Feather Mites of the Aralichus canestrinii (Trouessart) Complex (Acarina, Pterolichidae) from New World Parrots (Psittacidae). II. From the Genera Aratinga Spix, Deroptyus Wagler, Leptosittaca Berlepsch and Stolzmann, Ognorhynchus Bonaparte, Pionites Heine, and Pyrrhura Bonaparte, and Conclusions to the Study Abstract For the genus Aralichus Gaud (Pterolichidae, Pterohchinae), one species is redescribed, three species have new host records, one species has new locality records, and seven new species are de-scribed. Redescribed is A. inermis (Megnin and Trouessart) from Pionites leucogaster. New rec-ords: A. {'?)canestrinii (Trouessart) from Ara au-ricollis, and A. nobilis Atyeo from nine species of Aratinga and nine species of Pyrrhura. New lo-cality records: A. araraunae Atyeo from Ara ara-rauna, Panama, Ecuador, Bolivia, Guyana. New species described: Aralichus aratingae from Ara-tinga aurea, A. nana, and A. pertinax; A. glau-cogularis from Ara glaucogularis; A. leptosittacae from Leptosittaca branickii; A. lunatus from Der-optyus accipitrinus; A. ognorhynchi from Ogno-rhynchus icterotis; A. truncatus from Aratinga au-ricapilla and A. jandaya; and A. weddellii from Aratinga weddellii. Aralichus leptophyllus (Canes-trini and Kramer) [= Pterolichus (Eupterolichus) leptophyllus = Pterolichus (P. ) hemiphyllus micro-phyllus Megnin and Trouessart] is considered in-certae sedis. Host-commensal associations and the biology of Aralichus nobilis are discussed. A key to all species of the canestrinii complex is pre-sented. Introduction One extensive complex of feather mites from New World parrots includes Aralichus canestrinii (Trouessart) and numerous related species. The first part of this study considered the species from the parrot genera Ara Lacepede and Anodorhyn-chus Spix (Atyeo, 1988) in which 1 named and 1 1 new species were (re)described. Two additional studies were planned, as it was originally consid-ered that a one host-one commensal association would exist for all Aralichus species. However, in this study we found that some species exist on more than one host species. Therefore, in this sec-ond and final study, the remaining species of the A. canestrinii complex will be (re)described. The study collection, preparation of illustrations and SE>ecimens, abbreviations for typ)e reposito-ries, definitions of measurements, general mor-phology of Aralichus, relationships of Aralichus canestrinii complex to other pterolichid taxa, and a generic diagnosis were presented in Part I (Atyeo, 1988)— these will not be repeated. To facilitate identification, a few of the illustrations from Part I are repeated, and all recognized species of the A. canestrinii complex are included in a new key. If the number of mite specimens per host species exceeds 10, measurements are given as mean ± standard error followed by the observed limits (ol) and the number of specimens (N) in parentheses; when N is less than 10, only the mean, observed limits, and N are recorded. A few new measure-ments are included; specifically, the distances be-tween setal pairs and setal rows in the male genital region (figs. 25, 66, 70). Tarsal lengths are rede-fined; each is measured from the mesal articulation to seta d (or seta /for male tarsi IV) (figs. 7, 9), rather than to the tarsal apex as in Part I of this study. Distances between the anterior genital setae ATYEO & PEREZ: ARALICHUS CANESTRINII II.
