Abstract
An updated checklist of chiggers from the family Trombiculidae and Leeuwenhoekiidae is presented, with 81 species in 38 genera parasitizing different terrestrial vertebrate hosts in Panama. The depository for all Panamanian records, including new localities and host-associations records for the species Blankaartia sinnamaryi (Floch and Fauran, 1956), Eutrombicula tinami (Oudemans, 1910), Eutrombicula goeldii (Oudemans, 1910), Hooperella vesperuginis (Brennan and Jones, 1960), and Pseudoschoengastia bulbifera Brennan, 1960 were provided.
Highlights
The first chigger described from Panama was Odontacarus dentatus (Ewing, 1925), originally described as Trombicula dentata Ewing, 1925 (Ewing 1925b)
Among the countries that have a great diversity in this region with a compiled checklist were Brazil (63 species – Jacinavicius et al 2018), Chile (25 species – de Silva-de la Fuente et al 2020), and Peru (37 species – Brennan and Jones 1961) stand out, but still having a smaller number of species of chiggers when compared to Panama or Venezuela
The chiggers of Panama are represented by seven species of Leeuwenhoekiidae Womersley, 1944 and 74 of Trombiculidae Ewing, 1944, for a total of 81 species in 38 genera parasitizing 185 different hosts
Summary
The first chigger described from Panama was Odontacarus dentatus (Ewing, 1925), originally described as Trombicula dentata Ewing, 1925 (Ewing 1925b). Soon after, Brennan and Yunker (1966) compiled a catalog for Panama, which recorded 76 species organized in 29 genera. Compared to other countries in South and Central America, only Venezuela has the most significant diversity of chiggers, having 136 species in 38 genera (Brennan and Reed 1975). Among the countries that have a great diversity in this region with a compiled checklist were Brazil (63 species – Jacinavicius et al 2018), Chile (25 species – de Silva-de la Fuente et al 2020), and Peru (37 species – Brennan and Jones 1961) stand out, but still having a smaller number of species of chiggers when compared to Panama or Venezuela. We included new host associations and locality records for five species of chiggers
