( Figures 1B View Figure 1 , 2 View Figure 2 D–F, 3D–G, 4C,D)
Description
Body ( Figure 1B View Figure 1 ) length 3.7–3.8 mm, parallel-sided, depressed above, covered with coarse punctures and golden pubescence, brownish black to black and glossy. Head subglobular, slightly broad, about 1.05 times as wide as long; eye protruding, as long as temple; antennae ( Figure 2D View Figure 2 ) threadlike, pubescent, reaching anterior third of elytra; scape oval and robust, about 2.0 times as long as wide; pedicel to antennomere 10 subtrapezoidal, width of antennomeres 2–6 almost same, antennomeres 6–10 getting slightly wider; pedicel about 2.44 times as long as wide, 0.6 times as wide and 0.73 times as long as scape; antennomere 3 about 2.78 times as long as wide, 1.14 times as long as pedicel; antennomere 7 about 2.32 times as long as wide; antennomere 8 about 2.1 times as long as wide; antennomere 9 about 2.0 times as long as wide; antennomere 11 longest, 3.81 times as long as wide; gular sutures parallel, gular plate narrow, 0.10 times as wide as head; postgena well convex. Pronotum ( Figure 2E View Figure 2 ) subhexagonal and convex, covered with coarse punctures, widest in anterior third, anterior third of midline depressed, middle area longitudinally elevated, U-shaped depression present behind medial elevation, lateral margins weakly crenulate, post-lateral margin clearly emarginate, 1.11 times as wide as long, almost as wide as and 0.94 times as long as head. Elytra ( Figure 2F View Figure 2 ) unicolour, dilated posteriorly, punctured coarsely, 1.03 times as long as wide, 1.50 times as wide and 1.71 times as long as pronotum. A pair of wing folding patches present on tergites IV and V; posterior margin of tergite VII with apical fringe.
Male. Front tarsus broad. Medial posterior area of sternite VII depressed with numerous obtuse macro setae, posterior margin shallowly emarginate ( Figure 3D View Figure 3 ); anterior margin of tergite VIII deeply sinuate, posterior margin slightly emarginate ( Figure 3E View Figure 3 ); anterior projection of sternite VIII wider than half of sternite, posterior margin emarginate ( Figure 3F View Figure 3 ); sternite IX ( Figure 3G View Figure 3 ) narrow, posterior third of lateral margin almost parallel, basal part of dorsal surface with short longitudinal carina, apical area pubescent with two long setae. Median lobe of aedeagus slender and weakly sinuate, narrowed apically, apex of median lobe upturned strongly ( Figure 4C,D View Figure 4 ); parameres parallel, almost as long as median lobe, a little longer than basal bulb, posterior quarter somewhat constricted ( Figure 4D View Figure 4 ).

Remarks
Archaeoboreaphilus macrothorax sp. nov. can be distinguished from other species by the dark brownish appendages except for A. yasutoshii . Archaeoboreaphilus macrothorax sp. nov. differs from A. yasutoshii in the following characters: pronotum broad and post-lateral margin distinctly emarginate; male sternite VII with macro setae on depressed posterior area; aedeagus less slender and median lobe weakly sinuate in dorsal aspect.
Etymology
The specific name, macrothorax , refers to the large size of pronotum.
