The Lygosominae are a subfamily of the Skinks (Scincidae).

features

Diagnostic features of the Lygosominae are nine teeth on the premaxillary , a Meckelian groove (an opening in the middle (inner) surface of the lower jaw from which the Meckel's cartilage originates) that is completely closed by overlapping and fused lower jaw bones . The two parts of the pair of parietal bones ( os parietale ) touch each other behind the interparietal. The parietal bone is bounded along its posterior lateral edges by two or more temporal bones. The nuchal is usually missing. The inner preanal scales overlap the outer ones, the scales on the top of the fourth toe are arranged in several rows. The iris is lighter than the pupil. The hemipenis consists of a short, columnar base and a bulbous tip.

Systematics

The Lygosominae include 52 species:

The subfamily Lygosominae was established in 1952 by the herpetologist Myron Budd Mittleman. In 2014, the herpetologist Stephen Blair Hedges suggested giving the group the rank of family (Lygosomidae).
