Pachynematus sagulatus Konow, 1903: 382 (key). Lectotype ♀(GBIF-GISHym3903; designated by Oehlke and Wudowenz 1984, as “Holotypus”) in SDEI, examined. Type locality: Hungaria bor. Tatra [Tatra Mountains], Poland or Slovakia.

Lygaeonematus leucopodius ab. flavipes Lindqvist, 1941: 70. Not available. Infrasubspecific name.

Nematus (Pikonema) piceae Zhelochovtsev in Zhelochovtsev and Zinovjev, 1988: 170, syn. n. Holotype ♀ in ZMUM, not examined. Type locality: Srednyaya Usva [ Средняя Усьва], Perm Krai, Russia.

Pristiphora (Pristiphora) hoverlaensis Haris, 2001: 82, syn. n. Holotype ♂ (DEI-GISHym80339; http://dx.doi.org/10.6084/m9.figshare.5091895) in HNHM, examined. Type locality: Bohdan ( Богдан), Zakarpattia Oblast, Ukraine.

Similar species.

The most similar species is P. nigriceps , females of which have an extensively pale thorax and abdomen. In P. leucopodia , thorax and abdomen are usually black, palest specimens have a nearly completely pale abdomen and slightly pale thorax. Males are best recognised by examining penis valves. Although we did not study the holotype of piceae Zhelochovtsev, differences mentioned by Zhelochovtsev and Zinovjev (1988) in lancet, coloration and length of antennae seem to be minute. Examination of female specimens that vary in coloration and length of valvula 3 did not allow separation of two forms, as the variation seems to be continuous. Neither were reliable differences detected in the lancet. The penis valve of one male identified by Alexey Zinovjev as piceae is indistinguishable from leucopodia .

Genetic data.

Based on COI barcode sequences, P. leucopodia belongs to its own BIN cluster (BOLD:AAH7553) (Fig. 3). Maximum distance within the BIN is 1.83%. The nearest neighbour to BOLD:AAH7553, diverging by minimum of 5.06%, is BOLD:AAQ3707 ( P. laricis ). Based on nuclear data, maximum within species divergence is 0.9% (based on three specimens and NaK) and the nearest neighbour is 2.4% different ( P. nigriceps , both genes combined).

Host plants.

Picea abies (L.) Karsten ( Pschorn-Walcher and Altenhofer 2000), P. pungens Engelm. ( Kula et al. 2016).
