Phymatoceropsis sibiricola

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

Raekunnas (ZMUO). Biology. Oviposition trial by Vikberg (3/2011 VV): three females captured in Hangastenmäki in 2011 were used in this experiment. <i>Adoxa</i>, <i>Sambucus racemosa</i>, <i>Lonicera xylosteum</i> and <i>Galium</i> sp. were offered to them. They laid eggs only on <i>Sambucus racemosa</i> 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.
