Siobla pseudoplesia Niu et al., 2012: 410 . f #, type locality: Mt. Shennongjia, Hubei ( China).

Distribution. China (Ningxia, Shaanxi, Shanxi, Henan, Hubei, Sichuan).

The species is similar to S. acutitheca Niu & Wei, 2010 but differs from it in the ovipositor sheath distinctly shorter than middle tibia, the apical sheath very narrow in lateral view and acute at apex, the middle breadth of apical sheath about half breadth of the apex of hind tibia; the serrulae weakly sclerotized and almost flat, the 10th serrula with 10–12 minute teeth; the postocellar area as broad as long; the interspaces between punctures on mesonotum microsculptured, almost mat; the abdominal tergite 1 weakly microsculptured, tergites 2–9 hardly microsculptured; and the first pulvillus small, distinctly shorter than half apical breadth of metabasitarsus.
