Uropoda setata sp. nov.

(Figs 42–48)

Material examined. Holotype. Female (HNHM), Vietnam, Tam Dao, submontane foggy forest, litter sample, altitude ca 1200 m, 16 October 1988, J. Starý coll. Paratype. One female (ISB). Locality and date same as holotype. Description. Female. Length of idiosoma 850–960 µm, width 740–750 µm (n=2). Shape oval, highly domed.

Dorsal idiosoma (Fig. 42). Marginal and dorsal shields not fused. Central region of dorsal shield elevated from the other parts of dorsum, but one deep, transverse furrow located at level of coxae IV (Fig. 44). Dorsal setae smooth and needle-like, margins of dorsal shield with ca 45–50 µm long setae, central region with shorter (ca 50 µm) and longer (140–210 µm) setae, the long setae located on anterior margin of deep transverse furrow. Submarginal shield reduced and covered by small oval pits. Setae on submarginal shields long, smooth ca 110–120 µm long, one pair of setae situated near posterior margins of submarginal shields, these setae similar in shape and length to submarginal setae. Margins of idiosoma with 30–35 µm long, needle-like setae.

Ventral idiosoma (Fig. 43). Ornamentation on sternal shield absent. Sternal setae short (ca 5–7 µm), smooth and needle-like. St1 situated near anterior margin of genital shield, St2 at level of posterior margin of coxae II, St3 at mid-level of coxae III, St4 at mid-level of coxae IV, St5 near posterior margin of genital shield. Five pairs of extremly long (120–145µm), needle-like setae situated in central and lateral area of ventral shield; two pairs of short (10–14 µm), needle-like setae placed lateral to anal opening. Caudal margins of ventral idiosoma with numerous long, needle-like setae, 30–35 µm. Ventral shield without sculptural pattern, but tile-like ornamentation situated laterally to pedofossae of coxae IV. Stigmata situated between coxae II and III. Peritremes S-shaped. Genital shield linguliform, without sculptural pattern or apical process. Base of tritosternum wide, tritosternal laciniae with four short, lateral branches and a long, smooth central point (Fig. 45).

Gnathosoma (Fig. 46). Corniculi horn-like, internal malae longer than corniculi, their margins pilose. Hypostomal setae h1 smooth, long (83–85 µm), situated near anterior margin of gnathosoma, h2, h3 and h4 marginally serrate, ca 19–20 µm long. Base of epistome with serrate margins, apical part marginally pilose. Movable digit of chelicera shorter than fixed digit, internal sclerotised node absent (Fig. 48).

Etymology. The name of the new species refers to the long dorsal and ventral setae.

Remarks. The new species belongs to Uropoda gibba group (Hirschmann, 1976b), on the basis of the highly domed dorsal shield with a transverse furrow, and long setae in the central region of the dorsum. Eight species are known from this group, occurring in Japan, New Guinea and Vietnam (WiŠniewski & Hirschmann, 1993). The new species can be easily separated from the other species of this group on the basis of the short setae lateral to the anal opening.
