Exostoma oschanini, presently treated as a junior synonym of Glyptosternon reticulatum, is revalidated within Glyptosternon based on a phylogenetic analysis of the CO1 gene and morphological characters. Glyptosternon oschanini is known to occur in tributaries of the Syr Darya River in Uzbekistan and Kyrgyzstan and may also occur in the Amu Darya River drainage. A morphological diagnosis and description are provided for G. oschanini. Exostoma gracile is a junior synonym of G. oschanini rather than of G. reticulatum.

Bombyliinae, one of the largest subfamilies of Bombyliidae, including 78 genera assigned to four tribes, is distributed on all continents except Antarctica. Their larvae are parasitoids, and adults are important pollinators. The Australian Bombyliinae currently has 17 described genera and 87 described species. The purpose of this study is to establish the phylogeny of the Australian members of the subfamily Bombyliinae, including the boundaries and relationships of the genera, using morphological characters. One maximum parsimony tree was generated from 83 morphological characters scored for 50 species, representing all recognised genera and some unplaced species that we considered may represent new genera. Phylogenetic analysis recovered the relationships between the recognised Australian genera of Bombyliinae and clarified generic limits. The group comprises five main clades, with the genus Pilosia being sister to the remaining Bombyliinae. On the basis of this analysis, four new genera are described: Lambkinomyia Li & Yeates, gen. nov., Dissodesma Bowden & Li, gen. nov., Nigromyia Li & Yeates, gen. nov. and Robertsmyia Li & Yeates, gen. nov. Ten new species are described: Dissodesma immaculata Li & Yeates, sp. nov., Dissodesma flava Li & Yeates, sp. nov., Dissodesma smarti Li & Yeates, sp. nov., Nigromyia collessi Li & Yeates, sp. nov., Nigromyia crocea Li & Yeates, sp. nov., Nigromyia flavimana Li & Yeates, sp. nov., Nigromyia longistriata Li & Yeates, sp. nov., Nigromyia pantherina Li & Yeates, sp. nov., Nigromyia parva Li & Yeates, sp. nov. and Nigromyia tomentosa Li & Yeates, sp. nov. Two new junior synonyms are identified: Apiformyia is a junior synonym of Eristalopsis and Brychosoma is a junior synonym of Staurostichus. The following new combinations are proposed: from Apiformyia: Eristalopsis australis (Yeates), comb. nov.; from Bombylius: Dissodesma primogenita (Walker) comb. nov.; from Brychosoma: Staurostichus aureolatus (Walker), comb. nov., Staurostichus hilaris (Walker), comb. nov. and Staurostichus pictipennis (Macquart), comb. nov.; from Laurella: Robertsmyia pallidoventris (Roberts), comb. nov.; from Mandella: Lambkinomyia cinctiventris (Roberts), comb. nov., Lambkinomyia flavovillosa (Roberts), comb. nov., Lambkinomyia pallida (Roberts), comb. nov. and Lambkinomyia rubida (Roberts), comb. nov.; and from Meomyia: Mandella australis (Guérin-Méneville), comb. nov. http://zoobank.org/urn:lsid:zoobank.org:pub:E4A86A19-4AC3-498C-8BDF-B8B501E5A248

Abstract Holopothrips is a diverse group of thrips associated to galls in the Neotropics, with a variety of host plants and wide morphological diversity. Relationships to other Neotropical groups have been proposed, but are still untested, and the monophyly of the genus remains doubtful. Here, we perform a phylogenetic analysis of Holopothrips, based on morphological characters. A total of 87 species were included in the matrix and eight analyses were carried out, but all of them failed to recover Holopothrips as a monophyletic grouping. Bremer and Bootstrap support values were low, and the topologies varied among all analyses, with uncertain internal relations for the ingroup. These results indicate that the relationships for Holopothrips species, and the proposed related genera, are more complex than previously reported; and morphological characters may not be enough to recover the evolutionary story within this group. We also discuss the influences of different character coding, continuous characters and weighting schemes in our results.

