Morphology Variations of Hemidactylus frenatus in Java

Hemidactylus frenatus is one of the most widely distributed reptile species, almost all over Indonesia, including Java. The distribution is due to the process of merging and separation on some islands, which can lead to new morphological, anatomical and molecular characters that are very different as a result of adaptation. The aim of this study is to determine the distribution or philobiogeography of Hemidactylus frenatus by using morphometric analysis especially in the Java region, the data obtained is entered into Principal Component Analysis (PCA) and followed by cluster analysis. The result of this study was it found Hemidactylus frenatus samples from several regions which are divided into three provinces, namely East Java, Central Java, and West Java. The morphometric analysis of H. frenatus from the three provinces shows the grouping of H. frenatus according to the province of each individual, and can be seen also the similarity and difference character based on the biplot line. In the cluster analysis, there are two large H. frenatus groupings showed the degree of morphometric proximity among H. frenatus individuals from several regions of Java.
