Lecanopsis

Pellizzari, Giuseppina, 2013, Three new species in the subfamily Eriopeltinae Šulc from Italy (Hemiptera, Coccoidea, Coccidae) with comments on the genus Lecanopsis, Zootaxa 3635 (2), pp. 101-116 : 112-113

Key to adult female Lecanopsis

The key omits L. iridis , whose adult female is unknown. Descriptions and redescriptions of L. aphenogastrorum , L. shutovae , L. taurica and L. myrmecophila are based on the only one or two adult females of the type series, often in bad condition, so that their intraspecific variability is not known. The above reported species have not been recorded since their description (see Pellizzari & Fontana, 2002, for details).
