Nomenclature note for this paper: MS was formerly MSt, U was E, Y was C, W was P0.a, QL was Q1, and QR was Q2.

WA editors' note: In this paper, the positions of the descendants of Caaa and Cpaa are reversed in Figures 7a (260 min), 10 (290 min), 13 (L1) and 14 (L1). At 260 min, the four nuclei descended from Caaa are to be found on the left of the dorsal midline and those from Cpaa on the right. At about 310 min of embryogenesis, most of the dorsal hypodermal nuclei migrate across the midline to reside on the side opposite to that of their origin (Fig. 10). Thus, after this stage, the four descendants of Cpaa reside on the left side and Caaa on the right side (Figs. 13 and 14a). Note that Fig. 5 is correct with Caa to the left (and anterior) of Cpa (Loer C. et al, WBG 10(3):120).
