Gammaphytoptus commune sp. nov. ( Fig. 9 ; Pl. 2 C, D)

Female: Body fusiform, 183 long; shield 36 long, 60 wide, anterior lobe present; shield design without median line, admedian lines complete, converging to apex, submedian line absent; scapular tubercles set on shield rear margin, setae (sc) 30 long, directed to rear, Dt-Dt 32 apart; leg segments normal, fore tibial setae at half, 4 long; coxal area smooth, 1st coxal setae (1b) 6 long, Ct1-Ct1 14 apart, 2nd coxal setae (1a) 10 long, Ct2-Ct2 16 apart, 3rd coxal setae (2a) 20 long, Ct3-Ct3 28 apart, Ct1\Ct2 15, Ct1-Ct2 7, Ct2\Ct3 22, Ct2-Ct3 8; genitalia append to coxae; claw ending as knob; empodium simple, 7-rayed.

Opisthosoma: arched, dorsal annuli with about 58 microtuberculate rings, first 3 rings 8 long; ventral annuli with 78 microtuberculate rings; lateral setae (c2) 18 long, Lt-Lt 54 apart, Lt\Vt1 55, Lt-Vt1 30; 1st ventral setae (d) 42 long, Vt1-Vt1 38 apart, Vt1\Vt2 46, Vt1-Vt2 35; 2nd ventral setae (e) 19 long, Vt2-Vt2 22 apart, Vt2\Vt3 66, Vt2-Vt3 64; 3rd ventral setae (f) 15 long, Vt3-Vt3 15 apart; accessory setae (h1) present.

Epigynium: 25 wide, 15 long, with two rows of lines, each row with about 14 longitudinal lines, genital setae (3a) 10 long, Gt-Gt 13 apart.

Male: not seen.

Type data: Holotype Ψ, Taipei: Yangmingshan (600m; N25°09´E121°34´), 24-Aug.-1999, Huang & Wang; ex Lindera communis Hemsl. (Lauraceae) . (deposited at NMNS). Paratypes, 4Ψ, data same as for holotype.

Relation to host: A vagrant on the lower leaf surface. No apparent damage was observed.

Remarks: This new species is not particularly close to any other known species by the shield design without median line.

Etymology: The specific designation is derived from the specific name of the type host plant.
