As a result of their feeding habits, birds of 36 or more families have proved to be susceptible to a large number of dicrocoeliine trematodes living principally in the bile ducts and gall-bladder of their hosts (Faust, 1966). As more species of avian hosts are examined and their liver flukes studied, additional species are described and previously recognized species are reported from new hosts and new geographical areas (Lumsden and Zischke, 1963).In 1958, Yamaguti differentiated Dicrocoeliinae Looss, 1899 into 8 tribes, one of which he named Lutztrematini, having as cardinal characters an acetabulum much larger than oral sucker and testes tandem or diagonal; single genus Lutztrema Travassos, 1941 and L. obliquum (Travassos, 1917) as type species. The avian dicrocoeliine species described in this communication has important morphological characters agreeing with the Lutztrematini and others lacking agreement. In consequence, it has seemed necessary to create a new genus, Paralutztrema, related to, but generically separate from Lutztrema.

A New Species

A cladistic analysis based on 274 morphological characters was performed including the 13 previously recognized speciesof the scale mite genus Hirstiella, 2 new species, 5 species in closely related genera, and 3 more distant out-group species.An analysis based on 148 informative characters resulted in one most parsimonious tree (L = 400, CI = 0.57 and RI =0.79). According to this, the genus Hirstiella in its current concept is a polyphyletic taxon whose member species belongto three different clades. The first lineage (Bremer support and jackknife values 2 and 78%) includes the type species H.trombidiiformis and seven additional species of Hirstiella that are parasites on iguanian lizards. The genus Geckobiella isincluded in this lineage, and the latter taxon name has priority over Hirstiella; therefore, the genus Hirstiella is considereda synonym of Geckobiella and no longer valid. For the second lineage (Bremer support and jackknife values of 2 and 73%)we propose the name Bertrandiella gen. nov.; it includes H. tenuipes, H. otophila, H. jimenezi and Bertrandiella chame-laensis sp. nov. The third lineage, and sister taxon of Bertrandiella, is a clade comprising Pimeliaphilus and the speciesH. sharifi and H. insignis. The latter taxa are transferred back to Pimeliaphilus (Bremer support and jackknife values >4and 100%). Updated diagnoses are provided for the genera Geckobiella sensu nov. (including a new species Geckobielladonnae sp. nov.) and Bertrandiella gen. nov., and for all their species, as well as for the genera Pimeliaphilus sensu nov.and Tequisistlana, based on the results of the phylogenetic analyses. The analyses support the hypothesis that lizards arethe ancestral hosts for Pterygosomatidae; associations with arthropods (in Pimeliaphilus) appear to be secondary, the result of host switching from lizards.

Claviplatysgen. n. and its type species C.henryisp. n. (Hemiptera: Heteroptera: Plataspidae: Plataspinae) are described from Kerala, India. The new genus is related to the Indomalayan genera Heterocrates Amyot & Serville, 1843, Cratoplatys Montandon, 1894, and Cronion Bergroth, 1891, but differs from them and all other plataspid genera by the peculiarly modified antenna. The morphological characters and systematic relationships of the above genera are discussed.

The Hawaiian spider genus Orsonwelles, gen. nov. (Araneae : Linyphiidae) is described. All Orsonwelles species are single island endemics: Kauai harbours six species; Oahu has three; Molokai has two; and Maui and Hawaii have one species each. The thirteen species included in Orsonwelles are described and illustrated: O. torosus (Simon), comb. nov., O. malus, sp. nov., O. calx, sp. nov., O. ventus, sp. nov., O. bellum, sp. nov. and O. iudicium, sp. nov. from Kauai; O. polites, sp. nov. (the type species), O. ambersonorum, sp. nov. and O. arcanus, sp. nov. from Oahu; O. othello, sp. nov. and O. macbeth, sp. nov. from Molokai; O. falstaffius, sp. nov. from Maui; and O. graphicus (Simon), comb. nov. from Hawaii. A total of 55 morphological characters (plus one behavioural character) were scored for twelve taxa (four Orsonwelles species plus eight linyphiid outgroups) to test the monophyly of the genus using cladistic methods. The most parsimonious cladograms provide robust character support for the monophyly of Orsonwelles. A single colonisation of the Hawaiian archipelago is hypothesised to explain the presence of these species in the Hawaiian Islands. This genus represents a case of insular gigantism (these are the largest linyphiids described), although the close relatives of Orsonwelles remain unknown. Their web architecture is also described and illustrated.

