This species raise the number  of known species to seven, three from Ecuador (T. vachoni, T. muranunkae and T. ballvei) and four from Colombia (T. humiculum T. hirsutus T. meijdeni and T. akaido)!

Peñareherrera-R. et al. (2024) described and published four new species of the until-now endemic ArachnoTrAC tarantula genus Cymbiapophysa (Theraphosidae) from Ecuador!

In a recent work published by Lopes (2024) on the comb-footed myrmecomorph spider genus Audifia (Theridiidae), the authors recorded for the first time A. laevithorax from the department of Beni, Bolivia, being this record also the first one of this genus for the ArachnoTrAC! More on Spiders!

Paredes et al. (2024) in a monograph on neotropical wolf spiders of the genus Arctosa (mainly) but also making taxonomic changes on Trochosa or Prolycosides, describes seven new species, five of which are now known from the ArachnoTrAC! Additionally, the authors review numerous new synonyms as well as transfers, helping to further clarify the taxonomic history of Neotropical wolf spiders! More on Spiders!

In a recent taxonomic revisionary work, Marta and colleagues (2024), the authors review the genus of jumping spiders Tullgrenella (Salticinae: Aelurillini) for the Neotropical region, describing three new species from Brazil and recording for the first time T. morenensis (type species of the genus) for the ArachnoTrAC and Bolivia! Thus we went from four species to five registered species of Tullgrenella from tropical Andean countries! More on Spiders!

A recent work published by Sherwood & Gabriel (2024) describes two new species of tarantulas of the genus Thrixopelma (Theraphosidae) from Peru, increasing the country's known species to nine! This genus is restricted almost exclusively to Peru, although there is one species known from Ecuador! More on Spiders!

In a recent taxonomic review work by Almeida-Silva & Brescovit (2024), the authors review the spider genus Goeldia (Titanoecidae) for the neotropical region, describing seven new species, two of which are now known from ArachnoTrAC! Thus we went from three species to eight registered species of Goeldia for the tropical Andean countries! More on Spiders!

Marta et al. (2024) in their recently published paper on Neotropical Chira Peckham & Peckham (Salticidae), updates the taxonomy of some of its species, illustrating them in high quality, useful for taxonomic determinations of some of these species which are known from the ArachnoTrAC!

Gorneau et al. (2024) revised by phylogeny the marronoid clade of spiders, ranking again as a family the previously recognized Macrobunidae! In the paper, the authors recognized the "unnatural" placing of some genera previously known to belong to Amaurobiidae, Dictynidae and Hahniidae, and now they placed them on Macrobunidae and Cicurinidae!

Dupérré & Tapia (2024) made a faunistic revision of the spider family Hahniidae for Ecuador, descriving 13 new hahniid species from the country in the previously known Amaloxenops (A. minimalista) and Neohahnia (N. catleyi, N. chalupas, N. freibergi, N. paramo, N. piemontana and N. pristirana), and in three new genera (Kasha, K. patpa; Paramito, P. oyacachi and P. papallacta; and Pristirana, P. barthlotti, P. niederi and P. nowickii)!
