Holotype Worker: TL: 2.8 mm, HL: 0.73 mm, HW: 0.67 mm, SL: 0.45 mm, ML: 0.35 mm, FCD: 0.21 mm, PW: 0.34 mm, WL: 0.84 mm, CI: 92, MI: 48, SI: 67, FCI: 31, MSI: 40.
Head as in Fig. 15, microreticulate sculpture, with short, narrowly spatulate hairs on cranium. Posterior portion of head with a row of erect hairs. Mandible hook-like at extreme apex, slender in full face view; external margin very shallowly and evenly convex; internal margin almo- st straight. Preapical teeth of mandible prominently spiniform; apical fork with 2 spiniform teeth, and 2 intercalary den- ticles (Fig. 17). Anterior clypeal margin transverse. Antenna 6-segmented, in ratio of 13: 3: 1: 1: 3.5: 8.5 in length from base; scape microreticulate, with a row of narrowly spatulate hairs; 2nd segment 2 X as long as wide; 3rd and 4th segments each as long as wide; 5th segment 2 X as long as wide; apical segment 4.5 X as long as wide. Eye relatively small, 0.06 mm in maximum diameter, consisting of 8 omma- tidia.
Dorsum of promesonotum microre- ticulate sculpture, with erect hairs pres- ent on dorsum of mesosoma (Fig. 16). Mesopleuron and metapleuron smooth and shining in most part. Propodeum microreticulate sculpture. Propodeal la- mellae well developed.
Petiole peduncle long and node con- vex, microreticulate sculpture, with erect hairs. Spongiform appendages of pedicel segments well developed.
First gastral tergite smooth and shi- ning, with sparse long flagellate hairs. Body yellow.
Paratype: workers Ten paratype workers with the following measurements and indices: TL: 2.70-2.90 mm, HL: 0.71-0.74 mm, HW: 0.66-0.68 mm, SL: 0.44-0.47 mm, ML: 0.34-0.36 mm, FCD: 0.20-0.22 mm, PW: 0.33-0.35 mm, WL: 0.83- 0.86 mm, CI: 90-93, MI: 46-49, SI: 63-67, FCI: 30-33, MSI: 39-42.
Paratype females: Five paratype females with the following measurements and indices: TL: 2.80-3.00 mm, HL: 0.74-0.75 mm, HW: 0.56-0.60 mm, SL: 0.41-0.43 mm, ML: 0.39-0.42 mm, FCD: 0.26-0.28 mm, PW: 0.38-0.39 mm, WL: 0.81- 0.83 mm, CI: 78-80, MI: 51-53, SI: 70-72, FCI: 45-57, MSI: 46-48.
General shape of head and mesosoma as shown in Figs. 18-19. Head and antenn- al scape microreticulate sculpture. Head with narrowly spatulate hairs in cranium; posterior border of head with a row of erect hairs. Compound eye large. Ocelli relatively large, each with blackened callus.
Mesosoma in profile relatively more even dorsally, arching from anteriormost of mesonotum to posteriormost of meta- notum (Fig. 19). Propodeal lamellae well developed. Dorsum of mesosoma with numerous, short erect hairs. Erect hairs sparsely present on dorsa of mesosoma, petiole, postpetiole and 1st gastral tergite.
Holotype: Worker, NANTOU HSIEN: Chitou, 30.XI.1992, CCL.
Paratypes: CHIAI HSIEN: Fenchifu, 7 workers, 3.LX.1992, CCL. ILAN HSIEN: Fushan, 5 females, 58 workers, 9.X. 1992, CCL. NANTOU HSIEN: Chitou, 1 female, 12 workers, 30.XI.1992, CCL (from the same nest as the holotype). TAIPEI HSIEN: Wulai, 1 worker, 2.X.1992, CCL.
Type depository: The holotype is preserved in the NTU, and paratypes in NTU and TARI.
Etymology: The species is named from the Latin "hispidus", which means hair.
Remarks: This new species resembles S. solifontis Brown HNS , but is distinguished from the latter by the lower number of hairs on the 1st gastral tergite, and much more developed propodeal lamellae. In female, mesosoma in profile is more even dorsally than that in S. solifontis HNS .
