We here treat four unreported or poorly known mayfly species from Jordan: Cheleocloeon soldani Gattolliat & Sartori, 2008, Cloeon vanharteni Gattolliat & Sartori, 2008, Baetis pacis Yanai & Gattolliat, 2018, and Caenis macrura Stephens, 1835. They are reported and morphologically distinguished from other local relatives. Caenis macrura is widely distributed in the Palaearctic, Ch. soldani and C. vanharteni originated from the Arabian Peninsula, and B. pacis is restricted to a small area in southern Levant. We provide a complete checklist of the Jordanian mayfly fauna and deliver an identification key to the nymphal stages.

This article presents and describesPlantago humboldtiana, an extremely narrow endemic rheophytic new species from a waterfall in Corupá, Santa Catarina state, southern Brazil. The new species is unique in presenting a combination of type-G antrorse trichomes on scapes, pendulous inflorescences and 1-seeded pyxidia. Only one population is known to exist, despite intensive search efforts in nearby, similar environments. Its conservation status is assessed as critically endangered (CR) as the only known population is restricted to a dramatically small area, and is subject to extreme fluctuation due to occasional floods, and also to intense visitation by tourists, which can disturb its fragile habitat. We also present an updated identification key to the species ofPlantagothat occur in Santa Catarina. The recent description of three narrow endemic, threatened new species ofPlantagoin Santa Catarina, which is the Brazilian state with its flora best studied, highlights the need for more taxonomic research, especially in the neotropics.

Species Taxonomy

The carabids of the tribe Platynini from the southern Levant (Egypt: Sinai Peninsula, Israel, Jordan) and adjacent regions of Egypt, Lebanon, Syria, Iraq, and Saudi Arabia are reviewed in terms of species taxonomy, ecological, distributional traits, and conservation biology. In addition to a classical dichotomous identification key to the 14 species of the region, identification tools are made freely available via the Xper3 knowledge database “Platynini, southern Levant”. Besides an interactive identification key, a matrix with character states for the species and single access identification keys are available. A database including all available records from the southern Levant is also provided. First faunistic records are recorded for Anchomenus dorsalis infuscatus from Sinai (Egypt), Olisthopus fuscatus from Lebanon and Iraq, and for O. glabricollis from Iraq. Threatened species are discussed, also with regard to the reasons of their decline. The majority of species lives in wetlands, especially on the shore of winter ponds and streams, which have been extremely degraded in the last decades.

Mascarene Islands

An intertidal survey of 34 sampling stations on the main Mascarene Islands of La Réunion, Mauritius and Rodrigues, was conducted between 2015 and 2018. Results of the survey revealed five species of Tethininae, viz. Afrotethina aurisetulosa (Lamb), Dasyrhicnoessa ferruginea (Lamb), D. insularis (Aldrich), D. vockerothi Hardy & Delfinado and Pseudorhicnoessa rattii Munari, all of which are new to one or more of the Mascarenes (A. aurisetulosa, D. ferruginea and D. insularis new to all three islands; D. vockerothi new to Mauritius and Rodrigues; and P. rattii new to Rodrigues). Sampled species exhibit a very close affinity with those that occur on Seychelles and the composition of the two faunas is notably superimposable. The distributions of the five species on the three main islands is mapped and an identification key to all genera and species of both archipelagos is provided, with the most significant diagnostic features illustrated. The survey also revealed that the rather common Afrotropical genus Horaismoptera Hendel, which is represented in East Africa, Madagascar, and the southern Arabian Peninsula by H. vulpina Hendel, is most likely absent from both archipelagos.

The subgenus Pseudomegachile Friese of the large genus Megachile Latreille is revised for the Western Palaearctic region, Iran, and the Arabian Peninsula. Twenty species are recognized, of which five are new: Megachile blepharis Dorchin & Praz from Israel, M. plumigera Dorchin & Praz from Oman and the United Arab Emirates, M. syriaca Dorchin & Praz from Syria and Turkey, M. yezidica Dorchin & Praz from Turkey and Iran, and M. maxschwarzi Dorchin & Praz from Iran and Central Asia. The following new synonymies are proposed: M. inermis Radoszkowski 1893 (as well as the replacement name M. mitis Cockerell 1899), M. albifasciata Rebmann 1970 and M. transgrediens Rebmann 1970 are placed in synonymy with M. saussurei Radoszkowski 1874; M. tuberculata Radoszkowski 1893 (as well as the replacement name M. tuberculosa Dalla Torre 1896) is placed in synonymy with M. seraxensis Radoszkowski 1893; M. rubripes Morawitz 1875 and M. persica Rebmann 1972 are placed in synonymy with M. flavipes Spinola 1838; M. stolzmanni Radoszkowski 1893 and M. flavidula Rebmann 1970 are placed in synonymy with M. tecta Radoszkowski 1888. Lectotypes are designated for M. cinnamomea Alfken 1926, M. nilotica Pérez 1897, M. inermis, M. seraxensis, M. tuberculata, M. farinosa Smith 1853, M. derasa Gerstäcker 1869, M. erythrocnemis Alfken 1930 and M. xanthocnemis Alfken 1938. An identification key is provided, a phylogenetic hypothesis including most species in the subgenus is presented, and the biology of the species is briefly summarized.

Scanning Transmission

The theory and practical limitations of micro area scanning transmission electron diffraction (MASTED) will be presented. It has been demonstrated that MASTED patterns of metallic thin films from areas as small as 30 Åin diameter may be obtained with the standard STEM unit available for the Philips 301 TEM. The key to the successful application of MASTED to very small area diffraction is the proper use of the electron optics of the STEM unit. First the objective lens current must be adjusted such that the image of the C2 aperture is quasi-stationary under the action of the rocking beam (obtained with 40-80-160 SEM settings of the P301). Second, the sample must be elevated to coincide with the C2 aperture image and its image also be quasi-stationary. This sample height adjustment must be entirely mechanical after the objective lens current has been fixed in the first step.
