Type material.
Holotype, 1♂, Borneo Sabah, Mt. Kinabalu Nat. Pk. HQ Silau-Silau, Tr. 1550 m, 2. IV. 1988, [B171], A. Smetana, MHNG ENTO 00008954 (MHNG).
Etymology.
This species epithet is in honour of the collector of its holotype, A. Smetana, Ottawa Canada.
Description.
Dorsal and ventral surface almost brown (Fig. 5c). Antennae almost yellowish-brown, antennomeres V–XI blackish. Propygidium and pygidium paler than other ventrite. Legs brown to yellowish-brown; tarsi paler than tibiae and femora. Head, pronotum, and elytra sparsely and finely pubescent.
Head with eye width almost the same as interocular distance. Punctuation sparse and fine.
Pronotum wider than long. Punctuation sparse and fine, as on head. Scutellum with slightly exposed apex.
Elytra longer than wide, widest at basal sixth, lateral margins sharply narrowed apically, minutely serrate at inner part of posterior margin. Punctuation fine and sparse as on pronotum. Sutural striae interrupted at basal third.
Hypomeron and lateral portion of mesoventrite smooth. Lateral portion of metaventrite finely and sparsely punctate. Metanepisternum about four times as long as wide, without longitudinal line. Mesepimeron almost as long as wide. Metacoxa about six times as wide as metacoxal process. Ventrite I sparsely and finely punctate.
Protarsomere V 2.5 times as long as each I–IV. Mesotarsomere I about twice as long as II; II 1.2 times as long as each III and IV; V 1.5 times as long as each III and IV. Metatarsomere I about three times as long as each II and III; each II and III 1.1 times as long as IV; V about twice as long as IV.
Protarsomeres I–III possibly with tenent setae, but invisible at × 80 magnification, not enlarged. Aedeagus about 0.5 mm long; parameres symmetrical, with moderately widened apical section slightly longer than third of total parameral length; internal sac with straight, evenly wide flagellar sclerite (Fig. 8b).
Female. Unknown.
Measurements
(n = 1). Length (PL+EL): 1.53 mm, PW: 0.85 mm, EW: 0.88 mm, HW: 0.35 mm, ID: 0.15 mm, PL/PW: 0.62, EL/EW: 1.14. Approximate ratio of each antennal segment in length (width) (n = 1); II 1.5 (0.5): III 1.0 (0.2): IV 1.1 (0.3): V 1.3 (0.2): VI 1.3 (0.2): VII 1.7 (0.3): VIII 1.5 (0.3): IX 1.8 (0.3): X 1.7 (0.4) [XI deformed].
Distribution.
East Malaysia: Sabah.
Remarks.
This species is similar to Xotidium mauritianum (Vinson) and Xotidium meridionale sp. n. in the reduced sutural striae, but may be easily distinguished from them by the simple sclerite of the male genitalia.
