Prothemus kantnerorum sp. nov.

( Figs. 82-83 )

Type locality. Laos, Hua Phan Province, Ban Saluei, Mt. Phu Phan, 20°13′N 103°95′E, 1300- 2000 m a.s.l.

Type material. HOLOTYPE: J, ‘ Laos, Hua Phan prov., Ban Saluei, Mt. Phu Phan , 20°13′N 103°95′E, 1300-2000 m, 6.-17.v.2004, F. & L. Kantner lgt.’ ( NMPC) . PARATYPES: same data, 3 JJ 6 ♀♀ ; same locality data, P. Kresl lgt., 2 JJ 2 ♀♀ (all NMPC) ,

Description. Coloration. Head terra-cotta, mouthparts sienna, antennae black, antennomere 1 excluding apex and base of antennomere 2 terra-cotta. Prothorax, meso- and metasternum, scutellum, elytra and last abdominal segment terra-cotta, rest of abdominal sternites sooty with narrow yellow borders. Coxae, femora and basal portions of tibiae terra-cotta, rest of legs black, claws terra-cotta.

Male. Eyes large, protruding, head across eyes moderately narrower than pronotum, temples almost straight and convergent posteriorly. Antennae reaching three fourth of elytral length, antennomeres 4-10 moderately flattened, each with longitudinally oval to rounded, small, semilustrous impression. Surface of head very finely imbricate-punctate, finely yellow pubescent, matt. Pronotum as long as wide, its anterior margin, anterior corners and lateral margins rounded, posterior corners obtusely rounded, posterior margin widely rounded. Surface of pronotum very finely imbricate-punctate, finely yellow pubescent, matt, semilustrous on disc. Elytra very slightly narrowing posteriorly, elytral nervation very slightly indicated, surface of elytra more finely imbricate-punctate than on head and pronotum, finely yellow pubescent, matt and velvety. Aedeagus as in Fig. 82 , laterophyses reduced and invisible from outside.

Female. Eyes smaller and less prominent than in male, head across eyes ca 0.75 times as wide as pronotum, the latter moderately wider than long. Antennae shorter, reaching almost two thirds of elytral length. Last sternite ( Fig. 83 ) with shallow trapezoidal depression and pair of oval, median longitudinal impressions separated by short longitudinal keel.

Length J ♀: 11.1-14.5 mm.

Differential diagnosis. Prothemus kantnerorum sp. nov. is very similar and closely related to P. bezdeki Švihla, 2004 , with which it has been found on the same locality. However the new species differs in sharp apical teeth of the emargination of the dorsal part of the aedeagus, smaller latero-apical teeth of this part and different shape of impressions and apical margin of the last sternite of female (cf. ŠVIHLA 2004).

Etymology. Dedicated to two of its collectors, František Kantner and his wife Liběna (České Budějovice, Czech Republic).

Distribution. Laos: Hua Phan Province.
