description
Genetic data. Nearest COI barcode neighbour is E. purpureae, with about 4.3 % divergence. Similar species. Resembles E. nitidinota in external morphology. The lancets (E. nudipectus, Fig. 38; E. nitidinota, Fig. 39) are also very similar, except that the distal cypsellae are deeper and more rounded in E. nitidinota. Bionomics. Host plants: Salix phylicifolia (Kopelke 2007 c, Vikberg 2010 b). Biology: Vikberg (2010 b), Zinovjev & Vikberg (1999).

Similar species. Resembles E. nudipectus in external morphology. The lancets (E. nudipectus, Fig. 38; E. nitidinota, Fig. 39) are also very similar, except that the distal cypsellae are shallower and less rounded in E. nitidinota. Bionomics. Host plants: Salix phylicifolia is definitely a host, but possibly other willow species may also be used (Vikberg 2010 b). Biology: no data available.
description
Variability. Female: Body length: 3.4 – 5.2 mm. Male: 3.5 – 4.2 mm. Total number of specimens examined: 15. Genetic data. The COI barcode of the only sequenced specimen of E. cyrnea (paratype from Corsica) shares the same BIN as five E. purpureae from Austria, France, and Morocco. Nevertheless, divergence of E. cyrnea from the nearest E. purpureae amounts to about 1.9 %. Bionomics. Host plants: Salix caprea (Kopelke 2007 c, Vikberg 2010 b). Biology: Beneš (2015 a), Vikberg (2010 b), Zinovjev & Vikberg (1999: as joergenseni). The galls illustrated by Mol (2013: fig. 6) were definitely not caused by E. cyrnea: they show the characters typical of the ischnocera complex of the E. oblita group.
