We had a great deal of really excellent articles for this issue, so many thanks to all who contributed. In addition to our Facebook page where we can keep members updated, we now also have a webpage hosted by the IUCN containing further information about our group and some of the activities we have participated in, as well as featuring some species of Orthoptera and related taxa that are of interest to the conservation community. Since 2013 the group has been very active, with one of our first activities being a red-listing workshop held in Leiden, the Netherlands focusing on the European Orthoptera. This led to the first major update of the Orthoptera in November 2013 with 60 new species being added to the IUCN Red List. By May 2014 we have now assessed a total of 337 species of Orthoptera, with plans to increase this number continuously over the next few years. As 2014 is the 50th anniversary of the IUCN Red List this is a great opportunity to promote the conservation of Orthoptera. Also, in May 2014 a conservation strategy planning meeting was held in South France for the Crau Steppe Grasshopper, a species recently assessed as Critically Endangered and now the focus of a conservation effort, a report of which is featured in this newsletter. Hopefully this will be the first of many such projects and will help to highlight the importance of this charismatic group of invertebrates. As the group is expanding and becoming more proactive, and with Axel taking over the reins as the Chair of the IUCN Invertebrate Conservation Sub-Committee, it was decided to enlist another co-chair to help keep things running at the pace they are currently, Mark Bushell has accepted this position and hopes to keep the momentum of our group going, with many new activities and projects planned for the coming years. Please keep us informed about new and ongoing conservation projects of Orthoptera and their allies so that we can include these reports in the next Newshopper. Best wishes, Axel Hochkirch & Mark Bushell, Co-Chairs Attendees at the red-listing workshop held in Leiden, the Netherlands, May 2013.

Roberto Battiston & Kai Schütte We don’t have the answer to this question yet, but we’re working on it with the ongoing project European Redlisting of Mantodea. What we know is that research on mantid conservation is becoming more important. After a remarkable disinterest for these charismatic insects during the second half of the last century, within the last few years mantids have become an interesting field of research, including conservation. There are still few specialists working on these insects but the group of experts is steadily growing and what is even better, the cooperation is increasing. One of these joint efforts was recently published (May 2014) in the special issue of the scientific journal Zootaxa (3797), entirely dedicated to mantids, entitled “A revived focus on the praying mantises”. It contains 12 articles from 22 authors, often the result of international collaborations. More interest also means a greater focus on conservation problems - problems we have dealt with in the special issue. Apteromantis aptera (photo – R. Battiston) How diversity influences conservation will be discussed in York at the European Congress of Entomology in August 2014, which will host a symposium entirely dedicated to mantids. It is now more urgent than ever to generate more mentioned special issue of Zootaxa for the Canary interest on mantids and to have more people work on Islands, most probably a hotspot for small range their taxonomy and biology because the main threat endemic Mantodea in Europe. for these insects probably is that we still do not know what the threats consist of. The first two assessments (the update of Apteromantis aptera to LC level, and the new CR/PE For these reasons this spring we made an open call to Ameles fasciipennis) have been just published on the all the GSG specialists to collect new records and IUCN Red-List website, but most of the other provide additional specimens to use in genetic and European species is practically unknown by IUCN morphological analyses to solve at least part of their standards. This can easily result in very misleading problematic taxonomy. Particularly welcome and Data Deficient assessments and thus not proof useful important are specimens from the genera Ameles and for conservation actions and to promote further Pseudoyersinia, two small ground mantids with research. brachypterous females and macropterous or brachypterous males. Their taxonomy is extremely Ameles fasciipennis is a very good example for this: problematic because many species are probably not Being a distinct and well defined single individual, it valid or have to be rearranged, because their appeared only once more than a century ago, then description based on few specimens or few probably disappeared. By IUCN standards this is the morphological characters only or their high degree of rarest animal in the world, by scientific standards it morphological plasticity and the limited knowledge is may be a taxonomical error or a biological deviation, difficult to fit in IUCN criteria. This problematic by conservation standards it is an unmanageable taxonomic state of the art is discussed in detail in the animal. Or, it may really be a species we have lost. 4 GSG Newshopper - August 2014 That is the reason why it is now so important to gain more knowledge about the European Amelinae and to work towards their conservation needs. We are thankful for two grants from SYNTHESYS that allow us to work in the collections at the Natural History Museum in London and the National Museum of Natural Sciences in Madrid. Both museums have important collections of European mantids, but we are still searching help from other museums to obtain a detailed database of the mantids distribution. We have started to sequence recently collected material, mainly from the Iberian Peninsula and first results are expected soon. Contributions from GSG specialists and friends of these insects would be very helpful and welcome. If you would like to help, please send any collecting information and/or specimens in alcohol 95% to Kai Schütte, Biozentrum Grindel und Zoologisches Museum Dept. Entomology, Martin-Luther-King-Platz 3, 20146 Hamburg, Germany. Thank you! Roberto Battiston ([email protected]) & Kai Schütte ([email protected]) Heterochaeta orientalis - the cat mantis.

He didn’t find any How grasshoppers help Sphingonotus, but he did find Oedipoda discovering new species in caerulescens, of which he took a few pictures. Looking at the photos at home he discovered a the Netherlands small striped creature near the front leg of the grasshopper. Matty Berg, a springtail specialist, Roy Kleukers was highly surprised. It turned out to be Fasciosminthurus quinquefasciatus, a new species On July 23, 2013 nature photographer André den to the Netherlands. This proves that looking at Ouden was looking for Sphingonotus caerulans grasshoppers can be even more rewarding than near the city of Nijmegen. This species was we thought. The new species has been given the recently discovered in the Netherlands, but seems appropriate common name zebra springtail.

Bazelet, Department of Conservation Ecology and Entomology, Stellenbosch University, Private Bag X1, Matieland 7602, SOUTH AFRICA. In 2014, 129 species of South African katydids (Tettigoniidae) will have Red-List assessments published by the IUCN. These species represent approximately three-quarters of the katydid species known to occur in South Africa (169 species in total), and the full complement of species which are currently capable of being assessed. Of the unsuitable species, seven are recognized new species which await formal description, and 33 are species or subspecies whose validity requires verification such as members of the problematic genera Ruspolia and Conocephalus, many of which can be distinguished only on the basis of their call, and are in need of taxonomic revision on the basis of this character (Fig.
