Eurygaster testudinaria (Geoffroy, 1785)

Throughout the study area collected in large numbers.

SUMMARY AND DISCUSSION

In the research area a total number of 71 species of Heteroptera were collected. They proved to belong to 8 different families: Anthocoridae (2 species), Nabidae (7 species), Miridae (45 species), Tingidae (4 species), Rhopalidae (5 species), Berytidae (6 species), Rhyparochromidae (1 species) and Scutelleridae (1 species). Almost half of them, 34 species, were recorded for the first time in Pieniny Mts. First records of very common Polish species in the study area (e.g. Deraeocoris ruber , Chlamydatus pulicarius , Criocoris crassicornis , Plagiognathus arbustorum , P. chrysanthemi , Lygus rugulipennis and Stenodema calcarata ) ( Gorczyca 2007, Gorczyca & Wolski 2011) prove the still insufficient knowledge of the heteropterofauna of Pieniny Mts. It should be noted that some of these species were probably previously collected on the area of Pieniny Mts, but due to their commonality, the authors did not provide detailed data on their collecting sites, e.g. Smreczyński (1954).

Some of the recorded true-bugs are rarely collected in Poland: e.g. thermophilic species of southern type of range ( Adelphocoris detritus : Fig. 6A , Criocoris nigripes : Fig. 6B , Eurycolpus flaveolus and Berytinus signoreti ), as well as mountain species ( Macrotylus quadrilineatus , Stenodema sericans , Berytinus signoreti and Lygus wagneri ) ( Gorczyca 2007, Gorczyca & Wolski 2011, Taszakowski 2016). Occurrence of thermophilic species of southern type of range in Pieniny Mts may be associated with an immigration via the Spisz migratory route. During the immigration, the habitats that formed on the warm slopes of the valley of the Dunajec River could be used ( Mazur 2001, Taszakowski 2015).

A notable species is Eurycolpus flaveolus , which has not been recorded since 1910. In Poland it is known exclusively from Pieniny Mts. The species was included in the Polish Red book of animals, with the status "probably extinct" ( Gorczyca 2004b).
