Diagnosis

Males of Tekellina picurrucha Rodrigues & Estol sp. nov. resemble those of T. helixicis (see Gao & Li 2014: fig. 72) by the terminal claw of the straight conductor, but differ by the shape of the cymbium and terminal claw closer to the apical part of cymbium ( Fig. 6A–B View Fig ). Females of Tekellina picurrucha resemble those of T. miuda Rodrigues & Estol sp. nov. and T. miudinha Rodrigues & Estol sp. nov. by the receptacles around the copulatory ducts, but differ by the course of the copulatory ducts not reaching the apical part of the receptacles and the receptacles close to each other ( Fig. 6C View Fig ).

Etymology

The specific epithet is derived from a popular Brazilian Portuguese expression and refers to its small size.
