The singing cicadas (Auchenorrhyncha: Cicadoidea) of Bulgaria remain poorly known. There are published records for 14 species (Arabadzhiev 1963, Barjamova 1976, Barjamova 1978, Barjamova 1990, Dirimanov and Harizanov 1965, Dlabola 1955, Gogala et al. 2005, Háva 2016, Janković 1971, Nast 1972, Nast 1987, Nedyalkov 1908, Pelov 1968, Yoakimov 1909): Lyristes plebejus, Cicada orni, Cicadatra atra, C. hyalina, C. persica, Cicadetta montana, C. mediterranea, Oligoglena tibialis, Tympanistalna gastrica, Pagiphora annulata, Dimissalna dimissa, Saticula coriaria, Tibicina haematodes and T. steveni. Two species from this list should be excluded from the list of Bulgarian cicadas, since T. gastrica is distributed in central and southern Portugal (Sueur et al. 2004) and S. coriaria is a north African species (Boulard 1981). We checked three major institutional collections housed in Sofia, Bulgaria: the National Museum of Natural History (NMNHS), Institute of Zoology (ZISB) and Biology Faculty of Sofia University "St. Kliment Ohridski" (BFUS). We confirmed 11 of the species mentioned in the literature, except C. mediterranea, and found 2 additional species: C. brevipennis and C. macedonica. Based on this knowledge, we further investigated the singing cicadas of Bulgaria with the use of classical and bioacoustic methods in the years 2008, 2009, 2010, 2012, 2016, 2018 and 2019. We were not able to confirm the presence of C. persica and C. mediterranea, but found three additional species: Cicadatra platyptera, Cicadetta cantilatrix and Tettigettula pygmea. Using the bioacoustic methods we also detected 3 to 4 additional taxa, which need to be described. Thus, the Bulgarian fauna of singing cicadas at the moment consists of 17+ species.

The singing cicadas (Hemiptera: Cicadidae) of Bulgaria were poorly known. There are published records for 14 species: Cicada orni, Lyristes plebejus, Cicadatra atra, Cicadatra hyalina, Cicadatra persica, Cicadetta montana, Cicadetta mediterranea, Dimissalna dimissa, Oligoglena tibialis, Tympanistalna gastrica, Pagiphora annulata, Saticula coriaria, Tibicina haematodes and Tibicina steveni. Two species from this list were doubtful in the beginning of our study, since Tympanistalna gastrica is distributed in central and southern Portugal and Saticula coriaria is a north African species. We checked three major institutional collections housed in Sofia, Bulgaria: the National Museum of Natural History (SOFM), the Institute of Zoology (ZISB) and the Biology Faculty of Sofia University "St. Kliment Ohridski" (BFUS). We confirmed 11 of the species mentioned in literature, except Cicadetta mediterranea and found two additional species: Cicadatra platyptera and Cicadetta macedonica (the specimens in BFUS were bioacoustically confirmed). Based on this knowledge, we further investigated the singing cicadas of Bulgaria with the use of morphological and bioacoustic methods in the years 2008, 2009, 2010, 2012, 2016, 2018 and 2019. We were not able to confirm the presence of Cicadatra persica and Cicadetta mediterranea, but found three additional species: Cicadetta brevipennis s. lat., Cicadetta cantilatrix and Tettigettula pygmea. Using the bioacoustic methods, we also detected unknown singing patterns, which could belong to three or four additional taxa, which need to be described. The Bulgarian fauna of singing cicadas at the moment consists of 16 confirmed and 3-4 potential species.

