Pangacarus formosanus sp. nov. ( Fig. 5 )

Female: Body fusiform, 131 long, shield 35 long, 54 wide, shield lobe present; shield design with median line from base to basal 3/4, admedian lines complete, with 3 transverse lines at basal 1/4, half and basal 3/4, the basal 3/4 transverse line extending to lateral margin, submedian line absent; scapular tubercles set ahead of rear shield margin, scapular seta (sc) 5 long, directed to rear, Dt-Dt 23 apart. Legs: tibiae fused with tarsi; coxal area with granules; 1st coxal seta (1b) and tubercles absent, 2nd coxal seta (1a) 12 long, Ct2-Ct2 10 apart, 3rd coxal seta (2a) 17 long, Ct3-Ct3 21 apart, Ct2\Ct3 17, Ct2-Ct3 8; solenidion ending as knob; empodium simple, 5 rayed.

Opisthosoma: dorsum arched, dorsal annuli with 54 spiny microtuberculate rings, 1st 3 dorsal annuli 5 long; ventral annuli with 66 microtuberculate rings; lateral seta (c2) 8 long, Lt-Lt 42 apart, Lt\Vt1 44, Lt-Vt1 24; 1st ventral seta (d) 31 long, Vt1-Vt1 32 apart, Vt1\Vt2 37, Vt1-Vt2 29; 2nd ventral seta (e) 7 long, Vt2- Vt2 18 apart, Vt2\Vt3 39, Vt2-Vt3 35; 3rd ventral seta (f) 15 long, Vt3-Vt3 15 apart; accessory seta (h1) absent.

Epigynium: 19 wide, 13 long, with granules at base, with 2 transverse lines at each side, genital seta (3a) 5 long, Gt-Gt 15 apart.

Male: not seen.

Type data: Holotype Ψ, Taipei: Yangmingshan (685m; N25°10´E121°34´), 18-Aug.-1999, Huang & Wang; ex Callicarpa formosana Rolfe (Verbenaceae) . (deposited at NMNS). Paratypes, 3Ψ, 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 the second species in Pangacarus Manson, 1984 . This new species differs from P. grisalis by the shield design with median line, and with 3 transverse lines between the admedian lines.

Etymology: The specific designation is derived from the locality “ Taiwan ”, in reference to this species being the first species of Pangacarus found in Taiwan.
