description: Genus Kamilocella gen. nov.   
(Figure 16)  
 Type species   
 Eschara latilabris Reuss, 1872. Cretaceous, late Cenomanian (Actinocamax plenus ammonite Zone), Hoher Stein Quarry, Dresden-Plauen, Saxony, Germany.   
 Diagnosis   
Colony erect bilaminar or encrusting, sometimes multilamellar. Autozooids pyriform; zooidal boundaries marked by grooves. Cryptocyst containing a peripheral cavity in all or most autozooids, leaving the remaining part surrounding the opesia upstanding. Gymnocyst lacking. Opesia subterminal, occupying about one-third of the frontal surface, roundish or transversely elliptical, lacking opesiular indentations or constrictions. Ovicells hyperstomial,?exterior-walled (Figure 16 (a,d)). Avicularia vicarious, slightly smaller than autozooids (Figure 16 (c)), bilaterally symmetrical; opesia roundish, located centrally, usually with a median proximal slit; rostrum pointed.  
 Etymology   
 For Czech bryozoologist Kamil Zágoršek, with the suffix ‘– cella ’ taken from Onychocella. Remarks   
The new genus is erected for erect bilaminar or encrusting onychocellid species with very thick calcification of the cryptocyst that usually develops a depression surrounding a raised portion around the opesia. This ‘raised’ cryptocyst or ‘insula’ in the sense of Voigt (1956) takes the appearance of a beard (Figure 16 (b,c)) while the depression has been described as a type 2 peripheral cavern by Koromyslova et al. (2018). Peripheral caverns are found only in a few onychocellids and coscinopleurids (Voigt 1956; Taylor and McKinney 2006; Koromyslova et al. 2018).  
 The type species is found in the late Cenomanian of Dresden-Plauen, Saxony, Germany, and the late Cenomanian/early Turonian of Kaňk, Central Bohemian Region, Czech Republic (Počta 1892; Voigt 1989). Whether the specimens described as latilabris from the late Cenomanian of the Aqtash Mountain, Tashkent Region, Uzbekistan (Favorskaya 1990, 1996) are really conspecific is unclear. In addition to the type species, the following species are referred to the new genus: (1) Eschara acis d’ Orbigny, 1851, from the Cenomanian to Campanian of several French localities in (the original material of this species needs revision and is likely to represent more than one species); (2) Onychocella aff. acis (d’ Orbigny, 1851) from the late Cenomanian of Dohna-Kahlebusch, Saxony, Germany (Martha et al. 2017); (3) ‘ Onychocella ’ barbata Martha, Niebuhr and Scholz, 2017 from the late Cenomanian of Dresden-Plauen, Saxony, Germany; (4) Eschara cenomana d’ Orbigny, 1851 (= Biflustra cenomana d’ Orbigny, 1852) from the middle Cenomanian of Le Mans, Pays de la Loire, France and (5) Eschara labiata Počta, 1892; from the early Turonian of Kaňk, differing from the sympatric type species in having opesiular indentations (Voigt 1989). Other, as yet undescribed, species assignable to the new genus are common in Cenomanian strata of Western Europe.   
 Range   
Cretaceous (middle Cenomanian to Campanian).
