Present Concept

Representatives of all genera and subgenera of Haliplidae are examined regarding the shape of the air storage under the metacoxal plates. Three different main types can be distinguished with strong variation in the species of Haliplus. In general the results support the present concept of genera and subgenera, but a few exceptions are found. The subgenus Phalilus is raised to genus level. The genera Algophilus Zimmermann and Apteraliplus Chandler are reduced to subgenera of Haliplus Latreille. The synonymised genus Haliaplus Ádám is re-installed as a subgenus of Haliplus. Three new subgenera are introduced: Australiplus, Borealiplus and Nipponiplus. A cladistic analysis is carried out using 27 characters including those of the metacoxal air-storage space. A cladogram to subgenus level is presented.

A cladistic analysis of Erotini (Lycidae) is carried out, resulting in revalidation of Dictyopterini nom. rev., proposal of Aferotini tr. n. and Flagraxina subtr. n. The genera Proteros gen. n. and Pyrotes gen. n. and eight new species: Proteros sempiternus sp. n., Taphomimus nanensis sp. n., Dictyoptera gansuensis sp. n., Helcophorus murzini sp. n., H. gobindanus sp. n., Greenarus belokobylskii sp. n., Eropterus glebulus sp. n. and Propyropterus (s. str.) plateroides sp. n. are described. Benibotarus sanguinipennis Nakane, syn. n. is placed in synonymy with Laterialis oculata (Gorham). Lycoprogentes Pic is transferred from Calochrominae to Taphini (Erotinae) and Microcoloberos Pic is transferred from Erotinae to Platerodinae. Erotides Waterhouse nom. rev. and Glabroplatyis Pic nom. rev. are revalidated from synonymy with Platycis Thomson. Punicealis miranda (Barovskij) nom. rev. is revalidated from synonymy with Laterialis oculata (Gorham). Platycis sculptilis (Say) is transferred to Erotides (s. str.), while Platycis cosnardi (Chevrolat), P. nasuta (Kiesenwetter), P. schneideri (Kiesenwetter), P. taiwana Kono, P. kanoi Nakane and P. matsudai Boc k are transferred to Erotides (Glabroplatycis); Benibotarus nigripennis Nakane & Ohbayashi is transferred to Greenarus Kazantsev and Pyropterus himalejicus Bourgeois to Lycoprogentes. Helcophorus Fairmaire, stat. n., Taphomimus Kazantsev, stat. n., Punicealis Kazantsev, stat. n., Laterialis Kazantsev, stat. n., and Greenarus Kazantsev, stat. n. are raised to the genus level, while Paralopheros Kazantsev is suppressed to subgeneric level within Propyropterus Nakane. The subgenus Tricostaeptera Kazantsev is transferred from Kolibaceum to Laterialis. Kleineria nom. n. is proposed for Kleinella Kazantsev, 1992 preoccupied by Kleinella Adams, 1860 (Mollusca). A key to the genera and subgenera and a check-list of Erotini and Dictyopterini of the World are provided.

Generic Relationships

Phylogenetic relationships of the subgroups of Parathalassiinae are presented, based on a morphological cladistic analysis. Worldwide, all known extant genera, species groups and newly discovered undescribed lineages are represented in the analysis. Some previously proposed generic relationships are supported by the analysis, but recognition of many current genera renders the present concept of Microphorella Becker as both paraphyletic and polyphyletic. Microphorella merzi Gatt is here classified in Eothalassius Shamshev & Grootaert, as Eothalassius merzi (Gatt) comb. nov. A preliminary classification with all included extant lineages within the Parathalassiinae (at the genus and species group level) is outlined. The ranking of these lineages is discussed and several species groups of Microphorella may need to be elevated to generic or subgeneric level, whereas some currently recognized genera may need to be relegated to subgenera.

First Time

A generic-level phylogenetic analysis of the tribe Torneutini Thomson, 1860 is presented based on 72 morphological characters for 39 terminal taxa of which, 31 are representatives of the Torneutini genera. The outgroup includes eight representatives from other tribes. A hypothesis of monophyly for supertribe Trachyderoinia Dupont, 1836 (sensu Fragoso, Monné and Seabra 1987) is presented for the first time. Torneutini, as currently recognized, was shown to be paraphyletic. In order to eliminate this condition, Bothriospilina Lane, 1950 is raised herein to tribe level. Torneutini, as herein defined, comprises the following genera in parenthetic notation: (Macellidiopygus (Psygmatocerus (Gigantotrichoderes (Spathopygus + Coccoderus) (Gnathopraxithea + Praxithea) (Torneutopsis (Torneucerus + Diploschema) (Torneutes (Dragomiris + Dragoneutes) (Thaumasus + Xenambyx)))))). The maintenance of Macellidiopygus in Torneutini needs further investigating. Bothriospilini Lane, 1950, new status, includes in parenthetic notation: ((Ranqueles + Scapanopygus) (Taygayba (Delemodacrys (Bothriospila + Timbaraba))) (Gnaphalodes (Knulliana + Chlorida)))). The position of Chrotoma is still no certain, and it is tentatively included in Bothriospilini. The results indicate that Bothriospilini is closely related to Trachyderini, Pyrestini and Basipterini. A phylogenetic classification of Trachyderoinia at tribe level, and of Torneutini and Bothriospilini at genus level, is proposed.