The spider genus Putaoa new genus (Araneae, Pimoidae) is described to place two species of pimoids from China, Putaoa huaping new species (the type species) and P. megacantha (Xu & Li, 2007) new combination. Parsimony analysis of morphological characters provides support for the monophyly of Putaoa and for its sister group relationship to the genus Weintrauboa Hormiga, 2003 and corroborates the monophyly of Pimoidae.

Mite Family

Unlike most terrestrial parasitengone mites (chiggers, erythraeids), known mostly from parasitic and easy-to-collect larvae, smaridid systematics are mainly based on the post larval instar. Larvae are rarely collected, and their biology and host associations are virtually unknown. Here we infer phylogenetic relationships of Smarididae based on 50 morphological characters using both larval and post larval instars, including data on the larval morphology of Trichosmaris obtained through rearing. The subfamily Smaridinae, as currently understood, was recovered paraphyletic: the genus Smaris was rendered as basal smaridid lineage, while the genus Fessonia (Smaridinae) was sister to Hirstiosomatinae, albeit with moderate support. Our analysis suggests that the genus Surasmaris Southcott, 1995 is a junior synonym of Trichosmaris Southcott, 1963 (syn. nov.), and two Sphaerotarsus species should be placed into Hirstiosoma: Hirstiosoma baenai (Mayoral & Barranco, 2017) comb. nov., Hirstiosoma quercus (Yazdanpanah, Saboori & Hakimitabar, 2016) comb. nov. Sphaerotarsus monticolus Southcott, 1997 and S. leptopilus were recovered as independent lineages, and hence, a new genus Southcottiana gen. nov. is proposed to include Southcottiana monticola comb. nov (Southcott, 1997). We describe two new species, Trichosmaris paulensis sp. nov. (adults, larvae) and T. calcarensis sp. nov. (larva), and present the first description of larval T. dispar, the type species of Trichosmaris, previously known only from post larval instars. Based on the above results, we give a key to larval genera of Smarididae and a key to species of Trichosmaris (larval and postlarval instars).

Life History Data

Amorbimorpha Kruse, new genus, is described and illustrated. The genus ranges from Texas, U.S.A., south through Ve-racruz, Mexico, with greatest species richness documented from the middle to upper elevations of central Mexico. Twospecies are described as new: A. powelliana (type species) and A. mackayiana; the latter is the only species in the genusknown from the U.S.A. Also, two new combinations are proposed: A. schausiana (Walsingham, 1913) and A. spadicea(Walsingham, 1913). Male and female genitalia are illustrated for each species where known; A. spadicea is representedby a unique female. Limited biological and life history data are summarized based mainly on laboratory rearings from eggs deposited by confined females of A. powelliana. At least ten additional species remain to be described.

Neochloroglyphica gen. nov. and its type species N. perbella sp. nov. are described from Yunnan, China. Morphological characters and molecular phylogenetic analysis, based on one mitochondrial and three nuclear genes, support the hypothesis that Neochloroglyphica is a member of the tribe Neohipparchini, and that it is a sister genus to Chloroglyphica. Morphological characters, including those of the genitalia, are figured and compared with related genera, especially Chloroglyphica, Neohipparchus and Chlororithra. Diagnoses for the genus and the species are provided and illustrations of external features and genitalia are presented.

A new genus of the primitively segmented trapdoor spiders, which is endemic to the north of China, is described, Luthela gen. nov., and the status of Sinothela Haupt, 2003 and Sinothela sinensis (Bishop & Crosby, 1932) is discussed and both are treated as nomina dubia. The new genus Luthela gen. nov. is erected based on morphology and molecular data of the type species Luthela yiyuan sp. nov. A taxonomic revision of the new genus is given. Three Sinothela species are transferred to the new genus, L. luotianensis comb. nov. and L. schensiensis comb. nov. are redescribed using our newly collected specimens, include L. heyangensis comb. nov. as a junior synonym of L. schensiensis comb. nov., and describe six new species based on both male and female morphological characters: L. badong sp. nov., L. dengfeng sp. nov., L. handan sp. nov., L. taian sp. nov., L. yiyuan sp. nov., and L. yuncheng sp. nov.
