Abstract: The genus Dicyphus Fieber, 1858 (Miridae: Bryocorinae: Dicyphini) comprises
small plant bugs well known for their zoophytophagous diet and predatory
activity, making them useful in biological control. Despite their importance in
plant protection, many species remain difficult or impossible to identify. This
is the case of both species Dicyphus (Dicyphus) bolivari Lindberg, 1934 and
Dicyphus (Dicyphus) tamaninii Wagner, 1951, commonly found in vegetable crops in
Western Europe. We have conducted a taxonomic study integrating morphological
(including male and female genitalia), molecular, biogeographical, and
biological data. The following new synonymy is proposed: Dicyphus bolivari
Lindberg, 1934 = Dicyphus tamaninii Wagner, 1951, syn. nov. The synonymies
established by Sanchez & Cassis (2018), Dicyphus bolivari Lindberg, 1934 =
Dicyphus bolivari atlanticus Wagner, 1951 = D. marocca- nus Wagner, 1951, are
confirmed. Dicyphus bolivari is compared to closely related species. The
following country records are added to D. bolivari range: Channel Islands:
Guernsey, Italy: Sardinia, Monaco, Asian part of Turkey and Cyprus.
