Etymology
Etymology. The species name is derived from the Latin word ‘ pyriformis ’, meaning pear-like, and refers to the shape of the bulb in ventral view; adjective.
Diagnosis
Diagnosis. The new species is similar to O. liupan (Hu & Zhang 2011: 61, figs 1–7) in having a similar bulb and a broad MP, but can be distinguished from O. liupan by: 1) TA absent (present in O. liupan); 2) CD curved and thick (straight and thinner in O. liupan); 3) BU large and kidney-shaped (smaller and round in O. liupan). The new species is similar to O. papilion sp. nov. (Figs 5–6), but can be distinguished by: 1) hook-shaped E (sickle-shaped in O. papilion sp. nov.); 2) RTA with a beak-like tip (tip tapering in O. papilion sp. nov.); 3) CD straight (curved in O. papilion sp. nov.); 4) MP present (absent in O. papilion sp. nov.).
