The taxonomy of the T. bessonii, T. bonibony, T. dysalum, T. marginatum, T. tsingy, and T. weitzeckeri species groups isrevised. A total of 33 species is treated, of which 27 are newly described and one is raised to species status. The T.weitzeckeri group contains the single species T. humbloti Forel, which is of Afrotropical origin and the only representativeof the group in the Malagasy region. The species T. bessonii Forel, T. dysalum Bolton, T. marginatum Forel, and T. stein-heili Forel, which were originally members of the T. weitzeckeri group, are now placed in other groups. Tetramorium bes-sonii is the core species of the T. bessonii group, which also contains the four newly described species T. artemis sp. n., T.malagasy sp. n., T. ryanphelanae sp. n., T. wardi sp. n., and T. orientale Forel stat. n., which was a junior synonym of T.bessonii but is now raised to species rank. The T. dysalum group is a moderately-sized group with ten species, of whichonly T. dysalum and T. steinheili were previously known; the other eight species are all newly described. The newly described species in this group are: T. ambatovy sp. n., T. macki sp. n., T. mallenseana sp. n., T. orc sp. n., T. robitika sp. n.,T. sargina sp. n., T. yammer sp. n., and T. vohitra sp. n. A lectotype and several paralectotypes of T. steinheili are desig-nated. Tetramorium marginatum is the central species of the T. marginatum group, which also includes the five newly de-scribed species T. valky sp. n., T. hector sp. n., T. norvigi sp. n., T. shamshir sp. n., and T. silvicola sp. n. The T. bonibonyand T. tsingy groups represent completely new groups that consist entirely of previously unknown, undescribed species.The first group holds the new species T. bonibony sp. n., T. kali sp. n., T. sada sp. n., T. nosybe sp. n., T. olana sp. n., T.popell sp. n., and T. trafo sp. n. and T. vony sp. n. The last group, the T. tsingy group, only contains the two species T. tyrionsp. n. and T. tsingy sp. n., both among the rarest Tetramorium species in Madagascar. All groups are fully revised withillustrated species-level identification keys, and all species are described/re-described and illustrated with high qualitymontage images. In addition, the current status of the Malagasy Tetramorium species groups is discussed and further modifications are proposed.

The North American fauna of Drymeia Meigen was studied. Four new species are described (Drymeia huckettisp. nov., Drymeia pontisp. nov., Drymeia vockerothisp. nov., Drymeia woodorumsp. nov.), and three new synonymies are proposed: Drymeia amnicola (Huckett, 1966) (= Drymeia rivalis (Huckett, 1966), syn. nov.); Drymeia glacialis (Rondani, 1866) (= Drymeia alpicola (Rondani, 1871), syn. nov.); and Drymeia spinitarsis (Aldrich, 1918) (= Drymeia longiseta Sorokina & Pont, 2015, syn. nov.). An annotated checklist, DNA barcodes (when available), and keys for each sex of the 24 named species of North American Drymeia are provided. The utility of DNA barcodes for the identification of Drymeia species across a wide geographical range was explored using sequences from five countries. A match between morphology and DNA barcodes was found for 71% (22/31) of species studied (including three unnamed taxa). The remaining nine species clustered into two groups of taxa with very little interspecific variation within clusters (groups of two and seven species). Caution is advised against using DNA barcoding as the only determination tool for Drymeia material without prior knowledge of its limitations for certain species groups.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.

The morphology of the genus Scapheremaeus Berlese, 1910 is reviewed and characters of taxonomic utility delineated. Based on the morphological review, some 13 species-groups are outlined based on major morphotypes. There are two main categories: i) species that have a complete circumdorsal scissure with plicate microsculpture on the circumnotogastral plate and strongly contrasting microsculpture (foveolae, ridges or tubercles) on the centrodorsal plate (plicate species-groups), and ii) species with the circumdorsal scissure complete, incomplete or absent but with little or no contrast in microsculpture between the central and lateral regions: typically both regions foveolate or reticulate (non- plicate species-groups). A catalogue of world species of Scapheremaeus is provided. Scapheremaeus petrophagus (Banks, 1906) is not a Scapheremaeus but belongs to an undetermined genus in the Ameronothroidea. Cymbaeremaeus cyclops Oudemans, 1915 is recombined to Scapheremaeus. Five new species are described (S. angusi sp. nov., S. cheloniella sp. nov., S. ewani sp. nov., S. lambieae sp. nov., and S. pulleni sp. nov.) from soil and litter habitats in semi-arid Mallee eucalypt vegetation at Bookmark Biosphere Reserve, South Australia. These are the first members of the genus Scapheremaeus to be described from Australia, though undescribed species have been recorded previously. All the new species are morphologically closely-related and belong to a single species-group: Carinatus.

