Metadentobunus formosae formosae - 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 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 ). 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 ). Ocularium rectangle ( Fig. 1 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 ). 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 E-F). Pedipalp. Femur with numerous denticles ventrally. Legs. Trochanters mound-shaped ( Fig. 1 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 ). 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.
