Notoxus hilaris sp. nov.

( Figs. 11 , 75 , 81 )

Type locality. Myanmar, Kachin State, Myitkyina, about 350 m a.s.l.

Type material. HOLOTYPE: J, ‘ MYANMAR: Kachin State, Myitkyina, Sumpra Hotel 26. - 27.5.1999, ca. 350 m, at light, leg. Schuh & Schillhammer (55)’ ( NHMW).

Description. Male (holotype). Body length 3.4 mm. Head and pronotum reddish brown, pronotum largely darker. Elytra pale reddish to yellowish, with conspicuous brown black markings ( Fig. 81 ); only humeral spots touching lateral margins. Legs and antennae reddish.

Body only moderately glossy, rather finely, densely and evenly punctured; pronotum with some scattered coarser punctures; margins of punctures on elytra not quite smooth, very finely sculptured. Body setation mostly appressed to subdecumbent; pronotum with some conspicuously long, suberect to erect setae antero-laterally; elytra with numerous, distinctly longer suberect setae. Antebasal setose band of pronotum conspicuous, widely interrupted medially. Protibiae in addition to fine setation with short, stiff setae forming dense fringe on median longitudinal edge.

Head with rather large eyes. Antennae long, only moderately enlarged in terminal third. Pronotum as wide as head across eyes, globose to moderately elongate in dorsal view. Pronotal horn moderately long and slender, largely subparallel, armed with 4–5 distinctly protruding lateral lobules on each side and simple wider apical lobule; horn crest only moderately raised, evenly lowering towards horn apex, its lateral margins feebly marked by series of somewhat coarser, distinctly separate lobules / rugules; dorsal surface rather evenly and densely covered by distinct rounded rugules. Elytra 2.2 times as long as wide; humeri distinctly protruding; omoplates and postbasal moderately indicated; elytral apices indistinctly modified, unevenly rounded to subtruncate, with rounded gland opening near rather rounded lateral angle. Protibiae distinctly modified, moderately sinuous, twice angulately produced and flatly impressed, with longitudinal edge on median side ( Fig. 75 ).Abdominal sternum VII evenly rounded posteriorly. Tergum VIII forming simple, evenly arched sclerite. Aedeagus as figured ( Fig. 11 ).

Female. Unknown.

Differential diagnosis. Notoxus hilaris sp. nov. can be easily distinguished from all members of the N. indicus species-group by rather distinctive colouration of the elytra, shape and modified setation of the male protibiae and by morphology of the aedeagus.

Etymology. From Latin word hilaris (merry, hilarious); named in reference to the conspicuous markings of the elytra.

Distribution. Myanmar.
