Diagnosis.

This species shares with Paralipsis eikoae having the second-fourth segments of fore tarsus about as long as wide in dorsal view, the fore tarsus with medium-sized bristles apically (Figs 1, 8) and the hind tibia medially and femur subbasally parallel-sided (Figs 1, 2, 8). Differs by the shiny and smooth scutellum (Fig. 9), the brownish scutellum, the longer third–fifth antennal segments (Fig. 12), the shiny and mainly smooth mesoscutum (Fig. 10), the slenderer middle and hind femora and tibiae, the hardly or not sculptured hind tibia (Fig. 8), the largely or entirely sclerotized vein 2-1A of fore wing (Figs 13-14) and the less slender first tergite (Figs 9, 11).
