Diagnostic description.

Female (n = 8). Body length: 2.1-2.4 mm; fore wing length: 2.1-2.4 mm; F2 L/W: 1.1-1.3 ×; F14 L/W: 1.1-1.4 ×; F15 L/W: 1.2-1.4 ×; F2 L/F14 L: 1.1-1.3 ×; OOL/ OD: 1.9-2.3 ×; POL/OD: 1.4-1.5 ×. Fore wing with vein 2CUa entirely nebulous; vein R1 shorter than pterostigma length and a little longer than distance delimited between end of vein R1 and end of vein 3RSb. Fore wing with areolet triangular and relatively small, its maximum height 0.3-0.4 × vein r length, its maximum width 0.4-0.6 × vein r length. Propodeum mostly smooth and shiny, with some rugosity longitudinally and along median transverse carina; median longitudinal carina complete, at least on anterior 0.5; transverse carina more or less developed. Metafemur L/W: 2.6-2.8 ×. Anterior 0.5 of T1 irregularly rugose, at least laterally, rest of T1 and T2 mostly smooth; T1 median length 1.8-2.0 × its width at posterior margin; T2 width at posterior margin 2.0-2.2 × its median length. Metatibia L: 0.74-0.84 mm. Metatibia L/ovipositor sheath L: 2.0-2.6 ×. Ovipositor sheath L: 0.31-0.38 mm. Maximum length of setae on ovipositor sheath much longer than maximum width of ovipositor sheath.

Body dark brown to black. Mouth parts, humeral complex, wing veins (except sometimes for C+SC+R, pterostigma, R1), trochantelli, posterior 0.2 of pro- and mesofemora, pro- and mesotibiae and tarsi, anterior 0.2 of metatibia and sternites brown to yellowish-brown. Palpi yellow.

Male (n = 1). Similar to female, except for flagellomeres with two ranks of placodes; F2 L/W: 1.9 ×; F14 L/W: 2.3 ×; F15 L/W: 2.3 ×.

Hosts.

Unknown.

Distribution.

Eastern Palaearctic: Japan (Hokkaido).

Etymology.

Named " Paroplitis horticola " because type specimens were collected from a Malaise trap set in a garden.
