Milema sai Zhao & Li , sp. nov. ( Figs 46–47 View Figure 46 View Figure 47 )

Diagnosis. This species resembles M. nuichua Zhao & Li , sp. nov., but can be distinguished by the distal tibia thinner than the basal cymbium of the male palp ( vs. wider), the ellipsoidal bulb ( vs. irregular), the tip of the embolus membranous ( vs. sclerotized); spermatheca globular with membranous and sclerotized tubes inside ( vs. no tubes).