The cryptic assassin bug subfamily Physoderinae is characterized by a distinctly uneven species and genus-level diversity across continents, but the lack of a phylogeny has so far precluded investigations into the biogeographic history of the group. Endemic Madagascan Physoderinae (11 of the 15 genera) exhibit broad morphological diversity, but the large (38 spp.) and seemingly uniform genus Physoderes is widely distributed across the Oriental and Australasian regions. The three remaining genera are small or even monotypic and restricted to the Neotropical (Cryptophysoderes, Leptophysoderes) and Afrotropical (Porcelloderes) regions. To investigate relationships among Physoderinae, with emphasis on the monophyly of the Madagascan fauna and the monophyly of Physoderes, we conducted a cladistic analysis based on 57 morphological characters and complete genus-level taxon sampling. We found that the Madagascan fauna is not monophyletic, indicating that the island was colonized more than once, although the great majority of Madagascan taxa are part of a single clade. Overall relationships are recovered as Afrotropical Porcelloderes + [(Neotropical Cryptophysoderes, Leptophysoderes) + (Madagascan, Oriental and Australasian taxa)]. Physoderes is shown to be polyphyletic and 3 new genera, Breviphysoderes gen. nov., Macrophysoderes gen. nov. and Nanophysoderes gen. nov., are erected to accommodate new species and several species previously classified as Physoderes. A taxonomic revision of Physoderes and allied genera is conducted. Diagnoses, updated distribution ranges, habitus and genitalic images, and identification keys are provided. A total of 17 synonymies are given, and 15 new species and 3 new genera are described, focusing on the diversity of Physoderinae in the Oriental and Australasian regions. The new species are Breviphysoderes fulvopicta gen. et sp. nov., B. tenebrosa gen. et sp. nov., Macrophysoderes cirripilosa gen. et sp. nov., M. elongata gen. et sp. nov., M. finisterre gen. et sp. nov., M. grandis gen. et sp. nov., Paraphysoderes popeye sp. nov., Physoderes anamalaiensis sp. nov., P. brevipennis sp. nov., P. minime sp. nov., P. muluensis sp. nov., P. mysorensis sp. nov., P. nigripennis sp. nov., P. ractepilosa sp. nov. and P. tricolor sp. nov.

A cladistic analysis of the digger wasp tribe Bembicini based on morphological characters is presented. The underlying data matrix comprises 64 terminal taxa (coded on genus-level) and 54 morphological characters. The resulting strict consensus tree was used as the basis for a revised subtribal classification of the Bembicini. Based on a previously published classification, we herewith propose a number of changes. The subtribe Spheciina Nemkov and Ohl, subtrib. nov. (comprising Ammatomus A. Costa 1859, Kohlia Handlirsch 1895, Sphecius Dahlbom 1843, and Tanyoprymnus Cameron 1905) is removed from Handlirschiina Nemkov and Lelej 1996. The subtribe Stictiellina Bohart and Horning 1971, stat. resurr. (composed of Chilostictia Gillaspy 1983, Glenostictia Gillaspy in Gillaspy, Evans, and Lin 1962, Microstictia Gillaspy 1963, Steniolia Say 1837, Stictiella J. Parker 1917, and Xerostictia Gillaspy 1963) is separated from Bembicina Latreille 1802. The subtribe Argogorytina Nemkov and Lelej 1996 (Argogorytes Ashmead 1899, Neogorytes Bohart in Bohart and Menke 1976, Paraphilanthus Vardy 1995) is synonymized with Exeirina Dalla Torre 1897, syn. nov. Finally, the subtribe Trichogorytina Nemkov and Pulawski 2009 (genus Trichogorytes Rohwer 1912 only) is synonymized with Gorytina Lepeletier de Saint Fargeau 1845, syn. nov. An updated identification key to the subtribes of the Bembicini is provided.

The Standard Model

At the 1958 meeting of our society, then known as EMSA, the author introduced the concept of microspace and suggested its use to provide adequate information storage space and the use of electron microscope techniques to provide storage and retrieval access. At this current meeting of MSA, he wishes to suggest an additional use of the power of the electron microscope.The author has been contemplating this new use for some time and would have suggested it in the EMSA fiftieth year commemorative volume, but for page limitations. There is compelling reason to put forth this suggestion today because problems have arisen in the “Standard Model” of particle physics and funds are being greatly reduced just as we need higher energy machines to resolve these problems. Therefore, any techniques which complement or augment what we can accomplish during this austerity period with the machines at hand is worth exploring.
