T y p e: Syntypes deposited in the Natural History Museum Vienna under number 1867.40.187 (David and Pouyet, 1974).
M a t e r i a l: Altogether 32 specimens were investigated from many of the studied sections.
D i a g n o s i s: Autozooecia oval with a smooth frontal wall. Marginal areolar pores are small, there are about 20-30 pores at the border of each autozooecium. Aperture oval with small condyles and with spines situated on the distal margin of the aperture. Peristome short. Avicularia oval with long, narrow palate always tapering distally. Ovicell immersed into the distal part of the autozooecium; globular, with small marginal areolar pores. Ectoecium perforated by small pores.
R e m a r k s: The main distinction from Escharoides coccinea (ABILDGAARD, 1806) is the granular frontal wall; moreover the avicularia are smaller in Escharoides megalota (REUSS, 1847).

Escharoides coccinea (ABILDGAARD, 1806) – Zágoršek p. 158, P. 23, Fig. 3 (cum syn.)
M a t e r i a l: Altogether 5 specimens were studied, mainly from the section at Podbřežice. Additional specimens from the Reuss collection are stored in the Natural History Museum Vienna under the number 1859.19.154 (as Lepralia lima – holotype) from the section of Sedlec.
D i a g n o s i s: Autozooecia oval to triangular with strongly granulated frontal wall. The granules are sometimes arranged in ribs. Marginal areolar pores are intermediate in size, there are about 12-18 pores on the border of each autozooecium. Aperture oval with small condyles and with spines situated on the distal margin of the aperture. Non-ovicelled autozooecia have about 8 spines, ovicelled ones have about four spines. Peristome very short or absent with a prominent lyrula. Avicularia oval with long, narrow palate. Ovicell conspicuous, globular, with small marginal areolar pores. Ectoecium granular and perforated by very small pores.
R e m a r k s: This species is relatively common in the Recent Mediterranean, there are no differences between fossil specimens and the illustration and description of recent ones (for example Hayward and Ryland, 1999). Also the type of Lepralia lima REUSS, 1974 shows identical features when compared with recent specimens, so I decided to list this material under the name of the recent species.
