Remark. Keyserling (1891) described Trechona pantherina based on a small female from Taquara do Mundo Novo (now Taquara, state of Rio Grande do Sul, Brazil). He stated the specimen has two rows of teeth in the STC, in litt.: “Klauen haben 2 Reihen Zähnchen”. This character is widespread in diplurids and pycnothelids, and in Theraphosidae it is present only in males (Raven 1985). In the same paper, he described another species in Trechona, T. auronitens Keyserling, 1891, based on a male from the same locality. This species is now in the genus Pycnothele Chamberlin, 1917 ( Pycnothelidae), as synonym of P. auripila (Mello-Leitão) (World Spider Catalog 2023). Therefore, it is highly probable that T. pantherina is also a pycnothelid. However, since the type is probably lost and the information given in the description is not enough to allow the species identification, I consider Trechona pantherina a nomen dubium.
