Annotated red list of Symphyta of the Carpathian Basin

Annotated red list of Symphyta of the Carpathian Basin In the Carpathian Basin, the nature conservation status of threatened Symphyta is poorly known, although the faunistic researches started approximately 240 years ago. The endangerment evaluation in the previous studies is frequently subjectivized, based on limited data and do not comprising all taxa. For instance, although in the former Czechoslovakia the Red book of Invertebrata has been published in 1992, only two species Rhadinoceraea reitteri Knw. and Cephus pulcher Tischb. were listed there, only as examples of numerous endangered Symphyta (BENES 1992). The present red list of Slovak Hymenoptera contains about 100 vulnerable and endangered Symphyta species (LUKAS 2001). On the other hand, there is no Syphyta species on the national red lists of the other countries of the Carpathian Basin. Our list of faunistic records helps us to have better view on the natural conservation status of rare Symphyta. These rare species with restricted distribution area in the Carpathian Basin or associated with threatened foodplants are analyzed hereunder. In most cases, the reasons of their local and random occurrence are still unknown. These species were evaluated as data deficient (DD) taxa since: 1. their biology and especially foodplants are unknown, 2. they are taxonomically problematic species or 3. they are probably extremely rare (single, frequently even historical records from the Carpathian Basin). Several species are documented in the studied area by single and/or historical or even indefinite records. Actual occurrences of these species in the Carpathian Basin need confirmation. The reidentification of old material was not always possible. Faunistic investigation of the endangered species is the task of future Symphyta research. Species documented by indefinite faunistic records (like: NE. Croatia, Croatia, Hungary, Slovakia) are not evaluated or mentioned in the red list below. On the other hand, we provide data on number and sex of collected specimens and collection date of the evaluated sawflies. The nature protection status of these species differs from those listed in the previous studies. Many vulnerable species from the red list of Slovak Hymenoptera (LUKÁS 2001) were replaced into the "data deficient" group or into not threatened species. Good example is Rhadinoceraea reitteri Knw., that is restricted to few xerothemous localities in Slovakia but widely distributed in Hungary, thus it was not evaluated hereunder. This extensive list of faunistic records on Symphyta may help to prepare more objective red lists in national or even European level. Abbreviations: EX-extinct, EN - endangered, VU- vulnerable, DD - data déficient Xyelidae Xyela longula Dalman, 1819: Single record near the western border of the Carpathian Basin: Hohe Wand (Austria) Evaluation: EN Pleroneura coniferarum (Hartig, 1837): We have mainly indefinite data. One female with locality label "Hungary" in the Budapest collection. Known localities only Drohobycz (Poland), Kojetín u Val. Mezifící (Czech Rep.) and Fuzine (Croatia). Evaluation: EN Pleroneura dahlii (Hartig, 1837): Most of our data are indefinite (Slovakia, West Beskid Mts., Hungary). One female in the Budapest collection with locality label "Hungary". Other known localities from Moravian Carpathians: Trojacka, Jicina, Skalice. Evaluation: EN Comments: The food plant of Pleoneura spp., Abies alba, is also threatened in the Carpathian Basin.
