description: Lysmata bahia Rhyne & Lin, 2006
Zoea I (Figure 1)
Size (mean ± s.d.): CL = 0.52 ± 0.03 (0.48–0.56) mm; TL = 2.63 ± 0.06 (2.51–2.71) mm.
Carapace (Figure 1A, B): Rostrum slender and long, longer than the antennular peduncle in dorsal view; eyes sessile; anterior dorsomedial papilla present; one pterygostomial spine and six spines along anterior ventral margin.
Antennule (Figure 1A, C): Unsegmented peduncle bearing a small proximal segment with a long plumose seta and a small terminal processs; outer flagellum with one plumose seta, three long aesthetascs and one short aesthetasc that ends in a spoon-shaped membrane on distal margin; microtrichia along the proximal margin of each aesthetascs.
Antenna (Figure 1A, D): Unsegmented peduncle; endopod with one spine and one long plumose seta; exopod (scaphocerite) 5-segmented, with nine plumose setae on inner margin (2, 1, 1, 1, 4), two plumose setae on outer margin and one simple seta on apex (1, 1, 0, 0, 1).
Mandibles (Figure 1E): Asymmetrical; palp absent; incisor and molar processes developed.
Maxillule (Figure 1F): Coxal endite with seven setae (one simple seta, five plumose, and one sparsely plumose); basial endite with five cuspidate setae; unsegmented endopod with two sparsely hardy plumodenticulate setae subterminally and three terminal setae (two sparsely hardy plumodenticulate and one sparsely plumose); microtrichia along the inner side of the coxal and basial endites.
Maxilla (Figure 1G): Coxal endite bilobed with 10 + 4 setae (one simple, three sparsely plumose, nine plumose, and one plumodenticulate); basial endite bilobed with 4 + 4 setae (four sparsely plumose, two papposerrate, and two plumose); unsegmented endopod with nine setae arranged like 3 + 2 + 1 + 3 (five sparsely plumose, one plumose, two sparsely hardy plumodenticulate, and one simple); scaphognathite with five plumose setae; and microtrichia along basial endite and scaphognathite.
First maxilliped (Figure 1H): Coxa with five setae (two sparsely plumose, two plumose, and one sparsely hardy plumose); basis with 12 setae (eight sparsely plumose, two sparsely hardy plumose, and two sparsely hardy plumodenticulate); 4-segmented endopod with 3 (one plumodenticulate, one sparsely plumose, and one simple), 1 (sparsely plumose), 2 (sparsely plumose), 3 (terminal sparsely plumose); and unsegmented exopods with one subterminal plumose seta and three terminal plumose setae.
Second maxilliped (Figure 1I): Coxa unarmed; basis with six setae (two simple and four sparsely plumose) arranged like 1 + 2 + 3; 3-segmented endopod bearing 3 (one sparsely plumose seta and two simple arranged like 2 + 1), 2 (sparsely plumose), 6 (one subterminal simple seta and five terminal denticulate setae); 4-segmented exopod, bearing 1 + 1, 1 + 1, 1 + 1, 4 plumose setae.
Third maxilliped (Figure 1J): Coxa unarmed; basis with two sparsely plumose setae; endopod slightly longer than exopod and 4-segmented, bearing 2 (simple setae), 1 (simple seta), 5 (one median denticulate seta and four terminal denticutale), 3 (one denticulate, one serrate, and one simple seta); 4-segmented exopod bearing 1 + 1, 1 + 1, 1 + 1, 3 plumose setae.
First pereiopod (Figure 1K): Biramous bud.
Pleon (Figure 1A, B): Five pleomerers; sixth non-differentiated pleomere; third pleomere bearing a pair of small simple setae dorsally; fifth pleomere with a pair of dorsolateral spines and three small dorsal spines on the posterior margin. Pleopods absent.
Telson (Figure 1A, L): Triangular with 7 + 7 setae (two pairs of outermost setae plumose only on the inner side); minute spines between and around the setae (except the outermost pair). Uropod absent.
