Karyotype of Four Agamidae Species from the Phu Phan National Park in Thailand

Abstract

Karyotypes of Calotes emma (Gray), 1845, C. mystaceus (Dumeril & Bibron), 1837, C. versicolor (Daudin), 1802, and Draco belliana (Gray), 1827 from the Phu Phan National Park (Thailand) were investigated. Three species of genus Calotes have the same karyotype consisting of 2n = 34, 6 pairs of macrochromosomes and 11 pairs of microchromosomes. Their macrochromosomes of pair number 1, 3, 4, 5, and 6 are metacentric, and 2 is submetacentric. Karyotype of D. belliana are different from others. There are 6 pairs of macrochromosomes, 11 pairs of intermediate size chromosomes and 2 pairs of microchromosomes. Its chromosomes of pair number 1, 3, 4, and 6 are metacentric, the pair number 2 and 5 are submetacentric. Its intermediate size chromosomes of pair number 7 - 15 seem to be metacentric and the last 2 pairs are microchromosomes.
