| Diagnosis | DIAGNOSIS AND COMPARISONS. The only clear character that distinguishes the genus Ptyctolaemus from other genera of the subfamily Draconinae (sensu Macey et al. 2000) or Group V agamids (sensu Moody 1980) of mainland southeast Asia is that the males of P. gularis have longitudinal gular folds on either side of the midline with the posterior portion of the folds curving medially on each side of the throat. However, these folds are only evident when the gular pouch is in a relaxed position (as in preserved specimens). The folds are formed when the gular pouch is relaxed in an accordion-like fashion, the folds become more pronounced because the scales within the folds are darkly pigmented. The only other southeast Asian species with gular folds is Mantheyus phuwuanensis, however it has rounded “U”-shaped folds encompassing the gular sac. M. phuwuanensis also differs from Ptyctolaemus and all other draconines by the presence of femoral pores (Ananjeva and Stuart 2001). |
