna: USNM 194419, 1st and 2nd segments forming right angle ( Fig. 13 j ). Same as 1st antenna of adult female illustrated by Kornicker & Iliffe (1998: fig. 51 d,e).

Second antenna: USNM 194419, except for minute lateral spine-like bristle near dorsal margin of 2nd segment being barely visible using oil immersion objective, endopod similar to those of adult female illustrated by Kornicker & Iliffe (1998: fig. 51 g,h)

Mandible: USNM 194419, endite of basis with 4 lateral bristles (2 long, 2 short) on left limb and 5 on right limb (3 long, 2 short). (Right limb differs from basis of both left and right mandibles of adult female illustrated by Kornicker & Iliffe (1998: fig. 51 j,k) in having 3 instead of 2 long lateral bristles.)

Variability. Second antenna: 2nd endopod segment with minute lateral spine-like bristle near dorsal margin (indistinct on some specimens). Mandible: basis endite with 2 or 3 long lateral bristles.

Supplementary description of adult male. Carapace size (mm): USNM 1021378, length without anterior process 0.48, height 0.44.

Remarks. The species is reported for the first time in Basil Minn’s Blue Hole.
