RESUMO
An updated catalog of Collembola nominal species recorded in Colombia is herein provided, including two new records for the country: Entomobrya linda Soto-Adames, 2002 and Folsomides centralis (Denis, 1931), both found in Reserva Natural Mesenia - Paramillo (Antioquia Department). The data were obtained from the original descriptions, as well as secondary records surveyed until December 2022. I considered localities whose studies contained identification at generic level, but disregarded those who only contained records at family level. For each species, its type locality and general distribution were provided, in addition to the site of record in Colombia, which were plotted on a map. I also present the cumulative number of nominal species recorded and described from Colombia from 1929 to 2022. Colombia has now 38 nominal species (20 endemic) in 21 genera (one endemic, plus 19 without nominal species) and 16 families of Collembola distributed in 22 sites of the 11 departments and five regions. Of this total of families, Bourletiellidae, Collophoridae, Hypogastruridae and Sminthuridae only has generic records, no nominal species. Based on these data, an estimate of the species richness was made suggesting that at the current rate of species records, to recognize 231 to 250 more species (6-7 species every 10 years), it will take about 300 years, and even so this time will not be sufficient to unveil the real fauna of Collembola of the country. For that reason, these results suggest that the Collembola fauna from Colombia is still underestimated in relation to other countries from South America.
RESUMO
A new species of Troglopedetes Joseph from a Christmas Island Cave, Australia is described and illustrated here. Troglopedetes eberhardi sp. nov. resembles other species by presence of eyes and dorsal chaetotaxy of the second thoracic segment to third abdominal segment, but differs in head chaetotaxy, fourth abdominal segment and elongated unguis median tooth, which character is documented here in the genus for the first time. A comparison and identification key for all eyed species is provided. This is the first record of Troglopedetes for Australia and the genus now has 37 nominal species, of which nine have eyes.

Herein we describe a new species of Entomobrya Rondani from Cerrado biome, Brazil. Entomobrya uai sp. nov. differs from its congeners in having triangle-shaped spot on trunk, dorsal chaetotaxy pattern, unguis morphology, unguiculus inner lamella truncate, and manubrial plate with 913 chaetae and 3 pseudopores. Entomobrya barbata Siqueira Bellini known only from its type locality (Caatinga domain, Bahia state, Brazil), is herein recorded from Atlantic Forest (Minas Gerais, Paran and Santa Catarina states) and Cerrado (Gois state) biomes for the first time. The record of E. spectabilis Reuter in Brazil is herein dismissed due to a probable misidentification with E. barbata. From the description of E. uai sp. nov. and new records of E. barbata, the number of Entomobrya species in Brazil increased from 11 to 12 endemic species, and the genus is now recorded from 14 Brazilian states. In addition, this is the first record of a Collembola species from Distrito Federal and Gois state, Brazil.

Tyranonoseira is revised and new diagnostic characters to the genus and its species are proposed. The genus is now characterised by distinct chaetotaxic patterns of head, in lacking M2, S1, S4, S5 macrochaetae and Th II to Abd IV with 21-27, 7, 0, 3, 1 and 8-10 central macrochaetae, as well as anterior legs of males with modified chaetae. The five species of the genus are redescribed based on type material: T. raptora Zeppelini Bellini, T. bicolorcornuta Bellini Zeppelini, T. diabolica Bellini Godeiro, T. gladiata Zeppelini Lima and T. sex Bellini Zeppelini. We include an identification key and comparison of the species. The dorsal chaetotaxy is similar for all species. Characters omitted from the original descriptions such as chaetotaxy of the clypeus, labral papillae, collophore chaetae and manubrial formula are now used to distinguish species more clearly. We compare the morphology of Seira and Tyrannoseira using dorsal chaetotaxy and the modified chaetae on anterior legs of males.

The status of Heteromurini Absolon & Ksenemann is analyzed and a new diagnosis is proposed to the tribe. New chaetotaxic characteres were added to distinguish Dicranocentrus Schött and Pseudodicranocentrus Mari Mutt. Alloscopus Börner, Heteromurtrella Mari Mutt and Verhoeffiella Absolon, originally proposed as subgenera of Heteromurus Wankel, are reviewed and a new diagnosis and generic status are proposed. The presence of the postantennal organ becomes the main characteristic to distinguish Alloscopus (present) and Heteromurtrella (absent). Alloscopus yosiius Mari Mutt, anteriorly synonymized with Alloscopus tenuicornis Börner, is revalidated. The absence of S0 macrochaeta on head of Heteromurus is reported now as a characteristic also shared with Heteromurtrella. Heteromurtrella zairensis Tshelnokov comb. nov. is transferred from Heteromurus by the presence of macrochaetae on abdomen I. Heteromurtrella anae sp. nov. from Brazilian Amazon is described and illustrated, including detailed dorsal chaetotaxy. This is the first record of Heteromurtrella in Brazil. Heteromurus now has 17, Alloscopus 10 and Heteromurtrella 20 valid species worldwide. An identification key and diagnosis for the six genera of Heteromurini and species of Alloscopus and Heteromurtrella are provided.

Two new species of Seira, Seira tinguira sp. nov. and Seira paulae sp. nov. from Atlantic Rainforest Phytogeographic Domain in Paraná State, southern Brazil, are described and illustrated, with dorsal chaetotaxy labeled in detail. The general morphology of S. tinguira sp. nov. resembles S. frater (Bonet) and S. oceanica Yosii, however differs by chaeta Pa4 present in head, three extra macrochaetae (m1i2, p1i2 and one extranumerary) in mesothorax; four (a3, p2e, p2ea and a4) in metathorax; one (m3ep) in the second abdominal segment , among other morphological features. Seira paulae sp. nov. is similar to S. atrolutea (Arlé) in body colour, however dorsal chaetoxy resembles S. mendoncea Bellini & Zeppelini and S. ritae Bellini & Zeppelini. On the other hand, the new species clearly differs from other similar taxa by the presence of cephalic macrochaeta M2; three macrochaetae (M2, M1 and M2i) in mesothorax and p2p as microchaeta; one extra macrochaeta (p1i) in metathorax and two (a1 and p2ea) as macro or microchaetae; macrochaeta m3ep missing in the second abdominal segment; macrochaeta am6 present in the third abdominal segment among other features. Seira tinguira sp. nov. was found in different habitats of Paraná State while S. paulae sp. nov. was recorded only in its type locality. A distribution map is provided for both species. With the presented description there are now four recorded species of Seira from south Brazil.
