Habronychus (Habronychus) kantnerorum sp. nov.

( Figs. 75-78 )

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, 8.-17.v.2004, F. & L. Kantner lgt.’ ( NMPC) . PARATYPE: same data, 1 ♀ ( NMPC).

Description. Coloration. Head sepia, portions in front of antennal pits including mandibles pale lemon yellow, maxillary palpi and clypeus sepia, spots on frons behind eyes and lateral stripes behind eyes indistinctly terra-cotta.Antennae sepia, base of antennomere 1 pale lemon yellow. Prothorax chestnut brown, pronotum with pair of longitudinal, sinuate stripes and with both anterior and posterior margins terra-cotta. Meso- and metasternum, scutellum and ventral part of abdomen chestnut brown, legs chestnut brown in female, femora with longitudinal paler bands in male, elytra dark blood red.

Male. Eyes relatively small, moderately protruding, head across eyes ca 1.25 times as wide as pronotum, temples straight and convergent posteriorly. Antennae slightly exceeding elytral apex, antennomeres 4-11 very slightly flattened, antennomeres 5-9 with almost invisible oval impression. Surface of head finely imbricate-punctate and yellow pubescent, matt. Pronotum slightly longer than wide, its anterior margin widely rounded, anterior corners very slightly rounded, almost rectangular, lateral margins slightly sinuate, slightly diverging posteriorly, posterior corners slightly rounded, almost rectangular, posterior margin widely rounded. Surface of pronotum sculptured and pubescent like that of head, matt, with short median longitudinal carina in posterior half. Elytra parallel-sided, elytral nervation slight but distinct, surface of elytra finely rugulose-lacunose with fine and dense red pubescence, matt. Aedeagus as in Figs. 75-77 .

Female. Antennae shorter than in male, slightly exceeding two thirds of elytral length, elytra very slightly dilated posteriorly, last abdominal sternite as in Fig. 78 .

Length J ♀: 5.0- 5.8 mm.

Differential diagnosis. Habronychus kantnerorum sp. nov. belongs to a group of species with moderately but distinctly costate elytra and with very similar aedeagi, including H. (s. str.) lineaticeps ( Pic, 1914) from northern Vietnam, H. (s. str.) parallelicollis ( Pic, 1921) from Yunnan and H. (s. str.) distinctecostatus ( Pic, 1917) from northern Vietnam. All species were originally described in the genus Lycocerus Gorham, 1889 . The new species seems to be most closely related to H. lineaticeps , which has been found at the same locality; H. kantnerorum sp. nov. differs from the latter species in strongly reduced pale coloration of the head, predominantly dark pronotum, shorter median lobe and slightly different parameres and dorsal part of the aedeagus (cf. PIC 1914 and Figs. 75-77, 79-81 ). The other two mentioned species also possess much paler pronotum, at most with a narrow median longitudinal stripe (cf. PIC 1917, 1921).

Etymology. Dedicated to its collectors, František Kantner and his wife Liběna (České Budě- jovice, Czech Republic).

Distribution. Laos: Hua Phan Province.
