Genus Allotherenia gen. nov.
Type species. Allotherenia sabulosa sp. nov.
Etymology. From the Greek, allos, other, for the similar appearance to Therenia David & Pouyet, 1978 , a related escharinid genus.
Diagnosis. Escharinidae with pseudoporous frontal shield, and developed proximal collar. Orifice almost circular, with shallow proximal sinus; condyles present; articulated oral spines absent. Avicularia absent. Ovicells hyperstomial, with smooth ooecium, closed by operculum of maternal zooid.
Remarks. Allotherenia gen. nov. is closely related to Therenia by virtue of its similar frontal shield, perforated by numerous pseudopores and with a few larger marginal pores (see Berning et al. 2008); it is distinguished from Therenia by the hyperstomial ovicell and absence of avicularia. Bryopesanser Tilbrook, 2006 , also has a perforated frontal wall and hyperstomial ovicells, but has oral spines and paired lateral-oral avicularia with fan-shaped mandibles.
