PLATE 1. Taijutarus triangulus gen. et sp. nov. A. Dorsal view; B. Geitalia and coxal region, female; C. Ventral view; male; D. Empodium.

Opisthosoma: arched, dorsum with 42 annuli, microtuberculate; ventrally with 50 microtuberculate annuli, first 3 dorsal annuli 7 long; lateral setae (c2) absent; 1st ventral setae (d) 28 long, Vt1\Vt2 40, Vt1­Vt2 28; 2nd ventral setae (e) 8 long, Vt2­Vt2 21 apart, Vt2\Vt3 47, Vt2­Vt3 44; 3rd ventral setae (f) 18 long, Vt3­Vt3 17 apart; accessory setae (h1) absent, caudal seta (h2) 31 long.

Coverflap: 21 wide, 11 long, with about 9 longitudinal ridges, genital setae (3a) 10, Gt­Gt 18 apart.

Male: not seen.

Type data: Holotype, female, NANTOU: Renai Township; 2­Nov.­1990, K. W. Huang; ex Pericampylus formosanus Diels (Menispermaceae) . (deposited at NMNS). Paratypes, 2 females, with same data as holotype.

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

Etymology: This new name means “triangular” in reference to the shield design with a triangular shape cell at each sides.

PLATE 2. Jutarus pasanus sp. nov. A. Prodorsal shield; B. ventral view, female.

Male: not seen.

Type data: Holotype, female, NANTOU: Renai Township; 6­Oct.­1994, C. F. Wang; ex Pasania konishii (Hay.) Schottky (Fagaceae) . (deposited at NMNS). Paratypes, 2 females, with same data as holotype.

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

Note: This new species is close to Jutarus benjaminae Boczek et Chandrapatya, 1989 differing in the submedian lines complete and by the 6 rayed empodium.
