Sathytes shihongliangi  sp. nov.

( Fig. 4View FIGURE 4)

Type material. Holotype: EAST MALAYSIA: ♂, ‘ Borneo: Sabah, Keningau District, Jungle Girl Camp , N5.4430, E116.4512, 1182 m, Shi H.L., Liu Y. lgt., light trap, Ins. Zoo., CAS. 2016. IV.27 ’ ( IZCAS)GoogleMaps  . Paratypes: EAST MA- LAYSIA: 2 ♂♂, same label data as holotype, except for ‘2016. IV.26  ’ ( IZCAS, SNUC).

Diagnostic description. Male. Body ( Fig. 4AView FIGURE 4) dark reddish-brown, mouthparts and legs paler. Body length 2.35–2.54 mm. Head slightly wider than long, length from anterior margin of clypeus to base 0.48–0.49 mm, width across eyes 0.52–0.53 mm. Each eye composed of about 30 facets. Length of eyes (0.24 mm) / length tempora (0.09 mm) approximately 2.7:1. Length of antennae 1.22–1.29 mm; club ( Fig. 4BView FIGURE 4) formed by antennomeres 9–11; antennomere 9 ( Fig. 4CView FIGURE 4) sub-quadrate, semi-membranous apophysis at basal third on mesal surface; antennomere 10 transverse, obconical; antennomere ( Fig. 4B, 4DView FIGURE 4) approximately 1.8 times as long as wide, with one distinct subbasal projection. Pronotum about as long as broad, length along midline 0.52–0.56 mm, maximum width 0.51–0.53 mm. Elytra transverse, length along suture 0.81–0.83 mm, maximum width 1.00 mm. Abdomen widest at tergite 1 ( IV), and narrowing apically; mid-length of dorsally exposed part 0.58–0.66 mm, maximum width 0.86-0.87 mm. Length of aedeagus ( Fig. 4EView FIGURE 4) 0.22 mm; median lobe almost symmetric, slightly narrowing from base toward apex.

Female. Unknown.

Comparative notes. Sathytes shihongliangi  is morphologically very similar to S. punctiger Westwood  from Sarawak, and may be separated from it only by the relatively more elongate antennomeres 9 and 11, and the aedeagal form, as well as the more basal position of the apophysis of antennomere 9.

Distribution. East Malaysia: Sabah.

Etymology. The new species is named after Hong-Liang Shi, who was one of the collectors of the new species.
