MATERIAL. Holotype, ♂, N Myanmar (Burma), 50 km E Putao, env. Nan Thi , 950 m, 11–16.V.1998, S. Murzin leg. ( ICM). Description. Male. Dark brown to black; frons, clypeus, labial palpomeres 1–3, pronotum, prosternum, mesoventrite, scutellum and trochanters orange testaceous ( Fig. 31 ).

Vertex flat, finely punctate, shining, with short hairs. Eyes small, interocular distance ca. 2.9 times greater than eye diameter. Clypeus transverse, trapezoidal, truncate anteriorly. Palps slender, ultimate palpomeres elongate, considerably longer and wider than preceding palpomeres. Antennae filiform, attaining to elytral five sixths; antennomere 3 ca. 2.1 times longer than antennomere 2 and ca. 1.2 times longer than antennomere 4; antennomeres with short semi-erect pubescence.

Pronotum transverse, ca. 1.9 times wider than long, basally almost straight, with small tooth before posterior angle; anteriorly slightly convex and feebly incised medially; disk medially with broad shallow impression; anterior angles rounded; sides with hairy ‘cap’, constituting ca. half of side’s length, and relatively broad opening at posterior angle; posterior angle little produced. Scutellum triangular, rounded at apex ( Fig. 31 ).

Elytra ca. 2.5 times longer than wide at humeri, slightly widened posteriorly, with coarse dense punctuation and traces of two longitudinal veins in sutural halves. Pubescence short and sub-erect, not concealing the punctuation. Femoris and tibiae straight, femoris relatively robust, tibiae narrow; ratio of hind leg tarsomeres — 1:0.9:0.8:0.7:1.

Spiculum gastrale very narrow, needle-shaped, parallel-sided. Aedeagus with sub-triangular ventral plate, dentate at sides in the middle and concave and denticulate at distal margin; dorsal plate triangular, semicircular in lateral view; laterophyses distinctly diverging, slightly bent in distal half, narrowed at apex, not denticulate; median lobe with prominent robust spines ( Figs 32–34 ).

Female. Unknown.

Length: 6.3 mm. Width (humerally): 1.9 mm.

DIAGNOSIS. Podosilis putaoensis sp.n. is quite unlike any other Podosilis species due to its pronotal structure ( Fig. 31 ), and also unique in having the triangular shape of the dorsal plate and semicircular in lateral aspect dorsal plate of the aedeagus ( Figs 32–34 ).

ETYMOLOGY. The new species is named after the type locality.
