(Figs. 1D, 3E)
Description of holotype Size: 6.2 mm. BODY. Shape: cuneiform, Build: slender, Color (dorsally): unicolored. HEAD. Modification: strongly convex, Medial impression: shallow. Vertex Medial impression: present, Sculpture elements: rugae, Sculpture aspect: arcuate. Eyes Size: subequal or larger than width of vertex (dorsal view), Lower margin: in line or below antennal socket, Median orbit: converging ventrally. Antennae Serration: from antennomere 4. PRONOTUM. Shape: visually transverse, Sides: slightly arcuate, Maximal width: at posterior margin, Anterior margin: narrower than posterior. Anterior lobe Development: obvious, Shape: arcuate, Width: broad, Position: projecting beyond anterior angles. Posterior angles Shape: obtuse, Apex: sharp. Disk Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): deep, Lateral impressions (width): broad. Prehumerus Development: carinal, Shape: arcuate, Extent: to 1/3 of pronotal length, Anterior end: distant from lateral carina, Posterior end: distant from posterior angle or margin, Arc: weak. Lateral carinae Interspace: narrow, Convergence: moderate, Junction: present, Narrowest point: at posterior 1/5–1/4 of marginal carina. ELYTRA. Color: unicolored, Humeral carina: absent. Apices Arrangement: conjoint, Shape: arcuate, Modifications: margin obviously denticulate. Tomentum Pairs of tomentose spots: medial, apical. STERNUM. Pubescence Strip of erect pubescence: absent. Prosternal lobe Size: large, Position to sternum: markedly declivous, Distal margin: subtruncate. Prosternal process Width: wide, Shape: subparallel, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: flat, Projection (length): protruding distinctly beyond angles. Metasternum Metasternal projection: flat. ABDOMEN. Basal ventrite Modifications: without modifications. Pygidium Apical margin: arcuate. Last ventrite Shape: with narrow apex. Sternal groove Extent: on all ventrites, Shape on apex of last ventrite: subangulate. LEGS. Metafemora Modifications: lower margin with row of obvious whitish setae. Metatarsus Length to metatibia: distinctly shorter. Metatarsomere 1 Length to following tarsomeres: longer than 2–3 but shorter than 2–4. GENITALIA. Aedeagus Symmetry: symmetric, Shape: subparallel.
Variability. Size: 6.2–7.3 mm. Sexual dimorphism. Frons golden–green (male) or golden–orange (female). Eye larger than width of vertex (male) or subequal to width of vertex (female) dorsal view). Aedeagus (Fig. 3E).
Diagnosis. The species is distinctive by slender body and obviously dentate elytral apices (Fig. 1D).
Type material. Type locality. Thailand, Mae Hong Song province, Soppong-Pai, alt. 1800 m. Type specimens. Holotype ♂, 1 ♀ paratype (EJCB): “ Thailand, 1– 8.5.1993, Soppong-Pai, 1800 m, Pacholátko & Dembický leg.”; 2 ♀ paratypes (EJCB): “ Lao-N, Phongsaly prov., 21°41'–2'N, 102°06'–08'E, Phongsaly env., 28.v.–20.vi.2003, 1500m, P. Pacholátko leg.”
Distribution. LAOS: Phôngsali. THAILAND: Mae Hong Son.
Etymology. The combination of Latin plus, pluris (more, several, many) and dens (tooth, spike). It referes to obviously dentate elytral apices of the species.
