The leiolepis ( Leiolepis ) are a lizard species from the family of Agamas (Agamidae). They live in mainland Southeast Asia , on some Southeast Asian islands ( Sumatra , Bangka , Tioman , Langkawi ) and in southern China ( Macau , Guangdong , Hainan , Guangxi ) and are particularly common on beaches.
features
Butterfly agamas are medium-sized, long-tailed agamas. The tail can reach twice the length of the head and trunk . Your body is slightly flattened and can be extremely widened and flattened with the help of the free-ended ribs. The limbs are strong, the head profile is blunt. There is no back or neck comb. The back is covered by very small, slightly keeled scales, the ventral scales are larger and smooth. The tail scales are strongly keeled. Both sexes have thigh pores.
Butterfly dragons rest in deep, self-dug holes in the ground. In Thailand they are eaten by humans.
Reproduction
Of the eight species of the butterfly agamas, the first four of the species listed below reproduce sexually, males and females mate, the eggs are fertilized in the womb. Of the four other species there are, however, only females through parthenogenesis multiply. Prior to meiosis , a form of cell division , in which the number of chromosomes is halved, a doubling takes the chromosomes held and temporarily creates a tetraploid primordial germ cell , which then passes through a normal meiosis, so that normal diploid oocytes produced.
External system
The butterfly agamas were until recently, together with the Afro-Asian thorn- tailed agamas ( Uromastyx ), in the subfamily Uromasticinae. Since the butterfly dragons are more closely related to all other agamas than to the thorn-tailed dragons and are the sister genus of all agamas without thorn-tailed dragons, they were placed in their own subfamily, the Leiolepidinae. The family relationships are shown in the following cladogram :