Morphological characters of adults of the treehopper subfamily Nicomiinae Haupt, 1929 (Hemiptera, Membracidae) including seven genera (Eudonica gen. nov.; Euwalkeria Goding, 1926; Holdgatiella Evans, 1962; Nicomia Stål, 1858; Nodonica Dietrich, McKamey& Deitz, 2001; Stalomia gen. nov.; and Tolania Stål, 1858) and 22 species (16 new) are described and illustrated. Keys are provided for genera and for species of Euwalkeria, Holdgatiella, and Nicomia. Nomenclatural changes, based on study of the primary type material of 15 species, include three new combinations, one new synonymy, and reinstatement of one junior synonym. Eudonica has one species, Eudonica nanella sp. nov.; Euwalkeria has five species, including four new species: E. colorata sp. nov., E. distincta sp. nov., E. perdita sp. nov., E. rubrica sp. nov.; Holdgatiella has two species, one of which is described as new: Holdgatiella chiloensis sp. nov.; Nicomia has twelve species, nine of which are described as new: N. buccina sp. nov., N. harenosa sp. nov., N. inscripta sp. nov., N. jucunda sp. nov., N. monticola sp. nov., N. nigrifasciata sp. nov., N. notidana sp. nov., N. pulchella sp. nov., N. serrata sp. nov.; Nodonica has one species, Nodonica bispinigera Dietrich, McKamey & Deitz; and Stalomia has one species, Stalomia veruta sp. nov. Tolania contains eleven previously described species and nearly 60 new species, which will be treated in a later publication. Three new combinations are proposed: one species described in Nicomia is placed in the tribe Abelini (Centrotinae) as Abelus retrospinosus (Lethierry) comb. nov.; one species previously placed in Nicomia is transferred to the genus Tolania as T. obliqua (Walker, 1858), comb. nov.; one species described in Holdgatiella is placed in the genus Tolania as T. stria (Cryan & Deitz, 2002), comb. nov. One new synonymy is proposed: Hoplophera [sic] cicadoides Walker, 1862, syn. nov., a junior synonym of Nicomia interrupta Stål, 1858. Nicomia subfasciata Stål, 1858, is reinstated. The results of a phylogenetic analysis based on morphology are presented, illustrating the hypothesized relationships among species and genera of Nicomiinae. The analysis supports the broader concept of Nicomiinae proposed here. The monophyly of this group is supported by eleven characters, and all of the included genera are also monophyletic.

Parsimony Criterion

Abstract Prodidominae was recently re-established as a subfamily of Gnaphosidae, comprising 316 species placed in 33 genera. In this study, we conduct a cladistic analysis including 59 species of Prodidominae and 32 outgroup species. The matrix is composed of 291 morphological characters and the data are analysed under the parsimony criterion, using differing weighting regimes. Prodidominae is not recovered as monophyletic, because Anagrina did not arise within the subfamily. Cryptotoerithus, Molycria, Myandra, Nomindra, Wesmaldra and Wydundra arise to form a clade. Thus, we re-establish Molycriinae as a distinct subfamily in Gnaphosidae, sister to Prodidominae. We redefine the limits of Prodidominae to include the genera Austrodomus, Brasilomma, Caudalia, Chileomma, Chileuma, Chilongius, Eleleis, Indiani, Katumbea, Lygromma, Lygrommatoides, Moreno, Namundra, Neozimiris, Nopyllus, Paracymbiomma, Plutonodomus, Prodidomus, Purcelliana, Theuma, Theumella, Tivodrassus, Tricongius, Zimirina and Zimiris. Species of these genera share the presence of anterior lateral spinnerets with pyriform gland spigots associated with patches of long setae and the presence of a large protrusion between coxae IV with erect setae and unsclerotized margins. In addition, we propose three new synonymies: Oltacloea as a junior synonym of Tricongius, and Prodida as junior synonym of Prodidomus. Lygromma ybyguara is transferred to Tricongius.

A phylogenetic analysis of selected anomuran, thalassinidean, and other decapod crustacean taxa, based on spermatozoal ultrastructural characters and spermatophore morphological characters, was performed and the following relationships of the taxa are elucidated from the trees produced. The Anomura are not a monophyletic assemblage, with the lomoid Lomis being exclusive of the remainder of the anomuran taxa, and the thalassinid Thalassina included in the anomuran clade. The synapomorphy joining the majority of the conventional anomuran taxa (Lomis excluded) is the cytoplasmic origin of the microtubular arms. When the palinurid and thalassinoid representatives are separately designated as outgroups, the Astacidea and Brachyura jointly formed a sister group to the Anomura. The superfamilies Thalassinoidea, Paguroidea, and Galatheoidea are not monophyletic groups. In all analyses the anomuran families Coenobitidae and Porcellanidae each form a monophyletic group. The paguroid family Diogenidae is paraphyletic, with the genera Clibanarius and Cancellus separate from a single clade containing the remaining diogenid genera. The families Paguridae and Parapaguridae form a monophyletic clade with the exception of Porcellanopagurus. The two representatives of the family Chirostylidae (Eumunida and Uroptychus) fail to associate with the other species in the Galatheoidea. The taxa in the family Galatheidae are not a monophyletic assemblage. The only investigated hippoid Hippa is portrayed as the sister group to the remainder of the anomuran taxa (with the exception of Lomis).

