Diagnostic description. Male. Body ( Fig. 6A View FIGURE6 ) dark reddish-brown, mouthparts and tarsi paler. Body length 1.95–2.10 mm. Head moderately wider than long, length from anterior margin of clypeus to base 0.36–0.39 mm, width across eyes 0.44–0.47 mm. Each eye composed of about 20 facets. Length of eyes (0.14 mm) / length of tempora (0.09 mm) approximately 1.6:1. Length of antennae 1.01–1.04 mm; club ( Fig. 6B View FIGURE6 ) formed by antennomeres 9–11; antennomere 9 ( Fig. 6C View FIGURE6 ) slightly transverse, semi-membranous apophysis at nearly upper half on mesal surface; antennomere 10 strongly transverse, obconical; antennomere 11 ( Fig. 6B View FIGURE6 ) about 1.9 times as long as wide, with two truncate basal protuberances, the more basal one covered with two tufts of specialized setae at apex ( Fig. 6D View FIGURE6 ). Pronotum slightly longer than wide, length along midline 0.45–0.51 mm, maximum width 0.43–0.49 mm. Elytra transverse, length along suture 0.61–0.68 mm, maximum width 0.76–0.77 mm. Abdomen widest at tergite 1 ( IV), and narrowing apically; mid-length of dorsally exposed part 0.48–0.54 mm, maximum width 0.66–0.68 mm. Length of aedeagus ( Fig. 6E View FIGURE6 ) 0.25 mm; median lobe almost symmetric.
Female. Similar to male in size. Body length 1.98–2.03 mm. Head slightly wider than long, length from anterior margin of clypeus to base 0.42–0.43 mm, width across eyes 0.45–0.46 mm. Each eye composed of about 20 facets. Length of eyes (0.12 mm) / length of tempora (0.05 mm) 2.4:1. Length of antennae 0.89–0.93 mm. Pronotum slightly longer than wide, length along midline 0.46–0.49 mm, maximum width 0.44–0.47 mm. Elytra moderately transverse, length along suture 0.58–0.62 mm, maximum width 0.75–0.76 mm. Abdomen widest at tergite 1 ( IV), and narrowing apically; mid-length of dorsally exposed part 0.53–0.58 mm, maximum width 0.71–0.73 mm.
Comparative notes. Sathytes similis is morphologically close to S. paulus Yin & Li and S. wuyishanus Yin & Li in the form of antennomeres 9 and 11, and may be separated from both by the much larger body size (1.95–2.10 mm vs. 1.59–1.66 mm of S. paulus , and 1.54 mm of S. wuyishanus ), and the relatively more transverse antennomere 2 in relation to antennomere 3.
Distribution. China: Zhejiang, Jiangxi.
Etymology. The new specific epithet ‘ similis ’ refers to the morphological similarity between the new species and its congeners.
