Dolerus subfasciatus rhodogaster: Zhelochovtsev & Zinovjev 1992: 211.
Distribution. Eastern Palaearctic. China: Manchuria (see data of the lectotype above; Zhelochovtsev 1935). All records from the literature and the paralectotypes need verification as there might be a resembling species (see taxonomic notes below). Russia (Zhelochovtsev 1935): Amur District, Blagoveshchensk (2Ƥ, 9.VI 1931 and 4.VII 1927, V. Verestshagin [leg.]); Budunda (1Ƥ, 29.V 1930, A. Shein [leg.]); Sichote-Alin: Shkotovo (4Ƥ13, 3 -6.VI 1927, A. Zhelochovtsev [leg.]); Shkotovo, Maiche (1Ƥ, 17.VI 1929. Shablkovski [leg.]); East Siberia (Verzhutskii 1966, under the name D. subfasciatus v[ar]. rhodogaster): River Malaja Bystraja [Slydyanskij rajon, Irkutskaja oblast] (1Ƥ, 27.VI 1955); Zun-Murino [Tunkinskij ajmak, Buryatia] (1Ƥ, 2.VI 1961); Irkutsk (13, no date, V. Jakowlew [leg.]); Tibel´ti [Slydyanskij rajon, Irkutskaja oblast] (2Ƥ, 2.VII and 4.VII 1963); Baikal Region, Tunkinskaja dolina [plain].
Specimens studied. Lectotype Ƥ, 13 (both in ZIN).
Host plant. Unknown.
Taxonomic notes. The lancet of the lectotype female (Fig. 6) fits the fragment illustrated by Zhelochovtsev (1935: fig. 3). The only syntype male mentioned in the original description was not available for study, but we studied one male from the collection of Semenov-Tian-Shansky collected in Irkutsk (Russia) by Jakowlew, which most likely belongs to this species (penis valve in Fig. 15). The colour of the abdomen in this male is not completely black as it was noted by Zhelochovtsev (1935) for the syntype male of D. picinus rhodogaster (ZMUM, not examined), but it resembles the lectotype female which has some middle abdominal segments partly red. Also the structural characters mentioned in the description, including the long ventro-apical thorn-like process of the penis valve (not illustrated in Zhelochovtsev 1935) and the structure of the abdominal terga fit this male from Irkutsk (labelled: " Dolerus picinus Marl. subsp. nov? 3 A.Zhelochovtsev det. 1933"; its genitalia were not studied by Zhelochovtsev). Paralectotypes: 8Ƥ 13 in ZMUM (3Ƥ of them were mentioned as paratypes in Zhelochovtsev & Zinovjev 1992 but had in fact syntype status). Large females with extensively red abdominal segments 2–6 (from South Korea, in USNM) and resembling D. rhodogaster (identified as D. subfasciatus by A. Haris) neither belong to this species nor to D. neoaprilis; their identity needs futher study and additional material.
