Figs 1–2, 7
Differential diagnosis
The male of this new species resembles that of M. lingbaoshanensis sp. nov., but can be distinguished from the latter by: 1) vexillum of male palp ox-horned in retrolateral view (Figs 1C, 2B) versus handlelike in M. lingbaoshanensis sp. nov. (Figs 3C, 4B); 2) distal portion of paracymbium claviform in retrolateral view (Figs 1C, 2B) versus lamelliform in M. lingbaoshanensis sp. nov. (Figs 3C, 4B); 3) tibia about 2 times longer than cymbium (Figs 1C, 2B) versus as long as cymbium in M. lingbaoshanensis sp. nov. (Figs 3C, 4B).
Etymology
The specific name comes from the Latin ‘ bucerus ’ (‘ox-horned’), refers to the shape of the vexillum of the cymbium.
