Description
Holotype Worker: TL: 2.27 mm, HL: 0.66 mm, HW: 0.46 mm, SL: 0.42 mm, ML: 0.31 mm. FCD: 0.20 mm, PW: 0.28 mm, WL: 0.66 mm, CI: 70, MI: 47. SI: 91, FCI: 43, MSI: 42. Head as in Fig. 35, microreticulate sculpture, with short, narrowly spatulate hairs on cranium; in full face view, dorsolateral borders of head posteriorly with a pair of long flagellate hairs in full face view. Mandible hook-like at extreme apex, slender in full face view, external margin very shallowly and evenly convex; internal margin almost straight. Preapical teeth of mandible prominently spiniform; apical fork with 2 spiniform teeth and 2 intercalary denticles (Fig. 37). Anterior clypeal margin transverse. Antenna 6-se- gmented, in ratio of 15: 3.2: 1: 1: 4.8: 11 in length from base; scape mircoreticulate. with a row of narrowly spatulate hairs; 2 nd segment 2 X as long as wide; 3rd and 4 th segments each shorter than broad; 5th segment 2.8 X as long as wide; apical segment 5 X as long as wide. Eye relatively small, 0.04 mm in maximum diameter, consisting of 6 ommatidia. Dorsum of promesonotum smooth and shining in most part and with sparse, short curved hairs and narrowly spatulate hairs. Two pairs of long flagellate hairs present on dorsum of pronotum (Fig. 36). Mesopleuron, metapleuron and mota- notum smooth and shining in most part Propodeal lamellae well developed; poste- rior border straight and posterodorsal corner dull angulate in lateral view. Petiole peduncle long and node convex, microreticulate sculpture, with erect hairs. Spongiform appendages of pedicel segments well developed. First gastral tergite smooth and shi- ning with more than 5 pairs of erect hairs. Body yellowish brown.

Discussion
Remarks: This new species is closely related to S. godeffroyiHNS Mayr, but is separable from it by the following charac- ters: (1) smaller size (TL>2.35 mm in godeffroyiHNS, TL>2.22 mm in tradaHNS); (2) pronotum, mesonotum and propodeum smooth and shining in most part (micro- reticulate in godeffroyiHNS); (3) 1st gastral tergite without long flagellate hairs, erect hairs present (with about 7 pairs of hairs in godeffroyiHNS); (4) eye relatively small and consisting of 6 ommatidia (more than 10 ommatidia in godeffroyiHNS). Only 1 specimen was collected from Wulai in northern Taiwan.
