Euura poppii

description: 127 Euura poppii (Konow, 1904) comb. nov.
Figs 127, 364
Pontania poppii Konow, 1904b: 230. Lectotype designated by Muche (1970a).
Pteronidea lindbergi Lindqvist, 1958: 105–106. Syn. nov. Pteronidea wolteri Lindqvist, 1958: 115–116. Syn. nov.
Pteronidea gracilicornis Lindqvist, 1962a: 121–122. Holotype lost? Type locality: Finland, Lapin Lääni, Kilpisjärvi. Syn. nov. 3.5–4.0 mm. Synonymy uncertain, but based on the original description (colouration, sawsheath, drawing of the tip of the lancet) it seems to fit best with darker forms of E. poppii.
Diagnosis
Usually extensively pale, but the body can be mostly black while the head remains extensively pale. The most similar are E. bipartita (specimens with dorsally black abdomen), E. fuscodorsata, E. fuscomaculata and E. lienterica, while darker specimens might be confused also with E. polaris, that has a rather similar lancet. Lancets of E. fuscodorsata (serrulae prominent and sharp) and E. lienterica (serrulae usually prominent and sutures somewhat S-shaped) can be distinguished from E. poppii (apical serrulae elongate and flat and sutures not distinctly curved). The lancet of E. fuscomaculata is very similar to E. poppii, but perhaps still with less protruding serrulae and the valvula 3 in dorsal view seems to be narrower in the middle and at its base compared to E. poppii. Lancet of E. bipartita (e.g., Fig. 99) can also be quite similar, but the specimens with dorsally black abdomen seem to have darker head and valvula 3 compared to E. poppii. Euura polaris usually has mostly black head or is somewhat brown behind the eyes (extensively pale in E. poppii), and its antennae are possibly shorter than in E. poppii. Usually, E. polaris also has broader sawsheath that in dorsal view is not distinctly narrowed at the tip as in E. poppii. Its extensively pale colouration and and penis valve shape (similar to e.g., E. leucopyga and E. parviserrata) and length (1.0– 1.1 mm, in most other Euura more than 1.2 mm) should distinguish E. poppii males reliably from the other Euura.
Female
4.0–5.0 mm. Head extensively pale around eyes; labrum, clypeus and supraclypeal area pale; flagellum black or pale ventrally; thorax black to extensively pale laterally and slightly pale dorsally; pronotum and tegula pale; pterostigma pale; metafemur pale or slightly black basally; metatibia pale; hind tarsus pale or brown (usually) to black; abdomen dorsally nearly completely black, ventrally nearly completely black to completely pale; valvula 3 basally pale; mesepisternum smooth; claws bifid; lancet with 15–17 serrulae.
Male (based on two specimens)
3.5–4.0 mm. Head extensively pale around eyes; labrum, clypeus and supraclypeal area pale; flagellum pale ventrally; thorax black dorsally, extensively pale laterally; pronotum and tegula pale; pterostigma pale; metafemur pale; metatibia pale; hind tarsus pale or brown; abdomen dorsally nearly completely black, ventrally pale; sternum 9 pale; mesepisternum smooth; claws bifid or with small subapical tooth.
Type material examined
Lectotype Pontania poppii
RUSSIA • ♀; Kanin Peninsula; 68.0° N, 45.0° E; B. Poppius leg.; SDEI, GBIF-GISHym3865.
Notes
Lancet more similar to parvulus syntype NHRS-HEVA 000006478 than NHRS-HEVA 000006479. Lancet fits best with wolteri holotype. Abdomen ventrally pale. Head and thorax missing. Possible paralectotypes in MZH have long antennae.
Holotype Pteronidea lindbergi
RUSSIA – Murmansk oblast • ♀; Petsamo [Pechenga]; 69.54° N, 31.19° E; 20 Jul. 1929; H. Lindberg leg.; MZH, http://id.luomus.fi/GL.3571.
Notes
16–17 serrulae. Best morphological match: DEI-GISHym21379 (15–16 serrulae).
Holotype Pteronidea wolteri
RUSSIA – Murmansk oblast • ♀; Petsamo [Pechenga], Yläluostari [Luostari]; 69.43° N, 31.04° E; 10 Jul. 1930; W. Hellén leg.; MZH, http://id.luomus.fi/GL.3598.
Notes
Lancet fits rather well with poppii (lectotype and DEI-GISHym21379). Externally fits best with the winteri holotype.
Host plants
Unknown.
Genetics
COI
Based on 6 specimens, maximum within-species distance is 3.95% and the nearest neighbour, diverging by a minimum of 1.37%, is Euura polaris.
Nuclear
Based on 5 specimens, maximum within-species distance is 0.72% (0.51% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.76%, is Euura leptostigma.
Distribution and material examined
Palaearctic. Specimens studied are from Finland, Norway, Russia, and Sweden.
