Notes

In accordance with Article 23.9.1 of the International Code of Zoological Nomenclature ( ICZN 1999), we retain the junior name poecilonota as valid, because it has been used more than 25 times by at least ten authors as the valid name for this taxon during the last 50 years, whereas continuus has not been used as valid since 1899. Examples of use of poecilonotus or poecilonota as the valid name for this taxon during the last fifty years: Verzhutskii 1981; Kangas 1985; Viitasaari & Vikberg 1985; Liston 1995, 1997; Zhelochovtsev & Zinovjev 1995; O’Connor et al. 1997; Blank & Taeger 1998; Taeger et al. 1998, 2006, 2010; Viitasaari et al. 1998; Lacourt 1999, 2020; Blank et al. 2001; Haris 2002; Roller & Haris 2008; Schedl 2009; Liston et al. 2014; Jansen 2015; Chevin & Savina 2016; Sundukov 2017b; Macek et al. 2020; Prous et al. 2021; Humala 2024.

Diagnosis

Live adult females are green, and most similar to species in the bergmanni and oligospila groups, from which E. poecilonota is best distinguished by its distinctive lancet and penis valve. Antenna black. Males are extremely rare. The larval stage of the hyalinus type was described by Dyar (1895) under the name Nematus lateralis .

Only one male is known (DEI-GISHym12527), confirmed to be this species based on a 207 bp sequence of COI that is identical to some of the females.

Host plants

Betula spp. , but not recorded from B. nana ( Wong 1954; Tenow 1963; Kangas 1985). One generation per year ( Wong 1954). The female cuts characteristic slits in birch leaves and one egg is inserted into the edge of each slit.

Genetics

COI

Based on 8 specimens, maximum within-species distance is 1.37% and the nearest neighbours, diverging by a minimum of 6.23%, are Euura monticola , E. perkioemaekii , and E. sordidiapex .

Nuclear

Based on 6 specimens, maximum within-species distance is 1.64% (0.22% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 2.71%, is Euura frenalis .

Distribution and material examined

Holarctic. Specimens studied are from Canada (only genetics), Estonia, Finland, Germany, Russia, and Sweden.