A New Species

Of the 16 species listed in the genus Liophloeothrips (ThripsWiki 2018), 13 are known only from India, and all of these are phytophagous with some inducing galls in various plant families (Tyagi & Kumar 2011). However, the biology of the type species, L. glaber, as well as that of the other two species, L. hungaricus and L. pulchrisetis, remains in doubt. Each of these three species is from Europe, with L. pulchrisetis known from a single female, L. glaber from two specimens, and hungaricus recorded from Hungary, Finland and Iran on a very few individuals (Minaei & Mound 2014). The record of L. hungaricus from Iran was published without any information concerning the locality, date of collection, or number of specimens (Mortazawiha 1995). However, Minaei and Mound (2014) pointed out that the slide label data of L. hungaricus specimens from Europe suggested that this species is associated with the bark of certain Salicaceae. Moreover, they indicated the possibility that the three names might actually represent a single species, although the male of L. glabrus has a sternal pore plate whereas this is apparently absent in hungaricus. Given the few known specimens, it is not possible to know if these thrips live under bark and feed on fungal hyphae, or if the few specimens collected were actually leaf-feeders that were sheltering under bark. In this paper, a new species of the genus is described from southern Iran, based on both sexes. These specimens were extracted from leaf litter using a Berlese funnel, thus again it is not possible to be certain if the species is part of the community of fungus-feeding litter thrips, or if the specimens were merely sheltering.

Within the scorpion genus Vaejovis C.L. Koch, the “mexicanus” group is composed of species distributed in the mountains of México. This group presents taxonomic problems, because its characterization and the species included in the group have varied through the years. In the present work, we redefine this group based on several morphological characters, and we differentiate it from the other two species groups within the genus: “vorhiesi” and “nit dulus+nigrescens”. Additionally, five new species are described: Vaejovis ceboruco sp. nov., Vaejovis nanchititla sp. nov., Vaejovis santibagnezi sp. nov., Vaejovis talpa sp. nov. and Vaejovis tapalpa sp. nov; the males of three species are described for the first time (V. dugesi, V. nigrofemoratus and V. tesselatus); and the updated diagnosis for all species is included. Keys for the identification of males and females of the 30 species included in this group are given. Lastly, notes on the natural history and distribution of some species are provided, with maps of known distribution for all the species.

