PHOTO 1. Blister galls on both leaf surfaces of Lycium chinense caused by Aceria kuko (Kishida, 1927) .

Female: (n=11) Body worm-like, 160 long, prodorsal shield 30 long, 40 wide, with a protuberance between scapular tubercles, granules at basal center, scapular tubercles set at prodorsal shield rear margin, setae (sc) 22 long, directed backward, sct-sct 23 apart; leg segments normal, foretibial seta (1') set at basal one-third, 5 long; 1st coxal setae (1b) 9 long, 1bt-1bt 8 apart, 2nd coxal setae (1a) 15 long, 1at-1at 6 apart, 3rd coxal setae (2a) 21 long, 2at-2at 18 apart; solenidion ending as a knob; empodium simple, 5 rayed.

Opisthosoma: with about 73 microtuberculate rings; first 3 rings 4 long; lateral setae (c2) 33 long, c2t-c 2t 39 apart, c 2t \dt 41, c2t-dt 23; 1st ventral setae (d) 52 long, dt-dt 33 apart, dt\et 56, dt-et 26; 2nd ventral setae (e) 37 long, et-et 19 apart, et\ft 45, et-ft 40; 3rd ventral setae (f) 19 long, ft-ft 22 apart; setae h1 present.

Coverflap: 16 wide, 9 long, with several vague longitudinal ridges, genital setae 15 long, 3at -3at 13 apart.

Male: not seen.

Specimens examined: 11 females, Kimsha, Kimen; 6-Mar.-1997, K. W. Huang; 4 females, 28-Jul.-2004, Fongsan, Kaohsiung; C. S. Ho; ex. Lycium chinense Mill. (Solanaceae) .

Relation to host: Blister gall protruding from the lower surface of leaf; ostiole opening to lower surface.

Note: The author examined slides of A. tjyingi (Manson, 1973), the species found infesting Lycium chinense in Taiwan, and discovered that the admedian lines showed variations in length. The admedian lines varied from base to basal 1/4, or to basal 1/3, or to one half or complete.

Distribution: Japan, mainland China, Taiwan.
