Female. Body length 12.0 mm; fore wing length 9.0 mm.
Head
densely punctate, with golden yellow setae, transverse, much wider than long (46: 25), slightly broader than
mesosoma

); ratios POL/LOL/ OOL=14:7:20; ocelli large, their maximum diameter more than LOL (
Fig. 11
); eyes oval, inner margins almost parallel, eye much narrower than high (43: 80); face below antennal sockets with tubercle (
Fig. 10

Host.
Unknown. There are three species of
Megaxyela
Ashmead
, which are distributed in the
South Korea
:
M. parki
Shinohara, 1992
,
M. gigantea
Mocsáry, 1909
and undescribed species (Blank
et al.
in litt.), which may be the potential hosts of
Proctorenyxa koreana
sp. nov.
Distribution.
South Korea
(Gyeongsangbuk-do, Gangwon-do).
Etymology.
The species is named after the
type
locality.
