Sentence:  This figure emphasizes the dislocation of the pigment bands and presents the so-called nymphalid <WSD>groundplan</WSD>: the set of pattern elements out of which butterflies build their wing patterns (Nijhout 1991). The <WSD>groundplan</WSD> thus consists of eight parallel series of pattern elements: one for each band of each of the three symmetry systems, a row of border ocelli, and a set of submarginal bands. Each wing cell has a representative of each of these pattern elements so the overall <WSD>groundplan</WSD> can be viewed as a serial repetition of the same set of pattern elements. 
Meaning of the word marked with <WSD> tags:  A hypothetical anatomical form from which members of a clade are adaptations.
