Plectrocnemia idsukachevae Melnitsky, Ivanov & Perkovsky sp. n. https://zoobank.org/ urn:lsid:zoobank.org:act: 485BD28B-BD3C-44AC-B1B6-0F94C1644E9D (Figs 4, 5, 6 E) Type material: Holotype. Male. SIZK UA –28033, Rovno amber, late Eocene. Description. Body length 4.1 mm; forewing length 5.1 mm. Head, antennae, wings and thorax brown, legs, abdomen light brown. Male genitalia. Inferior appendages rounded on posterior view with dorsal subbasal projections. Superior appendages sclerotized and elongate, with rounded apices. Segment X with 2 soft lobes; ventral projections of this segment are visible as curved upwards. Small club-like projection with setose tip is visible right side of aedeagus. The aedeagal structures look deformed: soft aedeagus with apical notch and 2 thin lateral spines turned upwards and shifted to the right; two sclerotized rods make V-shaped construction with furrow-like profile supposedly served as ventral support for aedeagus, are seen turned to the left. Comparison. This new species is related to Plectrocnemia nastigermania Melnitsky et Ivanov, 2013 from Rovno amber differing from it in shorter non-pointed superior appendages and in longer thick ventral projections of segment X. Etymology. In honor of the 85th anniversary of paleoentomologist Irina Dmitrievna Sukacheva. Distribution. Priabonian Rovno amber. New findings of previously described species follow.
