Abstract
Psallus (Psallus) thomashenryisp. n. (Hemiptera: Heteroptera: Miridae: Phylinae: Phylini: Phylina) is described from southern Anatolia, Turkey. Illustrations of the dorsal habitus and male genitalia are provided. Its habitus is similar to other uniformly orange species of the subgenus Psallus Fieber, 1858, particularly P.asthenicus Seidenstücker, 1966 from which it can be easily distinguished by the combination of extremely small size (2.3 mm in both sexes) and different morphology of the vesica. Psallus (Psallus) lucanicus Wagner, 1968 is recorded for the first time from Turkey. Psallus (Psallus) aurora (Mulsant & Rey, 1852) is removed from the list of Turkish fauna based on a reevaluation of the voucher specimen. An updated checklist of the species of Psallus known to occur in Turkey is provided. The relevance of Anatolia and the Syro-anatolian-transcaucasian region in the Palearctic distribution of Psallus is discussed. The westernmost record of another mirid, Plagiognathusmarivanensis Linnavuori, 2010, is provided.
Highlights
Psallus is currently subdivided into eight subgenera based on similarities in habitus and male genitalia: Apocremnus Fieber, 1858, Calopsallus Yasunaga & Vinokurov, 2000, Hylopsallus Wagner, 1952, Mesopsallus Wagner, 1970, Psallus Fieber, 1858, Phylidea Reuter, 1899, Pityopsallus Wagner, 1952, and Supsallus Linnavuori, 1993 (Kerzhner and Josifov 1999, Yasunaga and Vinokurov 2000, Yasunaga 2010)
As a result of this study, a total of 36 species of Psallus are confirmed to occur in Turkey, as detailed in the following updated checklist
The total number of 36 species is comparable to the number of species of Psallus occurring in other northern Mediterranean countries such as France (31) or Italy (34), but with an important difference in the percentage of endemic species
Summary
The predominantly Palearctic genus Psallus Fieber, 1858, including 160 valid speciesgroup taxa, is one of the most speciose in the subfamily Phylinae (Schuh 1995, 2013; Kerzhner and Josifov 1999; Yasunaga 2010; Matocq 2011; Duwal et al 2012; Vinokurov and Luo 2012; Aukema et al 2013; Li and Liu 2013; Schuh et al 2014; Simon and Strauss 2014; Konstantinov 2016; Pagola-Carte 2017). 34 species of Psallus were known to occur in Turkey. The West-Mediterranean Psallus (Psallus) aurora (Mulsant & Rey, 1852) is removed from the list of Turkish fauna based on a reevaluation of the voucher specimen
