Diagnosis. This species closely resemble Thyenula magna Wesołowska & Haddad 2009, but differs in the shape of the bulbus (broad in T. natalica and narrow in T. magna) and length of palpal tibia: long in T. magna (see Wesołowska & Haddad 2009, Figs 201–202) and short in T. natalica (Figs 61–62). It differs from other Thyenula in the shape of embolus that has a thin membrane (Figs 63–64).

Distribution. Republic of South Africa.

Comments. This species shares the synapomorphy of all Thyenula, viz. an embolus that forms a distal coil separated from the tegulum by the distal heamatodocha. We therefore transfer this species to the genus Thyenula (subfamily Euophryinae).
