This study is based on material of the suborder Heteroptera collected and photographed from different provinces of Turkey between 2011 and 2015. In this study, 15 species belonging to 9 families are recorded from various provinces of Turkey. All of the species listed include remarks on their known distribution either in Turkey or in worldwide. Among them 12 species are new for the Heteroptera fauna of Turkey. In addition it is found out that Pasira marinadolina Putshkov & Moulet, 2003 could also have bicolored connexivum.

This study is prepared to provide an example for the utility of citizen science in faunistic research, which is becoming popular as a data source, especially for invasive alien species. With the globalization tendency of many living species by human impact, alien species rapidly spread far from their natural distribution range and become invasive in their newly settled ecosystems. Some of these invasive alien species become one of the most important problems for nature. This study focuses on distribution of following eight alien Hemiptera species that have previously been recorded from Turkey: Zelus renardii (Reduviidae), Corythucha arcuata and Corythucha ciliata (Tingidae), Leptoglossus occidentalis (Coreidae), Perillus bioculatus and Halyomorpha halys (Pentatomidae), Stictocephala bisonia (Membracidae) and Metcalfa pruinosa (Flatidae). New distributional and seasonality data for all these species are presented based on observations shared by citizen scientists in the websites Doğalhayat and iNaturalist. New provincial records for each species are given. As a result, it is apparent that citizen science is an important data source, supplies remarkable contribution for increasing the understanding on expansion of invasive alien species as well as providing clear picture on their distribution.

The research was based on a short but intensive collecting trip made in April-September 2018-2020. Twenty two species were reported, many firstly recorded for collecting sites. From these species, 1 species belonging to each of the Stenocephalidae, Pyrrhocoridae, Reduviidae, Nabidae, Tingidae, Orsillidae, Artheneidae, Cymidae, Coreidae and Scutelleridae families, 2 species belonging to each Miridae and Lygaeidae (sensu stricto) families, 2 species belonging to Rhopalidae family, 3 species belonging to Pentatomidae family and 3 species belonging to Rhyparochromidae family were obtained. The most of these taxa are new records for these locations.

Abstract In this paper, two new Miridae species are described from Turkey, Adelphophylus oenderi sp. nov. from Silifke (Mersin province) and Phytocoris (Exophytocoris) carapezzai sp. nov. from Merkez (Karaman province). Habitus of males and females and male genitalia of both species and female genitalia of A. oenderi sp. nov. are illustrated. Additionally, 10 Heteroptera species are recorded from Turkey for the first time: Campylomma miyamotoi Yasunaga, 2001, Compsidolon (Compsidolon) elegantulum Reuter, 1899, Hallodapus concolor (Reuter, 1890), Maurodactylus kukuensis V. G. Putshkov, 1978, Pinalitus viscicola (Puton, 1888), Platycranus alkestis Linnavuori, 1999, Zanchius breviceps (Wagner, 1951), Montandoniola moraguesi (Puton, 1896), Temnostethus (Temnostethus) gracilis Horváth, 1907, and Plinthisus (Isioscytus) minutissimus Fieber, 1864. Campylomma miyamotoi Yasunaga, 2001, an Eastern Palaearctic species bound to the ornamental Albizia julibrissin, is a new potentially alien species in the Western Palaearctic. The species status of Compsidolon (Compsidolon) parietariae V. G. Putshkov, 1984 is discussed.
