Description. Measurements. Males: 5.4-6.3 mm (holotype 6.3 mm), females: 6.0-7.0 mm. Dorsal side elongate oval, convex, glabrous. Body, legs and basal antennomeres metallic violet, dorsal side with oil tint, rest of antennomeres black, posterior half of last abdominal ventrite brown.

Male (holotype, Fig. 17 ). Labrum transverse, with emarginated anterior margin and rounded anterior angles, surface with six pores in transverse row bearing long seta, slightly convex. Clypeus with straight anterior corner. Anterior part of head with well developed transverse, concave, elevated keel, posteriorly produced to short process forming elevated nasal keel. Subantennal impressions with several long setae. Interantennal space as wide as transverse diameter of antennal socket. Interocular space wide, 3.4 time as wide as transverse diameter of eye. Frontal tubercles large, triangular, elevated, covered with fine microsculpture, separated by thin furrow. Vertex separated from frontal tubercles by deep straigth line, surface impunctate, glabrous. Antennae slender, 0.88 times as long body, length ratio of antennomeres equals 9-4-7-13-13-12-12-12-12-11-15.

Pronotum transverse, 1.45 times as wide as long, lustrous, glabrous, widest in anterior third, covered with very fine punctures. Surface convex in anterior half, with transverse impression at posterior third. Anterior margin almost straight, lateral margins slightly rounded at anterior half, convergent and straight posteriorly, posterior margin straight in middle, laterally slightly oblique. Anterior margin with very fine indistinct border, lateral and posterior margins thinly bordered. Anterior angles moderately swollen, oblique, posterior angles nearly rectangular, all angles with setigerous pores bearing long pale seta. Scutellum short and wide, with very widely rounded apex, impunctate, glabrous.

Elytra 1.61 times as long as wide (measured at humeral calli) and 0.66 times as long as body, oval, widest at posterior third. Surface densely covered with small confused punctures. Humeral calli developed. Epipleura relatively narrow, smooth, glabrous, lustrous, gradually narrowed towards elytral apex. Macropterous.

Last abdominal ventrite ( Figs 43, 45 ) enlarged, subtrapezoidal, median lobe with posterior margin straight, lateral parts of ventrite with large semicircular emarginations, surface of median lobe with chanelled impression slightly wider posteriorly. In lateral view, last abdominal ventrite distinctly concave in middle.

Metatrochanter not modified. Metatibia with slightly impressed and glabrous inner apical surface and apically emarginated. Tarsi: protarsomere I elongate, slightly asymmetrical with more rounded outer margin, II triangular, I slightly wider than II, length ratio of protarsomeres equals 7-6-4-9, mesotarsomere I elongate, narrow, parallel, length ratio of mesotarsomeres equals 8-6-4-10; metatarsomere I elongate triangular, length ratio of metatarsomeres equals 11-7-4-10.

Aedeagus ( Fig. 26 ) flat, with apical third triangular, middle part wide and subparallel. Dorsal surface with two long parallel carinae medially and two shorter oblique carinae laterally. In lateral view, aedeagus strongly curved in apical half.

Female. Metatibia not modified. Pygidium with small apical incision. Spermatheca with elongate nodulus, cornu C-shaped ( Fig. 53 ). Gonocoxae as in Fig. 67 . Sternite VIII drop-shaped with widely rounded apical margin, tignum thin with slightly wider middle part, 1.8 times longer than sternite VIII ( Fig. 60 ).

Differential diagnosis. Having not modified male metatrochanters and enlarged last abdominal ventrite with channeled median lobe, Agelopsis malaisei sp. nov. is similar to A. belousovi and A. konstantinovi sp. nov. The aedeagus of A. malaisei sp. nov. has strongly curved apical part and carinate dorsal surface ( Fig. 26 ) while aedeagus is lanceolate with pointed tip, ventrally with two wing-like lamellae in A. belousovi ( Fig. 20 ) and aedeagus is transversely cut in A. konstantinovi sp. nov. ( Fig. 25 ). Males of Agelopsis malaisei sp. nov. have abdominal ventrite IV not modified and last abdominal ventrite relatively flat and in lateral view ditinctly concave ( Figs 43, 45 ). Similar structure of abdomen can be found in males of A. belousovi but abdominal ventrite IV has two small flat lamellae in middle and last abdominal ventrite is raised ( Fig. 32–34 ).

Distribution. Myanmar.

Etymology. Dedicated to René Edmond Malaise, a Swedish entomologist, who collected the type series.
