Fig. 8. Expression of Cs-ci in embryos of the spider Cupiennius salei. (A) Segmentally iterated expression of Cs-ci in opisthosoma of young germ band stage embryo. (B) Slightly older embryo, new stripes form posteriorly. (C,D) Expression of Cs-ci is in the anterior part of the opisthosomal limb anlagen (C) and appendages (D), showing that Cs-ci is expressed in the engrailed negative cells. Anterior is towards the left in all embryos. Pp, pedipalps; L1-L2, walking leg 1-2; Opisthosomal segments are indicated by 1-12.
