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.
