AB  - We analyzed the phylogenetic relationships of the genusTrisetacususing two genes [cytochromecoxidase subunit I (COI) and D1-D2 region of 28S rDNA (D1-D2 28S)], a representive taxon sampling (nearly 40% of known diversity), and a large set of close and distant outgroups. Our analyses suggest the presence of a dichotomy betweenTrisetacusassociated with Cupressaceae and Pinaceae. The following smaller molecular clades were found:Pin-1(bud mites, twig sheath mites, bark gall mites, and endoparasitic mites from pinaceans),Pin-2(needle sheath mites from pines),Pin-2a(putative Nearctic group of needle sheath mites),Pin-2b(putative Palearctic group of needle sheath mites),Cup-1and2(bud, cone, seed mites and mites living under bark scales from cupressaceans). The monophyly of the recently proposed subgenusBrevithecusnested within cladeCup-2was confirmed. Ancestral character reconstruction analyses recovered: (1) Pinaceae as the ancestral hosts of Nalepellidae andTrisetacus, (2) repetitive reductions of the spermathecal tube independently occurred in two lineages ofTrisetacusfrom Cupressaceae, and (3) several mite habitats on host (galls, cones, twig sheaths, seeds, inside leaves, and under scales) are evolutionarily derived states, whereas living in buds or needle sheaths are ancestral states forTrisetacuscladesCupandPin. Using confocal microscopy, we identified six basic types of the female internal genitalia ofTrisetacusbased on shapes of the spermatheca and spermathecal tube. These genitalic types are strongly correlated with lineages recovered by molecular phylogenetic analyses, suggesting that the female genital morphology is both evolutionarily conserved and is a factor influencing macroevolutionary patterns in this group of mites.

AB  - A new vagrant eriophyoid mite species, Setoptus tsugivagus n. sp. Chetverikov (Eriophyoidea, Phytoptidae, Nalepellinae, Nalepellini), is described from the needles of the western hemlock, Tsuga heterophylla (Rafinesque) Sargent (Pinaceae) in Vancouver, Canada. The new species can be distinguished from all other members of Setoptus by a distinct pattern of several short longitudinal ridges on the posterior half of the prodorsal shield. Elements of the anal secretory apparatus (ASA) were observed in adults of S. tsugivagus n. sp., suggesting that the ASA is present in both major phylogenetic lineages of Eriophyoidea (Eriophyidae s. l. and Phytoptidae s. l.). Therefore, this structure could be a synapomorphy for all Eriophyoidea. We briefly discuss the function and morphological variety of the ASA in Eriophyoidea. D2 28S rDNA sequences of four nalepelline species were obtained: Boczekella reticulata Bagnyuk 1987 (GenBank accession number MK124605), Nalepella tsugifoliae Keifer 1953 (MK124606), Setoptus pini Boczek, 1964 (MK124607), and S. tsugivagus n. sp. (MK124608). Molecular phylogenetic analyses of D2 28S rDNA sequences of the mites of the subfamily Nalepellinae confirmed monophyly of the tribe Nalepellini and retrieved Setoptus and Nalepella as polyphyletic. Additionally, our data indicate that 28S rDNA sequence KF782472.1, previously reported to be Trisetacus ehmanni Keifer 1963 by Li et al. (2014), belongs to another species of the genus Trisetacus, possibly T. quadrisetus (Thomas), and the sequence KF782471.1, previously reported to be Trisetacus sp., might belong to T. juniperinus (Nalepa). We also discuss the systematics of nalepellines and their host association with conifers.
