Description. Medium-sized Naddia species. Body elongate, almost totally black; head and pronotum black; most pubescence of dorsal side of head and pronotum brownish-black, reflecting silvery or golden, depending on angle of light; elytra black, with reddish-brown humeral angles, reddish-brown color sometimes extending along margin of scutellum, almost reaching suture; elytral pubescence dark brown mixed with scant golden pubescence, with more obvious patches of golden or silvery pubescence forming a characteristic pattern on disc, but with denser arrangement near shoulders and laterally at mid length of elytra (recognition of these pubescence patterns requires proper, diffused lighting); first 4 visible abdominal tergites (tergites 3–6) each with a patch of black subtomentose pubescence in middle, that on tergite 3 very small, on tergite 4 occupying about 1/3 of tergite width, gradually becoming slightly wider on tergites 5 and 6; remaining area of tergites 3 and 4 covered by mixture of reddishgolden, silvery and brown pubescence; tergite 5 with a pair of patches of golden and silvery pubescence in anterior half, delimiting black patch and dark-brown pubescence in posterior half; tergite 6 with a narrow transverse band of silvery or pale golden pubescence; maxillary and labial palpi brown; antennae black, with distal one or three segments with variably extensive, obscurely reddish-brown margins; legs black, tibiae covered with dense lightyellow pubescence; protarsi bright reddish, starkly contrasting with tibiae, meso- and metatarsi with proximal segments dark, becoming paler distally, rarely also meso- and metatarsi entirely reddish.
Head wide and very flat, subparallel-sided, with lateral margins strongly protruding posteriad ( Fig. 1-2 A View FIGURE 1-1 View FIGURE 1-2 ); eyes moderately protruding, distinctly shorter than tempora in dorsal view (ratio 0.73). Punctation and pubescence dense and strong, punctures almost contiguous; interspaces narrow, almost ridge-like, shiny, without microsculpture; no impunctate midline present on head disc. Antennae short, bent backward hardly reaching midlength of pronotum; segment 3 distinctly longer than segment 2 (ratio 1.68), segment 4 to 10 gradually becoming wider towards apex, 5–10 slightly asymmetrical, last segment almost oval, narrower than segment 10 ( Figs. 1-1 F, 1-2 J View FIGURE 1-1 View FIGURE 1-2 ). Last segment of maxillary palpi robust, with only a few extremely short setae; last segment of labial palpi subfusiform, sparsely setose.
Pronotum nearly horseshoe-shaped and convex in middle, almost as long as wide (ratio 1.02), slightly narrower than head in dorsal view (ratio 0.93); posterior half with widely rounded lateral and posterior margin. Punctation and pubescence almost the same as on head, slightly finer; with very short and narrow indication of an impunctate midline in anterior fourth and posterior third of pronotum disc, rarely rudimentary. Scutellum triangular, densely covered with black velvety pubescence. Elytra nearly quadrate, slightly dilated posteriad and slightly depressed at base; elytral length along suture shorter than the length of pronotum along midline (ratio 0.68), but longer than that along lateral sides (ratio 1.17); punctation much finer and denser than that on head disk. Wings fully developed.
Abdomen elongate and gradually narrowed posteriad; surface finely and very densely punctate in areas of subtomentose pubescence, more coarsely punctate and with wavy microsculpture in remaining areas on tergites 3–6 (first 4 visible tergites); tergite 7 with fine and dense punctation in anterior half, with larger but markedly sparser punctation in posterior half; tergite 8 with uniform punctation as in posterior half of tergite 7.
Male. Abdominal sternite 7 medially with a broad and shallow fovea bearing long and dense setae; posterior margin only slightly emarginate in middle. Sternite 8 with narrow and shallow medioapical emargination ( Figs. 1-1 E, 1-2 E View FIGURE 1-1 View FIGURE 1-2 ). Sternite 9 elongate, with apical emargination narrowly obtuse ( Figs. 1-1 D, 1-2 H View FIGURE 1-1 View FIGURE 1-2 ). Tergite 10 relatively long, almost evenly narrowed toward shovel-like apical margin, sparsely setose ( Figs. 1-1 G, 1-2 F View FIGURE 1-1 View FIGURE 1-2 ). Aedeagus elongate, almost symmetrical; in ventral view median lobe slightly narrowed towards apex and weakly widened before rounded apex ( Figs. 1-1 B, C, 1-2 B, C, D View FIGURE 1-1 View FIGURE 1-2 ); paramere relatively well developed for Naddia , but very flat, reaching about half length of median lobe.
Female. Second gonocoxite with wide basal portion and relatively narrow apical portion ( Figs. 1-2 I View FIGURE 1-1 View FIGURE 1-2 ). Tergite 10 with shovel-like apical portion, sparsely setose ( Fig. 1-2 G View FIGURE 1-1 View FIGURE 1-2 ).
Distribution. The new species is widely distributed in southeastern China: Hong Kong, Guangdong, Fujian, Zhejiang, Jiangxi, Hubei.
Diagnosis. Naddia flavipes belongs to the atripes species group. It is similar to Naddia hujiayaoi Xia, Tang & Schillhammer, 2022 , which also has bright reddish protarsi and a similar habitus, but differs in the broader head with somewhat larger eyes, antennal segment 11 almost oval (not obliquely subtruncate and with pointed outer angle as in the latter species), different pattern of elytral pubescence patches, much narrower and denser black subtomentose patches on abdominal tergites 3–6, abdomen generally duller than in N. hujiayaoi ; the apex of the aedeagus is more rounded.
Etymology. The species epithet flavipes is a combination of the Latin words flavus, -a, -um (yellow, golden) and pes, -dis (leg), and refers to the contrasting reddish-yellow color of the tarsi.
