Vital Statistics

  • 2 species
  • Coral Finder p. 8, 28c
  • COTW – Vol 3 p.202-205

Distribution

Currently found in the Indo-Pacific.

ID Tips

Leptoria forms massive or encrusting colonies, often with lumpy protuberances.  It may be found on shallow reef slopes, although only one of the two species is found frequently.

The small corallites are hidden in narrow valleys bordered by neat, regular walls.  The walls are covered in uniform, evenly spaced septa that produce a zipper-like pattern.

Similar Genera

The Coral Finder lists Leptoria in one key group with Platygyra being the main source of confusion.

Similar genera to Leptoria (Coral Finder p8)

Leptoria can be confused with Platygyra but are easily separated by the v-shaped, narrow valleys of Leptoria. Platygyra tends to have more u-shaped valleys, furthermore, uniform septa are typical of Leptoria, whereas Platygyra has relatively ragged septa.
