Abstract

The Transsylvanian wingless groundhopper, Tetrix transsylvanica (Bazyluk et Kis, 1960) is a flightless pygmy grasshopper (Orthoptera: Tetrigidae) known only from a few fragmented localities and thus considered an endangered (EN) species in the IUCN Red List. The species consists of two subspecies, the nominal T. t. transsylvanica inhabiting the southern Carpathians in Romania, and T. transsylvanica hypsocorypha Skejo, 2014, until now known from a single locality in Slovenia (Mt Boč) and a single locality in Croatia where it was caught last time in the 1940s in Hrvatsko Zagorje (Gornja Pačetina, Trnovec). It is possible that the two subspecies represent separate species. The species has been considered extinct in Croatia. In this paper, we report the discovery of several subpopulations in Croatia, the largest one being at Siljevec on Ivanščica mountain. In addition, small subpopulations are reported on three other mountains (Strahinjčica, Medvednica and Zelinska gora), and two of them are suspected to be under threat of extinction: the subpopulation on the peak of Medvednica, Sljeme, and the subpopulation on Strahinjčica. The latter was discovered in a proximity of a quarry. The species is a (Pleistocene) relic and may be the only groundhopper endemic to Central Europe. Herewith, we appeal for its inclusion in the Ordinance on Strictly Protected Species of the Republic of Croatia, and for T. transsylvanica to be proposed as a candidate for the list of species protected through the Habitats Directive.

濒危的Transsylvanian无翼跳鼠（Tetrix transsylvanica）在克罗地亚尚未灭绝，需要紧急保护

Transsylvanian无翼地蚱蜢，Tetrix transsylvanica（Bazyluk et Kis，1960）是一种不会飞的侏儒蚱蜢（直翅目：蚱蜢科），仅在少数零星地区已知，因此在国际自然保护联盟红色名录中被视为濒危物种。该物种由两个亚种组成，一个是居住在罗马尼亚喀尔巴阡山脉南部的名义T.T.transsilvanica，另一个是T.transsilvanica-hypsocorypha-Skejo，2014年，直到现在，斯洛文尼亚的一个地区（Mt Boč）和克罗地亚的一个地方才知道它，上一次是在20世纪40年代在Hrvatsko-Zagorje（Gornja Pačetina，Trnovec）捕获的。这两个亚种可能代表不同的物种。该物种在克罗地亚被认为已经灭绝。在这篇论文中，我们报告了在克罗地亚发现的几个亚群，其中最大的一个是在伊凡什奇卡山上的Siljevec。此外，据报道，在其他三座山（Strahinjčica、Medvednica和Zelinska-gora）上也有小的亚群，其中两座被怀疑面临灭绝威胁：Medvednic、Sljeme峰上的亚群和Strahinjćica峰上的亚群。后者是在一个采石场附近发现的。该物种是（更新世）的遗迹，可能是中欧唯一特有的地鼠。在此，我们呼吁将其列入《克罗地亚共和国严格保护物种条例》，并建议将特西瓦尼卡作为《栖息地指令》保护物种名单的候选物种。
