Stenothemus wardi sp. nov.

( Figs. 66-68 )

Type locality. Northern Myanmar, Nam Tamai river, 10 000 ft.

Type material. HOLOTYPE: J, ‘ Upper Burma, R. Nam Tamai, 10,000 ft., 8.ix.1937, F. Kingdom [sic!] Ward’ ( BMNH) . PARATYPE: same data, 1♀ ( BMNH).

Description. Coloration. Head including mouthparts rusty, slightly darkened behind eyes, antennae rusty, basal halves of antennomeres 3-6 darker, more or less sienna. Prothorax rusty, pronotum with arcuate, transverse, chestnut brown stripe at midlength. Meso- and metaster- num, scutellum, sternal part of abdomen and legs rusty. Elytra rusty, very narrow basal portion and subhumeral lateral stripe sepia, rest of elytra sparsely and indistinctly sienna spotted, spots coalescent in apical portion.

Male. Eyes moderately sized, strongly prominent, head across eyes moderately narrower than pronotum, temples straight and convergent posteriorly. Antennae reaching three fourth of elytral length, filiform, antennomeres 4-7 slightly flattened. Surface of head finely imbricate-punctate, sparsely and finely yellow pubescent, matt. Pronotum moderately wider than long, its anterior margin straight, anterior corners rounded, lateral margins widely rounded, deeply emarginate before prominent, sharp posterior corners, posterior margin widely round- ed. Surface of most of pronotum sculptured and pubescent like that of head, matt, finely and densely punctate and semilustrous on disc. Elytra distinctly dilated posteriorly, elytral nervation very slightly indicated, surface of elytra extremely finely and densely punctate, matt and velvety, with fine and short, semierect brown pubescence. Aedeagus as in Figs. 66-68 , apices of parameres concave on inner side.

Female. Antennae shorter than in male, moderately exceeding elytral midlength, elytra wider. Abdomen missing in the examined specimen.

Length J ♀: 13.0- 15.3 mm.

Differential diagnosis. Stenothemus wardi sp. nov. is based on the shape of its aedeagus related to S. harmandi species group ( India: West Bengal: Darjeeling district , Manipur, Assam; Nepal), from which it differs in shorter and terminally concave parameres and rounded apices of dorsal part of the aedeagus .

Etymology. Named in honour of its collector, botanical explorer Francis Kingdon-Ward (1885- 1958).

Distribution. Northern Myanmar.
