Diagnosis.

Paridea (Paridea) sauteri is similar to some individuals of Paridea (Paridea) taiwana having yellow apices of the black elytra but differs by possessing yellow femora and black tibiae (black outer margins of femora and tibiae in Paridea (Paridea) taiwana ).

Males.

Length 4.8-5.5 mm, width 2.9-3.2 mm. General color (Figs 55-57) yellowish brown; antenna dark brown; apex of labrum darkened; elytra black but apex pale yellow; scutellum, meso- and metachoracic ventrites black; tibiae and tarsi blackish brown. Eighth abdominal tergite (Fig. 72) weakly sclerotized, transverse and wide, apical margin truncate, with dense long seta along apical margin. Penis (Figs 68-69) wide, apex pointed, ventrally curved; almost straight from lateral view; endophallic sclerites composed of one pair of elongate and longitudinal sclerites, curved inwards near apex, apex projecting from opening.

Females.

Length 5.5-5.7 mm, width 3.2-3.3 mm. Similar to male; apical margin of last abdominal ventrite smooth, not modified. Gonocoxae (Fig. 70) slender, apex of each gonocoxa with eight setae from apical 1/4 to apex; connection of gonocoxae extremely slender, base slender. Sternite VIII (Fig. 71) weakly sclerotized; apex wide, apical margin slightly emarginate at middle, surface with longer setae near apical margin, and shorter and denser setae on apical margin, spiculum long. Spermathecal receptaculum (Fig. 73) slightly swollen; pump extremely long, strongly curved; spermathecal duct short, stout, shallowly projecting into receptaculum.

Distribution.

Endemic to Taiwan, and with a scattered distribution. The species seems to be allopatric with Paridea (Paridea) taiwana (Fig. 65). For example, it is common in Wulai, northern Taiwan. But no individuals of Paridea (Paridea) taiwana have been found in Wulai.
