Etymology. The specific epithet is an honor to LMAS’s sister, Elisabete Almeida (Bete Diva), who is a professional opera singer and performer. The word entered the English language in the late 19th century and it is derived from the Italian noun diva, a female deity or goddess. The meaning of diva is closely related to prima donna, Italian for “first lady”, the leading female singer in an opera company.
Diagnosis. Goeldia diva sp. nov. differs from the other species by the tegular process long, with an acute tip and broad membranous base (Fig. 9A); and by the patellar apophysis thick and posteriorly curved (Fig. 9B–D) on the male palp. The female can be distinguished by the epigynum wide but with lateral rims not covering the copulatory openings (Fig. 9E); horizontal spermathecae distally projected anteriorly (Fig. 9F); vertical spermathecae with the same height as the copulatory ducts and distally curved (Fig. 9F).