In this study, the Amu Darya river basin, Syr Darya river basin and Balkhash lake basin in Central Asia were selected as typical study areas. Temporal/spatial changes from 2002 to 2016 in the terrestrial water storage (TWS) and the groundwater storage (GWS) were analyzed, based on RL06 Mascon data from the Gravity Recovery and Climate Experiment (GRACE) satellite, and the sum of soil water content, snow water equivalent and canopy water data that were obtained from Global Land Data Assimilation System (GLDAS). Combing meteorological data and land use and cover change (LUCC) data, the joint impact of both human activities and climate change on the terrestrial water storage change (TWSC) and the groundwater storage change (GWSC) was evaluated by statistical analysis. The results revealed three findings: (1) The TWS retrieved by CSR (Center for Space Research) and the JPL (Jet Propulsion Laboratory) showed a decreasing trend in the three basins, and the variation of TWS showed a maximum surplus in spring (March–May) and a maximum deficit in autumn (September–November). (2) The decreasing rates of groundwater storage that were extracted, based on JPL and CSR Mascon data sets, were −2.17 mm/year and −3.90 mm/year, −3.72 mm/year and −4.96 mm/year, −1.74 mm/year and −3.36 mm/year in the Amu Darya river basin, Syr Darya river basin and Balkhash lake basin, respectively. (3) In the Amu Darya river basin, annual precipitation showed a decreasing trend, while the evapotranspiration rate showed an increasing trend due to an increasing temperature, and the TWS decreased from 2002 to 2016 in most areas of the basin. However, in the middle reaches of the Amu Darya river basin, the TWS increased due to the increase in cultivated land area, water income from flooded irrigation, and reservoir impoundment. In the upper reaches of the Syr Darya river basin, the increase in precipitation in alpine areas leads to an increase in glacier and snow meltwater, which is the reason for the increase in the TWS. In the middle and lower reaches of the Syr Darya river basin, the amount of evapotranspiration dissipation exceeds the amount of water replenished by agricultural irrigation, which leads to a decrease in TWS and GWS. The increase in precipitation in the northwest of the Balkhash lake basin, the increase in farmland irrigation water, and the topography (higher in the southeast and lower in the northwest) led to an increase in TWS and GWS in the northwest of the Balkhash lake basin. This study can provide useful information for water resources management in the inland river basins of Central Asia.

Two distinct new species of the ant genus Crematogaster, C. khmerensis sp. nov. and C. pfeifferi sp. nov., are described from Cambodia and Malaysia, respectively. The two species are unique among Asian Crematogaster in that they have vertically directed propodeal spines, but their systematic positions have not been determined based on morphological characters alone. Molecular phylogenetic analysis of 89 Crematogaster taxon matrices previously published plus C. khmerensis sp. nov., using nuclear genes, reveals that C. khmerensis sp. nov. is nested within the Australo-Asian Crematogaster clade. Morphological assignment of the developed pronotal shoulders implies a close relationship between C. khmerensis sp. nov. and the C. tetracantha-group. Based on molecular and morphological evidence, we erect a new species group, C. khmerensis-group, to contain C. khmerensis sp. nov. and C. pfeifferi sp. nov. Divergence time estimates using MCMCTree shows that the root node of the C. khmerensis sp. nov. terminal is estimated to be of middle Miocene age at 15 million years old. The position of the C. khmerensis-group well supports the Oriental- to Australian-region dispersal history that has been proposed for the Australo-Asian Crematogaster clade.

Thyestetha Pascoe, an apterous genus of Papuan Cryptorhynchinae is revised. It contains two previously describedspecies, T. carbonaria Faust and T. nitida Pascoe, plus seven new species: T. discolor sp. n., T. emarginata sp. n.,T. glabra sp. n., T. lubrica sp. n., T. oblita sp. n., T. puncticollis sp. n., and T. splendens sp. n.. Lectotypes are designatedfor T. carbonaria, T. nitida, and Pantoxistus rubripennis Chevrolat which is a junior synonym of T. nitida (syn. n.). Thegenus and its species are described and the characters relevant for their identification are illustrated. A key to the speciesis provided. Phylogenetic analyses are performed, utilizing molecular and morphological approaches. A maximumlikelihood tree including 5 Thyestetha species and 2 outgroups is presented, based on 3 mitochondrial and 4 nuclearmarkers. A maximum parsimony analysis of 19 morphological characters includes all described species. Thyestetha ispresumably closely related to Telaugia Pascoe and Elichora Pascoe. The group is restricted to New Guinea and some smaller neighboring islands.
