Chromosomes of first meiotic division in males of the Jollas-Tomis clade 129, 130 Attinella concolor, with only seven pairs of autosomes, but each two-armed, 14m+Xm0, Florida (29.63N, 82.37W) 131 Tomis manabita, showing the two Xs off to one pole, and 13 acrocentric bivalents on the metaphase plate, Ecuador (0.9S, 80.5W) 132–136 Sittisax ranieri, whose distinctive XmXaYm appears as a rabbit head with a droopy ear. White triangles show points where two bivalents are apparently linked together 134–136 details of XXY of S. ranieri 137–139 Sittisax saxicola, with sex chromsomes, interpreted tentatively as XaXaXaYm, appearing as a rabbit head with three ears, Switzlerland (46.9N, 9.2E).
