One of the specimens (Fig. 5A-D), body length: 16.2 mm, antennae 1.2 times as long as body, length (mm) of each antennomere: scape = 3.25, pedicel= 0.5, III = 3.6, IV= 2.5, V = 2.0, VI = 1.75, VII = 1.5, VIII = 1.4, IX = 1.25, X = 1.0, X I = 0.75; elytra 1.72 times as long as wide.
Comments.
According to Mr Mao Ye (pers. comm.) an unknown rotten vine was broken apart by hand, exposing numerous ants, a live male adult (Fig. 4E-F) and a female pupa (Fig. 5E) of E. ziranzhiyi. The live adult was placed on surface litter and the pupa was placed on a dried leaf for photographs. The pupa eclosed after several days.
The two inward oblique and sub-oval pubescent pink spots on the vertex are not well-defined on some males (Figs 3A, 4A), the two sub-rounded pink spots on the sides of the center of the frons are not well-defined on some males (Fig. 3 in Yamasako and Lin 2016, fig. 4D) and a female deposited in YZU.
Distribution.
