Diagnosis: This species is similar to M. (P.) yunanensis (Zhang) but it differs by having pointed setae on the dorsal abdomen, URS 0.80-1.00 × HT II (1.50-1.70 in M. yunanensis ), and PT 0.90-1.10 × BASE (0.60-0.70 in M. yunanensis ).

Redescription (Alate viviparous female): Color in life: Head and antenna pale yellow, distal joint of ANT III-VIb dark. Thorax and abdomen pale yellow. Legs pale, distal 1/3 of fore tibiae and tarsi fuscous. Wing vein Cu1b of forewing dark bordered. SIPH and cauda.

Morphology: Body oval, BL 1.24-1.61 mm. Head smooth with a flat median protrusion on frons, epicranial suture weakly indicated, head vertex with 0.01 mm pointed setae, head dorsum without tubercles. ANT 6-segmented, ANT 1.02- 1.29 × BL, ANT III with 7-12 transversely elliptical formed secondary rhinaria in a row on the whole segment, ANT III-VI imbricated with inconspicuous hair-like setae, ANT IV without secondary rhinaria, ANT V shorter than ANT IV, PT 0.92-1.10 × BASE. Rostrum not reaching to middle coxae, URS 0.08- 0.09 mm long with 4-5 accessory setae, 0.80-1.00 × HT II. Thorax smooth, without tubercles. Fore coxae weakly enlarged, longest setae on TIBIAE III 1.00-1.50 × middle width of TIBIAE III, HT I with 7-8 chaetotaxy, HT II 0.08-0.11 mm long. Dorsal spinal setae sometimes on small elevations, conspicuous tubercles not developed, ABD VIII with a pair of setae, ABD margin I-IV with 2 setae on short cone-shaped tubercles, 4th marginal tubercle 0.02-0.04 mm. SIPH cylindrical, truncated, 0.05- 0.07 mm long. Cauda knobbed, 0.08-0.10 mm long, bearing 10-14 setae. Anal plate bilobed, each lobe with 6-11 setae.

Distribution: The species is rather common in the Korean peninsula (both North and South Korea), China ( Zhang et al. 1986), and Japan ( Higuchi 1972).

Host plant: The species feeds on several species of Corylus ( Betulaceae ) in almost whole distributional range, but in Russian Far East it was collected from Quercus dentata ( Holman 2009) .

Remarks: In Paik’s collection, some specimens were collected on Alnus japonica and Physocarpus insularis . However, these do not seem to be a true host plants because M. (P.) corylicola is typically recorded as Corylus .
