Material.

1 ♀ (RMNH), "[Japan:] Mt. Hiei, 15.v.1996, H. Takada", "Host: Sappaphis piri ", " Paralipsis eikoae (Yasumatsu), det. H. Takada, 2015".

Diagnosis.

This species shares with Paralipsis enervis having the secondfourth 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 dull and posteriorly finely sculptured scutellum (Fig. 7), the rather short third–fifth antennal segments (Fig. 4), the largely dull and distinctly finely sculptured mesoscutum (Fig. 7), the more robust middle and hind femora and tibiae, the micro-sculptured hind tibia (Figs 1-2), the vein 2-1A of fore wing absent (Fig. 6) and the slenderer first tergite (Fig. 3).

Biology.

Parasitoid of root aphids attended by the ants Lasius sakagamii Yamauchi & Hayashida, 1970 or Lasius japonicus Santschi, 1941 ( Yu et al. 2012, Akino and Yamaoka 1998). Holotype male was collected from a nest of Lasius japonicus (published as Lasius niger ; see Seifert 1992) in an old Cryptomeria japonica tree and the species was reared as parasitoid of the aphid Sappaphis piri Matsumura, 1918, on roots and subterranean stems of Artemisia princeps Pamp. ( Takada 1976).

Distribution.

Reported from Japan and Far East Russia ( Yu et al. 2012).
