Antenna of nauplii of Capitulum mitella. A: N3, Left lateral view of labrum, antenna and mandible. Both appendages in a stance where they “guard” the ventral feeding chamber behind the labrum. B: N5, Right antenna dissected loose and shown in oblique dorsal view. Note naupliar process on coxa (cxpr), naupliar process on basis (bapr) with a F-plumose seta (arrow), and three prominent F-plumose setae on endopod segment 1 (asterisks). C: N5, endopod, showing fringe of thin hairs along the outer side and plumose setae (vague in this picture) along the inner side. D: N3, distal segment of antennal endopod; the two ventral-most of the four distal setae are fused in their basal part (arrowhead). E: N2, end of antennal exopod, anterior view; two setae on the terminal annulus. F: N6, distal end of antennal exopod, anterior view, with four setae on the last annulus. Legends: a2, antenna; ba, basis; cx, coxa; en, endopod; en1–2, endopodal segment 1–2; en1–3, endopodal segment 1–3; ex, exopod; md, mandible.
