Cryphalus Erichson, 1836 is a taxonomically challenging genus. It is particularly speciose in Asia. Many species are minor pests of fruit tree crops and forest products. We review collections from East Asia, using external morphology, internal morphology and genetic markers with a focus on sub-tropical species from fruit trees. Four new species are described; Cryphalus gnetivorus Johnson, sp. nov., C. itinerans Johnson, sp. nov., C. morivorus Johnson, sp. nov., and C. paramangiferae Johnson, sp. nov. Ten species are redescribed to enable accurate identification: C. artocarpus (Schedl, 1939), C. dilutus Eichhoff, 1878, C. dorsalis (Motschulsky, 1866), C. exiguus Blandford, 1894, C. kyotoensis Nobuchi, 1966, C. lipingensis Tsai & Li, 1963 (= C. kesiyae Browne, 1975, syn. nov.), C. mangiferae Stebbing, 1914 (= C. artestriatus Browne, 1970, syn. nov.), C. meridionalis (Nobuchi, 1975), C. scopiger Berger, 1917, and C. viburni Stark, 1936. Additional records from new localities and new hosts are also presented.

东亚金龟子Erichson（Curculionidae，Scolytinae）：新物种，新同义词和物种重新命名

Cryphalus Erichson，1836年，是一个在分类学上具有挑战性的属。在亚洲尤其如此。许多物种是果树作物和森林产品的次要害虫。我们使用外部形态，内部形态和遗传标记对东亚地区的藏品进行审查，重点关注果树上的亚热带物种。描述了四个新物种。Cryphalus gnetivorus约翰逊，sp。C. itinerans Johnson，11月。十一月，C。morivorus Johnson，sp。十一月，和C. paramangiferae Johnson，sp。十一月 重新描述了十个物种以实现准确识别：面包果角果（Schedl，1939），稀释角果树Eichhoff，1878，背侧角果（Motschulsky，1866），弯曲角果布兰福德（C. exiguus Blandford），1894，京都角枝菌（C. kyotoensis Nobuchi），1966，C. lipingensis Tsai＆Li，1963（= C. kesiyae Browne，1975，同上，十一月），C. mangiferae Stebbing，1914（= C. artestriatus Browne，1970，同上。
