8); posterior margin of metasternum straight or at most only weakly emarginate
, bearing a number of minute black spinules but lacking a medial lobe or prominence (Fig.
It has 2-winged indehiscent pods (Dwyer and Hermann, 1965) which are elliptical in outline with an acuminate apex and emarginate
apex, and slight stylar protrusion.
Diagnosis: Caudal fin emarginate
, lobes acute; caudal concavity 13-22% SL; branched rays 13.
Connective trapezoidal, caudal margin emarginate
the pelvic fins, which are loosely attached in the young, become lost; the limp skin encroaches more and more over the anterior ends of the dorsal and anal fins thus giving a low count of the rays except under dissection; the modified scales disappear; the character of the pectoral and caudal fins is changed from round to pointed in the former, and from round to broadly emarginate
in the latter; the yellow color and purplish spots change to a more somber brown as the adults attain greater size.
Anterolateral margins of pronotum not convex or conspicuously emarginate
Paracheilinus piscilineatus Comic, 1987 from Mauritius also lacks filamentous extensions of the dorsal fin rays, but has a truncate to slightly emarginate
caudal fin and very different colouration (Fig.
1], apex bluntly rounded; ventral tooth absent; dorsal depression present, prominent, incomplete, clearly observable anterior to tertiary row of spurs; dorsal edge broadly, shallowly emarginate
between apical and primary rows; ventral ridge small, parallel to dorsal depression.
5 cm in diameter, rachis stout and concealed by the bracts, densely white-lanate; primary bracts oblong-ovate, obtuse to slightly emarginate
and minutely apiculate, nerved, densely and conspicuously white-farinose-lepidote with trichomes obscuring its the color, stramineous, thin in texture toward the apex, erect or nearly so, ecarinate, entire, apical margins conspicuously undulate, concealing the branches but not the petals, 60 x 30-35 mm; primary branches ca.
Valva moderately elongate; dorsal margin slightly concave medially; ventral margin gently emarginate
at basal 1/3; cucullus more or less quadrate with rounded outer margin, with dense, strong setae along near margin.
