The tribe Halyini Amyot & Serville, 1843 (Hemiptera: Heteroptera: Pentatomidae) which has been represented in Turkey so far by 6 species from 3 genera is reviewed and identification keys, morphological figures and the distributional patterns in Turkey and Palaearctic region of the formerly determined species (Carenoplistus acutus (Signoret, 1880), Apodiphus amygdali (Germar, 1817), Mustha spinosula (Lefebvre, 1831), M. longispinis Reuter, 1890, M. izmirensis Memon & Ahmad, 2008) as well as of two new records (Apodiphus integriceps Horvath, 1888 and Mustha vicina Hoberlandt, 1997) are given. The possibility of introduction of A. integriceps to Turkey with plant saplings and thus its alien status is discussed. Previously recorded M. incana Stal, 1876 in Turkish Heteroptera fauna is proved to be actually M. vicina and therefore M. incana is excluded from the faunal list of the Turkish Heteroptera. Furthermore, the distribution of the tribe Halyini in Turkey was presented by ascertaining the exact identification of some species given with wrong information in previous studies.
