Marginal process rather long, strongly curved to lateral side, ending juxtaposed to proximal part of apical plate, not projected distally over apical field of spines. Mesial process large, semicircularly shaped in mesial view, displaced to more apical position, with conical spine on distal portion pointing in caudomesial direction, its distal border clearly enlarged in caudal view, with some spinules apically. Mesial process separated from apical plate by slight concavity. Apical plate very strongly deflexed, bilobed; proximal lobe partially folded, forming narrow, digitiform projection pointing in latero-cephalic direction, slightly oriented towards basal side; distal lobe with rounded tip slightly shorter than proximal one. Field of apical spines moderately developed, narrow, basally oriented, bordered by “mesial” and “lateral” borders of apical plate but opened both proximally and distally.
