On the basis of Kluge’s (1982) paper on post-cloacal sacs and bones in the Gekkota the following matters are presented: (1) the situation in the gekkonid genera Microscalabotes and Paragehyra is recorded, (2) the situation in the gekkonid genus Lygodactylus is extensively reviewed and commented upon, (3) the post-cloacal sac variability in the gekkonid genus Thecadactylus, first noted by Hoogmoed (1973) and evidently overlooked by Kluge, is confirmed and commented upon, (4) Kluge’s interpretation of the phylogenetic significance of post-cloacal sacs is discussed.
