Nomenclatural note. A male of waagenorum from Myanmar, preserved in MSNG, bears the label “ Therates concinnus Gestro, 1888 , teste R. Gestro, 1893” and was the specimen upon which Wiesner (1988:15, f. 61, 297, 394) erroneously based his concept of Therates concinnus . After carefully studying the type of Th. concinnus Gestro on loan from MSNG, I determined that Therates differens , as described by Sawada and Wiesner (1999) is conspecific with Th. concinnus , and thus place it into synonymy herein.

Diagnosis. Distinguished by the combination of elytral maculation with large angular shaped central dot, confluent humeral lunule and basal dot.

Description. Size: Total length (without labrum) 7.2 mm- 9.1 mm, (mean=8.1, n=88). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 97 , female Fig. 98 ) as wide as long, yellowish, with six apical teeth and one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind elytral shoulders in female, somewhat longer in the male, 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. Clypeus glabrous. Frons smooth with one shallow bump in the middle between and two shallow bumps in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, as long as wide, constricted in front and at back, transverse furrows strong, middle line and lateral lines nearly obsolete, middle line with several transverse short branches. Elytra: Shining brownish black, with basal and apical humps, distinctly punctate in front, shallower in the apical half ( Fig. 90 ). Apex with roundish lateral corner and a sutural tooth, recurved between. Maculation composed of a brownish yellow humeral lunule, a brownish yellow basal dot, a large yellow horizontal central dot with angular shape, and a light yellow apex reaching the apical humps ( Figs. 91-95 ). The humeral highly variable, often connected to the basal dot. In rare instances the humeral lunule is connected to the central dot at the middle of the suture. Ventral aspect: Venter black, ventrites with small brownish lateral margin. Legs yellowish, femora, tibiae and tarsomeres of metathoracic legs somewhat darker distally. Aedeagus: ( Fig. 96 ) curved, with pin shaped and produced tip, total length 1.8 mm.

Distribution. Myanmar (Tanintharyi = Tenasserim), Thailand (Chiang Mai), Laos (Phongsali Louangnamtha, Bokeo, Oudomxai, Louangphrabang, Houaphan), Vietnam (Lao Cai, Hoa Binh, Nin Binh).
