Key to the species of the genus Amphicrossus of the Indo-Malayan region with paramedial brushes of long hairs on male elytra 1 Antennái club narrow, almost twice as long as wide; antennomeres 2 about 3 times and antennomere 3 about 4 times as long as wide; hypopygidium slightly emarginate and with a brush of hairs along base of movable lobe; pygidium widely rounded at apex; paramedial brushes of hairs on elytra almost in anterior fourth; posterior edge of pronotum very slightly oblique at posterior angles. 3.8-5.3 mm. Figs 23-33. Malaysia (Borneo), Indonesia (Mentawei) A. angusticlavis sp. n. - Antennái club oval or subovoid, at most 1.5 times as long as wide; antennomeres not so narrow, antennomere 2 usually not more than twice as long as wide; combination of other character different 2 2 Paramedial brushes of hairs on elytra strongly developed (thick and dense, much longer than antennái club) and located in anterior third; dorsum unicolorous; hypopygidium slightly emarginate and with a short and comparatively wide process before movable median lobe; anterior edge of median plate of mesosternum with a short protuberance 3 Paramedial brushes of hairs on elytra less developed (thinner and frequently not so dense, shorter than antennái club); if these brushes nearly longer than antennái club (A. japonicus, A. hisamatsui, A. hirtus sp. n., A. triparcus sp. n.), then they are located behind anterior third of elytra or much thinner (besides, elytra of A. hirtus sp. n. with indistinct pale spots along the middle); combination of other characters different, including structure of apex of hypopygidium 4 3 Pygidium widely rounded at posterior edge and with very long cilia along it (markedly longer than those along lateral sides of pronotum and elytra); hypopygidium with comparatively narrow emargination and wider median process; apices of lateral lobes of tegmen shorter, blunt and with a very long preapical brush; posterior edge of pygidium widely rounded; median process at bottom of apical emargination of hypopygidium with gently curved outline. 4.0-5.2 mm. Figs 101-108. Myanmar (Burma) A. solodovnikovae sp. n. Pygidium subtruncate at posterior edge and with moderately long cilia along it (about as long as those along lateral sides of pronotum and elytra); hypopygidium with comparatively wide emargination and narrower median process; apices of lateral lobes of tegmen longer, subacute and with a
