( Figs 17, 22, 37)

Zyras (Zyras) pallipyga PACE, 2008: 150 f.

Type material examined: Holotype : “ / SABAH: E Mt. Kinabalu , 1150 m, rte Ranau – Kota Kinabalu, 24.V.1987, Burckhardt - Löbl / Holotypus Zyras pallipyga mihi, det. R. Pace 2000 / Zyras pallipyga n. sp., det. R. Pace 2000 / MHNG ENTO 00010003 / Zyras pallipyga Pace , det. V. Assing 2017 ” ( MHNG).

Comment: The original description is based on a unique female from “ Sabah, E Mt. Kinabalu, ..., Ranau– Kota Kinabalu ” ( PACE 2008) .

Additional material examined: Malaysia: 1 , Sabah, 50 km E Kota Kinabalu, Crocker Mountains, Gg. Emas , 16–27.IV.1993, leg. Jenis (cAss) .

Redescription: Small species; body length 4.6–4.8 mm; length of forebody 2.4 mm. Coloration ( Figs 17, 22, 37): head and pronotum reddish; elytra yellowish-red, with or without the postero-lateral portions slightly darker; abdomen with segments III–VI reddish to pale reddish-brown and segments VII–VIII yellowish red; antennae brown to dark-brown with antennomeres I–II pale-reddish and XI dark-reddish; maxillary palpi yellowish-red with the apical palpomere yellow.

Head ( Fig. 22) distinctly transverse, median portion extensively impunctate; punctures in lateral portions moderately coarse and sparse. Eyes moderately large, slightly longer than postocular region in dorsal view. Antenna ( Fig. 17) short and clavate, 1.20–1.25 mm long; antennomere IV disc-shaped, approximately twice as broad as long; antennomeres V–X disc-shaped, of gradually increasing width and increasingly transverse, X approximately three times as broad as long, and XI broad and short, approximately as long as the combined length of IX and X.

Pronotum ( Fig. 22) distinctly transverse, approximately 1.2 times as broad as long and 1.2 times as broad as head, broadest near anterior angles, moderately convex in cross-section; lateral margins straight in posterior two-thirds in dorsal view; posterior angles weakly marked; punctation sparse, moderately coarse, and irregularly distributed; impunctate median band broad.

Elytra ( Fig. 22) approximately 0.9 times as long as pronotum; punctation very sparse and fine, posteriorly even sparser. Hind wings present. Legs relatively short; metatarsomere I rather short, shorter than the combined length of II–IV.

Abdomen ( Fig. 37) narrower than elytra, with deep anterior impressions on tergites III–V; anterior impressions of tergites III–V and anterior portion of tergite VI each with a transverse row of defined and not very coarse non-setiferous punctures, with a lateral setiferous puncture on either side, and with numerous fine setiferous punctures at posterior margins; tergites IV–VI additionally with a median pair of coarser setiferous punctures; tergite VII only with scattered and very fine non-setiferous punctures anteriorly and with two transverse series of setiferous punctures bearing long dark setae posteriorly, posterior margin with palisade fringe; tergite VIII with setiferous punctation only in posterior fourth, posterior margin convex.

: unknown.

: posterior margin of sternite VIII distinctly concave in the middle.

Comparative notes: This species is characterized by small size, its coloration, conspicuously clavate and short antennae, very sparse punctation of the pronotum and elytra, and a distinctive punctation pattern of the abdomen (defined non-setiferous punctures present on tergite VI, but not on tergite VII).

Distribution: The currently known distribution is confined to two localities to the east of Mount Kinabalu, Borneo ( Malaysia: Sabah). The holotype was collected at an altitude of 1150 m.
