Notoxus garuda sp. nov.

( Fig. 18 )

Type locality. Thailand, Nakhon Ratchasima Province, Pak Chong.

Type material. HOLOTYPE: J, ‘ THAILAND, Khorat, Pakchong, Musi, Vil. 9, Khlong Yai VII–15–69; u. v. light G. Ballmer // UCRC // Notoxus inbasalis Pic det. G. Uhmann 1984’ ( USNM).

Description. Male (holotype). Body length 3.3 mm. Body largely brown, pronotal horn and posterior collar partly reddish; elytra with distinct paler markings: two rather wide transverse bands, narrowly interrupted on suture, vaguely touching lateral margins; elytral apices dark coloured. Legs and antennae dark brown, at places with reddish tinge. Pronotal disc rather distinctly, evenly punctured. Elytra moderately glossy; punctures in basal half mostly rather coarse, moderately larger than those on pronotum, distinctly spaced, dot-like with smooth margins. Body setation conspicuous, mostly subdecumbent, with numerous longer, suberect to erect setae, conspicuously long on pronotum antero-laterally. Antebasal setose band of pronotum widely interrupted dorso-medially.

Head with medium-sized eyes; tempora nearly straightly narrowing posteriad. Antennae moderately long, moderately enlarged in terminal third. Pronotum nearly 1.2 times as wide as head across eyes, rather globose in dorsal view. Pronotal horn moderately long and slen- der, slightly narrowing towards apex, armed with 3 distinct separate lobules laterally on each side, its wider apical and subapical lobules nearly fused; 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 twice as long as wide; humeri distinctly protruding; omoplates and postbasal impression moderately indicated; elytral apices modified, subtruncate, with rounded gland opening near distinctly protruding lateral angle. Abdominal sternum VII nearly simple, its posterior margin slightly emarginate medially in ventral view. Legs simple. Tergum VIII forming simple, evenly arched sclerite. Aedeagus as figured ( Fig. 18 ).

Female. Unknown.

Differential diagnosis. Notoxus garuda sp. nov. is externally similar to N. ales ( Fig. 83 ), but differs by somewhat more slender body and darker colouration (no reddish tinge on elytral base and pronotum). It can be easily recognized by the morphology of the aedeagus (cf. Figs. 18 versus 16).

Etymology. Named after the Garuda, a bird-like creature from both Hindu and Buddhist mythology, featured as the national symbol of Thailand. Noun in apposition.

Distribution. Thailand.
