Material examined. Holotype of Macropelopia grandivolsella : M ( BNKU), labelled “BDN No. 11883”, CHINA: Hubei Prov., Hefeng County, Fenshuiling , 17.vii.1999, B.C. Ji . Paratype of Macropelopia grandivolsella : 1M ( BNKU), labelled “BDN No. 13779”, CHINA: Hubei Prov., Xianfen City, Gong River , 25.vii.1999 , B.C. Ji. Nontype: 1 Pe, CHINA: Beijing City, Beijing Botanical Garden, Cherry Valley , 40°00'39.75"N 116°12'06.64"E, alt. 141 m, 22.ix.2011 .

Remarks. In the original description of Macropelopia grandivolsella Wang, Cheng et Wang, 2011 , the authors (op. cit.: 4125, 4126) wrote, “Wing with brown markings on basal of Cu1 and cell r4+5. Tergite IX developed, without setae. Inferior volsella conspicuous, large and strong.” However, reexaminations of the holotype and paratype males revealed that the wing has more extensive markings on the cross-veins and membrane ( Figure 2A ), the abdominal tergite IX bears 30–32 posterior setae, and that in both the specimens, the hypopygium ( Figure 2B ) was crushed by the cover-glass and the base of the gonocoxite was produced inwards. The characters of this species, including the abdomen with strongly pigmented central and lateral markings on the tergites I–IV, and the yellow femora with a broadly brown caudal margin, are consistent with those of M. (Macropelopia) paranebulosa Fittkau redescribed by Niitsuma et al. (2004).

The pupal exuviae collected from Beijing City in 2011 by the first author has the characters of M. (Macropelopia) paranebulosa as in Table 2. It strongly supports the wide distribution of this species in Palaearctic (Beijing) and Oriental China (Hubei) as well as Palaearctic Japan ( Niitsuma et al. 2004) and Russia ( Makarchenko & Petrova 1988).
