Mites in the family Phytoseiidae from Central America (Belize, formerly British Honduras, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama) were reported by: Garman (1958) 1 species, Chant (1959) 8 species, Chant and Baker (1965) 38 species, De Leon (1966) 2 species, Denmark and Muma (1973) 2 species, Faerron (1974) 6 species, Denmark and Andrews (1981) 21 species, McMurtry (1983) 22 species, and Moraes et al. (1994) 2 species. Additional collections, including 40 new species, have been made by the last 4 coauthors from different countries in Central America. These collections total 138 species of phytoseiid mites collected from the Central American area.
Two new genera, Honduriella and Swirskiseius are described. The following 38 new species are illustrated and described: Amblydromella tecoma, Amblyseius faerrani, A. lencus, A. longicollis, A. perplexus, A. sculpticollis; Euseius lasalasi, E. passiflorus; Fundiseius cavei, F. costaricus, F. sentralus, Galendromus hondurensis; Honduriella maxima, Neoseiulus culpus, N. rufus, N. spicatus, N. ulatei, Paraseiulella bidentata; Proprioseiopsis acalyphae, P. penai, P. phaseoloides, P. trilobae; Swirskiseius zamaranus, Typhlodromalus julus, T. lunatus, T. tigrus; Typhladromips artemis, T. biflorus, T. bladderae, T. dombeyus, T. isthmus, T. jimenezi, T. laselvius, T. nectae, T. neoclavicus, T. oocarpus, T. parabufortus and T. vagatus.
The following new combinations are proposed; Arrenoseius fragosoi for Amblyseius fragosoi Yoshida-Shaul and Chant, Arrenoseius josephi for Amblyseius josephi Yoshida-Shaul and Chant, Proprioseiopsis belizensis for Amblyseius belizensis for Yoshida-Shaul and Chant, and Typhlodromalus manihoti for Amblyseius manihoti Moraes. Arrenoseius fragosoi (Yoshida-Shaul and Chant), Arrenoseius josephi (Yoshida-Shaul and Chant), Silvaseius barretoae (Yoshida-Shaul and Chant), and Typhlodromips amilus De Leon are illustrated and redescribed. Amblyseius vivax Chant and Baker, Typhlodromalus horatii De Leon and Typhlodromips bhoraii De Leon are placed in synonomy with Euseius fructicolus (Gonzalez and Schuster), Typhlodromalus arawak De Leon and Typhlodromips amilus De Leon, respectively. New Central American distribution records are listed for 12 species previously reported from other geographical regions.
