Redescription. Following are additions and/ or alterations to the detailed redescription of the genus Sadoletus provided by Ban & Ishikawa (2013) and Gao & Rédei (2017).

Buccula as in Fig. 4a View FIGURE 4 ; metathoracic scent gland as in Fig. 4b, c View FIGURE 4 ; tergites I and II fused; sutures between tergites III–IV straight or slightly curved caudad, IV–V moderately and V–VI strongly or IV–V and V–VI equally curved caudad in the middle area, VI–VII straight or slightly sinuate, and with scent gland scars only between IV–V and V–VI well developed and subequal in width. Outer laterotergite II present, very small; outer laterotergite III narrowed towards base of abdomen, and IV–VI elongated rectangle; distal area of outer laterotergite VII and tergite VII fused. Tergites I–VI with regular dense punctures, and tergite VII with sparse smaller irregular punctures. Sternum covered with very fine punctures, almost indistinct. Trichobothria in full trichobothria complement (3:3:3:3:2); detailed structure of trichobothria as in Fig. 4d, e View FIGURE 4 ; bothrium not sunken below surface of the cuticle and trichomes present, with short spine-like microtrichia.

Ovipositor short, only reaching posterior margin of abdominal sternite VI; abdominal sternite VII short and medially divided fully to its base, with the two halves gradually broadly rounded and flap-like, either leaving a narrow gap in the middle (as in S. bakeri ) ( Fig. 21c View FIGURE 21 ) or the flaps are slightly (for example in S. valdezi ) ( Fig. 6c View FIGURE 6 ) or strongly (for example in S. melasmus ) ( Fig. 13b View FIGURE 13 ) overlapping in the middle, and the sternites III–VI are complete, with their posterior margins entire, almost straight, not divided or narrowed in the middle ( Figs. 3d View FIGURE 3 ; 6b, c View FIGURE 6 ), moderate or weakly concave (Fig. 8e). Pygophore dorsal opening with a well developed median projection on its posterior margin; median projection fused with cuplike sclerite arising from inner side (except in S. laosensis ) ( Figs. 1e View FIGURE 1 ; 19f View FIGURE 19 ).
