Nomenclatural note. Wiesner’s (1988) species concept of waagenorum Horn included one specimen from Khao yai National Park, Thailand. Subsequently, it has been determined that this specimen does not represent waagenorum , and instead, along with six additional specimens is described as a separate species.

Diagnosis. Distinguished by the combination of reddish frons and elytral punctation pattern, several of which are connected in short rows, especially behind the basal humps and near the middle suture.

Etymology. Named after Khao yai, the type locality of this species.

Description. Size: Total length (without labrum) 6.6 mm-8.0 mm, (mean= 7.1 mm, n=7). Head: Shining greenish black, frons reddish. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 396 , female Fig. 397 ) as wide as long, yellowish, with six apical teeth and one lateral tooth. Labial and maxillary palpi yellowish. Antennae extending posteriorally behind elytral shoulders in female, somewhat longer in the males, 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 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 third ( Fig. 391 ). Several of the punctures are connected in short rows, especially behind the basal humps and near the middle suture. Apex with roundish lateral corner and a sutural tooth, slightly recurved between. Maculation composed of a brownish yellow humeral lunule, brownish yellow basal dot and, yellow horizontal central dot which is acutely orientated outwards toward the front and a light yellow apex, reaching the apical humps ( Figs. 392-394 ). The humeral lunule is connected with basal and central dot to a variable degree, the central dot is connected to the light yellow apical lunule at middle suture. Ventral aspect: Venter black, ventrites with small brownish lateral margin. Legs yellowish, hind femora, tibiae and tarsomeres somewhat darker distally. Aedeagus: ( Fig. 395 ) slightly curved, rounded distally, total length 1.7 mm.

Distribution. Thailand (Nakhon Ratchasima).
