161 Euura renei ( Lindqvist, 1958)

Fig. 157

Pteronidea renéi Lindqvist, 1958: 104 . Holotype ♀ not found in NHRS. Type locality: Sweden, Torne Lappmark , Torneträsk. DEI-GISHym12067 is almost identical to a paratype http://id.luomus.fi/GL.5235.

Diagnosis

Most similar to E. lienterica , E. pravus , E. reticulata , and E. serela sp. nov. Sutures of the lancet tend to be somewhat S-shaped in E. lienterica , but are more or less straight in E. renei . Median mesoscutal lobe has a large triangular black fleck in E. pravus and E. serela , but is completely or nearly completely pale in E. renei . Black antennae in E. pravus can further help to distinguish it from E. renei (ventrally pale). Euura reticulata is usually darker and smaller than E. renei , but can be of similar size and colouration, in which case the head shape (antero-posteriorly contracted E. reticulata ) could help to separate the species. 6.0– 6.8 mm; antennae as long as costa or shorter; lamnium 2.8–2.9 times as long as radix.

Host plants

Perhaps Salix lapponum , if the reared specimen PR.607 VV is conspecific with DEI-GISHym12067.

Genetics

COI

Only one sequence available. The nearest neighbour, diverging by a minimum of 0.15%, is Euura flavescens .

Nuclear

Only one sequence available, a female with haplotypes diverging by 0.27%. The nearest neighbour, diverging by a minimum of 0.75%, is Euura seriepunctata .

Distribution and material examined

Palaearctic. Specimens studied are from Finland (if the specimen PR.607VV reared from Salix lapponum is correctly identified), Norway, and Sweden.
