Diagnosis: A median, semicircular ridge bearing the interlamellar setae present, behind it a pair of well developed interbothridial tubercles present. Sensillus long, curved backwards. Surface of notogaster with polygonal pattern consisting of roundish tubercles. All notogastral setae flagellate, varying in length.

Material examined: Holotype: Thailand, Province Prachin Buri, Sakaerat Research station.

02. 06. 2001. Leg. E. HORVÁTH & GY. SZIRÁKI (As-798). Holotype (1742-HO-2007): HNHM.

Measurements: Length of body: 335 µm, width of body: 187 µm.

Prodorsum: Rostrum conical, rostral setae setiform, barbed, arising on small tubercles; lamellar setae smaller than rostral ones, barbed, originating near to them, located also on the pair of bigger tubercles. No laths or crests in the lamellar region, but a semicircular ridge, with a pointed median apex exist on it medially. Behind of this ridge a pair of well developed tubercles present basally, directed posteriorly. Interlamellar setae very short, dilate, also well barbed. Bothridium angular posteriorly, sensillus long, their outer margin simply serrate.

Notogaster: Surface of notogaster ornamented by small, round tubercles, arranged in typical polygonal pattern (Fig. 18). All notogastral setae flagellate, their distal part very thin, sometimes broken. Anterior two pairs much shorter than the others.

Lateral part of podosoma: Behind the rostrum, the prodorsal surface excavated in lateral view (Fig. 22). Pedotecta 1, 2 and 3 large, latter ones rounded laterally. Discidium also large. Setae 1c arising on the surface of pedotecta 1.

Ventral parts (Fig. 19): Infracapitulum large, covered by secretion tubercles, its setae with long branches (Fig. 20). Epimeral surface covered by minute tubercles, apodemata or epimeral borders hardly observable. A pair of semicircular ridge present on epimere IV. Epimeral setae show different types, thus setae 1b (Fig. 21), 3b, 3c, bearing long branches at their basis, while setae 1c, 2c, 3a, 4b and 4c simple, setiform, only more or less ciliate, in the meantime setae 3a widened, spiniform. Surface of genital and ventral plates irregularly tuberculate, on the surface of ventral plate some distinct polygonal fields observable. Six pairs of simple, thin genital, and two pairs of similar, but longer anal setae present. On the ventral plate 12 pairs, mostly spiniform, dilated and 3 pairs of long, thin setae in posteromarginal position observable. Among the posterior setae, two pairs of them filiform, the median ones bifurcate, or 2 setae arising very near to each other on one side.

Legs: Claw of leg I thinner than those on legs 2–4.

Remarks: The new species is well characterised by the large size of body, the semicircular interbothridial ridge, the flagellate notogastral setae and especially by the bifurcate adanal setae (an 1). These features are unique in the heretofore known species of the genus Eremobelba BERLESE, 1908.

Etymology: I dedicate the new species to Miss EDIT HORVÁTH, my co-worker in the Arachnoidea Collection of the Hungarian Natural History Museum, the collector of this very interesting material.
