Abstract

Abstract. Two new species-groups of Lycocerus Gorham are defined, L. kuatunensis group and L. continuatus group, which could be differentiated from all others except L. canthariformis (Ishida, 1986) by the aedeagus with conjoint dorsal plates of parameres. The L. kuatunensis group is composed of five species, including L. kuatunensis (Wittmer, 1995), L. svihlai (Wittmer, 1995) comb. nov., L. nigroapicis Y. Yang et X. Yang, 2013, L. bifurcatus Y. Yang et X. Yang, 2013, and L. nigrigenus Y. Yang et X. Yang, 2013, and the L. continuatus group consists of two species, L. continuatus sp. nov. and L. parameratus Y. Yang et X. Yang, 2013. These two groups differ from each other in the aedeagus possessing longitudinal ridges on inner surface of conjoint dorsal plates of parameres or not, laterophyses compressed or slender, accessory gland uniformly thin or slightly enlarged apically. A morphological phylogenetic analysis shows that the two new groups are closer to the L. canthariformis subgroup of the L. vitellinus group due to the similarity in their aedeagi. The above species are provided with habitus photos, aedeagi, reproductive systems and abdominal sternites VIII of female. A key to the species and a distribution map are provided.

文章标题狼尾蛾(鞘翅目:斑蛾科)两新种群及其系统发育地位的初步探讨

摘要定义了两个新的Lycocerus Gorham种群，L. kuatunensis组和L. continuatus组，它们可以通过参数背板联合的aedeagus与L. canthariformis (Ishida, 1986)以外的所有其他种群区分开来。L. kuatunensis群由5种组成，包括L. kuatunensis (Wittmer, 1995)、L. svihlai (Wittmer, 1995)梳子。nov.， L. nigroapicis Y. Yang et x Yang, 2013, L. bifurcatus Y. Yang et x Yang, 2013, L. nigrigenus Y. Yang et x Yang, 2013, L. continuatus群由L. continuatus sp. 11和L. parameratus Y. Yang et x Yang, 2013两种组成。这两个类群的不同之处在于:在关节背板的内表面具有纵脊或不具有纵脊，侧体压缩或细长，副腺均匀薄或顶部稍大。形态学系统发育分析表明，这两个新类群在aedeagi上具有相似性，更接近于L. canthariformis亚群的L. vitellinus亚群。上述物种均有雌性的习性照片、aedeagi、生殖系统和腹部胸骨VIII。提供了一个物种的钥匙和分布图。
