( Fig. 1 View Fig )

Metadentobunus formosae Roewer, 1915: 149 View in CoL , fig. 81 (type locality: Lugang, Taiwan); Roewer 1923: 949, fig. 1084 (Lugang, Taiwan); Roewer 1955: 85 (Lugang, Taiwan); Suzuki 1970: 33 (list); Wang 1953: 509 (list); Li and Song 1993: 241 (list).

Metadentobunus formosae formosae View in CoL - Suzuki 1977: 137 (Rokko, Taiwan).

Type material: Holotype: 1 $ ( SMF 9801162- RI/ 1162-66), Rokko, Formosa (= Lugang, Changhua, Taiwan).

Diagnosis: Ocularium rectangle, length larger than width, constricted basally, with one pair of sharp and long spines at frontal margin ( Fig. 1 View Fig C- D). Frontal spines of ocularium with tubercles. Patella of pedipalp without inner apophysis at tip ( Roewer 1915). Genital operculum protruding from frontal margin ( Fig. 1H View Fig ).

Redescription: Female holotype. Dorsal surface of body granulated. Abdomen with 1 short median spine on the second tergite. Supra-cheliceral lamellae tipped with 4-5 small tubercles ( Fig. 1G View Fig ). Ocularium rectangle ( Fig. 1 View Fig C-D), length larger than width, constricted basally, with one pair of frontal spines, sharp and long. Frontal spines of ocularium finely granulated. All free sternites and genital operculum smooth. Genital operculum protruding from frontal margin ( Fig. 1H View Fig ). Surface of all coxae with scattered coarse granules. Coxa I and IV with a row of humps anteriorly and posteriorly; Coxa II and III with a row of humps anteriorly.

Chelicera. Basal segment with 5-9 tubercles dorsally. Distal segment with setae dorsally, outer side smooth, inner side with setae ( Fig. 1 View Fig E-F).

Pedipalp. Femur with numerous denticles ventrally.

Legs. Trochanters mound-shaped ( Fig. 1 View Fig A-B), femora II with two false articulations, tarsus longer than tibia.

Ovipositor. Unexamined.

Measurements: Holotype female ( SMF 9801162-RI/1162-66): Total length of body 6, femur length of leg I-IV 8:15.5:7:12. Length of leg I-IV 33:67:29:45.

Coloration: Not available.

Distribution: Lugang, Changhua, central Taiwan ( Fig. 7 View Fig ).

Remark: Metadentobunus formosae is similar to M. garampiensis , except for the morphology of its pedipalpal patella. The inner tip of pedipalpal patella of M. garampiensis has an apophysis at the inner tip of pedipalpal patella, but M. formosae does not.
