Hutufeideria alata sp. nov.

( Figs 29–35 View FIGURES 29 – 32 View FIGURES 33 – 35 )

Material examined. Holotype. Female, Thailand, NE from Bangkok, Khao Yai National Park, 750–850 m, 26.IX.– 3.XII. 1985; leg. D. Burckhardt & I. Löbl. Paratypes. One male; same data for holotype.

Description. Female. Length of idiosoma 1090 µm, width 700 µm (n= 1). Shape pentagonal, dorsally domed and strongly sclerotized.

Dorsal aspect of idiosoma ( Fig. 29 View FIGURES 29 – 32 ). Dorsal and marginal shields fused anteriorly, dorsal setae in central area long (ca. 110–140 µm), smooth and needle-like, the first pair of dorsal setae (ca. 50–55 µm) marginally pilose. Setae near caudal margin pilose and setiform (ca. 110–140 µm), except posteriormost setae in row J needle-like. Surface of dorsal and marginal shields covered by small oval pits. Marginal shield with smooth and setiform setae (ca. 65–70 µm) anteriorly, and long (ca. 165–170 µm), marginally pilose setae on caudal margins. Postdorsal shield present, with one pair of large, weakly sclerotized, membranous caudal appendices.

Ventral aspect of idiosoma ( Fig. 30 View FIGURES 29 – 32 ). Surface of sternal shield smooth, only two pairs of sternal setae clearly visible, St 4 (ca. 9 µm) smooth and needle-like, situated on level of posterior margins of coxae III, St 5 (ca. 50 µm) needle-like and smooth, placed near basal edges of genital shield. Ventral shield without sculptural pattern. Ventral setae long (ca. 160–170 µm), smooth and setiform, situated at level of anal opening. Three pairs of ventral setae long (ca. 100 µm) and needle-like, situated laterally to postanal setae. Adanal setae ad 1 long (ca. 160 µm), ad 2 and postanal setae short (ca. 50 µm) and needle-like ( Fig. 31 View FIGURES 29 – 32 ). Pedofossae deep, their surface smooth, without separate furrows for tarsi IV. Genital shield linguliform, anteriorly rounded, its surface without sculptural pattern. Stigmata situated between coxae II and III, peritremes M-shaped. Tritosternum ( Fig. 32 View FIGURES 29 – 32 ) with narrow base, laciniae marginally pilose.

Gnathosoma ( Fig. 32 View FIGURES 29 – 32 ). Hypostomal setae h 1 long (ca. 70 µm) and marginally pilose, without smooth branches, h 2 short (ca. 17 µm) and smooth, h 3 short (ca. 14 µm long) and with one apical tooth, h 4 (ca. 18 µm) marginally pilose. Corniculi long and horn-like, with one lateral spine, internal malae longer than corniculi, smooth. Epistome apically pilose. Chelicerae not clearly visible.

Legs. Leg I without ambulacral claws, all legs with pilose setae.

Male. Length of idiosoma 1150 µm, width 750 µm (n= 1). Shape- and dorsal aspect of idiosoma as in female.

Ventral aspect of idiosoma ( Fig. 33 View FIGURES 33 – 35 ). Surface of sternal shield smooth, sternal setae as long as ventral setae (ca. 76–90 µm long), except St 4 (ca. 20 µm), which placed on anterior margin of genital opening. Position of sternal setae as illustrated n Fig. 33 View FIGURES 33 – 35 . Position and shape of ventral setae and ornamentation of ventral shield as in female. Genital shield circular, without sculptural pattern and situated between coxae IV. One pair of lyriform fissures present near lateral margin of genital opening. Tritosternum with narrow base, laciniae subdivided into three marginally pilose branches ( Fig. 34 View FIGURES 33 – 35 ).

Gnathosoma ( Fig. 34 View FIGURES 33 – 35 ). Hypostomal setae h 1 long (ca. 90 µm), marginally pilose, without smooth branches, h 2 short (ca. 20 µm) and smooth, h 3 short (ca. 14 µm long), with one apical tooth, h 4 (ca. 14 µm) marginally pilose. Corniculi long and horn-like, with one lateral spine, internal malae longer than corniculi, marginally pilose. Epistome apically pilose and basally serrate ( Fig. 35 View FIGURES 33 – 35 ). Chelicerae not clearly visible.

Etymology. The name of the new species refers to the one pair of wing-like, large, weakly sclerotised, membranous caudal appendices.

Remarks. The species is unique in the genus Hutufeideria by the presence of the wing-like caudal appendices.
