Species Description:

Mini Description: Differentiated from A. insignis by the number of elements in the central "star?" On the areolated part of the sections the areolae are arranged in quincunx pattern with 6-7 areolae in each 10 µm.
Original Name Asterolampra schmidti Hajos, 1976: The disc is flat, heavily decorated. The areolated surface is divided by radial, hyaline areas in several sections whose number varies between 6 and 9. The areas are separated by radial ridges which are terminated in the center part of the disc forming a starlike pattern. The number of the sections is equal to the number of individual parts of the star, i.e., 6 to 9, however, this number may reach 21 by further division. On the areolated part of the sections the areolae are arranged in quincunx pattern with 6-7 areolae in each 10 µm.
