( Figs 12–22 View FIGURES 12 – 19 View FIGURES 20 – 22 )
Material examined. Holotype. Female, Thailand, Trat prov., Ko Chang, West side, near Kai Bae beach, 2–6 November 2006, A. Schultz coll. Paratypes. Two males, same data as holotype.
Description. Female. Length of idiosoma 850 µm, width 640 µm (n=1). Shape oval, dorsally domed and strongly sclerotized.
Dorsal aspect of idiosoma ( Fig. 12 View FIGURES 12 – 19 ). Dorsal and marginal shields fused anteriorly, dorsal setae on central area short (ca. 40–45 µm) and smooth ( Fig. 13 View FIGURES 12 – 19 ), other dorsal setae marginally pilose ( Fig. 14 View FIGURES 12 – 19 ), ca. 70 µm long near caudal margins and ca. 40 µm long near lateral margins. Dorsal shield covered by small, oval pits laterally and with web-like sculptural pattern in central area. Marginal shield with marginally pilose setae ca. 50 µm long ( Fig. 15 View FIGURES 12 – 19 ). Marginal shield covered by irregular oval pits on its surface. Postdorsal shield present, with a large, weakly sclerotised, membranous caudal appendix.
Ventral aspect of idiosoma ( Fig. 16 View FIGURES 12 – 19 ). Surface of sternal shield smooth, only two pairs of sternal setae clearly visible on the single specimen, St1 (ca. 18 µm) smooth, needle-like, situated at level of anterior margins of coxae II, St5 (ca. 50 µm) needle-like and smooth, placed near basal edges of genital shield. Ventral shield covered by web-like sculptural pattern extending posterior to a transverse row of ventral setae; caudally from this line surface smooth with several longitudinal furrows. Ventral setae ( Fig. 17 View FIGURES 12 – 19 ) ca. 90 µm long, positions as shown in Fig. 16 View FIGURES 12 – 19 . Adanal setae ( Fig. 18 View FIGURES 12 – 19 ) short (ca. 30 µm), smooth, postanal setae absent. Pedofossae deep, their surface smooth, without separate furrows for tarsi IV. Genital shield linguliform, anteriorly rounded, its surface with web-like sculptural pattern. Stigmata situated between coxae II and III, peritremes M-shaped. Tritosternum with narrow base, laciniae subdivided into four marginally pilose branches ( Fig. 19 View FIGURES 12 – 19 ).
Gnathosoma ( Fig. 19 View FIGURES 12 – 19 ). Hypostomal setae h1 (ca. 60–62 µm) subdivided into two branches, one smooth and other one marginally pilose, h2 short (ca. 18–20 µm), smooth, h3 and h4 marginally serrate, short (ca. 16–18 µm). Corniculi short and horn-like, with five lateral spines, internal malae longer than corniculi and marginally pilose. Epistome apically pilose. Chelicerae not clearly visible.
Legs. Leg I without ambulacral claws, each leg with smooth and pilose setae.
Male. Length of idiosoma 820–850 µm, width 530–540 µm (n=2). Shape and dorsal aspect of idiosoma as in female.
Ventral aspect of idiosoma ( Fig. 20 View FIGURES 20 – 22 ). Surface of sternal shield covered by web-like sculptural pattern, four pairs of sternal setae (ca. 25–35 µm long) present anterior to genital opening, one pair (ca. 35 µm) near lateral margin, and one pair (ca. 50 µm) near posterior margin of genital plate. Setae St3 marginally pilose, other sternal setae smooth. Position and shape of ventral setae and ornamentation of ventral shield as in female. Genital shield circular, without sculptural pattern, situated between coxae IV. Tritosternum with narrow base, laciniae subdivided into four marginally pilose branches ( Fig. 21 View FIGURES 20 – 22 ).
Gnathosoma ( Fig. 22 View FIGURES 20 – 22 ). Hypostomal setae h1 (ca. 43–50 µm) subdivided into two branches, one smooth, one marginally pilose, h2 short (ca. 10 µm) and smooth, h3 and h4 marginally serrate, short (ca. 7–9 µm). Corniculi short and horn-like, with five lateral spines, internal malae longer than corniculi, marginally pilose. Epistome apically pilose. Apical part of chelicerae long, narrow, without visible teeth.
Etymology. The name of the new species refers to the country where it was collected.
Remarks. The new species is unique in the genus Hutufeideria in having the genital shield of the female, the sternal shield of the male and the ventral shield of both sexes covered by a web-like sculptural pattern.
