146 Euura clitellata group sp. 1

Fig. 374

A single male (ZMUO.035580) from Utsjoki ( Finland) is clearly a different species from the others in the group, based on nuclear DNA. The penis valve is not clearly distinguishable from E. clitellata , but externally (colouration and the projection of tergite 8) it is most similar to E. fallax . Of the North American species treated by Ross (1945), ZMUO.035580 is perhaps most similar (based on the penis valve and the projection of tergite 8) to Euura aurata ( Marlatt 1896a: 91–93, 99–100) ( Pachynematus auratus Marlatt, 1896 ), but the characters do not seem to fit perfectly. The dominant COI variant belongs to BOLD:ACF0333 (most European E. clitellata specimens), the second to BOLD:ACM0632 (North America) and the third is closest (2.4%) to BOLD:ABX5515 (North America and some secondary variants of several Finnish specimens of E. clitellata ).

Host plants

Unknown.

Genetics

COI

Only one sequence available. The nearest neighbour, diverging by a minimum of 0.15%, is Euura clitellata (nuclear clusters 3 and 5). When secondary intraindividual COI variants of ZMUO.035580 are also included, maximum within species distance is 2.89% and the nearest neighbour, diverging by a minimum of 0.15%, is Euura clitellata ( E. clitellata s. str. and nuclear clusters 3–5).

Nuclear

Only one sequence available. The nearest neighbour, diverging by a minimum of 1.43%, is Euura moerens .

Distribution and material examined

Palaearctic. The studied specimen is from northernmost Finland.
