Notoxus safraneki sp. nov.

( Figs. 35 , 58 , 87 )

Type locality. Laos, Borikhan Province, 20 km north of Muang Pakxan, environs of Borikhan.

Type material. HOLOTYPE: J, ‘ LAOS – Borikhan prov. , BORIKHAN env., 20 km N of Muang Pakxan, 16.–20.v.2003. O. Šafránek leg.’ ( NMPC) . PARATYPES: 3 JJ, same data as holotype ( ZKDC).

Description. Male (holotype). Body length 3.1 mm. Head and pronotum dark brown to brown black, pronotal horn somewhat paler, with reddish tinge. Elytra reddish, with distinct black markings ( Fig. 87 ); subapical spots vaguely indicated, connected along suture with humeral spots; large lateral spots connected along lateral margins with humeral spots. Legs and antennae reddish.

Head and pronotum densely punctured, less glossy than elytra. Pronotum coarsely rugose antero-laterally, its punctation uneven, distinctly coarser and nearly contiguous dorso-medially, sparser and finer dorso-laterally. Elytra rather glossy; basal half punctures mostly very coarse, distinctly spaced. Body setation rather long and conspicuous, mostly subdecumbent to decumbent; pronotum with numerous conspicuously long, suberect to erect setae, especially antero-laterally; setation of elytra generally somewhat more raised, decumbent, with numerous, moderately longer, suberect setae. Antebasal setose band of pronotum widely interrupted dorso-medially.

Head with rather large and conspicuous eyes. Antennae moderately long, distinctly enlarged in terminal third. Pronotum slightly wider than head across eyes, rather globose in dorsal view. Pronotal horn moderately long and slender, narrowing towards apex, armed with 3–4 distinctly protruding lateral lobules on each side and simply rounded apical lobule ( Fig. 58 ); horn crest only moderately raised, evenly lowering towards horn apex, its lateral margins very feebly marked by series of somewhat coarser, distinctly spaced lobules / rugules; dorsal surface evenly and rather densely covered by distinct rounded rugules. Elytra 1.8 times as long as wide; humeri distinctly protruding; omoplates moderately indicated and postbasal impression nearly indistinct; elytral apices modified, subtruncate, with rounded opening of gland near distinctly protruding lateral angle. Legs simple. Abdominal sternum VII simple, evenly rounded posteriorly in ventral view. Tergum VIII forming simple, evenly arched sclerite. Aedeagus as figured ( Fig. 35 ; dorsal plate of tegmen partly abrupt apically).

Female. Unknown.

Variation. Body length (J ♀) 2.6–3.1 mm. Rather variable in prominence of dark markings on elytra. The markings may be rather vague, except for distinct lateral spots, or conspicuous, with lateral spots distinctly connected with median strip, forming cross-shaped marking.

Differential diagnosis. Notoxus safraneki sp. nov. can be easily recognized within the N. noctivagus species-group by the rather narrow pronotal horn with conspicuous lobules on the margins ( Fig. 58 ), less elongate elytra with a distinct dark markings ( Fig. 87 ), coarsely and densely punctured median strip of the pronotal disc, simple male sternum VII, and by detailed morphology of the aedeagus.

Etymology. Dedicated to its collector, Ondřej Šafránek (Jiřetín pod Jedlovou, Czech Republic), well-known Czech traveller and entomologist.

Distribution. Laos.
