| Currently ninety-nine genera from the New World are assigned to the subfamily Hetaeriinae. Of these seventy-seven have been examined for this study. Fifteen genera (Inquilinister, Kleptisister, Glyptosister, Ulkeopsis, Opadosister, Reninoides, Reninopsis, Oudaimosister, Fistulaster, Leptosister, Eurysister, Oaristes, Gallaster, Daptesister, Daitrosister) are described as new. Three subgenera (Alloiodites Reichensperger, Metasynodites Reichensperger, Monotonodites Reichensperger) are elevated to generic status. Four genera (Brachylister Bickhardt, Hetaeriosoma Schmidt, Neolister Bruch, Pinaxister Reichensperger) are considered synonyms. Diagnoses are presented for sixty-two additional genera. The subfamily Hetaeriinae is subdivided into five groups on the basis of a preliminary phylogenetic analysis. Information concerning the behavior of ant- and termite-associated histerids is summarized. The morphological specializations of these histerids and the evolutionary trends within this subfamily are discussed. A key to the genera is provided for the identification of adults. One species of each genus studied is illustrated with scanning electron micrographs and where available outline drawings of the male genitalia. |
