Kier (1984) provides a detailed description of this species. In Habanaster the subanal fasciole passes over the suture between 5.b.2/5.b.3 and over the rear of 5.a.2. as in all Micrasteridae. It differs from Turanglaster in having a more elongate labrum that only just reaches ambulacral plate 2. In Turanglaster the labrum extends to ambulacral plate 4 and the plastron plating is much more primitive in arrangement.
