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.
