Expression of hth paralogs in Parasteatoda tepidariorum. Expression of Pt-hth1 in the prosoma of embryos (a) during limb bud elongation, (b) inversion, and (c) dorsal closure, all in lateral-ventral view. d Frontal view of Pt-hth1 expression in the head of an embryo during inversion. e Lateral-ventral view of opisthosomal expression of Pt-hth1 during inversion. Prosomal expression of Pt-hth2 (f) during limb bud elongation, (g) inversion, and (h) dorsal closure, all in lateral-ventral view. i Frontal view of the head during inversion: no expression of Pt-hth2 is present in the head. j Opisthosomal expression of Pt-hth2 during inversion, lateral-ventral view. All embryos shown with anterior to the left, except (d) and (i) which are in frontal aspect. Abbreviations: hl, head lobes; lr, labrum; ch, chelicera; pp., pedipalps; L1-L4, walking legs pairs 1–4; O1-O5, opisthosomal segments 1–5; pe, posterior end of the germband
