Scirtes rufotinctus Champion, 1918: 262 .

Type material. Holotype ( BMNH): 1 female, “ Mt. Matang , W. Sarawak. G.E. Bryant. 13.2.14. 1000 m ”; “ Scirtes rufotinctus Ch ”; “ ♀ ”; “96.96”; “464”; “Type”; “(…)” illegibly handwritten by Champion.

Description. Female. Body oblong, slightly flattened. Coloration of head, pronotum, and scutellum yellow; legs yellowish-brown with slightly infuscate pro- and mesotibia; mouthparts dark brown, antennomeres 1–3 yellow, 4–8 black, remaining missing in the holotype; elytra red.

Head of moderate size, slightly convex dorsally, finely punctate; clypeus long, expanded antero-laterally, gently arcuate in front margin. Eyes moderate in size, prominent; the distance between the eyes ca. 2.1 times as long as the maximum diameter of an eye. Antennae filiform, antennomeres 9–11 missing in the holotype. Pronotum slightly convex in mesal part of the disk, finely punctate; antero-lateral angles somewhat acute, projecting anteriorly; front and lateral margins gently arcuate; postero-lateral angles right-angled; posterior margin slightly bisinuate; PW / PL 2.31 . Scutellum relatively small, finely punctate, equilateral-triangular. Elytra oblong-oval, widest at the middle, punctation sparser than on pronotum; humeri elevated; EL/EW 1.39; EL/ PL 4.25 ; EW/ PW 1.32 ; TL/EW 1.71. Apical parts of elytra without excitators. Legs relatively long. Hind tibial spurs well developed, dorsal spur slightly curved, 2.0 times longer than ventral one, ca. 0.7 times as long as hind tarsomere 1. Sternite VII with a pair of small foveae in the middle of its length. Ovipositor long, prehensor small, consisting of a plate forming a small semicylindrical structure. Bursal sclerite indistinct .

Male. Unknown.

Measurements. Female (n = 1): TL 4.20 mm; PW 1.85 mm; PL 0.80 mm; EL 3.40 mm; EW 2.45 mm.

Distribution. Borneo Isl. ( Sarawak).

Notes. Yellow dorsum with intensively red elytra, lack of excitators and contrasting yellow-black antennae make identification of this species unmistakable.
