Diagnosis. This new species can be recognized among congeners of Sadoletus by a combination of the following characters: head, anterior lobe of pronotum, mesepisternum, metepisternum, and basal half of scutellum reddish brown to blackish (Fig. 4); antennae brownish yellow (Fig. 4); evaporatrium blackish; peritreme yellowish; scutellum weakly tumid in basal one-third (Fig. 4); corium whitish to brownish yellow, with dark small spot on apex (Fig. 4); tibiae with dark annulations (Fig. 4); each laterotergite pale brown anteriorly and blackish posteriorly (Figs. 4, 23); paramere widened at apical one-third, with acute at apex (Fig. 25); female abdominal sternite VII with posterior margin entirely concave toward midpoint (cleft on midline) (Fig. 7); and ovipositor less than 1.0 mm in length, not reaching sternite VI in rest (Fig. 7). Body length 4.25–5.50 mm.
Description of genitalia. Male: Pygophore (Fig. 24) nearly globous in dorsal view, covered with fine setae; dorsal aperture more than one-third as wide at middle as pygophore, with collar along anterior margin. Paramere (Fig. 25) twisted at basal one-third, widened at apical one-third, acute and curved at apex, covered with several erect setae in basal one-third and a few short setae apically. Phallosoma (Figs. 26, 27) 1.5 times as long as its width in ventral view. Endosoma (Figs. 28, 29) covered with fine spines near middle.
Females: Ovipositor (Fig. 7) 0.75 to 0.85 mm in length, not reaching sternite VI. Spermatheca (Fig. 22) rounded.
Distribution. Japan: the Ryukyus (Miyako-jima, Ishigaki-jima, Kohama-jima, Iriomote-jima, Yonaguni-jima Islands); the Philippines. Previous records as S. valdezi from Nakano-shima Island (Hidaka 1959) and Tokunoshima Islands (Tomokuni 1989) arguably correspond to S. ryukyuensis sp. nov. (see also “Remarks” in the previous species).
Remarks. This species is similar in general appearance to S. ryukyuensis sp. nov., from which it can be distinguished by the paler, whitish to brownish yellow coria, the bicolored laterotergites, the globe pygophore in dorsal view, the smaller parameres with the apex acute and curved, and posterior margin of female abdominal sternite VII entirely concave toward midpoint (cleft on midline).
Biological notes. Adults of S. valdezi have often been found on trees of Ficus virgata Reinw. ex Blume (Moraceae) with fruits. This tree species might be considered to be one of host plants of S. valdezi.
