Figure 2. — Hypoconcha sabulosa: telson of zoeal stages 1 (A), II (B). and III (C), and megalopa (D). Only one disarticiilated uropod is 



shown for megalopa. 



Telson (Figure 2B) with reduced median notch; 

 setation 8+8 with small outer fixed spine, hair- 

 like plumose seta, and six large plumose setae. 



ANl (Figure 3B) — Indistinctly segmented; 

 terminal setation of five aesthetascs and three fine 

 simple processes; subterminal setation of two 

 large plumose setae and two or three short 

 plumose setae; additional one or two short setae 

 may be present along basal margin. 



AN2 (Figure 3F) — Similar to stage I with 19 

 plumose setae on scale and 3 plumose setae on 

 endopodite. 



MN — Similar to stage I; no palp. 



MAXI (Figure 5B) — With major features as in 

 stage I, basal endite (7 setae) and coxal endite (10 

 or 11 setael with additional fine setae as indicated. 



MAX2 (Figure 6B) — With two-segmented en- 

 dopodite, 5 setae distal, 3 setae proximal; bilobed 

 basal endite with 5 or 6 setae distal, 6 setae proxi- 

 mal; bilobed coxal endite with 4 setae distal, 11 

 setae proximal; and scaphognathite with 21-23 

 plumose setae. Setal types a mixture of simple, 

 plumose, and plumodenticulate. 



MXPl (Figure 7B) — Exopodite with six 

 plumose setae; endopodite as in stage I but with 

 two additional plumose setae on lateral margin. 



MXP2 (Figure 7F) — Exopodite with five 

 plumose setae, endopodite as in stage I but with 

 two additional plumose setae on lateral margin. 



MXP3 (Figure 71) — Exopodite with five 

 plumose setae; endopodite indistinctly segmented 

 with two to three plumose setae.
