Diagnosis

Males of Tekellina miuda Rodrigues & Estol sp. nov. resemble those of T. archboldi (see Levi 1957: figs 7–8) by the shape of the cymbium and by the long terminal claw of the conductor, but differ by the shape of the paracymbium more prominent and the terminal claw hook-shaped directed to the base of the cymbium ( Fig. 6D–E View Fig ). The females resemble those of T. miudinha Rodrigues & Estol sp. nov. by the long receptacles, totally wrapped around the copulatory ducts, but differ by the cylindrical shape of the receptacles and the copulatory opening separated by a median septum ( Fig. 6F View Fig ).

Etymology

The specific epithet means ‘little’ in the Brazilian Portuguese language and refers to the small size of the species.