The Australian ants of the genus Monomorium are revised. Fifty-nine species are recognised. Of these, 41 are described as new: Monomorium aithoderum, M. albipes, M. anderseni, M. anthracinum, M. arenarium, M. bifidum, M. bihamatum, M. brachythrix, M. burchera, M. capito, M. carinatum, M. castaneum, M. crinitum, M. decuria, M. disetigerum, M. draculai, M. durokoppinense, M. elegantulum, M. eremophilum, M. euryodon, M. flavonigrum, M. lacunosum, M. legulus, M. longinode, M. macarthuri, M. majeri, M. megalops, M. micula, M. nanum, M. nightcapense, M. nigriceps, M. parantarcticum, M. petiolatum, M. pubescens, M. ravenshoense, M. rufonigrum, M. shattucki, M. silaceum, M. stictonotum, M. striatifrons, and M. xantheklemma. Thirteen species pass into synonymy: M. armstrongi with M. whitei, M. broomense and M. ilia with M. laeve, M. donisthorpeiand M. fraterculus with M. fieldi, M. flavipes and M. insularis with M. leae, M. foreli with M. sordidum, M. howense with M. tambourinense, M. macareaveyi with M. bicorne, M. sanguinolentum with M. rubriceps, M. subapterum with M. rothsteini, and M. turneri withM. gilberti. Sixteen infraspecific forms are also synonymised: M. kilianii obscurelluminto M. kilianii, M. laeve nigriusand M. laeve fraterculus into M. fieldi, M. ilia lamingtonensisinto M. laeve, M. rothsteini humilior, M. rothsteini leda, M. rothsteini doddi and M. subapterum bogischi into M. rothsteini, M. rothsteini squamigena, M. rothsteini tostum and M. sordidum nigriventris into M. sordidum, M. fraterculus barretti and M. sydneyense nigella into M. sydneyense, M. gilberti mediorubra into M. gilberti, and M. rubriceps cinctumand M. rubriceps rubrum into M. rubriceps. Seventeen species and one subspecies are unchanged. Monomorium kiliani reverts to M. kilianii, M. kilianii tambourinenseis raised to species status, M. occidaneus is here treated as a species inquirenda, and M. flavigaster is removed from the genus Monomorium. Since the generic status of the latter taxon is uncertain, M. flavigaster is here regarded as incertae sedis. The supposedly extralimitalMonomorium talpa is synonymised under Monomorium australicum. At a higher taxonomic level the South American genus Antichthonidris is synonymised under Monomorium. Seven species-groups are proposed for the Australian fauna, (the bicorne-, falcatum-, insolescens-, kilianii-, longinode-, monomorium-, and rubriceps-groups). A cladistic analysis was undertaken of species for which all castes were examined (identifiable males and/or queens were lacking for all members of the falcatum-, insolescens- and longinode-groups). In all, fifteen species of Australian Monomorium were examined (M. bicorne, M. whitei, M. striatifrons and M. rufonigrum from the bicorne-group, M. crinitumand M. kilianii from the kilianii-group, M. fieldi, M. laeve, M. rothsteini, M. sordidum and M. sydneyense from the monomorium-group, and M. centrale, M. leae, M. euryodon and M. rubriceps from the rubriceps-group), together with Monomorium antarcticum(from New Zealand) and the Neotropical Antichthonidris denticulatus. The taxon used for the outgroup was the Neotropical ant Megalomyrmex modestus. Using the PAUP program, 37 characters for worker, queen and male castes were analysed. The clade incorporating the tiny generalists (M. fieldi, M. laeve, M. sordidum, and M. sydneyense), together with M. rothsteini, was found to be the clade most strongly supported as a monophyletic grouping. In this analysis M. euryodon was the sister taxon to the above clade. These ants were shown on this analysis to share a common ancestor with the other members of the rubriceps-group, with M. antarcticum and A. denticulatus, and with thekilianii-group. The relationships between these latter four sets of species were left unresolved, except that M. crinitum was shown to be the sister taxon to M. kilianii. The large, arid zone species in thebicorne-group were also shown as ancestral to the other Australian Monomorium. A key is provided to enable researchers to identify the workers of all Australian Monomorium, as well as extralimital species established in Australia.

The endemic Hawaiian nitidulid genus Apetasimus is revised and a key to species provided. Originally described for a single species, Apetasimus involucer, five new species are described and five species are moved from the endemic Hawaiian genus Orthostolus. The following new species are described: Apetasimus conditus sp. nov., A. ganeademus sp. nov., A. abstrusus sp. nov., A. pleomelarrosus sp. nov., and A. debbiae sp. nov. Six species previously assigned to Orthostolus and the monotypic Cyrtostolus are moved to Apetasimus; Apetasimus guttatus comb. nov., Apetasimus sordidus comb. nov., Apetasimus expers comb. nov., Apetasimus atratus comb. nov., Apetasimus kauaiensis comb. nov., and Apetasimus subalatus comb. nov. Apetasimus are arranged in three species groups: pleomelarrosus-group, involucer-group, and guttatus-group. The involucer-group is characterized by brachyptery, and are rarely collected. The pleomelarrosus-group is fully winged and one species, A. pleomelarrosus, is locally abundant on Kauai. One member of the guttatus-group, A. subalatus, is brachypterous. All guttatus-group species are presumed extinct, with the last known collection in 1935.

Aenigmetopia Malloch is the only endemic genus of miltogrammine flesh flies (Diptera:Sarcophagidae) in Australia and, until now it has been known from a single species, A. fergusoni Malloch. This study constitutes the first comprehensive taxonomic revision of Aenigmetopia. Four new species, Aenigmetopia amissa, sp. nov., A. corona, sp. nov., A. kryptos, sp. nov. and A. pagoni, sp. nov., are described through the integration of molecular and morphological data and characters for genus- and species-level diagnoses are given. Aenigmetopia is included in a molecular phylogenetic analysis for the first time and the genus emerges as the sister taxon to Metopia Meigen, in agreement with morphological evidence.
