Recent discoveries of amber deposits have resulted in numerous new caddisfly species of Rovno amber described in a series of recent papers (Melnitsky & Ivanov, 2010, 2013, 2016a, b). The list of species previously known from Rovno amber included 42 species (Ivanov et al., 2016; Perkovsky, 2017). Our study is based on a collection of Trichoptera from a new Rovno amber locality near Olevsk in Zhytomyr region. Nine amber species have been reported from this region (Legalov et al., 2021; Radchenko et al., 2021), including new ant species, a new anthribid, two new genera, and four new species of gall midges (Fedotova & Perkovsky, 2015, 2017); additional new cicadellid genus and species is described from closely connected fauna of Perebrody (Dietrich et al., 2021). It total, the new collection includes 6 pieces of Rovno Amber with six specimens of Trichoptera, two of those are described below as a new species of Electrotrichia.
