Abstract The paper is devoted to the complex of pollinators from the tribe Mystropini collected on the inflorescences of the palms, cultivated or growing under natural conditions in South America, which includes Anthepurops depressa Kirejtshuk 1996; Anthocorcina subcalva Kirejtshuk & Jelínek 2000; Mystrops astrocaryi Kirejtshuk & Couturier n. sp.; M. atrata Kirejtshuk & Couturier n. sp.; M. bactrii Kirejtshuk & Couturier n. sp.; M. beserrai Kirejtshuk & Couturier n. sp.; M. costaricensis Gillogly 1972; M. dalmasi (Grouvelle 1902) n. comb.; M. delgadoi Kirejtshuk & Couturier 2009; M. discoidea Murray 1864; M. gigas Kirejtshuk & Couturier 2009; M. hisamatsui Kirejtshuk & Couturier 2009; M. kahni Kirejtshuk & Couturier n. sp.; M. komissari Kirejtshuk & Couturier n. sp.; M. lobanovi Kirejtshuk & Couturier n. sp.; M. neli Kirejtshuk & Couturier 2009; M. pectoralis Kirejtshuk, Couturier & Jelínek n. sp.; M. pulchra Kirejtshuk & Couturier 2009; M. rotundula Sharp 1889; M. squamae Kirejtshuk & Couturier n. sp.; M. vasquezi Kirejtshuk & Couturier n. sp.; Platychorodes adentatus Kirejtshuk & Couturier n. sp. The synonymy of the taxa is established. Mystrops corpulenta Jelínek 1969 is very similar and could be a variety of M. rotundula Sharp 1899. Palaeocorcina Jelínek & Kirejtshuk 2000 n. stat. is regarded as a separate genus. Lectotype are designated for Mystrops costaricensis pacificus, M. c. orientalis, M. debilis, M. discoidea, M. flavicans, M. insularis and Priops mexicanus. Diagnosis for larva of the tribe Mystropini is elaborated on base of the redescription of mature larva of M. debilis. The pollinators from the tribe Mystropini were studied from the next cultivated palms Astrocaryum vulgare, Bactris gasipaes and Elaeis oleifera; from the next palms in natural forests: Aiphanes ulei, Astrocaryum spp., Bactris maraja, B. cf. monticola, Ceroxylon quindiuense, Elaeis oleifera, Iriartea deltoidea, Mauritia flexuosa, M. carana, Oenocarpus bataua, O. mapora, O. multicaulis, Phytelephas macrocarpa, Phytelephas cf. tenuicaulis and Socratea salazarii, and also from Bactris gasipaes unknown in natural conditions. The palm tree Attalea funifera, also studied, is limited to the atlantic coast of Brazil.
