The most species-rich genus of the subfamily Sarsiellinae, with c-, f-, and g-bristles not claw-like on the first limb and the d-bristle present. These ostracods have an anterior incisure and the posterior infold bears a row of spinous bristles. In females, the seventh limb bears paired, terminal teeth. Each lamella of the furca with five claws; claw 1 fused to the lamella, claws 2 – 5 separated from lamella by suture. Claws decrease in length posteriorly along lamella. For a key to Sarsiellidae, see Kornicker (1986). Composition.

039E87F6FFF8FFC660E315B6FE85FCEB.taxon	diagnosis	Diagnosis. A Eusarsiella species, with a small, rounded caudal process and minute anterior incisure on the inner carapace margin. Shell ornamented with many fossae. The carapace of E. bryanjuarezi resembles both E. dominicana (known from the Dominican Republic) and E. absens (known from Bermuda). E. bryanjuarezi is nearly circular in lateral view, whereas both E. dominicana and E. absens are distinctly oval. The posterior margin of E. bryanjuarezi is flat in lateral view where that of E. absens is concave. E. bryanjuarezi and E. absens have different carapace sculptures: the former has a single rib extending from above the central adductor muscle attachments to the posterodorsal bulge, whereas the latter has an additional horizontal rib below the central adductor muscle attachments (see Kornicker 1986). E. absens in Kornicker 1986 (Figure 25) also has three to four weakly developed radiating ribs on the anterior portion of the carapace (Kornicker 1981 a as Sarsiella absens), whereas E. bryanjuarezi has none. E. bryanjuarezi (1.03 – 1.05 mm) adult females are of a similar size to E. dominicana (1.08 mm) but E. absens (1.17 – 1.22 mm) are around 10 % larger (Kornicker 1986). Internal diagnostic features of the three species are as follows: On the first limb, the third and fourth fused podomeres have differing number of bristles. E. bryanjuarezi has a total of six bristles and one spine (see below), E. dominicana has a total of four bristles, and E. absens has a total of three (Kornicker 1986). Finally, adult female E. bryanjuarezi have about 10 ommatidia while E. dominicana have four (Kornicker 1986) and E. absens have five (Kornicker 1981 a).	en	Churchill, Celia K.

039E87F6FFFBFFCB60E314F6FBA4FEF8.taxon	diagnosis	Diagnosis. A Eusarsiella species, with a prominent, triangular caudal process and minute anterior incisure. Shell ornamented with many fossae and posterior processes bearing short bristles and one long bristle. Posterior processes decrease in size dorsally. Valve margin extremely hirsute. Short, anterior processes along the perimeter of the valve, bearing minute bristles. The carapace of Eusarsiella eli closely resembles the Caribbean E. paniculata, especially in the placement of processes and bristles ornamenting the carapace. The caudal process of E. eli is pointed postero-ventrally, whereas that of E. paniculata points posteriorly. The two species also differ in adult female size; E. paniculata (1.24 – 1.32 mm length and 0.95 – 1.03 mm height; Kornicker 1986) is relatively longer than E. eli (1.15 mm length and 1.11 mm height). Internal diagostic characters between the two species are as follows: The second podomere of the first limb is bare in E. eli, but bears a dorsal bristle in E. paniculata (Kornicker 1986). The endopodite of the second limb is monomeric in E. eli but dimeric in E. paniculata. Finally, the exopodite of the fourth limb has three bristles in E. eli, whereas E. paniculata has two.	en	Churchill, Celia K. C., Ellis, Emily A., Pique, Alannah E., Oakley, Todd H.
