Pristiphora pseudogeniculata Lindqvist, 1969: 246. Holotype ♀ (http://id.luomus.fi/GL.5215) in MZH, examined. Type locality: Helsinki, Finland.

Similar species.

The most similar species is P. geniculata . Both females and males of P. geniculata have longer antenna (2.4-2.5 times as long as head width compared to 1.9-2.1 in P. pseudogeniculata ) and a darker metatarsomere 1 (largely black compared to completely or nearly completely pale in P. pseudogeniculata ). The female of P. geniculata also has a different lancet (see the Key).

No data.

Host plants.

Prunus padus L. (ex ovo rearing experiments by VV).

Rearing notes.

Ovipositing experiment no. 3/1979: Finland, South Häme, Hämeenlinna, Katinen. One female was captured on 4.VI.1979 and leaves of Malus sp., Sorbus aucuparia and Prunus padus were offered her. On 4-5.VI.1979 she laid several eggs only in teeth of leaves of Prunus padus . Four larval instars were observed. Larvae feed gregariously on the leaf margin, like larvae of P. geniculata on Sorbus aucuparia . Prepupae were seen on 19.VI.1979. No extra moult after feeding.

Distribution and material examined.
