Fig. 6 in The puzzling taxonomic rank of Pijnackeria hispanica, a chimerical hybrid androgen (Insecta, Phasmida)

Fig. 6 Karyotype of the triploid Pijnackeria masettii (on the top) and of the tetraploid Pijnackeria hispanica (on the bottom) modified from Scali et al. (2013). P. masettii triplets 1–4, 6, 12, 17– 19 clearly support a 2 + 1 structure; 1st, 2nd, 13th, 15th, and 19th quartets of P. hispanica seem to suggest either a 2 + 2 structure or, better, a 2 + 1 + 1 structure
