FIGURE 3 in Relationships, evolution and biogeography of Semaphore geckos, Pristurus (Squamata, Sphaerodactylidae) based on morphology

FIGURE 3. Apparent relationships of the main taxa of Sphaerodactylidae based on 19 morphological characters equivalent to 21 binary ones. The tree shown is a strict consensus of three produced by parsimony analysis; figures indicate bootstrap support for nodes based on 1000 replicates. Derived states that characterize apparent clades are as follows (character numbers are given in parentheses. A. Loss of cloacal tubercles (8), loss of cloacal sacs and bones (9, 10), clutch size reduced to a single egg (16). B. Small body size (1), voice reduced (19), active in subdued light (17-1). C. Pupil rounded but often higher than wide (6.1), sexual dichromatism often present (11), 'escutcheon' often present (13), active in bright light (17-2), voice reduced (19). D. Nasal bones relatively short (2), pupil round (6-2), characteristic dorsal pattern (12), 'escutcheon' dark (14), tail often raised as intraspecific signal (18).
