Type depository. Holotype female in SDEI.

Type status. Holotype female! Type labels: “ Tonkin, Montes Mauson, April, Mai 2-3000’, H. Fruhstorfer ” [printed]; ”Holotypus“ [printed, red]; “rugifer mihi” [handwritten, light yellow, with black borders]; “Type!, Dr. W. Horn “ [printed, with black borders].

Diagnosis. Distinguished by the combination of short humeral lunule, extreme medial orientation of the central dot, and the male with the two distal antennomeres enlarged.

Re-description. Size: Total length (without labrum) 6.7 mm- 8.2 mm, (mean= 7.6 mm, n=10). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 237 , female Fig. 238 ) barely wider than long, blackish laterally, yellowish in the center, with six apical teeth one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind elytral shoulders in male, somewhat shorter in the females, scape with a single apical bristle, antennomeres 2 to 5 glabrous, antennomeres 6 to 11 finely and evenly pubescent; scape yellowish above, black on underside, all the other antennal segments brownish, lighter in the males, the two distal segments darker. Two distal segments obviously enlarged in males. Clypeus glabrous. Frons smooth, with a transverse furrow in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, as long as wide, barely more constricted in front than at back, transverse furrows strong, middle line and lateral lines nearly obsolete, middle line with several transverse short branches. Elytra: Shining black, in some specimens transparent brown apically, with basal and apical humps, distinctly punctate in front, shallower in the apical half ( Fig. 232 ). Apex with angular lateral corner and sutural tooth, slightly recurved between. Maculation yellow, composed of a short humeral lunule, basal dot, and angular central dot that is acutely angled inwards toward the suture ( Figs. 233-235 ). Ventral aspect: Venter black. Metatibiae bicolored, basal third blackish, remainder yellow, tarsi and femora yellow, tarsomeres darker distally. Aedeagus: ( Fig. 236 ) cuved, with produced thick tip, total length 1.8 mm.

Distribution. Vietnam (Lang Son, Vinh Phuc, Nin Binh).

Localities. VIETNAM, Nin Binh, Cuc Phuong Nat. Park , 21.-22.v.1996 ( NHMB) , Lang Son, Than Moi ( SDEI) , VIETNAM, Vinh Phuc, Tam Dao , 2.-11.vi.1985 ( JWCG, JMCC) , 27.v.-2.vi.1986 ( ZSMC) , 6.- 20.v.1990 ( JWCG) , v.1990 ( ZSMC) , v.1996 ( JMCC, OSCC) .

Remarks. As stated by Horn (1927: 245, f. 36), the holotype female is an aberrant specimen with individual deformations of the surface of head, pronotum, and elytra - these anomalous deformations were not considered for the updated description.
