Expression of dally in Euperipatoides (a–f), Parasteatoda (g–j), Tribolium (k–o) and Glomeris (p–t). In all panels, anterior is to the left. Ventral views, except for b, d and g (lateral views). The asterisk (*) in l mark future mesoderm. Arrows in m point to expression in the head lobes. Arrows in n point to regions of expression, while arrowheads point to regions of no expression. The arrow in t points to a dorsal transverse stripe of expression. a, anus; an, antenna; ch, chelicera; av, anal valve; ect, ecdoderm; fap, frontal appendage; hl, head lobe; j, jaw; L, walking leg; lr, labrum; mes, mesoderm; m, mouth; md, mandible; mx, maxilla; oc, ocular region; pp, pedipalp; saz, segment addition zone; sp, slime papilla; T, trunk segment
