Durham distinguished this genus from Neolaganum only on account of its supposed lack of a groove for its hydropores. However, the specimen illustrated has its hydropores in a small, branched groove, as in Neolaganum. The slightly sunken nature of the oral surface, short, strongly lanceolate petals and the sparcity of tubercles surrounding the peristome are more significant differences. In petal structure Weisbordella closely resembles Durhamella, but that taxon has five, not four gonopores.
