Figs 28 , 29 Notes. Rhadinoceraea sibiricola Zhelochovtsev, 1939: 159-160. ♀. Holotype. Type locality: Russia, Krasnoyarsk Krai, Vostotschnoe (35 km SE of Minussinsk). In the original description, Zhelochovtsev (1939) compared R. sibiricola with " Rh. japonica Malaise" [ Phymatoceropsis japonica (Malaise, 1931) ( Malaise 1931a )], and stated that they are "closely allied". Comparison of female P. sibiricola specimens from Finland (Fig. 28 ) with a Japanese female of P. japonica in the SDEI collection confirmed their similarity. As mentioned by Zhelochovtsev, P. japonica has much longer antennae, but the differences described in the structure of the frontal area and mesopleura seemed less clear. The host plant of P. sibiricola , as discovered by Vikberg in Finland (see below), is Sambucus racemosa ( Adoxaceae ), since verified several times by Mutanen. The host plant of P. japonica is Sambucus sieboldiana Blume ( Okutani 1956 ), which is sometimes treated as a synonym or subspecies of S. racemosa L. Figure 28.

Oviposition trial by Vikberg (3/2011 VV): three females captured in Hangastenmaeki in 2011 were used in this experiment. Adoxa , Sambucus racemosa , Lonicera xylosteum and Galium sp. were offered to them. They laid eggs only on Sambucus racemosa leaves. The egg is laid through the upperside of the leaf into the tissue of the underside, usually one to two eggs per leaflet, but in one small leaflet eight eggs were counted. Oviposition occurred on 21.05.-24.05. The first larvae were observed on the morning of 28.05. Later, 28 larvae were counted. Five feeding instars were observed and after finishing feeding there was an "extra moult". Prepupae were seen on 07.06-08.06. 1st and 2nd instar larvae are gray, with a brown head. 5th instar larvae are 13-14 mm long; head width ca. 1.6 mm (Fig. 29 ). Head brownish, behind the eye a black fleck which is curved backwards and upwards. Body dorsally dark gray with greenish hue; ventrally whitish gray. Black suprastigmal flecks on thoracic segment 3 and abdominal segments 1-9. Figure 29. Phymatoceropsis sibiricola (Zhelochovtsev, 1939). A-C. Nearly fully-fed larvae on Sambucus racemosa .
