Diagnosis

Females of Tekellina miudinha Rodrigues & Estol sp. nov. resemble those of Tekellina miuda Rodrigues & Estol sp. nov. by the long receptacles, wrapped by the copulatory ducts, but differ by the oval funnel-shaped receptacles and wide copulatory opening without a medium septum ( Fig. 6G View Fig ).

Etymology

The specific epithet is the diminutive of ‘miuda’ in the Brazilian Portuguese language and refers to the small size of the species.
