Hvar Saw Bush-cricket Barbitistes kaltenbachi Harz, 1965 (Phaneropterinae: Barbitistini) and Lesina Bush-cricket Rhacocleis buchichii Brunner von Wattenwyl in Herman 1874 (Tettigoniinae: Platycleidini) are flightless orthopterans restricted to a narrow area in the Mediterranean part of Croatia, both originally described from Hvar Island. In this study, all available information on these two interesting species is presented: data on morphology, bioacoustics, distribution, habitat, and a key to identification of the species belonging to genera Barbitistes and Rhacocleis in Croatia. The songs of both B. kaltenbachi and R. buchichii are described here for the first time, with the former one being the second known example of a synchronising and presumably duetting species. Both species were reassessed according to the IUCN Red List criteria, where B. kaltenbachi should be considered an endangered species, while R. buchichii is suggested to be downgraded to a less threatened category. Biogeography and evolution of the species are briefly discussed.

The first annotated checklist of crickets and grasshoppers (Orthoptera) of Croatia is presented. With 184 orthopteran species, 103 Ensifera and 81 Caelifera, known to inhabit the country, Croatia is among the richest European countries in terms of Orthoptera diversity. Altogether 25 species erroneously reported from the country are omitted from the checklist, 16 Ensifera (Isophya speciosa, Poecilimon brunneri, P. jonicus, P. thoracicus, Modestana ebneri, Pachytrachis bosniacus, Rhacocleis neglecta, Tessellana carinata, T. nigrosignata, Zeuneriana marmorata, Pteronemobius lineolatus, Myrmecophilus acervorum, M. ochraceus, Dolichopoda palpata, Diestrammena asynamora, Troglophilus brevicauda) and 9 Caelifera (Tetrix kraussi, Paracaloptenus caloptenoides, Chorthippus albomarginatus, Omocestus viridulus, Pseudochorthippus montanus, Miramella alpina, Celes variabilis, Oedipoda germanica, O. miniata). First faunistic records of 10 taxa are reported for Croatia, in total four Ensifera (Leptophyes punctatissima, Metrioptera hoermanni, Zeuneriana amplipennis, Gryllotalpa sp.) and six Caelifera (Xya variegata, Chorthippus dichrous, C. loratus, C. mollis ignifer, Odontopodisma sp., Acrotylus l. longipes). For each listed species, its distribution in Croatia and in Europe is given, and IUCN European Red List status is shown for species within threatened categories. Numerous distributional, taxonomic and nomenclatural problems are discussed. Several taxa with poorly defined diagnostic traits are synonymized, namely Gampsocleis abbreviata renei syn.nov. (with G. a. abbreviata), Pholidoptera maritima syn.nov. (with P. dalmatica), P. brachynota syn.nov. (with P. dalmatica), Acrida m. mediterranea syn.nov. (with A. u. ungarica), Chrysochraon dispar intermedius syn.nov. (with C. d. giganteus) and Odontopodisma rammei syn.nov. (with O. fallax).

When considering the anthropogenic pressure, the orthopterans are among the most important invertebrate groups used for environmental monitoring. In order to effectively manage their conservation, it is imperious to have a clear understanding of their ecological requirements and geographic distribution. The Balkan Peninsula is an area with various complex habitats, supporting a rich Orthoptera fauna, with numerous endemics. Many of these habitats are yet unexplored and can still yield surprises. Within the past years, during our field campaigns in the Balkan Peninsula, we found new populations of several overlooked species from the genera Poecilimon, Pholidoptera, Eupholidoptera, Myrmecophilus, Stenobothrus etc. Thus, we are discussing the IUCN Red List conservation status in some of these, based on our new data.

The Red List is meanwhile published, but new information constantly arises and some colleagues have already spotted errors. We will not change any minor errors immediately, but we have created a Google Sheet, in which we collate all necessary changes that need to be implied during the next update. So, if you spot any errors or if you have new information on species, please do not hesitate to send it to Axel Hochkirch, Baudewijn Odé, Luc Willemse or Roy Kleukers. However, if you feel that new information points to a higher threat level of a species, we may re-assess it earlier.

The Carpathian Mountains, particularly the Eastern Carpathians, represent an area with a high diversity and endemism in grasshoppers and bush-crickets. The well-preserved mountain grassland habitats are populated by diverse orthopteran assemblages. During the second half of July 2013, we visited 24 sites in Romanian Carpathians within altitudes ranging from 237 to 1700 m a.s.l. and found 71 Orthoptera species (36 Ensifera and 35 Caelifera). These represent 37.3% of the 190 species known to occur in Romania. Nine Carpathian endemics (Isophya stysi, Pholidoptera frivaldskyi, Pholidoptera transsylvanica, Miramella ebneri, Pseudopodisma transilvanica, Isophya harzi, Isophya nagyi, Isophya sicula, Zubovskya banatica), of which the last four are endemic to Romania and Eastern Carpathians, were recorded. Four environmental characteristics, i.e. habitat type, altitude, mean temperature and precipitation on sampled sites, are used to examine the structure of orthopteran assemblages by using DCA. Also, more detailed information on the occurrence of rare and endemic species is given.
