Data from: Resolution of a global mango and fig pest identity crisis

Hypocryphalus Hopkins, 1915 and Cryphalus Erichson, 1836 (Curculionidae: Scolytinae: Cryphalini) are significant pests of fig, mango, and other economically important fruit trees, yet have received little attention from systematists. An integrated approach using molecular and morphological evidence resolved the identities of the species feeding on mango and fig. The following taxonomic changes are proposed: Hypocryphalus mangiferae (Stebbing, 1914), stat. rev.; Hypocryphalus dilutus (Eichhoff, 1878a), stat. rev. (=Cryphalus dilutusEichhoff, 1878b, syn. n.); Hypocryphalus discretus (Eichhoff, 1878a), stat. rev. (=Cryphalus discretusEichhoff, 1878b, syn. n.; Cryphalus scabricollisEichhoff, 1878b, syn. n.; Cryphalus brevisetosus Schedl, 1943, syn. n.). We identified widespread misidentification of specimens of Hypocryphalus from mango. The pest of mango trees in Oman, Pakistan, Bangladesh and Mexico, and putatively the vector of the pathogen responsible for mango wilt, is H. dilutus, a resurrected species. The pest of figs in the Mediterranean is also H. dilutus, but a distinct genetic lineage. The globally distributed but seemingly harmless mango bark beetle is H. mangiferae: a genetically complex species in its region of origin, with a single haplotype on mango trees outside the native range. We provide DNA sequences and describe novel morphological characters for identification of these species.1915年Hopkins建立的毛小蠹属（Hypocryphalus）与1836年Erichson建立的小蠹属（Cryphalus）隶属于象甲科（Curculionidae）小蠹亚科（Scolytinae）毛小蠹族（Cryphalini），是无花果、芒果及其他经济类果树的重要害虫，但长期未得到分类学家的足够关注。本研究采用整合分子与形态学证据的研究方法，明确了取食芒果与无花果的该类群物种的分类界定。现提出以下分类学修订：芒果毛小蠹（Hypocryphalus mangiferae，Stebbing, 1914），恢复有效种地位（stat. rev.）；宽边毛小蠹（Hypocryphalus dilutus，Eichhoff, 1878a），恢复有效种地位（stat. rev.）（=原宽边小蠹Cryphalus dilutus Eichhoff, 1878b，新异名syn. n.）；阔鞘毛小蠹（Hypocryphalus discretus，Eichhoff, 1878a），恢复有效种地位（stat. rev.）（=原阔鞘小蠹Cryphalus discretus Eichhoff, 1878b，新异名syn. n.；原皱颈小蠹Cryphalus scabricollis Eichhoff, 1878b，新异名syn. n.；原短毛小蠹Cryphalus brevisetosus Schedl, 1943，新异名syn. n.）。本研究明确了芒果寄主上毛小蠹属标本存在广泛的误定情况。阿曼、巴基斯坦、孟加拉国及墨西哥的芒果树害虫，同时被推测为芒果萎蔫病致病菌的传播媒介，即为本次恢复有效地位的宽边毛小蠹（H. dilutus）。地中海地区的无花果害虫同样为宽边毛小蠹，但属于一个独特的遗传支系。全球分布但看似无害的芒果树皮小蠹为芒果毛小蠹（H. mangiferae）：该物种在其原生分布区内遗传结构复杂，而在原生分布区外的芒果寄主上仅存在一种单倍型。本研究提供了上述物种的DNA序列，并描述了用于物种鉴定的全新形态学特征。