A Collection of ticks from British Somaliland recently sent to the British Museum (Natural History) contained specimens of a species of Ornithodoros unlike any in the national collection and (from the appearance of the integument) related to the North African species O. foleyi Parrot (from Algeria) and O. delanoëi Roubaud & Colas-Belcour (from Morocco). The late Prof. G. H. F. Nuttall presented to the Museum a specimen of O. foleyi, and the writer is indebted to Prof. E. Roubaud for comparing one of the present specimens with the type of O. delanoëi. Prof. Roubaud writes to say that, having examined the Somaliland specimen, he and M. Colas-Belcour are of the opinion that it belongs to the species O. delanoëi: and that the various details of structural difference do not warrant a specific distinction, but indicate that the present specimens may belong to a different biological or geographical race. The large size of these Somaliland ticks, the discovery of their larvae and their presence in a locality so widely separated from that of the type, are considered important enough to be placed on record, and the specimens are regarded as representing a subspecies of O. delanoëi

The Mediterranean basin is known to be the cradle of many endemic species. Within mayflies (Insecta, Ephemeroptera), North African species belonging to the family Baetidae remain poorly known and, traditionally, affinities to European fauna were proposed. Recent studies, based on molecular reconstructions, showed closer relationships to Mediterranean islands fauna. Baetidae were sampled from North-West Algerian wadis (Tafna basin) and involved in COI barcoding reconstructions. Seven species were identified. The subgenus Rhodobaetis is represented by Baetis atlanticus known previously from Macaronesian islands, Europe and Morocco and the Maghrebian endemic Baetis sinespinosus. Specimens, previously identified as Cloeon cf. dipterum, correspond to Cloeon peregrinator and, until now, only reported from Macaronesia. Besides the confirmation of endemicity of some species, such as Procloen stagnicola and B. sinespinosus, our molecular study showed quite original results for relationships between European, insular and Algerian species. Baetis maurus stood out as a North African endemic sister clade to an Iberian clade. Furthermore, we found clear interspecific distances between Algerian and European clades for A. cf. sinaica and B. cf. pavidus, suggesting the presence of cryptic species in Algeria. However, additional studies are needed, as, for the moment, no clear morphological characters were found to separate the different clades and support them as valid species.

In this retrospective piece, the Guest Editor of the first number of CounterText (a special issue titled Postcolonial Springs) looks back at the past five years from various scholarly and personal perspectives. He places particular focus on an event that took place mid-way between the 2011 uprisings across a number of Arab countries and the moment of writing: the March 2015 terror attack on the Bardo National Museum in Tunis, which killed twenty-two people and had a profound effect on Tunisian popular consciousness and that of the post-2011 Arab nations. In this context, the author argues for a renewed perspective on memoir as at once a memorial practice and a political gesture in writing, one that exceeds concerns of genre and form to encompass an ongoing project of political re-cognition following events that continue to remap the agenda for the region. The piece makes a brief final pitch for Europe's need to re-cognise, within those modes of ‘articulacy-in-difficulty’ active on its southern borders, specific answers to its own present quandaries.

AbstractThe genus Folsomides Stach, 1922 is redefined and given a narrow definition based on a limited set of consistent morphological characters: Position and distribution of tergal macrosensilla, chaetotaxy of mouth region, tibiotarsi, ventral tube and furca. Eighteen new species are described from the Canary Islands: semiparvulus sp. n., xerophilus sp. n., vinosus sp. n., cumbrosus sp. n., unicus sp. n., terrus sp. n., pocosensillatus sp. n., nigrocellatus sp. n., teno sp. n., oromii sp. n., ononicolus sp. n., graminis sp. n., famarensis sp. n., pinicolus sp. n., intermedius sp. n., tonellus sp. n., supranubius sp. n. and analuisae sp. n. The following European/African species are redescribed: parvulus Stach, portucalensis Gama, angularis (Axelson), cf. petiti Delamare, lawrencei Gers & Deharveng, cf. zairensis Martynova, nanus Ellis and centralis (Denis). Highly discriminate species characters are found in maxillary palp, tibiotarsal chaetotaxy and distribution of tergal microsensilla. A number of species are removed from Folsomides, and Subisotoma Stach, 1947 is given generic rank.
